ABSTRACT:
A screening chamber for filtering paper coatings is cleaned with the use of a plurality of water sprays. The water sprays are provided by nozzles located on spray bars positioned transversely across the width of the screening chamber. The nozzles are oriented to direct selected spray patterns tangentially against the screens, and against the interior surfaces of the screening chambers, to remove particulates, debris and other contaminates which collect on the screen during the filtering process.
