Non-adhesive portions (42) through which the texture of a tape base material (21) is exposed are provided in part of an adhesive layer (4) formed across essentially the whole of one surface of the tape base material (21) in such a way as to be confined within the adhesive layer (4).

Description

粘着テープロールおよびその製造方法Adhesive tape roll and method for producing the same
　本発明は，粘着面が表側を向くように巻回された清掃用の粘着テープロールに関し、さらに詳しく言えば、粘着剤の使用量を減らして低コストで生産可能な粘着テープロールに関する。 The present invention relates to a cleaning adhesive tape roll wound with its adhesive surface facing the front side, and more specifically, relates to an adhesive tape roll that can be produced at low cost by reducing the amount of adhesive used.
　清掃用の粘着テープロールは、シート状の基材の一方の面に粘着剤層が形成された粘着面を表側を向くようにロール状に巻回したものからなり、カーペットなどの被清掃面上で粘着テープロールを転がすことによって、被清掃面上のゴミを粘着面で補足するようにしている。 An adhesive tape roll for cleaning consists of an adhesive surface with an adhesive layer formed on one side of a sheet-like base material, wound in a roll shape so that it faces the front side. The dust on the surface to be cleaned is captured by the adhesive surface by rolling the adhesive tape roll.
　今までの粘着テープロールの多くは、基材のほぼ全面にわたって均一な厚さで粘着剤が塗布された、いわゆるベタ塗りされたタイプの粘着テープロールである。ベタ塗りタイプの粘着テープロールは、床面との接触面積が広いため、全面でゴミを捕捉できるという利点がある。 Many of the conventional adhesive tape rolls are so-called solid-coated adhesive tape rolls in which an adhesive is applied with a uniform thickness over almost the entire surface of the substrate. Since the solid-coated adhesive tape roll has a large contact area with the floor surface, there is an advantage that dust can be captured over the entire surface.
　その反面、全面に粘着剤層が均一に形成されているため、テープをロール状に巻回したときに、テープが硬く、床面にある微細な凹凸に柔軟に追従することができず、小さな石などが付着すると、その周囲の部分の粘着面が浮いてしまって、ゴミの捕捉力が低下してしまう問題があった。 On the other hand, since the pressure-sensitive adhesive layer is uniformly formed on the entire surface, when the tape is wound in a roll shape, the tape is hard and cannot follow the fine unevenness on the floor surface flexibly and is small. When stones or the like adhere, there is a problem that the adhesive surface of the surrounding portion floats and the dust capturing power is reduced.
　そこで、ベタ塗りタイプの粘着テープロールの欠点を解消したスジ塗りタイプの粘着テープロールが新たに開発された。すなわち、例えば特許文献１に示すように、スジ塗りタイプの粘着テープロールは、粘着剤層と未粘着剤層とを基材の巻回方向に沿って交互にスジ状に配置したものからなる。 Therefore, a streaked-type adhesive tape roll that eliminates the drawbacks of the solid-type adhesive tape roll was newly developed. That is, for example, as shown in Patent Document 1, a streaked-type pressure-sensitive adhesive tape roll is formed by alternately arranging pressure-sensitive adhesive layers and non-pressure-sensitive adhesive layers along the winding direction of a substrate.
　これによれば、粘着剤層がスジ状に形成されていることにより、粘着剤層のない部分が空隙となって、クッション性を生み出すため、床面の微少な凹凸に柔軟に追従し、床面のゴミを大小関係なく捕らえることができる。 According to this, since the pressure-sensitive adhesive layer is formed in a streak shape, the portion without the pressure-sensitive adhesive layer becomes a gap and creates cushioning properties. You can catch the garbage on the surface regardless of the size.

　しかしながら、この種の粘着テープロールには、以下のような課題が残されている。すなわち、昨今の急速な原油価格の高騰によって基材用のパルプや粘着剤原料など粘着テープロールを生産するための材料コストが上昇している。 However, the following problems remain in this type of adhesive tape roll. That is, the material cost for producing pressure-sensitive adhesive tape rolls such as pulp for base materials and pressure-sensitive adhesive materials has increased due to the recent rapid rise in crude oil prices.
