Abstract
A cylinder or roller for paper, plastic or material webs is formed of a plastic material reinforced with fibers and is used for the purpose of transporting, deflecting or web guiding. Instead of a layer covering the casing and being applied with an electrolytic method or by a thermal spraying method, an abrasion-resistant layer of a synthetic resin and a filler of a powder of abrasion-resistant material is used.
Claims16
A cylinder or roller, comprising:
- a base body of fiber-reinforced plastic having an outer roller surface;
- and
- a wear-resistant layer at least partially covering and adhering to the outer roller surface in an undetachable manner;
- said wear-resistant layer being formed of a mixture of a synthetic resin and 20 to 70% by volume of a wear-resistant pulverized filler, relative to the total mixture in a hardened state.
