Belt structure of the green tire, manufacturing methods and equipment of the belt package and crown structure

摘要

Immediately upstream of the (13, 14) of one assembly drum 1, (113a, 113b) is at least substantially continuous belt strip a method and equipment for manufacturing a belt structure of the green tire, make up the belt structure method and equipment are made by is disclosed. And equipment This method is integrated in each and the method and the equipment for producing the crown structure and belt package incorporating a belt structure thus been acquired. In the manufacturing method of the belt package, while formed on the belt structure of the rubber composition layer incorporating a plurality of reinforcing cords (104), in the method of manufacturing the crown structure, over the belt package thus formed I assembled tread (105) to. Rubber mixture layer incorporating (104) the reinforcing cords and immediately upstream of the (18) assemblies one drum, both are manufactured by at least substantially continuous tread (105). It is possible therefore, the advantage of maintaining a high belt structure and the stable quality of the belt package can be obtained, to simultaneously achieve an improvement of the production capacity of the equipment and reduction in manufacturing costs.
