Abstract

This invention relates to a method and device of ribbon splicing, which can eliminate bad condition controlled by the tension induced by stitch number to splice a ribbon to the blank, no need of detection of action amount of sewing machine. The length dimension of ribbon(3) is set corresponding with tension, when the ribbon(3) is spliced to the blank (2), the feed level and tension of the ribbon(3) are detected. During feeding the ribbon(3) of preset length, the corresponding tension is applied on the ribbon(3). Thus, the tension is controlled by feed level of the ribbon(3) of the sewing machine (4), not by the action amount of the sewing machine (4) of rotational velocity of driving shaft, stitch number.

Description

technical field [0001] The present invention relates to a method and a device for sewing ribbons to gray fabrics. Background technique [0002] In a product constructed by sewing a ribbon to the gray fabric, there are parts where you want to sew while applying tension to the ribbon for processing to shrink the gray fabric after sewing, and for processing to make the fabric shrink after sewing. A product where the gray fabric becomes flat without applying tension to the ribbon to seam the part. In the case of sewing such a product, each part is divided into a plurality of processes, the tension and the number of stitches are set for each process, and the belt-shaped Apply the corresponding set tension to the object, and at the same time sew the ribbon to the gray fabric. Such a prior art belt sewing method is disclosed, for example, in JP-A-62-213789. [0003] As in the belt sewing method disclosed in Japanese Unexamined Patent Publication No. 62-213789, in a structure tha...
