Abstract

This invention relates to a sewing machine with skipped stitch mechanism of flat joint stitch. The said sewing machine comprises a needle bar mechanism (2), a needle cylinder mechanism (5) and a skipped stitch mechanism of flat joint stitch (6). The needle bar mechanism (2) seesaw needle bar (7), flat joint (10) held at the lower end of the needle bar. The needle cylinder mechanism (5) is composed of outer needle cylinder (49) and inner needle cylinder (48), and the flat joint stitch is formed along with seesaw movement of flat joint (10). The skipped stitch mechanism of flat joint stitch (6) makes the needle cylinder mechanism (5) move from the position of flat joint (10) to the position of moving away from the flat joint, and the stitches are skipped at the position of moving away from the flat joint.

Description

technical field [0001] The invention relates to an industrial sewing machine capable of consciously skipping stitches of lockstitch stitches. Background technique [0002] For example, for efficient production, sewing of denim pants, slacks, etc. is performed through the following steps. That is, as shown in FIG. 25 , in the opening of the elongated belt fabric piece 200 bent in a substantially U-shape in cross section, the ends of the front and rear body large pieces of fabric 201 are inserted, and each of the front and back body large pieces of fabric is placed into the opening. 201 ... and the inner side 202 of the belt fabric piece 200 and the outer side 203 of the belt fabric piece 200 where there are no front and rear body large fabric pieces 201 ... are lock stitched only at a given distance A, and thereafter only a given distance B is produced. The jump stitch portions (non-stitched portions) 204 and 205 where lock stitching is not performed are further locked stitc...