　したがって、基材の全面に粘着剤層を形成するベタ塗りタイプの粘着テープロールは、粘着剤の塗布面積が大きいため、材料コストが高い。他方において、スジ塗りタイプは、未粘着部があるため、塗布量は少ないように思われがちだが、未粘着部の形成に伴う捕捉性の低下を補うため、ベタ塗りよりも粘着剤層が厚塗りに形成されており、材料コストは、ベタ塗りとさほど変わりない。 Therefore, a solid coating type adhesive tape roll in which an adhesive layer is formed on the entire surface of the base material has a high material cost because the adhesive application area is large. On the other hand, the streaked coating type has a non-adhesive part, so it seems that the coating amount is small, but the adhesive layer is thicker than the solid coating in order to compensate for the lowering of the trapping property due to the formation of the non-adhesive part The material cost is not much different from solid coating.
　そこで、本発明は、上述した課題を解決するため、ゴミの捕捉性を落とすことなく、粘着剤の使用量を減らして低コストで生産可能な粘着テープロールを提供することにある。 Therefore, in order to solve the above-described problems, the present invention is to provide an adhesive tape roll that can be produced at a low cost by reducing the amount of the adhesive used without reducing the dust capturing ability.
　上述した目的を達成するため、本発明は以下に示すいくつかの特徴を備えている。請求項１に記載の発明は、基材の一方の面に粘着剤層が形成された粘着テープを、粘着面が外側を向くようにしてロール状に巻回される粘着テープロールにおいて、上記粘着剤層は、単一の粘着剤からなる単層構造であって、上記基材の地肌が露出する未粘着部を含んで上記基材の一方の面のほぼ全面にわたって設けられていることを特徴としている。 In order to achieve the above-described object, the present invention has several features described below. The invention according to claim 1 is a pressure-sensitive adhesive tape roll in which a pressure-sensitive adhesive tape having a pressure-sensitive adhesive layer formed on one surface of a substrate is wound in a roll shape with the pressure-sensitive adhesive surface facing outward. The agent layer has a single-layer structure composed of a single adhesive, and is provided over almost the entire surface of one side of the base material, including an unadhesive portion where the background of the base material is exposed. It is said.

　図１～図３に示すように、この粘着テープロール１は、テープ基材２１の一方の面にゴミ取り面２２が形成された粘着テープ２を有し、そのゴミ取り面２２が表側（図１では上面側）を向くように巻芯３に沿ってロール状に巻回したものからなる。 As shown in FIGS. 1 to 3, this adhesive tape roll 1 has an adhesive tape 2 having a dust removal surface 22 formed on one surface of a tape substrate 21, and the dust removal surface 22 is on the front side (FIG. 1). 1 is formed by winding in a roll shape along the core 3 so as to face the upper surface side).
　この例において、巻芯３はボール紙などの紙製巻芯が用いられているが、これ以外に合成樹脂製の巻芯を用いてもよい。さらには、巻芯３を用いずに巻回する、いわゆるコアレス構造であってもよく、本発明において巻芯３の構成は任意である。 In this example, a paper core such as cardboard is used as the core 3, but a synthetic resin core may also be used. Furthermore, a so-called coreless structure in which the winding core 3 is wound without using the winding core 3 may be used. In the present invention, the configuration of the winding core 3 is arbitrary.
　粘着テープ２のゴミ取り面２２を挟んで幅方向の両端には、未粘着部としてのドライエッジ部２４，２４が設けられているが、本発明において、ドライエッジ部２４，２４は任意的な構成要素である。 Dry edge portions 24 and 24 as non-adhesive portions are provided at both ends in the width direction across the dust removal surface 22 of the adhesive tape 2, but in the present invention, the dry edge portions 24 and 24 are optional. It is a component.
　テープ基材２１は、例えば紙製で裏面（図３では下面）には、テープ基材２１の補強および剥離用としてのラミネートフィルム２３が設けられている。この例において、ラミネートフィルム２３は、ポリエチレン製でテープ基材２１の裏面に一体的に貼り合わせられている。テープ基材２１の材質は、仕様に応じて任意に選択されて良い。 The tape base material 21 is made of, for example, paper, and a laminate film 23 for reinforcing and peeling the tape base material 21 is provided on the back surface (lower surface in FIG. 3). In this example, the laminate film 23 is made of polyethylene and is integrally bonded to the back surface of the tape base material 21. The material of the tape base material 21 may be arbitrarily selected according to specifications.
