METHOD AND DEVICE FOR MANUFACTURING TIRE CONSTITUTIONAL ELEMENT
Document Type and Number:
Japanese Patent JPS6036145
Kind Code:
A
Abstract:
An apparatus and a method of manufacture for a tyre component comprising a sheet of reinforced unvulcanised rubber compound having two parallel main surfaces comprising pre-coating the reinforcement material fabric of the component with unvulcanised rubber compound, placing the component is an open mould shaped to accommodate the component arranged to contact one of said surfaces, positioning a pressurising member to contact the other said surface, maintaining the time/temperature conditions of the mould and the component below those required to cause vulcanisation, operating the pressurising 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 unvulcanised component from the mould. The method provides real penetration of the rubber compound into the reinforcement and is particularly valuable for tyre breakers which are steel cord reinforced. The breakers may be made as annular rings or straight discrete lengths.
