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: A waist part cloth guiding device for a sewing machine comprises a guide which folds and guides a side edge portion of a cylindrical cloth to enclose a ring band ahead of the needle drop point, while feeding the band together with the cloth in a cloth feed direction by a forced feeding device, regardless of the operation of a main shaft of the sewing machine. After setting the ring band to be inserted into the folded portion of the cylindrical cloth at a position close to the needle drop point of the sewing machine, the side edge portion of the cylindrical cloth may be automatically guided and folded to the lower side of the ring band.
