ABSTRACT:
A roll stand with backing rolls and work rolls for rolling sheets and strips, in which at least the upper and lower work rolls mounted in chucks inside of housing windows formed between housing columns of the roll housing can be moved out of their shared vertical plane horizontally in opposite directions by movement drives effectively associated with the roll chucks into positions wherein the vertical planes that pass through the axis of roll of the upper work roll and of the lower work roll intersect. This is achieved by the fact that on the inner and outer sides (which are opposite to each other and run parallel to the direction of roll) of each housing column, a movement and a swivel bearing are arranged for one of two substantially horizontal beams. The beams are parallel, connected to each other and extend on both sides past the housing columns on one side, the beams extend into the housing window and, on the side facing away from the housing window, out of the roll housing. The respective ends of two beam pairs extending into the housing windows on one housing side support the chucks of the upper and the lower work roll so that the chucks are synchronously adjustable on both sides in the vertical and the horizontal directions. The other protruding ends of the beam pairs connect to the movement devices and to deflecting devices.
