Description

Device and method for reshaping the gable surfaces of

Packaging with a sloping gable

The invention relates to a device for reshaping the gable surfaces of packagings with an inclined gable, comprising: a conveyor device with cells attached to it for receiving the packagings and for transporting them

Packaging along a transport direction, at least one gable butterfly for folding a fin seam in the gable area of the packaging, and at least two ear butterflies for folding ears in the gable area of the packaging, both the gable butterfly and the ear butterfly being movably mounted relative to the conveyor device and the packaging transported with it .

The invention also relates to a method for reshaping the gable surfaces of packaging with sloping gables, comprising the following steps: a) providing packaging with sloping gables, b) folding the fin seam in the gable area of the packaging by a gable butterfly, c) folding the ears in the gable area the packaging by two ear butterflies, and d) reshaping the fin seam with a molding tool.

Packaging can be made in different ways and from the most varied

Materials are made. A widespread production option is to use the packaging material to produce a blank that usually has fold lines (also known as “crease lines”), from which, by folding and further steps, first a package jacket and finally a package is created. This variant has the advantage, among other things, that the blanks are very flat and can therefore be stacked to save space. In this way, the blanks or packaging jackets can be produced at a different location than the folding and filling of the packaging jackets. Composite materials are often used as the material, for example a composite of several thin layers made of paper, cardboard, plastic or metal. Find such packaging

particularly widespread in the food industry.

Packagings that are made from blanks are known, for example, from WO 2009/141389 A2 and DE 38 35 390 A1. These packagings predominantly have gable surfaces that rise towards the center at an identical angle on both sides and are thus symmetrically shaped. The fin seam therefore forms the highest point on the packaging - at least before it is folded down.

A challenge in the production of such packaging is to create protruding areas such as seams or "ears" on the packaging. In the case of rectangular packaging, this is still quite easy; a machine for this is known, for example, from EP 0 061 663 A2.

Packagings with an asymmetrical - i.e. generally inclined - gable can also be produced from blanks. Such packaging is known, for example, from WO 2009/030910 A2 and from EP 2 468 641 B1. With this type of packaging, the creation of protruding areas is particularly difficult, since in such inclined gable packaging it is often not the fin seam but the rear edge of the gable that forms the highest point of the packaging. This makes the fin seam more difficult to access for tools.

In particular, the fin seam in packaging of this type cannot be created by a stationary tool that the packaging is guided past. An apparatus and method for forming the gable surfaces of such

Inclined gable packaging is known, for example, from DE 10 2016 109 980 A1.

Although the device described in DE 10 2016 109 980 A1 and the method described there provide good results, it can happen that the shape of the gable bulges outward again after it has been formed. In particular, it is occasionally observed that the gable seam or fin seam either not is completely applied to the gable or moves out of the applied position again. This can be due, for example, to the internal pressure of the packaging or a consequence of the ears being pressed against the side surfaces of the packaging. An uneven gable surface is not only objectionable visually, but also makes the subsequent application of further elements more difficult, for example pouring elements with screw caps.

Against this background, the invention is based on the object of maintaining and / or correcting the shape of the gable in packaging with an inclined gable.

This object is achieved in a device according to the preamble of claim 1 by at least one molding tool for reshaping the fin seam in the gable area of the packaging, the molding tool being relative to the

Conveyor and the packaging thus transported is movably mounted.

The device is a device for reshaping the gable surfaces of packagings with a sloping gable, in particular with a continuously sloping gable. In particular, the fin seam in the gable area of the packaging is (post-) shaped, with post-shaping a shaping of the previous one

called reshaped, in particular folded areas. In addition, the entire gable surface is (re) formed, for example to make certain folding edges

stabilize. The packaging is preferably a packaging for food which is made from a composite material. The

Composite material can have several thin layers of paper, cardboard, plastic or metal. The device initially comprises a conveyor device with cells attached to it for receiving the packaging and for transporting the

Packaging along a transport direction. A conveying device (for example a conveyor belt, a conveyor belt or a conveyor chain) can transmit high tensile forces that allow a large number of

To transport packing sleeves at constant intervals from one another. The cells serve to accommodate the packing sleeves. The packing shells can be held in the cells by a form-fitting connection or by a force-fitting connection. The conveyor is preferably arranged in a horizontal plane. The device also comprises at least one gable butterfly for folding a fin seam in the gable area of the packaging.

