Abstract
The invention concerns a 4-high/6-high/18 HS cassette-type roll stand in which bending force is transmitted to bending journals (6) of roll inserts (7) by piston-cylinder units that are connected with Mae West blocks (3). Here, the piston at the piston rod (1) is fixedly connected with the Mae West block (3) and the cylinders (4) fit around the bending journals (6) at the inserts (7) of the rolls, so that thereby bending force can be transmitted directly to the bending journals (6) of the roll inserts (7).
