Abstract
An apparatus for applying a coating liquid to a web moving continuously along a path has a main frame forming an open space and a main backing roller journaled on the main frame and around which the web passes. A second frame in the space is independent of the main frame and displaceable relative thereto from a position in the space juxtaposed with the backing roller. An applicator unit on the second frame applies an excess of the coating liquid to the web and a dosing unit downstream along the path from the applicator unit strips from the web excess coating liquid and leaves on the web a coating of the liquid of a predetermined thickness.
