An eccentric roller control apparatus is intended to eliminate the adverse effect of the eccentric upper and lower back-up rollers against a product profile with high precision. The rolling weight sensors 7W, 7D sense each rolling weight of a working side and a driving side. The rotary angles of the upper back-up roller 4T and lower back-up roller 4B are sensed by the angle sensors 8T, 8B. The roller eccentricity sensor 14 serves to derive each of the amplitudes ATWn, BTWn, ABWn, BBWn, ATDn, BTDn, ABDn and BBDn as each roller eccentricity of the working side and the driving side, based on the sensed rolling weights PW, PD and the rotary angles THETA T and THETA B. Then, the depression operating unit 15W serves to derive the depression of the working side and add the derived value to the depressor control device 6W. The depression operating unit 15D serves to derive the depression of the driving side and add the derived value to the depressor control device 6D. |
