Abstract
Safety device for control or regulation systems of drive units of a printing machine having at least individual sub-aggregates thereof mechanically disconnected from one another, a plurality of motors connected via respective gear transmissions to the sub-aggregates for driving them in synchronous rotation, at least one measuring device for ensuring synchronous running of the sub-aggregates, and a device for controlling the rotary speed or the torque of the motors connected to the measuring device, further includes a clutch disposed between the gear transmissions of two of the at least individual sub-aggregates located adjacent one another, the clutch having clutch halves respectively connected to a synchronously running gearwheel of the respective gear transmissions, the clutch halves being connected to one another for transmitting torque when a preset rotational-angle difference between the clutch halves is exceeded.
