ABSTRACT:
A method for vulcanizing an elastomer product includes heating under pressure an elastomer product placed in a mold by supplying a heating medium such as steam, stopping the supply of the heating medium when the elastomer product rises to a predetermined temperature or after the lapse of a specified period of time, supplying a pressurizing medium such as nitrogen gas at a pressure equal to or higher than that of the heating medium until the heating process is completed, and discharging the vulcanizing medium after the heating process. The heating and pressurizing medium are supplied through respective blow supply means with the heating medium being blown to a lower portion of the vulcnizing chamber and the pressurizing medium being blown to an upper portion of the vulcanizing chamber.
