Abstract
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 predetermined 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.
Claims4
A tire structural member manufacturing method of manufacturing a tire structural member of a predetermined length, said tire structural member manufacturing method comprising the steps of:
- cutting a cord-reinforced band having at least one reinforcing cord into a plurality of cord-reinforced strips of a predetermined length;
- and
- successively arranging the cord-reinforced strips such that side edge parts of adjacent cord-reinforced strips overlap each other and bonding the adjacent cord-reinforced strips together;
- wherein the cord-reinforced band has a fixed width regardless of pitch at which the reinforcing cords are arranged in the tire structural member.
