Abstract

L'invention concerne un ensemble rouleau de traction comportant un premier rouleau de traction (09) et au moins deux anneaux de traction (11,12), disposés de manière décalée dans le sens axial du premier rouleau de traction et respectivement réglables contre le premier rouleau de traction, ou bien des sections d'un deuxième rouleau de traction. Selon l'invention, à l'intérieur de l'ensemble rouleau de traction est prévu au moins un rouleau collecteur (21) réglable contre le premier rouleau de traction, le premier rouleau de traction et le ou les rouleaux collecteurs (21) étant parallèles dans l'axe les uns par rapport aux autres. Le ou les rouleaux collecteurs (21) comportent un entraînement et sont montés rotatifs, entraînés par l'entraînement, lorsqu'ils sont en état de fonctionnement débrayé du premier rouleau de traction.
