L'INVENTION CONCERNE L'INDUSTRIE DU LAMINAGE.LE TRAIN DE CYLINDRES CONFORME A L'INVENTION EST CARACTERISE EN CE QUE LA SOURCE DE LIQUIDE14 EST UNE SOURCE A DEBIT REGLABLE MISE EN COMMUNICATION AVEC LES POCHES HYDROSTATIQUES13 DE L'UN DES DISQUES DE BUTEE9 DE L'UN DES CYLINDRES2A ET AVEC CELLES DU DISQUE DE BUTEE9 OPPOSE DE L'AUTRE CYLINDRE2B, ET EN CE QU'IL EST PREVU UNE SECONDE SOURCE DE LIQUIDE15 A DEBIT REGLABLE, MISE EN COMMUNICATION AVEC LES POCHES HYDROSTATIQUES 13 DES AUTRES DISQUES DE BUTEE9.L'INVENTION PEUT ETRE APPLIQUEE AVEC UNE EFFICACITE MAXIMALE AUX LAMINOIRS A PROFILES ET A FILS. The present invention relates to a roll assembly comprising grooved rolls. A neck of each roll is provided with a thrust shoulder placed in a thrust hydrostatic bearing mounted in a chock secured to a housing. The bearing comprises thrust disks each arranged on both end faces of the shoulders substantially parallel thereto. The sides of the disks facing the ends of each shoulder are fitted with hydrostatic pockets communicating with a fluid source. The fluid source, designed for adjustable delivery of fluid, communicates with the hydrostatic pockets of one of the thrust disks of a roll and of the other thrust disk facing it. There is another fluid source with adjustable delivery of fluid communicating with the hydrostatic pockets of the other thrust disks. This enables, by varying the deliveries of the fluid sources, the mutual disposition of the shoulders to be adjusted relative to the thrust disks and thereby permits control over the mutual arrangement of the rolls directly in the course of rolling.
