Abstract
A rotary press includes a plurality of printing units, a main shaft for driving all the printing units, a plurality of branch shafts branched from the main shaft, and drive units, each including a clutch and an individual drive motor disposed on the main shaft, for the respective printing units. Each printing unit is provided with an approach switch for detecting a particular position of a plate drum and a plate drum positioning device, in proximity to the particular position, for correcting the position of the plate drum to the particular position. Each drive unit is provided with an electromagnetic brake for stopping rotation of the plate drum in response to the approach switch and a main shaft positioning device on the respective sides of the clutch for correcting a phase deviation of a coupling section of the clutch.
