Abstract

The root winding button sewing machine has one pair of holding parts, which are configured in the interval to form opening wider than the specified swing amplitude to make the needle form root winding stitch; one pair of guide parts, which may be assembled in or disassembled from the opening to hold the cloth together with the holding parts and are configured in the interval to form the threading part for the root thread to pass through and with interval narrower than the specified swing amplitude; and one controller, which controls the driving units so as to locate the needle for forming root winding stitch. The root winding button sewing machine is suitable for sewing button to knitwear and other cloth with easy elongation through root winding sewing to ensure high sewing quality.

Description

technical field [0001] The invention relates to a sewing machine for sewing buttons around the root and a button sewing method using the sewing machine for sewing buttons around the root. Background technique [0002] Known thread-wound button sewing machines in the past sew buttons on the cloth, and then wind the upper thread around the root thread (sewing thread) between the button and the cloth to form the thread (for example, refer to Patent Document 1). [0003] When sewing buttons to fabric with a wrap around button sewing machine, if Figure 9 ~ Figure 11 As shown, the cloth 116 is set in a state of covering the front end 111 a of the tongue-shaped member 111 , and the front end 111 a of the tongue-shaped member 111 is brought close to the support base 112 while maintaining this state. In the vicinity of the support table 112, a tongue sensor (not shown) is provided. By detecting the front end 111a of the tongue 111 with the tongue sensor, the tongue 111 can be driven...
