ABSTRACT:
A method and apparatus for coating a moving web with a coating fluid. The coating die has at least one feed slot for supplying the coating fluid to the moving web and a front face demarked from the at least one feed slot by a die edge. A guide mechanism guides the moving web in a first direction past the coating die such that a coating bead is formed in a gap between the moving web and the die edge. The spraying system sprays a cleaning fluid on at least a portion of the front face of the slide coating die such that the coating bead forms a substantially linear static wetting line on the front face of the coating die.
