PROBLEM TO BE SOLVED: To provide a gas-wiping device capable of preventing generation of defective surface quality caused by expansion of splash generated during the high-speed plate passing to an upper surface side of a wiping nozzle and re-deposition thereof, preventing generation of any flaw caused by C-warping and the contact with a portion of poor plate shape of a weld part due to the non-contact, reducing the cost for changing parts by the wear, and performing the operation as a regular wiping device at a low-speed plate passing.;SOLUTION: The gas-wiping device has a pressure application chamber for housing a metallic strip immediately above a wiping nozzle outlet side. The pressure application chamber has a gas introducing pipe for applying the static pressure. An opening part is formed on an upper part of the pressure application chamber as an outlet of the metallic strip. Any part other than the opening part and the wiping nozzle part is closed.;COPYRIGHT: (C)2008,JPO&INPIT
