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.

Method for producing a composite fabric material and drive belt covered with composite fabric material

A belt comprises at least a belt body made of a polymer material having elastic properties, the belt including a cover layer as a belt backing, a substructure having a force-transmission zone, and a tension member in a ribbed design embedded in the belt body. The tension member is prepared with a cross-linked polyurethane in such a way that the polyurethane fills at least part of the tension member cavities. The polyurethane filling material enters into a mechanical connection to the tension member on the one hand and an adhesive connection to the belt body on the other hand. The polyurethane filling material has a Shore A hardness that is 0.5 to 10 times harder than the Shore A hardness of the belt body. The belt body is preferably likewise made of cross-linked polyurethane, in particular using a carbon tension member.
