IPC: B41F21/10
Filed: 1990-04-24
Abstract: 1. To eliminate displacement errors in multicolour printing in sheet-fed rotary printing machines, corrections are carried out by inclination of sheet transport drums. The drive must not be influenced by the inclination. 
<??>2. A sheet transport drum 1 consisting of support disks 17, 18 and gripper bars 6, 7 is mounted on a drum shaft 16. The support disk 18 is located with a flange 22 on an adjustment eccentric 19. The support disk 17 has on its flange 21 a curved bearing surface 20 about which the drum body can be inclined in relation to the drum shaft 16 by means of the adjustment eccentric 19. Alternatively, the drum body can be coupled to the drive-side bearing flexibly.
