A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

The invention relates to a method for producing a blank for a packaging item having a cellulose-containing base material with at least one line from the group of folding, crease, cutting, scored and/or bending lines, wherein the at least one line is defined at least in sections by the application of water and/or of at least one hygroscopic substance to the base material. The invention also relates to a blank for producing a packaging item including a cellulose-containing base material having at least one line from the group of folding, crease, cutting, scored and/or bending lines, wherein the at least one line is defined at least in sections by water and/or by at least one hygroscopic substance applied to the base material. The invention further relates to a method for producing a packaging item from a blank of this type, and to a corresponding packaging item for storing goods.

A method and device for thermal activation of tube-shaped packaging sleeves made of cardboard/plastic composite material, wherein a hot gas is applied to the tube-shaped packaging sleeve by a heating device in order to produce the base or the head of the packaging. To achieve even heating for the activation of the contact surfaces with production using simple construction, wherein the energy required for the activation process is used as completely as possible for the heating of the surfaces to be activated, the heating device is placed into effective contact with the surfaces to be activated by the heating device being moved inside the tube-shaped packaging sleeves for activation. The heating device has at least one nozzle element with an outlet opening, the external shape of which nozzle element corresponds to the internal shape of the end of the tube-shaped packaging sleeve to be activated.

A method of at least partially forming a carton includes obtaining a blank comprising at least one fold line, heating an interior surface of the blank along the at least one fold line to form a heated fold line, and folding the blank about the heated fold line.

The invention relates to a method for producing packaging (18) from paper material (5), in particular paper, cardboard or paperboard, said method comprising the following steps: forming packaging (18) from a blank (19) made of paper material (5), which paper material overlaps at at least one joining site (21); positioning the at least one joining site (21) between a sonotrode (2) and an anvil (3); applying the joining site (21) with a joining force in a joining force direction (6); and making the sonotrode (2) ultrasonically vibrate in order to ultrasonically weld the paper material (5) at the joining site (21), which method is characterised in that the paper material (5) is moistened, preferably on the inner sides of the joining sites (21), before forming the packaging (18) and/or while forming the packaging (18) and/or after forming the packaging (18) and/or during the ultrasonic welding.

A method of at least partially forming a carton includes obtaining a blank comprising at least one fold line, heating an interior surface of the blank along the at least one fold line to form a heated fold line, and folding the blank about the heated fold line.

A system for automatically forming packaging boxes comprises a folding station comprising four folding units adapted to fold panels of cardboards blanks to form substantially cuboid boxes or lids or combinations of a box and a lid, some of said panels in the folded state forming pairs of two panels running substantially parallel to each other in a processing direction, in which the blanks are transported through the system, and orthogonal to a width direction of the blanks, which is the orthogonal direction to the processing direction in the plane of the blanks, one or more glue application units adapted to put glue on at least one panel of each of said pairs of two panels, a feeding conveyor to convey a cardboard blank into the folding station, a curing station adapted to take over the boxes or lids or combinations of a box and a lid folded in the forming station from the folding station, said curing station comprising holding structure to form-fittingly hold said pairs of panels and to guide the boxes or lids or combinations of a box and a lid through the curing station.

A bottle forming unit and method for dry-forming a cellulose bottle from an air-formed cellulose blank structure in a bottle forming unit. The dry-formed cellulose bottle comprises a neck portion, a closed bottom portion, and a mid-portion arranged between the closed bottom portion and the neck portion. The mid-portion is arranged in fluid communication with the neck portion. The dry-formed cellulose blank structure is shaped into a shaped cellulose blank structure, where the shaped cellulose blank structure has a tube-like configuration with an inner surface and an outer surface. A first section of the shaped cellulose blank structure is fed to a first forming mould and a semi-closed bottom portion of the cellulose bottle is formed from the first section in the first forming mould, simultaneously with forming the neck portion of a directly preceding cellulose bottle from the first section in the first forming mould. A following second section of the shaped cellulose blank structure is fed to the first forming mould and the neck portion of the cellulose bottle is formed from the second section in the first forming mould, simultaneously with forming a semi-closed bottom portion of a directly following cellulose bottle from the second section in the first forming mould.
