Abstract

L'invention concerne une installation industrielle (1), un dispositif de commande et/ou de réglage (5), un code de programme (7) lisible par machine, un support d'enregistrement (6) et un procédé pour commander et/ou régler un mouvement de glissement d'un rouleau (3, 3-1, 3-2) relativement à une bande (B), notamment un feuillard laminé à froid dans une installation de métallurgie, ce feuillard étant guidé à une vitesse réglable à travers un ensemble de rouleaux (2) comportant le rouleau (3, 3-1, 3-2) et au moins un autre rouleau (3, 3-1, 3-2). Selon l'invention, l'occurrence d'un mouvement de glissement est surveillée (21) par la saisie d'au moins un paramètre technique de fonctionnement du rouleau (3, 3-1, 3-2) et, en cas de mouvement de glissement du rouleau (3, 3-1, 3-2), une vitesse circonférentielle réelle du rouleau (3, 3-1, 3-2) et/ou d'au moins un autre rouleau (3, 3-1, 3-2) et/ou la vitesse du feuillard sont modifiées (24, 25, 26, 27, 34) de façon que la vitesse circonférentielle réelle du rouleau (3, 3-1, 3-2) glissant et la vitesse du feuillard se rapprochent l'une de l'autre, permettant ainsi de détecter le glissement d'un feuillard relativement à un rouleau dans une installation industrielle et de réduire voire de supprimer ce glissement, notamment pendant le fonctionnement de l'installation.
