The male molding surface fastener which is produced by molding a synthetic resin is generally formed by arranging a plurality of male fastening elements having a mushroom shape or the like on the upper surface of the flat base portion.

此種具有公型之面扣結件之面扣結件製品目前廣泛用於多種多樣之商品，例如亦多用於如拋棄式尿布、乳幼兒之尿布套、保護手足之關節等之護體、腰用整姿內衣(腰痛帶)、手套等穿脫至身體般之商品。 Such face-to-knot products having a male-face fastener are currently widely used in a wide variety of products, such as a disposable diaper, a diaper cover for a baby, a joint for protecting the joints of the hands and feet, and a waist. Use a full-length underwear (back pain belt), gloves, etc. to wear off to the body-like goods.

在用於拋棄式尿布等之成形面扣結件中，作為公型扣合元件之代表性形態，J字狀之形態、棕櫚樹狀之形態、蘑菇狀之形態等廣為所知。例如，J字狀之扣合元件具有自基材部朝上方突出，並且上端部鉤狀地彎曲之形態。具有此種J字狀之扣合元件之成形面扣結件記載於國際公開第1998/014086號公報(對應於專利文獻1：日本專利特表2001-501120號公報)等。 In a molded surface fastener for use in a disposable diaper or the like, a J-shaped form, a palm-like form, a mushroom-like form, and the like are widely known as a representative form of a male snap element. For example, the J-shaped fastening element has a shape in which the upper end portion protrudes upward and the upper end portion is bent in a hook shape.

例如具有如上所述之J字狀之扣合元件或棕櫚樹狀之扣合元件之成形面扣結件於使母型之面扣結件之線圈(例如不織布之纖維)扣合之情形時，線圈難以自J字狀或棕櫚樹狀之扣合元件拔出。因此，具有J字狀或棕櫚樹狀之扣合元件之成形面扣結件具有對母型面扣結件具備較高之剝離強度之傾向。 For example, when the forming surface fastening member having the J-shaped fastening member or the palm-shaped fastening member as described above is engaged with the stitch of the female surface fastener member (for example, the fiber of the non-woven fabric), It is difficult for the coil to be pulled out from the J-shaped or palm-like fastening element. Therefore, the forming surface fastener having a J-shaped or palm-like fastening member has a tendency to have a high peeling strength to the female surface fastener.

具有該等J字狀或棕櫚樹狀之複數個扣合元件之成形面扣結件一般係藉由如下方法而製造：使用在外周面部形成有複數個具備對應於該扣合元件之形狀之模腔之模輪，連續地進行合成樹脂之成形。又，於利用模輪連續地成形J字狀或棕櫚樹狀之扣合元件之情形時，需要成形為使扣合元件之上端部朝1個方向或朝成為相反之朝向之2個方向鉤狀地彎曲並且突出之形狀。 Forming surface fasteners having a plurality of fastening elements of such J-shaped or palm-like shapes are generally It is produced by continuously forming a synthetic resin by using a plurality of mold wheels having a cavity having a shape corresponding to the fastening element formed on the outer peripheral surface. Further, in the case where the J-shaped or palm-shaped fastening elements are continuously formed by the die wheel, it is necessary to form the hooks in the two directions of the upper end of the fastening element in one direction or the opposite direction. The shape of the ground is curved and protrudes.

然而，於先前之成形中，為了自模輪之模腔將扣合元件無損傷地拔出，僅能使鉤狀之扣合頭部之朝向朝著沿著成為成形體之搬送方向之機械方向(MD)之方向。因此，先前無法連續地製造具有鉤狀之扣合頭部之朝向朝著與機械方向(MD)交叉(正交)之交叉方向(CD)之扣合元件之成形面扣結件。 However, in the prior forming, in order to pull the fastening element out of the mold cavity of the mold wheel without damage, only the direction of the hook-shaped fastening head can be oriented toward the mechanical direction along the conveying direction of the forming body. The direction of (MD). Therefore, the forming surface fastener of the fastening member having the hook-shaped fastening head toward the crossing direction (orthogonal) in the machine direction (MD) cannot be continuously manufactured.

又，於先前之J字狀或棕櫚樹狀之扣合元件之情形時，因扣合元件之上端部鉤狀地彎曲，故而扣合元件之上端面(頂端面)之面積較小。因此，當觸摸成形面扣結件之成為扣合面之上表面側時，與肌膚接觸之面積變小。因此，於將此種成形面扣結件用於例如拋棄式尿布或尿布套等容易與肌膚接觸之製品、或要求柔軟之觸感之製品之情形時，存在製品之肌膚觸感變差之情況。 Further, in the case of the previous J-shaped or palm-like fastening member, since the upper end portion of the fastening member is bent in a hook shape, the area of the upper end surface (tip surface) of the fastening member is small. Therefore, when the touch forming surface fastening member becomes the upper surface side of the fastening surface, the area in contact with the skin becomes small. Therefore, when such a formed surface fastener is used for a product which is easily in contact with the skin such as a disposable diaper or a diaper cover, or a product which requires a soft touch, there is a case where the touch of the product is deteriorated. .

進而，於先前之J字狀或棕櫚樹狀之扣合元件中，自基材部豎起之基端部或桿部容易較細地形成。因此，亦考慮到將母型面扣結件強力地壓抵於公型之成形面扣結件(或，將公型之成形面扣結件強力地壓抵於母型面扣結件)而使兩者扣合之情形時，扣合元件之基端部或桿部容易因按壓力而折曲，而導致成形面扣結件之破損。 Further, in the conventional J-shaped or palm-shaped fastening element, the base end portion or the rod portion which is erected from the base material portion is easily formed finely. Therefore, it is also considered that the female profile fastening member is strongly pressed against the male molding surface fastening member (or the male molding surface fastening member is strongly pressed against the female profile fastening member). When the two are fastened, the base end portion or the rod portion of the fastening member is easily bent by the pressing force, and the forming surface fastener is broken.

另一方面，於蘑菇狀之扣合元件中，因於扣合元件之上端部形成有圓盤狀之扣合頭部，故而能夠使扣合元件之上端面以較J字狀或棕櫚樹狀之扣合元件大之面積露出於上方。因此，具有蘑菇狀之扣合元件之成形面扣結件具有肌膚觸感佳之特徵。又，易於使扣合元件之桿部較粗地形成，故而即便受到如上所述般之按壓力，桿部亦不易折曲，能夠穩定地維持扣合元件之形狀。 On the other hand, in the mushroom-shaped fastening element, since the upper end portion of the fastening element is formed with a disc-shaped engaging head, the upper end surface of the fastening element can be made in a J shape or a palm tree shape. The large area of the snap-fit component is exposed above. Therefore, the formed surface fastener having the mushroom-like fastening member has a characteristic of good skin feel. Further, since it is easy to form the rod portion of the engaging element to be thick, even if the pressing force is applied as described above, the rod portion is less likely to be bent, and the shape of the engaging member can be stably maintained.

進而，於具有蘑菇狀之扣合元件之成形面扣結件中，當使成為母型面扣結件之不織布扣合時，能夠使複數個線圈穩定地扣合。然而，於蘑菇狀之扣合元件中，扣合元件之上端部並未如J字狀或棕櫚樹狀之形態般鉤狀地彎曲。因此，於蘑菇狀之扣合元件之情形時，亦存在與J字狀或棕櫚樹狀之扣合元件相比剝離強度變弱之情況，而謀求改善。 Further, in the molded surface fastener having the mushroom-shaped fastening member, when the non-woven fabric to be the mother-shaped fastener is fastened, a plurality of stitches can be stably engaged. However, in the mushroom-shaped fastening element, the upper end portion of the fastening element is not bent in a hook shape like a J-shape or a palm-like shape. Therefore, in the case of a mushroom-shaped fastening element, there is a case where the peeling strength is weaker than the J-shaped or palm-shaped fastening element, and the improvement is made.

又，一般而言，公型之面扣結件容易根據成為母型面扣結件之不織布之構造等而使線圈之扣合率或剝離強度等變化，存在公型面扣結件之性能受與不織布之配合性左右之情況。因此，為了能夠根據不織布，又，根據製品用途而進行公型面扣結件之選擇，而期望藉由增加扣合元件之形態之變化等而豐富地齊備各種類型之公型成形面扣結件。 Further, in general, the male face fastener is easily changed in accordance with the structure of the non-woven fabric which becomes the female profile fastening member, etc., and the performance of the male profile fastening member is affected by the buckle ratio or the peel strength. The situation with the compatibility with non-woven fabrics. Therefore, in order to be able to select the male-face fastener according to the non-woven fabric and the use of the product, it is desirable to enrich the various types of male forming surface fasteners by increasing the shape of the fastening component and the like. .

Further, each of the engaging elements has a rod portion that rises from the base portion, and at least one hook portion that protrudes from the upper end portion of the rod portion in the second direction.

進而，鉤部具有使第1方向之尺寸朝該鉤部之鉤前端遞減之前端較窄之形狀。該鉤部之下表面局部地具有壓縮面，該壓縮面藉由在成形步驟中自成形模具之模腔面(尤其是，模腔面之邊緣部)接受按壓壓縮而較鉤部之上表面光滑地形成。尤其是，認為此種鉤部下表面之壓縮面藉由在自成形模具脫模時受到按壓壓縮，而較鉤部之上表面硬地形成。 Further, the hook portion has a shape in which the dimension in the first direction is tapered toward the front end of the hook portion of the hook portion. The lower surface of the hook portion has a compression surface locally, the compression surface being formed in the forming step The cavity surface of the self-forming mold (in particular, the edge portion of the cavity surface) receives compression compression and is formed smoother than the upper surface of the hook portion. In particular, it is considered that the compressed surface of the lower surface of the hook portion is pressed and compressed at the time of demolding from the forming mold, and is harder than the upper surface of the hook portion.

此處，本發明中之第1方向係指沿著於成形面扣結件之製造步驟(成形步驟)中成形面扣結件或一次成形體所前進之機械方向(M方向或MD)之方向。又，基材部於第1方向呈長形係指於成形步驟中基材部沿機械方向長形地形成。換言之，有時亦會於利用成形步驟使成形面扣結件成形之後對該成形面扣結件進行切斷等加工，該情形時，亦存在切斷後之成形面扣結件之基材部於第1方向(機械方向)不呈長形之情況。本發明中之第2方向係指與機械方向(MD)正交之交叉方向(C方向或CD)，係指長形地成形之基材部之寬度方向。 Here, the first direction in the present invention means the direction of the mechanical direction (M direction or MD) in which the forming surface fastener or the primary molding body advances in the manufacturing step (forming step) of the forming surface fastening member. . Further, the fact that the base material portion is elongated in the first direction means that the base material portion is elongated in the machine direction in the forming step. In other words, in some cases, the forming surface fastener is formed by cutting, and then the forming surface fastener is cut or the like. In this case, the base portion of the formed surface fastener is also cut. The first direction (mechanical direction) is not elongated. The second direction in the present invention means an intersecting direction (C direction or CD) orthogonal to the machine direction (MD), and refers to a width direction of the base portion which is formed in an elongated shape.

具有如上所述之壓縮面局部地形成於下表面並且具有前端較窄之形狀之鉤部、及桿部之本發明之扣合元件具備與先前之J字狀、棕櫚樹狀、及蘑菇狀不同之新穎之形態。於具有此種扣合元件之本發明之成形面扣結件中，容易使柱狀之桿部較粗地形成。因此，即便對本發明之成形面扣結件強力地壓抵母型面扣結件而受到較大之按壓力，桿部亦不易折曲，能夠穩定地維持扣合元件之形狀。又，桿部易於確保較大之強度，故而能夠使對母型面扣結件之剪切強度增大。 The fastening member of the present invention having the compression surface having the compression surface partially formed on the lower surface and having a narrow front end and the rod portion is different from the previous J-shaped, palm-like, and mushroom-shaped The novel form. In the forming surface fastener of the present invention having such a fastening member, the columnar stem portion is easily formed to be thick. Therefore, even if the forming surface fastener of the present invention is strongly pressed against the female surface fastener and subjected to a large pressing force, the rod portion is not easily bent, and the shape of the fastening member can be stably maintained. Further, since the rod portion is easy to secure a large strength, the shear strength to the female surface fastener can be increased.

進而，該情形時，能夠對母型面扣結件較深地壓入本發明之成形面扣結件。藉此，能夠將成形面扣結件之各扣合元件較深地***至母型面扣結件之線圈之根部附近，從而使線圈牢固地扣合至扣合元件。 Further, in this case, the molding surface fastener of the present invention can be pressed deep into the female surface fastener. Thereby, each of the fastening elements of the forming surface fastening member can be inserted deeper into the vicinity of the root of the stitch of the female surface fastening member, so that the stitch is firmly fastened to the fastening member.

又，於本發明中，係以使桿部之上表面較大地露出於上方之方式形成扣合元件之頂面(上表面)。因此，於自成為扣合面之上表面側觸摸本發明之成形面扣結件之情形時，桿部之上表面易於較寬地與肌膚接觸。又，因鉤部係相對於桿部較小地形成，故而當觸摸扣合元件時，能夠減小鉤部對其觸感產生之影響(不適感)。因此，本發明之成形面扣結件與例如具有先前之J字狀或棕櫚樹狀之扣合元件之成形面扣結件相比，能夠穩定地獲得良好之肌膚觸感或觸感。 Further, in the present invention, the top surface (upper surface) of the fastening member is formed such that the upper surface of the rod portion is exposed to a large extent. Therefore, touch the hair on the surface side of the upper surface of the fastening surface In the case of a molded surface fastener, the upper surface of the stem is likely to be in wide contact with the skin. Further, since the hook portion is formed to be small with respect to the rod portion, when the fastening member is touched, the influence of the hook portion on the tactile sensation (uncomfort) can be reduced. Therefore, the formed surface fastener of the present invention can stably obtain a good touch or feel of the skin as compared with a formed surface fastener having, for example, a conventional J-shaped or palm-like fastening member.

進而，於本發明之扣合元件中，如上所述，鉤部自桿部朝第2方向突出，並且於鉤部之下表面局部地形成較鉤部之上表面光滑且較硬地形成之壓縮面。又，於該鉤部中，鉤前端部形成為前端較窄之形狀。再者，本發明所述之前端較窄之形狀係指於俯視時以使鉤部之兩側緣朝鉤前端逐漸接近之方式而形成之形狀，即，使鉤部中之第1方向之尺寸朝鉤前端逐漸變小之形狀。因此，於使母型面扣結件之線圈扣合至本發明之成形面扣結件時，能夠順利地將本發明之扣合元件***至母型面扣結件之線圈間，並且能夠使線圈鉤在扣合元件之鉤部，從而穩定地扣合。 Further, in the fastening member of the present invention, as described above, the hook portion protrudes from the rod portion in the second direction, and the lower surface of the hook portion is locally formed into a compression which is smoother and harder than the upper surface of the hook portion. surface. Further, in the hook portion, the hook front end portion is formed in a shape in which the front end is narrow. Furthermore, the shape in which the front end is narrower in the present invention refers to a shape formed in such a manner that the side edges of the hook portion are gradually approached toward the front end of the hook in a plan view, that is, the size of the first direction in the hook portion. The shape that gradually becomes smaller toward the front end of the hook. Therefore, when the stitch of the female surface fastener is fastened to the forming surface fastening member of the present invention, the fastening member of the present invention can be smoothly inserted between the coils of the female surface fastening member, and The coil is hooked on the hook portion of the fastening member to be stably fastened.

並且，本發明之扣合元件與例如具有先前之蘑菇狀之扣合元件之成形面扣結件相比，能夠使鉤在鉤部之線圈難以自扣合元件脫離。因此，本發明之成形面扣結件能夠對母型面扣結件具有較高之剝離強度。 Further, the fastening element of the present invention can make it easier for the hook of the hook to be detached from the fastening element, as compared with, for example, a molded surface fastener having a conventional mushroom-shaped fastening element. Therefore, the forming surface fastener of the present invention can have a high peel strength to the female surface fastener.

即，本發明之成形面扣結件具有先前未有之特徵性形態，藉此成為兼具桿部不易折曲而獲得良好之肌膚觸感之優點、及對母型面扣結件具備較高之剝離強度之優點之新類型之成形面扣結件。因此，能夠藉由將本發明之成形面扣結件追加提供至先前之成形面扣結件，而使成形面扣結件之變化增多。其結果，易於更確切地應對各種類型之母型面扣結件(不織布)。 That is, the formed surface fastener of the present invention has a characteristic form which has not been previously formed, thereby achieving the advantage that the rod portion is not easily bent to obtain a good skin feel, and the female surface fastener member has a higher height. A new type of forming surface fastener for the advantage of peel strength. Therefore, it is possible to increase the variation of the forming surface fastening member by additionally providing the molding surface fastener of the present invention to the previous molding surface fastening member. As a result, it is easy to more accurately cope with various types of female-face fasteners (non-woven fabrics).

於此種本發明之成形面扣結件中，各扣合元件中之鉤部之上表面介隔階差而配置得較桿部之上表面高。又，鉤部具有如下形狀，即，當自第1方向(MD)觀察扣合元件時，鉤部之上表面(上部外表面)呈凸面狀，鉤部之下表面(下部外表面)呈非凸面狀。 In the forming surface fastener of the present invention, the upper surface of the hook portion of each fastening component is The step is arranged to be higher than the upper surface of the rod. Further, the hook portion has a shape in which the upper surface (upper outer surface) of the hook portion is convex when the fastening member is viewed from the first direction (MD), and the lower surface (lower outer surface) of the hook portion is non- Convex shape.

此處，鉤部之上表面呈凸面狀係指當自第1方向(MD)觀察鉤部時，鉤部中之自桿部側之基端部朝鉤前端部向下傾斜之鉤上表面具有看起來以朝上方***之方式凸狀地彎曲之連續之彎曲線狀之部分。又，鉤部之下表面呈非凸面狀係指鉤部中之自鉤基端部朝鉤前端部向上傾斜之鉤下表面(除鉤基端部及鉤前端部之下表面以外)並不具備當自第1方向(MD)觀察鉤部時以朝下方膨出之方式凸狀地彎曲之部分，而係由筆直地傾斜之直線狀之部分、及以朝內側略微凹陷之方式而彎曲之彎曲線狀之部分中之至少一者而形成。 Here, the convex surface of the hook portion means that when the hook portion is viewed from the first direction (MD), the hook end portion of the hook portion from the side of the rod portion is inclined downward toward the front end portion of the hook portion. It appears to be a continuous curved portion of the curve that is convexly curved in a manner that bulges upward. Further, the non-convex surface of the lower surface of the hook portion means that the lower surface of the hook portion of the hook portion which is inclined upward from the hook base end portion toward the front end portion of the hook (except for the hook base end portion and the lower surface of the hook front end portion) does not have When the hook portion is viewed from the first direction (MD), the portion that is convexly curved so as to bulge downward is formed by a straight portion that is inclined obliquely and a curved portion that is slightly recessed toward the inner side. Formed by at least one of the linear portions.

於具有此種形狀之扣合元件中，因鉤部之上表面呈凸面狀，故而能夠進一步減小鉤部對觸摸扣合元件時之觸感產生之影響，從而使成形面扣結件之肌膚觸感變得更加良好。又，因鉤部之下表面形成為非凸面狀，故而扣合元件之鉤部易於捕獲線圈，能夠使線圈更穩定地扣合至鉤部。進而，藉由使鉤部之上表面介隔階差而形成得較桿部之上表面高，扣合至扣合元件之線圈易於鉤在鉤部與桿部之間之階差，故而能夠使線圈不易自扣合元件脫離。其結果，本發明之成形面扣結件能夠對母型面扣結件具有更高之剝離強度。 In the fastening element having such a shape, since the upper surface of the hook portion is convex, the influence of the hook portion on the touch feeling when the fastening member is touched can be further reduced, so that the skin of the forming surface is buckled. The touch is getting better. Further, since the lower surface of the hook portion is formed in a non-convex shape, the hook portion of the engaging member is apt to catch the stitch, and the stitch can be more stably engaged to the hook portion. Further, by forming the upper surface of the hook portion to be higher than the upper surface of the rod portion, the loop that is fastened to the fastening member is liable to be hooked between the hook portion and the rod portion, so that the step can be made The coil is not easily detached from the fastening element. As a result, the formed face fastener of the present invention can have a higher peel strength to the female face fastener.

