TIRE PREHEATING APPARATUS, TIRE VULCANIZATION SYSTEM, TIRE PREHEATING METHOD, AND TIRE MANUFACTURING METHOD

WIPO Patent Application WO/2016/129112

A1

A tire preheating apparatus (50) according to the present invention is provided with: an outer preheating section (51) that surrounds the outside of a green tire (40X) having an easily-vulcanized region (A2) and a hardly-vulcanized region (A1) and heats the green tire (40X) to room temperature or more from the outer surface side of the green tire (40X) at temperature less than temperature at which a vulcanization reaction is accelerated in the green tire; and an inner preheating section (54) that is disposed inside the green tire (40X) and heats the green tire (40X) to the room temperature or more from the inner surface side of the green tire (40X) at temperature less than the temperature at which the vulcanization reaction is accelerated in the green tire (40X). The outer preheating section (51) has a first tire heater (52) that heats the outer surface of the easily-vulcanized region (A2) and a second tire heater (53) that heats the outer surface of the hardly-vulcanized region (A1) at a heating value higher than that of the first tire heater (52).
