V-BELT Abstract of the Disclosure A power transmission belt has an elastomeric body which is frusto-triangularly shaped in cross-section. Such power trans- mission belts are commonly referred to as V-shaped belts. The belt provided by the invention has a plurality of laterally spaced cords which are parallel to each other and are arranged longitu- dinally throughout the length of the belt. At least those portions of the sides or flanks of the belt which bear against the walls of grooves of a pulley wheel when the belt is rotated are covered with an elastomeric composition having cut lengths of fibrous material embedded therein and disposed so the longitudinal axes of the fibers are substantially perpendicular to the longitudinal plane of symmetry of the belt. The fibers may be impregnated with an organic polyisocyanate solution.