又，於本發明之成形面扣結件中，亦可不將鉤部之上表面配置得高於桿部之上表面，而使鉤部之上表面之一部分自桿部之上表面連續地形成。又，該情形時，鉤部亦具有如下形狀，即，當自第1方向(MD)觀察扣合元件時，鉤部之上表面(上部外表面)呈凸面狀，鉤部之下表面(下部外表面)呈非凸面狀。 Further, in the forming surface fastener of the present invention, the upper surface of the hook portion may not be disposed higher than the upper surface of the rod portion, and a part of the upper surface of the hook portion may be continuously formed from the upper surface of the rod portion. Further, in this case, the hook portion also has a shape in which the upper surface (upper outer surface) of the hook portion is convex when the fastening member is viewed from the first direction (MD), and the lower surface of the hook portion (lower portion) outer The surface) is non-convex.

於具有此種形狀之扣合元件中，因配置於鉤部之最高之位置之上表面自桿部之上表面連續地形成，故而能夠進一步減小鉤部對觸摸扣合元件時之觸感產生之影響，故而能夠使成形面扣結件之肌膚觸感變得更進一步良好。又，藉由使鉤部之下表面非凸面狀地形成，如上所述，能夠使扣合元件之鉤部易於捕獲線圈，從而使線圈更穩定地扣合至鉤部。 In the fastening element having such a shape, since the upper surface disposed at the highest position of the hook portion is continuously formed from the upper surface of the rod portion, the touch feeling of the hook portion to the touch fastening member can be further reduced. Therefore, the skin feel of the formed surface fastener can be further improved. Further, by forming the lower surface of the hook portion in a non-convex shape, as described above, the hook portion of the engaging member can be easily caught, and the stitch can be more stably engaged to the hook portion.

於如上所述般之2個形態之扣合元件之情形時，桿部之上端部之外表面(上表面)形成為球面。藉此，能夠有效地提高扣合元件之觸感。 In the case of the two types of fastening elements as described above, the outer surface (upper surface) of the upper end portion of the rod portion is formed into a spherical surface. Thereby, the tactile sensation of the fastening element can be effectively improved.

進而，於本發明之成形面扣結件中，亦可使扣合元件中之鉤部之上表面與桿部之上表面形成為單一之平坦面，並且鉤部之前端部朝下方傾斜配置。藉由使鉤部之上表面與桿部之上表面形成為單一之平坦面，能夠提高觸摸扣合元件時之觸感。又，藉由使鉤部之前端部朝下方傾斜，能夠使扣合元件之鉤部易於捕獲線圈，並且使鉤在鉤部之線圈不易自扣合元件脫離。 Further, in the forming surface fastener of the present invention, the upper surface of the hook portion and the upper surface of the rod portion in the fastening member may be formed as a single flat surface, and the front end portion of the hook portion may be inclined downward. By forming the upper surface of the hook portion and the upper surface of the rod portion into a single flat surface, the touch feeling when the fastening member is touched can be improved. Further, by tilting the front end portion of the hook portion downward, the hook portion of the engaging member can be easily caught, and the stitch of the hook portion at the hook portion is less likely to be detached from the fastening member.

該情形時，扣合元件具有配置於鉤部中之第1方向(MD)之兩側，連結鉤部之上端部與桿部之一對加強肋部。藉此，能夠有效地提高鉤部之強度。其結果，能夠增大成形面扣結件對母型面扣結件之剝離強度。 In this case, the fastening element has two sides disposed in the first direction (MD) of the hook portion, and the upper end portion of the hook portion and the one of the rod portions are reinforced with the rib portion. Thereby, the strength of the hook portion can be effectively improved. As a result, the peeling strength of the forming surface fastener to the female surface fastener can be increased.

於本發明之成形面扣結件中，當自第2方向(CD)觀察扣合元件之鉤部時，鉤部於鉤部之寬度方向(即，第1方向(MD))不對稱地形成。即，以鉤部之寬度方向上之中心位置為基準，配置於距該中心位置為第1方向之一側之部分與配置於距該中心位置為第1方向之另一側之部分具有互不相同之形狀。具有此種獨特之形狀之鉤部之扣合元件能夠將上述壓縮面局部地穩定地設置於鉤部之下表面，並且具備與先前不同之新穎之形態，故而針對各種不織布能夠擴大公型面扣結件之選擇之範圍。 In the forming surface fastener of the present invention, when the hook portion of the fastening member is viewed from the second direction (CD), the hook portion is asymmetrically formed in the width direction of the hook portion (that is, the first direction (MD)). . In other words, the portion disposed on one side from the center position in the first direction and the portion disposed on the other side in the first direction from the center position are not in contact with each other with respect to the center position in the width direction of the hook portion. The same shape. The fastening member having the hook portion having such a unique shape can locally stabilize the above-mentioned compression surface on the lower surface of the hook portion, and has a novel form different from the prior art, so that the needle The range of choices for various non-woven fabrics to expand the male profile fasteners.

另一方面，本發明之另一形態之成形面扣結件具有：平板狀之基材部，其沿第1方向及第2方向延伸，並且與第2方向相比，於第1方向呈長形；複數個扣合元件，其立設於基材部之上表面。又，各扣合元件具有：桿部，其等自基材部立起；及至少1個鉤部，其自桿部之上端部朝第2方向突出。進而，鉤部具有使第1方向之尺寸朝該鉤部之鉤前端遞減之前端較窄之形狀。又，當自第2方向(CD)觀察扣合元件之鉤部時，鉤部於鉤部之寬度方向(即，第1方向(MD))不對稱地形成。 On the other hand, the molding surface fastener according to another aspect of the present invention has a flat base portion that extends in the first direction and the second direction and that is longer in the first direction than the second direction. a plurality of fastening elements erected on the upper surface of the base material. Further, each of the fastening elements has a rod portion that rises from the base portion, and at least one hook portion that protrudes from the upper end portion of the rod portion in the second direction. Further, the hook portion has a shape in which the dimension in the first direction is tapered toward the front end of the hook portion of the hook portion. Further, when the hook portion of the fastening element is viewed from the second direction (CD), the hook portion is formed asymmetrically in the width direction of the hook portion (that is, in the first direction (MD)).

具有此種獨特之形狀之鉤部之本發明之扣合元件成為具有先前未有之特徵性形態之成形面扣結件。因此，能夠藉由將本發明之成形面扣結件追加提供至先前之成形面扣結件，而使成形面扣結件之變化增多。其結果，能夠擴大針對各種類型之母型面扣結件(不織布)之公型面扣結件之選擇之範圍。進而，藉由使扣合元件之鉤部具有如上所述之特徵性形狀，鉤部之下表面能夠局部地具有較鉤部之上表面光滑地形成之壓縮面。又，鉤部形成為朝鉤前端變細之前端較窄之形狀。其結果，本發明之成形面扣結件能夠兼具桿部不易折曲而獲得良好之肌膚觸感之優點、及對母型面扣結件具備較高之剝離強度之優點。 The fastening element of the present invention having such a uniquely shaped hook portion is a formed surface fastener having a previously uncharacteristically characteristic form. Therefore, it is possible to increase the variation of the forming surface fastening member by additionally providing the molding surface fastener of the present invention to the previous molding surface fastening member. As a result, it is possible to expand the range of selection of the male-face fasteners for various types of female-face fasteners (non-woven fabrics). Further, by making the hook portion of the fastening member have the characteristic shape as described above, the lower surface of the hook portion can locally have a compression surface which is formed smoother than the upper surface of the hook portion. Further, the hook portion is formed in a shape in which the end is narrower toward the front end of the hook. As a result, the formed surface fastener of the present invention can have both the advantage that the stem portion is not easily bent to obtain a good skin feel, and the peeling strength of the mother surface fastener member is high.

進而，於本發明之成形面扣結件中，於鉤部係於寬度方向(第1方向)不對稱地形成之情形時，鉤部之壓縮面中之第1方向之一端部(後端部)配置於該壓縮面中之較第1方向之另一端部(前端部)高之位置。進而，當自上方觀察扣合元件時，鉤部之前端部配置於相對於桿部之第1方向上之中心位置朝第1方向之一端部側(後方側)偏移之位置。如此，藉由使鉤部形成為扭曲之形狀，能夠於本發明之扣合元件中，將上述壓縮面進一步穩定地設置於鉤部之下表面。 Further, in the molding surface fastener according to the present invention, when the hook portion is formed asymmetrically in the width direction (first direction), one end of the first direction of the compression surface of the hook portion (rear end portion) And being disposed at a position higher than the other end portion (front end portion) of the first surface in the compression surface. Further, when the fastening element is viewed from above, the front end portion of the hook portion is disposed at a position shifted toward the one end side (rear side) in the first direction from the center position in the first direction with respect to the rod portion. Thus, by forming the hook portion into a twisted shape, the above-mentioned compression surface can be further stabilized in the fastening member of the present invention. Placed on the lower surface of the hook.

又，該情形時，當自第1方向(MD)觀察鉤部之情形時，鉤部之前端部中之曲率半徑設定為0.06mm以上且0.18mm以下之範圍內，較佳設定為0.12mm以上且0.15mm以下之範圍內。藉由以使前端部具有此種曲率半徑之方式形成鉤部，能夠使母型面扣結件之線圈易於鉤在扣合元件之鉤部。 Further, in this case, when the hook portion is viewed from the first direction (MD), the radius of curvature in the front end portion of the hook portion is set to be in the range of 0.06 mm or more and 0.18 mm or less, preferably set to 0.12 mm or more. And within the range of 0.15mm or less. By forming the hook portion such that the front end portion has such a radius of curvature, the coil of the female surface fastener can be easily hooked to the hook portion of the fastening member.

進而，於本發明之成形面扣結件中，相對於1個桿部配置有1個鉤部。該情形時，桿部具有自基材部立起並且朝鉤部之突出方向配置之鉤配設面。進而，鉤配設面具有自鉤部之下方朝基材部形成之單一之平坦面。該平坦面係與基材部之上表面正交並且與第2方向(CD)正交而形成。進而，鉤部係以自該平坦面上朝第2方向突出之方式而配置。 Further, in the forming surface fastener of the present invention, one hook portion is disposed with respect to one of the rod portions. In this case, the rod portion has a hook arrangement surface that rises from the base portion and is disposed toward the protruding direction of the hook portion. Further, the hook arrangement surface has a single flat surface formed from the lower side of the hook portion toward the base portion. The flat surface is formed to be orthogonal to the upper surface of the base portion and orthogonal to the second direction (CD). Further, the hook portion is disposed to protrude from the flat surface in the second direction.

藉由使扣合元件具有如上所述般之形狀，能夠使桿部穩定地具有特定之形狀。又，即便將母型面扣結件朝與鉤部之突設方向為相反側之方向拉伸，亦能夠利用桿部穩定地維持線圈扣合至扣合元件之狀態。因此，能夠增大剝離強度。 By having the fastening element have the shape as described above, the rod portion can be stably formed into a specific shape. Further, even if the female surface fastener is stretched in a direction opposite to the direction in which the hook portion protrudes, the rod portion can be stably maintained in a state in which the stitch is engaged to the fastening member. Therefore, the peel strength can be increased.

該情形時，當自第1方向(MD)觀察扣合元件時，桿部具有配置於相對於第2方向為鉤配設面之相反側之桿背面。該桿背面具有使桿部中之鉤配設面與桿背面之間之尺寸隨著遠離基材部之上表面而遞減之形狀。藉此，能夠穩定地確保桿部之強度。尤其是，即便於線圈扣合至扣合元件之狀態下使母型面扣結件朝第2方向(CD)上之與鉤部之突設方向為相反側之方向拉伸，桿部亦不易折曲(不易崩塌)，故而能夠增大對母型面扣結件之剪切強度。 In this case, when the fastening element is viewed from the first direction (MD), the rod portion has a rod rear surface disposed on the opposite side of the hook arrangement surface with respect to the second direction. The back surface of the rod has a shape in which the dimension between the hook arrangement surface in the rod portion and the back surface of the rod decreases as it goes away from the upper surface of the base portion. Thereby, the strength of the rod portion can be stably ensured. In particular, even when the coil is fastened to the fastening member, the female profile fastening member is stretched in the direction opposite to the protruding direction of the hook portion in the second direction (CD), and the stem portion is not easily The bending (not easy to collapse) can increase the shear strength of the female surface fastener.

又，該情形時，桿背面具有當自上述第1方向觀察扣合元件時凸狀地配置於桿部之上端部之上側曲面部、及凹狀地配置於上述桿部之下端部之下側曲面部。藉此，能夠使成形面扣結件具有良好之肌膚觸感，並且提高桿部之強度。 Moreover, in this case, the back surface of the rod has a convex shape when the fastening element is viewed from the first direction The upper curved surface portion of the upper end portion of the rod portion and the lower curved surface portion of the lower end portion of the rod portion are disposed in a concave shape. Thereby, the formed surface fastener can have a good skin feel and the strength of the stem portion can be improved.

進而，鉤部具有如下形狀，即，當自第1方向(MD)觀察扣合元件時，鉤部之上表面呈具備小於桿部之上側曲面部之曲率半徑之凸面狀。藉此，能夠維持成形面扣結件之良好之肌膚觸感，並且使母型面扣結件之線圈易於鉤在扣合元件。 Further, the hook portion has a shape in which the upper surface of the hook portion has a convex surface shape smaller than the radius of curvature of the upper curved surface portion of the rod portion when the fastening element is viewed from the first direction (MD). Thereby, it is possible to maintain a good skin feel of the forming surface fastener, and to make the loop of the female surface fastener easy to be hooked on the fastening member.

尤其是，於本發明之成形面扣結件中，桿部之第2方向(CD)上之最大尺寸設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。又，自鉤部之桿部突出之第2方向上之最大突出尺寸設定為0.01mm以上且0.5mm以下，較佳設定為0.05mm以上且0.1mm以下。只要為具有此種大小之扣合元件所形成之成形面扣結件，便能夠有效地增大各扣合元件之強度或對母型面扣結件之剝離強度。 In particular, in the forming surface fastener of the present invention, the maximum dimension in the second direction (CD) of the rod portion is set to be 0.1 mm or more and 1.5 mm or less, preferably 0.2 mm or more and 1.0 mm or less. Moreover, the maximum protrusion size in the second direction from which the rod portion of the hook portion protrudes is set to be 0.01 mm or more and 0.5 mm or less, and preferably set to 0.05 mm or more and 0.1 mm or less. As long as the forming surface fastening member formed by the fastening member having such a size can effectively increase the strength of each fastening member or the peeling strength of the female surface fastening member.

其次，製造如上所述之成形面扣結件之本發明之製造方法於成形面扣結件之成形步驟中係使用成形裝置，該成形裝置具有於外周面部形成有具備對應於扣合元件之形狀之複數個模腔(亦稱為模腔空間)之模輪。尤其是於本發明中，形成於模輪之模腔具有底切形狀，並且於模輪之模腔之模腔面配置有當將扣合元件拔出時能夠局部地按壓壓縮扣合元件之一部分(鉤部)之邊緣部。 Next, the manufacturing method of the present invention for producing the forming surface fastening member as described above uses a forming device in the forming step of the forming surface fastening member, the forming device having a shape formed on the outer peripheral surface corresponding to the fastening member a plurality of mold cavities (also referred to as cavity spaces). In particular, in the present invention, the cavity formed in the die wheel has an undercut shape, and the cavity surface of the cavity of the die wheel is disposed with a portion of the compression-fastening component that can be locally pressed when the fastening component is pulled out. The edge of the (hook).

此處，模腔具有底切形狀係指例如當對模輪之與機械方向(MD)(模輪之周向)正交之剖面進行觀察時，模腔於較交叉方向(CD)(與模輪之兩側方向平行之方向)之尺寸最小之最少正交尺寸部分更靠成形體之拔出方向(模輪之徑向)之裏側，具有交叉方向(CD)之尺寸大於最少正交尺寸部分之部分。藉由使模腔具有此種底切形狀，能夠使於模腔內成形之扣合元件無法以對應於模腔之原本之形狀脫模。因此，藉由將於模腔內成形之扣合元件以如下方式機械性地拉伸而強制地拔出，扣合元件之一部分(鉤部)被模腔面之邊緣部摩擦並且局部地按壓壓縮。 Here, the cavity having an undercut shape means, for example, when the profile of the die wheel orthogonal to the machine direction (MD) (the circumferential direction of the die wheel) is observed, the cavity is in a more intersecting direction (CD) (with a mode) The smallest orthogonal dimension of the smallest dimension of the direction of the sides of the wheel is further on the inner side of the direction in which the forming body is pulled out (the radial direction of the die wheel), and the dimension having the cross direction (CD) is larger than the minimum orthogonal size portion. Ministry Minute. By having the undercut shape of the cavity, the snap-fit member formed in the cavity can be prevented from being released in a shape corresponding to the original shape of the cavity. Therefore, a portion of the fastening member (hook portion) is frictionally rubbed by the edge portion of the cavity surface and is locally pressed and compressed by forcibly pulling out the fastening member formed in the cavity in such a manner as to be mechanically stretched as follows. .

於本發明之製造方法中，對設置有如上所述之底切形狀之模輪之外周面連續地吐出熔融之合成樹脂材料。藉此，於模輪之外周面上成形基材部，並且於模輪之模腔內成形具有自基材部立起之桿部、及自桿部之上端部朝與機械方向(MD)交叉之交叉方向(CD)突出之至少1個鉤部之扣合元件。 In the production method of the present invention, the molten synthetic resin material is continuously discharged to the outer peripheral surface of the die wheel provided with the undercut shape as described above. Thereby, the base material portion is formed on the outer circumferential surface of the die wheel, and the rod portion rising from the base portion is formed in the cavity of the die wheel, and the upper end portion from the rod portion is crossed to the machine direction (MD) A fastening element of at least one hook protruding in a cross direction (CD).

繼而，藉由對在模輪之外周面上成形之基材部進行拉伸等，將於模輪之模腔內硬化之扣合元件自模腔強制地拔出。此時，利用設置於模腔之邊緣部自鉤部之下方按壓壓縮並且摩擦扣合元件之鉤部，藉此於鉤部之下表面局部地形成較鉤部之上表面光滑之壓縮面。藉此，能夠有效率地並且穩定地製造具有較鉤部之上表面光滑之壓縮面形成於鉤部之下表面之扣合元件之本發明之成形面扣結件、或具有鉤部於鉤部之寬度方向(MD)不對稱地形成之扣合元件之本發明之成形面扣結件。 Then, by stretching the base material portion formed on the outer peripheral surface of the die wheel, the fastening member which is hardened in the cavity of the die wheel is forcibly pulled out from the cavity. At this time, the hook portion which is compressed and rubbed under the hook portion from the edge portion of the cavity is pressed, whereby the lower surface of the hook portion is locally formed with a compression surface which is smoother than the upper surface of the hook portion. Thereby, the forming surface fastening member of the present invention having the fastening surface formed on the lower surface of the hook portion having a smoother surface than the upper surface of the hook portion can be efficiently and stably manufactured, or has a hook portion at the hook portion.

In this case, the pickup roller has a pair of upper and lower nip rollers and a lower nip roller, and the forming surface fastener is sandwiched from the downstream side by the reverse nip roller and the lower nip roller. And the fastening component that is stretched into the cavity is formed. Thereby, the above-mentioned compression surface is partially formed on the lower surface of the hook portion of the fastening member. Moreover, at this time, since the hook portion is locally pressed and compressed, it may be inclined upward as it inclines upward with respect to the rod portion.

而且，自模輪之模腔拔出之扣合元件其後通過上下一對上側夾持輥及下側夾持輥間，藉此亦能夠利用藉由上側夾持輥之按壓使相對於桿部朝向斜上方之鉤部以朝下方彎折之方式變形。藉此，能夠更穩定地製造本發明之成形面扣結件。 Further, the fastening member pulled out from the cavity of the die wheel is passed between the upper and lower pair of upper clamping rollers and the lower clamping roller, whereby the pressing of the upper clamping roller can be utilized to make relative to the stem portion.

In this case, the rod back surface 25 has an upper curved surface portion 25a that is convex (or arc-shaped) at the upper end portion of the rod portion 21 and a lower curved surface portion 25b. The base portion 10 is disposed adjacent to the lower end portion of the rod portion 21 in a concave shape, and the inclined surface portion 25c is disposed between the upper curved surface portion 25a and the lower curved surface portion 25b.

進而，桿部21係以如下方式而形成，即，於本實施例1之扣合元件20之側視時，如圖5(或圖4)所示，使左右側緣間之MD上之尺寸隨著遠離基材部10之上表面而遞減。該情形時，桿部21於扣合元件20之側視時，具有：上側曲面部25a，其圓弧狀地配置於桿部21之上端部；下側曲面部25b，其與基材部10鄰接且凹狀地配置於桿部21之下端部；及傾斜面部25c，其配置於上側曲面部25a及下側曲面部25b間。 Further, the rod portion 21 is formed in such a manner that, in the side view of the fastening member 20 of the first embodiment, as shown in FIG. 5 (or FIG. 4), the size of the MD between the left and right side edges is made. It decreases as it goes away from the upper surface of the substrate portion 10. In this case, the lever portion 21 has an upper curved surface portion 25a which is disposed in an arc shape on the upper end portion of the rod portion 21 and a lower curved surface portion 25b and the base portion 10 when viewed from the side of the engaging element 20. The lower end portion of the rod portion 21 is disposed adjacent to the concave portion, and the inclined surface portion 25c is disposed between the upper curved surface portion 25a and the lower curved surface portion 25b.

