Description

  The present invention relates to a method for forming a garment edge and a structure of the garment edge formed by the method. The garment edge is formed using an adhesive resin tape without sewing, and is not particularly linear. In the edge part of the garment including the curved line, there is no occurrence of shrinkage, deformation, wrinkle, etc., and it is thin and smooth, has a good touch, and realizes an edge part rich in stretchability.

  Conventionally, when folding the edge of clothing in half or attaching tape, etc., it is common to use sewing, but recently, as an edge processing method that does not perform sewing, A method is also provided in which an adhesive sheet or the like is fused to the edge, and the folded portions are fixed to each other, or an edge tape is applied to treat the edge.

For example, in the utility model No. 3052845 (Patent Document 1), as shown in FIG. 12, two end portions 4 of the fabric, such as a neckline, a side wall, and a hemline, which require the tension of the stretchable garment 5, are used. The adhesive sheet 3 having a stretch property, in which the adhesive layer 2 is provided on both sides of the support 1, is sandwiched between the garments 5 folded in half, and the adhesive sheet 3 is bonded to the front and back sides of the fabric by heat press. It is bonded to the fabric and the joint is processed.
Moreover, in JP-A-2005-226175 (Patent Document 2), as shown in FIG. 13, a low melting point resin sheet having appropriate stretchability and a high melting point are provided on one side of the butted portion 8 of the fabric parts 5 and 5, as shown in FIG. The heat sealing tape 9 in which the point resin sheet is laminated and integrated is disposed, and the joining portion is pressed and heated by heating means such as an iron or a hot press, and the heat sealing tape 9 is welded to the fabric parts, and the fabric Parts are joined.

However, in the conventional examples of Patent Documents 1 and 2, it is described that when the adhesive sheet 3 or the heat fusion tape 9 is welded to the cloth 5, it is welded by a heat press (hot press) or an iron. When heating and pressurizing on a flat surface with a press in this way, it is easy for shrinkage, deformation, wrinkles, etc. to occur in the fabric other than the bonded part, and when the clothing edge is a curved line, before pressing In order to align the linear border tape or adhesive resin tape along the curved line of the clothing edge, a process such as sewing or temporary fixing with resin is required, and the border tape is curved even after heating and pressurization. Therefore, there is a problem that the dimensional difference between the outer edge and the inner edge that occurs in the above cannot be absorbed, and wrinkles or sagging occurs in the garment edge and the edging tape.
Furthermore, by pressurizing planarly using a heated heat press or iron, the dough or the edging tape is displaced or deformed, and the resin to which the molten resin is thermally welded adheres to the heated heat press or iron. There are problems such as.
As described above, it is practically very difficult to weld the adhesive sheet along the fabric to the edge of the garment including many curved lines by using a heat press or an iron. At present, the end edge is formed by conventional sewing.

Utility Model No. 3052845 JP 2005-226175 A

  The present invention has been made in view of the above problems, and forms a garment edge by using an adhesive resin tape having an adhesive layer made of a hot melt resin without sewing the garment edge. In some cases, it is an object to solve all the above-mentioned conventional problems.

In order to solve the above-mentioned problems, the present invention provides an edge part obtained by folding an edge part of a garment in two and bonding and fixing inner surfaces together, and an edge part obtained by adhering and fixing an edge tape to the inner or outer edge part of the garment Or a method for forming a garment edge that is bonded and fixed by inserting the edge of the garment into a folded tape.
In a state where an adhesive resin tape provided with an adhesive layer made of a hot melt adhesive is overlapped with the clothing edge or edging tape, the hot melt adhesive is heated by heating means to be in a molten state,
Clothing edge or edging tape in which the molten hot melt adhesive is superimposed and inserted between a pair of non-thermally conductive rollers set slightly wider than the adhesive resin tape and edging tape A method for forming a garment edge, characterized in that the inner surface of the folded part of the garment edge or between the garment edge and the edging tape are bonded and fixed via the hot melt adhesive. Is provided.

