ABSTRACT OF THE DISCLOSURE A multi-ribbed endless power transmission belt is provided which is made primarily of elastomeric material for use with multi grooved pulleys in a serpentine drive system. The belt comprises a first portion having one face defining the bottom surface of the belt and comprising a plurality of laterally spaced power-transmitting ribs, each of the ribs having a cross-sectional configuration adapted to conform to a groove of the pulley, and a groove between each adjacent rib penetrating from the bottom surface and terminating at the opposite top surface of the first portion; a second portion bonded to the top surface of the first portion; and a third portion having one face defining the top surface of the belt and comprising a plurality of laterally spaced power-transmitting ribs, each of the ribs having a cross-sectional configuration adapted to conform to a groove of the pulley, and a groove between each adjacent rib penetrating from the top surface of the third portion and terminating at the opposite bottom surface of the third portion; the bottom surface of the third portion being bonded to the second portion, and the third portion being symmetrical with the first portion about the second portion wherein the grooves between the adjacent ribs in the first portion and the second portion are configured to provide relief areas between the ribs and adjacent second portion to allow debris to work through the second portion and thereby become discharged. This belt is a double multiple wedge belt which is particularly suitable for applications, e.g. rock crushing, in which foreign matter may pass through the band which ties together the multiple belt elements.
