PNEUMATIC RADIAL TIRE PRODUCION METHOD AND BELT TREAD ASSEMBLY TRANSFER APPARATUS USED FOR THE SAME

摘要

A pneumatic radial tire production method and a belt tread assembly transfer apparatus used for the method. The production method enables to improve uniformity of a tire and to prevent a separation failure caused by trapped air. A pneumatic radial tire production method including steps of forming a primary green tire including carcass layers, forming a hollow-cylindrical belt tread assembly including belt layers, transporting the belt tread assembly to the outer peripheral side of the primary green tire by a transfer apparatus, and adhering by pressing the belt tread assembly to the primary green tire inflated in a toroidal shape, wherein the primary green tire and the belt tread assembly are adhered by pressing while the transfer apparatus restraining both side sections of the belt tread assembly and at the same time inflation of a center section is being allowed.