　本発明において、ラミネートフィルム２３は任意的な構成要素であり、テープ基材２１を紙に代えて、樹脂フィルムなどを用いることにより不要とすることができる。また、粘着剤の組成をコントロールすることによっても、ラミネートフィルム２３を省くことができる。 In the present invention, the laminate film 23 is an optional component, and can be made unnecessary by using a resin film or the like instead of the tape substrate 21 with paper. Also, the laminate film 23 can be omitted by controlling the composition of the pressure-sensitive adhesive.
　ゴミ取り面２２は、基材２１に沿って形成された粘着剤層４によって構築されている。粘着剤層４は、例えばＳＩＳ（スチレン－イソプレン－スチレン）系などの粘着剤をテープ基材２１の表面に沿って一様に塗布してなる単一層である。 The dust collecting surface 22 is constructed by the pressure-sensitive adhesive layer 4 formed along the base material 21. The pressure-sensitive adhesive layer 4 is a single layer in which a pressure-sensitive adhesive such as SIS (styrene-isoprene-styrene) is applied uniformly along the surface of the tape substrate 21.
　粘着剤層４は、テープ基材２１に沿って所定厚さに均一に塗布されたベース層４１を備えている。この第１実施形態において、ベース層４１の厚さｔ１は１５μｍである。ベース層４１の一部には、未粘着部４２が一体的に形成されている。 The pressure-sensitive adhesive layer 4 includes a base layer 41 that is uniformly applied to a predetermined thickness along the tape base material 21. In the first embodiment, the thickness t1 of the base layer 41 is 15 μm. A non-adhesive portion 42 is integrally formed on a part of the base layer 41.
　未粘着部４２は、粘着テープ２の幅方向（図２では左右方向）に沿って所定間隔で多数形成された点状（ドット状）であり、底部が基材２１の地肌が露出するように形成されている。この実施形態では、直径φ１：３ｍｍの円柱状に形成されている。 The non-adhesive part 42 is a dot-like (dot shape) formed at a predetermined interval along the width direction (left-right direction in FIG. 2) of the adhesive tape 2 so that the bottom of the base 21 is exposed. Is formed. In this embodiment, it is formed in a cylindrical shape having a diameter of φ1: 3 mm.
　図２に示すように、この例において、未粘着部４２は、幅方向（図２では左右方向）と巻回方向（図２では上下方向）に沿って、それぞれ一定の間隔で格子状に規則的に配置されているが、図４に示すように、千鳥状に配置されてもよい。 As shown in FIG. 2, in this example, the non-adhesive portions 42 are regularly arranged in a lattice pattern at regular intervals along the width direction (left-right direction in FIG. 2) and the winding direction (up-down direction in FIG. 2). However, as shown in FIG. 4, they may be arranged in a staggered manner.
　粘着テープ２には、所定の間隔で切断用の切れ目５が設けられている。この例において、切れ目５は、周長にして３６０°未満となる間隔で粘着テープ２の巻回方向に対して直行する方向に形成されたミシン目からなるが、本発明において切れ目５の具体的な構成は任意であって良い。 The adhesive tape 2 is provided with cuts 5 for cutting at predetermined intervals. In this example, the cut 5 is a perforation formed in a direction perpendicular to the winding direction of the pressure-sensitive adhesive tape 2 at an interval that is less than 360 ° in circumferential length. The configuration may be arbitrary.
　図５を参照して、本発明の第２実施形態に係る粘着テープロールについて説明するが、この第２実施形態の粘着テープロール１ａの基本的な構成は、上述した第１実施形態と同じであるため、同一もしくは同一と見なされる箇所には同じ参照符号を付す。 The adhesive tape roll according to the second embodiment of the present invention will be described with reference to FIG. 5, but the basic configuration of the adhesive tape roll 1a of the second embodiment is the same as that of the first embodiment described above. For this reason, parts that are considered to be the same or the same are given the same reference numerals.
