Gas wiping apparatus

A gas wiping apparatus comprising:na chamber to which a high pressure gas is supplied, the chamber defining a multistage uniform pressure space;a lip support unit associated with a front of the chamber to allow the high pressure gas to flow therethrough, the lip support unit supporting the apparatus against load; andupper and lower lips associated with a front of the lip support unit to cooperatively define an outlet,wherein the chamber comprises a baffle wall hermetically disposed therein in a horizontal direction extending from the lip support unit to a rear wall of the chamber and provided with passage holes for ejecting the high pressure gas uniformly to form first and second uniform pressure spaces in the chamber.