藉由使本實施例1之桿部21具有如上所述之形態，即便例如朝本實施例1之成形面扣結件1強力地壓抵成為母型面扣結件之不織布，亦能夠穩定地具有不易發生桿部21彎折等之變形般之較高之強度。尤其是，藉由以如上方式形成桿部21之桿背面25，即便扣合元件20受到外力，桿部21亦不易以朝交叉方向(CD)之桿背面25側(左側)崩塌之方式而變形。藉此，能夠抑制因桿部21之變形而使鉤部31朝上方傾斜，故而能夠易於維持線圈鉤在鉤部31之狀態。 By providing the above-described rod portion 21 of the first embodiment in the above-described manner, it is possible to stably press the nonwoven fabric which is the female surface fastener member strongly against the molding surface fastener 1 of the first embodiment, for example. It has a high strength which is less likely to cause deformation such as bending of the stem portion 21. In particular, by forming the rod back surface 25 of the rod portion 21 as described above, even if the engaging member 20 receives an external force, the rod portion 21 is not easily deformed by collapse of the rod rear side 25 side (left side) in the cross direction (CD). . Thereby, it is possible to suppress the hook portion 31 from being inclined upward by the deformation of the rod portion 21, so that it is possible to easily maintain the state in which the coil is hooked on the hook portion 31.

本實施例1之鉤部31具有如下特徵性形態，即，朝向上方及左右側方之主外周面球面狀地形成，並且藉由在下述成形步驟中受到按壓及壓縮而較主外周面光滑地形成之壓縮面32配置於鉤部31之下表面。此處，表面光滑係指於表面凹凸更少，進而係指表面粗糙度更小。 The hook portion 31 of the first embodiment has the following characteristic features, that is, facing upward and left and right sides. The main outer peripheral surface is formed in a spherical shape, and the compression surface 32 formed to be smoothly formed from the main outer peripheral surface by being pressed and compressed in the forming step described below is disposed on the lower surface of the hook portion 31. Here, the smooth surface means less surface unevenness, and further means that the surface roughness is smaller.

又，鉤部31之下表面係指自鉤部31之前端跨及鉤部31中之成為與桿部21之連結部分之下端部而配置，並且朝下方或斜下方(即，朝基材部10)配置之鉤部31之外表面之部分。尤其是，於本實施例1之情形時，鉤部31之下表面配置於較鉤部31之前端之高度位置更靠下側。 Further, the lower surface of the hook portion 31 is disposed from the front end of the hook portion 31 and the lower end portion of the hook portion 31 which is the joint portion with the rod portion 21, and is disposed downward or obliquely downward (that is, toward the base portion). 10) A portion of the outer surface of the hook portion 31 that is disposed. In particular, in the case of the first embodiment, the lower surface of the hook portion 31 is disposed on the lower side than the height position of the front end of the hook portion 31.

若對本實施例1之鉤部31之形態更具體進行說明，則本實施例1之鉤部31具有如下形態，即，於圖4所示之扣合元件20之側視時，與桿部21之連結部分呈圓形，並且鉤部31之與CD正交之剖面之面積隨著遠離桿部21之平坦之桿部21而遞減。 When the shape of the hook portion 31 of the first embodiment is more specifically described, the hook portion 31 of the first embodiment has a configuration in which the hook portion 21 is viewed from the side of the fastening member 20 shown in FIG. The joint portion is circular, and the area of the cross section of the hook portion 31 orthogonal to the CD decreases as it goes away from the flat stem portion 21 of the stem portion 21.

換言之，鉤部31之外形具有隨著遠離桿部21而前端較窄之形狀。即，鉤部31係以使鉤寬度方向上之尺寸(前後方向之尺寸)隨著遠離桿部21而遞減之方式而形成。再者，鉤部31較佳為以使鉤上下方向上之尺寸(高度方向)亦隨著遠離桿部21而遞減之方式而形成。 In other words, the outer shape of the hook portion 31 has a shape in which the front end is narrower as it is away from the rod portion 21. In other words, the hook portion 31 is formed such that the dimension in the hook width direction (the dimension in the front-rear direction) decreases as moving away from the rod portion 21. Further, it is preferable that the hook portion 31 is formed such that the dimension (height direction) in the vertical direction of the hook is also decreased as moving away from the rod portion 21.

該鉤部31之上表面形成為球狀(半球狀)。因此，圖3所示之前視時之鉤部31之上端緣之形狀、及圖4所示之側視時之鉤部31之上端緣之形狀均呈以***之方式凸形地彎曲之連續之圓弧狀(彎曲線狀)。該情形時，球狀地形成之鉤部31之上表面中之曲率半徑設定為小於桿部21之球形狀之上端部中之曲率半徑。藉此，於使線圈扣合至本實施例1之成形面扣結件1時，易於將扣合元件20之鉤部31插通至線圈內，故而能夠使線圈順利地扣合至扣合元件20。 The upper surface of the hook portion 31 is formed in a spherical shape (hemispherical shape). Therefore, the shape of the upper end edge of the hook portion 31 in the front view shown in FIG. 3 and the shape of the upper end edge of the hook portion 31 in the side view shown in FIG. 4 are continuously convexly curved in a bulging manner. Arc-shaped (curved linear). In this case, the radius of curvature in the upper surface of the spherically formed hook portion 31 is set to be smaller than the radius of curvature in the upper end portion of the spherical shape of the rod portion 21. Therefore, when the coil is fastened to the forming surface fastening member 1 of the first embodiment, the hook portion 31 of the fastening component 20 is easily inserted into the coil, so that the coil can be smoothly fastened to the fastening component. 20.

又，自圖4可知，該鉤部31之寬度尺寸(M方向)小於桿部21之寬度尺寸(M方向)，於鉤部31之寬度方向外側露出有平坦之鉤配設面24。即，桿部21自鉤部31朝寬度方向之外側延伸。藉此，於使線圈扣合至本實施例1之成形面扣結件1時，易於將扣合元件20之鉤部31插通至線圈內，並且能夠確保桿部21之強度。 Moreover, as can be seen from FIG. 4, the width dimension (M direction) of the hook portion 31 is smaller than the width of the stem portion 21. In the inch (M direction), a flat hook arrangement surface 24 is exposed on the outer side in the width direction of the hook portion 31. That is, the rod portion 21 extends from the hook portion 31 toward the outer side in the width direction. Thereby, when the stitch is fastened to the forming surface fastener 1 of the first embodiment, the hook portion 31 of the fastening member 20 is easily inserted into the coil, and the strength of the rod portion 21 can be ensured.

尤其是，於本實施例1中，當自突出方向側(右側)觀察鉤部31時(參照圖4)，鉤部31之上表面或上端緣中之曲率半徑設定為0.01mm以上且0.5mm以下，較佳設定為0.05mm以上且0.1mm以下。又，當自M方向觀察桿部21時(參照圖3)，或當自C方向觀察桿部21時(參照圖4或圖5)，桿部21之上表面或上端緣中之曲率半徑大於鉤部31之上表面中之曲率半徑，並且設定為0.01mm以上且0.5mm以下，較佳設定為0.05mm以上且0.1mm以下。 In particular, in the first embodiment, when the hook portion 31 is viewed from the protruding direction side (right side) (refer to FIG. 4), the radius of curvature in the upper surface or the upper end edge of the hook portion 31 is set to 0.01 mm or more and 0.5 mm. Hereinafter, it is preferably set to 0.05 mm or more and 0.1 mm or less. Further, when the rod portion 21 is viewed from the M direction (refer to FIG. 3), or when the rod portion 21 is viewed from the C direction (refer to FIG. 4 or FIG. 5), the radius of curvature in the upper surface or the upper end edge of the rod portion 21 is larger than The radius of curvature in the upper surface of the hook portion 31 is set to be 0.01 mm or more and 0.5 mm or less, preferably 0.05 mm or more and 0.1 mm or less.

進而，於本實施例1中，當自M方向觀察鉤部31時(尤其是，如圖7所示，自後方側放大觀察鉤部31時)，鉤部31之前端部33具有呈大致圓弧狀之形狀。該情形時，鉤部31之前端部33之外表面中之曲率半徑設定為0.06mm以上且0.18mm以下之範圍內，較佳設定為0.12mm以上且0.15mm以下之範圍內。 Further, in the first embodiment, when the hook portion 31 is viewed from the M direction (in particular, as shown in Fig. 7, when the hook portion 31 is enlarged from the rear side), the front end portion 33 of the hook portion 31 has a substantially circular shape. Arc shape. In this case, the radius of curvature in the outer surface of the front end portion 33 of the hook portion 31 is set to be in the range of 0.06 mm or more and 0.18 mm or less, preferably in the range of 0.12 mm or more and 0.15 mm or less.

又，如上所述，鉤部31之下表面具有凹面狀地形成之壓縮面32。因此，於圖3所示之扣合元件20之前視時，鉤部31之上端緣雖然如上所述呈凸形之圓弧狀，但鉤部31之下端緣呈朝內側略微凹狀地彎曲般之非凸面形狀之形態。如此，鉤部31之下端緣具有成為凹面狀之非凸面形狀，藉此與例如該下端緣為凸面形狀之情形時相比，能夠使線圈易於鉤在(易於扣合至)鉤部31。進而，易於穩定地維持線圈之扣合狀態。再者，於本實施例1中，鉤部31之下端緣亦可具有於扣合元件20之前視時藉由直線地傾斜而呈非凸面形狀之形態。 Further, as described above, the lower surface of the hook portion 31 has a compression surface 32 formed in a concave shape. Therefore, in the front view of the engaging member 20 shown in FIG. 3, the upper end edge of the hook portion 31 has a convex arc shape as described above, but the lower end edge of the hook portion 31 is slightly concavely curved toward the inner side. The shape of the non-convex shape. As described above, the lower end edge of the hook portion 31 has a non-convex shape that is concave, whereby the coil can be easily hooked (easily fastened) to the hook portion 31 as compared with the case where the lower end edge has a convex shape, for example. Further, it is easy to stably maintain the snap-fit state of the coil. Furthermore, in the first embodiment, the lower end edge of the hook portion 31 may also have a linear inclination when the fastening member 20 is viewed from the front. It is in the form of a non-convex shape.

該情形時，鉤部31之上表面雖然形成為非壓縮面，但因係轉印下述第1模腔56之模腔面(蝕刻面)而形成，故而形成為表面粗糙度相對較小之光滑之面。 In this case, although the upper surface of the hook portion 31 is formed as an uncompressed surface, it is formed by transferring the cavity surface (etched surface) of the first cavity 56 to be described later, so that the surface roughness is relatively small. Smooth surface.

配置於鉤部31之下表面之壓縮面32係藉由在下述成形步驟中受到按壓壓縮而發生塑性變形(應變)並且經摩擦而形成。因此，鉤部31之壓縮面32係未轉印有第1模腔56之模腔面之非轉印面，較鉤部31之上表面更光滑且光潤地形成。因此，鉤部31之壓縮面32較鉤部31之其他面更多地反射光，故而亦存在於壓縮面32局部地觀察到光澤之情況。 The compression surface 32 disposed on the lower surface of the hook portion 31 is plastically deformed (strained) by press compression in the forming step described below and is formed by friction. Therefore, the compression surface 32 of the hook portion 31 is a non-transfer surface on which the cavity surface of the first cavity 56 is not transferred, and is smoother and smoother than the upper surface of the hook portion 31. Therefore, since the compression surface 32 of the hook portion 31 reflects more light than the other surfaces of the hook portion 31, the surface of the compression surface 32 is partially observed to have gloss.

進而，鉤部31之光滑之壓縮面32係受到按壓壓縮而形成，故而認為較鉤部31之上表面局部地硬度變大。若對鉤部31之下表面配置較硬之壓縮面32，則於利用鉤部31捕獲(保持)母型面扣結件之線圈時，能夠抑制鉤部31之變形而穩定地維持線圈扣合至鉤部31之狀態。 Further, since the smooth compression surface 32 of the hook portion 31 is formed by compression and compression, it is considered that the surface hardness of the upper surface of the hook portion 31 is locally increased. When the hard surface 32 is placed on the lower surface of the hook portion 31, when the hook portion 31 captures (holds) the stitch of the female surface fastener, the deformation of the hook portion 31 can be suppressed and the coil fastening can be stably maintained. The state to the hook portion 31.

進而，於本實施例1之扣合元件20中，桿部21具有如上所述般於前後方向(桿部21之寬度方向)對稱之形狀，但鉤部31具有於前後方向(鉤部31之寬度方向)不對稱之形狀。 Further, in the fastening element 20 of the first embodiment, the rod portion 21 has a shape that is symmetrical in the front-rear direction (the width direction of the rod portion 21) as described above, but the hook portion 31 has the front-rear direction (the hook portion 31) Width direction) Asymmetrical shape.

即，無論於圖4所示之扣合元件20之側視時，抑或是於圖6所示之扣合元件20之俯視時，鉤部31均形成為以前後方向(MD)之中心位置為基準配置於前方之前半部及配置於後方之後半部相互不對稱之不同形態。 That is, whether in the side view of the fastening member 20 shown in FIG. 4 or in the plan view of the fastening member 20 shown in FIG. 6, the hook portion 31 is formed in the center position of the front and rear direction (MD). The reference is arranged in a different form in which the front half portion and the rear half portion are asymmetrical to each other.

尤其是，因於本實施例1之鉤部31之下表面設置有上述壓縮面32，故而鉤部31之下半部具有扭曲般之形態。因此，鉤部31中之壓縮面32之後端部以例如於圖3所示之扣合元件20之前視時隱藏而看不見之方式，配置於較該壓縮面32之前端部上方高之位置(遠離基材部10之位置)。 In particular, since the lower surface of the hook portion 31 of the first embodiment is provided with the above-described compression surface 32, the lower half of the hook portion 31 has a twisted shape. Therefore, the rear end portion of the compression surface 32 in the hook portion 31 is disposed at a position higher than the front end portion of the compression surface 32 (for example, the fastening member 20 shown in FIG. Keep away from the position of the substrate portion 10).

於本實施例1中，如圖6所示，鉤部31中之最遠離桿部21之平坦之鉤配設面24之鉤前端部配置於較鉤部31之前後方向(MD)之中心位置更靠後方。該情形時，鉤部31之鉤前端部具有當自C方向之鉤突出側(右側)觀察扣合元件20時夾於鉤部31之上表面與壓縮面32而形成之鉤前端面34。該鉤前端面34介隔稜線與鉤部31之上表面及壓縮面32劃分開。 In the first embodiment, as shown in FIG. 6, the hook front end portion of the flat hook arrangement surface 24 of the hook portion 31 which is farthest from the rod portion 21 is disposed at the center position of the front and rear direction (MD) of the hook portion 31. More rearward. In this case, the hook front end portion of the hook portion 31 has a hook front end surface 34 formed by sandwiching the upper surface of the hook portion 31 and the compression surface 32 when the fastening member 20 is viewed from the hook side (right side) in the C direction. The hook front end surface 34 is separated from the upper surface of the hook portion 31 and the compression surface 32 by a ridge line.

又，於本實施例1之扣合元件20中，如圖2~圖5所示，於鉤部31之上表面與桿部21之上表面之間設置有階差(階差部)26。藉由該階差26，鉤部31之與桿部21連結之側之基端部22之上表面之高度位置(上下方向上之位置)配置得較桿部21之上表面高，鉤部31之一部分突出至較桿部21更靠上方而形成。 Further, in the engaging element 20 of the first embodiment, as shown in FIGS. 2 to 5, a step (step portion) 26 is provided between the upper surface of the hook portion 31 and the upper surface of the rod portion 21. By the step 26, the height position (the position in the up-and-down direction) of the upper surface of the base end portion 22 on the side where the hook portion 21 is coupled to the rod portion 21 is disposed higher than the upper surface of the rod portion 21, and the hook portion 31 is provided. A part of it protrudes to be formed above the rod portion 21.

又，於本實施例1中，扣合元件20之具體大小係以如下方式而設定。 Further, in the first embodiment, the specific size of the fastening member 20 is set as follows.

例如針對上下方向，扣合元件20中之距基材部10之上表面之最大高度尺寸H1設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。該情形時，桿部21中之距基材部10之上表面之最大高度尺寸H2設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。又，形成於鉤部31之上表面與桿部21之上表面之間之階差26之高度尺寸H3設定為0.01mm以上且0.3mm以下。進而，鉤部31之前端部中之距基材部10之上表面之上下方向之高度尺寸H4低於桿部21之上端中之高度位置，並且設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。 For example, in the vertical direction, the maximum height H1 from the upper surface of the base member 10 in the fastening member 20 is set to be 0.1 mm or more and 1.5 mm or less, and preferably 0.2 mm or more and 1.0 mm or less. In this case, the maximum height H2 of the upper surface of the base portion 10 in the rod portion 21 is set to be 0.1 mm or more and 1.5 mm or less, and preferably 0.2 mm or more and 1.0 mm or less. Further, the height dimension H3 of the step 26 formed between the upper surface of the hook portion 31 and the upper surface of the rod portion 21 is set to be 0.01 mm or more and 0.3 mm or less. Further, the height H4 of the upper end portion of the hook portion 31 from the upper surface of the upper surface of the base portion 10 is lower than the height position of the upper end of the rod portion 21, and is set to be 0.1 mm or more and 1.5 mm or less. It is set to 0.2 mm or more and 1.0 mm or less.

針對M方向(扣合元件20之寬度方向)，桿部21中之M方向之最大尺寸(即，桿部21之基端部22中之M方向之尺寸)L1設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。又，鉤部31中之M方向之最大尺寸L2設定為0.01mm以上且1.0mm以下，較佳設定為0.05mm以上且0.5mm以下。 The maximum dimension of the M direction in the rod portion 21 (that is, the dimension of the M direction in the base end portion 22 of the rod portion 21) L1 is set to be 0.1 mm or more and 1.5 mm in the M direction (the width direction of the fastening member 20). Hereinafter, it is preferably set to 0.2 mm or more and 1.0 mm or less. Also, the M direction in the hook portion 31 The maximum dimension L2 is set to 0.01 mm or more and 1.0 mm or less, and is preferably set to 0.05 mm or more and 0.5 mm or less.

針對C方向，桿部21中之C方向之最大尺寸(即，桿部21之基端部22中之C方向之尺寸)W1設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。進而，鉤部31中之C方向之最大尺寸(即，自鉤部31之前端至桿部21之鉤配設面24之C方向之尺寸)W2設定為0.01mm以上且1.0mm以下，較佳設定為0.05mm以上且0.5mm以下。 In the C direction, the maximum dimension in the C direction of the rod portion 21 (that is, the dimension in the C direction in the base end portion 22 of the rod portion 21) W1 is set to be 0.1 mm or more and 1.5 mm or less, preferably 0.2 mm or more. And less than 1.0mm. Further, the maximum dimension of the hook portion 31 in the C direction (that is, the dimension from the front end of the hook portion 31 to the C direction of the hook arrangement surface 24 of the stem portion 21) W2 is set to 0.01 mm or more and 1.0 mm or less, preferably. It is set to 0.05 mm or more and 0.5 mm or less.

進而，桿部21之上述傾斜面部25c之相對於上下方向之傾斜角度設定為5°以上且20°以下。又，如圖3所示，鉤部31中之上述C方向之最大尺寸W2較佳設定為鉤部31之下端與桿部21之鉤配設面24之間之和C方向平行之線段之尺寸(鉤部31之下端位置中之桿部21之C方向之尺寸)W3之一半以下。換言之，尺寸W3較佳設定為最大尺寸W2之2倍之大小以上。藉由使尺寸W2及尺寸W3具有此種關係，當以下述方式使扣合元件20成形時，能夠自球狀地形成於第1板55a之底切(undercut)形狀之第1模腔56，使具有如上所述般之壓縮面32之鉤部31一面變形一面成形。又，能夠製作鉤部31具備較小之鉤頭部，並且桿部21之強度較高之成形面扣結件1。進而，該情形時，如圖4所示，鉤部31中之上述M方向之最大尺寸L2較佳設定為鉤部31之下端位置中之桿部21之M方向之尺寸L3之一半以下。換言之，尺寸L3較佳設定為最大尺寸L2之2倍之大小以上。藉此，能夠成形具有壓縮面32之鉤部31，並且適當地確保桿部21之強度。 Further, the inclination angle of the inclined surface portion 25c of the rod portion 21 with respect to the vertical direction is set to 5 or more and 20 or less. Further, as shown in FIG. 3, the maximum dimension W2 of the C direction in the hook portion 31 is preferably set to a size of a line segment parallel to the C direction between the lower end of the hook portion 31 and the hook arrangement surface 24 of the rod portion 21. (the size of the rod portion 21 in the C direction in the lower end position of the hook portion 31) W3 is one-half or less. In other words, the size W3 is preferably set to be twice or more the maximum size W2. When the size W2 and the size W3 have such a relationship, when the fastening element 20 is formed as follows, the first cavity 56 of the undercut shape of the first plate 55a can be formed in a spherical shape. The hook portion 31 having the compression surface 32 as described above is deformed while being deformed. Further, it is possible to produce the molded surface fastener 1 in which the hook portion 31 has a small hook portion and the rod portion 21 has a high strength. Further, in this case, as shown in FIG. 4, the maximum dimension L2 of the M direction in the hook portion 31 is preferably set to be one-half or less of the dimension L3 of the rod portion 21 in the lower end position of the hook portion 31. In other words, the size L3 is preferably set to be twice or more the maximum size L2. Thereby, the hook portion 31 having the compression surface 32 can be formed, and the strength of the rod portion 21 can be appropriately ensured.

