Abstract

In a tire vulcanizer (1) having two sets of portions, each of which includes a lower mold (2), an upper mold (3), and a center mechanism (4L, 4R) provided with a bladder (B), a nitrogen gas heated in a first heating device (11) is supplied to an interior of the bladder of the center mechanism (4L) which is placed on the upstream side in the circulating direction of the nitrogen gas. The nitrogen gas discharged from the interior of the bladder of the center mechanism (4L) is used for vulcanization and patterning and a temperature thereof is lowered. However, this nitrogen gas is heated again in a second heating device (31), so that the temperature is increased. Therefore, the nitrogen gas heated in the second heating device (31), is supplied to an interior of the bladder of the center mechanism (4R) which is placed on the downstream side in the circulating direction of the nitrogen gas.