As the heating means, heating means by a heater or hot air is provided from one side or both sides immediately before insertion between the rollers, and the adhesive resin tape, edge tape or / and clothing edge is heated by the heating means. preferable.
Specifically, there is provided a welding apparatus provided with the pair of non-thermal conductive adhesive feeding rollers arranged opposite to each other and a hot air blowing pipe arranged along the outer surface of the roller on the feeding side to these rollers. ,
Immediately before feeding the adhesive resin tape along the garment edge and the edging tape attached to the garment edge between the pair of rollers to be driven to rotate, heat with hot air blown from the outlet of the hot air blowing pipe, The hot-melt adhesive layer is melted, and the molten hot-melt adhesive is infiltrated and fixed to the garment and / or the edging tape by pressing between the adhesive feeding rollers.
In addition, after heating the two adhesive resin tapes with heating means using a heater box to a molten state, they are overlapped with a gap in the center along the length direction of the border tape, and inserted and pressed between the rollers. Then, two adhesive resin tapes are bonded and fixed to the border tape, folded in half so that the adhesive resin tape side of the border tape is the inner surface side, and the clothing edge is inserted into the inside and heated by heating means that blows hot air Further, the hot melt adhesive that has permeated the border tape is melted, and the border tape is adhered and fixed to both sides of the garment edge by pressurization between the rollers.

Thus, the welding of the present invention is set to be slightly wider than the adhesive resin tape and the edging tape by heating immediately before pressing, rather than the heat press and iron that pressurize a flat and wide area conventionally used. A method of applying pressure by line contact using a rotating roller made of a non-thermally conductive material is employed.
Since pressure is applied by a roller instead of pressing by a press as described above, it is possible to apply pressure while simultaneously pulling the adhesive resin tape and the garment edge or / and the edging tape. Therefore, even if these are stretchable materials and the garment edge includes curved lines, the adhesive resin tape and the garment edge or / and the edging are not generated without wrinkles. The tape can be heat welded. And, since these rollers can also adjust the rotation rate, it is also possible to change the rotation rate of the upper and lower rollers and to make the operation feed, and further, depending on the thickness of the clothing edge, adhesive resin tape, edging tape, Since the reduction force can also be adjusted, a smooth clothing edge without wrinkles can be formed by making an appropriate adjustment according to use.
The pair of upper and lower rollers is preferably an elastic roller made of rubber or elastomer having a required hardness. By using an elastic roller, even if a step is generated on the surface to be pressed, pressure is applied while absorbing the step. Can be evenly loaded.

  In the present invention, as described above, the heating to the hot melt adhesive is mainly performed by a heating means provided separately from the adhesion feeding roller, and the heating is shared with the pressurization, and the non-thermally conductive material is used. Since the rotating roller formed is used in a non-contact manner with the adhesive resin tape, it is possible to prevent the molten hot melt adhesive from adhering to the heating means and the pressure means.

  The hot air blowing pipes, which are one of the heating means, are paired along the outer surface on the feeding side of the pair of rollers, and the hot air blowing pipe tips are arranged facing each other toward the contact point side of the rollers, It is preferable that hot air is blown from both sides toward the adhesive resin tape stacked on the part or / and the edging tape. Thus, by blowing hot air from the upper and lower sides, the hot melt resin of the adhesive resin tape can be efficiently and reliably welded. The temperature of the hot air is preferably adjusted in the range of 130 ° C to 190 ° C.

Specifically, the welding device is arranged only by a combination of a hot air blowing pipe and a pair of upper and lower adhesive feed rollers, performs a required welding in the welding device, and after passing through a required process, conveys it again to the welding device, It may be used repeatedly.
Also, a heater box and a pair of upper and lower adhesive feed rollers are combined as a first welding device arranged on the upstream side, and a combination of a hot air blowing pipe and a pair of upper and lower adhesive feed rollers is used together as a second welding device arranged on the downstream side. Also good.

