Abstract

1,257,017. Centrifugal casting. DUNLOP HOLDINGS Ltd. 29 Jan., 1969 [6 Feb., 1968], No. 5860/68. Heading B5A. In the centrifugal casting of pneumatic tyres a plurality of fibres are applied to a mould surface, e.g. by electrodeposition, on the surface of an adhesive coated segmental mould core, and the casting material is then supplied to the mould. In addition to the fibres other reinforcement layers, e.g. parallel cords of rayon or reticulated polyurethane foam, may be provided. The cords are wound on a frame which -holds the bead wires apart and the core is located in the cage structure so formed. Where more than one additional reinforcing layers are used, intermediate spacing layers of polyurethane foam are provided. The inner surface of the mould may also be flocked with fibres. The reinforcement may 'comprise metal tapes, metal wires, textile cords or woven textile fabrics.
