Abstract
In a printing unit with two printing groups working together using the blanket-to-blanket method, in order to rotate the form cylinder and the transfer cylinder equally during circumferential register adjustment, the transfer cylinders are drive connected via helical gears and the transfer cylinders and the form cylinders of each printing group are drive connected via straight spur gears. The drive of the printing unit is carried out on one of the helical gears. Circumferential register adjustment of a printing group is carried out by movement of its helical gear.
