Abstract
A method of making sliding clasp fasteners having interlocking wire helices comprises heating helical wires of thermoplastics material to a first temperature ensuring their approximate dimensional stability, sewing the stable helical wires to stringer tapes made of synthetic fibres by means of a synthetic thread, the synthetic thread and synthetic fibres being of thermoplastics material and finally heating the resultant fasteners at a temperature near but below the softening temperature of the or at least one of the thermoplastics material. The helical wires sewn to two stringers may be interlocked before the second heating operation. In one embodiment the same thermoplastics material, e.g. a polyamide or polyester, is used for the thread, wires and stringers. In alternatives, the stringers are made of a thermoplastics material having a higher melting temperature than the thermoplastics material of the wires and thread, and the stringers can be heated to the first temperature before the helical wires are sewn on. During the second heating operation, the convolutions of the wires shrink, the wires thicken, the thread shrinks and thickens, and the stringers shrink and thicken thus forming a strong anchorage of the helical wires to the stringers. Also the clearance between adjacent interengaging locking members is reduced to obtain better interlocking. The second heating operation may be carried out either in dry conditions, e.g. by high-frequency, hot air or laser beams, or in moist conditions e.g. in or above a bath of high-temperature liquids, e.g. liquid salt or metal, which liquid is soluble in water. Nylon may also be used for the thread and stringers. Reference has been directed by the Comptroller to Specification 997,612.
