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).

Abstract: The invention provides an apparatus for the removal of liquid from the surface (0', 0") of a strip (B) conveyed from a strip processing machine, more particularly a rolling stand, by means of a gas jet (G1, G4, G5, Gzl, Gzr, G12-G18, G17', G18'), which has an outlet nozzle (2, 4, 5, 12-19) from which the gas jet (G1, G4, G5, Gzl, Gzr, G12-G18, G17', G18') emerges, and a suction opening (8a), via which the gas jet (G1, G4, G5, Gzl, Gzr, G12-G18, G17', G18') can be removed by suction mixed with the liquid, the apparatus enabling the surface of the strip to be adequately cleaned over its whole width. This is achieved by the feature that the gas jet (G1, G4, G5, Gzl, Gzr, G12-G18, G17', G18') is guided over the strip (B) in a flow (S, S2) directed towards at least one of the lateral edges (R) of the strip (B), and a suction opening (8a) is associated with that lateral edge (R) of the strip (B) at which the flow (S, S2) is directed.

Abstract: In a roll stand, more particularly a cluster roll stand, having guard plates (15, 21) which are disposed opposite one another in pairs above and below the strip (B) processed in the roll stand in the run-in zone (E) and run-out zone (A) of the roll stand and which extend into the roll stand substantially as far as the stand working rolls (1, 8) supported by supporting rolls (2-6a, 9-13a) and/or undriven supporting rollers, the lower guard plates (21) each being connected to the lower member (14) of the stand pivotably around a pivot (22) disposed axis-parallel with the working rolls (1, 8), the objective was to improve the protective effect of the guard plates (15, 21), while at the same time reducing expenditure on the lifting means required to lift the upper working roll (1).

Abstract: The invention relates to a positioning apparatus for coils, more particularly of metal strip, to be fitted on to a reeling drum. To determine on all sides the internal diameter of the coil 1 and its vertical and lateral position in relation to the reeling drum 2, the internal contour of the coil 1 is determined by a measuring head 13 which measures 360.degree. and, in dependence on the measured values to be obtained, by comparison with the corresponding measured values for the reeling drum 2 adjusting members are acted upon for the vertical adjustment of a lifting carriage 3 for the coil 1 and/or the lateral offsetting and/or the relative rotation between the coil 1 and the reeling drum 2.
