ABSTRACT:
An application roller to apply a treated liquid of low viscosity onto the surface of a film or sheet which moves at super high speed includes a radially inner axially extending tubular treated liquid distribution channel for distributing the treated liquid in axial and radial directions, with an outer tubular roller body having an outer surface with circumferentially extending adjacent tops and valleys. The valleys are formed with laterally extending substantially parallel surfaces so that the application roller is of substantially gear shape on its exterior surface and including a lining of an application material over the exterior surface which, at least, cover the tops. The construction also includes a conveyor channel for the treated liquid formed between the treated liquid distributing channel and the application material.
