PURPOSE: An air knife nozzle for plating is provided to form a plated layer of high quality by making uniform the amount sprayed with the pressure sprayed on a body to be plated via a nozzle. CONSTITUTION: A guide roller(12) installed in a plating solution tub(10) impregnates a steel plate(14) wound on a bobbin(11) in a plating solution while the iron plate is unwound and winding-guided. The iron plate is passed between tension rollers(13,13') and left and right air knife nozzles(1) installed on the upper part of the plating solution tub and connected to a completed product winding bobbing. When steel material is moved by a driving part, the plating solution is spread in a certain thickness by forming a plated layer of uniform thickness by dispersing the plating solution on the plane surface by the pressure of the air sprayed from an air knife nozzle installed near the both faces of an irregular plating part(15) of the steel plate.
