ABSTRACT:
A plant for carrying out a process of continuous vulcanization of articles of elastomeric material comprises a vulcanization apparatus comprising a circuit for a heat exchange liquid. The circuit comprises a vulcanization chamber arranged to receive the heat exchange liquid, means for heating the liquid to a predetermined temperature, and means for generating a predetermined pressure in the circuit. The circuit has at least one inlet and one outlet to allow passage of articles through the chamber, seals disposed at the inlet and outlet to ensure tightness of the passage of articles through the inlet and outlet and means to prevent contact between the seals and the high temperature liquid contained under pressure within the circuit.
