摘要： A center mechanism of a tire vulcanizer is provided with a screwing mechanism provided with a screw shaft and a screw nut screwed onto the screw shaft, a motor for rotating the screw shaft so as to raise and lower an upper ring body, an inverter for controlling the motor, and a mechanical brake for retaining a predetermined position of the upper ring body so that a bladder retains a shaping state. Within a time range from start of a closing action of the upper die to contact between the upper die and the upper ring body, an operation of the mechanical brake is released and position control of the upper ring body by the inverter is started, and at least after the release of the operation of the mechanical brake, a position of the upper ring body is controlled by the inverter. By such a configuration, even when there is an erroneous operation of the brake or incorrect setting, it is possible to prevent damage and breakage of constituent parts and have a simple structure.

摘要： In a post-cure inflator of the present invention, a rim of a pair of disk shape rims for sandwiching bead portions of a tire has one rim surface and the other rim surface in which a plurality of step portions corresponding to the bead portions of different bead diameters are formed so as to reduce thickness from a center to an outer periphery. A pair of the rims is supported switchably between arrangement in which the one rim surfaces face each other and arrangement in which the other rim surfaces face each other. By such a configuration, it is possible to favorably sandwich the tire even when the bead diameter to be treated is added.

摘要： When a green tire is molded on a bladder in molding step and then carried into the mold of a vulcanizer in vulcanization step to vulcanization-mold the green tire, the upper bead and lower bead of the green tire are connected and fixed through a center post as they are retained by the bladder kept in the airtight state by an upper ring and a lower ring until the molded green tire has been carried into the mold of the vulcanizer, and a pressure gas is sealed into the bladder located in the internal space of the green tire to lay it in the expanded state, whereby the green tire can be carried between the steps and carried into the mold in the state maintaining a fixed shape. Accordingly, the deformation of the green tire can be prevented, and the slippage of supporting center of the green tire when set in the vulcanizer can be sufficiently reduced.
