ABSTRACT:
Apparatus for vulcanizing an elastomeric product includes separate passageways for supplying a heating medium to a lower portion of the vulcanizing chamber and an inert gas pressurizing medium to the upper portion of the chamber. The mixing of the fluids minimizes the temperature difference in the inner space of the product and ensures a uniform vulcanization.
