複合シートの製造方法Method of manufacturing composite sheet
　本開示は、複合シートの製造方法に関する。 The present disclosure relates to a method of manufacturing a composite sheet.
　従来、伸縮力を有する複合シートの製造方法は公知である。例えば、特許文献１には、綺麗に配列した多数の凸状部を有する伸縮力を有する複合シートの製造方法が開示されている。 Heretofore, methods for producing a composite sheet having a stretching force are known. For example, Patent Document 1 discloses a method of manufacturing a composite sheet having a stretching force having a large number of convex portions arranged neatly.
特開２００９－１６０９１９号公報JP, 2009-160919, A
　特許文献１に開示された発明に係る複合シートでは、機械方向において、伸縮力の大きい部分と、伸縮力の小さい部分とを有する複合シートを製造することが困難であった。 In the composite sheet according to the invention disclosed in Patent Document 1, it has been difficult to manufacture a composite sheet having a portion with high expansion force and a portion with low expansion force in the machine direction.
　本発明の課題は、機械方向において、伸縮力の大きい部分と、伸縮力の小さい部分とを有する複合シートを容易に製造することができる複合シートの製造方法を提供することにある。 An object of the present invention is to provide a method for producing a composite sheet capable of easily producing a composite sheet having a portion having a large stretching force and a portion having a small stretching force in the machine direction.
　本発明は、（ａ）機械方向へ搬送された第１シートに前記機械方向へ延びる連続弾性体を固定する工程と、（ｂ）前記第１シートに固定された１本の前記連続弾性体のうちの一部を前記機械方向において間隔を空けて切断する工程と、（ｃ）前記第１シートと前記第２シートとの間に前記連続弾性体を介在させた状態で前記第１シートと前記第２シートとを互いに接合する工程とを含む複合シートの製造方法に向けられる。 The present invention comprises the steps of: (a) fixing a continuous elastic body extending in the machine direction to the first sheet conveyed in the machine direction; (b) one continuous elastic body fixed to the first sheet And (c) cutting the first sheet and the second sheet while interposing the continuous elastic body between the first sheet and the second sheet. And b. Bonding the second sheet to one another.
　前記ｂ工程において、切断部分における前記連続弾性体の残存部分の前記機械方向と交差する交差方向の寸法を、切断部分を有していない前記連続弾性体の前記交差方向における寸法より小さくする。よって、連続弾性体は、切断部分において交差方向の寸法が小さくなるため、１本の連続弾性体において弾性力が大きい部分と、弾性力が小さい部分とを有することができる。このため、機械方向において、伸縮力が大きい部分と、伸縮力が小さい部分とを有する複合シートを容易に製造することができる。 In step b, the dimension in the cross direction intersecting the machine direction of the remaining portion of the continuous elastic body in the cut portion is smaller than the dimension in the cross direction of the continuous elastic body having no cut portion. Therefore, since the dimension of the cross direction in a cutting part becomes small, a continuous elastic body can have a part with large elastic power, and a part with small elastic power in one continuous elastic body. For this reason, in the machine direction, it is possible to easily manufacture a composite sheet having a portion with a large stretch force and a portion with a small stretch force.
　前記ｂ工程において、前記連続弾性体の前記交差方向における寸法よりも、前記交差方向の長さ寸法が小さい切断具で前記連続弾性体の一部と、前記連続弾性体と厚さ方向に重なる前記第１及び第２シートの少なくとも一方を切断する。このため、第１及び第２シートにおける切断部分の面積が狭い複合シートを提供することができる。 In the step b, the cutting tool having a length dimension in the cross direction smaller than the dimension in the cross direction of the continuous elastic body overlaps a portion of the continuous elastic body in the thickness direction with the continuous elastic body Cutting at least one of the first and second sheets. For this reason, it is possible to provide a composite sheet in which the area of the cut portion in the first and second sheets is narrow.
　前記ｂ工程において、前記連続弾性体の前記交差方向における寸法よりも、前記交差方向の長さ寸法が大きい切断具で前記連続弾性体の一部と、前記連続弾性体と前記厚さ方向に重なる前記第１及び第２シートの少なくとも一方と、前記連続弾性体と前記厚さ方向に重ならない前記第１及び第２シートの少なくとも一方とを切断する。このため、第１及び第２シートにおける切断部分の面積が広い複合シートを提供することができる。 In the step b, a portion of the continuous elastic body overlaps the continuous elastic body in the thickness direction with a cutting tool having a length dimension in the cross direction larger than a size in the cross direction of the continuous elastic body At least one of the first and second sheets and at least one of the first and second sheets not overlapping the continuous elastic body in the thickness direction are cut. For this reason, the composite sheet in which the area of the cutting part in the 1st and 2nd sheet is large can be provided.
