• Roll stand

The invention relates to a pre-tensioned, in particular control-less v.'alz _or frame with .binijaustücke supported against the door head, in which the rollers are mounted.

In the known roller squares of this type, devices for adjusting the roller gap, for example hydraulic cylinders or adjusting screws, are provided between a kuerhaupt and the corresponding chock. Furthermore, a rolling mill is known in which screw spindles are arranged between the chocks for setting the roller gap.
