发明名称 Tire structural member manufacturing method
摘要 A cord-reinforced band 2 having at least one cord 1 is cut into a plurality of cord-reinforced strips 3 of a predetermined length L. The cord-reinforced strips 3 are arranged successively such that side edge parts of adjacent cord-reinforced strips 3 overlap each other and the adjacent cord-reinforced strips are bonded together to form a tire structural member of a pre-determined length with respect to a direction perpendicular to the longitudinal side edges of the cord-reinforced strips 3. The tire structural member manufacturing method uses one and the same extrusion die 14 having an extrusion opening of a fixed width regardless of a pitch at which the cords 1 are arranged. Thus, the tire structural member manufacturing method is simpler.