　前記連続弾性体の周面に接着剤を塗布した後、前記ｃ工程において、前記接着剤によって前記連続弾性体を前記第１及び第２シートにそれぞれ固定し、前記ｃ工程後の前記ｂ工程において、前記連続弾性体の一部を前記切断具によって切断する。よって、第１シート及び第２シートに固定された連続弾性体を切断するため、連続弾性体の切断個所の精度を向上することができる。 After applying an adhesive to the circumferential surface of the continuous elastic body, the continuous elastic body is fixed to the first and second sheets by the adhesive in the step c, and the step b after the step c is performed. And a part of the continuous elastic body is cut by the cutting tool. Therefore, since the continuous elastic body fixed to the 1st sheet and the 2nd sheet is cut, the precision of the cutting part of a continuous elastic body can be improved.
　前記ｂ工程において、前記連続弾性体の前記交差方向における両側縁よりも内側において、前記連続弾性体の一部を前記切断具によって切断する。このため、連続弾性体を切断する工程において連続弾性体の切れ端が発生することがないため、複合シートに切れ端が入ることがなく、複合シートの美観を向上することができる。 In the step b, a part of the continuous elastic body is cut by the cutting tool inside the both side edges in the cross direction of the continuous elastic body. For this reason, since a cut end of the continuous elastic body is not generated in the step of cutting the continuous elastic body, the cut end does not enter the composite sheet, and the appearance of the composite sheet can be improved.
　前記切断具は、前記機械方向に対して傾斜するようにベース部に固定してある。このため、連続弾性体を切断するとき、ベース部に加わる力を機械方向へ分散することができる。 The cutting tool is fixed to the base so as to be inclined with respect to the machine direction. Therefore, when cutting the continuous elastic body, the force applied to the base can be dispersed in the machine direction.
　前記ａ工程及び前記ｃ工程後の前記ｂ工程において、前記第１及び第２シートに前記切断部分を形成し、（ｄ）前記ｂ工程後、前記第１及び第２シートの少なくとも一方に、防水性の第３シートを固定及び積層する工程を有する。このため、第１及び第２シートは切断部分を有し、通気性を有する一方、第３シートは切断部分を有していないため、防水性を維持することができ、多機能の複合シートを提供することができる。 Forming the cut portion on the first and second sheets in the step b after the steps a and c, and (d) waterproofing at least one of the first and second sheets after the step b Fixing and laminating the third sheet of elasticity. Therefore, the first and second sheets have a cut portion and are breathable, while the third sheet does not have a cut portion, so that waterproofness can be maintained, and a multifunctional composite sheet can be obtained. Can be provided.
　本発明の１つ以上の実施形態に係る複合シートの製造方法によれば、切断部分では伸縮力が小さくなる一方、非切断部分では、切断部分よりも伸縮力が大きくなるため、１本の連続弾性体が、弾性力の大きい箇所と、弾性力の小さい箇所とを有することができる。よって、本発明によれば、機械方向において、弾性力の大きい部分と、弾性力の小さい部分とを有する複合シートを容易に製造することができる。 According to the method of manufacturing a composite sheet according to one or more embodiments of the present invention, the stretch force is reduced at the cut portion, while the stretch force is greater at the non-cut portion than at the cut portion. The elastic body can have a portion having a large elastic force and a portion having a small elastic force. Therefore, according to the present invention, it is possible to easily manufacture a composite sheet having a large elastic force and a small elastic force in the machine direction.

The plurality of continuous elastic bodies 103 are spaced apart from one another in the cross direction CD, and are arranged, for example, at equal intervals.
＜切断部１３０（ｂ工程）＞
　切断部１３０は、図２に示すように、周面に複数のカッター（切断具）１３１を有する切断ローラ１３２を含む。カッター１３１は、交差方向ＣＤにおいて、ローラの周面に１０個、配置してあり、周方向において、例えば、等間隔となるように、複数個、配置してある。切断ローラ１３２の交差方向ＣＤにおけるカッター１３１の配置間隔は、連続弾性体１０３の交差方向ＣＤの間隔と同一である。 Cutting Section 130 (Step b)>
The cutting unit 130 includes a cutting roller 132 having a plurality of cutters (cutting tools) 131 on its circumferential surface, as shown in FIG. The cutter 131 is disposed ten on the circumferential surface of the roller in the cross direction CD, and a plurality of cutters 131 are disposed in the circumferential direction at equal intervals, for example. The arrangement interval of the cutters 131 in the cross direction CD of the cutting roller 132 is the same as the interval of the cross direction CD of the continuous elastic body 103.
