Apparatus for applying a coating, particularly for coating and advancing a substrate within a longitudinal passage having a plurality of transversely arrayed gaseous medium supply channels and a plurality of vacuum discharge channels intersecting the passage. A plurality of transversely arrayed coating medium supply channels intersect a processing side of the passage adjacent the vacuum discharge channels. Also, a restriction gap is defined in the passage intermediate the coating material supply channels and the vacuum discharge channels so as to insure filling of a first coating passage with coating material.
