Method for applying a coating on a substrate

Abstract

Method for applying a coating upon a substrate comprising: a. flowing gaseous medium longitudinally within confined passageway via a series of gaseous medium supply channels and vacuum discharge channels intersecting said passageway; b. introducing the substrate into an end of said passageway, so as to be supported and advanced, while being cushioned, by said flowing gaseous medium; while c. injecting a pressurized coating medium into said passageway via a series of branched medium supply channels intersecting said passageway adjacent said gaseous medium supply channels and gaseous medium discharge channels, so as to fill locally the longitudinal passageway; while d. restricting flowing of coating medium within said passageway by reducing the height of said passageway.