The gable butterfly is preferably arranged centrally above the conveyor device and the packaging transported on it. In addition, the device comprises at least two ear butterflies for folding ears in the gable area of the

Packagings. Preferably the two ear butterflies are above the

Conveyor and the packaging transported on it arranged on both sides next to the gable butterfly. In the device it is provided that both the gable butterfly and the ear butterfly are movably mounted relative to the conveying device and the packaging transported with it.

A device according to the invention is characterized by at least one

Forming tool for reshaping the fin seam in the gable area of the

Packaging, wherein the molding tool is movably mounted relative to the conveyor device and the packaging transported therewith. In addition to reshaping the fin seam, the molding tool is also used to reshape the gable surface. A processing station with such a molding tool can also be used as

"Post-printing station" or "Post-forming station" are designated. In other words, the molding tool - like the gable butterfly and the ear butterfly - should be mounted rotatable, pivotable, displaceable or movable in some other way. This constructive measure makes it possible for the relative movement between the molding tool and the packaging, which is required for post-forming, to be achieved by moving the molding tool and not by moving the packaging. As a result, the packaging does not need to be moved during the shaping or post-shaping process, so that the conveyor device can come to a standstill. Intermittent, cyclical operation of the conveying device is therefore possible. Shaping with the packaging at a standstill has the advantage that the packaging can be filled particularly easily, since the filling device does not needs to be moved. Another advantage is that movably mounted molding tools can also be used to form packagings in which it is not the fin seam but the rear edge of the gable that forms the highest point of the packagings.

According to one embodiment of the device, it is provided that the molding tool for reshaping the fin seam has at least two-dimensional mobility. This can be achieved, for example, in that the molding tool is movably (in particular rotatably) mounted in a plane, in particular in a plane which is formed by the transport direction and the vertical direction of the packaging. The molding tool should therefore not only be able to be displaced linearly, but rather have at least a two-dimensional mobility.

Carry out rotational movements or a combination of both (superposition of translational and rotational movements). The plane of movement of the molding tool is preferably determined by the transport direction and the vertical direction of the

Packaging formed.

Another embodiment of the device is characterized by a cross member which is arranged above the cells and extends along a transverse direction running transversely to the transport direction. The use of a traverse has the advantage that a traverse can extend over several parallel rows or lanes of packaging to be transported, so that several lanes of packaging can be processed at the same time when a corresponding number of tools (e.g. molding tools) are attached to the traverse can. Several traverses can be provided, for example a first traverse for mounting the gable leaf and a second crossbar for mounting the (post) forming tools.

For this embodiment, it is further proposed that the cross member be movably supported relative to the conveyor device and the packaging transported with it is. Movable mounting of the traverse offers various advantages. One advantage is that the molding tools can be rigidly connected to the crossbeam and can thus be mounted immovably relative to the crossbeam. This is because the molding tools remain movable relative to the conveying device and the packaging transported with it, even with a rigid connection to the traverse due to the mobility of the traverse. Another advantage of a movable mounting of the traverse is that the traverse is on different

Packaging sizes can be adjusted. In the case of a "format change", the crossbeam does not have to be exchanged; instead, for example, the height of the traverse can be adjusted. The traverse is preferably mounted movably in the vertical direction - that is, in the vertical direction - relative to the conveying device and the packaging transported with it.

With regard to the traverse, it can be provided in a further embodiment of the device that at least two, in particular at least four

Forming tools for reshaping the fin seam in the gable area of the

Packagings are provided, with all of the molding tools being mounted on the traverse next to one another in the transverse direction. This means that several packages can be processed at the same time. For example, several conveyor belts running in parallel can be provided. A molding tool is preferably assigned to each row of packages to be processed.

