ABSTRACT:
In order to prevent waste and to improve the operating safety and easy operation of a device for making printed matter with changing prints or for adding further printing to a complete print, further printing units are provided associated with a printing unit having a common counterpressurer cylinder which is constantly connected with the main drive of the machine. The printing units are each provided with a normally passive acceleration motor and after completing the acceleration process are coupled (or decoupled) with the main drive of the machine by means of a coupling, having a movable coupling element which is operatively mounted independently of the print unit gear train and which is actuated by an adjustment device.
