The invention relates to a method for forming package bodies open at one end from package sleeves open at both ends for the manufacture of filled packages. In order to allow packages with a cross section which is neither square nor rectangular to be formed more simply and reliably, the package sleeves are kept ready for further processing in a stack, folded flat along at least two folded edges running in the longitudinal direction of the package sleeve, the flat-folded package sleeves are transferred in succession from the stack to a forming station, the package sleeves are unfolded in a forming station and the unfolded package sleeves are, in the forming station, pushed onto a mandrel in order to close, in particular seal, a longitudinal end of the package sleeve.

The invention relates to a method comprising, as method steps, a) providing a sheetlike composite comprising, as mutually superposed layers of a layer sequence, from an inner face of the sheet like composite to an outer face of the sheetlike composite i) an inner polymer layer, ii) a barrier layer, and iii) a carrier layer, wherein the sheetlike composite comprises a first longitudinal edge and a further longitudinal edge, wherein the first longitudinal edge lies opposite the further longitudinal edge, wherein the sheetlike composite includes, in the following sequence in the direction from the first longitudinal edge to the further longitudinal edge: i.a first longitudinal g crease, ii.a second longitudinal crease, iii.a third longitudinal crease, and iv.a fourth longitudinal crease; b) producing a first longitudinal fold characterized by a first internal angle along the first longitudinal crease and a third longitudinal fold characterized by a third internal angle along the third longitudinal crease; c) producing a second longitudinal fold characterized by a second internal angle along the second longitudinal crease and a fourth longitudinal fold characterized by a fourth internal angle along the fourth longitudinal crease; and d) contacting and joining the first longitudinal edge to the further longitudinal edge thereby obtaining a longitudinal seam. The invention further relates to a container precursor and to a closed container, each obtainable by the method, to an apparatus and to a use of the apparatus.

A method and a machine for realizing containers, including at least steps of impressing a shape in relief on a sheet of deformable material, enveloping the sheet about itself and reciprocally joining lateral flaps thereof in order to form a tubular blank, and closing a bottom end of the tubular blank.

A device for shaping the gable surfaces of packages with a slanted gable is shown and described, including: a conveyor system with cells fixed to it to receive the packages, at least one gable folder to fold a fin seam in the gable region of the packages and at least two ear folders to fold ears in the gable region of the packages. In order to enable rapid and reliable shaping of the gable even in packages with slanted gables, it is proposed that both the gable folder and the ear folders be mounted movably relative to the conveyor system and the packages to be transported therewith. A method for shaping the gable surfaces of packages with a slanted gable is also shown and described.

Described and depicted is a method for forming package bodies open on one side from package sleeves open on both sides for the manufacture of filled packages, in which the package sleeves are folded flat and held ready for further processing in a stack around at least two folding edges running in the longitudinal direction of the package sleeves, in which the flat-folded package sleeves are transferred successively from the stack to a forming station, in which the package sleeves are unfolded in the forming station, in which the package sleeves are pulled in the forming station through a channel coming into contact with the two opposite folding edges of the package sleeve and tapering transversely to the package sleeve and/or the package sleeves are positioned in the forming station between at least two form halves of a form and unfolded by closing the form, and in which the unfolded package sleeves are slid from the forming station onto a mandrel for closing, in particular sealing, a longitudinal end of the package sleeve.

A device is depicted and described for the single-sided closure of packaging sleeves for the production of composite packages, in particular carton/plastic-composite packages, by forming by means of a mandrel wheel with a plurality of mandrels arranged distributed uniformly over the circumference and directed radially outwards, which pass successively through several processing stations in the circumferential direction of the mandrel wheel, wherein each mandrel has a head on its free end, on which the folding sections to be closed of the packaging sleeve slid onto the mandrel are folded and sealed in the closed position, and wherein the head of the mandrel is designed to be variable in its outer dimensions. In order to reliably ensure a reliable and in particular a pocket-free sealing of the end area of the packaging sleeve on the mandrel, it is provided that at least two corner segments of the head are variable in their position, that the mandrel in its interior has at least one axially movable tappet for the adjustment of the head geometry and that the corner segments of the head are designed as pivot elements, which can be brought from a sealing position into a retracted position.

A laser ablation marking system for providing an image to a web of packaging material is provided. The marking system includes at least one marking device having at least one laser having a plurality of individually controlled light outputs arranged in the cross-wise direction of the web of packaging material, each light output having a power output of at least 60 W and being configured to emit light to provide laser ablation, and a controller being connected to the marking device and configured to control the light outputs based on the speed of the web of packaging material such that the emitted light will always hit the web of packaging material at the same angle.

A device for shaping closed packages is depicted and described, including: a base plate for supporting the bottom or the gable of the packages, at least two support elements for supporting the side surfaces or the front surface and the rear surface of the packages and at least two sliding elements for shaping the side surfaces or the front surface and the rear surface of the packages wherein the support elements and the sliding elements include at least one shaped surface on their side assigned to the package. In order to also enable a precise shaping of the packages even in the case of closed packages with complex geometry, it is proposed for at least one of the shaped surfaces to be curved at least in sections. A method for shaping closed packages is also depicted and described.

A filling machine for filling packaging containers made of cardboard composite material with products, in particular liquid foods, includes a gripper that removes a packaging jacket from a magazine only partially erected in the manner of a parallelogram by a guide and at least one of two retaining elements for accommodating an outer fold edge of the partially erected packaging jacket can be move back and forth between an initial position and an end position. The cross-section of the packaging jacket accommodated by the two retaining elements is rectangular in the end position of the movable retaining element.

Provided are a method and an apparatus for sterilizing a sleeve that can shorten a sterilization process for a paper container sleeve and ensure a sterilization effect.

In a method for sterilizing a sleeve in an aseptic filling system that molds the sleeve into a paper container having a bottomed tubular shape by closing surfaces of an open end part of the sleeve and performs sterilization, filling and sealing of the paper container, the sleeve being a tubular body having walls formed by laminating at least paper, in a state where the sleeve stands in a columnar shape, heated air containing a sterilizer is blasted to an inner surface of the sleeve that is to form a bottom part of the paper container to perform sterilization of the inner surface of the bottom part and heating for the closing at the same time.
