ABSTRACT:
An endless power transmission belt construction having power transmitting contact faces and method of making the same are provided, the belt construction comprising an axial tensioning unit, a plurality of lateral stiffening units carried by the tensioning unit, and friction material carried by at least one of the tensioning unit and stiffening units, the tensioning unit and the stiffening units being formed of polymeric material that provides an axial and lateral stiffness in excess of that normally provided by polymeric friction material that normally forms the main body of a belt construction that is reinforced with such a tensioning unit and stiffening units. The stiffening means and the tensioning means are formed of the same material and comprise a one-piece construction. The friction material is located only at the contact faces of the belt construction and thereby defines only the contact faces of the belt construction while the tensioning and stiffening units define all other exposed areas of the belt construction.