　この粘着テープロール１ａは、粘着テープ２の繰り出し方向に沿って所定の角度θで傾斜された点線状の第１未粘着部４３と、第１未粘着部４３に沿って平行に配置された線状の第２未粘着部４４とが粘着剤層４内に残されるように設けられている。 The pressure-sensitive adhesive tape roll 1 a includes a dotted first unadhesive portion 43 that is inclined at a predetermined angle θ along the feeding direction of the pressure-sensitive adhesive tape 2, and a line that is disposed in parallel along the first non-adhesive portion 43. The second unadhered portion 44 is provided so as to remain in the adhesive layer 4.
　第１未粘着部４３は、点状の未粘着部を斜め方向に沿って一定の間隔ｄで多数配置した点線状に形成されており、この例において、第１未粘着部４３は、直径２．０ｍｍの点状の未粘着部が、間隔ｄが２．０ｍｍで一列となるように配置されている。 The first non-adhesive portion 43 is formed in a dotted line shape in which a large number of dot-like non-adhesive portions are arranged at a constant interval d along an oblique direction. In this example, the first non-adhesive portion 43 has a diameter of 2 0.0 mm point-shaped non-adhesive portions are arranged in a line with a distance d of 2.0 mm.
　第２未粘着部４４は、幅１．５ｍｍの線状に形成されており、この例において、角度θが３０°となるように設けられている。第２未粘着部４４の幅および角度θは、仕様に応じて任意に変更できる。 The second non-adhesive portion 44 is formed in a linear shape having a width of 1.5 mm, and in this example, is provided so that the angle θ is 30 °. The width and angle θ of the second unadhered portion 44 can be arbitrarily changed according to the specifications.
　第１未粘着部４３および第２未粘着部４４は、粘着テープ２の幅方向（図５では左右方向）に沿って間隔Ｐをもって繰り返し配置されている。この例において、間隔Ｐは、６５ｍｍであるが、その配置間隔Ｐは仕様に応じて任意に設定されて良い。 The first non-adhesive part 43 and the second non-adhesive part 44 are repeatedly arranged with an interval P along the width direction of the adhesive tape 2 (the left-right direction in FIG. 5). In this example, the interval P is 65 mm, but the arrangement interval P may be arbitrarily set according to the specification.
　第１未粘着部４３と第２未粘着部４４は、切れ目５に沿って粘着テープ２を切断した際に、粘着テープの先端に形成される各未粘着部４３，４４と、粘着テープの先端の下に重なり合う次層の粘着テープ２に形成される未粘着部４３，４４とが重なり合わないように設定されている。 The first non-adhesive portion 43 and the second non-adhesive portion 44 are formed at the tip of the adhesive tape when the adhesive tape 2 is cut along the cut 5, and the tip of the adhesive tape. It is set so that the non-adhesive parts 43 and 44 formed in the adhesive tape 2 of the next layer that overlaps the upper part of the adhesive tape do not overlap.
　これによれば、粘着テープ２の端部と次層の粘着テープ２との重なり部分での各未粘着部４３，４４が重なり合わないため、使用済みの再外層の粘着テープ２の端部を簡単に判別できるため、テープ端部を捲り易くなる。 According to this, since each non-adhesive part 43,44 in the overlap part of the edge part of the adhesive tape 2 and the adhesive tape 2 of the next layer does not overlap, the edge part of the adhesive tape 2 of the used outer layer is used. Since it can be easily discriminated, the tape end portion is easily wound.
　また、図５を参照して、第１未粘着部４３が角度θで傾斜させた場合、「ａ」を起点とした第１未粘着部４３は、テープ周長Ｌ分先では「ｂ」に移動する。すなわち、このｂ点における粘着テープ２の幅方向の距離をＸとすると、Ｘ＝ｔａｎθ×Ｌで表される。 Referring to FIG. 5, when the first non-adhesive portion 43 is inclined at an angle θ, the first non-adhesive portion 43 starting from “a” is set to “b” at the tape circumferential length L. Moving. That is, when the distance in the width direction of the adhesive tape 2 at the point b is X, X = tan θ × L.
