ABSTRACT:
An edge coating apparatus adapted to apply a liquid coating to the shaped edge portions of work pieces. The apparatus is particularly adapted for applying a finish coat of paint to the beveled and adjacent non-parallel planar surfaces of the edges of previously face-coated fiberboard. The apparatus comprises an endless belt mounted on and driven around four standard pulleys located 90.degree. apart in a horizontal plane. The applicator side of the belt is shaped to conform to the main configuration of the board edge to be coated. The other side of the belt acts as a drive. Paint is applied to the belt at a point prior to its arrival at the point of paint application. Resilient means is provided for biasing the belt into and maintaining contact with the work piece. Due to the configuration of the applicator side of the belt and the pressure maintained on the belt at the point of paint application, the paint is forced into any voids in the board's edge surface 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.
