PROBLEM TO BE SOLVED: To facilitate the maintenance of a spray nozzle by eliminating the generation of deposit A formed by the sticking of dust, paper powder, or the like, on the bottom face of the spray nozzle, which is caused by the generation of air entrainment, in curtain spray coating. SOLUTION: In a method for curtain fiber like spray coating, the generation of the air entrainment is obstructed and cut off by forming a 2nd pressurized air flows discharged from a 2nd pressurized air flow hole at a certain distance from the pressurized air flow in the front side and back side of the pressurized air flow and supplying the 2nd pressurized air flows K2 to the outside of a 1st pressurized air flow K1 to form an air curtain by the 2nd pressurized air flows in the front side and back side of curtain fiber like hot melt adhesive.
