Abstract: A box laminating machine with two rubbing-down devices that lie opposite of one another with respect to the box to be covered, wherein each rubbing-down device has a counter-holder that plunges into the box and a rubbing-down element that sweeps over the wall to be covered, which is supported against the counter-holder. The rubbing-down operation of opposing walls takes place successively, wherein a movement of the box relative to the counter-holder takes place perpendicular to the wall to be rubbed down.

Abstract: A method and a device for individually supplying rollable discoidal components stocked in a reservoir in a supply position, wherein one component is respectively held in the supply position with the aid of a magnetic field of the device.

Abstract: The apparatus (1) includes a horizontally supported transport drum (11), spaced-apart endless belts (51) that revolve around rollers (54.1 to 54.8) and are partially wrapped around the transport drum (11) such that an infeed (14) and an outlet (15) are formed and the cardboard cuttings (2, 3) are pressed against and conveyed on the drum. Groove cutting tools (72) are arranged between the belts (51). 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: An apparatus (1) for grooving cardboard cuttings (2, 141) while the cuttings are transported past at least one groove cutting tool (72?, 72?, 72??). The tool or tools are situated on a guide element (78, 80, 130) that can be moved relative to the transport device during the operation of the grooving apparatus. During a grooving operation, the position of the groove cutting tool along the surface of the cutting and/or its distance from the transport device, can be varied such that completely new designs of mechanically grooved cardboard cuttings can be realized. According to the grooving method at least one groove cutting tool is moved transverse to the transport direction of the cardboard cuttings while the cardboard cuttings are transported past the groove cutting tools.

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).
