Abstract

The invention relates to a device for blowing off excessive coating material, especially fluid zinc or aluminium, in the coating of metal bands. The device comprises a blowing off jet impinged on compressed air, of which the jet bodies 3,4 are fixed at a base body 1. The jet lips 3,4 adjustable against each other form a jet slit 10 extending in transverse direction of the metal band. For optimizing an adaption of the slit thickness respectively the pressure of the blowing off medium along the band width it is provided to build the blowing off jet as a jet row, providing in transverse direction of the band at least two partial jets 2 to impinge seperately on a blowing off medium, especially compressed air, sealed against each other, of which the respective partial slits are adjacent forming a continuous jet slit (10).
