ABSTRACT:
Slide fastener elements made of a helically wound synthetic resin monofilament and the method of forming the same. According to a preferred embodiment, each fastener element comprises an interengaging head arranged on one-line in the longitudinal direction of the slide fastener elements, a pair of interengaging head-side widened portions formed at the both sides of the interengaging head, upper and lower legs extending from the both ends of the interengaging head through the pair of interengaging head-side widened portions respectively so as to transverse the longitudinal direction of the slide fastener elements and a turn extending between an upper leg of one slide fastener element and a lower leg of an adjacent slide fastener element through a pair of connecting portions formed at the both sides of the turn. The interengaging head is formed by pressing the monofilament to be sidened at its portion corresponding to the interengaging head. The interengaging head-side widened portions and the connecting portions are formed by pressing the monofilament to be widened adjacent to the head and the turn respectively and used as the bending portions of the monofilament into the slide fastener elements made of the helically wound monofilament.
