发明名称 COUPLING ELEMENT FOR SLIDE FASTENER AND METHOD OF MANUFACTURE
摘要 A coupling element, such as a scoop formed from a synthetic polymer, for a slide fastener includes a head with a triangular side cross section bounded by a top surface and two downwardly converging bottom surfaces which extend at equal angles relative to legs of the coupling element. Leg sections adjacent the head are disclosed as being formed with oriented polymer for increased strength.