再者，於本實施例1之成形面扣結件1中，圖1~圖6所示之上述複數個扣合元件20立設於基材部10。然而，於本發明中，亦可不使立設於基材部10之所有扣合元件20具有相同形狀。 Further, in the molded surface fastener 1 of the first embodiment, the plurality of fastening elements 20 shown in FIGS. 1 to 6 are erected on the base portion 10. However, in the present invention, all of the fastening elements 20 that are erected on the base portion 10 may not have the same shape.

例如，本實施例1中之扣合元件20之大小一個一個非常小，故而亦存在難以使所有扣合元件20均為相同形狀之情況。又，即便於使用如下所述之成形裝置51進行成形面扣結件1之製造時，自相同形狀之成形模腔成形扣合元件20，亦存在因各種因素疊加而使扣合元件20之形狀(尤其是鉤部31之形狀)與其他扣合元件20不同之情況。 For example, the size of the fastening elements 20 in the first embodiment is very small, so that it is difficult to make all of the fastening elements 20 have the same shape. Further, even when the molding surface fastener 1 is manufactured by using the molding apparatus 51 as described below, the shape of the fastening member 20 is superposed by various factors from the molding cavity forming member 20 of the same shape. (In particular, the shape of the hook portion 31) is different from the other fastening elements 20.

因此，於本發明中，只要使立設於基材部之所有扣合元件中之一部分扣合元件為具備本發明之特徵之扣合元件即可。該情形時，具備本發明之特徵之扣合元件只要以立設於基材部之所有扣合元件之個數之10%以上之比率，較佳為25%以上之比率，特佳為50%以上之比率形成即可。關於此種具備本發明之特徵之扣合元件之比率，針對下述實施例2及3之成形面扣結件2、3亦相同。 Therefore, in the present invention, any one of the fastening members of all the fastening elements that are erected on the base portion may be a fastening member having the features of the present invention. In this case, the fastening element having the feature of the present invention is preferably a ratio of 10% or more, preferably 25% or more, particularly preferably 50%, of the number of all the fastening elements standing on the base portion. The above ratio can be formed. The ratio of the fastening elements having the features of the present invention is the same for the molding surface fasteners 2 and 3 of the following embodiments 2 and 3.

其次，對使用圖8所示之製造裝置50製造如上所述之本實施例1之成形面扣結件1之方法進行說明。 Next, a method of manufacturing the forming surface fastener 1 of the first embodiment described above using the manufacturing apparatus 50 shown in Fig. 8 will be described.

該成形面扣結件1之製造裝置50具有：成形裝置51，其進行成形面扣結件1(下述臨時成形面扣結件)之成形；及拾取輥54，其將所成形之成形面扣結件1自成形裝置51剝離，並且使扣合元件20之一部分變形。 The manufacturing apparatus 50 of the forming surface fastening member 1 has a forming device 51 that performs forming of a forming surface fastening member 1 (the following temporary forming surface fastening member), and a pickup roller 54 that forms a formed forming surface The fastening member 1 is peeled off from the forming device 51 and partially deforms one of the fastening members 20.

再者，藉由圖8之成形裝置51而成形之成形面扣結件係具有對鉤部實施按壓壓縮前之扣合元件之成形面扣結件。因此，利用成形裝置51成形且自模輪52剝離前之狀態之成形面扣結件與圖1所示之成形面扣結件1之形狀略有不同。換言之，對模輪52之下述模腔(即，第1模腔56、第2模腔57、及輔助模腔58)填充合成樹脂而形成並且自模輪52剝離前之狀態之扣合元件與圖1所示之扣合元件20之形狀略有不同。因此，亦可將自模輪52剝離前之成形面扣結件及扣合元件分別稱為臨時成形面扣結件及臨時扣合元件。再者，以下，為了防止發生說明之冗長或誤解，亦將「臨時成形面扣結件」及「臨時扣合元件」簡稱為「成形面扣結件1」及「扣合元件20」。 Further, the forming surface fastening member formed by the molding device 51 of Fig. 8 has a forming surface fastening member that performs a pressing member before pressing and compressing the hook portion. Therefore, the forming surface fastening member which is formed by the forming device 51 and is in a state before being peeled off from the die wheel 52 is slightly different from the shape of the forming surface fastening member 1 shown in Fig. 1. In other words, the fastening member in the state in which the following cavities of the die wheel 52 (i.e., the first cavity 56, the second cavity 57, and the auxiliary cavity 58) are filled with synthetic resin and peeled off from the die wheel 52 The shape of the fastening element 20 shown in Figure 1 is slightly different. Therefore, the forming surface fastening member and the fastening member before the mold wheel 52 is peeled off may also be referred to as a temporary forming surface fastening member and a temporary fastening. element. In addition, in the following, in order to prevent the lengthy or misunderstanding of the description, the "temporary forming surface fastener" and the "temporary fastening component" are simply referred to as "forming surface fastener 1" and "fastening component 20".

圖8所示之成形裝置51具有：模輪52，其朝一方向(於圖式中為逆時針方向)驅動旋轉；及擠出噴嘴53，其與模輪52之周面相對向而配置，連續地擠出熔融之合成樹脂材料。 The molding apparatus 51 shown in Fig. 8 has a die wheel 52 that is driven to rotate in one direction (counterclockwise in the drawing), and an extrusion nozzle 53 that is disposed opposite to the circumferential surface of the die wheel 52, continuous. The molten synthetic resin material is extruded.

於配置於成形裝置51之模輪52之外周面部，形成有為了使成形面扣結件1之扣合元件20成形而具備特定之形狀之複數個模腔。如圖9所示，該模輪52藉由使具有所需之厚度之複數個圓盤狀(或圓環狀)之金屬板55沿模輪52之旋轉軸方向重疊積層而形成為圓柱狀。又，各金屬板55具有：第1積層面，其與旋轉軸方向正交，並且形成旋轉軸方向之一側(圖9中為裏側)之面；及第2積層面，其與旋轉軸方向正交，並且形成旋轉軸方向之另一側(圖9中為近前側)之面。 A plurality of cavities having a specific shape for forming the engaging element 20 of the forming surface fastener 1 are formed on the outer peripheral surface of the die wheel 52 disposed on the molding apparatus 51. As shown in FIG. 9, the die wheel 52 is formed in a cylindrical shape by laminating a plurality of disk-shaped (or annular) metal plates 55 having a desired thickness in the direction of the rotation axis of the die wheel 52. Further, each of the metal plates 55 has a first buildup layer which is orthogonal to the direction of the rotation axis and which forms a surface on one side in the direction of the rotation axis (the back side in FIG. 9); and a second buildup layer which is oriented in the direction of the rotation axis It is orthogonal and forms the face of the other side of the rotation axis direction (the front side in FIG. 9).

如圖10所示，模輪52之金屬板55具有：第1板55a，其形成有使扣合元件20之鉤部31成形之第1模腔56；第2板55b，其形成有使扣合元件20之桿部21成形之第2模腔57；及複數個第3板55c，其等作為間隔件而配置。該等第1板55a~第3板55c沿旋轉軸方向逐片依序積層。 As shown in Fig. 10, the metal plate 55 of the die wheel 52 has a first plate 55a formed with a first cavity 56 for forming the hook portion 31 of the fastening member 20, and a second plate 55b formed with a buckle. The second cavity 57 in which the rod portion 21 of the component 20 is formed; and a plurality of third plates 55c are disposed as spacers. The first to fifth plates 55a to 55c are sequentially layered one by one in the direction of the rotation axis.

使鉤部31成形之第1板55a具有：第1模腔56，其為了使鉤部31成形而半球形地凹設於第1板55a之第1積層面；及輔助模腔58，其為了使桿部21之基端部22之一部分成形而形成。第1模腔56配置於自第1板55a之外周面朝第1板55a之徑向之內側以對應於圖1等所示之鉤部31與基材部10之間之間隔之距離而相隔之位置。即，第1模腔56並未開口於第1板55a之外周面。 The first plate 55a for molding the hook portion 31 has a first cavity 56 which is semi-spherically recessed in the first layer of the first plate 55a for molding the hook portion 31, and an auxiliary cavity 58 for A portion of the base end portion 22 of the rod portion 21 is formed to be formed. The first cavity 56 is disposed on the inner side of the outer surface of the first plate 55a from the outer peripheral surface of the first plate 55a so as to be spaced apart from the distance between the hook portion 31 and the base portion 10 shown in Fig. 1 and the like. The location. In other words, the first cavity 56 is not opened to the outer circumferential surface of the first plate 55a.

該半球形之第1模腔56之曲率半徑設定為圖1等所示之鉤部31之上表面中之曲率半徑之大小。因此，本實施例1之第1模腔56之曲率半徑設定為0.01mm以上且0.5mm以下，較佳設定為0.05mm以上且0.1mm以下之較小之大小。又，開口於第1板55a之第1積層面之第1模腔56形成扣合元件20之鉤部31之上表面與桿部21之上表面之間之階差26。即，第1模腔56之開口於第1積層面之徑向之最內側之位置係以配置於較第2板55b中之第2模腔57之開口於第2積層面之徑向之最內側之位置更靠徑向之內側之方式而形成。因此，於第1板55a與第2板55b之間形成有使第2板55b之第2積層面露出於第1模腔56之階差59。 The radius of curvature of the hemispherical first cavity 56 is set to the upper surface of the hook portion 31 shown in FIG. The radius of curvature in the face. Therefore, the radius of curvature of the first cavity 56 of the first embodiment is set to be 0.01 mm or more and 0.5 mm or less, and preferably set to a smaller size of 0.05 mm or more and 0.1 mm or less. Further, the first cavity 56 opened to the first layer of the first plate 55a forms a step 26 between the upper surface of the hook portion 31 of the engaging member 20 and the upper surface of the rod portion 21. In other words, the opening of the first cavity 56 is located at the innermost side in the radial direction of the first layer, and the opening of the second cavity 57 disposed in the second plate 55b is the radial direction of the second layer. The position of the inner side is formed further by the inner side of the radial direction. Therefore, a step 59 in which the second layer of the second plate 55b is exposed to the first cavity 56 is formed between the first plate 55a and the second plate 55b.

又，第1板55a之輔助模腔58凹設於第1板55a之第1積層面，並且開口於第1板55a之外周面而形成。該情形時，藉由配置於第1板55a之第1模腔56與輔助模腔58之間之平坦之第1積層面，形成扣合元件20之桿部21之鉤配設面24。 Further, the auxiliary cavity 58 of the first plate 55a is recessed in the first buildup layer of the first plate 55a, and is formed to open on the outer peripheral surface of the first plate 55a. In this case, the hook arrangement surface 24 of the rod portion 21 of the engaging element 20 is formed by the flat first layer formed between the first cavity 56 of the first plate 55a and the auxiliary cavity 58.

此種第1板55a之較小之第1模腔56與輔助模腔58係藉由對第1板55a之第1積層面進行半蝕刻加工而形成。藉由使用此種半蝕刻加工，能夠使第1模腔56及輔助模腔58形成為特定之形狀。進而，第1模腔56及輔助模腔58之各模腔面由光滑之曲面狀之蝕刻面形成。藉此，能夠使所成形之鉤部31之未受到下述按壓壓縮之外表面(尤其是，鉤部31之上表面)或桿部21之基端部22之一部分形成為表面粗糙度相對較小之光滑之面。 The smaller first cavity 56 and the auxiliary cavity 58 of the first plate 55a are formed by half etching the first layer of the first plate 55a. By using such a half etching process, the first cavity 56 and the auxiliary cavity 58 can be formed into a specific shape. Further, each of the cavity faces of the first cavity 56 and the auxiliary cavity 58 is formed by a smooth curved surface. Thereby, the surface of the formed hook portion 31 which is not subjected to the following compression compression (especially, the upper surface of the hook portion 31) or the base end portion 22 of the rod portion 21 can be formed to have a relatively rough surface roughness. Small smooth face.

使桿部21成形之第2板55b於第2板55b之第2積層面具有以自第2板55b之外周面朝第2板55b之徑向之內側延伸之方式連續地凹設之第2模腔57。該第2模腔57與第1板55a之輔助模腔58一併形成扣合元件20之桿部21。因此，第2模腔57以具有桿部21之除利用輔助模腔58成形之部分以外之形狀之方式，使第2模腔57中之周向之尺寸自第1板55a之外周面朝徑向之內側遞減而形成。 The second plate 55b which is formed by the rod portion 21 has a second layer which is continuously recessed from the outer circumferential surface of the second plate 55b toward the inner side in the radial direction of the second plate 55b. Cavity 57. The second cavity 57 forms the stem portion 21 of the fastening member 20 together with the auxiliary cavity 58 of the first plate 55a. Therefore, the second cavity 57 has the shape of the stem portion 21 other than the portion formed by the auxiliary cavity 58 so that the circumferential dimension of the second cavity 57 is radially outward from the outer peripheral surface of the first plate 55a. The inside is formed by decreasing.

又，本實施例1之第2模腔57係以使配置於徑向之最內側之部分之模腔面呈球面之方式而形成。該第2板55b之第2模腔57係藉由對第2板55b之第2積層面進行半蝕刻加工而形成。藉此，第2模腔57之模腔面由光滑之曲面狀之蝕刻面形成。因此，能夠使所成形之桿部21之外表面與鉤部31之上表面同樣地，形成為表面粗糙度相對較小之光滑之面。 Further, the second cavity 57 of the first embodiment is formed such that the cavity surface of the portion disposed on the innermost side in the radial direction is spherical. The second cavity 57 of the second plate 55b is formed by half etching the second layer of the second plate 55b. Thereby, the cavity surface of the second cavity 57 is formed by a smooth curved surface. Therefore, the outer surface of the formed rod portion 21 can be formed into a smooth surface having a relatively small surface roughness similarly to the upper surface of the hook portion 31.

本實施例1之第3板55c由未形成有模腔之圓盤狀之板形成。又，該第3板55c之厚度(旋轉軸方向之尺寸)係根據設置於成形面扣結件1之扣合元件20之交叉方向(CD)上之形成間距而設定。 The third plate 55c of the first embodiment is formed of a disk-shaped plate in which a cavity is not formed. Moreover, the thickness (the dimension in the direction of the rotation axis) of the third plate 55c is set in accordance with the formation pitch in the intersecting direction (CD) of the fastening elements 20 provided on the forming surface fastener 1.

如上所述之第1板55a~第3板55c係以使第1板55a之第1積層面與第2板55b之第2積層面相對面，使第2板55b之第1積層面與第3板55c之第2積層面相對面，使第3板55c之第1積層面與第1板55a之第2積層面相對面之方式，依序反覆積層而固定。藉此，於第1板55a與第2板55b相互鄰接積層，並且第1板55a之第1模腔56及輔助模腔58與第2板55b之第2模腔57連通之狀態下形成本實施例1之模輪52。 The first plate 55a to the third plate 55c as described above are such that the first layer of the first plate 55a faces the second layer of the second plate 55b, and the first layer and the third layer of the second plate 55b are formed. The second layer-facing surface of the plate 55c is fixed so as to overlap the first layer of the third plate 55c and the second layer of the first plate 55a. Thereby, the first plate 55a and the second plate 55b are laminated adjacent to each other, and the first cavity 56 and the auxiliary cavity 58 of the first plate 55a are in communication with the second cavity 57 of the second plate 55b. The die wheel 52 of the embodiment 1.

針對此種本實施例1之模輪52，圖10係表示將模輪52於桿部21之機械方向(MD)上之中心位置沿旋轉軸方向切斷之剖視圖。於該圖10之剖視圖中，針對使扣合元件20成形之模腔整體，將第1模腔56之與徑向外側鄰接之位置處之第1板55a之第1積層面與第2板55b之第2模腔57之模腔面之間之旋轉軸方向(CD)上之尺寸設為D1。又，將第1模腔56之距第1積層面最深之位置之模腔面與第2板55b之第2模腔57之模腔面之間之旋轉軸方向(CD)上之尺寸設為D2。 With respect to the mold wheel 52 of the first embodiment, FIG. 10 is a cross-sectional view showing the center position of the mold wheel 52 in the machine direction (MD) of the rod portion 21 taken along the direction of the rotation axis. In the cross-sectional view of Fig. 10, the first layer of the first plate 55a and the second plate 55b at the position adjacent to the radially outer side of the first cavity 56 are formed for the entire cavity in which the fastening element 20 is formed. The dimension in the direction of the rotation axis (CD) between the cavity faces of the second cavity 57 is set to D1. Further, the dimension in the direction of the rotation axis (CD) between the cavity surface of the first cavity 56 at the deepest position on the first accumulation level and the cavity surface of the second cavity 57 of the second plate 55b is set to D2.

該情形時，於本實施例1之模輪52之外周面部，使上述尺寸D1小於位於較該尺寸D1更靠徑向之內側之上述尺寸D2，形成有扣合元件20用成形模腔。藉此，第1板55a之第1模腔56於自模輪52之外周面朝內側相隔之位置形成為使下述臨時成形面扣結件無法以原本之形狀脫模之底切形狀。 In this case, in the outer peripheral surface of the die wheel 52 of the first embodiment, the above dimension D1 is made smaller than The above-described dimension D2 located on the inner side of the radial direction D1 is formed with a forming cavity for the engaging member 20. Thereby, the first cavity 56 of the first plate 55a is formed at a position spaced apart from the outer circumferential surface of the die wheel 52 so as to be in an undercut shape in which the following temporary molding surface fastener cannot be released in the original shape.

進而，於第1板55a，以使第1模腔56之模腔面與第1積層面大致正交之方式，以帶稜角之形狀形成有圓周狀之稜線部。該圓周狀之稜線部中之配置於徑向之外側之圓弧部分之稜線部係作為於自模輪52之模腔拔出扣合元件20時局部地按壓壓縮扣合元件20之鉤部31之下表面之邊緣部60而配置。 Further, in the first plate 55a, a circumferential ridge line portion is formed in an angular shape so that the cavity surface of the first cavity 56 is substantially perpendicular to the first buildup layer. The ridge portion of the circular arc portion disposed on the radially outer side of the circumferential ridge line portion serves to partially press the hook portion 31 of the compression fastening member 20 when the fastening member 20 is pulled out from the cavity of the mold wheel 52. The edge portion 60 of the lower surface is disposed.

又，於本實施例1之模輪52設置有使模輪52朝一方向旋轉之未圖示之旋轉驅動輥。進而，於本實施例1之模輪52，亦可於模輪52之內部設置使冷卻液流通之未圖示之冷卻套。藉此，能夠有效率地冷卻於模輪52之外周面部成形之成形面扣結件1。 Further, the die wheel 52 of the first embodiment is provided with a rotary drive roller (not shown) that rotates the die wheel 52 in one direction. Further, in the die wheel 52 of the first embodiment, a cooling jacket (not shown) through which the coolant flows can be provided inside the die wheel 52. Thereby, the forming surface fastener 1 formed on the outer peripheral surface of the die wheel 52 can be efficiently cooled.

圖8所示之拾取輥54具有將於模輪52之周面部成形之成形面扣結件1(臨時成形面扣結件)自上下夾持而拉伸之一對上側夾持輥54a及下側夾持輥54b。又，於上側夾持輥54a之成形面扣結件1所接觸之外周面部及下側夾持輥54b之成形面扣結件1所接觸之外周面部，設置有包含聚胺基甲酸酯彈性體等彈性體之未圖示之表面層。 The pickup roller 54 shown in Fig. 8 has a forming surface fastening member 1 (temporary molding surface fastening member) which is formed on the circumferential surface of the mold wheel 52, and is stretched from above and below to stretch one of the upper side nip rollers 54a and lower. Side clamping roller 54b. Moreover, the peripheral surface portion of the outer peripheral surface portion and the lower surface of the lower side nip roller 54b which is contacted by the forming surface fastening member 1 of the upper side nip roller 54a is provided with a polyurethane-containing elastic layer. A surface layer (not shown) of an elastomer such as a body.

