Abstract: Provided is a corrugated paperboard box making machine which comprises: a cutting device for cutting one corrugated paperboard sheet into a plurality of small-size corrugated paperboard sheets along a direction perpendicular to a predetermined transport direction; a folder-gluer for bending and gluing each of the cut small-size corrugated paperboard sheets; a counter-ejector for stacking the glued small-size corrugated paperboard sheets to form a batch of the small-size corrugated paperboard sheets; and an inter-sheet spacing device for spacing the small-size corrugated paperboard sheets apart from each other, between the folder-gluer and the counter-ejector.

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.
