A fluid delivery apparatus and method is provided wherein either liquid or gaseous fluid is provided from fluid dispenser manifolds (35), via nozzle plates (40) associated therewith, on each side of a path of travel (22) of articles (11) being treated by the fluid, and wherein nozzle openings (41, 42, 43) in nozzle plates (40) cooperate with transverse groove(s) (67) to provide a screen flow of fluid extending transversely of the path of travel (22) of articles (11), and directed toward the articles (11). In the case of the fluid being a liquid, the nozzle openings (41, 42, 43) provide cylindrical filamentlike columns of liquid which are rendered by the associated grooves (67) into a generally flat, transversely disposed screen spray of liquid. In the case of the fluid being a gas, the nozzle openings (41, 42, 43) and transverse grooves (67) cooperate to deliver the gas in transversely spaced-apart, transverse, planar zones of gas directed toward the path of article travel (22). In the case of liquid flow, the openings (41, 42, 43) are generally cylindrical, and in the case of gas flow, the openings (41, 42, 43) are generally spaced-apart slotted holes. In the cases of both liquid and gas fluids, one of the grooves (67) and/or nozzles (41, 42, 43) are directed upstream relative to the path of article flow (22). Various adjustments are provided for adjusting the positions of the nozzle plates (40) relative to the path of flow.
