ABSTRACT:
A uniform film of coating is delivered onto a substrate at high speed by a film applicator, such as a coater apparatus for a papermaking machine, which has a static converging wedge, an adjustable converging wedge, and an extraction channel located between the two wedges. As a unit, the film applicator minimizes the hydrodynamic flow instabilities, as well as reduces flow variations associated with a nonuniform feed and a dynamic contact line. The film applicator also removes entrained air and excess coating from the application zone in order to improve the flow stability and machine runnability.
