Abstract
A method for casting cog-type power transmission belts from flowable elastomeric materials including the steps of forming a mold cavity defined by a mold mandrel and an outer mold shell, one of which has a plurality of axially disposed notches; wrapping preferably an extensible fabric about the surface of the notched mold portion; placing preferably fibrous loading members on the extensible fabric and superimposed over the axial notches; forcing the fibrous loading members and extensible fabric into the bottom contour of the notches; and introducing a substantial liquid elastomeric material into the mold cavity and polymerizing the elastomeric form in the mold to produce a sleeve containing one or more unitary endless cog-type belts.