　一方、第１未粘着部４３と第２未粘着部４４の繰り出し方向の間隔Ｐを決めるとき、Ｐ＝Ｘであるとロール状にした場合、ａ’点とｂ点とが重なり合い、めくり口が判別しにくくなるため、Ｐ≠Ｘとなるようにすることが好ましい。 On the other hand, when determining the distance P in the feed-out direction of the first non-adhesive part 43 and the second non-adhesive part 44, when P = X, when the roll is formed, the points a 'and b overlap and the turning mouth is Since it becomes difficult to discriminate, it is preferable that P ≠ X.
　さらに、粘着テープロールの最大外径時のテープ長さと、最小外径時のテープ長さは異なるため、この点をさらに考慮してａ’点とｂ点とが重なり合わないようにすることが好ましい。 Furthermore, since the tape length at the maximum outer diameter of the adhesive tape roll is different from the tape length at the minimum outer diameter, this point may be further taken into consideration so that the points a ′ and b do not overlap. preferable.
　その具体例の一例を示すと、使用開始時（最大外径時）の粘着テープの１周長長さＬｍａｘは、外径６０ｍｍの場合、Ｌｍａｘ＝６０×３．１４＝１８８ｍｍであり、終了時（最小外径時）の粘着テープの１周長長さＬｍｉｎは、巻芯外径４０の場合、Ｌｍｉｎ＝４０×３．１４＝１２６ｍｍとなる。 As an example of the specific example, the one-round length Lmax of the adhesive tape at the start of use (at the maximum outer diameter) is Lmax = 60 × 3.14 = 188 mm when the outer diameter is 60 mm, and at the end (minimum) In the case of the core outer diameter 40, the circumference length Lmin of the adhesive tape at the outer diameter is Lmin = 40 × 3.14 = 126 mm.
　この条件で角度θ＝３０°で未粘着部を形成した場合、Ｘｍａｘ＝ｔａｎ３０°×１８８＝１０９ｍｍとなり、Ｘｍｉｎ＝ｔａｎ３０°×１２６＝７３ｍｍとなる。したがって、Ｐは７３ｍｍと１０９ｍｍと、その約数と倍数以外を設定するようにすればよい。 When an unadhered part is formed at an angle θ = 30 ° under these conditions, Xmax = tan 30 ° × 188 = 109 mm and Xmin = tan 30 ° × 126 = 73 mm. Therefore, P may be set to 73 mm and 109 mm, other than divisors and multiples thereof.
　なお、角度θは仕様に応じて任意の角度に設定でき、上記のように角度に応じたＸ値を見て、妥当なＰ値を決定すればよい。ただし、Ｐ値が小さすぎると、未粘着部の斜線本数および間隔が狭くなりすぎてしまい、ａ’点とｂ点が重なりやすくなり好ましくない。逆にＰ値が大きすぎた場合、未粘着部の斜線本数が少なくなり、めくり口の判別がしにくくなるため好ましくない。したがって、未粘着部の基端ａ，ａ’，ａ”がテープ幅Ｗに対して２，３箇所となるようにＰ値を設定することが好ましい。 The angle θ can be set to an arbitrary angle according to the specification, and an appropriate P value may be determined by looking at the X value corresponding to the angle as described above. However, if the P value is too small, the number of hatched lines and the interval between the non-adhesive portions become too small, and the points a ′ and b tend to overlap, which is not preferable. On the other hand, if the P value is too large, the number of non-adhered portions is not preferable because the number of hatched lines decreases and it becomes difficult to determine the turning mouth. Therefore, it is preferable to set the P value so that the base ends a, a ′, a ″ of the non-adhesive portion are a few places with respect to the tape width W.
