Steam-heated roller with cooling system

Image Number 4 for United States Patent #6185836.

A roller or roll heated by a gaseous heat carrier medium, preferably steam, having axially parallel peripheral passages for use in the pressing or smoothing station of paper making machines is connected to a device for the feeding and draining of the heat carrier medium so that for cooling the heated roller a cooling means is switched into the heating/cooling circuit and the direction of flow of the heat carrier medium may be reversed. Further aspects in accordance with the invention permit regulated cooling of the roller by blending heat carrier condensate into the return flow of heat carrier, by switching over between operation with a gaseous heat carrier and operation with a condensed heat carrier, as well as application of the invention in rollers having roller drive arranged on one flanged trunnion.
