Abstract

Abstract 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 149 words
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: a position detector for detecting the position of the kicker of the feeding unit; and a central control unit which reads the position of the kicker from the output signal from the position detector and controls the differentials in such a manner that the positions at which the processing units process the paper correspond to the position of the kicker.
Claim 2
Independent Claim 149 words
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: a position detector for detecting the position of the kicker of the feeding unit; and a central control unit which reads the position of the kicker from the output signal from the position detector and controls the differentials in such a manner that the positions at which the processing units process the paper correspond to the position of the kicker.
Claim 3
Dependent Claim 16 words
The apparatus of claim 1, wherein said processing units include printing units and a creaser-and-slotter unit.
Claim 4
Dependent Claim 15 words
The apparatus of claim 1, wherein said differentials are connected with said processing units, respectively.
Claim 5
Dependent Claim 45 words
The apparatus of claim 1, further including position detectors for detecting the angular positions of rotating cylinders included in said processing units, and wherein said central control unit compares the position of the kicker with the angular positions of the cylinders of the processing units.
