Abstract
A rolling mill for the treatment of sheet material comprises two work rolls (1, 2) which define a nip between which a web of material (3) is passed for rolling. The work rolls (1,2) are offset in a horizontal direction relatively to back-up rolls (4,5), so that the plane containing the axes (A,A) extends parallel to but offset relative to the plane containing the axes (B,B) of the back-up rolls (4,5). Supporting devices (9) are associated with the work rolls (1,2) and support the work rolls in the direction opposite to that in which they are offset from the back up rolls. The supporting devices (9) comprise hydrostatic supporting elements (19,20,21) which are arranged parallel to the longitudinal axis (A) of the work rolls (1,2) and comprise hydrostatic pressure pockets (29) which face towards the surfaces being supported in each case and can be individually controllable. The work rolls (1,2) with the supporting devices (9) associated therewith can be arranged in the rolling mill stand for horizontal displacement generally parallel to the web of material (3).
