Beschreibung
Zusammenfassung:	The apparatus (1) has multiple endless belts (51) that are spaced axially apart along a transport drum (11). The belts are revolved around multiple rollers (54.1- 54.8) and partially wrapped around the drum, such that the cardboard cuttings (2,3) are pressed and conveyed against the drum surface from an inlet (14) to an outlet (15). A groove cutting tool (72) is arranged between the belts at a defined distance from the drum surface. The outlet is located at the upper vertex of the drum, such that the cardboard cuttings with cut grooves facing upward are delivered through the outlet.
