ABSTRACT:
A slide-bead coating technique utilizes an inclined slide surface terminating at a coating lip. A continuous liquid layer is supplied to the slide surface from a supply source so as to form a liquid bridge between the coating lip and a substrate disposed adjacent the coating lip. The substrate is conveyed past the lip and continuously depletes liquid from the liquid bridge onto the substrate. The technique includes supplying an air flow that impinges upon an upper surface of the liquid layer opposite the slide surface between the liquid supply source and the coating lip.
