An apparatus and a method of manufacture for a tire component comprising a sheet of reinforced unvulcanized rubber compound having two parallel main surfaces comprising pre-coating the reinforcement material fabric of the component with unvulcanized rubber compound, placing the component in an open mould shaped to accommodate the component arranged to contact one of said surfaces, positioning a pressurizing member to contact the other said surface, maintaining the time/temperature conditions of the mould and the component below those required to cause vulcanization, operating the pressurizing member to apply substantial compressive force to the component so that the rubber compound is pressed into intimate contact with the reinforcement and removing the unvulcanized component from the mould. The method provides real penetration of the rubber compound into the reinforcement and is particularly valuable for tire breakers which are steel cord reinforced. The breakers may be made as annular rings or straight discrete lengths.
