Abstract: A belt (1), and a method of forming a belt (1), with at least one row of teeth (5) formed on at least one surface of the betling (1). To improve the tooth formation of the belting (1), and the abrasion of the belting (1), the outer surface of the teeth (4) are formed with the disclosed bi-directional stretch woven fabric (7). The warp (10) and weft (11) yarns are formed of a core yarn (12) about which is helically wrapped at least one yarn (13 or 14), forming a scaffold construction. The bi-directional stretch characteristics of the fabric (7) permit greater deformation of the fabric (7) while forming the belt teeth (5).

Abstract: An endless power transmission belt comprising a tension section, a cushion section and a load-carrying section disposed between the tension and the cushion sections, and at least one drive surface having fabric layer bonded to an outer surface of the belt is coated with a layer of polyvinylidene fluoride.

Abstract: An endless power transmission belt comprising (a) a tension section; (b) a cushion section; (c) a load-carrying section disposed between said tension section and cushion section; and (d) at least one drive surface having a fabric layer bonded to an outer surface of the belt, the improvement comprising a coating layer on said fabric layer of a composition containing a zinc salt unsaturated carboxylic acid ester grafted hydrogenated nitrile butadiene elastomer, a curing agent for said elastomer and from 5 to 60 phr of PTFE in the form of fibers, powder and mixtures thereof, dispersed throughout said composition.

Abstract: A high modulus composition based on a mixture of a hydrogenated acrylonitrile butadiene rubber which has been modified with either zinc methacrylate or a combination of zinc oxide and methacrylic acid and an unmodified hydrogenated acrylonitrile butadiene rubber for use in high load-bearing synchronous drive belts and belts made therewith.
