Abstract

873,664. Moulding zip-fastener elements &c. LIGHTNING FASTENERS Ltd. May 18, 1960 [June 12, 1959], No. 20173/59. Class 87(2). Apparatus for moulding continuous toothed strip, e.g. part of a zip-fastener, comprises a stationary feeding element 7 provided with a passage 8 for the injection of plastic material such as nylon therethrough, and a rotatable member 1 having a succession of mould cavities 3 connected by a groove 4; member 1 being so disposed in contact with element 7 that when rotated the cavities are successively aligned with passage 8. Element 7 may carry a rib to engage in the groove to prevent injection before the member 1 is correctly aligned with passages 8 and the element 1 may have its lower face designed to produce a rib on the strip. Element 7 extends over several mould cavities and in Fig. 2, (not shown), is applied over the cavities in the curved periphery of the rotatable member.
