Abstract
An edge dam assembly for an applicator for applying a film of coating material on a moving web of paper carried through an application zone, is characterized by a seal element at each side end of the zone. To prevent leakage of coating liquid past the seal element, air is introduced through the element and into the side end of the zone adjacent to the element. The air forms an air barrier pocket at the side end of the zone, which is void of coating liquid, whereby coating liquid is maintained in the zone inwardly of the seal elements.