　粘着テープロール１ａの粘着剤層４にはさらに、粘着テープロール１の回転方向を示す矢印マーク４５と、商品名や社名などのロゴマーク４６が未粘着部として設けられている。この例において矢印マーク４５とロゴマーク４６は、第１未粘着部４３および第２未粘着部４４の繰り返しパターンの間に所定の間隔をもって繰り返すように配置されている。 The pressure-sensitive adhesive layer 4 of the pressure-sensitive adhesive tape roll 1a is further provided with an arrow mark 45 indicating the rotation direction of the pressure-sensitive adhesive tape roll 1 and a logo mark 46 such as a product name or a company name as non-adhesive portions. In this example, the arrow mark 45 and the logo mark 46 are arranged so as to repeat with a predetermined interval between the repeated patterns of the first non-adhesive portion 43 and the second non-adhesive portion 44.
　この例において、粘着剤層４には、矢印マーク４５とロゴマーク４６が未粘着部として設けられているが、これ以外に例えば切れ目の位置を表した表示部や、残り長さや巻数などの数字などの各種表示要素を未粘着部としてもよい。 In this example, the adhesive layer 4 is provided with an arrow mark 45 and a logo mark 46 as non-adhesive parts, but in addition to this, for example, a display part indicating the position of a break, a number such as the remaining length and the number of windings, etc. Various display elements such as may be used as the non-adhesive portion.
　以下に、粘着テープの粘着剤層４の厚さと面積比との相関関係について具体的な実施例を例に挙げて説明する。まず、紙製基材（幅１５０ｍｍ）の一方の面に粘着剤層４の層厚さを１０～３５μｍの範囲内で５μｍ刻みで厚さを変え、かつ、塗工面積を４０～１００％の範囲内で変えた粘着テープを用意し、その際の回転抵抗値を以下に示す測定方法で測定した。 Hereinafter, the correlation between the thickness of the pressure-sensitive adhesive layer 4 of the pressure-sensitive adhesive tape and the area ratio will be described with reference to specific examples. First, the thickness of the pressure-sensitive adhesive layer 4 on one side of a paper substrate (width 150 mm) is changed within 5 to 10 μm within the range of 10 to 35 μm, and the coating area is 40 to 100%. The pressure-sensitive adhesive tape changed within the range was prepared, and the rotational resistance value at that time was measured by the measuring method shown below.
　回転抵抗値は、専用の測定装置を用いて行う。図９に示すように、先端に粘着テープロール１が取り付けられ、他端に抵抗計Ｒが一体的に取り付けられた治具を図示しない駆動手段を介して７２５ｍｍ／ｓｅｃにて始点Ａから終点Ｂに至る距離（８００ｍｍ）を水平移動させた際に被清掃面（カーペットＣ）との間で生じた荷重を回転抵抗値とした。その測定結果を表１に示す。 Rotational resistance is measured using a dedicated measuring device. As shown in FIG. 9, a jig having an adhesive tape roll 1 attached to the tip and an ohmmeter R integrally attached to the other end is connected from a start point A to an end point B at 725 mm / sec via a driving means (not shown). The load generated between the surface to be cleaned (carpet C) when horizontally moving the distance (800 mm) was set as the rotational resistance value. The measurement results are shown in Table 1.
　次に、表１を元に縦軸を回転抵抗値、横軸を粘着剤層厚さとしたグラフを作成した。図６に示すように、一般的な清掃用粘着テープロールの平均的な回転抵抗値（Ｄａｖｅ）は１２Ｎ／ｍｍであり、その前後±４Ｎ／ｍｍ（Ｄｍａｘ，Ｄｍｉｎ）を製品許容範囲として設定した場合、図６のスマッジングで表された箇所が使用可能領域としてモデル化できる。 Next, based on Table 1, a graph was prepared with the vertical axis representing the rotational resistance value and the horizontal axis representing the thickness of the adhesive layer. As shown in FIG. 6, the average rotational resistance value (Dave) of a general cleaning adhesive tape roll is 12 N / mm, and ± 4 N / mm (Dmax, Dmin) before and after that is set as the product allowable range. In this case, the portion represented by smudging in FIG. 6 can be modeled as an available area.
　したがって、図６にモデル化したように粘着剤層の厚さと未粘着部の面積を設定することにより、粘着剤の使用量を減らしつつも、ゴミの捕捉性能を落とさない粘着テープロールが生産できる。 Therefore, by setting the thickness of the pressure-sensitive adhesive layer and the area of the non-adhesive portion as modeled in FIG. 6, it is possible to produce a pressure-sensitive adhesive tape roll that does not deteriorate the dust capture performance while reducing the amount of pressure-sensitive adhesive used. .
