Abstract A work roll bending system for profile control of continuous metal strip during rolling which is especially useful for retrofitting an existing rolling mill absent such feature to provide it with roll bending capabilities. The advantage of the system is its compactness of the structure in the vertical direction which facilitates its positioning between housing posts of the rolling mill where space in the vertical direction is often limited. Bending wings for exerting bending forces to work roll chocks with use of hydraulic cylinder and piston assemblies extend from the chocks in an intermeshing manner to allow wings from top and bottom work roll chocks to occupy the same horizontal plane without interference during at least some roll gap settings. That bending wing arrangement also allows for elimination of a 'layer' of hydraulic cylinder and piston assemblies which also reduces space requirements in the vertical direction.
