Title
(DE) ROLLENAUSGLEICHER UND PLATTENMATERIALKORREKTURVERFAHREN DAMIT
(EN) ROLLER LEVELER AND PLATE MATERIAL CORRECTION METHOD USING SAME
(FR) NIVELEUR À ROULEAU ET PROCÉDÉ DE CORRECTION DE MATÉRIAU DE PLAQUE L'UTILISANT
Abstract
(EN)
A roller leveler (100) includes: a leveling roll unit (20) having a plurality of leveling rolls (6, 8a, 8b) configured to rotate so as to pass a plate (P) while sandwiching and pressing the plate; a pushing cylinder (4a, 4b) provided at each of an entrance side and a discharge side of the leveling roll unit (20), at which the plate enters and is discharged, respectively, and configured to press the plate (P) via the leveling rolls (6, 8a, 8b); and a driving mechanism (15) configured to rotate the leveling rolls (6, 8a, 8b) to pass the plate (P). At least one (8b) of the plurality of leveling rolls (6, 8a, 8b) has a stepped structure, including a lateral center portion (21) with a large diameter, corresponding to a center portion of the plate with respect to a plate width direction, and lateral end portions (22) with a small diameter, corresponding to edge portions of the plate with respect to the plate width direction.

(FR)
La présente invention concerne un niveleur (100) à rouleau équipé : d'une unité (20) de rouleau de nivellement qui présente plusieurs rouleaux (6, 8a, 8b) de nivellement, qui intercalent un matériau de plaque (P) entre eux et pivotent, de manière à transférer le matériau de plaque, tout en pressant contre le matériau de plaque; de cylindres de pression (4a, 4b) qui font pression contre le matériau de plaque, à l'entrée et à la sortie de l'unité (20) de rouleau de nivellement par le biais des rouleaux (6, 8a, 8b) de nivellement; et d'un mécanisme d'entraînement (15) qui entraîne les rouleaux (6, 8a, 8b) de nivellement en rotation, transférant ainsi le matériau de plaque (P). Au moins un rouleau (8b) de nivellement, parmi les multiples rouleaux (6, 8a, 8b) de nivellement, est une structure en escalier, qui présente une partie centrale (21) dans la direction de la largeur au diamètre supérieur, correspondant à la partie centrale du matériau de plaque, dans la direction de la largeur et des parties (22) d'extrémité dans la direction de la larguer au diamètre inférieur, correspondant aux extrémités du matériau de plaque dans la direction de la largeur.
