Abstract

The present invention relates to a roll-holder cartridge for a rolling mill 20. The cartridge 24 comprises two side walls 26, a plurality of roll-lever units 30, two adjusting rings 28 and an adjusting actuator 32. Each side wall of the cartridge comprises a plurality of first seats 260; each adjusting ring comprises a plurality of second seats 280; and each one of the roll-lever units is mounted on the cartridge so as to be able to pivot about a pin 300, each end of each pin being housed in the axial direction inside a first seat and a second seat, respectively. Moreover, the first seats allow a displacement of the respective pins in a purely tangential direction t, the second seats allow a displacement of the respective pins in a purely radial direction r, and the two adjusting rings may be rotated about the axis X by means of the adjusting actuator. The invention also relates to a rolling stand 22 comprising the cartridge described above and a rolling mill comprising a plurality of rolling stands 22.
