A method of rolling a strip is provided. The method includes determining a value representative of the lateral position of the strip along a line transverse to a run direction downstream of each stand and calculating algebraic differences between the lateral positions and a reference position. A value of additional tilt is calculated from the algebraic differences to bring the algebraic differences below a predetermined threshold. Calculating the additional tilt values includes multiplying the algebraic differences by a gain matrix K that is determined by modeling relationships linking the algebraic differences and the tilts of the stand rolls. The additional tilt value is transmitted to each of the stands. The steps are repeated at predetermined time intervals until the strip is no longer gripped in the nip of the last stand of the rolling mill. A device for adjusting the lateral position of a strip is also provided.
