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. The inter-sheet spacing device comprises a transport section for transporting the small-size corrugated paperboard sheets from the folder-gluer to the counter-ejector, and a speed adjustment section for adjusting a transport speed in at least one of the folder-gluey and the transport section so that the transport speed in the transport section becomes greater than that in the folder-gluey.