Examples of the structure of the garment edge portion of the present invention include the following three types.
(1) An edge part of a so-called bi-fold structure in which the edge part of the garment is folded in two and the inner surfaces thereof are bonded and fixed.
(2) An edge portion of a so-called sticking structure, in which a border tape is bonded and fixed to an edge portion on the inner surface side or outer surface side of clothing.
(3) An edge portion of a so-called piping structure in which an edge portion of a garment is inserted and fixed to a half-folded edging tape.
In the present invention, an optimum method is provided as a method of forming the edge portions of (1) to (3).

  In the piping structure of (3) using the border tape and the affixing structure of (2), the single-layer adhesive resin tape consisting only of a hot melt adhesive is used, and the border tape is not used. In this case, it is preferable to use the adhesive resin tape having a three-layer structure in which adhesive layers made of a hot melt adhesive are provided on both surfaces of the base tape.

  (1) The method for forming a foldable garment edge without using the edging tape comprises the three-layered adhesive resin tape provided with adhesive layers made of the hot melt adhesive on both sides of the base tape. In the state where one surface of the adhesive resin tape is superposed on the edge of the clothing, the hot melt adhesive on the one surface side is heated to the molten state by the heating means, and then inserted between the rollers to be inserted on the one surface side. A hot melt adhesive is infiltrated into one surface of the garment edge to bond and fix the adhesive resin tape, and after the hot melt adhesive on the other side is melted by the heating means, the adhesive resin tape is The garment edge is folded back in a sandwiched state, inserted and pressed between the rollers, and the hot melt adhesive on the other side is infiltrated into the folded inner surface to be bonded and fixed.

The garment edge part formed by the above-mentioned method is applied to the garment edge part by bonding and fixing the inner surfaces of the folded parts of the garment edge part with the base tape interposed therebetween. Compared to the conventional method in which only the garment edge is folded and sewn, it is also possible to insert the elastic tape into the bag-like portion of the folded edge and to stretch the folded tape There is no need to sew, the number of parts is reduced and the processing cost can be kept low.
Hot melt adhesive penetrates into the fabric with a slight refracted crease at the edge of the garment and the folded back edge, and only the base tape of the adhesive resin tape is inside the fold. Since it is interposed, the thickness of the end edge portion can be reduced, the fold mountain line portion and the folded back end edge portion can have a good touch, and the structure does not resonate with the outer.

The following two methods can be adopted as a method for forming the garment edge portion of the affixing structure (2).
The first method uses a single-layer adhesive resin tape made only of a slightly narrow hot melt adhesive with both ends slightly smaller than the width of the border tape, and the hot melt adhesive is overlapped on the border tape. , After being heated to a molten state by the heating means, inserted and pressed between the rollers, and a hot melt adhesive penetrated into the edging tape,
Thereafter, the hot melt adhesive is heated to the molten state by being heated by the heating means in a state where the side on which the hot melt adhesive has penetrated the edging tape is superimposed on the inner edge or outer edge of the garment. After that, it is inserted and pressed between the rollers, the hot melt adhesive is permeated into the garment edge, and the edge tape is bonded and fixed to the inner surface or the outer surface of the garment edge.
The second method uses the single-layer adhesive resin tape made only of a slightly narrow hot melt adhesive with both ends slightly smaller than the width of the border tape, and the hot melt adhesive is overlapped on the border tape. Further, the hot melt adhesive is overlapped with the edge of the garment tape and the garment edge, and the hot melt adhesive is heated to a molten state by the heating means, and then inserted and applied between the rollers. The hot melt adhesive is simultaneously permeated into the edge tape and the garment edge, and the edge tape is adhered and fixed to the inner surface or the outer surface of the garment edge.

  The garment edge portion of the edging tape affixing structure formed by the above method is obtained by using the single layer adhesive resin tape comprising only the hot melt adhesive for the edging tape and the garment edge portion. After being heated to a molten state by the heating means, inserted and pressed between the rollers, penetrated into the edge tape and the clothing edge, and the edge tape was adhered and fixed to the inner surface or the outer surface of the clothing edge. Compared to the conventional method of sewing edging tape on the edge of clothing, there is no occurrence of claws due to the thickness and hardness of the sewing thread or tension of the sewing thread, resulting in a thin and soft finish, and the touch of the edge It can be made a structure that is good and does not resonate with the outer.

