ABSTRACT OF THE DISCLOSURE A trapezoidal endless power transmission belt structure is pro- vided which is made primarily of elastomeric material (e.g. rubber) and has a pair of oppositely arranged surfaces disposed in spaced relation to define an outside and inside surface of the belt structure and has a load- carrying section arranged midway between the inside and outside surfaces. The belt structure has a tension section and a compression section which are of similar construction and each is comprised of a plurality of layers including means providing transverse rigidity adjoining the load-carrying section, e.g., a fiber-loaded layer disposed adjacent the load-carrying section and a fabric layer disposed remote from the load-carrying section. Each of these fiber-loaded layers have a plurality of randomly arranged fibers therein. The fabric layers and fiber-loaded layers cooperate to assure that the belt structure has longitudinal flexibility yet has transverse rigidity sufficient to enable the belt structure to be operated in associated sheaves substantially free of shear planes parallel to the load-carrying section.
