Abstract
The invention concerns a method of manufacturing a ribbed vulcanized transmission belt having an elastomer cushion layer and an elastomer compression layer in which reinforcing fibers are embedded. The method comprises the following steps: a) forming a blank having at least the cushion layer and the compression layer; b) molding said blank under pressure in a mold provided with an imprint of the ribs; c) vulcanizing said blank; d) machining off surplus material so as to uncover protruding ends of the fibers. In the belt of the invention, in the vicinity of the surfaces of the ribs, the mean direction of the reinforcing fibers is substantially tangential to the surfaces of the ribs, and, in at least one region of each of said ribs, said fibers have protruding ends.