　また、切断部１３０及び接合部１４０は、機械方向ＭＤにおいて、図２中、左方に位置する第３ローラ１３３と、図２中、右方に位置する第４ローラ１３４との一対のローラ１３３，１３４と、これらのローラ１３３，１３４にかけ渡された無端ベルト１３５とを有し、第１シート１０１及び連続弾性体１０３を押圧する押圧部１３６とを有している。第３ローラ１３３は、切断ローラ１３２の下方に配置してあり、第４ローラ１３４は、接合部１４０のローラ１４１の下方に配置してある。 Further, the cutting unit 130 and the bonding unit 140 are a pair of rollers 133 of the third roller 133 located on the left in FIG. 2 and the fourth roller 134 located on the right in FIG. 2 in the machine direction MD. 134 and an endless belt 135 passed over the rollers 133 and 134, and has a pressing portion 136 for pressing the first sheet 101 and the continuous elastic body 103. The third roller 133 is disposed below the cutting roller 132, and the fourth roller 134 is disposed below the roller 141 of the joint portion 140.
　図４は、切断部１３０において、交差方向ＣＤの連続弾性体１０３及び第１シート１０１の拡大断面図であり、図５は、切断ローラ１３２のカッター１３１の配列を示すため、切断ローラ１３２の周面を、機械方向ＭＤ及び交差方向ＣＤに展開した展開図である。カッター１３１は、切断ローラ１３２の周方向Ｒ（図５における機械方向ＭＤ）及び交差方向ＣＤにおいて、例えば、等間隔に配置してある。図４を参照すると、各カッター１３１の交差方向ＣＤにおける寸法Ｌ１１が、連続弾性体１０３の交差方向ＣＤにおける繊度の寸法（連続弾性体１０３の交差方向ＣＤにおける繊度の寸法は、連続弾性体１０３に力が加えられていない状態において測定した径）よりも小さい。よって、カッター１３１によって、１本の連続弾性体１０３のうちの一部を切断すると、連続弾性体１０３における交差方向ＣＤの中央部にはカッター１３１で切除されて切断部分１０４ａが形成され（連続弾性体１０３の交差方向ＣＤの寸法はＬ１２である）、切断部分１０４ａが存在する部分は伸縮性を喪失する一方、連続弾性体１０３における残余部分１０５は、伸縮性を維持している。 FIG. 4 is an enlarged cross-sectional view of the continuous elastic body 103 in the cross direction CD and the first sheet 101 in the cutting portion 130, and FIG. 5 shows the arrangement of the cutters 131 of the cutting roller 132. It is the expanded view which expand | deployed the surface to machine direction MD and cross direction CD. The cutters 131 are arranged at equal intervals, for example, in the circumferential direction R (the machine direction MD in FIG. 5) of the cutting roller 132 and the cross direction CD. Referring to FIG. 4, the dimension L 11 in the cross direction CD of each cutter 131 is the size of the fineness in the cross direction CD of the continuous elastic body 103 (the size of the fineness in the cross direction CD of the continuous elastic body 103 is the continuous elastic body 103). Smaller than the diameter measured when no force is applied. Therefore, when a part of one continuous elastic body 103 is cut by the cutter 131, the cut portion 104a is formed by cutting with the cutter 131 at the central part of the cross direction CD in the continuous elastic body 103 (continuous elasticity The dimension of the cross direction CD of the body 103 is L12), the portion where the cut portion 104a exists loses the stretchability, while the remaining portion 105 in the continuous elastic body 103 maintains the stretchability.
