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 the units, the tensioning unit and the stiffening units being formed of 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 friction material has a first portion thereof disposed on the units to define the contact faces thereof and has a remaining portion thereof disposed on the units to at least assist in securing the first portion to the units, the thickness of the first portion of the friction material being relatively thin and the thickness of the remaining portion being no thicker than the thickness of the first portion whereby a substantially large amount of the belt construction comprises the material of the units and a substantially small amount of the belt construction comprises the friction material.
