Description

PAPER PACKAGING MATERIAL SUPPLY

The present invention relates to a paper packaging material supply for a packaging machine. Packaging machines generally use paper, especially recycled paper, as the packaging raw material. A paper web in zigzag folds (leporello folds) is provided as a suitable paper supply. The zig-zag folding offers a cuboid-like storage stack structure that is particularly space-saving and gentle to store and transport.

A generic paper packaging material supply is known, for example, from the utility model DE 20 2014 008 810.1 of the applicant. The paper packaging material supply comprises a transport pallet and several zigzag-folded paper web stacks which are arranged in a row on the pallet and connected to one another. To connect two paper strip stacks arranged one behind the other, an upper folded end sheet is pulled down to the transport pallet and there coupled with an underlying folded end sheet of the paper web stack located downstream, or vice versa. The paper packaging material supply formed in this way enjoys great popularity in principle, since a storage space-saving and transport space-saving storage of paper packaging material that is as large as possible is made possible. Nevertheless, it has been shown that there is still a need for paper web supplies with larger linear meters.

One object of the present invention is to improve the disadvantages of the prior art, in particular to further develop a paper packaging material supply in such a way that packaging delays are further reduced.

The object is achieved by the subject matter of claims 1 and 7, respectively. Thereafter, a paper packaging material supply is provided which has a base support, such as a transport pallet. The transport pallet can be, for example, a Euro pallet or another internationally standardized pallet. In general, the base carrier is used to be able to transport the paper packaging material to and from as a unit. The base support can, for example, have dimensions of 800 mm x 1200 mm (width x length). The paper packaging material supply can, for example, be set up in the vicinity of a packaging material processing machine and / or can be used to feed packaging material processing machines.

Furthermore, the paper packaging material supply comprises at least two zigzag-folded paper web stacks. However, more than two, preferably three, four, five or more zigzag-folded paper web stacks can also be provided. The paper web stacks are produced, for example, from a web-shaped paper material and are provided and / or pre-assembled in zigzag folds, in particular in a fan-fold arrangement. The paper of the paper web stack can comprise recycled paper, in particular waste paper and / or 100% recyclable paper, which can be produced without chemical ingredients. Recycled paper is in particular paper materials with a low proportion (less than 50%) of fresh fiber-containing paper material. For example, paper materials that contain 70% to 100% waste paper are used. The recycled paper in the context of this invention can be paper material which can have a tensile strength index in the machine direction of at most 90 Nm / g, preferably a tensile strength of 15 Nm / g to 60 Nm / g, and a tensile strength index transverse to the machine direction of at most 60 Nm / g may have, preferably a tensile strength of 5 Nm / g to 40 Nm / g. A standard DIN EN ISO 1924-2 or DIN EN ISO 1924-3 can be used to determine the tensile strength or the tensile strength index. Additionally or alternatively, a recycled paper property or waste paper property can be characterized by the so-called burst resistance. A material in this sense is recycled paper with a bursting index of at most 3.0 kPa * m ^A 2 / g, preferably with a bursting index of 0.8 kPa * m ^A 2 / g to 2.5 kPa * m ^A 2 / g. The DIN EN ISO 2758 standard is used to determine the bursting index. Furthermore, the paper has a mass per unit area of in particular 40 g / m ² to a maximum of 140 g / m ² . The paper stacks are arranged next to one another on the base support and connected to one another transversely to their unfolding and / or consumption conveying direction. The unfolding and / or consumption conveying direction is to be understood as a direction oriented in the longitudinal direction of the paper web, in which, on the one hand, the zigzag-folded paper web stack can be unfolded and pulled off. A conveying direction can be defined by unfolding and pulling off the paper web. For example, the two paper web stacks are arranged on the base carrier in such a way that their unfolding and consumption conveying directions are oriented essentially parallel to one another. The paper web stacks can be set up in the well-known Leporello fold on the base support in the manner of a column. The paper web stacks can be arranged in such a way that a column wall of the paper web stack oriented transversely to the unfolding and / or consumption conveying direction faces a corresponding column wall of the adjacent paper web stack. By connecting paper web stacks also transversely to the unfolding and / or consumption conveying direction, the supply of paper packaging material can be increased further, so that packaging delays can be further reduced. In particular, due to the cross connection according to the invention between two paper web stacks, it is possible to also arrange paper web stacks next to one another and convey them away without interruption, as a result of which the number of running meters to be stored can be doubled.

In an exemplary development of the paper packaging material supply according to the invention, each paper web stack is placed separately loosely on the base carrier. In the case of the at least two paper web stacks arranged side by side transversely to the unfolding and / or consumption conveying direction, an upper folded end sheet of one paper web stack can serve as a support for the adjacent paper web stack, in particular serve as the bottom folded end sheet of the other paper web stack. The other stack of paper webs can be placed on the support formed by the folded end sheet and coupled to it. The coupling can be implemented, for example, by means of adhesive strips provided on the folded end sheet, optionally with protective film, which are described by way of example in WO 2002/40262 A1.