　カッター１３１によって、連続弾性体１０３を切断したとき、切断部分（切断された箇所を有する部分）１０４ａの形成によって、切断部分１０４ａを有する部分における連続弾性体１０３の交差方向ＣＤの寸法が、切断部分１０４ａを形成する前の連続弾性体１０３の交差方向ＣＤの寸法よりも小さくなるため、切断部分１０４ａを形成していない部分と比べ、伸縮力（弾性力）が低下する。切断部分１０４ａを形成した後、切断部分１０４ａを有する連続弾性体１０３における残余部分１０５の交差方向ＣＤの寸法は、図４中、切断部分１０４ａの右方の寸法がＬ１３であり、切断部分１０４ａの左方の寸法がＬ１４であり、切断部分１０４ａにおける連続弾性体１０３の残余部分１０５の交差方向ＣＤの合計の寸法は、寸法Ｌ１３と寸法Ｌ１４の和であり、切断部分１０４ａの交差方向ＣＤの寸法Ｌ１２だけ、切断部分１０４ａを有していない連続弾性体１０３の交差方向ＣＤの寸法よりも小さくなる。また、連続弾性体１０３の切断部分１０４ａでは、厚さ方向Ｚにおいて、連続弾性体１０３と重なる第１シート１０１の一部も切断され、第１シート１０１に切断部分１０４ｂが形成される。 When the continuous elastic body 103 is cut by the cutter 131, the dimension of the cross direction CD of the continuous elastic body 103 in the portion having the cut portion 104a is a cut portion by the formation of the cut portion (the portion having the cut portion) 104a. Since it becomes smaller than the dimension of the cross direction CD of the continuous elastic body 103 before forming 104 a, the stretching force (elastic force) is reduced as compared with the portion where the cut portion 104 a is not formed. After forming the cut portion 104a, the dimension of the cross direction CD of the remaining portion 105 in the continuous elastic body 103 having the cut portion 104a is such that the right dimension of the cut portion 104a is L13 in FIG. The left dimension is L14, and the total dimension of the cross direction CD of the remaining portion 105 of the continuous elastic body 103 in the cut portion 104a is the sum of the dimension L13 and the dimension L14, and the dimension of the cross direction CD of the cut portion 104a The dimension L12 is smaller than the dimension of the cross direction CD of the continuous elastic body 103 not having the cut portion 104a. In the cut portion 104 a of the continuous elastic body 103, a part of the first sheet 101 overlapping the continuous elastic body 103 is also cut in the thickness direction Z, and the cut portion 104 b is formed in the first sheet 101.
　図６は、切断部１３０を通過させた後の第１シート１０１の平面図である。切断ローラ１３２のカッター１３１は、周方向において等間隔に配置してあるため、連続弾性体１０３の切断部分１０４ａ、第１シート１０１の切断部分１０４ｂとは、機械方向ＭＤに間隔を空けて配置されることとなる。また、連続弾性体１０３の交差方向ＣＤにおける両側縁１０３ａよりも内側において、連続弾性体１０３の一部をカッター１３１によって切断する。このため、連続弾性体１０３を切断する工程において連続弾性体１０３の切れ端が発生することがないため、複合シート１０６に連続弾性体１０３の切れ端が入ることがなく、複合シート１０６の美観を向上することができる。 FIG. 6 is a plan view of the first sheet 101 after passing through the cutting unit 130. Since the cutters 131 of the cutting roller 132 are arranged at equal intervals in the circumferential direction, the cut portion 104 a of the continuous elastic body 103 and the cut portion 104 b of the first sheet 101 are arranged at intervals in the machine direction MD. The Rukoto. Further, a part of the continuous elastic body 103 is cut by the cutter 131 inside the both side edges 103 a in the cross direction CD of the continuous elastic body 103. For this reason, since a cut end of the continuous elastic body 103 is not generated in the step of cutting the continuous elastic body 103, the cut end of the continuous elastic body 103 does not enter the composite sheet 106, and the appearance of the composite sheet 106 is improved. be able to.
＜接合部１４０（ｃ工程）＞
　図１及び図２に示すように、接合部１４０は、ローラ１４１と、押圧部１３６とによって構成してあり、ローラ１４１と、第４ローラ１３４の上部の無端ベルト１３５との間に、連続弾性体１０３を固定した第１シート１０１と、第２シート１０２とを供給し、第１シート１０１の上面に第２シート１０２を押し当て、連続弾性体１０３の周面に塗布した接着剤によって、第１シート１０１及び連続弾性体１０３の上方に、第２シート１０２を固定する。 <Joining portion 140 (step c)>
As shown in FIG. 1 and FIG. 2, the joint portion 140 is constituted by the roller 141 and the pressing portion 136, and the continuous elasticity between the roller 141 and the endless belt 135 above the fourth roller 134 is achieved. The first sheet 101 to which the body 103 is fixed and the second sheet 102 are supplied, the second sheet 102 is pressed against the upper surface of the first sheet 101, and the adhesive applied to the circumferential surface of the continuous elastic body 103 The second sheet 102 is fixed above the first sheet 101 and the continuous elastic body 103.
