An improved roll shifting and crossing system comprising a rolling mill housing, at least one pair of upper and a lower work rolls (1,2) having roll necks (4,6) mounted in chocks each chock (7) is supported by a pair of upside and downside Mae West blocks (8,9) mounted in the housing, each of said chocks (7) and the associated Mae West blocks (8,9) having between them a pair of opposed contacting surfaces (15) defining an angle beta with respect to the roll axis and which surfaces (15), upon axial shifting of the work roll (1 or 2), causes at least one roll chock (7) of each roll (1,2) simultaneously to move in a direction perpendicular to the roll axis resulting in crossing of each pair of rolls (1,2) at an angle, alpha , to the pass line of the mill, and means (12) to axially shift the work rolls. <IMAGE> |
