ABSTRACT:
A method for removing liquid from the surface of a plate-shaped material, for instance, as applied to removing surface treatment liquids from metal plates of photographic film. While the plate-shaped material is being conveyed, a larger part of the liquid is removed from its surface by a first liquid removing device having a solid scraping surface positioned adjacent the surface of the plate-shaped material. This first liquid removing device may be a scraper blade or a pair of rollers. Subsequently, liquid remaining on the surface of the plate-shaped material is removed by a second liquid removing device, specifically, an air knife. The air flow rate and air pressure used with the air knife are sufficiently low that there is no significant scattering of liquid from the surface of the plate-shaped material.
