Abstract

La présente invention concerne une bande (1) présentant des arêtes de bande (1A, 1B), qui est laminée dans une cage de laminage (3). Des dispositifs de mesure de force (5) permettent de détecter des forces d'appui (FA, FB) qui surviennent des deux côtés d'un dispositif de déviation de bande (4) contigu à la cage de laminage (3) vu dans un sens de déplacement de la bande (x). Un dispositif de détection de position (6) permet de détecter une position latérale (p) de la bande (1) par rapport à une ligne médiane de cannelures (7). Des valeurs représentant les forces d'appui (FA, FB) et la position (p) de la bande (1) sont transmises à un dispositif de détermination (8). Le dispositif de détermination (8) détermine en fonction des forces d'appui (FA, FB) et de la position (p) de la bande (1) des tractions (ZA, ZB) survenant dans les arêtes de bande (1A, 1B) et en fonction des tractions (ZA, ZB), une grandeur réglante (S) influençant les tractions (ZA, ZB) de la cage de laminage (3). La grandeur réglante (S) est déterminée de façon à adapter les tractions (ZA, ZB) les unes aux autres. La grandeur réglante (S) est sortie par le dispositif de détermination (8) sur la cage de laminage (3).
