<P>PROBLEM TO BE SOLVED: To improve economical efficiency in a twin type tire vulcanizer. <P>SOLUTION: A nitrogen gas heated in a first heating device 11 is supplied to the interior of a bladder B of a 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 B 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. Accordingly, the nitrogen gas heated in the second heating device 31 is supplied to the interior of the bladder B of the center mechanism 4R which is placed on the downstream side in the circulating direction of the nitrogen gas. <P>COPYRIGHT: (C)2013,JPO&INPIT |
