  • Patent number: 4106613
    Abstract: A conveyor belt is disclosed of the type adapted to be supported and driven by a pair of wire ropes at or adjacent its edges. The belt comprises a body of rubber reinforced by at least two sheets of fabric embedded therein. Each sheet of fabric includes transverse filaments arranged in two planes and intimately bonded to the rubber. The transverse filaments are of specified size and elasticity. The combination of these physical characteristics of the filaments and their location in the rubber body result in the transverse filaments and the rubber acting together in the manner of an I-beam in resisting transverse loads, both compressive and tensile forces produced by transverse bending being carried principally by the filaments while shear forces are principally taken by the rubber.
