Patent ID: 7211297

Claim:
A method of applying coating liquid onto a surface of a web moving in a given direction, comprising: introducing coating liquid under pressure onto a concave curved surface that curves toward the web surface and has a terminal portion spaced from and extending toward the web surface in the direction of movement of and at an acute angle to the web surface; flowing the coating liquid along the concave curved surface to form a sheet of coating liquid on the curved surface, to subject the sheet of coating liquid to centrifugal force to concentrate coating liquid toward one side of the coating liquid sheet that is toward the concave curved surface, and to redirect the coating liquid sheet for flow in the direction of movement of the web surface; directing the coating liquid sheet from the terminal portion toward and in the direction of movement of and at an acute angle relative to the web surface to contact the web surface with the one side of the coating liquid sheet that was toward the curved surface to apply onto the web surface a layer of coating liquid; and doctoring the coating liquid on the web surface.
