Sliding clasp closure - has coupling elements with side grooves for weft binder from support ribbon to confer stability without stiffness

摘要

The sliding clasp closure comprises woben support ribbons holding the rows of coupling elements contain eyeholes and are formed of thermoplastic material. They have branch sections joined by an area of welding, and are arranged in a row of a continuous support strand comprising strings or monofilaments. Between the coupling elements the support strand is held by binding yarns which are the weft yarns of the corresp. support ribbon. The coupling element branches have grooves on their sides which deepen towards the support ribbon to which the elements are attached. The binding weft yarns may pass into the grooves at the edge of the ribbon fabric. The arrangement provides a sliding clasp closure having coupling elements with complete stability to torsion, without displaying any trouble some stiffness.