According to a further embodiment of the device it is provided that the

Gable butterfly and the mold and / or their trusses through a

mechanical connection are coupled to each other and have a common drive. A mechanical coupling of the tools (gable butterfly,

A synchronous movement of these tools can be achieved. This enables all tools to use the same drive. The mechanical coupling can take place via the tools themselves or via the crossbars on which the tools are stored. According to a further embodiment of the device it is provided that the

Molding tool comprises a mold carrier and a support. A multi-part construction of the molding tool enables easier adaptation to differently shaped packaging by exchanging the supports, the profiles of which are adapted to different gable surfaces. The mold carrier is preferably made of metal and is used to carry different supports. The replaceable pad is preferably made of silicone, plastic, rubber or another elastic or stretchable material or at least coated with it (e.g. metal core with coating).

In a further embodiment of the device it is provided that the cells are spaced apart from one another and that the molding tool is at least twice the cell spacing from the gable butterfly and / or from the ear butterflies. By spacing the tools apart, it is achieved that the reshaping by the molding tool does not immediately follow the folding of the gable and the ears, but takes place at the earliest two “cycles” afterwards. This has the advantage that the temperature of the packaging in the gable area has already cooled down somewhat and the ears are firmly attached. Too early (re) shaping would have the disadvantage that the gluing process of the ears is not yet completely finished, which could result in the ears being removed from the

Packaging could solve. In addition, an arrangement of the (post) forming tools directly behind the gable forming station is difficult to implement because of the space requirements.

The object described above is also achieved by a method for

Reshaping of the gable surfaces of packaging with sloping gables, comprising the following steps: a) Providing packaging with sloping gables, b) Folding the fin seam in the gable area of the packaging using a gable butterfly, c)

Folding the ears in the gable area of the packaging using two ear butterflies, and d) reshaping the fin seam using a molding tool. The method is characterized in that in step d) the molding tool relative to the Conveyor and the packaging transported with it is moved. The packaging can be provided in particular by a conveyor device in the form of a conveyor belt or a conveyor belt or a

Transport chain with attached cells for receiving the packaging. The conveyor belt or the conveyor belt or the conveyor chain is preferably arranged in a horizontal plane. As has already been described in connection with the device, the relative movement between the molding tools and the packaging which is required for the molding is to be achieved by moving the molding tools and not by moving the packaging. As a result, the packaging does not need to be moved during the shaping process, which enables intermittent, cyclical operation of the conveyor device. Shaping with the packaging at a standstill has the advantage that the filling can also take place with the packaging at a standstill and also allows packaging to be processed in which the rear edge of the gable is not the highest point of the packaging, but not the fin seam. The method is preferably carried out with a device according to one of Claims 1 to 8.

According to one embodiment of the method, it is provided that the packaging is moved by a conveyor device with cells attached to it. As has already been described above in connection with the device, a conveyor device (for example a conveyor belt, a

Conveyor belt or a conveyor chain) high tensile forces are transmitted, which allow a large number of pack sleeves to be transported at constant distances from one another. The cells are used to hold the packing sleeves. The

Packing jackets can be held in the cells by a form-fitting connection or by a force-fitting connection. The

The conveyor is preferably arranged in a horizontal plane.

According to a further development of the method, it is provided that the packaging is moved intermittently. An intermittent, i.e. cyclical operation has that The advantage is that the packaging stands still for a short time and can be processed more precisely in this phase. Another advantage is that the tools that process the packaging do not need to be moved along with the packaging.

A further embodiment of the method provides that the packagings stand still during step b), during step c) and during step d). Steps b) and c) serve to fold the fin seam and put on the protruding ears, while step d) serves to reshape the gable surface, in particular the fin seam. These steps should be carried out as precisely and quickly as possible without damaging or deforming the packaging. These requirements can be met more easily with stationary packaging than with continuously moving packaging.

According to a further development of the method, it is provided that in step d) the gable surfaces of at least two, in particular at least four, packs are simultaneously reshaped. This further development ensures that several packagings can be processed at the same time. For this purpose, for example, several parallel conveyor belts can be provided.

A molding tool is preferably assigned to each row of packages to be processed.

