[0004]
In the process of sewing a cover fabric used to cover a three-dimensional article such as a chair or sofa, the fabric is partially squeezed according to the three-dimensional shape of the chair or sofa, and a depression or a ridge is formed at the squeezed portion. The squeezing sewing is performed in which the wavy ridge generated at the squeezed portion is fixedly set by the perforated thread. For this purpose, the sew-only sewing machine used is well known, and an automatic fabric feeding device for overfeeding the fabric is provided. The sewing machine exclusively used for sew sewing sews the perforated thread on the fabric while overfeeding. The corrugated wrinkle is generated on the fabric according to the overfeed rate, and the corrugated wrinkle is fixedly set by the perforated line. ing.
[0005]
[Problems to be solved by the invention]
The automatic sewing machine for overfeeding the fabric is attached to the sewing machine exclusively used for squeezing, but it is necessary to finely fold a hard fabric with a bending resistance of 30 mm or more and a thick fabric with a thickness of 0.4 mm or more. It is difficult to feed to the automatic fabric feeding device, the overfeed rate to be fed is likely to vary, and corrugated wrinkles with uniform waveform pitch are unlikely to occur. In addition, the knitted fabric rich in stretchability tends to vary in the overfeed rate. Even in a woven fabric, it is difficult to generate a corrugated wrinkle with a corrugated pitch in a hard and thick elastic fabric in which a thick monofilament elastic yarn having a fineness of 500 to 4000 dtex is woven, and even in a flexible and flexible fabric, Because it is stretchable in the direction crossing the warp and weft, the corner of the rectangular sheet fabric cut into a rectangle according to the seat stool and backrest is squeezed along the sewing line set in an arc shape, It is difficult to sew perforated stitches to a hemispherical shape.
[0006]
OBJECT OF THE INVENTION
Accordingly, the present invention generates a beautiful corrugated wrinkle with a uniform wavy pitch at the required constricted portion of the fabric regardless of the stretchability, hardness, or thickness of the fabric, and is fixedly set by the perforated line. Sewing the fabric beautifully in three dimensions, especially the corners of rectangular sheet fabrics cut into rectangles according to the seat stool and backrest along the sewing line set in an arc shape, The purpose is to sew the stitches and sew them neatly into a hemispherical shape.
[0007]

[0009]
DETAILED DESCRIPTION OF THE INVENTION
The shrinkable tape 14 includes water-shrinkable tape made of vinylon and other water-shrinkable fibers and water-shrinkable films, heat-shrinkable tape made of Tevilon and other heat-shrinkable fibers and heat-shrinkable films, spandex and other elastic materials. An elastic tape made of an elastic resin such as fiber, rubber, or the like, or a narrowed tape in which one end of the narrowed yarn 18 is locked in the lengthwise direction and the other end protrudes long so that the yarn can be removed is used.
[0010]
The water-shrinkable tape 14 is sewed to the fabric 13 along the sewing line 17 and then humidified and shrunk. The heat-shrinkable tape 14 is sewed to the fabric 13 along the sewing line 17 and then heated to shrink. The elastic tape 14 is pulled to a required length and stitched to the fabric 13 in the stretched state. In the squeezing tape 14, it is sewn to the fabric 13, and then the squeezing thread 18 is pulled to generate the corrugated wrinkles 16 (FIG. 3). When using a woven fabric for the tape 14, a part of the warp or weft continuous in the length direction is used as the narrowed yarn 18, and a knot is attached to one end thereof so that the tape 14 is not pulled out. It is also possible to pick the end (18) from the tape 14 and pull it (the other end 18) to generate the corrugated scissors 16.
[0011]
In particular, the corner of the rectangular sheet fabric 13 cut into a rectangle in accordance with the seat stool and the backrest (FIG. 1), squeezed along the sewing line 17 set in an arc shape, and the sewing thread 11 is sewn. When the sewing line 17 is set in an arc shape, as in the case where it is raised and sewed into a quadrilateral shape (FIG. 2), the tape applied to the fabric 13 along the arc-shaped sewing line 17 It is advisable to temporarily bond the cloth 14 to the fabric 13 with an adhesive or a pressure-sensitive adhesive before sewing so that the position of 14 does not shift during sewing. For this purpose, an adhesive or a pressure-sensitive adhesive is preferably applied and laminated on the back surface of the tape 14. A heat-fusible resin is preferably used for the adhesive or pressure-sensitive adhesive.
[0012]
The corrugated wrinkles 16 generated by the shrinkage of the tape 14 can be heat-set by dry heat treatment if the fabric 13 is made of a heat-settable thermoplastic fiber. In the case of a thermoplastic fiber, it can be set by applying a resin solution. The fabric 13 to which the corrugated ridges 16 are attached is stitched with other members to finish a required sewing product. The other members to be sewn are woven fabrics, knitted fabrics, non-woven fabrics, etc. like natural leather and synthetic leather. It may be other than the cloth, or may be another part of the cloth 13 to which the corrugated ridge 16 is attached. The corrugated ridge 16 is held and fixed to the fabric 13 by the perforated line 11, but the perforated line 11 may be a perforated line for sewing with other members. The tape 14 applied to generate the corrugated fold 16 can be cut and removed from the fabric 13 after the corrugated ridge 16 is fixedly set by the perforated line 11. That is, the tape 14 is means for three-dimensionally squeezing the fabric 13 and does not need to be left attached to the finished sewing product.
[0013]
【The invention's effect】
According to the present invention, the corrugated ridge 16 for squeezing the fabric 13 three-dimensionally is generated by contracting the tape 14 attached before sewing, not by the automatic fabric feeding device of the sewing machine dedicated to sewing. Regardless of the stretchability, hardness, and thickness of the fabric, even a stiff fabric with a uniform wavy pitch, a hard fabric with a bending resistance of 30 mm or more, or a thick fabric with a thickness of 1 mm or more, and a fineness of 500 to 4000 dtex. Even at the corner where the continuous direction W of the warp and the continuous direction C of the weft of the rectangular sheet geoelastic fabric 13 which is stretched with a thick monofilament elastic yarn is crossed, the sewing line 17 is set in an arc shape. It is easy to squeeze and squeeze up the wave pitch along the four hemispheres and sew it together, and efficiently obtain a three-dimensional sewing product that matches the three-dimensional shape of a chair, sofa, etc. Door can be.
