ABSTRACT:
An application device capable of very rapidly applying a liquid in the form of a thin film to a continuously moving flexible carrier in such a manner as to avoid corrosion and wear to the surface of the doctor edge portion of the application device to thus avoid the formation of streaks on the surface of the applied liquid. A clearance between the surface of the carrier and the surface of the doctor edge portion is made larger at the downstream end of the surface of the doctor edge portion than at the upstream part thereof. For this purpose, a support roller is provided near the downstream end of the surface of the doctor edge portion so that the clearance between the surface of the doctor edge portion and the surface of the carrier can be appropriately controlled along substantially the entire width of the doctor edge portion by adjustably displacing the roller. Application is performed while the clearance between the surface of the carrier and the doctor edge portion is set larger at the downstream end of the surface of the doctor edge portion than at the upstream part of the surface thereof.
