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.Field of SearchHeater and cooler serially arrangedInto a liquid bath Filaments UTILIZING SPECIAL INERT GASEOUS ATMOSPHERE OR FLUSHING MOLD WITH INERT LIQUID To complete vulcanization or polymerization Means directing product through tubular conduit within bath or shower means INCLUDING MEANS ADVANCING CONTINUOUS LENGTH WORK THROUGH DOWNSTREAM LIQUID BATH OR SHOWER MEANS Extrusion shaping means Means to feed or support plural preforms to or at extrusion means Including product handling means Including both heating and cooling means Rod or tubular preform SHAPING MEANS AND SUBSEQUENT PRODUCT TREATMENT MEANS MEANS TREATING SHAPED WORK LIQUID POOL SEALING RELATIVELY MOVABLE CHAMBER WALLS | |