According to a further embodiment of the method, it is finally provided that step d) is carried out at a location that is at least twice

Cell spacing (A) to the location at which step b) and / or step c) is carried out. By maintaining a minimum distance between the

The processing locations ensure that the reshaping by the forming tool does not take place too close behind the folds of the gable and the ears, but only takes place two “cycles” after or even later. This has the advantage that the temperature of the packaging in the gable area has already cooled down somewhat and the ears are firmly attached. Too early (re) shaping would have the The disadvantage is that the ears have not yet been fully glued, which could result in the ears becoming detached from the packaging. In addition, an arrangement of the (post) forming tools directly behind the gable forming station is difficult to implement because of the space requirements.

In the following, the invention is merely a preferred one

1A shows a blank 1 for folding a packaging jacket. The blank 1 can comprise several layers of different materials, for example paper, cardboard, plastic or metal, in particular aluminum. The blank 1 has several fold lines 2, which are intended to facilitate the folding of the blank 1 and divide the blank 1 into several areas. The blank 1 can be divided into a jacket surface 3, base surfaces 4, gable surfaces 5 and a sealing surface 6. The bottom surfaces 4 and the gable surfaces 5 each include rectangular surfaces 7, 7B, 7G and triangular surfaces 8. The gable surfaces 5 also include a centrally arranged gable main surface 9. The lateral surface 3 extends - apart from the

Sealing surface 6 - over the entire width of the blank 1. A pack casing can be formed from the blank 1 by folding the blank 1 in such a way that the sealing surface 6 is connected, in particular welded, to the opposite end of the casing surface 3.

The blank 1 shown in FIG. 1A has two in the area of the lateral surface 3

Dummy fold lines 10. The two dummy fold lines 10 run parallel to one another and run through a point of contact SB of three adjacent ones Triangular surfaces 8 of the bottom surface 4 and through a point of contact SG of three adjacent triangular surfaces 8 of the gable surfaces 5. By the dummy fold lines 10, the lateral surface 3 is divided into an inner sub-area 3A and two outer ones

Subareas 3B divided. The inner sub-area 3A lies between the two

Bill fold lines 10 and the outer partial areas 3B lie outside the two bill fold lines 10.

While the bottom surface 4 has a length L4 which is constant over the entire width of the blank 1, the length of the gable surface 5 assumes different values. Adjacent to the outer partial areas 3B of the lateral surface 3, the

Gable surface 5 has a reduced length L5 _mm . Adjacent to the inner

Subarea 3A of the lateral surface 3 (that is to say in the area of the main gable surface 9), on the other hand, the gable surface 5 has an increased length L5 _max . This design means that the inner sub-area 3A has a lower height than the outer

Sub-areas 3B. For the pack to be produced, this results in an inclined, forward sloping gable area.

The rectangular areas 7B in the bottom area of the blank are rectangular. The two outer rectangular surfaces 7G in the gable area of the blank are also rectangular. The middle gable main surface 9, however, is not exactly rectangular; Instead, it is formed with an at least partially convex front edge 11. In the upper corner areas of the main gable surface 9, two curved embossed lines 12 can be seen, which give the main gable surface 9 a shape reminiscent of an ellipse. A circular line of weakness S is shown centrally within the gable top surface 9. This is preferably a circular recess in the carrier material, which is covered with the remaining plastic and possibly Al layers of the composite material, a so-called “overcoated hole”. Its diameter can match the size of the cutting element there

be adapted to be attached pouring element or made relatively small to allow the penetration of a drinking straw. The bottom surfaces 4 have two corner points E4 and the gable surfaces 5 have two corner points E5. The corner points E4, E5 represent corner points of the packaging to be produced from the blank 1. Each corner point E4 of a floor area 4 is assigned a corresponding corner point E5 of a gable surface 5, which is the corner point E5 that is above this corner point when the packaging is standing E4 is arranged. A fold line 2 'runs through two corresponding corner points E4, E5, each of which serves to form a rear (vertically running) edge of the packaging to be produced. However, in the case of the blank 1 shown in FIG

Package jacket and the packaging produced from it - only two continuous folding lines 2 'are present. Between the other corner points of the bottom surfaces 4 and the corresponding corner points of the gable surfaces 5 - that is, on the other hand, no fold lines are provided on the front lateral surface 3A.

