Abstract

L'invention concerne un transporteur à rouleaux (1, 1') pour le transport d'un matériau laminé (5, 5') dans un train de laminage, le transporteur à rouleaux (1, 1') présentant au moins deux segments d'entraînement entraînés par le biais de convertisseurs (2a, 2b). En l'occurrence, au moins un segment partiel (c) du transporteur à rouleaux (1, 1') peut être commuté au moyen d'une unité d'inversion (3) à un premier convertisseur (2a) et/ou à un deuxième convertisseur (2b). De ce fait, le train de laminage selon l'invention est plus flexible que dans les solutions connues, pour un nombre de convertisseurs inchangé.
