A method controls a folding box machine having a plurality of machining stations and a plurality of control devices for controlling the quality of folding boxes. Each control device controls different quality features of each folding box, and each control device transmits the result of the control to a control unit. Target values are stored in the control unit in order to classify the control results into results which meet the quality standard and results which do not meet the quality standard, and a folding box is discharged depending on an evaluation. The method advantageously reduces waste.

A packing method and unit (26) for producing a rigid package (1) with a hollow rib (12; 13); an end portion of a blank (21) is folded about a contrasting body (36; 39) onto a panel (11′) of the blank (21) to form the hollow rib (12; 13); a fastening tab (16; 19), which forms the end part of the end portion, is glued to the panel (11′) to stabilize the hollow rib (12; 13); and the contrasting body (36; 39) is extracted from the hollow rib (12; 13) once the end portion is folded.

The invention relates to a method for folding a corrugated cardboard blank (1) intended to form a folded box, the method comprising the following series of steps:

i) supplying a blank (1) comprising at least one longitudinal crease (11);
ii) applying a liquid to the longitudinal crease (11) so as to make the corrugated cardboard more flexible at the location of the longitudinal crease (11), the application being performed by means of a liquid application arrangement (130) comprising a liquid-ejection nozzle (134) provided with a liquid outlet;
iii) folding the blank (1) around the longitudinal crease (11);
wherein an aspiration of liquid is produced inside an aspiration compartment (163) of the liquid application arrangement (130) during step ii). The aspiration making it possible to remove any excess liquid which might not have been absorbed by the cardboard and/or the cardboard dust produced.

A method and a sealing device for sealing a joint (5; 31) between two end sides (3, 13) of two contiguous panels (1, 11). The method comprises the steps of: holding (S1) an end side (3) of a first panel (1) close to an end side (13) of a second panel (11), whereby the joint (5; 31) to be sealed is defined by the adjacent end sides (3, 13) of the two panels (1, 11); sealing (S3) the joint (5; 31) with a first and a second adhesive tape (15, 17) by providing a first tape (15) to a first face (19) of the two panels (1, 11), said first tape (15) sealing the joint (5; 31) and being provided in the direction of the joint and providing a second tape (17) to a second face (21) of the two panels (1, 11), wherein the second face (21) of the two panels (1, 11) is the opposite face to the first face (19) of the panels, said second tape (17) sealing the joint (5; 31) and being provided in the direction of the joint.

A tool-holder column for a unit for converting a flat substrate that has two upper bearings (14, 16) each for supporting one end of an upper rotary tool (10), and two lower bearings (15, 17) each for supporting one end of a lower rotary tool (11), the flat substrate being movable longitudinally between the upper rotary tool (10) and the lower rotary tool (11), the bearings (14, 15, 16, 17) being vertically movable in opposite directions on either side of the longitudinal direction (L) of movement of the flat substrate, and a common drive for the bearings (14, 15, 16, 17) allowing the bearings (14, 15, 16, 17) to be moved simultaneously by one and the same distance in opposite directions, and including a screw device (25), the bearings (14, 15, 16, 17) being mounted one above another on the screw device (25) such that the rotation of the screw device (25) causes the linear movement of the bearings (14, 15, 16, 17) in opposite directions.

The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

An article of manufacture for use in constructing a three-dimensional discard cup comprising a substantially square flexible substrate having a front side and back side, a first corner, a second corner, a third corner and a fourth corner. A center and two pairs of opposing corners, wherein the flexible substrate having diagonal mirror image cut lines in the shape of an

L, a score line diagonal near the first corner and the third corner. A first wall is created by folding inward along the first score line and the flexible substrate is rotated 180 degrees preparing for the next fold along the second score line. A second wall is created by folding inward along the second score line, and the first wall the second wall are formed creating a pouch.

A box making machinery and a corrugated board running register method, include a feeding unit, a processing apparatus which carries out processing on a corrugated board, a running register device which adjusts the processing position of the processing device in a carrying direction of the corrugated board, and a control device which controls the running register device, wherein the control device includes a carrying misalignment amount calculation unit which calculates the carrying misalignment amount of the corrugated board from the feeding unit to a preset predetermined carrying position, and a control unit which adjusts the processing position of the corrugated board to be processed next using the running register device on the basis of the carrying misalignment amount after processing of the corrugated board has finished.
