Abstract
A method and an apparatus for vulcanizing an elastomer product, such as automobile tires, wherein the elastomer product is placed in a vulcanizing chamber in a mold steam at an elevated pressure is supplied to the vulcanizing chamber to heat and pressurize the elastomer product until the elastomer product reaches a prespecified temperature or for a prespecified period of time, the steam supply is stopped and a pressurizing gas, at a pressure not lower than the steam supply pressure, is supplied to the vulcanizing chamber until the end of a heating period, said steam being blown in and supplied from an upper position of the center of the vulcanizing chamber in a horizontal direction or in an inclined downward direction, said steam being blown in and supplied from a lower position of the center of the vulcanizing chamber toward an upper region of the vulcanizing chamber. The method and apparatus prevent a large temperature difference within the elastomer product and provide uniform vulcanizing product uniformity, shortening of the vulcanizing time, improvement of productivity, and reduction of energy loss.
