ABSTRACT:
A taped chaining thread sewing device is designed to sew by operation of an overedge sewing machine a tape into the upper surface of the fabric sent into the needle location of the sewing machine, and also sew the chaining thread cut off from the preceding fabric into the lower surface of the fabric. The tape is cut off together with the unnecessary edge portion of the fabric by a cutter at the start of sewing of the leading end from the sewing part on the fabric. Before the final end of the fabric passes the cutter, a tape guide of the taped chaining thread sewing device moves, and therefore the unsewn portion of the tape is cut off together with the unnecessary edge portion of the fabric from the sewn part by the cutter. By the chaining thread sewn into the beginning part of sewing of the fabric, it is not necessary to perform any particular bar tacking job at the beginning of sewing in a separate process. By properly setting the timing by which movement of a holding part of a chaining thread processing device is effected in the direction crossing the fabric, the length of the chaining thread to be sewn in may be set to a specific length.
