ABSTRACT:
A method of producing an endless belt includes the steps of: securing axial fibers relative to a mandrel, the axial fibers being spaced apart from one another at desired intervals and extending substantially parallel to a longitudinal axis of the mandrel; applying a polymeric base layer to the mandrel in a thickness sufficient to embed the axial fibers; wrapping circumferential fibers onto the polymeric base layer with sufficient tension to partially embed the circumferential fibers in the polymeric base layer; applying a polymeric top stock layer over the polymeric base layer and circumferential fibers; and curing the base layer and the top stock layer. This method can improve productivity and performance of endless belts, particularly if the wrapping and latter applying steps closely follow the first applying step.
