ABSTRACT:
An auxiliary transport device for sending out workpieces sewn on an elastic tape by a sewing machine is composed of front and rear rollers and a belt transmission device, and a cutter between the rollers, and one of the rollers is rotated and driven in synchronism with the sewing machine. A belt of the belt transmission device transmits the rotation of one roller to the other roller and works to transport the workpieces while pressing and flattening them on the cloth feed surface, and prevents the end of workpieces from curling up due to shrinkage of the tape when the tape is cut, thereby leading the end smoothly to the rear roller.
