Abstract

The equipment consists of a rotating cover located in bearings at its ends and a fixed inner part on which an inner press roller is fitted. An external press roller has an inlet and outlet for heat transport medium, which can be liq. or gas-form. - The heat transport medium can be introduced through the cover of the inner press roller or directly to the space between the inner part and the cover from which space the medium outlet runs. Several stations can be positioned around the periphery of the rotating cover for redn. of material thickness. - In an alternative version, the internal pressure in a heat exchanger roller is transmitted to the pressure cylinders, thus producing pressure on an external press roller.
