Abstract of the Disclosure A fabric to have a coating of controlled thickness applied to its upper surface moves between a supporting roll and a supporting plate. The lower surface of the fabric contacts the supporting roll and supporting plate but is unsupported therebetween. Between the supporting roll and plate, the moving fabric is depressed by a blade extending across its width. Near to the blade and between this blade and the supporting plate, a coating is applied to the upper surface of the fabric. A gauging device adjacent to where the coating is applied controls the thickness of the coating. The distance between the blade which depresses the fabric and the supporting plate should be several orders of magnitude greater than the distance between this blade and the gauging device. Any variations in fabric thickness as the fabric passes over the supporting plate would cause corresponding variations in the coating thickness if the coating were being applied over this plate. Controlling the coating thickness at the gauging device reduces the coating thickness variations which would occur if the coating were applied over the supporting plate by the factor of the distance between the blade which depresses the fabric and the gauging device divided by the distance between this blade and the supporting plate.
