Abstract

1,049,761. Moulding sliding clasp fasteners. J. C. SIEGRIST. Feb. 7, 1964 [Feb. 21, 1963], No. 6936/63. Heading B5A. In method of moulding sliding clasp fasteners, two tapes 16 are drawn between dies 1 and 2, the dies closed, and plastics material injected into mould cavities 6 and 7 around the beaded edges of the tapes. During the moulding a T- shaped member 12, slidable in the lower die 2, is urged by a spring downwards on to a retracted wedge member 18. Upon withdrawal of the upper die the wedge member 18 is released and moves, under the action of a spring, to the position shown in Fig. 4 thus raising member 12 and freeing the formed fastener from the lower die. The formed fastener is then removed and a further length of tape introduced between the dies by the apparatus of Figs. 1 and 2 (not shown).