(3) The piping structure forming method of the piping structure according to (3) uses two single-layer adhesive resin tapes made of only the hot-melt adhesive, and uses the two adhesive resin tapes as a first heating means. Between the rollers provided immediately after the first heating means, after being heated and melted in a heater box, and overlapping with a gap at the center and both ends along the length direction of the border tape. Inserted and pressed into the two tapes of the adhesive resin tape consisting only of the hot melt adhesive into the edging tape,
Fold the edging tape in two so that the side to which the adhesive resin tape is bonded and fixed is the inner surface side, insert the garment edge into the fold tape, and the folded fold line part and the folded both ends After the hot melt adhesive that has been permeated in a state with a slight refusal is heated and melted by hot air as the second heating means, it is inserted and pressed between the rollers provided immediately after the second heating means, The edging tape is adhesively fixed to both sides of the clothing edge.

In the method for forming the clothing edge portion of the piping structure, the adhesive resin tape is not attached to the center in the width direction of the border tape, and the two adhesive resin tapes are applied to the heating and pressurizing means along both sides in the width direction. Attach to the edge tape, fold the edge tape so that the adhesive-fixed adhesive resin tape is on the inner surface side, insert the clothing edge inside, and apply the heating and pressure means to the clothing edge. Since the adhesive resin is not fused and penetrated in the middle in the width direction of the half-folded edging tape, the fold line part of the double-folded adhesive resin tape has a hollow portion. In addition, both ends of the folded adhesive resin tape are soft and feel good.
In this method, the two adhesive resin tapes are first melted in the heater box of the first heating means, inserted between the first rollers, and bonded and fixed to the edging tape. You may use the hot air spraying means which is a 2nd heating means as a heating means.
It is preferable that the heating temperature of the heater box which is the first heating means is 90 ° C. to 140 ° C., and the hot air temperature which is the second heating means is 130 ° C. to 190 ° C.

In order to prevent the hot melt adhesive melted by heating from coming into direct contact with the roller, a release paper is adhered to the surface of the adhesive resin tape, which is in contact with the roller. Accordingly, when the adhesive resin tape and the garment edge or the adhesive resin tape and the edging tape are overlapped and passed through the roller, one surface side in contact with the roller is the garment edge or rim tape side, and the other surface side in contact with the roller is The release paper is on the side.
In the case of (1) above, a means for removing the release paper is provided after pressurizing with the roller in a state where the adhesive resin tape is overlapped on the edge of the garment. In the case of (2) 1 and (3) Means is provided for removing the release paper after pressing by the roller in a state where the adhesive resin tape is overlapped with the border tape. Further, in the case of (2) above, means for removing the release paper immediately before the heating means arranged on the feeding side of the roller in a state where the edge tape, the adhesive resin tape and the clothing edge are overlapped. Is provided.

As the hot melt adhesive used in the present invention, polyamide, polyester, polyurethane, polyolefin and the like are used.
In the case of a three-layer structure in which an adhesive layer made of a hot melt adhesive is provided on both sides of the base tape, the thickness of each adhesive layer is 20 to 80 μm, the thickness of the base tape is 50 to 150 μm, and the total thickness Is about 150 to 250 μm. An elastic tape made of polyurethane is preferably used as the base tape.
In the case of a single-layer tape consisting only of a hot melt adhesive, about 50 to 100 μm is preferable.

Using the adhesive resin tape having a three-layer structure, the stretchable base tape is interposed between the folded portions of the garment edge at the garment edge having the bi-fold structure of (1). However, it also serves as a rubber tape that is trimmed to the edge of the garment, and can improve the adhesion to the skin when the garment is underwear.
In addition, when the lace having a stretch property is used as the edging tape of the clothing edge portion of the affixing structure of (2), the clothing edge portion can be stretched in the same manner, and the adhesion of the clothing edge portion to the skin is added. can do.

