    摘要： When a green tire (4) is molded on a bladder (20) in molding step and then carried into the mold of a vulcanizer in vulcanization step to vulcanization-mold the green tire, the upper bead (4c') and lower (4c) bead of the green tire (4) are connected and fixed through a center post (22) as they are retained by the bladder (20) kept in the airtight state by an upper ring (19) and a lower ring (14) until the molded green tire (20) has been carried into the mold of the vulcanizer, and a pressure gas is sealed into the bladder (20) located in the internal space of the green tire (4) to lay it in the expanded state, whereby the green tire (4) 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 (4) can be prevented, and the slippage of supporting center of the green tire (4) when set in the vulcanizer can be sufficiently reduced.

    摘要： A raw tire preheating device comprises tread section preheating mechanism (16) consisting of a front coil (21) disposed in opposed relation to a tread section (4a) for producing a high frequency magnetic field and applying it to the tread section (4a), and of a core mechanism having center cores (24), separation cores (25) and side cores (26) that are made of a material containing a ferromagnetic low electric conductivity material for pulling in the high frequency magnetic field and that set the high frequency magnetic filed in such a distribution as to uniformly preheat the whole of the tire widthwise area of the tread section (4a), and a mechanism for moving at least either the tread section preheating mechanism (16) or the raw tire (4).
