A gas wiping apparatus and method can reliably prevent edge overcoat and splash, by using face gas wiping nozzles extending widthwise of a strip material (9), a pair of baffle plates (6) spaced from an edge of the strip material, and an edge wiping nozzle (7) disposed between baffle plates at its inner edge and adjacent the strip material edge, all with critical spacings (L and C) relative to each other. The apparatus and method are of particular use when plating steel strip with zinc, alumium or alloys thereof. <IMAGE> |
