Abstract

The invention relates to a take-off roll, spreader roll or equivalent roll of adjustable curvature for processing of a material in web form, the roll comprising a non- rotatable shaft 10 and a roll shell 20 rotatably supported thereon, which is supported on the shaft 10 by multiple bearings 30, 31, of which some are situated in the central area of the roll shell 20 and are thus in the area of the web material run. The invention also relates to a method for reducing temperature differences in such a roll. The roll shaft 10 is a hollow tube with a flow duct 40 running at the centre, through which a heat transfer medium is designed to be fed for cooling or heating of the shaft 10. <IMAGE>
