Abstract
A roll cover and a roll in particular for use in a machine line for the production or processing of a fibrous web is provided, wherein the roll cover includes a radial outer functional layer which provides the surface of the roll cover in contact with the web, and wherein the functional layer has structural elements, in particular in the form of grooves and/or bores, wherein the functional layer is constructed of an elastomer material with a Poisson number greater than 0.4, between 0.45 and 0.5.
Claims14
A roll cover for a roll, the roll cover comprising:
- a surface configured for being in contact with a web of fibrous material, the surface being formed by a radial outer functional layer, the radial outer functional layer including a plurality of structural elements and being composed of an elastomer material that has a Poisson's ratio greater than 0.4.
A roll for a machine line for producing or processing a web of fibrous material, the roll comprising:
- a roll core which is substantially cylindrical;
- and
- a roll cover applied to the roll core, wherein the roll cover includes a surface configured for being in contact with the web of fibrous material, the surface being formed by a radial outer functional layer, the radial outer functional layer including a plurality of structural elements and being composed of an elastomer material that has a Poisson's ratio greater than 0.4.
