ABSTRACT:
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, wherein the method comprises forming a blank having at least a cushion layer and a compression layer, molding the blank under pressure in a mold provided with an imprint of a plurality of ribs, vulcanizing the blank, and machining off surplus material to uncover protruding ends of the reinforcing fibers in at least one region of each rib. 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.
