摘要： A hollow-cylindrical portion (26) inserted in a hollow-cylindrical portion (16) of one rim section (12) is provided on the other rim section (13). To form a split rim (11), part (head portion) of the inner hollow-cylindrical portion (26) overlaid on the outer hollow-cylindrical portion (16) is radially outwardly expanded by being elastically deformed by a tapered surface (39) of a piston (38) such that the inner and outer hollow-cylindrical portions (16, 26) are in close contact with each other. As a result, relative positions of the rim sections (12, 13) are strictly defined, and this enables high assembling accuracy, particularly coaxiality with a high level, to be achieved. A fine fitted to the split rim (11) can be inspected with high accuracy.

摘要： With a tire vulcanizing system, a transfer device (4) for receiving a vulcanized tire K from a vulcanizer (1), and transferring the same to a post-cure inflator (2) to be delivered to a rim (21) of the post-cure inflator (2) is provided with a pair of gripper fingers (19A, 19B) for rotatably gripping the vulcanized tire K. The transfer device (4) holds the vulcanized tire K with the pair of gripper fingers (19A, 19B), and transfers the vulcanized tire K to the top of the rim, thereby rotating the same to a position where a rim-fitting peak value of the rim coincides with an RFV peak value of the vulcanized tire to be then placed on top of the rim before executing processing in the post-cure inflator (2).

摘要： A method of highly efficiently producing pneumatic tires, wherein both bead portions (B) of a green tire (G) are supported by a pair of holders (24, 50) and opposite axial ends of a bladder (25) are tightly attached to the holders (24, 50), respectively. The holders (24, 50) are joined to each other and a fluid is supplied into the bladder (25), to preliminarily inflate the bladder (25) within the green tire (G). The green tire (G) is transferred into a vulcanizer, together with the holders (24, 50) and the preliminarily inflated bladder (25). A heat medium is supplied into the bladder (25), to vulcanize the green tire (G) and form a vulcanized tire (K). The preliminary inflation of the bladder (25) at a location outside of the vulcanizer eliminates or shortens the waiting time within the vulcanizer, thereby improving the overall work efficiency and productivity at a tire factory.

摘要： A method and apparatus for vulcanizing tires are provided. An unvulcanized tire is transferred and loaded onto a lower mold member when a plurality of arcuate sector mold members aligned along the peripheral direction locate at the radially outermost positions as well as upper ends of the sector mold members incline radially outwards about their lower ends. An upper mold member moves toward the lower mold member while the sector mold members are swung about their lower ends to straightly stand the sector mold members, and the sector mold members are then synchronously displaced radially inwards, so that the unvulcanized tire is hermetically enclosed in a mold space formed by these mold members. The unvulcanized tire is vulcanized within the mold space to give a vulcanized tire. The sector mold members are synchronously displaced radially outwards, and swung such that the upper ends incline radially outwards about the lower ends while the upper mold member is moved away from the lower mold member, so as to remove the vulcanized tire out of the mold.
