<p>The known driving system for a rotary press including a plurality of printing units (1, 2, 3), a main shaft (5) for driving all the printing units, a plurality of branch shafts (11) provided as branched from the main shaft, and drive units each consisting of a clutch (7) and an individual drive motor and disposed on the main shaft for the respective printing units, is improved so as to be adapted for automation of a plate exchange work, to save time and labor for exchanging a plate, and to increase a working efficiency of a rotary press. The improvements reside in that each of the printing units (1, 2, 3) is provided with an approach switch (16, 16') for detecting a particular position of a plate drum (9, 9') and a plate drum positioning device (18) for correcting the position of the plate drum to the particular position in the proximity of the particular position of the plate drum, and that each of the drive units 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 clutch coupling section.</p> |
