IPC: D05B29/00
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent a small cloth piece from wrinkling even when a small piece sewing part is folded in by a method wherein the surface of a cylindrical cloth is brought into contact with the small cloth piece placed on a feed plate to be held so that it can be sewn with a sewing needle from the side of the internal surface thereof. SOLUTION: A small piece cloth keep plate 16 is protruded from a feed plate carrier part and a worker sets a small cloth piece being pinched under a protruded part of the small cloth piece keep plate 16. A keep plate 5 and a keep 7 are driven integral in X-Y pinching a shoe sole cloth and a hem end of slacks on a plane. The shoe sole cloth is sewn contacting the lower external surface of the hem end of the slacks by a vertical drive of a sewing needle 9 from the inside of the hem end of the slacks. In this manner, the external surface of the slacks is brought into contact with the top surface of the shoe sole cloth to be sewn by a sewing needle 9 from the inside of the slacks. This enables preventing of the shoe sole cloth of the hem end from being wrinkled when a part having the shoe sole cloth sewn thereon is folded in.
