Abstract

L'invention concerne un ensemble de rouleaux (1) destiné à un dispositif de laminage, qui comprend au moins un ensemble de rouleaux de travail (5) pourvu d'au moins un rouleau de travail (5.1, 5.2), entraîné par un rouleau d'entraînement (6, 7) immédiatement adjacent, pour mettre en forme un matériau à laminer et au moins un ensemble de rouleaux de support (8) pourvu d'au moins un rouleau de support primaire (8.1 à 8.4) destiné à supporter l'ensemble de rouleaux de travail (5). Selon l'invention, l'au moins un rouleau de support primaire (8.1 à 8.4) comporte une pluralité de segments de rouleaux de support primaires (8.1.1 à 8.1.4, 8.2.1 à 8.2.4, 8.3.1 à 8.3.4, 8.4.1 à 8,4.4) disposés axialement les uns à la suite des autres.
