Abstract
The metallic strip is displaced in a non-oxidizing gaseous atmosphere above and at a small distance from the surface of the coating bath and in contact with a coating cylinder driven to rotate in a direction opposite the direction of travel of the strip, so as to transfer onto the lower surface of the strip a thick layer of the coating material. Apparatus is arranged downstream of the coating cylinder to produce a jet of non-oxidizing gas directed to extend over the entire width of the strip, so as to adjust to a predetermined value the thickness of the coating layer.