　図７は、接合部１４０を通過させた後の複合シート１０６の平面図であり、図８は、図７の矢視ＶＩＩＩ－ＶＩＩＩの断面図である。複合シート１０６は、第１シート１０１と第２シート１０２との間に連続弾性体１０３を介在させた状態で、連続弾性体１０３の周面に塗布した接着剤によって、第１シート１０１と第２シート１０２とが互いに接合されている。 FIG. 7 is a plan view of the composite sheet 106 after passing through the joint portion 140, and FIG. 8 is a cross-sectional view of FIG. 7 along arrows VIII-VIII. The composite sheet 106 includes the first sheet 101 and the second sheet 102 with an adhesive applied to the circumferential surface of the continuous elastic body 103 with the continuous elastic body 103 interposed between the first sheet 101 and the second sheet 102. The sheet 102 is bonded to one another.
　カッター１３１によって形成された切断部分１０４ａ，１０４ｂを有する部分では、連続弾性体１０３の伸縮力が弱くなる一方、切断部分１０４ａ，１０４ｂを有していない非切断部分を有する部分では、切断部分１０４ａ，１０４ｂを有する部分よりも伸縮力が強くなるため、１本の連続弾性体１０３が、伸縮力の強い箇所と、伸縮力の弱い箇所とを有することができる。この実施形態の製造装置１００では、連続弾性体１０３が横方向Ｘへ連続して延びるものであるため、連続弾性体１０３を交差方向ＣＤに揺動する必要もなく、第１シート１０１を機械方向ＭＤへ減速する必要もない。このため、第１及び第２シート１０１，１０２並びに連続弾性体１０３を機械方向ＭＤへ高速で搬送することができる。 In the portion having the cut portions 104a and 104b formed by the cutter 131, the stretching force of the continuous elastic body 103 is weakened, while in the portion having the non-cut portion not having the cut portions 104a and 104b, the cut portion 104a, Since the stretching force is stronger than that of the portion having 104 b, one continuous elastic body 103 can have a portion with a strong stretching force and a portion with a weak stretching force. In the manufacturing apparatus 100 of this embodiment, since the continuous elastic body 103 extends continuously in the lateral direction X, there is no need to rock the continuous elastic body 103 in the cross direction CD, and the first sheet 101 can be machined in the machine direction. There is no need to slow down to MD. Therefore, the first and second sheets 101 and 102 and the continuous elastic body 103 can be transported at high speed in the machine direction MD.
＜変形例１＞
　図９は、切断ローラ１３２の変形例を示す、図５と同様の展開図である。この切断ローラ１３２では、各カッター１３１を、機械方向ＭＤ及び交差方向ＣＤに対してそれぞれ傾斜するように配置してある。このため、連続弾性体１０３を切断するときにカッター１３１に加わる力を機械方向ＭＤへ分散することができるとともに、カッター１３１を固定してある切断ローラ１３２のベース部１３２ａに加わる力を分散し、ベース部１３２ａが破損するのを抑えることができる。 <Modification 1>
FIG. 9 is a developed view similar to FIG. 5, showing a modified example of the cutting roller 132. As shown in FIG. In the cutting roller 132, the cutters 131 are disposed to be inclined with respect to the machine direction MD and the cross direction CD, respectively. Therefore, when cutting the continuous elastic body 103, the force applied to the cutter 131 can be dispersed in the machine direction MD, and the force applied to the base portion 132a of the cutting roller 132 to which the cutter 131 is fixed is dispersed. Damage to the base portion 132a can be suppressed.

Since each cutter 131 is disposed to be inclined with respect to the machine direction MD and the cross direction CD, the first sheet 101 formed by the cutter 131 and the cut portions 104 a and 104 b of the continuous elastic body 103 are machine direction It inclines with respect to MD and cross direction CD, respectively. In addition, if the contact area of the continuous elastic body 103 in contact with the cutter 131 is increased, the force applied to the cutter 131 can be dispersed. For example, if the size of the machine direction MD of the cutter 131 is increased and the size of the cross direction CD is increased, the contact area of the continuous elastic body 103 in contact with the cutter 131 can be increased.
