Abstract
The present invention relates to a cluster mill for strip material, having working rolls (1, 2), which are supported, via possibly existing intermediate rolls (4, 5), on backup rolls (6, 7, 8, 9-16b), which are each rotatably mounted jointly on a support axle (17, 18, 19, 20), divided into at least three longitudinal sections (L1, L2, L3), and having at least one adjustment device, which is assigned to at least one of the support axles (18) and includes actuator drives (35, 36, 37), each one of which is assigned to one of the longitudinal sections (L1, L2, L3) of the support axle (18) at each case and, via a group (G1, G2, G3) of actuators (24, 25, 26; 27, 28; 29, 30, 31), which are coupled to one another via a coupling element (32, 33, 34) in regard to their movement in relation to the support axle (18), apply a force, directed transversely to the longitudinal direction of the support axle (18), to the respective longitudinal section (L1, L2, L3) to correct the roll gap (3) between the working rolls (1, 2).
