Abstract

A roll stand with multiple rolls for rolling strip-shaped rolling stock has a roll frame and upper and lower working rolls mounted on the roll frame in a common vertical roll axis plane, wherein the rolling stock is guided between the upper and lower working rolls forming a roll set. Upper and lower support roll insert parts are mounted on the roll frame. Two upper support rolls are mounted in the upper support roll insert parts and support the upper working roll, and two lower support rolls are mounted in the lower support roll insert parts and support the lower working roll. The two upper and the two lower support rolls are arranged symmetrically to the vertical roll axis plane, respectively. Working roll bending devices are mounted on the roll frame and act on the upper and lower working rolls. Balancing devices are mounted on the roll frame and advance and balance the upper and lower support rolls. The two upper and two lower support rolls are axially moveable independently from one another relative to a vertical center plane of the roll frame, extending perpendicularly to the vertical roll axis plane, by same or different axial displacement lengths in order to compensate roll …
