Abstract

Large throw-off distances of the transfer cylinders in a double printing unit of a rotary printing machine operating on the rubber/rubber principle are achieved by enabling the two transfer cylinders to be set away from each other, and enabling the two form cylinders to be set away from the respective transfer cylinder. The form cylinder and the transfer cylinder of each printing unit have a drive connection via spur gears, the transfer cylinders are not in tooth engagement via their spur gears, and each printing unit has its own electric motor.