FIG. 1B shows a package jacket 13, which is formed from the blank 1 shown in FIG. 1A, in the folded flat state in a front view. Those already in

Areas of the packing jacket described in connection with FIG. 1A are provided with corresponding reference symbols in FIG. 1B. The package jacket 13 was created from the blank 1 in two steps: First, the blank 1 is folded along the two dummy fold lines 10. Subsequently, the two partial areas 3B (left) and 3B (right) of the jacket surface 3 in the area of the sealing surface 6

connected to one another, in particular welded, whereby a longitudinal seam 14 (hidden in FIG. 1B) is produced. The packing jacket 1 thus has a circumferential structure that is closed in the circumferential direction and has an opening in the region of the

Floor surfaces 4 and with an opening in the area of the gable surfaces 5. ln the

The front view shows the inner sub-area 3A of the lateral surface 3, which is delimited on both sides by the dummy fold lines 10. The remaining sub-areas 3B of the

The outer surface 3 are covered on the rear side of the packing jacket 13 and therefore in FIG. 1B. In FIG. 1C, the package jacket 13 from FIG. 1B is shown in a rear view. The areas of the already described in connection with FIGS. 1A and 1B

Packing jacket are provided with corresponding reference numerals in Fig. IC. In the rear view, the two outer partial areas 3B of the lateral surface 3 are visible, which are connected to one another by the longitudinal seam 14 and which are delimited on both sides by the dummy fold lines 10. The front sub-area 3A of the jacket surface 3 is covered on the front side of the packaging jacket 13 and therefore in FIG. IC.

FIG. ID shows the package jacket 13 from FIG. 1B and FIG. 1C in the unfolded state. The regions of the packaging jacket already described in connection with FIGS. 1A to 1C are provided with corresponding reference symbols in FIG. ID. The unfolded state is achieved by folding back the package jacket 13 along the dummy fold lines 10 running through the jacket surface 3. The

Refolding takes place by about 180 °. The folding back along the note fold lines 10 has the consequence that the two partial areas 3A, 3B of the lateral surface 3 adjoining the note fold line 10 no longer lie flat on top of one another, but are arranged in the same plane. The package jacket 13 is therefore only folded in its flat state (FIG. 1B, FIG. 1C) along the note folding lines 10; In the unfolded state (FIG. ID), however, the package jacket 13 (as well as the package to be produced therefrom) is no longer folded along the dummy fold lines 10. Hence the name "Schein" - fold lines 10.

In FIG. IE, the package jacket from FIGS. 1B to ID is shown with a closed bottom. The areas of the package jacket already described in connection with FIGS. 1A to ID are provided with corresponding reference symbols in FIG. ID. The bottom can be closed, for example, while the unfolded pack jacket 13 is pushed onto a mandrel of a mandrel wheel. To close the bottom, for example, the bottom

Triangular areas 8 folded inwards before the lower rectangular areas 7B are folded inwards. The folded surfaces are then welded by the action of pressure and temperature. Fig. 1F shows the pack jacket from Fig. 1B to Fig. IE with pre-folded gable surfaces. The regions of the packing jacket already described in connection with FIGS. 1A to IE are provided with corresponding reference symbols in FIG. 1F. The pre-folded state denotes a state in which the fold lines 2 in the region of the gable surfaces 5 have been pre-folded. The rectangular area 7G and the main gable area 9 are folded inward during the pre-folding and later form the gable of the packaging. The triangular surfaces 8, however, are folded outwards during the pre-folding and form protruding areas made of excess material, which are also referred to as “ears” 15 and later

Manufacturing step - for example by gluing - to the outer surface 3 of the

Packaging to be applied.

