摘要

Device (20) for adjusting a roller (21) arranged in a roller holder (27) positioned on a frame holder (26) comprises at least one actuator (34). The actuator has at least one pressure chamber (36) impinged upon by pressurized material and arranged in a gap (33) between the roller holder and the frame holder. Preferred Features: A height (h36) of the pressure chamber in the radial direction of the roller is shorter than a width (b36) of the pressure chamber in the axial direction of the roller and/or a length of the pressure chamber in the peripheral direction of the roller. The ratio of width and/or length of the pressure chamber to the height of the pressure chamber is greater than 3.
