A device for adjusting the profile of a roll with a deformable wall (1) mounted rotatably about a central shaft (2). Blocks (3) are aligned along the axis between a bearing face (21) of the shaft (2) and the cylindrical inner face (12), and hydraulic thrust jacks (4) are arranged between the face (21) and a bearing face (32) of the blocks (3) at the opposite, for adjusting the radial position of each block (3). The axial and transverse dimensions of each block (3) are different, and its plane and rectangular bearing face (32) works together with a single hydraulic jack (41) having an oblong working cross-section covering the greater part of the face (32). The invention applies especially to rolling-mill cylinders. |
