A fluid delivery apparatus (10) and method is provided wherein either liquid or gaseous fluid is provided from fluid dispensers (17, 18), via nozzle plates (40) associated therewith, on each side of a path of travel of articles (11) being treated by the fluid, and wherein nozzle openings in nozzle plates cooperate with transverse groove(s) (67) to provide a screen flow of fluid extending transversely of the path of travel (22) of articles, and directed toward the articles. In the case of the fluid being a liquid, the nozzle openings provide cylindrical filament-like columns of liquid which are rendered by the associated grooves into flat, transversely disposed screen spray of liquid. In the case of the fluid being a gas, the nozzle openings and transverse grooves cooperate to deliver the gas in transversely spaced apart, transverse, planar zones of gas directed toward the path of article travel.
