An apparauts for placing a printer-slotter in positions where it processes sheets of corrugated paper. The printer-slotter includes a feeding unit for feeding the sheets, processing units, and differentials connected with the processing units. The apparatus comprises a position detector for detecting the position of the kicker of the feeding unit, positioning controllers connected with a central control unit (CCU), and sensors detecting the angular positions of the rotating cylinders included in the printing units and in the creaser-and-slotter unit. The sensors are connected with the positioning controllers, respectively. The CCU compares the position of the kicker with the positions at which the processing units process the sheets. The CCU controls the differentials in such a way that the position of the kicker corresponds to the positions at which the processing units process the sheets.
An apparatus for determining the positions at which a printer-slotter processes paper, the printer-slotter including a feeding unit having a kicker, a plurality of processing units seperably connected in tandem to the feeding unit, a differential for each said processing unit to permit the positions at which the processing units process the paper to be adjusted separately, the feeding unit acting to feed paper, and a single drive motor for driving said processing units, said motor being operatively coupled to said processing units via gear trains, said apparatus comprising:
