FIG. 7 is a schematic diagram showing a line to be cut for cutting the welded part 140.

前後方向可理解為拉鏈80所包含之滑件60之移動方向。滑件60之前進使拉鏈80所包含之一對拉鏈鏈帶50閉合。滑件60之後退使拉鏈80所包含之一對拉鏈鏈帶50打開。在一對拉鏈鏈帶50被閉合時，各拉鏈鏈帶50所包含之拉鏈鏈齒20卡合。在一對拉鏈鏈帶50被打開時，各拉鏈鏈帶50所包含之拉鏈鏈齒20成為非卡合。The front-rear direction can be understood as the moving direction of the slider 60 included in the zipper 80. The slider 60 advances to close a pair of fastener chains 50 included in the zipper 80. The slider 60 moves backward to open one of the pair of fastener chains 50 included in the zipper 80. When a pair of fastener chains 50 is closed, the fastener elements 20 included in each fastener chain 50 are engaged. When a pair of fastener stringers 50 is opened, the fastener element 20 contained in each fastener stringer 50 becomes non-engagement.

由滑件60開閉之一對拉鏈鏈帶50沿著與前後方向正交之左右方向配置。因而，一對拉鏈鏈帶50亦能被稱為左右一對拉鏈鏈帶50。左右方向係與前後方向正交、且與拉鏈鏈帶50所包含之拉鏈帶10之第1帶面11和第2帶面12平行的任意方向。第1帶面11和第2帶面12係規定拉鏈帶10之厚度之面。上下方向係與前後方向和左右方向正交之任意方向。以下，為了詳細的敍述，參照如上述那樣定義之前後方向、左右方向以及上下方向。但是，前後方向、左右方向以及上下方向亦能夠按照以下之敍述進行再定義。The pair of fastener chains 50 opened and closed by the slider 60 are arranged in the left-right direction orthogonal to the front-rear direction. Therefore, the pair of fastener chains 50 can also be referred to as a pair of left and right fastener chains 50. The left-right direction is an arbitrary direction orthogonal to the front-rear direction and parallel to the first belt surface 11 and the second belt surface 12 of the fastener tape 10 included in the fastener tape 50. The first tape surface 11 and the second tape surface 12 define the thickness of the fastener tape 10. The up-down direction is any direction orthogonal to the front-rear direction and the left-right direction. In the following, for detailed description, reference is made to defining the front-back direction, the left-right direction, and the up-down direction as described above. However, the front-rear direction, the left-right direction, and the up-down direction can also be redefined as described below.

拉鏈80具有左右一對拉鏈鏈帶50和滑件60。各拉鏈鏈帶50具有拉鏈帶10和拉鏈鏈齒20。拉鏈80、拉鏈鏈帶50、拉鏈帶10以及拉鏈鏈齒20分別沿著前後方向延伸，在前後方向上係縱長的。拉鏈80之寬度W80與左側的拉鏈帶10之寬度W10、右側的拉鏈帶10之寬度W10以及在左右的拉鏈帶10之間沿著前後方向延伸之狹縫89之寬度W89的合計值相等。拉鏈80、拉鏈鏈帶50以及拉鏈帶10在前後方向上具有相等的長度。The zipper 80 has a pair of left and right zipper chain belts 50 and sliders 60. Each fastener chain 50 has a fastener tape 10 and a fastener element 20. The slide fastener 80, the fastener stringer 50, the fastener tape 10, and the fastener element 20 each extend along the front-back direction, and are elongated in the front-back direction. The width W80 of the zipper 80 is equal to the total of the width W10 of the left fastener tape 10, the width W10 of the right fastener tape 10, and the width W89 of the slit 89 extending in the front-rear direction between the left and right fastener tapes 10. The zipper 80, the zipper chain tape 50, and the zipper tape 10 have the same length in the front-rear direction.

拉鏈帶10係具有撓性之機織物或針織物，或者具有機織組織和針織組織組合而成之組織。拉鏈帶10具有規定拉鏈帶10之厚度的第1帶面11和第2帶面12。參照如上述那樣定義之上下方向而第1帶面11能被稱為帶下表面，第2帶面12能被稱為帶上表面。拉鏈鏈齒20設置於拉鏈帶10之第1帶面11側，並設置於拉鏈帶10之側緣部13。供拉鏈鏈齒20設置的拉鏈帶10之側緣部13係沿著拉鏈帶10之長度方向延伸的拉鏈帶10之一個側緣部。在拉鏈80中，各拉鏈鏈帶50之拉鏈帶10之側緣部13沿著左右方向相鄰地配置。同樣，在拉鏈80中，各拉鏈鏈帶50之拉鏈鏈齒20沿著左右方向相鄰地配置。The zipper tape 10 is a flexible woven fabric or knitted fabric, or has a combination of a woven structure and a knitted structure. The fastener tape 10 has a first tape surface 11 and a second tape surface 12 that define the thickness of the fastener tape 10. The first belt surface 11 can be referred to as a belt lower surface, and the second belt surface 12 can be referred to as a belt upper surface with reference to the definition of the upper and lower directions as described above. The fastener element 20 is provided on the first belt surface 11 side of the fastener tape 10 and on the side edge portion 13 of the fastener tape 10. The side edge portion 13 of the fastener tape 10 provided with the fastener element 20 is one side edge portion of the fastener tape 10 extending along the longitudinal direction of the fastener tape 10. In the slide fastener 80, the side edge portions 13 of the fastener tape 10 of each fastener tape 50 are arranged adjacent to each other in the left-right direction. Similarly, in the slide fastener 80, the fastener elements 20 of each fastener tape 50 are arranged adjacent to each other in the left-right direction.

作為選項，拉鏈80亦具有用於阻止滑件60之前進的前擋件71、及/或用於阻止滑件60之後退的後擋件72。前擋件71及/或後擋件72係金屬製或樹脂製的。在一些情況下，前擋件71具有：主體部，其配置於拉鏈帶10之第2帶面12；多個爪，其用於將拉鏈鏈齒20相對於拉鏈帶10之第1帶面11壓緊。爪在貫通拉鏈帶10後被塑性變形。後擋件72並不限於用於固著左右的拉鏈鏈齒20，亦能係能夠左右分離的後擋件。As an option, the zipper 80 also has a front stopper 71 for preventing the slider 60 from advancing, and/or a rear stopper 72 for preventing the slider 60 from retreating. The front stopper 71 and/or the rear stopper 72 are made of metal or resin. In some cases, the front stopper 71 has a main body portion arranged on the second belt surface 12 of the zipper tape 10 and a plurality of claws for positioning the zipper element 20 with respect to the first belt surface 11 of the zipper tape 10 Press tightly. The claw is plastically deformed after passing through the fastener tape 10. The rear stopper 72 is not limited to fix the left and right fastener elements 20, but can also be a rear stopper that can be separated left and right.

滑件60係金屬製或樹脂製的。滑件60具有上翼板、下翼板、將上翼板和下翼板連結之連結柱、以及凸緣部。滑件60具有一個後口和以隔著沿著上下方向延伸之連結柱之方式定位的左右一對前口。隨著滑件60之前進，左側的拉鏈鏈齒20經由左側的前口進入滑件60內，右側的拉鏈鏈齒20經由右側的前口進入滑件60內。隨著滑件60之前進，進入至滑件60內之拉鏈鏈齒20在滑件60內卡合，經由滑件60之後口露出至滑件60外。亦同樣地理解由於滑件60之後退而拉鏈鏈齒20之卡合被解除的情況，省略冗長的說明。The slider 60 is made of metal or resin. The slider 60 has an upper wing plate, a lower wing plate, a connecting column connecting the upper wing plate and the lower wing plate, and a flange portion. The slider 60 has a rear port and a pair of left and right front ports positioned so as to interpose a connecting column extending in the vertical direction. As the slider 60 advances, the left zipper element 20 enters the slider 60 through the left front port, and the right zipper element 20 enters the slider 60 through the right front port. As the slider 60 advances, the zipper teeth 20 that have entered the slider 60 are engaged in the slider 60, and the mouth is exposed to the outside of the slider 60 after passing through the slider 60. In the same way, it is understood that the slider 60 is retracted and the engagement of the fastener element 20 is released, and the redundant description is omitted.

如圖2和圖3所示，拉鏈鏈齒20包括第1區域21以及在沿著拉鏈帶10之長度方向上的拉鏈帶10之末端19與第1區域21之間的範圍內設置的第2區域22。第1區域21係單絲23以拉鏈鏈齒20具有第1腿部31、卡合頭部33、第2腿部32、以及翻轉部34之反覆構造之方式沿著拉鏈帶10之長度方向呈螺旋狀延伸的區域。另一方面，如圖4所示，第2區域22係拉鏈鏈齒20所包含之多個第1腿部31和多個第2腿部32與結合部40結合起來的區域，該結合部40含有與單絲23相同之樹脂材料。結合部40在第1區域21所包含之卡合頭部33與拉鏈帶10之末端19之間延伸。第1腿部31及/或第2腿部32具有露出之自由端部的情況被避免或抑制。在第1腿部31及/或第2腿部32具有露出之自由端部的情況下，例如有可能對人之肌膚帶來刺激，或者有可能與衣服之纖維纏絡。As shown in FIGS. 2 and 3, the fastener element 20 includes a first region 21 and a second region provided in a range between the end 19 of the fastener tape 10 and the first region 21 along the length of the fastener tape 10 Region 22. The first region 21 is a monofilament 23 along the longitudinal direction of the fastener tape 10 such that the fastener element 20 has the first leg 31, the engaging head 33, the second leg 32, and the reversing part 34 in an inverted structure Spiral extending area. On the other hand, as shown in FIG. 4, the second area 22 is an area where the plurality of first legs 31 and the plurality of second legs 32 included in the fastener element 20 are combined with the coupling portion 40, and the coupling portion 40 Contains the same resin material as the monofilament 23. The coupling portion 40 extends between the engaging head 33 included in the first area 21 and the end 19 of the fastener tape 10. The situation where the first leg portion 31 and/or the second leg portion 32 have exposed free ends is avoided or suppressed. When the first leg portion 31 and/or the second leg portion 32 have exposed free ends, for example, they may cause irritation to human skin or may become entangled with clothing fibers.

未必限定於此，但結合部40係藉由利用針對拉鏈鏈條90中之拉鏈鏈齒20之卡合頭部33所卡合的卡合區域之一部分R33 (參照圖6)進行的超聲波焊接處理形成之焊接部140 (參照圖7)之切斷來獲得的。在該情況下，在將空間部形成於拉鏈鏈條90之際，拉鏈鏈齒20之去除部分殘存於拉鏈鏈條90之情況被避免或抑制。此外，卡合頭部33所卡合的卡合區域係卡合頭部33沿著拉鏈鏈條90之長度方向呈鋸齒狀連續地設置的區域。圖6所示之附圖標記33的鋸齒之配置表示卡合頭部33之鋸齒狀之配置。要留意的是結合部40無需在針對拉鏈鏈條90形成空間部時形成。It is not necessarily limited to this, but the coupling portion 40 is formed by ultrasonic welding using a portion R33 (refer to FIG. 6) of a part of the engagement area engaged with the engagement head 33 of the fastener element 20 in the fastener chain 90 The welding part 140 (refer to FIG. 7) is obtained by cutting. In this case, when the space portion is formed in the fastener chain 90, the removed portion of the fastener element 20 remaining in the fastener chain 90 is avoided or suppressed. In addition, the engaging area in which the engaging head 33 is engaged is an area where the engaging head 33 is continuously provided in a zigzag shape along the longitudinal direction of the fastener chain 90.

It is also assumed that the cross section of the monofilament 23 can be visually recognized in the cut surface 49 (refer to FIG. 5). The shape and size of the cross-section of the monofilament 23 that can be visually recognized in the cut surface 49 vary depending on the cutting position, the cutting angle, the degree of thermal deformation of the monofilament 23, and the like.

切斷面49沿著拉鏈帶10之側緣部13延伸、及/或在第1區域21所包含之卡合頭部33與拉鏈帶10之末端19之間延伸。切斷面49無需係與前後方向平行之面，可係隨著沿前後方向延伸而相應地向左側或右側傾斜之面。未必限定於此，切斷面49位於比第1區域21所包含之卡合頭部33靠拉鏈帶內側的位置。亦可理解為切斷面49位於比第1區域21所包含之卡合頭部33靠拉鏈帶10之側緣部13的位置。此外，拉鏈帶內側係關於第1帶面11或第2帶面12自帶面外之位置朝向帶面內之位置的方向。例如，拉鏈帶內側係自第1帶面11外之位置通過拉鏈帶10之側緣部13而朝向第1帶面11內之位置的方向。切斷面49可係平坦面或非平坦面。The cut surface 49 extends along the side edge portion 13 of the fastener tape 10 and/or between the engagement head 33 included in the first region 21 and the end 19 of the fastener tape 10. The cut surface 49 need not be a surface parallel to the front-rear direction, but may be a surface inclined to the left or right as it extends in the front-rear direction. It is not necessarily limited to this, and the cut surface 49 is located inside the fastener tape from the engaging head 33 included in the first region 21. It can also be understood that the cut surface 49 is located closer to the side edge portion 13 of the fastener tape 10 than the engaging head 33 included in the first region 21. In addition, the inner side of the fastener tape is a direction of the first tape surface 11 or the second tape surface 12 from a position outside the tape surface toward a position inside the tape surface. For example, the inside of the fastener tape is directed from the position outside the first tape surface 11 to the position inside the first tape surface 11 through the side edge portion 13 of the fastener tape 10. The cut surface 49 may be a flat surface or a non-flat surface.

Fig. 17 is a schematic diagram showing the zipper chain after the cutting part. Fig. 18 is a schematic diagram showing the zipper chain after being cut in another way.

為了製造拉鏈80，使用圖8所示之拉鏈鏈條90。拉鏈鏈條90係一對拉鏈鏈帶50結合而成的。為了將拉鏈鏈條90所包含之一對拉鏈鏈齒20***滑件60，在拉鏈鏈條90設置有空間部，該空間部係在拉鏈鏈條90之長度方向上拉鏈鏈齒20被局部地去除而成的。在空間部處將拉鏈鏈條90切斷，將拉鏈鏈條90所包含之一對拉鏈鏈齒20***滑件60。空間部在將拉鏈鏈條90向下游側輸送之過程中以恆定間隔形成於拉鏈鏈條90。為了輸送拉鏈鏈條90，能使用一對輥，該一對輥將拉鏈鏈條90夾在其之間。在拉鏈鏈條90之輸送方向上，在最下游位置之空間部之一個上游側的空間部處將拉鏈鏈條90切斷。如此自拉鏈鏈條90獲得拉鏈80。In order to manufacture the zipper 80, the zipper chain 90 shown in FIG. 8 is used. The zipper chain 90 is formed by combining a pair of zipper chain belts 50. In order to insert a pair of zipper teeth 20 included in the zipper chain 90 into the slider 60, the zipper chain 90 is provided with a space portion formed by partially removing the zipper teeth 20 in the length direction of the zipper chain 90 of. At the space portion, the fastener chain 90 is cut, and a pair of fastener elements 20 included in the fastener chain 90 is inserted into the slider 60. The space is formed in the fastener chain 90 at a constant interval while conveying the fastener chain 90 to the downstream side. In order to convey the zipper chain 90, a pair of rollers can be used which sandwich the zipper chain 90 therebetween. In the conveying direction of the zipper chain 90, the zipper chain 90 is cut at a space portion on the upstream side of one of the space portions at the most downstream position. The zipper 80 is obtained from the zipper chain 90 in this way.

在將空間部形成於拉鏈鏈條90之際，如圖9所示，進行針對拉鏈鏈條90之各拉鏈鏈帶50所包含之拉鏈鏈齒20之卡合頭部33所卡合的卡合區域之一部分R33的超聲波焊接處理(參照圖6)。由此，如圖10所示，在拉鏈鏈條90形成沿著拉鏈鏈條90之長度方向延伸之焊接部140 (參照圖7)。When the space portion is formed in the zipper chain 90, as shown in FIG. 9, the engaging area engaged with the engaging head 33 of the zipper element 20 included in each zipper tape 50 of the zipper chain 90 is performed Ultrasonic welding process of a part of R33 (refer to FIG. 6). As a result, as shown in FIG. 10, the welded part 140 extending along the longitudinal direction of the fastener chain 90 is formed in the fastener chain 90 (see FIG. 7 ).

在超聲波焊接處理之際使用超聲波焊接裝置121。超聲波焊接裝置121包括砧122和變幅桿123。變幅桿123將振動能量向卡合頭部33所卡合的卡合區域之一部分R33傳遞。作為結果，存在於卡合區域之一部分R33的卡合頭部33、第1腿部31、或第2腿部32熔融，接下來，相互固著而形成焊接部140 (參照圖7)。在一些情況下，焊接部140具有同與變幅桿123之接觸相應的凹部147。The ultrasonic welding device 121 is used during the ultrasonic welding process. The ultrasonic welding device 121 includes an anvil 122 and a horn 123. The horn 123 transmits vibration energy to a part R33 of the engaging region where the engaging head 33 is engaged. As a result, the engaging head portion 33, the first leg portion 31, or the second leg portion 32 existing in a portion R33 of the engaging area are melted, and then fixed to each other to form a welded portion 140 (see FIG. 7). In some cases, the welding part 140 has a recess 147 corresponding to the contact of the horn 123.

接著，如圖11~圖13所示，進行在焊接部140形成沿著拉鏈鏈條90之長度方向延伸之切斷線SL140的工序。使用在焊接部140形成沿著拉鏈鏈條90之長度方向延伸之切斷線SL140之第1切斷裝置126。第1切斷裝置126具有刀引導件127和被刀引導件127引導之刀128。作為選項，第1切斷裝置126亦具有對移動中之拉鏈鏈條90進行引導之鏈條引導件113。Next, as shown in FIGS. 11 to 13, a process of forming a cut line SL140 extending in the longitudinal direction of the fastener chain 90 at the welded part 140 is performed. The first cutting device 126 that forms the cutting line SL140 extending along the longitudinal direction of the fastener chain 90 at the welded portion 140 is used. The first cutting device 126 includes a knife guide 127 and a knife 128 guided by the knife guide 127. As an option, the first cutting device 126 also has a chain guide 113 that guides the moving zipper chain 90.

刀引導件127和刀128一起下降。在刀引導件127接觸到拉鏈帶10之後，刀128進一步下降。在一些情況下，刀128經由在一對拉鏈帶10之間沿著拉鏈鏈條90之長度方向延伸之狹縫89到達焊接部140。換言之，刀128以經由拉鏈鏈條90所包含之各拉鏈帶10之間的狹縫89到達焊接部140之方式運動。避免或抑制了焊接部140之切斷位置之變動。The knife guide 127 and the knife 128 are lowered together. After the knife guide 127 contacts the zipper tape 10, the knife 128 is further lowered. In some cases, the knife 128 reaches the welded portion 140 via a slit 89 that extends along the length of the zipper chain 90 between the pair of zipper tapes 10. In other words, the knife 128 moves so as to reach the welded portion 140 via the slit 89 between each fastener tape 10 included in the fastener chain 90. The change of the cutting position of the welding part 140 is avoided or suppressed.

刀128係薄板狀的。刀128具有與拉鏈鏈條90之輸送方向正交的寬度W128和沿著拉鏈鏈條90之輸送方向的長度L128。在刀引導件127設置有與此類刀128之形狀匹配的通路。刀引導件127對與拉鏈鏈條90之輸送方向正交之方向上的刀128之移位進行限制，追加性地或替代性地對沿著拉鏈鏈條90之輸送方向之刀128之移位進行限制。在被刀128切斷後之焊接部140形成有切斷線SL140 (參照圖15)。切斷線SL140將焊接部140完全或局部地切斷。切斷線SL140能係貫通焊接部140之狹縫。The knife 128 is a thin plate. The knife 128 has a width W128 orthogonal to the transport direction of the zipper chain 90 and a length L128 along the transport direction of the zipper chain 90. The knife guide 127 is provided with a passage matching the shape of such a knife 128. The knife guide 127 restricts the displacement of the knife 128 in a direction orthogonal to the conveying direction of the zipper chain 90, and additionally or alternatively restricts the displacement of the knife 128 along the conveying direction of the zipper chain 90 . A cut line SL140 (see FIG. 15) is formed in the welded part 140 cut by the knife 128. The cutting line SL140 completely or partially cuts the welding part 140. The cutting line SL140 can pass through the slit of the welding part 140.

在一些情況下，刀128包括具有第1刀尖133之第1刃部分131以及具有第2刀尖134之第2刃部分132，至少兩個傾斜刃區域135、136在第1刀尖133與第2刀尖134之間延伸。在刀128到達焊接部140時，焊接部140被第1刃部分131和第2刃部分132向相反方向按壓，因而，抑制了焊接部140之不希望的或不被容許的移位。傾斜刃區域135、136所成之角能係30°以上且120°以下。第1刃部分131和第2刃部分132配置於拉鏈鏈條90之輸送方向上。同樣，第1刀尖133、第1傾斜刃區域135、第2傾斜刃區域136以及第2刀尖134配置於拉鏈鏈條90之輸送方向上。In some cases, the knife 128 includes a first blade portion 131 having a first blade tip 133 and a second blade portion 132 having a second blade tip 134, and at least two inclined blade regions 135, 136 are located at the first blade tip 133 and The second blade tip 134 extends between. When the knife 128 reaches the welding portion 140, the welding portion 140 is pressed in the opposite direction by the first blade portion 131 and the second blade portion 132, thus suppressing undesirable or unacceptable displacement of the welding portion 140. The angle formed by the inclined blade regions 135 and 136 can be 30° or more and 120° or less. The first blade portion 131 and the second blade portion 132 are arranged in the transport direction of the fastener chain 90. Similarly, the first blade edge 133, the first inclined blade area 135, the second inclined blade area 136, and the second blade edge 134 are arranged in the transport direction of the fastener chain 90.

接著，如圖16所示，沿著與拉鏈鏈條90之長度方向正交之寬度方向以伴隨著焊接部140之切斷之方式將拉鏈鏈條90切斷。為了沿著與拉鏈鏈條90之長度方向正交之寬度方向以伴隨著焊接部140之切斷之方式切斷拉鏈鏈條90，使用第2切斷裝置(未圖示)。拉鏈鏈條90例如沿著圖16之切斷線CL19被切斷。此時，焊接部140亦被切斷。如圖17和圖18所示，拉鏈鏈條90之末端19能根據切斷線CL19取得直線或鋸齒等等之任意線形狀。未必限定於此，但在切斷線SL140形成至焊接部140之後，拉鏈鏈條90被切斷。Next, as shown in FIG. 16, along the width direction orthogonal to the longitudinal direction of the fastener chain 90, the fastener chain 90 is cut along with the cutting of the welded portion 140. A second cutting device (not shown) is used to cut the zipper chain 90 along the width direction orthogonal to the longitudinal direction of the zipper chain 90 so as to be cut by the welded portion 140. The fastener chain 90 is cut along the cutting line CL19 of FIG. 16, for example. At this time, the welding part 140 is also cut. As shown in FIG. 17 and FIG. 18, the end 19 of the zipper chain 90 can take an arbitrary line shape such as a straight line or a saw tooth according to the cutting line CL19. It is not necessarily limited to this, but after the cutting line SL140 is formed to the welding part 140, the fastener chain 90 is cut.

圖17所示之拉鏈鏈條90之拉鏈鏈齒20接下來穿過被保持至保持件之滑件60。未必限定於此，為了其目的，使用用於把持拉鏈鏈條90之各拉鏈鏈帶50之夾具。反覆進行空間部之形成、拉鏈鏈條90之切斷以及使拉鏈鏈齒20穿過滑件60，自一個拉鏈鏈條90製造多個拉鏈80。對於前擋件71、後擋件72向拉鏈80之安裝，在使拉鏈鏈齒20穿過滑件60的工序之後進行。The fastener element 20 of the fastener chain 90 shown in FIG. 17 then passes through the slider 60 held to the holder. It is not necessarily limited to this, and for its purpose, a jig for holding each fastener chain 50 of the fastener chain 90 is used. The formation of the space portion, the cutting of the zipper chain 90 and the passing of the zipper chain teeth 20 through the slider 60 are repeated to manufacture a plurality of zipper 80 from one zipper chain 90. The front stopper 71 and the rear stopper 72 are attached to the slide fastener 80 after the process of passing the slide fastener element 20 through the slider 60.
