Manufacturing equipment of the production method and the pneumatic tire of a pneumatic tire

摘要

Two extruders are located at positions which are mutually shifted by 180 degrees around a rotation shaft of a rotary support, and are arranged at the same position in the rotation shaft direction of the rotary support, and each time the rotary support is rotated 180 degrees, the two extruders and the rotary support are caused to relatively move in the rotation shaft direction of the rotary support. In this manner, at least a portion of the pneumatic tire is molded by winding the rubber strip members onto the rotary support.
