ABSTRACT:
Device to absorb the axial loads generated on the rolls in a rolling stand (11) having a pair of working rolls (12a,12b), a corresponding pair of back-up rolls (15a,15b) and at least an intermediate roll (14) located between a working roll (12a) and a corresponding back-up roll (15a), in said device holding means (16, 40, 41) are provided to support the axial loads on the back-up rolls (15a,15b) and/or the working rolls (12a,12b) caused by the crossing of said at least one intermediate roll (14), so that the axial loads are discharged onto elements with very low rolling friction, totally or almost totally annulling the hysteresis relating to the vertical movements of the back-up rolls (15a,15b) and working rolls (12a,12b) and the relative chocks (26).
