Edge coating applicator nozzle

Abstract

An applicator nozzle adapted to apply a liquid coating to the shaped edge portions of work pieces. The nozzle is particularly adapted for applying a finish coat of paint to the beveled and adjacent nonparallel planar surfaces of the edges of fiberboard. The nozzle comprises a body member having a nose portion shaped to conform to the main configuration of the board edge to be coated. The front face of the nose portion has an open-end reservoir and a slot extending upwardly therefrom. A passageway extends from the reservoir through the length of the nozzle. Paint is fed through the passageway to the reservoir. During the application of paint to the edge portion of a board being conveyed past the nozzle, the beveled edge passes through a stream of paint issuing from the reservoir and partially seals it off, thus causing the paint in the reservoir to pressurize and be forced into any voids in the board's edge surface. The paint is simultaneously forced upwardly through the slot extending from the reservoir and is applied to the lower surface of the tongue and a small vertical edge portion of the board which extends from the beveled edge to the tongue's lower surface.