In any of the cases (1) to (3), the shape of the clothing edge often includes a curved line. In this case, if the rimming tape and the adhesive resin tape are passed through the rollers by being bent or stretched while being curved along the clothing edge, without causing wrinkles at the curved clothing edge, It is possible to process the edge portions that are smoothly continuous.
In addition, when the clothing edge is a curved line, when trying to heat / compress on a flat surface by the hot press presented in Patent Documents 1 and 2, before the heating / compression, a linear border tape or adhesive In order to keep the resin tape along the curved line of the clothing edge, a process such as sewing and temporary fixing with resin is required, and the outer edge and the inner edge are generated by curving the edge tape after heating and compression. The dimensional difference between the edges cannot be absorbed, and wrinkles or slack are generated on the garment edge and the edging tape.

In addition, when clothing is underwear, it is often formed from a stretchable material, so the base tape of the adhesive resin tape is made of a stretchable material, and the stretchable material is also used for the edging tape. In addition, all the members forming the garment edge are made of a stretchable material.
In the present invention, heating is performed by the heating means by adjusting the rolling force of the upper and lower rollers and / or differential adjustment of the upper and lower rollers and / or the edging tape according to the thickness, tightness, curvature, etc. of the material used in the garment. In addition, since it is fixed through the hot melt adhesive melted by the pressurizing means, it does not generate wrinkles on the garment edge and forms the garment edge that gives the necessary tightening force. And the clothing edge can be expanded and contracted in the same manner as the clothing body.

  As described above, in the present invention, since no sewing is performed by using an adhesive resin tape made of a hot melt adhesive, processing is simplified, and no thread is used, so that the surface is smooth and the touch is improved. it can.

The adhesive fixing with the hot melt adhesive is performed by first melting the hot melt adhesive by blowing hot air or the like and then inserting and pressing between the non-thermally conductive upper and lower rollers, and the molten hot melt adhesive is applied to the clothing end. It permeates the edge and edging tape, and heating and pressurization are performed separately.
In this way, since the roller is used for pressurization in the present invention, it is possible to prevent the inevitable generation of wrinkles when heating and pressurizing planarly by a hot press provided in the conventional example, and to expand and contract Even in the case of sexual materials, the bending portion can be adjusted by adjusting the rolling force of the upper and lower rollers and / or differential adjustment of the upper and lower rollers and / or the edging tape according to the thickness, stretchability or bending of the material used in the clothing. By applying pressure while absorbing the circumferential length difference between the inner circumference and the outer circumference to form the clothing edge, it is possible to prevent wrinkles and form a smoothly continuous edge.

  In addition, when a pair of upper and lower hot air blowing pipes are arranged along the outer peripheral surface on the roller insertion side as heating means, and heated in a non-contact manner with hot air, the molten hot melt resin is not brought into contact with the heating means, and The superposed portion can be heated from both sides by hot air from both sides, and the bonding and fixing can be performed efficiently.

Furthermore, there are the following advantages compared with the case where the end edge is formed by sewing.
(A) There is no suppression of the elongation due to the yarn, and an elongation equivalent to the fabric of the clothing edge can be imparted to the edge.
(B) In the case of sewing, if the tape to be sewn is thin, it is not possible to perform sewing with a smooth surface, but there is no limit on the thickness when bonding with a hot melt adhesive, and the edge portion The thickness of the adhesive resin tape and the edging tape used for the garment, as well as the thickness of the fabric body at the garment edge, can be made very thin. As a result, the edge can also be made thin. Can prevent the edge part from echoing the outer.
(C) In the case of sewing, the sewing thread is exposed on the surface, and in the case of underwear, it contacts the skin. On the other hand, since the sewing thread is not used in the present invention, the touch is good.
(D) A curve that is smoothly curved as compared with the case of sewing can be obtained.
(E) In the conventional method in which the garment edge is folded back and sewn, if the garment edge is intended to improve the adhesion to the skin, the bag-like part of the fold edge will be stretchable. It is necessary to add a method of inserting a tape or the like, or a method of sewing and attaching a stretchable tape at the same time when sewing a folded portion, but in the present invention, it has stretchability. By using an adhesive resin tape having a three-layer structure in which an adhesive layer made of a hot melt adhesive is provided on both surfaces of a base tape made of polyurethane, necessary adhesion can be obtained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment of the present invention. The first embodiment has a structure in which an edging tape 20 is attached to the outer surface of the edge 5 a of the garment 5 via a single-layer adhesive resin tape 21.

