ABSTRACT:
An improved drive belting comprises a woven tape constraining element embedded in a polyurethane body element. The warp threads of the woven tape constraining element have a higher modulus of elasticity than the polyurethane body element, are resistant to heat shrinkage and extend substantially through the length of the polyurethane body element to resist extension of the polyurethane body element. At least the warp threads of the woven tape are preferably composed of rayon, although the weft threads may be nylon. The polyurethane has good frictional properties and is extremely wear resistant making it particularly suitable for driving belts.
