FILM APPLICATOR WITH ENTRAINED AIR REMOVAL AND SURFACE CONTROL |
摘要 |
A uniform film of coating is delivered onto a substrate such as paper, felts and blankets by a film applicator (20; 100; 120; 142) which has a static converging wedge (32; 88; 108; 128; 150), an adjustable converging wedge (33), and an extraction channel (45; 92, 112; 132; 154) 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.
