Problems solved by technology

However, in this patent document 2, it is not described to the extent of solving the unique technical problems that arise when butt-sewing fabrics having different thicknesses.
The inventors of the present invention have found a technical problem that when the end edge of the fastener tape and the end edge of the main fabric are butted and sewn using this technique, the fastener tape is sewn to undulate in the longitudinal direction.
Moreover, it is technical common sense that conventional slide fasteners are sewn by overlapping as described above, and sewing by other sewing methods is neither suggested in this Patent Document 2, nor is there any prior art document disclosing such an idea.

Embodiment Construction

[0059] Refer to the attached Figure 1 One embodiment of the present invention will be described. figure 1 It is a plan view showing one surface of a sewn product 10 according to one embodiment, figure 2 It is a top view showing the other surface of the sewn product 10 . As shown in these figures, the sewn product 10 is made by using the end edge (hereinafter also referred to as "tape edge") 12A of the fastener tape 12 as an example of the first cloth, and the material thicker than the fastener tape 12 as the second cloth. It is a sewn product in which the edge (hereinafter also referred to as "cloth edge") 14A of the main fabric 14 of the fabric is sewn in a butt-butted state without overlapping. The zipper tape 12 is made of fabric or knitted fabric. The main fabric 14 is a fabric forming clothes, bags, etc., and is, for example, felt fabric, knit fabric, wool knit compressed fabric, jersey fabric, etc., but is not limited thereto. The sewn product 10 is clothes, bags,...

Abstract

Provided is a sewn product in which a tape edge of a fastener tape and a material edge of a main material that is thicker than the fastener tape are stitched together in an abutted state, wherein the tape edge and the material edge are stitched together with one bobbin thread and two needle threads, the two needle threads being interlocked with the one bobbin thread to form a plurality of rows of zigzag stitched seams. In addition, the fastener tape and the main material are respectively fed with feed dogs that are set at different feed rates, while the first and second materials are pressed at an equal pressure.

Description

technical field [0001] The present invention relates to a sewn product and a method of sewing cloth, in particular to a sewn product made by sewing the ends of cloth with different thicknesses together, for example, the end edges of a zipper tape and the end edges of a main cloth, and the seam thereof system method. Background technique [0002] When sewing the fastener tape for the zipper and the main fabric, in order to ensure the strength of the seamed part, after the main fabric is overlapped with the one side of the fastener tape in the width direction, the main fabric is stitched flat. The fabric is folded back and further stitched. In addition, the hem is usually also overlapped with the other side of the zipper tape, sewn flat with the main fabric, and after the hem is folded back, it is further sewn together with the main fabric. As a result, the suture becomes thicker and stiffer. In addition, since the fastener tape and the main cloth are partially overlapped a...
