PCT No. PCT/AU84/00172 Sec. 371 Date Apr. 11, 1985 Sec. 102(e) Date Apr. 11, 1985 PCT Filed Sep. 7, 1984 PCT Pub. No. WO85/00998 PCT Pub. Date Mar. 14, 1985.A method for automatically controlling the thickness of product emerging from a rolling mill. Signals indicative of total roll force (F), rollgap position (S), angular position of one mill roll (v) and downstream product thickness (h) are utilized to obtain an output signal indicative of roll eccentricity affecting the true instantaneous rollgap position as a function of the measured mill roll angular position. The output signal may be use to compensate an estimate of instantaneous thickness of the product for the purpose of controlling the gap between work rolls. If preferred the output signal may be further processed to obtain an output signal indicative of the periodic roll eccentricity of a set of rolls having a common period of rotation or of a plurality of such sets.
