Embodiment Construction

[0018] Hereinafter, the present invention will be described in detail based on drawings showing best embodiments. figure 2 A plan view showing the first embodiment of the stitch structure of the present invention, the stitch portion on the back side of the sewn material is enlarged and shown.

[0019] The stitch structure shown in this figure is formed by three needle threads 2, 2, 2, and on the three thread ring rows 20, 20, 20 arranged in parallel to each other on the back side 11 of the sewn cloth 1, two sets of threads are entangled (No. One set of lines and the second set of lines) are formed.

[0020] The three needle threads 2, 2, 2 pass through the sewing fabric 1 intermittently conveyed along the direction indicated by the white arrow symbol in the figure by keeping their respective needles moving up and down, and the above-mentioned thread loop row 20 , 20, 20 are formed by the arrangement of the coiled wire loops left at the penetration positions of each needle th...

Abstract

In the stitch structure of the present invention, several rows of loops are arranged on the back of the fabric to be sewn, the first double-thread overlock portion formed by winding the first set of threads around all the rows of loops, and The second double-thread lock seam part formed by the second set of threads being entangled with a part of the above-mentioned several loop rows is combined, so in addition to improving the sewing strength, it can moderately suppress the stretchability and prevent cutting Unnecessary disassembly caused by wires.

Description

technical field [0001] The present invention relates to a stitch structure (stitch type) for forming a sewn product by using a sewing machine. Background technique [0002] In sewing using a sewing machine, especially an industrial sewing machine, various stitch structures have been put into practical use in order to suit the type and location of the sewing product. These stitch structures, as described in "Sewing Book" (published by the Japan Textile Association Publishing Bureau), are regulated and published by the Standards Division of U.S. government in the Japanese Industrial Standard (JIS-B9070) Expressed as a reference. [0003] As one of such stitch structures, there are double lock stitches, and as a stitch structure obtained by adding fancy threads to the double lock stitches, there are flat seams. stitches). In addition, double lockstitch is a stitch structure that is indicated by a symbol of 400 yarn counts in the US standard, and a symbol of D in JIS. In add...
