Patent

CA 2598921

The invention relates to a method for manufacturing a metal strip (1), in which the metal strip (1) is guided over a number of rolls (2, 3, 4, 5) under such a strip stress (S), and is moved in a conveying direction (F), that it is largely flat at least between two rolls (2, 3). In order for it to be possible to inspect the strip in a simple and space-saving way, the invention provides for the inner tensile stresses which act in the metal strip (1) which is largely flat under tensile stress between the at least two rolls (2, 3) to be made optically visible and for the tensile stresses or tensile stress differences which are determined in this way to be utilized during the manufacture of the metal strip (1). Furthermore, the invention relates to an apparatus for manufacturing a metal strip.

L'invention concerne un procédé permettant de produire une bande métallique (1), selon lequel la bande métallique (1) est guidée par l'intermédiaire d'un nombre de rouleaux (2, 3, 4, 5) avec une telle tension de bande (S) et est déplacée dans un sens de transport (F), de sorte à être dans une large mesure plane, au moins entre deux rouleaux (2, 3). Afin de pouvoir surveiller la bande plus aisément et avec un encombrement réduit, il est prévu selon l'invention de rendre optiquement visibles les tensions de traction intérieures agissant dans la bande métallique (1), dans la bande métallique (1) sous tension de traction dans une large mesure plane entre les au moins deux rouleaux (2, 3) et d'exploiter les tensions de traction ou les différences de tensions de traction ainsi obtenues, lors de la fabrication de la bande métallique (1). L'invention concerne en outre un dispositif permettant de produire une bande métallique.
