发明名称 Process for manufacturing, moulding and curing tyres for vehicle wheels
摘要 A process for manufacturing, moulding, and curing a tire includes the steps of manufacturing a tire comprising a first elastomer material, providing an inner surface of the tire with a treatment to prevent permeation of a fluid under pressure through the treatment, closing the tire into a moulding cavity defined in a vulcanization mould, admitting a fluid under pressure into a space defined by the treatment in order to press an outer surface of the tire against the at least one wall of the moulding cavity, and applying heat to the tire to vulcanize the first elastomer material. A shape of the at least one wall of the moulding cavity matches a shape of the outer surface of the tire after vulcanization is complete. The treatment includes at least one layer of a second elastomer material having a sulfur-curable polymeric base and a vulcanizing system dissolved in an organic solvent.
