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.

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.

Abstract: A resilient coupling with a limited range of radial movement is provided, more especially for a pulled wheel attachment, of the type comprising two cylindrical sleeves one of which surrounds the other and between which is adhered a block of a resilient material. In said block of resilient material (3') there is formed laterally at least one groove (5), and preferably two grooves, one at each end of the block.
