In order to allow a visual inspection of the cut grooves (3a) from above during the operation of the apparatus, the outlet (15) is situated in the region of the upper vertex of the transport drum (11). The delivery of the grooved cardboard cuttings (3) at the upper vertex of the transport drum (11) also results in an ergonomically advantageous removal height.

Abstract: A device (1) for grooving cardboard cuttings (2, 3) that features a driven, horizontally supported transport drum (11) and spaced-apart endless belts (51) that revolve around rollers (54.1 to 54.8) and effectively convey the cardboard cuttings (2, 3) by pressing them against the drum shell. Groove cutting tools (72) are arranged between the belts (51) at a defined distance from the drum shell and make it possible to produce grooves with essentially triangular cross section in the cardboard cuttings (2). In order to adjust the aperture angle of the grooves independently of one another, the adjustment of the angle within the respective groove cutting tool (72) is realized by curved guides (77). The center of curvature (81) of the curved guide (77) lies in the region of the drum shell, as well as in the region of the blade tip (71a) of the knife (71), such that the aperture angle and the depth of the groove can be adjusted independently of one another.

Abstract: In a device for feeding book blocks (2) into the infeed channel (11) of a subsequent processing arrangement with a book block feeder (30) that essentially feeds the book blocks (2) into the infeed channel (11) vertically from above transverse to the conveying direction of the infeed channel (11), at least one push-out unit (51) is driven separately of the at least one pusher (14) of the infeed channel (11) and provided in the infeed channel (11) in the region of the book block feeder (30). The separate drive makes it possible to define a push-off motion that allows a gentle start of the push-out unit (51) relative to the book block (2) to be pushed off on the one hand and a synchronous transfer to the continuously moving pusher (14) of the infeed channel (11) on the other hand.
