ABSTRACT:
A rolling mill for rolling metal strip moving in a horizontal rolling direction, has work rolls which engage the strip and are supported vertically by backup rolls through which drive is applied. The work rolls are supported in the horizontal rolling direction by support rollers contacting them at locations confined to intermediate regions between the work regions and bearings. The work rolls are shiftable in the horizontal rolling direction. To provide control of the horizontal forces during rolling, there are position control means for the support rollers operable to move and locate the support rollers so as to shift the work rolls to a predetermined location at which the vertical axial plane of the work rolls is offset in the horizontal rolling direction from the vertical axial plane of the backup rolls. The support rollers maintain the work rolls at the predetermined location during rolling.
