    摘要： The invention relates to a method for rolling a strip (B) inside a rolling mill for metal products that comprises at least two cages in which the strip (B) is simultaneously clamped, said method comprising: adjusting the side position of said strip (B) by simultaneously determining, downstream from each of the rolling mill in which the strip is clamped, a value representative of its side position along a line transverse to the movement direction, and calculating the algebraic deviations (Δxp) between the side positions and the reference positions (6); based on said deviations (Δxp), calculating the value (Sp) of the additional tilting to be applied to each of the rolling mill cages in which said strip (B) is clamped in order to reduce said algebraic deviations (Δxp) under a predetermined threshold, the calculation of said additional tilting values (Sp) being carried out by multiplying said deviation values (Δxp) by a K gain matrix determined by modelling the relations binding said deviation values (Δxp) of the strip and said tiltings (Sp) of the support cylinders of the rolling mill; transmitting to each of the rolling mill cages the respective setpoint of additional tilting (Sp); and repeating these operations at predetermined time intervals until the strip (B) is no longer clamped in the last cage of the rolling mill. The invention also relates to a device for implementing this method, and to a rolling mill provided with at least one such device.
