Abstract

This invention relates to a sewing machine. In order to be corresponding with tailoring of the product of different tact system on the unner side and the outer side of the cestus blank patch, the sewing machine has skipped stitch mechanism of whipstitch and skipped stitch mechanism of flat joint stitch and with crimping and flat seaming function. The curved needle mechanism is composed of a curved needle and a dividing sinker device and a whipstitch formed along with seesaw movement of whipstitch of needle bar device. The whipstitch of skipped stitch mechanism is set to make the dividing sinker device move between the guiding yarn position and retreating position, and the stitch is skipped at the retreating position. The skipped stitch mechanism of whipstitch can make the needle cylinder mechanism move from position close to the flat joint needle to position apart from the flat joint needle, and the stitch is skipped at the position apart from the flat joint needle.

Description

technical field [0001] The invention relates to an industrial sewing machine capable of locking and flat sewing and realizing conscious skip stitches of lock stitches and conscious skip stitches of flat 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. 28 , 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 the front and rear body large pieces of fabric are placed. 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 stit...