上側夾持輥54a與下側夾持輥54b隔開特定之間隔而對向配置。該等上側夾持輥54a與下側夾持輥54b分別朝特定之方向以特定之速度旋轉，藉此能夠將成形面扣結件1一面自模輪52連續地剝離，一面順利地送出至下游側。 The upper nip roller 54a and the lower nip roller 54b are disposed to face each other at a predetermined interval. The upper nip roller 54a and the lower nip roller 54b are respectively rotated at a specific speed in a specific direction, whereby the molding surface fastener 1 can be continuously peeled off from the die wheel 52 while being smoothly sent downstream. side.

於使用如上所述之製造裝置50進行成形面扣結件1之製造之情形時，首先，自擠出噴嘴53朝模輪52之外周面連續地吐出熔融之合成樹脂材料。此時，模輪52朝一方向驅動旋轉。因此，藉由對模輪52之周面擠出熔融樹脂材料，對連續擠出噴嘴53與旋轉之模輪52之間之空間部連續地填充合成樹脂材料，並且亦對設置於模輪52之外周面部之各成形用模腔(空間部)內填充合成樹脂材料。 When the manufacturing of the forming surface fastener 1 is performed by using the manufacturing apparatus 50 as described above, first, the molten synthetic resin material is continuously discharged from the extrusion nozzle 53 toward the outer circumferential surface of the die wheel 52. material. At this time, the die wheel 52 is driven to rotate in one direction. Therefore, by extruding the molten resin material to the circumferential surface of the die wheel 52, the space between the continuous extrusion nozzle 53 and the rotating die wheel 52 is continuously filled with the synthetic resin material, and is also disposed on the die wheel 52. A molding resin material is filled in each molding cavity (space portion) of the outer peripheral surface.

此時，熔融之合成樹脂材料自模輪52之外周面流入至第1板55a之輔助模腔58與第2板55b之第2模腔57，進而，經由第2板55b之第2模腔57流入至第1板55a之第1模腔56。藉此，藉由合成樹脂材料填滿由第1模腔56、第2模腔57、及輔助模腔58形成之扣合元件成形用模腔之空間部分。 At this time, the molten synthetic resin material flows from the outer peripheral surface of the die wheel 52 to the auxiliary cavity 58 of the first plate 55a and the second cavity 57 of the second plate 55b, and further passes through the second cavity of the second plate 55b. 57 flows into the first cavity 56 of the first plate 55a. Thereby, the space portion of the cavity for forming the engaging element formed by the first cavity 56, the second cavity 57, and the auxiliary cavity 58 is filled with the synthetic resin material.

繼而，以如上方式填充至連續擠出噴嘴53與模輪52之間並且填充至模輪52之各模腔內之合成樹脂材料一面由朝一方向旋轉之模輪52之外周面擔載，一面冷卻至低於熔點之溫度。藉此，對應於設置於模輪52之模腔之形狀之複數個扣合元件(臨時扣合元件)成形為立設於在模輪52之外周面上成形之基材部10之成形面扣結件(臨時成形面扣結件)。即，此時成形之於模腔內填充有樹脂之狀態之扣合元件(臨時扣合元件)雖然省略了圖示，但具有上述桿部21、及自該桿部21朝C方向突出之半球形狀之鉤部(臨時鉤部)。又，該成形之半球形狀之鉤部(臨時鉤部)中之包含上表面及下表面之外表面由第1模腔56之模腔面形成。 Then, the synthetic resin material filled in the respective cavities between the continuous extrusion nozzle 53 and the die wheel 52 in the above manner and filled in the cavity of the die wheel 52 is supported by the outer peripheral surface of the die wheel 52 which is rotated in one direction, and is cooled. To a temperature below the melting point. Thereby, a plurality of fastening elements (temporary fastening elements) corresponding to the shape of the cavity provided in the die wheel 52 are formed into a forming face buckle which is erected on the outer peripheral surface of the die wheel 52. Knot (temporary forming surface fastening). In other words, the engaging member (temporary fastening member) which is formed in a state in which the resin is filled in the cavity is not shown, but has the above-described rod portion 21 and a hemisphere protruding from the rod portion 21 toward the C direction. The hook of the shape (temporary hook). Further, the outer surface including the upper surface and the lower surface of the formed hemispherical hook portion (temporary hook portion) is formed by the cavity surface of the first cavity 56.

於該模輪52之外周面部成形之成形面扣結件(臨時成形面扣結件)其後藉由上述拾取輥54自模輪52之外周面部連續地並且強制地(強行地)剝離。此時，於形成於模輪52之外周面部之模腔中，第1板55a之第1模腔56如上所述形成為底切形狀。 The forming surface fastener (temporary forming surface fastening member) formed on the outer peripheral surface of the die wheel 52 is continuously and forcibly (forced) peeled off from the outer peripheral surface of the die wheel 52 by the above-described pickup roller 54. At this time, in the cavity formed in the outer peripheral surface of the die wheel 52, the first cavity 56 of the first plate 55a is formed into an undercut shape as described above.

因此，如圖11所示，藉由利用拾取輥54拉伸成形面扣結件1，於模腔內成形之扣合元件(臨時扣合元件)之半球形狀之鉤部自該模腔拔出時，藉由形成於第1板55a之上述邊緣部60，自鉤部之下表面側按壓壓縮。此時，因模輪52沿機械方向旋轉，故而受到按壓之鉤部亦受到藉由第1板55a之邊緣部60朝機械方向扭曲般之外力。 Therefore, as shown in FIG. 11, by the drawing of the forming surface fastening member 1 by the pickup roller 54, the hemispherical hook portion of the fastening member (temporary fastening member) formed in the cavity is pulled out from the cavity. Borrow The edge portion 60 formed on the first plate 55a is pressed and compressed from the lower surface side of the hook portion. At this time, since the die wheel 52 rotates in the machine direction, the hook portion that is pressed is also subjected to a force that is twisted in the machine direction by the edge portion 60 of the first plate 55a.

尤其是，於本實施例1中，於第1板55a與第2板55b之間，如上所述，形成有使第2板55b之第2積層面露出於第1模腔56般之階差59。因此，能夠不易使臨時扣合元件之半球形狀之鉤部自第1板55a之第1模腔56進一步拔出。藉此，能夠藉由第1板55a之邊緣部60按壓及壓縮鉤部之下表面。 In particular, in the first embodiment, as described above, the step of exposing the second layer of the second plate 55b to the first cavity 56 is formed between the first plate 55a and the second plate 55b. 59. Therefore, it is possible to prevent the hook portion of the hemispherical shape of the temporary fastening element from being further pulled out from the first cavity 56 of the first plate 55a. Thereby, the lower surface of the hook portion can be pressed and compressed by the edge portion 60 of the first plate 55a.

於一面將臨時扣合元件拔出，一面藉由第1板55a之邊緣部60以某程度之範圍(體積)按壓及壓縮半球形狀之鉤部之後，扣合元件20之桿部21以朝桿背面25側傾倒之方式略微變形(彈性變形)，以使鉤部易於自第1模腔56拔出。又，同時，鉤部一面藉由第1板55a之邊緣部60進一步按壓並且摩擦鉤部之下表面，一面自第1板55a之第1模腔56拔出。如此，藉由第1板55a之邊緣部60按壓壓縮並且摩擦半球形狀之鉤部之下表面，藉此於鉤部31之下表面形成如上所述之光滑且較硬之壓縮面32。 After the temporary fastening element is pulled out on one side, and the hemispherical hook portion is pressed and compressed by the edge portion 60 of the first plate 55a to a certain extent (volume), the rod portion 21 of the engaging member 20 is oriented toward the rod. The manner in which the back side 25 is tilted is slightly deformed (elastically deformed) so that the hook portion is easily pulled out from the first cavity 56. At the same time, the hook portion is pulled out from the first cavity 56 of the first plate 55a while being further pressed by the edge portion 60 of the first plate 55a and rubbing the lower surface of the hook portion. Thus, the lower surface of the hemispherical hook portion is pressed and compressed by the edge portion 60 of the first plate 55a, whereby the smooth and hard compression surface 32 as described above is formed on the lower surface of the hook portion 31.

進而，當將鉤部自第1模腔56拔出時，鉤部一面自邊緣部60受到如上所述之扭曲之外力，一面由該邊緣部60按壓。因此，鉤部以自桿部21朝鉤前端向上傾斜之方式朝上方傾斜或彎曲地整體變形，並且變形為於M方向上不對稱之形狀。進而，於將鉤部自第1板55a之第1模腔56拔出之後，連續地拉伸扣合元件，藉此將扣合元件整體自模輪52之模腔拔出。 Further, when the hook portion is pulled out from the first cavity 56, the hook portion is pressed by the edge portion 60 while receiving a force other than the above-described deformation from the edge portion 60 as described above. Therefore, the hook portion is integrally deformed obliquely or curved upward from the rod portion 21 toward the front end of the hook, and is deformed into a shape asymmetrical in the M direction. Further, after the hook portion is pulled out from the first cavity 56 of the first plate 55a, the fastening member is continuously drawn, whereby the entire fastening member is pulled out from the cavity of the die wheel 52.

然後，自模輪52剝離且鉤部變形之成形面扣結件立即被導入至拾取輥54之相互以特定間隔相隔而配置之上側夾持輥54a與下側夾持輥54b之間，夾於該等上側夾持輥54a及下側夾持輥54b間。此時，如上所述自模輪52之模腔拔出且自桿部21朝上方變形之鉤部由上側夾持輥54a自上方按壓。藉此，能夠使以向上傾斜之方式變形之鉤部以朝向C方向之方式強制地(積極地)朝下方塑性變形。藉此，製造圖1所示之本實施例1之成形面扣結件1。 Then, the forming surface fastening member which is peeled off from the die wheel 52 and whose hook portion is deformed is immediately introduced between the upper side pinch roller 54a and the lower side pinch roller 54b by being introduced to the pickup roller 54 at a predetermined interval. Between the upper nip roller 54a and the lower nip roller 54b. At this time, the hook portion which is pulled out from the cavity of the die wheel 52 and deformed upward from the rod portion 21 as described above is pressed from above by the upper pinch roller 54a. Pressure. Thereby, the hook portion deformed in an upwardly inclined manner can be forcibly (positively) plastically deformed downward toward the C direction. Thereby, the forming surface fastener 1 of the first embodiment shown in Fig. 1 was produced.

其後，將通過拾取輥54之上側夾持輥54a及下側夾持輥54b間之於機械方向上長形之成形面扣結件1朝未圖示之切斷部搬送，利用該切斷部切斷成特定之長度而回收。或，以長形之成形面扣結件1之狀態卷狀地卷取至回收輥等而回收。 Then, the forming surface fastener 1 which is elongated in the machine direction between the upper side nip roller 54a and the lower side nip roller 54b of the pickup roller 54 is conveyed to a cutting portion (not shown), and the cutting is performed by the cutting portion. The part is cut to a specific length and recovered. Alternatively, it is taken up in a roll shape in the form of an elongated molded surface fastener 1 and collected in a recovery roll or the like.

以如上方式製造之本實施例1之成形面扣結件1具有：桿部21，其自基材部10較粗地立設；及微小之鉤部31，其自桿部21之上端部朝C方向突出。進而，當自C方向觀察扣合元件20之鉤部31時(參照圖4)，鉤部31於鉤部31之寬度方向(MD)不對稱地形成。形成有此種鉤部31之本實施例1之扣合元件20具有與先前之J字狀、棕櫚樹狀、及蘑菇狀完全不同之特徵性形態。而且，具有此種特徵性形態之扣合元件20之成形面扣結件1具有先前之成形面扣結件所無法獲得之如下特徵性性質。 The forming surface fastener 1 of the first embodiment manufactured in the above manner has a rod portion 21 which is erected from the base portion 10 and a minute hook portion 31 which faces from the upper end portion of the rod portion 21 toward The C direction is prominent. Further, when the hook portion 31 of the engaging element 20 is viewed from the C direction (see FIG. 4), the hook portion 31 is asymmetrically formed in the width direction (MD) of the hook portion 31. The fastening element 20 of the first embodiment in which the hook portion 31 is formed has a characteristic form completely different from the previous J-shape, palm tree shape, and mushroom shape. Moreover, the forming surface fastening member 1 of the fastening member 20 having such a characteristic form has the following characteristic properties which cannot be obtained by the previous forming surface fastening member.

若具體進行說明，則於本實施例1之成形面扣結件1中，扣合元件20之桿部21係較粗並且以使桿部21之上表面(頂端面)呈球面之方式而形成。因此，能夠提高桿部21之強度，並且能夠使扣合元件20之肌膚觸感變得良好。 Specifically, in the forming surface fastening member 1 of the first embodiment, the rod portion 21 of the fastening member 20 is thick and formed such that the upper surface (tip surface) of the rod portion 21 is spherical. . Therefore, the strength of the rod portion 21 can be improved, and the skin feel of the fastening member 20 can be improved.

如此，藉由使桿部21之強度較高，本實施例1之成形面扣結件1即便例如強力地壓抵至母型面扣結件而受到較大之按壓力，桿部21亦不易折曲，能夠穩定地保持扣合元件20之形狀。進而，藉此，能夠將本實施例1之成形面扣結件1對母型面扣結件壓入至更深之位置，換言之，能夠將成形面扣結件1之各扣合元件20較深地***至母型面扣結件之線圈之根部附近。其結果，本實施例1之成形面扣結件1更易於捕捉母型面扣結件之線圈，故而能夠順利地並且穩定地與母型面扣結件扣合。 Thus, by making the strength of the rod portion 21 high, the forming surface fastening member 1 of the first embodiment is subjected to a large pressing force even if it is strongly pressed against the female surface fastener member, for example, and the rod portion 21 is not easily used. The bending can stably maintain the shape of the fastening member 20. Further, by this, the forming surface fastener 1 of the first embodiment can be pressed into the deeper position of the female surface fastener, in other words, the fastening elements 20 of the forming surface fastening member 1 can be deeper. Inserted into the root of the coil of the female profile fastening member near. As a result, the forming surface fastener 1 of the first embodiment can more easily capture the stitch of the female surface fastener, and thus can be smoothly and stably engaged with the female surface fastener.

又，如此，藉由使桿部21之強度較高，能夠增大成形面扣結件1對母型面扣結件之剪切強度。此處，剪切強度係指於將母型面扣結件貼合至成形面扣結件1而使兩者扣合之狀態下，以使成形面扣結件1與母型面扣結件相對地於成形面扣結件1之長度方向或寬度方向上偏移之方式拉伸時之扣合強度。 Moreover, by making the strength of the rod portion 21 high, the shear strength of the forming surface fastener 1 to the female surface fastener can be increased. Here, the shear strength refers to a state in which the female surface fastener is attached to the forming surface fastening member 1 to fasten the two, so that the forming surface fastening member 1 and the female surface fastening member are The fastening strength at the time of stretching relative to the longitudinal direction or the width direction of the forming surface fastener 1 is relatively.

進而，於本實施例1之扣合元件20中，極小之鉤部31自桿部21之上端部朝C方向突出。進而，如上所述，扣合元件20之鉤部31之下表面局部地具有較鉤部31之上表面光滑地形成之壓縮面32。因此，當使母型面扣結件之線圈扣合至本實施例1之成形面扣結件1時，能夠將扣合元件20順利地***至母型面扣結件之線圈間，並且能夠使線圈穩定地扣合至扣合元件20之鉤部31。 Further, in the fastening element 20 of the first embodiment, the extremely small hook portion 31 protrudes from the upper end portion of the rod portion 21 in the C direction. Further, as described above, the lower surface of the hook portion 31 of the fastening member 20 partially has a compression surface 32 which is formed smoother than the upper surface of the hook portion 31. Therefore, when the stitch of the female surface fastener is fastened to the forming surface fastening member 1 of the first embodiment, the fastening member 20 can be smoothly inserted between the coils of the female surface fastening member, and The coil is stably fastened to the hook portion 31 of the fastening member 20.

進而，藉由使鉤部31之下表面具有較硬且光滑之壓縮面32，即便將線圈朝上方拉伸，鉤部31本身亦難以朝上變形。並且，因桿部21較粗且其強度較高，故而亦能夠有效地防止桿部21本身亦以使鉤部31朝上之方式而變形。此外，於本實施例1之成形面扣結件1中，鉤部31之上表面介隔階差26而設置得較桿部21之上表面高。藉此，扣合至扣合元件20之線圈易於鉤在鉤部31與桿部21之間之階差26。 Further, by making the lower surface of the hook portion 31 have a hard and smooth compression surface 32, even if the coil is stretched upward, the hook portion 31 itself is hard to be deformed upward. Further, since the rod portion 21 is thick and has high strength, it is possible to effectively prevent the rod portion 21 itself from being deformed so that the hook portion 31 faces upward. Further, in the forming surface fastener 1 of the first embodiment, the upper surface of the hook portion 31 is disposed to be higher than the upper surface of the rod portion 21 by the step 26. Thereby, the loop fastened to the fastening member 20 is liable to be hooked to the step 26 between the hook portion 31 and the stem portion 21.

其結果，於本實施例1之成形面扣結件1中，鉤在扣合元件20之鉤部31而扣合之線圈不易自該扣合元件20脫離。因此，根據本實施例1之成形面扣結件1，能夠穩定地獲得對母型面扣結件之較高之剝離強度。此處，剝離強度係指於將母型面扣結件貼合至成形面扣結件1而使兩者扣合之狀態下，將成形面扣結件1與母型面扣結件以相對地沿成形面扣結件1之高度方向拉離之方式拉伸時之扣合強度。 As a result, in the forming surface fastener 1 of the first embodiment, the stitch hooked to the hook portion 31 of the fastening member 20 is less likely to be detached from the fastening member 20. Therefore, according to the forming surface fastener 1 of the first embodiment, the high peeling strength to the female surface fastener can be stably obtained. Here, the peeling strength refers to a state in which the female surface fastener is attached to the forming surface fastening member 1 so that the two are fastened together. In the state, the fastening strength of the formed surface fastener 1 and the female surface fastener is stretched in a manner of being relatively pulled away in the height direction of the forming surface fastening member 1.

如上所述，本實施例1之成形面扣結件1具有先前未有之特徵性形態，藉此成為兼具桿部21不易折曲而獲得良好之肌膚觸感之優點、及對母型面扣結件具備較高之剝離強度或剪切強度之優點之新類型之成形面扣結件1。 As described above, the forming surface fastener 1 of the first embodiment has a characteristic form which has not been previously formed, thereby achieving the advantage that the rod portion 21 is not easily bent to obtain a good skin feel, and the mother side surface. A new type of forming surface fastener 1 having a high peel strength or shear strength advantage.

如此，剝離強度或剪切強度較高並且肌膚觸感較佳之本實施例1之成形面扣結件1尤其是較佳用於例如拋棄式尿布、乳幼兒之尿布套、保護手足之關節等之護體、腰用整姿內衣、手套等般之穿脫至身體之商品。進而，能夠藉由將如本實施例1之先前未有之新穎之成形面扣結件1追加提供至先前之成形面扣結件，而使成形面扣結件之變化增多。其結果，易於更確切地應對各種類型之母型面扣結件(不織布)。 Thus, the formed surface fastener 1 of the first embodiment having a high peel strength or shear strength and a good skin feel is particularly preferably used for, for example, a disposable diaper, a diaper cover for a baby, a joint for protecting hands and feet, and the like. The body, the waist, the underwear, the gloves, and the like are worn to the body. Further, it is possible to increase the variation of the forming surface fastener by additionally providing the previously formed molding surface fastener 1 as in the first embodiment to the previous molding surface fastener. As a result, it is easy to more accurately cope with various types of female-face fasteners (non-woven fabrics).

