shuttle embroidery machine

Abstract

A shuttle embroidery machine, wherein a drive beam of the shuttle embroidery machine moves up and down on a movement path inclined to the vertical through a crank linkage (5, 7, 25, 31 and 33). The linear motion path is preferably achieved by a linkage that snaps onto the drive beam without the need for linear guide members.

Description

technical field [0001] The invention relates to a shuttle embroidery machine. Background technique [0002] Shuttle embroidery machines have been known for more than a century and work according to a two-thread system, ie one needle thread and one shuttle thread, wherein for each stitch the needle thread is wound by the shuttle thread. The front needle provided with the small hole conveys the needle thread through the sewing material to the back side of the sewing material, and the needle thread forms a loop during the withdrawal of the sewing needle. Subsequently, a shuttle containing the shuttle thread is passed through the loop. Shuttle embroidery machines include a large number of stitches arranged in a row and a corresponding number of needles and shuttles. There is a drive beam that moves the shuttle up and down in a slightly vertically inclined position.

AI Technical Summary

Problems solved by technology

Thus, the pushing movement prevented by these elastic elements and the wear of elements no longer needed here are transferred to wear on the shuttle path and to the linear guide elements arranged obliquely to the vertical with respect to the drive beam, as well as by the link The spring elastic elements on the shuttle embroidery machine cause inherently harmful vibrations
