ABSTRACT:
A method of making a notched variable speed belt or a notched V-belt by placing the layers of the belt around a smooth cylindrical mold, placing an endless elastomeric sleeve having ribs on its inner surface, around the mold and layers thereon and applying heat and pressure to urge the sleeve against the belt layers to form a cured belt slab with molded grooves therein. The cured belt slab may then be cut into individual notched V-belts or variable speed belts of high quality.
