Title (EN) MULTI-ROLL METAL STRIP LEVELLER
(FR) PLANEUSE MULTI-ROULEAUX DE BANDE MÉTALLIQUE
Abstract:
(EN) The present invention relates to a metal strip leveller (B), said strip having a thickness (e) subject to a stress distribution, said leveller comprising: - a row of upper rolls (1, 3, 5, 7, 9...) and a row of lower rolls (2, 4, 6, 8, 10...), - the upper and lower rolls have parallel axes, longitudinally offset in a direction of line of passage (lp) and offset in height, in such a way as to define, by vertical imbrication of the rolls, an undulating path of the strip between said rolls, characterised in that at least two upper rolls ([1, 3]; [5, 7]) and two lower rolls ([2, 4]; [6, 8]) are arranged respectively above and below the line of passage, such that they form three vertical imbrication gaps, said gaps having a profile of non-linear imbrication values (Imbr) that are either convex or concave with respect to a profile of linear imbrication values (Imbr_lin) in the direction of the line of passage.
(FR) La présente invention décrit une planeuse de bande métallique (B), ladite bande possédant une épaisseur (e) soumise à un profil de contraintes, ladite planeuse comprenant : - une rangée de rouleaux supérieurs (1, 3, 5, 7, 9...) et une rangée de rouleaux inférieurs (2, 4, 6, 8, 10...), - les rouleaux supérieurs et inférieurs sont à axes parallèles, décalés longitudinalement selon une direction de ligne de passe (lp) et décalés en hauteur, de façon à déterminer, par imbrication verticale des rouleaux, un trajet ondulé de la bande entre les dits rouleaux, caractérisée en ce que au moins deux rouleaux supérieurs ([1, 3]; [5, 7]) et deux rouleaux inférieurs ([2, 4]; [6, 8]) sont disposés au-dessus et respectivement au-dessous de la ligne de passe, de sorte qu'ils forment trois écarts d'imbrication verticale, les dits écarts ayant un profil de valeurs (Imbr) non-linéaires d' imbrication de type soit convexe soit concave par rapport à un profil de valeurs linéaires d'imbrication (Imbr_lin) suivant la direction de ligne de passe.
