The invention relates to a method for straightening a metal strip (1) which is guided in the direction of transportation (R) through a straightening machine (2) and is straightened. In the straightening device (2), the metal strip (1) is impinged upon by a straightening force (F) which is applied by a plurality of straightening rollers (3) in the direction (N) which is perpendicular to the surface of the metal strip (1). According to the invention, prior to the metal strip (1) entering into the straightening machine (2), the thickness (d) of the metal strip (1) is determined and the position (a) of the straightening rollers (3) in the direction (N) which is perpendicular to the surface of the metal strip (1) is taken into account according to the determined thickness (d).

L'invention concerne un procédé pour dresser une bande métallique (1) qui est transportée dans un sens de transport (R) à travers une dresseuse (2), dans laquelle elle est dressée. Dans la dresseuse (2), la bande métallique (1) est soumise à une force de dressage (F) exercée par un certain nombre de galets de dressage (3) dans une direction (N) perpendiculaire à la surface de la bande métallique (1). Selon ce procédé, avant l'entrée de la bande métallique (1) dans la dresseuse (2), l'épaisseur (d) de la bande métallique (1) est déterminée et le positionnement (a) des galets de dressage (3) dans la direction (N) perpendiculaire la surface de la bande métallique (1) est réalisé en fonction de l'épaisseur déterminée (d).
