Abstract

1,246,471. Centrifugal casting. DUNLOP HOLDINGS Ltd. 29 Jan., 1969 [6 Feb., 1968], No. 5861/68. Heading B5A. [Also in Division B7] A method of centrifugally casting a reinforced article, e.g. a tyre, in a mould comprises positioning in said mould a reinforcement and at least one element of open structure material of such form as to allow passage therethrough of casting material, said element being positioned securely against at least one moulding surface of said mould and supporting the said reinforcement in spaced relationship from the moulding surface during casting, feeding sufficient liquid casting material to said mould to form the said article and fill the open structure of the said element, and rotating the mould. The reinforcement and spacing element, e.g. a reticulated polyester polyurethane foam or a crimped filament web of nylon, are assembled prior to positioning in the mould. The element may comprise a metal-plated reticulated foam. The reinforcement comprises a layer of parallel cords, between two spacing elements 2a and 2b. In the moulding of a tyre the assembly is formed into a cylinder and bead cores 3a, Fig. 2, are located at each end before distending the cylinder on the core of the tyre mould which during rotation receives liquid polyurethane.
