Abstract
A roll (1) for the press of a paper machine or the like, comprising a substantially rigid cylindrical shell body (2); a resilient layer (3) made of a resilient material such as rubber and positioned on the shell body; and a surface layer (4) positioned on the resilient layer. The resilient layer (3) is formed by fastening profiles (9) made of soft and resilient rubber to the surface of the shell body (2) in such a manner that substantially equally wide conduits (10) are defined between the profiles (9). The surface layer (4), in turn, is fastened to the profiles (9) on to the surface facing away from the shell body (2). In order to cool the resilient layer (3) of the roll (1), water is introduced into the conduits (10) between the profiles (9) through one connection conduit (8).
