ABSTRACT:
A method of making endless power transmission belts each having at least a toothed outside surface is provided by building a belt sleeve on a drum and providing a reusable tubular polymeric curing jacket having a toothed inside surface around the sleeve with the teeth thereof adjacent the sleeve and curing the sleeve with the jacket therearound while subjecting the jacket to pressure such that the toothed inside surface of the jacket defines corresponding outside teeth on the sleeve; and, upon cooling the jacket and sleeve such jacket is readily removed for reuse thereby substantially reducing the cost of providing a toothed outside surface on a belt sleeve and belts defined therefrom.
