TIRE VULCANIZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a tire vulcanizing method capable of minimizing the consumption amount of a nitrogen gas used for cooling the inside of a bladder while shortening a cooling cycle time and a vulcanizing cycle time and capable of suppressing the seasonal fluctuations of them to stably vulcanize a tire. SOLUTION: In the tire vulcanizing method, the bladder 4 is inserted in the unvulanized tire 3 set to a mold 2 and a high temperature gas is supplied into the bladder 4 to vulcanize the unvulcanized tire 3. The cooling nitrogen gas adjusted to a definite temperature of 20°C or below is introduced into the bladder 4 in the latter half of the vulcanization of the unvulcanized tire 3.
