摘要： Disclosed is a tire vulcanising press wherein a plurality of sectors provided for gripping the upper bead of a green tire loaded in position between a pair of upper and lower die elements to carry the green tire in a suspended condition will not form an obstruction to an elastic forming member for shaping. The tire vulcanizing press includes an inner cylinder mounted for up and down movement on the upper die element and having at a lower end portion thereof a bead ring which is capable of forming part of the upper die element, and a sector housing mounted for up and down movement in the inner cylinder and carrying thereon the sectors for movement between an open position and a closed position. The upper bead of the green tire can be gripped between the bead ring and sectoral portions of the sectors, and the sectoral portions of the sectors are accommodated in the lower end portion of the inner cylinder when the sectors are in the closed position. Also a ring fitting portion is provided for receiving and retaining therein during vulcanization an upper mounting ring on which the elastic forming member is provided.
