Abstract

PURPOSE:To prevent the flutter of the sheet to be treated on purpose to make possible the wiping work to be stably carried out, in the gas wiping method for making proper the thickness of the coating material, in the molten metal immersion plating, the metallic painting, etc., by installing the gas cushion portion at the upper position of the wiping nozzle. CONSTITUTION:The gas for blowing is introduced into the pressure accumulating chamber 9 installed in the main body 8 of gas wiping apparatus, and is blown off from the gas blowing hole 10 against the surface of sheet to be treated, the surface of sheet to be plated for instance, and then, is discharged downward passing through the gap between the plating surface and the wiping bar 12. Hereupon, the wiping portion displaces the molten plating metal 5' bulging from the plating bath surface depending on the travel of the plated sheet; hereby, the quantity of adhering metal is made the aimed value. In the meantime, a part of gas, flowing upward from the wiping portion, passes the gas-cushion portion 11 sectioned by multistage throttle portion 15, gradually reduces the pressure, and is discharged into the atmospheric air.
