ABSTRACT:
An endless power transmission belt body and a banded belt employing a plurality of such bodies are provided wherein each belt body comprises a tension section, a compression section, a continuous longitudinally extending load-carrying cord disposed between the sections and defined by a plurality of helically wound turns, and a platform on at least one side of the load-carrying cord with the platform having a fabric base layer and an elastomeric cord-engaging layer. The fabric base layer supports the plurality of turns in precise rectilinear alignment at any cross section along the belt body providing substantially equal load distribution in the turns promoting longer belt life and enabling winding of the cord at a comparatively large helix angle.
