Abstract: An automatic hemming apparatus for supplying a tubular workpiece in an adequate attitude to a sewing machine (4) is disclosed. The apparatus has a workpiece position control device (21) and a guide (19) for folding a circular edge of the workpiece in front of a sewing bed (6). The sewing machine (4) is provided with a delivery roller (10) at the rear side and an assisting feed belt (26) at the outside of the sewing bed (6). The device (21) comprises an edge sensor (17) and inclined freely rotatable rollers (22A to 22D) so as to contact with the workpiece on the outer surfaces thereof. On the feeding operation of roller (10) and belt (26), according to a signal from the sensor (17), a stepping motor (24) changes the inclining direction of the rollers (22A to 22D) and the workpiece is moved toward the right or left.

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.
