ABSTRACT:
An endless power transmission belt construction and method of making the same are provided, the belt construction having opposed side edges and having an inner surface defining a plurality of longitudinally disposed and alternately spaced apart projections and grooves for meshing with a ribbed surface of a rotatable pulley or the like and defining a plurality of transversely disposed and alternately spaced apart projections and grooves that respectively extend between and to the opposed side edges, the longitudinal spacings between the transverse grooves or/and the depths of the transverse grooves being staggered so as to tend to reduce noise during normal operation of the belt construction with the pulley or the like.
