Apparatus for applying a lacquer or similar protective coating to one surface of a metal sheet is constructed with upper and lower sub-assemblies. The upper sub-assembly includes an applicator roll, a lacquer supply means, and metering rollers for applying a controlled layer of lacquer to the applicator roll. The lower sub-assembly includes an impression roll and a clean-up system therefor, with the elements of the clean-up system being readily movable to accessible positions by means of slide and/or pivot connections. A register conveyor, which receives metal sheets from an initial conveyor, delivers these sheets to a suction belt that feeds the metal sheets to the nip between the applicator and impression rolls in timed relation therewith. The register conveyor is adjustable while running without disturbing coordination thereof with the initial conveyor. Operation of air operated side guide means is controlled by a cam operated switch mounted on the movable carrier to which the register conveyor is mounted so that adjustment of the register conveyor does not require readjustment of side guide operation.
