ABSTRACT:
A method for stamping a monofilament between a pair of mating stamping rollers to form shaped portions for slide fastener coupling elements includes using an annular outer roller and a cylindrical inner roller with pressing projections on a mating stamping surface of at least one of the rollers. The rollers are positioned in such an arrangement that an outer circumferential surface of the cylindrical inner roller mates partially with an inner circumferential surface of the annular outer roller. The rollers are rotated in a common direction, and monofilament is supplied continuously to an area where an inner circumferential surface of the annular outer roller and an outer circumferential surface of the cylindrical inner roller mate. The monofilament is thereby pressed for a longer time in order to form accurately coupling head portions of slide fasteners.
