ABSTRACT:
Heating or cooling roll having a roll jacket with axially running peripheral borings at the roll ends, where the borings are connected via a fixed ring shaped part which is sealed against the roll jacket, to each other and/or with the feed-in or feed-out lines of the heat carrying fluid which are mounted outside of the roll. With this simply constructed device, the feeding in and out of the heat carrying fluid is made possible, even for rolls which have a roll jacket which is shiftable in the pressure plane.
