Abstract (en)

A method for manufacturing of cardboard boxes from at least two cardboard sheets, comprising the steps of laminating the sheets on one side with pre-printed paper sheets having a smoothness higher than the smoothness of the surface of the cardboard sheet, die-cutting the sheets to a desired shape of die-cut pieces, joining the folded flaps (21) of the die-cuts, thus forming a box in a flat form. Before joining the die-cuts with glue using a gluer, the flaps of the die-cuts are perforated using a rotary perforating head (11) equipped with a rotatable mandrel (14) having an adjustable height, on which there are replaceably mounted rotary toothed cutting blades (12), wherein the height of the mandrel is adjusted to a value resulting in the depth of the cuts from 10% to 90% of the thickness of the laminated cardboard.
