Patent ID: 7041021

Claim:
A toothed power transmission belt having a tensile-loaded body portion composed of an elastomeric material, a plurality of spaced teeth bonded with and disposed along at least the inner periphery of the body portion, a fabric cover element having voids therein and positioned intimately along at least a portion of the outer surface of said body portion's inner periphery, made according to the method characterized in that: a) said fabric cover element is immersed in a first treatment composition containing at least one cross-linkable component, to effect a pick-up rate of from about 1% to about 25%, based on the dry fabric weight to fill only a portion of said voids; b) a wear-resistant composite comprising at least one binder constituent and at least one friction-modifying constituent is applied to a first surface of said fabric cover element forming the power transmitting surface of said belt, to fill a portion of said voids at said first surface; c) the fabric cover element is applied to the outer surface of said belt; and d) the belt is vulcanized; and further characterized in that said wear-resistant composite comprising at least one friction-modifying constituent penetrates at least a portion of the total thickness of the fabric cover element, and is substantially separated from the elastomeric belt body by a boundary, and that the binder is abrasion-resistart.
