Process and apparatus for removing impurities from surfaces contaminated with liquid

Abstract

In order to remove impurities, especially liquids (5) and/or particles (4) from surfaces of plate-shaped workpieces (2) contaminated or wetted with liquid (5), at least one wiping element (3) is provided which moves with respect to the surface (2a) the wiping element (3) to be cleaned and contacts this surface (2a). The wiping element (3) is cooled down so that the liquid (5) coming into contact with this wiping element (3) and bristles (8) preferably provided thereon assumes a higher viscosity or even solidifies and consequently remains adhered together with the particles (4) contained in the liquid (5) to the wiping element (3) or its bristles (8). This cleaning principle can be assisted and influenced by heating of the surface of workpiece (2) upstream of the wiping element or elements (3) in the feed direction.
