ABSTRACT:
The invention relates to a frictionally engaged driving belt having a base body (2) and a cover layer (1) that consists of rubber or a rubber-like synthetic material which is provided with a tractive support layer (3) that is embedded into the rubber or the rubber-like synthetic material. The aim of the invention is to prevent or reduce the generation of noise in drives of the belts. Only the surface or a portion of the surface, preferably the motion-transferring part of the surface, pertaining to the driving belt is provided with a flocking material consisting of short aramide fibers (5). A portion of said aramide fibers (5) is integrated into the surface only with a partial length of each individual fiber.
