ABSTRACT:
A device for removing liquid from the surface of a moving strip (B), more particularly a rolled strip on a roll stand, by means of a gas, more particularly air, blown on to the moving strip (B), is characterized according to the invention in that disposed transversely of the direction (L) in which the strip runs is a slot nozzle (3) which is directed at the strip surface at an angle (.beta.) of 45.degree. to 90.degree. of its jet oppositely to the direction (L) in which the strip runs, the ratio between the distance (h) of the slot nozzle (3) from the moving strip (B) and the width (s) of the slot is in the range h/s=2 to h/s=10, so that the velocity of emergence of the gas jet blown by the slot nozzle (3) on to the strip (B) is in the range of 0.3<Mach<2, and a suctional removal gap (4) is disposed above the strip (B) at a distance of 5 to 25 nozzle distances (h) in the direction (L) in which the strip (B) runs upstream of the line of impingement of the gas jet emerging from the slot nozzle (3).
