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.
