A device for the continuous profiles extruded forms of mixtures of rubber.

摘要

Apparatus for continuously vulcanizing rubber extrusions comprises a vat with electric heating elements for heating a vulcanizing liquid and a temperature control circuit. The invention solves the problem of positioning the heating elements, of their easy replacement and the optimal control of heating regimes. The vat has a trapezoidal cross-section, and the heating elements are formed as draw-out heating blocks placed under the vat bottom. The temperature control circuit is designed so that groups of the heating blocks can be connected in an arbitrary sequence either in delta, star or series to a source of three-phase current with the aid of three contactors.
