A vulcanization apparatus provided with a vulcanization vessel for vulcanizing a green tire and a suction line for sucking out gas from inside the vulcanization vessel after the vulcanization vessel has been opened. Accordingly, oily smoke generated when vulcanized rubber has been removed from a bladder and an inner wall of a mold can be more efficiently discharged than in cases in which gas inside a vulcanization vessel is sucked out and additional air is introduced into the vulcanization vessel only prior to opening the vulcanization vessel.

Vulcanized tire manufacturing method and vulcanization apparatus

A pneumatic tire production system comprises production lines each including a green tire building station for assembling unvulcanized members of pneumatic tires into green tires. The green tires are vulcanized at a vulcanizing station which includes at least one vulcanizing unit equipped with a plurality of vulcanizing molds. The number of the vulcanizing mold is determined so as to satisfy the vulcanizing capacity which is substantially equivalent to the number of green tires formed at the building station within a predetermined unit time. The system serves to minimize the intermediate stock amount of green tires due to minimized changeover between different types of tires to be alternately produced.

Production system for pneumatic tires

A vulcanizing system including a tire transferring apparatus or a mold opening/closing station arranged equidistantly to a plurality of vulcanizing stations, thereby achieving a reduced equipment cost and a reduced installation space with a higher manufacturing efficiency.

Tire vulcanizing system and tire manufacturing method to be used therefor

A mold exchanger system includes a transfer device for transferring a mold into, and from a vulcanizing machine. The transfer device has a height adjusting mechanism for adjusting the transferring height of the mold, and a positioning mechanism for positioning the mold relative to the vulcanizing machine. The mold exchanger system has a simplified structure and yet allows the mold to be precisely centered and positioned relative to the vulcanizing machine, and to be smoothly transferred into, and removed from the vulcanizing machine, and significantly reducing the transfer time and the removing time to thereby improve the mold exchanging efficiency.
