A device for engaging and disengaging or throwing-off printing unit cylinders in a printing entity of a rotary printing press for printing a web of material, the printing entity including a lower and an upper printing unit, and one of the printing unit cylinders having a stationary mounting support in one of the printing units of the rotary printing press, includes a first adjusting unit for adjusting printing unit cylinders of the printing entity which are formed as printing form cylinders, and a second and eccentric adjusting unit for adjusting one of two of the printing unit cylinders of the printing entity which are formed as transfer cylinders, so that the printing unit cylinders of each of the lower and the upper printing units, respectively, are in mutual engagement, while the transfer cylinders of the respective lower and upper printing units are disengaged from one another.

Eccentric device for adjusting printing unit cylinders including a

Device for adjusting printing-unit cylinders in a printing unit of a rotary printing press for printing on both sides of a material web, the printing-unit cylinders including printing-form cylinders with exchangeable printing forms, one of the printing-unit cylinders being held stationary in the printing unit, includes an auxiliary adjusting unit for maintaining a gap traversible by the material web, the gap being formed between outer cylindrical surfaces of two of the printing-unit cylinders disposed adjacent to a path of the material web through the printing unit, the gap being maintainable by the auxiliary adjusting unit independently of adjusted positions of others of the printing-unit cylinders.
