Lynlås med skruelinieformede låseledrækker af en formstofstreng.

摘要

A slide fastener comprises a synthetic-resin monofilament formed into undulations or turns and attached by a chain stitch to the support tape at only the legs lying along this tape. These legs are embraced by the stitches which are in part shielded by the remainder of the coupling element. The stitches may simultaneously form a filler cord and may be locked in place by clamping of the shanks of the coupling element thereagainst.
