SATISFIED PROBLEM 1. A film layer for a multicolor printing press paper guide roller, wherein the paper guide roller has a cylindrical base body having at least one paper holding device arranged on the base body and at least one Detachable film layer, characterized in that the film layer (5, 6) has the following layer structure: a layer of flexible substrate (12) whose bottom surface is assigned to the substrate of the paper guide roller (3) , - A layer (13) is reliably adherently disposed on the top surface of the substrate (12), the coating being made of a hard metal material, such as molybdenum, or a refractory material, which constitutes a slidable surface reaction layer. Corrosion-resistant and wear-resistant metals, such as NiCr-made metal alloys such as NiCr or variants thereof, a protective layer (14) which is reliably adhered to the top surface of the coating (13), The protective layer is made of a polyorganosiloxane or acrylate group, preferably a fluorinated variant, or a fluoropolymer family.

【Abstract】 A layer of paper guide rollers for processing equipment, especially printing presses or painting machines. The object of the present invention is to achieve a film layer that avoids the above-mentioned drawbacks, in particular having a surface with improved color separation properties and significantly reduced wear. This object is achieved by a film layer 5, 6 having the following layer structure: a layer of flexible substrate 12, the bottom surface of which is assigned to the substrate of the paper guide roller 3, a layer of which is adhesively attached to the substrate. 12 A coating 13 made of molybdenum or tungsten carbide/cobalt on the top surface, a protective layer 14 made of a polyorganosiloxane group that is reliably adhered on the top surface of the coating 13 , In addition, the film layers 5, 6 have a surface contour that faces the printed material and the surface contour consists of a cone 18 with rounded contour peaks 16.
