ABSTRACT:
An apparatus for continuous curing (vulcanization) of elongated products, such as cables comprising a conductor surrounded by a mantle of a crosslinkable material. The cable is passed longitudinally through a curing tube in which the cable is first subjected to heating in a heating zone for heating the cable to curing temperature and subsequently subjected to cooling. The heating of the cable in the heating zone is carried out by means of heat radiation in a pressurized gas atmosphere and the cooling of the cable in the cooling zone is carried out in the presence of a gas under pressure so that heat is transferred from the heated cable in the cooling zone partially by radiation to the cooled wall of the tube and partly by convection to said cooled gas.
