Rolling mill incorporates a system for the adjustment of tightening and cambering. The rolling mill incorporates a rolling cage surrounded by a lower group and upper group of rolls. Each group of rolls has at least two lines of thrust supports, each line incorporating rollers (41.1 - 41.6) and support bearings (30.2 - 30.6) (30.1 - 30.7) between the rollers and at each end of the line of thrust supports. Each bearing is thrust against the rolling cage by some seats (S1 - S7) in the form of cylindrical sectors. Each roller is carried by a shaft section forming staging (38.1 - 38.7) off-centred with respect to two end journals (37.1 - 37.6 and 33.2 - 33.7), each journal being mounted to rotate in a support bearing. One of the journals (33.2 - 33.7) is provided with a toothed section (43.2 - 43.7) for controlling its angular position in the bearings by means of a rack (44.1 - 44.6) tangent to the toothed section. |
