ABSTRACT:
A slide fastener stringer comprises a stringer tape and a row of continuous meandering fastener elements fixed by sewing threads to one longitudinal edge of the tape, the elements being reinforced by a braid mounted on and extending along the element row. The slide fastener stringer has a cut edge where the tape, extreme one of the fastener elements, sewing threads, and braid, all including thermoplastic synthetic resin material, are fused together against raveling of the cut ends of the tape, sewing threads, and braid, and against sticking up of the element from the tape. The extreme fastener element has a pair of upper and lower legs one on each side of the tape, the legs being wrapped jointly by the sewing threads and stringer tape that are fused together and with the upper and lower legs. The braid is fused with portions of the sewing threads and stringer tape which extend beyond and around the extreme fastener element.
