Abstract:
The present invention relates to an apparatus for correcting warps such as gutter and curl in a metal strip. The apparatus comprises a small roll which is preceeded by rolls for correcting defects in the shape of the metal strip such as edge wave, full center and quarter buckle and said small roll is followed by at least one medium roll. The small and medium rolls are supported by a film of pressurized liquid and the rolls rotate freely in contact with the moving metal strip, which is bent under tension by said small and medium rolls. The gutter and curl defects are thus each completely eliminated independently of the other.