Fig. IG shows a package 16 which is made up of that shown in Figs. 1B to 1F

Packing jacket 13 is made, with an unshaped gable. Those already in

Areas of the packaging described in connection with FIGS. 1A to 1F are provided with corresponding reference symbols in FIG. The packaging 16 is shown after welding, that is to say in the filled and closed state. Due to the increased length L5 _{max of} the gable main surface 9 in its area adjoining the inner sub-area 3A of the lateral surface 3 and the reduced length L5 _{mm of} the gable surface 5 in its area adjacent to the outer sub-areas 3B of the

The area adjacent to the jacket surface 3 creates an enlarged main gable surface 9. On this main gable surface 9, the packaging 16 can be provided with a pouring element which extends almost to the front edge 11 which is curved forwards. In the area of the gable surfaces 5, a fin seam 17 is created after the closure. In FIG. 1G, the ears 15 and the fin seam 17 protrude. The ears 15 are placed in a later manufacturing step, for example by gluing processes, whereby the fin seam 17 also automatically remains in a flat position. In FIG. 1H, the packaging 16 from FIG. 1G is shown with a shaped gable, in particular with attached ears 15. The already in connection with Fig. 1A to Fig. 2G described areas of the packaging are in Fig. 1H with corresponding

Provided with reference numerals. In addition to the ears 15, the fin seam 17 is also applied to the packaging 16. The upper ears 15 arranged in the region of the gable surface 5 are folded down and laid flat against the lateral surface 3.

The ears 15 are preferably glued or welded to the lateral surface 3.

The packaging 16 shown in FIG. 1H has no folding edges in the area of the front lateral surface 3A. The front of the packaging curved forwards can be clearly seen in the horizontal section through plane E of the packaging shown on the right. The straight fold lines 2 'on the rear edges of the pack run from the lower corner points E4 to the upper corner points E5.

FIG. 2 shows a system 18 for filling and closing packages in a side view. The system 18 comprises a revolving conveyor device 19 with cells 20 attached to it for receiving pack jackets 13. The pack jackets 13 are pushed into the cells 20 in the state shown in FIG. 1E, that is, with the bottom surfaces already closed. The system 18 comprises a device 21 for pre-folding the gable surfaces, a device 22 for filling the

Packing jackets, a device 23 for closing the pack jackets, a device 24 for shaping the gables of the packs 16 and a device 25 for reshaping the gables of the packs 16. In the device 21 for

Pre-folding the gable surfaces are the gable surfaces in the previously

In the device 22 for filling the packaging sleeves, the packaging sleeves 13 are filled with contents. Then the pack jackets 13 are closed in the device 23 for closing the pack jackets, taking the shape shown in FIG. After closing, the

Packing jackets 13 are referred to as packagings 16. After that, the

Packages 16 processed in the device 24 for forming the gables of the packages in such a way that they assume the shape shown in FIG. 1H. The processing includes folding the fin seam 17 and putting on the ears 15.

The packaging 16 is then processed in the device 25 in such a way that that the gables of the packaging 16 - especially those arranged there

Fin seams 17 - can be reshaped to bring them into the desired shape. Subsequently, the packs 16 are removed from the cells 20 of the conveyor device 19. As can be seen - only schematically - in FIG. 2, it can be provided that the device 24 and the device 25 have a mechanical connection 26. In this way, the device 24 and the device 25 can be mechanically coupled to one another and driven by the same drive. FIG. 3 shows an enlarged section of the system 18 for filling and closing packages from FIG. The areas of the system 18 already described in connection with FIG. 2 are shown correspondingly in FIG

Provided with reference numerals. The enlarged section shows in particular that area of the system 18 in which the device 24 and the device 25 are arranged. The packaging 16 is transported by the conveyor device 19 at a distance A from one another along a transport direction T, the distance A denoting the distance between two adjacent cells 20 in the transport direction T.

