ABSTRACT:
The invention relates to a rolling stand of the type with crossed rolls, for flat products, which comprises at least two working rolls opposed to one another. These rolls are angularly adjustable and such an adjustment is effected by rotating them about a vertical axis of the stand.
Advantageously, the actuators which serve to maintain the working rolls at a predetermined distance from one another following to the thickness of the material to be rolled, are solid with the rotations of the rolls themselves: in this way the stresses which the rolls transmit to the actuators during rolling are independent of their angular adjustment and are therefore always balanced.
