ABSTRACT:
An apparatus for carrying unvulcanized pneumatic tires in a tire vulcanizer, comprising: a plurality of upper arcuate segments disposed substantially within a cylindrical surface, each of the upper arcuate segment having at its lower end an upper bead support end for supporting an upper bead portion of the unvulcanized pneumatic tire and a plurality of lower arcuate segments disposed within the upper arcuate segments, each lower arcuate segment having rotatably mounted at its lower end a lower bead support member for supporting a lower bead portion of the unvulcanized pneumatic tire and being movably supported by the corresponding upper arcuate segment. The upper arcuate segments are expandable and contractable radially inward and outward together with the lower arcuate segments. Each of the upper and lower arcuate segments are movable toward and away from with each other and overlapped with each other when moved toward each other.
