摘要： PROBLEM TO BE SOLVED: To suppress overcoating at edges of a steel sheet while suppressing the noise and vibration during gas wiping. SOLUTION: A main part 10 of a gas wiping nozzle 3 is formed with a slit-like gas blow-off port 11 long in the transverse direction H of the steel sheet H, a gas introduced port, and a gas flow chamber 13 for communicating the gas introduced from the gas introduced port with the gas blow-off port 11. Shielding belts 30 which shut off the flow of the gas in the gas flow chamber 13 are arranged on both sides of the gas flow chamber 13 in the longitudinal direction. The shielding belts 30 are freely advanceable and retractable from the end toward the central part of the gas flow chamber 13 and can shut off the flow of the gas flow chamber 13 from the end toward the moving destination of the gas flow chamber 13. As a result, the gas blown off from both sides of the gas wiping nozzle 3 can be shut off and be sprayed only to the area on the side inner than both ends of the steel sheet H.

摘要： PROBLEM TO BE SOLVED: To smooth a surface treating agent adhered to the whole surface of a metal strip easily and uniformly and to improve productivity by allowing a fine surface treating agent to adhere to the metal strip, and ejecting a gas jet from at least a pair of slit-shaped gas ejecting nozzles. SOLUTION: When a surface treating agent A is applied by passing a metal strip 1 upward and continuously through a vertical pass line, in the first section, a fine surface treating agent A is applied from an electrostatic applicator (or spray applicator) 2 on both sides of the strip 1. Next, in the second section, when passed through a part of a slit-shaped gas ejecting nozzle 3, the agent A adhered to the whole surface of the strip 1 by a gas jet ejected from the nozzle 3 is smoothed uniformly. The nozzle 3 is constituted so that its angle can be changed as required, and the ejection angle is adjusted corresponding to the viscosity, surface tension, and others of the agent.
