ABSTRACT:
A method of making arched polymeric V-belts is provided which utilizes a cylindrical polymeric forming member which has radially inwardly facing annular concave polymeric forming surfaces and wherein an uncured belt sleeve is placed with its normal outside surface adjacent the polymeric forming surfaces and compressed thereagainst during curing thereof and the compressing action is achieved by engaging the inside surface of the belt sleeve and urging the belt sleeve radially outwardly against the polymeric forming member and its forming surfaces while transmitting the same pressure against each unit area of such inside surface to thereby define annular arched belt portions in the sleeve which are then cut from such sleeve to define arched belts each having a convex surface and an opposite concave surface which are defined with great precision and with all arched belts cut from the cured belt sleeve being substantially identical.
