eccentricity 27 and 28 of the support disks 37 and 48 after the drive motors 47 61 have been switched on due to the fact that only two support disks 33 and 37 or 48 and 49 act in pairs against each other only small rotational forces are required to perform the adjustment of the cylinders 14 24 on the printing cylinder 1 in the course of this adjustment the shaft journals 4 17 and 22 of the cylinders 1 14 and 24 respectively turn together with the inner raceways shown for example by the inner raceway 35 at the support disk 34 while the outer raceways shown by means of the outer raceway 40 at the support disk 34 are placed on top of each other such that they do not move when pressed against each other in pairs if now the right printing cylinder 2 is to be operated the holder 26 is turned to the right by means of the eccentric bearing 25 as seen in fig2 so that the circumference of the counter pressure cylinder 24 now contacts the circumference of the printing cylinder 2 furthermore the eccentric support disk 38 of the counter pressure cylinder 24 is frictionally engaged with the concentric support disk 34 of the printing cylinder 2 the concentric support disk 52 which is also located on the shaft journal.