　本発明の粘着テープロールの製造方法の一例について説明する。図７（ａ）に示すように、この粘着テープロールの製造装置１００は、粘着剤１１１が貯留されたリザーバ１１０と、一部が同リザーバ１１０の粘着剤１１１に浸されるように設置される転写ロール１２０と、テープ基材２１を挟んで転写ロール１２０に対向するように配置されるプレスロール１３０とを含んでいる。 An example of a method for producing the adhesive tape roll of the present invention will be described. As shown in FIG. 7A, the adhesive tape roll manufacturing apparatus 100 is installed such that a pressure-sensitive adhesive 111 is stored in a reservoir 110 and a part is immersed in the pressure-sensitive adhesive 111 in the reservoir 110. The transfer roll 120 and the press roll 130 arrange | positioned so as to oppose the transfer roll 120 on both sides of the tape base material 21 are included.
　この例において、粘着剤１１１はリザーバ１１０に貯留され、そこに転写ロール１２０を浸すことによって、粘着剤１１１が転写ロール１２０に供給されるようになっているが、図７（ｂ）に示すように、転写ロール１２０にガイドロール１４０を接触させ、転写ロール１２０とガイドロール１４０の間に形成される空間に粘着剤１１１を貯留するようにしてもよい。 In this example, the pressure-sensitive adhesive 111 is stored in the reservoir 110, and the pressure-sensitive adhesive 111 is supplied to the transfer roll 120 by immersing the transfer roll 120 therein, as shown in FIG. 7B. Alternatively, the guide roll 140 may be brought into contact with the transfer roll 120, and the adhesive 111 may be stored in a space formed between the transfer roll 120 and the guide roll 140.
　転写ロール１２０は、ロール表面にエッチング加工によって凹型面１２１が設けられた、いわゆるグラビアロールが用いられている。転写ロール１２０には、転写ロール１２０に付着した粘着剤１１１を均すとともに、余剰分を取り除くためのスキージ１５０が設けられている。 The transfer roll 120 is a so-called gravure roll having a concave surface 121 formed by etching on the roll surface. The transfer roll 120 is provided with a squeegee 150 for leveling the adhesive 111 adhering to the transfer roll 120 and removing excess.
　粘着剤層４を塗工するに当たっては、図８（ａ）に示すように、リザーバ１２０内に浸かった転写ロール１２０を回転させることにより、凹型面１２１内に粘着剤１１１が充填される。 In applying the adhesive layer 4, as shown in FIG. 8A, the concave surface 121 is filled with the adhesive 111 by rotating the transfer roll 120 immersed in the reservoir 120.
　転写ロール１２０をさらに回転させると、図８（ｂ）に示すように、転写ロール１２０の端部表面に接触したスキージ１５０によって凹型面１２１内に粘着剤１１１が行き渡らせられるとともに、はみ出しだ余剰分の粘着剤１１１が取り除かれる。 When the transfer roll 120 is further rotated, as shown in FIG. 8B, the adhesive 111 is spread in the concave surface 121 by the squeegee 150 in contact with the end surface of the transfer roll 120, and an excess portion that protrudes. The adhesive 111 is removed.
　スキージ１５０を通過した転写ロール１２０に沿ってテープ基材２１の一方の面が接触するように供給され、他方の面はガイドロール１３０によって押圧される。これにより、図８（ｃ）に示すように、凹型面１２１内に充填された粘着剤１１１がテープ基材２１に転写され、粘着剤層４のベース層４１と凸部４２とが同時に形成される。 Supplied so that one surface of the tape substrate 21 contacts along the transfer roll 120 that has passed through the squeegee 150, and the other surface is pressed by the guide roll 130. As a result, as shown in FIG. 8C, the pressure-sensitive adhesive 111 filled in the concave surface 121 is transferred to the tape base material 21, and the base layer 41 and the convex portion 42 of the pressure-sensitive adhesive layer 4 are formed simultaneously. The