  The garment edge portion forming method of the first embodiment uses one welding device 11 provided in the garment edge portion forming apparatus schematically shown in FIG. The pressure is performed by one welding apparatus.

The welding apparatus 11 includes a pair of upper and lower rollers 30 and 31 configured as shown in FIG. 2 and a pair of upper and lower hot air blowing pipes 32 and 33 disposed immediately before the rollers 30 and 31 are inserted.
The rollers 30 and 31 are made of a non-thermally conductive rubber or elastomer, and are formed of an elastic roller having a required hardness. These rollers 30 and 31 are rotationally driven rollers. On the insertion side between these rollers, the pair of upper and lower hot air blowing pipes 32 and 33 are provided along the outer peripheral surface of the rollers 30 and 31 at the intermediate portion in the roller axial direction. It is arranged. The hot air outlets 32 a and 33 a at the tips of the hot air outlet pipes 32 and 33 are arranged to face each other in the contact direction of the rollers 30 and 31. The temperature of the hot air blown out from the hot air blowing pipe is adjusted in the range of 130 ° C to 190 ° C.

  In the apparatus, the welding apparatus 11 is arranged along the conveyance path, and a winding coil 40 of the rim tape 20 and a winding coil 41 of the single-layer adhesive resin tape 21 are installed on the upstream side. A pressing guide material 12 for superimposing the adhesive resin tape 21 and the edging tape 20 respectively supplied from the winding coils 40 and 41 is provided, and the welding device 11 is installed downstream of the pressing guide material 12. A release paper removing means 25 is disposed at a position where the welding apparatus 11 is exited.

As shown in FIG. 3, the edging tape 20 attached along the edge 5a that ends the garment 5 is a thin stretch tape having elasticity.
The single-layer adhesive resin tape 21 formed only from the hot melt adhesive has a thickness of 10 to 100 μm, and in this embodiment, is 50 μm. A release paper 22 is adhered to one surface of the adhesive resin tape 21.

  The step of affixing the rim tape 20 to the garment edge 5a uses the single layer adhesive resin tape 21 made of the hot melt adhesive, and the garment edge 5 and the rim tape 20 together with the adhesive resin tape 21. The hot melt adhesive is heated to a molten state by the heating means 32, 33 that blows the hot air, and is then pressed between the rollers 30, 31 to apply the hot melt adhesive to the rim tape 20 and The garment edge 5 is infiltrated, and the edging tape 20 is adhered and fixed to the inner surface or the outer surface of the garment edge 5.

Since the molten hot melt adhesive is not brought into contact with the rollers 30 and 31, and the rollers 30 and 31 are made of a non-thermal conductive material and are not heated, the molten hot melt is melted on the surfaces of the rollers 30 and 31. Adhesive does not adhere.
In the operation of adhering and fixing the laminated body of the edging tape 20 and the garment edge 5 a with the welding device 11, while applying the required tensile force to the edging tape 20, the garment edge 5 a is aligned with the edging tape 20. Since the passage between the rollers 30 and 31 is prevented, generation of wrinkles can be prevented, and the hot melt welding agent deposited on the surfaces of the rollers 30 and 31 does not adhere.