再者，上述實施例1之成形面扣結件1僅具有各扣合元件20之鉤部31朝左右方向(CD)中之一方向突出之扣合元件20而形成。然而，本發明之成形面扣結件亦可僅具有例如各扣合元件之鉤部朝左右方向中之另一方向突出之扣合元件而形成。又，本發明之成形面扣結件亦可為如圖12所示般鉤部31朝左右方向之一方向突出之扣合元件20、及鉤部31朝左右方向之另一方向突出之扣合元件20a混合存在而形成之成形面扣結件1a。該情形時，於本發明中，朝左右方向之一方向突出之扣合元件20與朝左右方向之另一方向突出之扣合元件20a之配置、各扣合元件20、20a之配設個數及比率等可任意選擇。 Further, the forming surface fastener 1 of the first embodiment described above is formed only by the fastening member 20 in which the hook portion 31 of each of the fastening members 20 protrudes in one of the left-right directions (CD). However, the forming surface fastener of the present invention may be formed only by a fastening member such as a hook portion of each of the fastening members protruding in the other of the left-right direction. Moreover, the forming surface fastening member of the present invention may be a fastening member 20 in which the hook portion 31 protrudes in one direction in the left-right direction as shown in FIG. 12, and a fastening portion in which the hook portion 31 protrudes in the other direction in the left-right direction. The element 20a is mixed to form a formed surface fastener 1a. In this case, in the present invention, the arrangement of the engaging elements 20 projecting in one of the right and left directions and the engaging elements 20a protruding in the other direction in the left-right direction, and the number of the engaging elements 20, 20a are arranged. And ratios can be arbitrarily chosen.

實施例2 Example 2

圖13係表示本實施例2之成形面扣結件之立體圖。圖14係僅表示成形面扣結件之扣合元件之立體圖。圖15~圖17分別係扣合元件之前視圖、右側側視圖、及左側側視圖。 Fig. 13 is a perspective view showing the forming surface fastener of the second embodiment. Figure 14 shows only forming A perspective view of the snap-fit component of the face fastener. 15 to 17 are front view, right side view, and left side view, respectively, of the snap-fit component.

於本實施例2之成形面扣結件2中，與上述實施例1之成形面扣結件1相比，扣合元件20b係使鉤部31b相對於桿部21之相對位置不同而形成。另一方面，基材部10之形狀、桿部21之形狀、及鉤部31b原本之形狀係與上述實施例1之基材部10之形狀、桿部21之形狀、及鉤部31之形狀相同。 In the molding surface fastener 2 of the second embodiment, the fastening member 20b is formed such that the relative position of the hook portion 31b with respect to the rod portion 21 is different from that of the molding surface fastener 1 of the first embodiment. On the other hand, the shape of the base portion 10, the shape of the rod portion 21, and the original shape of the hook portion 31b are the shape of the base portion 10 of the first embodiment, the shape of the rod portion 21, and the shape of the hook portion 31. the same.

因此，於本實施例2及下述實施例3中，主要對與上述實施例1之成形面扣結件1不同之部分或部位進行說明，針對與上述實施例1之成形面扣結件1具有實質上相同之形態或構成之部分或構件，使用相同符號而表示，藉此省略其說明。 Therefore, in the second embodiment and the following embodiment 3, a part or a portion different from the forming surface fastener 1 of the first embodiment will be mainly described, and the forming surface fastening member 1 of the above-described first embodiment will be described. Parts or members having substantially the same form or configuration are denoted by the same reference numerals, and the description thereof will be omitted.

本實施例2之成形面扣結件2具有薄板狀之基材部10、及立設於基材部10之上表面之複數個扣合元件20b。基材部10係與上述實施例1之基材部10同樣地形成。 The molding surface fastener 2 of the second embodiment has a thin plate-shaped base material portion 10 and a plurality of fastening elements 20b that are erected on the upper surface of the base material portion 10. The base material portion 10 is formed in the same manner as the base material portion 10 of the above-described first embodiment.

本實施例2之各扣合元件20b分別具有：桿部21，其自基材部10立起；及1個鉤部31b，其自桿部21之上端部沿交叉方向(CD)突出。於本實施例1之情形時，各扣合元件20b之鉤部31b均自桿部21朝交叉方向之相同朝向(右側)突出。 Each of the fastening elements 20b of the second embodiment has a rod portion 21 that rises from the base portion 10, and a hook portion 31b that protrudes from the upper end portion of the rod portion 21 in the intersecting direction (CD). In the case of the first embodiment, the hook portions 31b of the respective engaging elements 20b protrude from the rod portion 21 in the same direction (right side) in the intersecting direction.

本實施例2之桿部21係與上述實施例1之桿部21同樣地形成。 The rod portion 21 of the second embodiment is formed in the same manner as the rod portion 21 of the first embodiment.

本實施例2之鉤部31b本身係與上述實施例1之鉤部31同樣地形成。即，於本實施例2之鉤部31b中，朝向上方及左右側方之主外周面形成為球面狀，並且於該鉤部31b之下表面配置有藉由在成形步驟中受到按壓及壓縮而較主外周面光滑地形成之壓縮面32。又，本實施例2之鉤部31b具有於前後方向(桿部21之寬度方向)不對稱之形狀。 The hook portion 31b of the second embodiment is formed in the same manner as the hook portion 31 of the first embodiment described above. In other words, in the hook portion 31b of the second embodiment, the main outer peripheral surface facing the upper side and the left and right sides is formed in a spherical shape, and the lower surface of the hook portion 31b is disposed to be pressed and compressed in the forming step. A compression surface 32 that is formed smoother than the main outer peripheral surface. Further, the hook portion 31b of the second embodiment has a shape that is asymmetrical in the front-rear direction (the width direction of the rod portion 21).

另一方面，本實施例2中之鉤部31b相對於桿部21之相對位置係與上述實施例1之情形時不同。例如於上述實施例1之扣合元件20中，於鉤部31之上表面與桿部21之上表面之間設置有階差26。然而，於本實施例2之扣合元件20b中，鉤部31b之上表面之一部分係自桿部21之上表面連續地配置，於鉤部31b之上表面與桿部21之上表面之間，未設置有如上述實施例1般之階差26。 On the other hand, the relative position of the hook portion 31b in the second embodiment with respect to the rod portion 21 is different from that in the case of the above-described first embodiment. For example, in the fastening member 20 of the above-described first embodiment, a step 26 is provided between the upper surface of the hook portion 31 and the upper surface of the rod portion 21. However, in the fastening member 20b of the second embodiment, a part of the upper surface of the hook portion 31b is continuously disposed from the upper surface of the rod portion 21 between the upper surface of the hook portion 31b and the upper surface of the rod portion 21 The step 26 as in the above-described first embodiment is not provided.

該鉤部31b係以自桿部21朝C方向之一側(右側)突出之方式而形成。該情形時，即便鉤部31b之上表面與桿部21之上表面連續地配置，鉤部31b之與桿部21鄰接之上表面和桿部21之與鉤部31b鄰接之上表面係以互不相同之角度(朝向)而配置(換言之，鉤部31b之與桿部21鄰接之上表面和桿部21之與鉤部31b鄰接之上表面之切線方向互不相同)。 The hook portion 31b is formed to protrude from one side (right side) of the rod portion 21 in the C direction. In this case, even if the upper surface of the hook portion 31b is continuously disposed with the upper surface of the rod portion 21, the upper surface of the hook portion 31b adjacent to the rod portion 21 and the upper surface of the rod portion 21 adjacent to the hook portion 31b are mutually It is disposed at different angles (orientations) (in other words, the tangential direction of the upper surface of the hook portion 31b adjacent to the rod portion 21 and the upper surface of the rod portion 21 adjacent to the hook portion 31b are different from each other).

因此，於扣合元件20b之前視圖(圖15)中，存在於鉤部31b之上表面與桿部21之上表面之間配置凹陷般之邊界部之情況。再者，根據鉤部31b之突出方向，亦存在未形成如上所述般之邊界部，而使鉤部31b之上表面之一部分與桿部21之上表面光滑地連續地形成之情況。 Therefore, in the front view (FIG. 15) of the engaging member 20b, there is a case where a concave boundary portion is disposed between the upper surface of the hook portion 31b and the upper surface of the rod portion 21. Further, depending on the direction in which the hook portion 31b protrudes, there is a case where the boundary portion as described above is not formed, and one of the upper surfaces of the hook portion 31b and the upper surface of the rod portion 21 are smoothly formed continuously.

該情形時，鉤部31b之上表面(鉤部31b之上端緣)中之曲率半徑與上述實施例1之情形時同樣地，設定為0.01mm以上且0.5mm以下(較佳為0.05mm以上且0.1mm以下)。桿部21之上表面(前視或側視時之桿部21之上端緣)中之曲率半徑大於鉤部31b之上表面中之曲率半徑，並且設定為0.01mm以上且0.5mm以下(較佳為0.05mm以上且0.1mm以下)。 In this case, the radius of curvature in the upper surface of the hook portion 31b (the upper edge of the hook portion 31b) is set to be 0.01 mm or more and 0.5 mm or less (preferably 0.05 mm or more) as in the case of the first embodiment. 0.1mm or less). The radius of curvature in the upper surface of the rod portion 21 (the upper end edge of the rod portion 21 in the front view or the side view) is larger than the radius of curvature in the upper surface of the hook portion 31b, and is set to be 0.01 mm or more and 0.5 mm or less (preferably It is 0.05 mm or more and 0.1 mm or less).

具有如上所述之扣合元件20b之本實施例2之成形面扣結件2係與上述實施例1之情形時同樣地，使用如圖8所示般之製造裝置50而製造。於用於本實施例2之製造裝置50之模輪52中，為了使扣合元件20b成形而形成於模輪52之外周面部之成形用模腔具有與上述實施例1之情形時不同之形狀。 The molding surface fastener 2 of the second embodiment having the fastening element 20b as described above is manufactured using the manufacturing apparatus 50 as shown in Fig. 8 as in the case of the first embodiment. In the mold wheel 52 used in the manufacturing apparatus 50 of the second embodiment, in order to form the fastening member 20b, it is formed. The molding cavity for the outer peripheral surface of the die wheel 52 has a shape different from that of the case of the above-described first embodiment.

即，本實施例2之模輪52具有沿模輪52之旋轉軸方向重疊積層之複數個圓盤狀之金屬板55。雖然省略了圖示，但該模輪52之金屬板55具有：第1板，其形成有使扣合元件20b之鉤部31b成形之半球形狀之第1模腔及使桿部21之基端部22之一部分成形之輔助模腔；第2板55b，其形成有使扣合元件20b之桿部21成形之第2模腔57；及複數個第3板55c，其等作為間隔件而配置。 That is, the die wheel 52 of the second embodiment has a plurality of disk-shaped metal plates 55 which are laminated in the direction of the rotation axis of the die wheel 52. Although the illustration is omitted, the metal plate 55 of the die wheel 52 has a first plate formed with a hemispherical first cavity for shaping the hook portion 31b of the fastening member 20b and a base end of the stem portion 21. An auxiliary cavity formed by one of the portions 22; the second plate 55b is formed with a second cavity 57 for molding the stem portion 21 of the fastening element 20b; and a plurality of third plates 55c are disposed as spacers .

該情形時，本實施例2之第2板55b及第3板55c係與上述實施例1之第2板55b及第3板55c相同。另一方面，開口於第1板之第1積層面之第1模腔並未設置有扣合元件20b之鉤部31b之上表面與桿部21之上表面之間之階差。即，第1模腔之開口於第1積層面之徑向之最內側之位置係與第2板55b中之第2模腔57之開口於第2積層面之徑向之最內側之位置配合而形成。再者，本實施例2之模輪52除第1板之第1模腔之相對位置不同以外，係與上述實施例1之模輪52實質上同樣地形成。 In this case, the second plate 55b and the third plate 55c of the second embodiment are the same as the second plate 55b and the third plate 55c of the first embodiment. On the other hand, the first cavity opened in the first layer of the first plate is not provided with a step difference between the upper surface of the hook portion 31b of the engaging member 20b and the upper surface of the rod portion 21. In other words, the opening of the first cavity is located at the innermost side in the radial direction of the first layer, and the opening of the second cavity 57 in the second plate 55b is aligned with the innermost side of the radial direction of the second layer. And formed. Further, the die wheel 52 of the second embodiment is formed substantially in the same manner as the die wheel 52 of the first embodiment except that the relative positions of the first cavities of the first plate are different.

因此，於本實施例2之模輪52中，第1板之第1模腔亦於自模輪52之外周面朝內側相隔之位置形成為底切形狀。又，於本實施例2之第1板中，配置於第1模腔之模腔面與第1積層面之間之圓周狀之稜線部中之配置於徑向之外側之圓弧部分之稜線部係作為於自模輪52之模腔拔出扣合元件時局部地按壓壓縮鉤部之下表面之邊緣部而配置。 Therefore, in the die wheel 52 of the second embodiment, the first cavity of the first plate is also formed in an undercut shape at a position spaced apart from the outer circumferential surface of the die wheel 52. Further, in the first plate of the second embodiment, the ridge line of the circular arc portion disposed on the radially outer side of the circumferential ridge line portion between the cavity surface of the first cavity and the first buildup layer is disposed. The portion is disposed to partially press the edge portion of the lower surface of the compression hook portion when the fastening member is pulled out from the cavity of the mold wheel 52.

於本實施例2中，使用具有形成有如上所述之扣合元件20b之成形用模腔之模輪52之製造裝置50，與上述實施例1之情形時同樣地進行成形面扣結件2之製造。 In the second embodiment, the manufacturing apparatus 50 of the mold wheel 52 having the molding cavity for forming the fastening element 20b as described above is used, and the forming surface fastening member 2 is carried out in the same manner as in the case of the first embodiment. Manufacturing.

即，自擠出噴嘴53朝模輪52之外周面連續地擠出熔融之合成樹脂材料，於模輪52之外周面部使成形面扣結件(臨時成形面扣結件)成形。該成形面扣結件一面擔載於旋轉之模輪52之外周面部，一面冷卻至低於熔點之溫度。 In other words, the molten synthetic resin material is continuously extruded from the extrusion nozzle 53 toward the outer circumferential surface of the die wheel 52, and the molding surface fastener (temporary molding surface fastener) is formed on the outer peripheral surface of the die wheel 52. The forming surface fastener is carried on the outer peripheral surface of the rotating die wheel 52 while being cooled to a temperature lower than the melting point.

繼而，將於模輪52之外周面部成形之成形面扣結件藉由上述拾取輥54自模輪52之外周面部連續地並且強制地(強行)剝離。此時，於模輪52之模腔內成形之扣合元件(臨時扣合元件)之鉤部由第1板之上述邊緣部按壓壓縮並且摩擦。藉此，於鉤部之下表面形成光滑之壓縮面32。進而，此時，鉤部一面自邊緣部受到扭曲之外力一面由該邊緣部按壓，藉此，鉤部以自桿部朝鉤前端向上傾斜之方式朝上方傾斜或彎曲地整體變形，並且變形為於M方向上不對稱之形狀。 Then, the forming surface fastening member which is to be formed on the outer peripheral surface of the die wheel 52 is continuously and forcibly (forced) peeled off from the outer peripheral surface of the die wheel 52 by the above-described pickup roller 54. At this time, the hook portion of the engaging member (temporary fastening member) formed in the cavity of the die wheel 52 is pressed and compressed by the edge portion of the first plate and rubbed. Thereby, a smooth compression surface 32 is formed on the lower surface of the hook portion. Further, at this time, the hook portion is pressed by the edge portion while being twisted from the edge portion, whereby the hook portion is integrally deformed obliquely upward or curved upwardly from the rod portion toward the front end of the hook, and is deformed into Asymmetrical shape in the M direction.

然後，自模輪52剝離之成形面扣結件立即被導入至拾取輥54之相互以特定間隔相隔而配置之上側夾持輥54a與下側夾持輥54b之間，夾於該等上側夾持輥54a及下側夾持輥54b間。藉此，與上述實施例1之情形時同樣地，自桿部21朝上方變形之鉤部由上側夾持輥54a自上方按壓，故而能夠使朝其上方變形之鉤部以朝向左右方向(CD)之方式強制地(積極地)塑性變形。藉此，製造圖13所示之本實施例2之成形面扣結件2。 Then, the forming surface fastening members which are peeled off from the die wheel 52 are immediately introduced into the pickup roller 54 so as to be spaced apart from each other at a predetermined interval, and disposed between the upper side pinch roller 54a and the lower side pinch roller 54b, sandwiched between the upper side clamps Between the holding roller 54a and the lower nip roller 54b. As a result, in the same manner as in the case of the first embodiment, the hook portion that is deformed upward from the rod portion 21 is pressed from above by the upper nip roller 54a, so that the hook portion deformed upward can be oriented in the left-right direction (CD). The way of forced (positively) plastic deformation. Thereby, the forming surface fastener 2 of the second embodiment shown in Fig. 13 was produced.

其後，將通過拾取輥54之上側夾持輥54a及下側夾持輥54b間之於機械方向上長形之成形面扣結件2朝未圖示之切斷部搬送，利用該切斷部切斷成特定之長度而回收。或，以長形之成形面扣結件2之狀態卷狀地卷取至回收輥等而回收。 Then, the forming surface fastening member 2 which is elongated in the machine direction between the upper side nip roller 54a and the lower side nip roller 54b of the pickup roller 54 is conveyed to a cutting portion (not shown), and the cutting portion is used. The part is cut to a specific length and recovered. Alternatively, it is taken up in a roll shape in the form of a long-shaped forming surface fastening member 2, and collected in a recovery roll or the like.

於以如上方式製造之本實施例2之成形面扣結件2中，桿部21本身與鉤部31b本身分別具有與上述實施例1之桿部21及鉤部31相同之特徵性形態。即，扣合元件20b之桿部21係較粗並且以使桿部21之上表面(頂端面)呈球面之方式而形成。進而，於本實施例2中，於鉤部31b之上表面與桿部21之上表面之間並未設置有階差26，鉤部31b之上表面與桿部21之上表面係連續地配置。因此，於本實施例2之成形面扣結件2中，能夠獲得較上述實施例1之成形面扣結件2更良好之肌膚觸感。 In the molding surface fastener 2 of the second embodiment manufactured in the above manner, the rod portion 21 itself and the hook portion 31b have the same characteristic shape as the rod portion 21 and the hook portion 31 of the above-described first embodiment, respectively. state. That is, the stem portion 21 of the engaging member 20b is thick and formed such that the upper surface (tip surface) of the stem portion 21 is spherical. Further, in the second embodiment, the step 26 is not provided between the upper surface of the hook portion 31b and the upper surface of the rod portion 21, and the upper surface of the hook portion 31b and the upper surface of the rod portion 21 are continuously arranged. . Therefore, in the molded surface fastener 2 of the second embodiment, a better skin feel than the molded surface fastener 2 of the first embodiment can be obtained.

又，因扣合元件20b之桿部21之強度較高，故而能夠增大成形面扣結件2對母型面扣結件之剪切強度。進而，扣合元件20b之鉤部31b自桿部21之上端部朝左右方向(CD)突出，並且於鉤部31b之下表面局部地設置有光滑且較硬之壓縮面32。因此，於本實施例2之成形面扣結件2中，鉤在扣合元件20b之鉤部31b之線圈不易自扣合元件20b脫離，故而對母型面扣結件能夠獲得較高之剝離強度。 Moreover, since the strength of the rod portion 21 of the engaging element 20b is high, the shear strength of the forming surface fastener 2 to the female surface fastener can be increased. Further, the hook portion 31b of the engaging member 20b protrudes from the upper end portion of the rod portion 21 in the left-right direction (CD), and a smooth and hard compression surface 32 is partially provided on the lower surface of the hook portion 31b. Therefore, in the forming surface fastening member 2 of the second embodiment, the stitches of the hook portion 31b of the fastening member 20b are not easily detached from the fastening member 20b, so that the female profile fastening member can be highly peeled off. strength.

Figure 19 is a perspective view showing only the fastening elements of the forming surface fasteners. 20 to 22 are a front view, a right side view, and a left side view, respectively, of the fastening component.

本實施例3之成形面扣結件3具有薄板狀之基材部10、及立設於基材部10之上表面之複數個扣合元件70。基材部10係與上述實施例1及2之基材部10同樣地形成。 The molding surface fastener 3 of the third embodiment has a thin plate-shaped base material portion 10 and a plurality of fastening elements 70 that are erected on the upper surface of the base material portion 10. The base material portion 10 is formed in the same manner as the base material portion 10 of the above-described first and second embodiments.

本實施例3之各扣合元件70分別具有：桿部71，其自基材部10立起；及1個鉤部81，其自桿部71之上端部沿交叉方向(CD)突出。於本實施例3之情形時，各扣合元件70之鉤部81亦均自桿部71朝交叉方向之相同朝向突出。 Each of the fastening elements 70 of the third embodiment has a rod portion 71 that rises from the base portion 10, and a hook portion 81 that protrudes from the upper end portion of the rod portion 71 in the intersecting direction (CD). In the case of the third embodiment, the hook portions 81 of the respective engaging elements 70 also protrude from the rod portion 71 in the same direction in the intersecting direction.

