Abstract
An apparatus for manufacture of a tire component said component being a sheet of reinforced unvulcanized rubber compound having two parallel main surfaces. The apparatus comprises an open mould shaped to accommodate the component arranged to contact one of said surfaces, a pressurizing member to contact the other said surface, and apparatus for maintaining the time/temperature conditions of the mould and the component below those required to cause vulcanization. The pressurizing member applies substantial compressive force to the component so that the rubber compound is pressed into intimate contact with the reinforcement. The apparatus provides real penetration of the rubber compound into the reinforcement and is particularly valuable for tire breakers which are steel cord reinforced.
