An apparatus (1) for grooving cardboard cuttings (2, 3) features a transport drum (11), spaced-apart belts (51) that revolve around rollers (54.1 to 54.8) such that an infeed (14) and an outlet (15) are formed. Groove cutting tools 72 are arranged between the belts (51) at a defined distance from the drum surface. The belts (51) and/or the groove cutting tools (72, 72.1 to 72.6) are situated on a first or second carrier (31) that can be displaced back and forth between a working position and an idle position radially to the transport drum (11). Another embodiment features several third carriers (52.1 to 52.7) that can be separately displaced relative to one another and to the transport drum (11) and feature at least the rollers (54.1 54.8) intended for guiding and tensioning a preferably individual belt (51). |
