- Fig. 2 is a front side view of the left in Fig. 1 shown
- the present invention can basically be implemented in printing presses of various types, so that no specific printing press is completely shown in the figures. However, special advantages arise with format-variable flexographic printing machines.
- Figure 1 shows as a roll 1 of a printing unit 2, the format cylinder or the anilox roller of a flexographic printing press, which is rotatably mounted on opposite bearing sides 3 and 4 on a frame 5 about its longitudinal axis.
- the roller 1 On the first bearing side 3, which forms the drive side, the roller 1 is advantageously rotatably supported by a bearing 6 which is fixed to a bearing block 7.
- the bearing block 7 is mounted by means of a linear guide 8, which is formed in the illustrated embodiment as a double-rail track bed guide, longitudinally displaceable transversely to the roller longitudinal axis 9 on a bearing plate 10.
- the linear guide 8 allows a radial advancement of the roller 1 to a counter-pressure cylinder not shown specifically or a driving away of the roller 1 of this impression cylinder.
- the linear guide 8 is associated with an adjusting spindle 11 which acts between said bearing plate 10 and the bearing block 7.

- the inner recess of the eccentric sleeve 17 is offset radially to the eccentric rotation axis 18, cf. FIG. 2. If the eccentric sleeve 17 is rotated in the bearing recess 19 in the bearing carrier 16, as indicated by the arrow 20 in FIG. 2, the bearing 15 experiences a height adjustment perpendicular to the roller longitudinal axis 9.
