Abstract
Apparatus for applying a coating liquid to a moving web of paper carried through an application zone is characterized by a system at each side end of the zone for recirculating coating liquid thereat. In use of such an applicator coating liquid at the side ends of the zone tends to stagnate, and the recirculating system eliminates coating buildup in the side ends.
