Abstract: A plurality of individual power transmission belts are made in a simultaneous manner utilizing the method of this invention while making full use of standard injection molding equipment. The method employs an apparatus comprised of a lower structure and an upper structure suitably fastened together and having cooperating surface means which define a plurality of annular cavities with each cavity defining an associated belt. The cavities are supplied from a common sprue and the plurality of belts are formed by the simultaneous injection of elastomeric material into such cavities and then curing and cooling the material to define the transmission belts.
