KEDJA AV KONTINUERLIGA KOPPLINGSELEMENT FOR DRAGKEDJOR SAMT SETT FOR DESS FRAMSTELLNING

摘要

A row of continuous slide fastener coupling elements is in the form of a filamentary coil or zigzag made of thermoplastic synthetic resin. Each coupling element includes a coupling head, a pair of legs extending from the coupling head, and a connector located remotely from the coupling head and extending between one of the legs and a leg of an adjacent coupling head. The connector is heat-set intensely by being heated concentratedly for increased dimensional stability. A method of manufacturing a row of such continuous slide fastener coupling elements includes the step of heating the connectors at a temperature close to the melting point of the monofilament.
