Patent ID: 8100817

Claim:
A cylindrical press roller with a roller jacket having a midpoint and outer axial ends, said roller jacket made of plastic material for the treatment of a fibrous material web in a machine for the production and/or finishing thereof, said roller jacket having a given outer smooth pressure application cylindrical surface at the midpoint of said roller jacket, the outer diameter of said roller jacket at the axial outer ends being less than the outer diameter at the midpoint of said roller jacket, wherein the outer cylindrical surface of the roller jacket possesses at least partially at least one of a temperature-stable protective layer and a cover each having an axial length, wherein the outer cylindrical surface is enveloped by at least one of a temperature-stable protective layer and a cover only in the area of at least one of the outer axial ends of the roller jacket and wherein the outer diameter of said at least one of a temperature-stable protective layer and a cover is not substantially greater than the outer diameter of the cylindrical surface of the midpoint of said roller jacket and said one of a temperature-stable protective layer and a cover contacts the outer cylindrical surface the entire axial length of said one of a temperature-stable protective layer and a cover.
