Apparatus for coating edges of plank materials such as particle board plywood and-or platen board
Abstract
Abstract Edges of materials such as plywood and particle boards are coated and consequently sealed, producing an attractive edge appearance enhancing the utilization of such boards for shelving, etc. The apparatus and method used, continuously feeds a finishing substance having plastic properties into full contact with the edge of a board which is relatively moving by a pressurized emitting source of the plastic coating substance. This plastic emitting source structure confines the flow of plastic under pressure on board edges by utilizing a nozzle exit structure which has angular or beveled corners to receive the respective corners of particle or plywood board edges, etc., to thereby establish a uniform layer of coating across the width of the board edges without any plastic coating escaping to coat either the top or bottom surfaces of the boards.