扣合元件70之桿部71直立於基材部10之上表面。該桿部71具有：基端部72，其自基材部10豎起，並且於外周緣部整體具有彎曲面；桿本體部73，其於基端部72之上連續地配置；及桿頭部76，其配置於桿本體部73之上，具備如自上方壓塌般之形狀。本實施例3之桿部71具有以機械方向(MD)之中心位置為基準而於機械方向(桿部71之寬度方向)上對稱之形狀。 The rod portion 71 of the fastening member 70 is erected on the upper surface of the base portion 10. The rod portion 71 has: a base The end portion 72 is erected from the base portion 10 and has a curved surface as a whole at the outer peripheral portion; the rod body portion 73 is continuously disposed above the base end portion 72; and the rod head portion 76 is disposed on the rod portion The body portion 73 has a shape that collapses from above. The rod portion 71 of the third embodiment has a shape that is symmetrical in the machine direction (the width direction of the rod portion 71) with respect to the center position of the machine direction (MD).

為了提高桿部71對基材部10之強度，該桿部71之基端部72係以使與上下方向正交之剖面之面積隨著接近基材部10而遞增之方式而形成。 In order to increase the strength of the rod portion 71 to the base portion 10, the base end portion 72 of the rod portion 71 is formed such that the area of the cross section orthogonal to the vertical direction increases as it approaches the base portion 10.

桿本體部73之與上下方向正交之剖面呈接近半圓之形狀或較由圓之弧及弦包圍之半圓大之形狀。又，桿本體部73具有使與上下方向正交之剖面之面積隨著接近基材部10而遞增之形態。 The cross section of the rod main body portion 73 orthogonal to the vertical direction has a shape close to a semicircle or a shape larger than a semicircle surrounded by a circular arc and a chord. Further, the rod main body portion 73 has a shape in which the area of the cross section orthogonal to the vertical direction increases as it approaches the base material portion 10.

又，桿本體部73具有：平坦之鉤配設面74，其供配置鉤部81；及桿外周面，其於與上下方向正交之剖面中呈圓弧狀。鉤配設面74由與基材部10之上表面正交並且與CD正交之單一之平坦面形成。 Further, the lever main body portion 73 has a flat hook disposing surface 74 on which the hook portion 81 is disposed, and a rod outer peripheral surface which is arcuate in a cross section orthogonal to the vertical direction. The hook arrangement surface 74 is formed by a single flat surface orthogonal to the upper surface of the base material portion 10 and orthogonal to the CD.

又，桿部71具有於扣合元件70之前視時(參照圖20)配置於與鉤配設面74為相反側之桿背面75。該桿背面75係以如下方式而形成，即，於扣合元件70之前視時，使鉤配設面74與桿背面75之間之CD上之尺寸隨著遠離基材部10之上表面而遞減。 Further, the rod portion 71 is disposed on the rod back surface 75 on the side opposite to the hook arrangement surface 74 when the engaging element 70 is viewed from the front (see FIG. 20). The rod back surface 75 is formed in such a manner that, when viewed in the front view of the fastening member 70, the size of the CD between the hook arrangement surface 74 and the rod back surface 75 is made away from the upper surface of the base portion 10. Decrement.

該情形時，桿背面75於扣合元件70之前視時，具有：上端背面部75d，其配置於桿頭部76；上側曲面部75a，其凸狀(或圓弧狀)地配置於桿部71本體部之上端部；下側曲面部75b，其與基材部10鄰接而凹狀地配置於桿部71之下端部；及傾斜面部75c，其配置於上側曲面部75a及下側曲面部75b間。 In this case, the lever back surface 75 has an upper end back surface portion 75d disposed on the rod head portion 76 and an upper curved surface portion 75a which is convex (or arc-shaped) on the rod portion when viewed in front of the engaging member 70. 71. The upper end portion of the main body portion; the lower curved surface portion 75b is disposed adjacent to the base portion 10 and recessed in the lower end portion of the rod portion 71; and the inclined surface portion 75c is disposed on the upper curved surface portion 75a and the lower curved surface portion 75b.

進而，桿本體部73係以如下方式形成，即，於扣合元件70之側視時 (參照圖21或圖22)，使左右側緣間之M方向上之尺寸隨著遠離基材部10之上表面而遞減。 Further, the lever body portion 73 is formed in such a manner as to be viewed from the side of the fastening member 70. (Refer to FIG. 21 or FIG. 22), the dimension in the M direction between the left and right side edges is decreased as moving away from the upper surface of the base material portion 10.

藉由以如上方式形成本實施例3之桿本體部73，能夠使桿部71具有較高之強度，故而即便扣合元件70受到外力亦能夠不易變形。尤其是，能夠使桿部71不易以朝C方向之桿背面75側崩塌之方式變形。 By forming the rod main body portion 73 of the third embodiment as described above, the rod portion 71 can have a high strength, and therefore the engaging member 70 can be easily deformed even if it receives an external force. In particular, the rod portion 71 can be prevented from being deformed so as to collapse toward the rod back side 75 side in the C direction.

桿部71之桿頭部76以較小之高度尺寸較薄地形成於桿本體部73之上。該桿頭部76係以如下方式形成，即，與上下方向正交之剖面之形狀無論位於哪一高度位置，均具有大致相同之形狀。桿頭部76之上表面76a(換言之，桿部71之上表面或頂端面)形成為與基材部10之上表面平行之平坦面。又，桿頭部76之上表面76a係以與鉤部81之下述基端側上表面85a形成單一之平坦面之方式而配置。 The rod head portion 76 of the rod portion 71 is formed thinner on the rod body portion 73 with a smaller height. The rod head portion 76 is formed in such a manner that the shape of the cross section orthogonal to the vertical direction has substantially the same shape regardless of the height position. The upper surface 76a of the rod head 76 (in other words, the upper surface or the top end surface of the rod portion 71) is formed as a flat surface parallel to the upper surface of the base portion 10. Further, the upper surface 76a of the rod head portion 76 is disposed so as to form a single flat surface with the base end side upper surface 85a of the hook portion 81.

本實施例3之鉤部81具有如下特徵性形態，即，鉤前端部86朝下方傾斜，並且於鉤部81之下表面，配置有較鉤上表面85光滑地形成之壓縮面82。此處，鉤部81之下表面如上所述係指自鉤部81之前端跨及鉤部81中之與桿部71之連結部分之下端部而配置，並且朝下方或斜下方(即，朝基材部10)配置之鉤部81之外表面之部分。 The hook portion 81 of the third embodiment has a characteristic form in which the hook front end portion 86 is inclined downward, and a compression surface 82 which is formed smoother than the hook upper surface 85 is disposed on the lower surface of the hook portion 81. Here, the lower surface of the hook portion 81 is disposed from the front end of the hook portion 81 and the lower end portion of the joint portion of the hook portion 81 and the rod portion 71 as described above, and is directed downward or obliquely downward (ie, toward The base portion 10) is disposed on a portion of the outer surface of the hook portion 81.

又，本實施例3之鉤部81具有：鉤本體部83，其自桿部71朝左右方向(CD)突出；及前後一對加強肋部84，其等以自鉤本體部83之上端部朝前後方向(MD)伸出之方式而配置。鉤本體部83具有自桿部71隨著遠離而變小之前端較窄形狀。即，鉤本體部83係以使桿寬度方向上之尺寸(前後方向之尺寸)隨著遠離桿部71而遞減之方式而形成。藉由以此方式形成，能夠使線圈易於鉤在鉤本體部83。再者，鉤本體部83較佳為以使桿上下方向上之尺寸亦隨著遠離桿部71而遞減之方式而形成。又，藉由在鉤本體部 83之前後兩側配置加強肋部84，能夠有效地提高鉤部81之強度。 Further, the hook portion 81 of the third embodiment has a hook main body portion 83 which protrudes from the rod portion 71 in the left-right direction (CD), and a pair of front and rear reinforcing rib portions 84 which are equal to the upper end portion of the self-hook main body portion 83. It is arranged in such a manner that it extends in the front-rear direction (MD). The hook body portion 83 has a narrow shape from the stem portion 71 as it goes away from the front end. In other words, the hook main body portion 83 is formed such that the dimension in the width direction of the rod (the dimension in the front-rear direction) decreases as moving away from the rod portion 71. By being formed in this manner, the coil can be easily hooked to the hook body portion 83. Further, it is preferable that the hook main body portion 83 is formed such that the dimension in the vertical direction of the rod is also decreased as moving away from the rod portion 71. Again, by the hook body The reinforcing ribs 84 are disposed on both sides before and after 83, and the strength of the hook portion 81 can be effectively improved.

如圖20所示，該鉤部81之上表面(鉤上表面)85具有：基端側上表面85a，其配置於鉤基端部(桿連結側之端部)；及前端側上表面85b，其自基端側上表面85a朝鉤前端向下傾斜。鉤部81之基端側上表面85a自桿頭部76之上表面76a連續地配置，並且與該桿頭部76之上表面76a形成單一之平坦面。該情形時，鉤部81之平坦之基端側上表面85a跨及鉤本體部83及前後之加強肋部84而配置。 As shown in Fig. 20, the upper surface (hook upper surface) 85 of the hook portion 81 has a base end side upper surface 85a which is disposed at the hook base end (end portion of the rod coupling side); and a front end side upper surface 85b. It is inclined downward from the proximal end side upper surface 85a toward the front end of the hook. The proximal end side upper surface 85a of the hook portion 81 is continuously disposed from the upper surface 76a of the rod head 76, and forms a single flat surface with the upper surface 76a of the rod head portion 76. In this case, the flat base end side upper surface 85a of the hook portion 81 is disposed across the hook body portion 83 and the front and rear reinforcing rib portions 84.

於本實施例3之扣合元件70中，如上所述，桿頭部76之上表面76a與鉤部81之基端側上表面85a形成為與基材部10之上表面平行之平坦面。並且，鉤部81之前端側上表面85b朝鉤前端向下傾斜而形成。藉此，能夠使自上表面側觸摸成形面扣結件3時之扣合元件70之上端部之肌膚觸感變得良好。 In the fastening member 70 of the third embodiment, as described above, the upper surface 76a of the head portion 76 and the proximal end surface 85a of the hook portion 81 are formed as flat surfaces parallel to the upper surface of the base portion 10. Further, the front end side upper surface 85b of the hook portion 81 is formed to be inclined downward toward the front end of the hook. Thereby, it is possible to improve the skin feel of the upper end portion of the fastening element 70 when the upper surface side is in contact with the molding surface fastener 3.

鉤部81之下表面形成為如下形狀，即，例如於扣合元件70之前視時(參照圖20)，自鉤前端朝桿部71，以使與基材部10之間之間隔遞增之方式略微向上傾斜之後，以使與基材部10之間之間隔遞減之方式向下傾斜。即，於本實施例3之鉤部81中，藉由使鉤前端部86朝下方傾斜而形成，使鉤部81之下表面於扣合元件70之前視時具備較小地彎曲或彎折成如使線圈鉤在鉤前端與桿部71間般之凹狀之曲面(凹面)而形成。 The lower surface of the hook portion 81 is formed in a shape such as, for example, before the fastening member 70 (see FIG. 20), from the front end of the hook toward the rod portion 71 so as to increase the interval from the base portion 10 After slightly tilting upward, it is inclined downward so as to be spaced apart from the base portion 10. That is, in the hook portion 81 of the third embodiment, the hook front end portion 86 is formed to be inclined downward, so that the lower surface of the hook portion 81 is slightly bent or bent in the front view of the fastening member 70. The coil is formed by hooking a concave curved surface (concave surface) between the front end of the hook and the rod portion 71.

又，鉤部81之凹面狀地形成之下表面具有藉由受到按壓及壓縮而較鉤部81之上表面光滑且光潤地形成之壓縮面82。該壓縮面82較鉤部81之上表面更多地反射光，亦存在於壓縮面82局部地觀察到光澤之情況。又，鉤部81之壓縮面82較佳為較鉤部81之上表面硬地形成。 Further, the lower surface of the hook portion 81 is formed in a concave shape to have a compression surface 82 which is formed to be smoother and smoother than the upper surface of the hook portion 81 by being pressed and compressed. The compression surface 82 reflects more light than the upper surface of the hook portion 81, and there is also a case where the compression surface 82 partially observes gloss. Further, the compression surface 82 of the hook portion 81 is preferably formed harder than the upper surface of the hook portion 81.

進而，於本實施例3中，當自機械方向觀察鉤部81時(尤其是自後方側觀察鉤部81時)，鉤部81之前端部86之外表面中之曲率半徑係與上述實施例1之情形時同樣地，設定為0.06mm以上且0.18mm以下之範圍內，較佳設定為0.12mm以上且0.15mm以下之範圍內。 Further, in the third embodiment, when the hook portion 81 is viewed from the mechanical direction (especially from the rear) When the hook portion 81 is viewed from the side, the radius of curvature of the outer surface of the front end portion 86 of the hook portion 81 is set to be in the range of 0.06 mm or more and 0.18 mm or less, preferably in the same manner as in the case of the first embodiment. It is in the range of 0.12 mm or more and 0.15 mm or less.

於本實施例3之扣合元件70中，雖然桿部71具有於M方向(桿部71之寬度方向)上對稱之形狀，但鉤部81具有於M方向(鉤部81之寬度方向)上不對稱之形狀。即，鉤部81形成為以M方向之中心位置為基準而配置於前方之前半部與配置於後方之後半部相互不對稱之完全不同之形態。又，於自C方向之鉤部81側觀察扣合元件70之側視(參照圖21)時，係以夾於鉤部81之前端側上表面85b與壓縮面82之方式配置前端面87。 In the fastening member 70 of the third embodiment, the rod portion 71 has a shape symmetrical in the M direction (the width direction of the rod portion 71), but the hook portion 81 has the M direction (the width direction of the hook portion 81). Asymmetrical shape. In other words, the hook portion 81 is formed in a completely different form in which the front half portion is disposed asymmetrically with respect to the rear rear half portion with respect to the center position in the M direction. When the side view of the fastening member 70 is viewed from the side of the hook portion 81 in the C direction (see FIG. 21), the distal end surface 87 is disposed so as to be sandwiched between the upper end surface 85b and the compression surface 82 of the hook portion 81.

該情形時，鉤前端部86配置於較鉤部81之前後方向(MD)之中心位置更靠後方。又，鉤部81中之壓縮面82之後端部以例如於圖20所示之扣合元件70之前視時隱藏而看不見之方式，配置於較該壓縮面82之前端部高之位置。 In this case, the hook front end portion 86 is disposed further rearward than the center position of the rear direction (MD) of the hook portion 81. Further, the rear end portion of the compression surface 82 in the hook portion 81 is disposed at a position higher than the end portion of the compression surface 82 so that the fastening member 70 shown in FIG. 20 is hidden from view before, for example, invisible.

又，於本實施例3中，扣合元件70之具體大小係以如下方式設定。 Further, in the third embodiment, the specific size of the fastening member 70 is set as follows.

例如針對上下方向，扣合元件70中之距基材部10之上表面之最大高度尺寸H1設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。鉤部81之前端部86中之距基材部10之上表面之上下方向之高度尺寸H4小於上述最大高度尺寸H1，並且設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。 For example, in the vertical direction, the maximum height H1 from the upper surface of the base member 10 in the fastening member 70 is set to be 0.1 mm or more and 1.5 mm or less, and preferably 0.2 mm or more and 1.0 mm or less. The height dimension H4 of the front end portion 86 of the hook portion 81 from the upper surface of the upper surface of the base material portion 10 is smaller than the maximum height dimension H1, and is set to be 0.1 mm or more and 1.5 mm or less, preferably 0.2 mm or more. 1.0mm or less.

針對M方向(扣合元件20之寬度方向)，桿部71中之機械方向之最大尺寸(即，桿部71之基端部72中之機械方向之尺寸)L1設定為0.1mm以上且1.5mm以下，較佳設定為0.2mm以上且1.0mm以下。又，鉤部81中之機械方向之最大尺寸L2設定為0.01mm以上且1.0mm以下，較佳設定為0.05 mm以上且0.5mm以下。 For the M direction (the width direction of the snap member 20), the maximum dimension of the mechanical direction in the stem portion 71 (i.e., the dimension of the mechanical direction in the base end portion 72 of the stem portion 71) L1 is set to be 0.1 mm or more and 1.5 mm. Hereinafter, it is preferably set to 0.2 mm or more and 1.0 mm or less. Further, the maximum dimension L2 of the mechanical direction in the hook portion 81 is set to be 0.01 mm or more and 1.0 mm or less, preferably 0.05. Above mm and below 0.5 mm.

針對C方向，桿部71中之交叉方向之最大尺寸(即，桿部71之基端部72中之交叉方向之尺寸)W1設定為0.1mm以上且1.5mm以下，較佳設定為0.1mm以上且1.0mm以下。又，鉤部81之交叉方向之最大尺寸(即，自鉤部81之前端至桿部71之鉤配設面74之交叉方向之尺寸)W2設定為0.01mm以上且1.0mm以下，較佳設定為0.05mm以上且0.5mm以下。 In the C direction, the maximum dimension in the intersecting direction of the rod portion 71 (that is, the dimension in the intersecting direction of the base end portion 72 of the rod portion 71) W1 is set to be 0.1 mm or more and 1.5 mm or less, preferably set to 0.1 mm or more. And less than 1.0mm.

如上所述之本實施例3之成形面扣結件3係使用圖23所示之製造裝置90而製造。 The forming surface fastener 3 of the present embodiment 3 as described above is manufactured using the manufacturing apparatus 90 shown in Fig. 23 .

該製造裝置90具有：成形裝置51，其進行成形面扣結件3之下述一次成形體之成形；拾取輥54，其將所成形之一次成形體自成形裝置51剝離，並且使一次成形體之下述臨時元件之一部分變形；及加熱按壓裝置91，其對自拾取輥54送出之一次成形體加熱並按壓。 The manufacturing apparatus 90 has a molding apparatus 51 that performs molding of a primary molded body of the forming surface fastener 3, and a pickup roller 54 that peels the formed primary molded body from the forming apparatus 51 and causes the primary molded body to be formed. One of the following temporary members is partially deformed; and a heating pressing device 91 that heats and presses the primary molded body sent from the pickup roller 54.

該情形時，於本實施例3之成形裝置51及拾取輥54，係使用與上述實施例1相同之成形裝置51及拾取輥54。因此，於本實施例3之模輪52中，第1板55a之第1模腔56於自模輪52之外周面朝內側相隔之位置形成為使成形面扣結件3之下述一次成形體無法以原本之形狀脫模之底切形狀。進而，設置於第1板55a之圓周狀之稜線部中之配置於徑向之外側之圓弧部分之稜線部係作為於將一次成形體之臨時元件拔出時局部地按壓壓縮臨時元件之一次鉤部之下表面之邊緣部60配置。 In this case, in the molding apparatus 51 and the pickup roller 54 of the third embodiment, the molding apparatus 51 and the pickup roller 54 which are the same as those of the above-described first embodiment are used. Therefore, in the die wheel 52 of the third embodiment, the first cavity 56 of the first plate 55a is formed at a position spaced apart from the outer peripheral surface of the die wheel 52 so that the forming surface fastener 3 can be formed at one time. The undercut shape that the body cannot be demolded in its original shape. Enter Further, the ridge line portion of the circular arc portion disposed on the radially outer side of the circumferential ridge line portion of the first plate 55a serves as a partial pressing of the temporary member when the temporary member of the primary molded body is pulled out. The edge portion 60 of the lower surface of the hook portion is disposed.

本實施例3之加熱按壓裝置91具有上下一對按壓輥(砑光輥)91a、91b。上側按壓輥91a與下側按壓輥91b隔開特定之間隔相對向配置。該情形時，上側按壓輥91a及下側按壓輥91b間之間隔可藉由未圖示之高度調整機構而調整。於本實施例3之情形時，係對應於自所製造之成形面扣結件3之基材部10之下表面(背面)至桿頭部76之上表面76a之高度尺寸而調整。 The heating and pressing device 91 of the third embodiment has a pair of upper and lower pressing rolls (calender rolls) 91a and 91b. The upper pressing roller 91a and the lower pressing roller 91b are disposed to face each other with a predetermined interval therebetween. In this case, the interval between the upper pressing roller 91a and the lower pressing roller 91b can be adjusted by a height adjusting mechanism (not shown). In the case of the third embodiment, it is adjusted corresponding to the height dimension from the lower surface (back surface) of the base portion 10 of the formed surface fastener 3 to the upper surface 76a of the head portion 76.

