Abstract

A method for producing a sheet-like composite fabric material, in particular a rubberized fabric or a fabric provided with a polymer preparation, for covering drive belts, the composite fabric material comprising a textile integrated in a matrix of elastomeric material, preferably at least one fabric layer integrated in a rubber matrix, the textile or the fabric layer and the elastomeric material being introduced into a gap between a band and a cylindrical molding wheel and molded to form a composite material between the band and the molding wheel at a temperature below the vulcanization temperature, the band looping around the molding wheel at a looping angle under pressure. Likewise disclosed is a drive belt with a covering of composite material produced according to the invention.
