PROBLEM TO BE SOLVED: To prevent a bladder from being damaged locally while improving the uniformity of temperature distribution in the bladder of a tire vulcanizing apparatus. SOLUTION: The bladder 20 is expanded in a green tire stored in a vulcanizing mold, and steam S is spouted from a plurality of exhaust nozzles 43 into the bladder 20 to be supplied. The ejection direction of the steam S in the exhaust nozzles 43 is turned to a center post 30. The steam S spouted from the exhaust nozzles 43 is made to collide against the center post 30, diffused in the prescribed direction, and supplied into the bladder 20. The steam S which is prevented from being spouted directly to collide against the bladder 20 is spouted from each exhaust nozzle 43 toward the same circumferential side of the bladder 20, and the spiral flow of the steam S is generated in the bladder 20. The green tire is heated to promote vulcanizing molding. COPYRIGHT: (C)2010,JPO&INPIT |
