ABSTRACT:
A precision roll stand includes a roll housing absorbing the rolling forces. In the roll housing rolls constituting a roll pair with their roll chocks are mounted so as to be rotatable and mutually adjustable by an adjustment device which changes the axial distance between the pair of rolls. A drive housing including a roll drive is connectable with the roll housing while establishing a drive connection of the roll drive with the rolls and being removable from the same while undoing the drive connection. In order to produce rolled products exhibiting extremely high measuring accuracies and to be able to exchange the rolls quickly and without difficulty, the roll housing has a frame which is open in the direction of adjustment of the rolls and contains and guides the chocks of the rolls. A crosshead for closing the frame carries the adjustment device designed as a pressure medium cylinder and is rigidly connectable with the frame. The drive housing is supported on the crosshead.
