[origin: EP2390017A1] The machine has an upper roller (2) and two lower rollers (3), which are rotatably mounted in a machine frame (6). The upper roller and/or the lower rollers are motor-driven and hydraulically adjustable. The upper roller comprises two bearing ends that are mounted in respective homogeneous carriages (4, 5). Hydraulic cylinders (7, 10) are arranged in pairs laterally to the upper roller for adjusting the carriages. The hydraulic cylinders lay in a plane vertical to a roller axis, and are assigned to the respective carriages in a same distance from the roller axis.
