Abstract
A calender roll, which was already in use and has a metallic core with engaged textile material sheets, can be worked for a new use. In the surface of the sheets are cut grooves, to which is subsequently applied a layer structure of synthetic resin-impregnated fibrous material forming a certain thickness over each point of the roll. Onto said layer can be applied a functional covering, for example of rubber.
