Abstract
Apparatus for applying a liquid coating to the surface of a sheet workpiece and adapted for operation on-line with the last unit of a lithographic sheet printing press. The apparatus comprises: (1) a textured metering roller in a mount which is linearly movably attached to a support platform fixed adjacent the press unit, and extending between the last press unit and a remote point. The support platform allows movement of the metering roller and the mount between a first position in which the mount is continuously adjustably biased against the last press unit, and a second position, away from the last press unit to allow use of the last press unit as a lithographic press. The platform comprising longitudinal supports arranged generally perpendicular to a vertical plane through the axis of said metering roller, and the metering roller mount is movably supported and guided along the supports. In the first position, the metering roller continuously delivers a smooth, uniform, metered amount of liquid material to the blanket roller of the printing press. The apparatus also includes a latch that allows the mount, with its attached metering roller, liquid coating supply, and metering roller rotation device, to be readily detached from and moved out of the way of the press unit, so that the press unit can be used as a lithographic press unit. A biasing latch and an adjustable stop allow the metering roller and mount to be readily and reliably returned, locked and biased in the first position.