By the above-mentioned method, the garment edge part which affixed the edging tape 20 on the outer surface of the edge part 5a of the garment 5 is formed without sewing.
Since the hot melt adhesive permeates into the cloth at the garment edge, the garment edge and the edging tape can be firmly bonded and fixed, and the edge is processed by sewing. In comparison, the thickness of the yarn is eliminated, and the edge portion of the garment on which the edge tape with a thinned step is made as thin as possible can be realized, so that it does not resonate with the outer.
Further, even in the case of clothing having elasticity, the adjustment of the rolling force of the upper and lower rollers, the upper and lower rollers and / or the edging tape according to the thickness, tightness or curvature of the material used in the clothing. Since the clothing edge is formed by heating and pressurizing by differential adjustment, the clothing edge 5a and the edging tape 20 can be bonded and fixed without generating wrinkles, and the clothing edge is the same as the clothing body. Can be expanded and contracted.
In particular, in the welding apparatus 11, the adhesive resin tape is previously melted by the hot air blowing pipes 32 and 33 and penetrates into the edge tape and the clothing edge, and then inserted and pressed between the rotating rollers to be bonded and fixed. Compared with the case where heating and pressurization are performed simultaneously using a hot press, the surface of the garment edge 5a can be made smooth without causing wrinkles, and the appearance is improved. .
In addition, the roller made of a non-thermally conductive material is obtained by heating a hot melt adhesive in a non-contact manner with hot air immediately before inserting the border tape and / or the clothing edge and the adhesive resin tape into the roller. Since the heating and pressurization are separated by only applying the pressure at, the melted hot melt adhesive surely penetrates into the clothing edge and the fabric of the edging tape, thereby increasing the peel strength. be able to.

  FIG. 4 shows a brassiere 100 in which the rimming tape 20 having the above structure is attached to the edge of the garment. In the brassiere 100, an end edge portion 200A to which the rimming tape 20 is pasted is formed along a curved end edge formed from the upper end edge of the cup portion 101 and the upper end edge extending from the side side continuous to the upper end edge to the back cloth 102. Provided. Moreover, the edge part 200B which affixed the edging tape 20 from the lower end edge of the front body part of the lower end of the cup part of the brassiere 100 to the lower end edge of the back cloth 102 is provided.

In the edge portion 200A where the edge tape 20 of the upper edge is pasted, the upper edge of the cup portion is greatly curved.
In this curved portion, when the edge tape 20 and the edge of the cup portion are passed between the rollers 30 and 31 of the welding apparatus 11, the clothing edge 5a and the edge tape 20 are formed so as to form an arc shape. I'm pulling.
In this way, wrinkles are generated on the edging tape 20 along the garment edge portion 5a curved in an arc shape by being inserted and pressed between the rollers 30 and 31 while being pulled in an arc shape and fixed by adhesion. Can be installed without.

5 to 7 show a second embodiment.
In the second embodiment, the edge portion 5a of the garment 5 is not used as an edge tape, but only the adhesive resin tape 21 ′ having a three-layer structure shown in FIG. The inner surface of each of the parts 5a-1 and 5a-2 has a structure in which the hot melt adhesives of the adhesive layers 21b ′ and 21c ′ on both sides of the adhesive resin tape 21 ′ are infiltrated and bonded and fixed.

  The adhesive resin tape 21 'has a three-layer structure in which resin layers 21b' and 21c 'made of a hot melt adhesive are provided on both surfaces of a base tape 21a' made of stretchable urethane. The base tape 21a 'has a thickness of 50 to 150 [mu] m, and the resin layers 21b' and 21c 'on both sides have a thickness of 25 to 50 [mu] m, respectively. A release paper 22 is adhered to the adhesive layer 21c 'side. The width of the adhesive resin tape 21 ′ is narrower than the width of the border tape 20 so that the molten hot melt adhesive does not protrude from the border tape 20.

In the method of forming the edge portion of the second embodiment, as in the first embodiment, one welding device 11 is used, and heating and pressurization twice are performed by one welding device.
As shown in FIG. 6, first, an adhesive resin tape 21 ′ having a three-layer structure is superposed on the clothing edge 5 a, and the hot melt adhesive for the adhesive layer 21 b ′ of the adhesive resin tape 21 ′ is welded by the welding device 11. Is penetrated into the garment edge 5a and the adhesive resin tape 21 'is fused and fixed, and the release paper 22 on the other side is removed.
