PURPOSE:To facilitate the cleaning work by automatically and intermittently rotate a rotary cylinder by the operation of a start switch. CONSTITUTION:When a cleaning switch Sc and a start switch Ss are turned ON according to the start of the cleaning work, a power source E1 is supplied to each circuit following a relay RY1 with a contact RYS3. A timer TM2 operates an electromagnetic switch MS only during the set time to rotate a main motor M of a printing press. As the timer TM2 is up in the time, a timer TM3 starts and with the time up of the timer TM3, the timer TM2 is started again through the timer TM1. Therefore, the stoppage time is determined by the set time of the timer TM3, while based on the stoppage time and the timer TM2, an AC power source 3phiAC is intermittently applied to a motor M according to the rotation time. |