上側按壓輥91a於內部具備未圖示之加熱源。該情形時，上側按壓輥91a之表面溫度設定為能夠使形成成形面扣結件3之合成樹脂軟化之溫度。具體而言，係以變成「該合成樹脂之熔點-40℃之溫度」以上且「該熔點-10℃之溫度」以下之特定之溫度之方式而設定。又，上側按壓輥91a係以於圖23中朝逆時針方向旋轉之方式而配置。上側按壓輥91a之外周面成為自上方按壓利用一次成形步驟成形之一次成形體之經加熱之臨時元件。 The upper pressing roller 91a is provided with a heating source (not shown) inside. In this case, the surface temperature of the upper pressing roller 91a is set to a temperature at which the synthetic resin forming the forming surface fastener 3 is softened. Specifically, it is set so as to become a specific temperature equal to or higher than the "temperature of the synthetic resin at -40 ° C" and "the temperature of the melting point of -10 ° C". Further, the upper pressing roller 91a is disposed to rotate in the counterclockwise direction in FIG. The outer peripheral surface of the upper pressing roller 91a is a heated temporary member that presses the primary molded body formed by the primary forming step from above.

下側按壓輥91b係以於圖23中順時針地旋轉之方式而配置，成為自下支持所搬送之一次成形體之支持面。再者，於本發明中，亦可利用未圖示之上側皮帶機構及/或下側皮帶機構來代替上側按壓輥91a及/或下側按壓輥91b。該情形時，上側皮帶機構及下側皮帶機構分別具有環形皮帶、及捲繞有該環形皮帶並且使環形皮帶朝一方向旋轉之左右一對旋轉輥。 The lower pressing roller 91b is disposed so as to rotate clockwise in FIG. 23, and serves as a supporting surface for the primary molded body to be conveyed from the lower support. Further, in the present invention, the upper side belt mechanism and/or the lower side belt mechanism (not shown) may be used instead of the upper side pressing roller 91a and/or the lower side pressing roller 91b. In this case, the upper belt mechanism and the lower belt mechanism respectively have an endless belt, and a pair of left and right rotating rollers around which the endless belt is wound and the endless belt is rotated in one direction.

於使用具有如上所述之成形裝置51、拾取輥54、及加熱按壓裝置91之製造裝置90製造本實施例3之成形面扣結件3之情形時，首先，進行藉由成形裝置51使成形面扣結件3之一次成形體成形之一次成形步驟。本實施例3之一次成形步驟係與上述實施例1之成形步驟同樣地進行。 When the molding surface fastener 3 of the third embodiment is manufactured by using the molding apparatus 90 having the molding apparatus 51, the pickup roller 54, and the heating pressing apparatus 91 as described above, first, shaping is performed by the molding apparatus 51. One forming step of forming the primary forming body of the surface fastener 3 . Real The primary forming step of the third embodiment was carried out in the same manner as the forming step of the above-described first embodiment.

即，於本實施例3之一次成形步驟中，自擠出噴嘴53朝模輪52之外周面連續地擠出熔融之合成樹脂材料，藉此對連續擠出噴嘴53與旋轉之模輪52之間之空間部、及設置於模輪52之外周面部之各模腔(空間部)內填充合成樹脂材料。 That is, in the primary forming step of the third embodiment, the molten synthetic resin material is continuously extruded from the extrusion nozzle 53 toward the outer peripheral surface of the die wheel 52, whereby the continuous extrusion nozzle 53 and the rotating die wheel 52 are The space portion between the space and the cavity (space portion) provided on the outer peripheral surface of the die wheel 52 are filled with a synthetic resin material.

進而，一面將所填充之合成樹脂材料擔載於模輪52之外周面，一面使其冷卻至低於熔點之溫度，藉此成形具有未圖示之一次鉤部及一次桿部之複數個臨時元件立設於基材部10之上表面而成之一次成形體(臨時一次成形體)。此時所成形之一次成形體(臨時一次成形體)係與上述實施例1之臨時成形面扣結件相同。 Further, while the filled synthetic resin material is carried on the outer peripheral surface of the die wheel 52 and cooled to a temperature lower than the melting point, a plurality of temporary portions having a primary hook portion and a primary rod portion (not shown) are formed. A primary molded body (temporary primary molded body) in which the element is erected on the upper surface of the base material portion 10. The primary molded body (temporary primary molded body) formed at this time is the same as the temporary molded surface fastener of the above-described first embodiment.

其後，將於模輪52成形之一次成形體藉由上述拾取輥54自模輪52之外周面部連續地並且強制地(強行)剝離。此時，於形成於模輪52之外周面部之模腔中，第1板55a之第1模腔56如上所述形成為底切形狀。 Thereafter, the primary molded body formed by the die wheel 52 is continuously and forcibly (forced) peeled off from the outer peripheral surface of the die wheel 52 by the above-described pickup roller 54. At this time, in the cavity formed in the outer peripheral surface of the die wheel 52, the first cavity 56 of the first plate 55a is formed into an undercut shape as described above.

因此，藉由利用拾取輥54拉伸一次成形體，於模腔內成形之臨時元件之半球形狀之一次鉤部藉由形成於第1板55a之上述邊緣部60，自一次鉤部之下表面側按壓壓縮。此時，因模輪52沿機械方向旋轉，故而一次鉤部亦受到藉由第1板55a之邊緣部60朝機械方向扭曲般之外力。藉此，於一次鉤部之下表面，與上述實施例1之情形時同樣地，形成光滑且較硬之壓縮面82。 Therefore, by stretching the formed body once by the pickup roller 54, the primary hook portion of the hemispherical shape of the temporary member formed in the cavity is formed on the edge portion 60 of the first plate 55a from the lower surface of the first hook portion. Side compression. At this time, since the die wheel 52 rotates in the machine direction, the primary hook portion is also subjected to a force that is twisted in the machine direction by the edge portion 60 of the first plate 55a. Thereby, a smooth and hard compression surface 82 is formed on the lower surface of the primary hook portion as in the case of the above-described first embodiment.

進而，於將一次鉤部自第1模腔56拔出時，一次鉤部一面自第1板55a之邊緣部60受到外力，一面由該邊緣部60按壓，藉此一次鉤部以自一次桿部朝鉤前端向上傾斜之方式朝上方傾斜或彎曲地整體變形，並且變形為於M方向上不對稱之形狀。 Further, when the primary hook portion is pulled out from the first cavity 56, the primary hook portion receives an external force from the edge portion 60 of the first plate 55a, and is pressed by the edge portion 60, whereby the primary hook portion is self-priming. The portion is integrally deformed obliquely or curved toward the upper side toward the upper end of the hook, and is deformed into an asymmetrical shape in the M direction.

自模輪52剝離之一次成形體立即被導入並夾於拾取輥54之上側夾持輥54a與下側夾持輥54b之間。此時，藉由上側夾持輥54a自上方按壓朝臨時元件之上方變形之一次鉤部。藉此，能夠使以向上傾斜之方式而變形之一次鉤部以朝向C方向之方式強制地(積極地)朝下方塑性變形。藉此，製作本實施例3之一次成形體。此時製作之本實施例3之一次成形體具有與圖1所示之上述實施例1之成形面扣結件1相同之構成(構造)。 The primary molded body peeled off from the die wheel 52 is immediately introduced and sandwiched between the upper side pinch roller 54a and the lower side pinch roller 54b of the pickup roller 54. At this time, the upper hook roller 54a presses the primary hook portion which is deformed toward the upper side of the temporary member from above. Thereby, the primary hook portion which is deformed in an upwardly inclined manner can be forcibly (positively) plastically deformed downward toward the C direction. Thus, the primary molded body of the third embodiment was produced. The primary molded body of the third embodiment produced at this time has the same configuration (structure) as that of the molded surface fastener 1 of the first embodiment shown in Fig. 1 .

即，本實施例3之一次成形體具有基材部10及立設於基材部10之複數個臨時元件(實施例1之扣合元件20)。又，臨時元件具有：一次桿部(實施例1之桿部21)，其自基材部10立起；及一次鉤部(實施例1之鉤部31)，其自該一次桿部之上端部朝C方向突出。進而，於臨時元件之一次桿部與一次鉤部之間，形成有使一次鉤部之上表面高於一次桿部之上表面之階差。 That is, the primary molded body of the third embodiment has the base portion 10 and a plurality of temporary members (the fastening members 20 of the first embodiment) that are erected on the base portion 10. Further, the temporary member has a primary rod portion (the rod portion 21 of the first embodiment) which rises from the base portion 10, and a primary hook portion (the hook portion 31 of the first embodiment) which is from the upper end of the primary rod portion. The department stands in the direction of C. Further, between the primary rod portion of the temporary element and the primary hook portion, a step in which the upper surface of the primary hook portion is higher than the upper surface of the primary rod portion is formed.

繼而，將通過拾取輥54而獲得之上述一次成形體(實施例1之成形面扣結件1)朝進行二次成形步驟之加熱按壓裝置91搬送，導入至加熱按壓裝置91之上側按壓輥91a與下側按壓輥91b之間。進而，藉由使一次成形體通過上側按壓輥91a及下側按壓輥91b間，臨時元件中之一次桿部之上端部及一次鉤部之上端部(即，實施例1之扣合元件70中之桿部71之上端部及鉤部81之上端部)由上側按壓輥91a加熱而軟化，並且自上方按壓而被壓扁。 Then, the primary molded body (the molded surface fastener 1 of the first embodiment) obtained by the pickup roller 54 is conveyed toward the heating press device 91 that performs the secondary molding step, and is introduced to the upper pressing roller 91a of the heating pressing device 91. Between the lower pressing roller 91b and the lower side. Further, by passing the primary molded body between the upper pressing roller 91a and the lower pressing roller 91b, the upper end portion of the primary rod portion and the upper end portion of the primary hook portion in the temporary member (that is, the fastening member 70 of the first embodiment) The upper end portion of the rod portion 71 and the upper end portion of the hook portion 81 are heated by the upper pressing roller 91a to be softened, and pressed from above to be crushed.

藉由進行此種二次成形步驟，能夠使鉤部81之前端較進行二次成形步驟之前更朝下方彎折。又，一次成形體之一次桿部之上端部與一次鉤部之上端部以一面擴展一面平坦化之方式而熱變形，桿頭部76之上表面76a與鉤部81之基端側上表面85a形成為單一之平坦面。進而，形成鉤部81之一對加強肋部84。 By performing such a secondary forming step, the front end of the hook portion 81 can be bent downward more than before the secondary forming step. Further, the upper end portion of the primary rod portion of the primary molded body and the upper end portion of the primary hook portion are thermally deformed so as to be flattened on one side, and the upper surface 75a of the rod head portion 76 and the base end side upper surface 85a of the hook portion 81 are formed. Formed as a single flat surface. Further, one of the hook portions 81 is formed to the reinforcing rib portion 84.

藉此，成形圖18~圖22所示般之本實施例3之扣合元件70，故而製造圖18所示之本實施例3之成形面扣結件3。其後，將通過加熱按壓裝置91之於機械方向上長形之成形面扣結件3朝未圖示之切斷部搬送，利用該切斷部切斷成特定之長度而回收。或，以長形之成形面扣結件3之狀態卷狀地卷取至回收輥等而回收。 Thereby, the engaging member 70 of the third embodiment shown in Figs. 18 to 22 is formed, and the forming surface fastener 3 of the third embodiment shown in Fig. 18 is produced. Then, the forming surface fastener 3 which is elongated in the machine direction by the heating and pressing device 91 is conveyed to a cutting portion (not shown), and is cut into a specific length by the cutting portion and collected. Alternatively, it may be wound up in a roll shape in the form of a long-form forming surface fastener 3 to a recovery roll or the like.

以如上方式製造之本實施例3之成形面扣結件3具有：桿部71，其自基材部10較粗地立設；及微小之鉤部81，其自桿部71之上端部朝CD突出。進而，扣合元件70之鉤部81之鉤前端部86朝下方傾斜而形成，並且當自C方向觀察扣合元件70之鉤部81時(參照圖21)，鉤部81於鉤部81之寬度方向(M方向)不對稱地形成。設置有此種鉤部81之本實施例3之扣合元件70具有與先前之J字狀、棕櫚樹狀、及蘑菇狀完全不同之特徵性形態，藉此，具有先前所無法獲得之如下特徵性性質。 The forming surface fastening member 3 of the third embodiment manufactured in the above manner has a rod portion 71 which is erected from the base portion 10 and a minute hook portion 81 which faces from the upper end portion of the rod portion 71 toward The CD stands out. Further, the hook front end portion 86 of the hook portion 81 of the engaging member 70 is formed to be inclined downward, and when the hook portion 81 of the fastening member 70 is viewed from the C direction (refer to FIG. 21), the hook portion 81 is at the hook portion 81. The width direction (M direction) is formed asymmetrically. The fastening member 70 of the third embodiment provided with such a hook portion 81 has a characteristic form completely different from the previous J-shape, palm tree shape, and mushroom shape, thereby having the following features which were not previously obtained. Sexual nature.

若具體進行說明，則於本實施例3之成形面扣結件3中，扣合元件70之桿部71係較粗地形成，故而能夠提高桿部71之強度。因此，本實施例3之成形面扣結件3與上述實施例1之情形時同樣地，能夠易於將母型面扣結件之線圈鉤在成形面扣結件3之扣合元件70從而穩定地扣合。進而，藉由使桿部71之強度較高，能夠增大成形面扣結件3對母型面扣結件之剪切強度。 Specifically, in the molded surface fastener 3 of the third embodiment, the stem portion 71 of the engaging member 70 is formed thick, so that the strength of the stem portion 71 can be improved. Therefore, in the same manner as in the case of the first embodiment, the molding surface fastener 3 of the third embodiment can easily hook the stitch of the female surface fastener member to the fastening member 70 of the forming surface fastening member 3 to stabilize Fasten the ground. Further, by making the strength of the rod portion 71 high, the shear strength of the forming surface fastener 3 to the female surface fastener can be increased.

又，於本實施例3之扣合元件70中，極小之鉤部81自桿部71之上端部朝左右方向(CD)突出，並且鉤前端部86朝下方傾斜而配置。進而，扣合元件70之鉤部81之下表面如上所述局部地具有較鉤部81之上表面光滑地形成之壓縮面82。又，鉤本體部83具有隨著遠離桿部71而變得前端較窄之形狀。 Further, in the engaging element 70 of the third embodiment, the extremely small hook portion 81 protrudes from the upper end portion of the rod portion 71 in the left-right direction (CD), and the hook front end portion 86 is inclined downward. Further, the lower surface of the hook portion 81 of the fastening member 70 partially has a compression surface 82 which is formed smoother than the upper surface of the hook portion 81 as described above. Further, the hook main body portion 83 has a shape in which the front end becomes narrower as it goes away from the rod portion 71.

因此，於本實施例3之成形面扣結件3中，易於使線圈扣合元件70之鉤部81，又，該經鉤住之線圈不易自扣合元件70脫離，故而對母型面扣結件能夠穩定地獲得較高之剝離強度。 Therefore, in the forming surface fastening member 3 of the third embodiment, the hook portion 81 of the coil fastening member 70 is easily detached, and the hooked coil is not easily detached from the fastening member 70, so that the female surface fastener is removed. The knot can stably obtain a high peel strength.

進而，於本實施例3之扣合元件70中，桿部71中之桿頭部76之上表面76a與鉤部81之基端側上表面85a形成為與基材部10之上表面平行之連續之平坦面。又，如此平坦之桿頭部76之上表面76a與鉤部81之基端側上表面85a以較大之面積露出於成形面扣結件3之上方。藉此，能夠穩定地獲得自上表面側觸摸成形面扣結件3時之良好之肌膚觸感或良好之觸感。 Further, in the fastening member 70 of the third embodiment, the upper surface 76a of the stem portion 76 and the proximal end surface 85a of the hook portion 81 in the stem portion 71 are formed to be parallel to the upper surface of the base portion 10. Continuous flat surface. Further, the upper surface 76a of the flat head portion 76 and the base end side upper surface 85a of the hook portion 81 are exposed above the forming surface fastening member 3 with a large area. Thereby, it is possible to stably obtain a good skin feel or a good touch when the upper surface side touches the molded surface fastener 3 is obtained.

具有如上所述之特徵性性質之本實施例3之成形面扣結件3尤其是較佳用於例如拋棄式尿布、乳幼兒之尿布套、保護手足之關節等之護體、腰用整姿內衣、手套等般之穿脫至身體之商品。進而，能夠藉由將如本實施例3之先前未有之新穎之成形面扣結件3追加提供至先前之成形面扣結件，而使成形面扣結件之變化增多。其結果，易於更確切地應對各種類型之母型面扣結件(不織布)。 The forming surface fastener 3 of the present embodiment 3 having the characteristic properties as described above is particularly preferably used for, for example, a disposable diaper, a diaper cover for a baby, a joint for protecting the joints of the hands and feet, and a waist-like posture. Underwear, gloves, and the like are worn to the body. Further, it is possible to increase the variation of the forming surface fastening member by additionally providing the previously formed molding surface fastener 3 as in the third embodiment to the previous molding surface fastening member. As a result, it is easy to more accurately cope with various types of female-face fasteners (non-woven fabrics).

再者，本實施例3之成形面扣結件3於成形面扣結件3之製造步驟中，係使用成形裝置51及拾取輥54，製作具有與圖1所示之上述實施例1之成形面扣結件1(參照圖1)相同之構成(構造)之一次成形體，其後，藉由將該所獲得之一次成形體導入至加熱按壓裝置91之上側按壓輥91a與下側按壓輥91b之間而製造。 Further, in the manufacturing step of the forming surface fastening member 3 of the third embodiment, the forming device 51 and the pickup roller 54 are used to form the molding having the above-described embodiment 1 shown in FIG. The primary molded body having the same configuration (structure) as the surface fastener 1 (see FIG. 1), and thereafter, the obtained primary molded body is introduced to the upper pressing roller 91a and the lower pressing roller of the heating pressing device 91. Manufactured between 91b.

然而，於本實施例3中，通過拾取輥54之上側夾持輥54a及下側夾持輥54b間之一次成形體亦可不為上述實施例1之成形面扣結件1，而係具有與上述實施例2之成形面扣結件2(參照圖13)相同之構成(構造)者。 However, in the third embodiment, the primary molded body between the upper side nip roller 54a and the lower side nip roller 54b of the pickup roller 54 may not be the formed surface fastener 1 of the above-described first embodiment, but has The configuration (structure) of the molded surface fastener 2 (see Fig. 13) of the second embodiment described above is the same.

藉由將此種一次成形體(即，實施例2之成形面扣結件2)導入至加熱按壓裝置91而進行上述二次成形步驟，亦能夠製造具有與本實施例3中所說明之扣合元件70大致相同之構成(構造)之複數個扣合元件立設於基材部10而成之成形面扣結件。以此方式製造之成形面扣結件成為實施例3之變化例之成形面扣結件，能夠獲得與圖18~圖22所示之實施例3之成形面扣結件3相同之效果。 By introducing such a primary molded body (i.e., the forming surface fastening member 2 of Embodiment 2) into a heating press The pressing device 91 performs the above-described secondary forming step, and a plurality of fastening members having substantially the same configuration (structure) as the fastening member 70 described in the third embodiment can be manufactured and erected on the base portion 10 The forming surface is fastened. The molding surface fastener member manufactured in this manner is a molding surface fastener member according to a modification of the third embodiment, and the same effect as that of the molding surface fastener member 3 of the third embodiment shown in Figs. 18 to 22 can be obtained.

再者，於上述實施例1~實施例3中，對成形面扣結件之各扣合元件具有1個桿部及自該桿部朝交叉方向(CD)突出之1個鉤部之情形時進行了說明。然而，於本發明中，亦可對扣合元件之1個桿部突出配置複數個鉤部。 Further, in the above-described first to third embodiments, each of the engaging elements of the forming surface fastener has one rod portion and one hook portion protruding from the rod portion in the intersecting direction (CD). It was explained. However, in the present invention, a plurality of hook portions may be protruded from one of the rod portions of the fastening member.

此處，一面參照圖式，一面對例如實施例1之變化例進行具體說明。圖24係表示實施例1之變化例之扣合元件20c。該圖24之扣合元件20c具有：桿部21c，其自基材部10立起；及2個鉤部31，其等自桿部21c之上端部朝交叉方向之相同朝向而突出。 Here, a modification of the first embodiment will be specifically described with reference to the drawings. Fig. 24 is a view showing a fastening member 20c according to a modification of the first embodiment. The engaging element 20c of Fig. 24 has a rod portion 21c that rises from the base portion 10, and two hook portions 31 that protrude from the upper end portion of the rod portion 21c in the same direction in the intersecting direction.

該變化例之桿部21c具有與上述實施例1之桿部21相同之形狀，但較上述實施例1之桿部21大地形成。即，變化例之桿部21c與上述實施例1之桿部21具有相似之關係。又，變化例之2個鉤部31分別以與上述實施例1之鉤部31相同之形狀及相同之大小而形成。 The rod portion 21c of this modification has the same shape as the rod portion 21 of the above-described first embodiment, but is formed larger than the rod portion 21 of the first embodiment. That is, the rod portion 21c of the modified example has a similar relationship with the rod portion 21 of the above-described first embodiment.
