Embodiment Construction

[0032] 1 to 5 are explanatory diagrams showing the configuration of main parts of a single loop stitch button sewing machine (hereinafter simply referred to as a sewing machine) according to this embodiment.

[0033] This sewing machine is a sewing machine called a cycle sewing machine, which is driven by one cycle of a mechanism that rotates a rotating body having an eccentric rotating shaft to perform predetermined single-loop sewing for sewing buttons on an object to be sewn, and at the same time Has a mechanism for seam handling after buttons are sewn.

[0034] Incidentally, in the sewing machine of the present embodiment, as the thread processing after the button sewing is completed, there is a structure that can switch between the cutting processing and the pulling processing. After the stitches form knots, the aforementioned movable cutters are moved to cut the aforementioned stitches. The breaking process is to apply tension to the stitches after the stitches are knott...

Abstract

The present invention provides a single-ring sewing machine for sewing button, which is arranged with the following structure: the sewing machine can ensure the sewing treatment of the sewing machine during button sewing to correspond to requirement, and can switch between the condition of forming line head and non forming line head. The sewing machine is arranged with a structure for switching cutting treatment and snapping treatment. The cutting treatment is that to cut off the suture by the motion of a movable cutter (93) after the suture forming a line knot when finishing button (121) sewing; the snapping treatment is that to snap the line knot part by means of a strain applied on the suture after forming a line knot when finishing button (121) sewing.

Description

technical field [0001] The present invention relates to a single loop stitch button sewing machine, which has a structure capable of switching a sewing thread processing unit after button sewing. Background technique [0002] At present, in single-loop button sewing machines that do not have a cutter for thread cutting, for example, by pulling the thread after forming a knot at the final stage of button sewing, the tension acting concentratedly on the above-mentioned knot portion is utilized. And pull off suture, carry out tangent. [0003] However, since in the method of pulling the suture at the knot portion, the suture is broken at a portion very close to the knot, so almost no thread ends (threads from the knot to the thread end) are formed. Therefore, when the knot tightness is poor or the knot tightness becomes loose due to friction or the like, there arises a problem that the suture thread is likely to come apart. [0004] Therefore, the single-ring stitch button se...