The device 24 for forming the gables of the packaging 16 has a

Gable folder 27 for folding the fin seam 17 in the gable area of the packaging 16. The device 24 also has two ear flaps 28A, 28B for folding the ears 15 in the gable area of the packaging 16. Furthermore, the device 24 comprises a traverse TI on which the gable butterfly 27 are mounted. The traverse TI is movably mounted relative to the conveying device 19, which is achieved in the embodiment shown in FIG. 3 in that the traverse TI is fixedly mounted on a lever arm H4, which is rotatably connected to a further lever arm H3, which is connected to a Fixed axis of rotation D3 can be rotated. A rotation of the lever arm H3 about the stationary axis of rotation D3 therefore results in a movement of the cross member TI and the gable folder 27. The structure and functioning of this - too Device 24 called “gable forming station” are described, for example, in DE 10 2016 109 980 A1.

The device 25 for reshaping the gables of the packaging 16 has a molding tool 29 for this purpose. Furthermore, the device 25 comprises a cross member T2 on which the molding tools 29 are mounted. The traverse T2 is relative to the

Conveyor 19 movably mounted, which is the case with the one shown in FIG

Embodiment is realized by a lever arm H2, which can be rotated about a fixed axis of rotation D2. The device 24 (in particular its gable leaf 27) and the device 25 are driven via a common drive 30, which can be designed as an electric motor, for example. Together with the

Device 25 and its forming tools 29 are intended, in particular, to drive the gable leaf butterfly 27 of the device 24, while the ear butterfly 28A, 28B of the device 24 preferably have a separate drive. The drive 30 can rotate about a fixed axis of rotation D3 and transmit its drive power to one of the two devices 24, 25 via lever arms H3, H4 connected to one another in a rotatable manner (in FIG. 3: transmission of the drive power to the traverse TI of the device 24). The mechanical connection 26 connects the lever arm HI of the device 24 to the lever arm H2 of the device 25 and thus ensures that the drive power of the drive 30 is transmitted to both devices 24, 25, so that both devices 24, 25 - partially or completely - Can be driven by the same drive 30. For this purpose, the mechanical connection 26 is designed like a coupling rod which is rotatably connected at both ends to the lever arms H1, H2 to be connected. 4A shows a device 25 according to the invention for reshaping the

Gable surfaces of packaging 16 with an inclined gable shown in an open position in a side view. FIG. 4B shows the device 25 from FIG. 4A in one

Front view. The device 25 comprises a forming tool 29 which is attached to a cross member T2 which can be pivoted about an axis of rotation D2. The molding tool 29 is therefore relative to the conveyor 19 and the therewith transported packaging 16 movably mounted. The molding tool 29 comprises a mold carrier 31 and a support 32 which has a recess 33. The movable mounting of the molding tool 29 has the advantage that the gable surface and in particular the fin seam 17 can be easily reached, although it can be arranged lower than the highest edge of the packaging 16. The molding tool 29 is mounted such that it moves in one plane which is formed by the longitudinal direction corresponding to the transport direction of the packaging 16 (shown as the X direction in FIGS. 4A to 4D) and the vertical direction (shown as the Y direction in FIGS. 4A to 4D). The molding tool 29 accordingly has two-dimensional mobility. The - open - position of the device shown in FIGS. 4A and 4B is characterized in that the molding tool 29 does not touch the packaging 16 and that the packaging 16 can be moved through under the molding tool 29 in the transport direction T without collision. 4C shows a device 25 according to the invention for reshaping the

Gable surfaces of packaging 16 shown with sloping gable in a closed position in a side view. FIG. 4D shows the device 25 from FIG. 4C in a front view. The already in connection with FIGS. 4A and 4B

areas of the device described are shown in FIGS. 4C and 4D with

corresponding reference numerals. The - closed - position of the device shown in FIGS. 4C and 4D is characterized in that the

Forming tool 29 was pivoted downwards by rotating the cross member T2 about the axis of rotation D2. The molding tool 29 has the fin seam 17 placed against the gable surface of the packaging 16. In FIG. 4D, the purpose of the recess 33 provided in the support 32 of the molding tool 29 can be seen: The recess 33 serves to hold the packaging 16 in the area of a

overcoated hole (“OCH” = overcoated hole) is not touched in order to damage the packaging 16 in this particularly sensitive area neither mechanically nor thermally, so that the subsequent application of a

Pouring element with screw cap in this area of the packaging 16 is simplified. List of reference symbols:
