Abstract: The invention pertains to a device and a method for producing hollow bodies that are open on one side of predominantly plane material blanks by erecting and gluing their sides along prepared bending edges, wherein said device features a shaft that is arranged directly downstream of the erecting elements and accommodates the hollow bodies in order to cure the glued joints, and wherein the products are spaced apart from one another during their transport within the shaft. The transport device provided for this purpose preferably acts directly upon the glued edges or areas located adjacent thereto such that the glued joint is continuously stabilized during the curing process.

Abstract: In order to simultaneously cut several parallel grooves into material cuttings at a short distance from one another, the groove cutting machine features a horizontally arranged transport drum and at least one groove cutting tool with several knife sets for respectively cutting a groove, wherein the relative position between the knife sets of a groove cutting tool is variable in the axial direction of the transport drum.

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.

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).

Abstract: The box (17, 21, 31, 41, 51) is created on the basis of a multi-element lined box part (1), to which two separate and likewise lined sidewalls (13, 14) are glued. The multi-element box part (1) comprises a bottom (10), as well as the two other sidewalls (11, 12). The two separate third and fourth sidewalls (13, 14) are glued on by means of straps (4.1, 4.2) flush with or slightly set back to the edges of the multi-element box part (1), wherein the multi-element box part (1) is quasi folded around the third and fourth sidewalls (13, 14). This results in a rigid box (17, 21, 31, 41, 51) that in its simplest form consists of an upwardly open case.

Abstract: The invention pertains to a conveyor with profiled cheeks consisting of at least one profiled member that is manufactured from light metal and contains longitudinal hollow spaces that are partly realized in the form of sliding block channels, and of a cover for closing a cable channel arranged in the cheek. The invention proposes that the profiled member has an L-shaped base cross section with an upper limb that points outward in the operative position, that a sheet metal member is mounted on the base part in order to form the lower limb of the C-shaped base cross section of the cheek, wherein the sheet metal member contains openings that are spaced apart from one another in the longitudinal direction, and that the cover is removably arranged on the two limbs. Cables and lines can lead into and out of the closed cable channel through the openings without having to produce openings on the profiled member or the cover by way of mechanical processing.
