ABSTRACT:
Mechanism for the control of an inker unit, particularly on an accessory device for the numbering of sheets, for additional printing, and for the perforation of sheets on a printing machine. The mechanism provides an automatic control of the inker unit as well as a manual control thereof, and provides for the disengagement of the inker unit out of the working position in such a way as to form a convenient working space in the area around the numbering roller. On an eccentric shaft, which is arranged in the side walls of the printing machine, there are attached connecting levers which are slidably arranged on a carrier shaft which is provided with carriers which are rigidly connected with guides. On the guides there is adjustably arranged an accessory device including an inker unit, there being provided openings in the connecting levers in which are arranged slide elements which are located on pivots which are fixed in the side walls of the printing machine. The mechanism of the invention makes possible an automatic control of the inker unit in dependence upon the function of the printing machine. On the one hand this reduces the need of making a number of proof prints, and on the other hand requires a much smaller space for the operation of the printing machine and its accessory device.
