Abstract of the Disclosure A method of making toothed power transmission belting having pre- ferably an elastomer-free sprocket-engaging toothed surface is described. A temperature sensitive tackifier is applied to a toothed mold surface and the belt face cover is stitched to the tacky surface, and then preferably fur- ther immobilized by winding tensile cord circumferentially about the mold. Elastomeric material is introduced into the tooth and body portions of the belt and the belting is cured. The temperature is elevated at some point during the process, whereby the tackifier loses its adherence to the mold, permitting easy demolding of the product.
