Abstract

1,206,536. Moulding slide fasteners. TEXTRON Inc. 11 April, 1968 [17 Nov., 1967], No. 17724/68. Heading B5A. [Also in Division D1] Coiled filaments for slide fasteners are made by rotating an offset member 2 round a stationary support 4 which carries a needle-like mandrel 5 having a rectangular cross-section so that the filament F is drawn from a source of supply and coiled around the mandrel. The filament is tensioned as it is wound around the mandrel so that it is subjected to a greater tension during one part of the revolution than another part so as to deform the filament at spaced-apart intervals to form a crown portion (see Fig. 9) in each convolution of the coiled filament. As shown, a pair of coiling devices are mounted side by side with the needle-like mandrels being adjacent and feeding the coiled filament into a circumferentially grooved forming wheel 6, the filaments, e.g. nylon, can be heat-set in the forming wheel.
