Abstract
A cylinder of a rotary printing press is provided with a journal which is supported for rotation in an eccentric bushing. The eccentric bushing is, in turn, shiftably positioned in a lateral side frame of the printing press. The cylinder is directly driven by an electric motor. This electric motor is mounted directly on the eccentric bushing. A compensation coupling, such as a clutch is placed between the electric motor and the cylinder.