According to an exemplary alternative embodiment, a lower folded end sheet of the one paper web stack is with the upper folded end sheet of the other paper web stack coupled, whereby the coupling can be done analogously. The folded end sheets of the two paper web stacks connected to one another can be connected to one another in such a way that the zigzag sequence can be continued continuously across the paper web stack. The end edge of the upper or lower folded end sheet can be provided with an adhesive strip, preferably with a protective film which can be peeled off to activate the adhesive strip. For example, it is also possible to use a so-called cold-sealable adhesive that is activated from the outside by an external pressure force. As a result of the pressure force, the cold sealable adhesive provides an adhesive function that is activated by pressure. Each paper web stack forms an uninterrupted, essentially adhesive-free, continuous paper web, except for the adhesive strips provided on the folded end sheets for connection to the adjacent paper web stack, when the entire stack height is unfolded. In particular, the paper web stack is not created in that several bundles are coupled to one another via adhesives, but rather forms a continuous, uninterrupted paper web which is folded into a paper web stack like a fanfold and only when coupled to an adjacent paper web stack, which is in particular the same design, a Coupling is accompanied by another paper web, which is also folded like a fan-fold.

In an exemplary embodiment of the present invention, at least two rows of at least two zigzag-folded paper web stacks are arranged next to one another transversely to the unfolding and / or consumption conveying direction. For example, a total of four, six, eight, ten or 12 stacks of paper webs can be placed on the base support. In each row, the paper web stacks are arranged one behind the other in the unfolding and / or consumption conveying direction and are connected to one another. Per row, the paper web stacks can be arranged according to the paper packaging material supply according to DE 20 2014 008 810 Ui, the content of which is fully incorporated herein by reference. At least one stack of paper in one row is connected to a stack of paper in the other row. The present invention therefore enables even a base carrier on which two rows of paper web stacks are placed next to one another, ie transversely to the unfolding and consumption conveying direction, without interruption from the To promote and process grand carriers, in particular to feed them to a packaging material processing machine or packaging machine.

In a further exemplary embodiment of the paper packaging material supply according to the invention, the number of cross connections between two paper web stacks of different paper web stack rows is half or one less than the number of paper web stacks arranged on the base carrier. For example, two paper web stacks arranged next to one another at right angles to the unfolding and / or consumption conveying direction can be connected to one another. Furthermore, one of the two mentioned paper web stacks can additionally be connected to a paper web stack from the adjacent row of paper web stacks which is leading or trailing in the unfolding and / or consumption conveying direction. Schematically speaking, there is a zigzag connection of the rows of paper web stacks. The number of cross connections is one less than the number of paper web stacks arranged on the base carrier. In an alternative embodiment, the paper web stacks arranged next to one another transversely to the unfolding and / or consumption conveying direction are connected to one another, with two paper web stacks of the same paper web stack row in unfolding and / or or consumption conveying direction are interconnected. Schematically speaking, this results in a serpentine connection. The number of cross connections is half the number of paper web stacks arranged on the base carrier. According to an exemplary development, at least three paper web stacks are arranged next to one another on the base carrier and connected to one another transversely to the unfolding and / or consumption conveying direction. For example, two cross connections are formed between the respective immediately adjacent paper web stacks. Furthermore, it can be provided that three rows of at least two, in particular 3 or 4, paper web stacks arranged next to one another on the base carrier form a paper packaging material supply. For example, a total of 12 paper web stacks can be stored on the base carrier. An outer paper web stack of the two outer paper web stack rows can be connected to an outer paper web stack of the middle paper web stack row, the paper web stacks per row also being connected to one another in the unfolding and / or consumption conveying direction. When processing the Paper packaging material supply results in a zigzag direction or an S-shaped direction. A combination of these is also possible.

According to an exemplary development of the paper packaging material supply according to the invention, the paper web stacks connected to one another form at least 100 linear meters. The running meters per base support can also be at least 1000, 10,000, 20,000, 30,000 or 40,000 running meters. It was found that the running meter performance per base carrier also depends on the grammage or density of the paper web. For example, at a grammage of 70 g / m ^2, a running meter performance of 15,200 can be achieved, at a grammage of 50 g / m ² a running meter performance of 21,800 and at a grammage of 28 g / m ² a running performance of 38,000 running meters.

In a further exemplary embodiment of the paper packaging material supply according to the invention, the paper web stacks arranged next to one another and optionally two paper web stacks arranged one behind the other per paper web stack row are arranged at a distance from one another, forming a gap. In particular, all paper web stacks in a position adjacent to another paper web stack of the same row and the adjacent row form a gap. The gap can be dimensioned uniformly in height, depth and width direction. The gap space is limited by the folded edge sides of the paper web stacks, which are diametrically opposed and can have a corrugated profile because of the folded edges. The gap can ensure that the paper web stacks can stand next to one another without contact and, if necessary, one behind the other. The gap surprisingly causes the paper web stacks to be unfolded and conveyed away safely and with little paper jam. The strong air currents that occur when the paper web stacks are unfolded, which can impair the packaging process if the paper web stacks are in direct contact with one another and the gap is too narrow, can thus be avoided. In particular, the gap is at most 100 mm, in particular at most 80 mm or at most 60 mm, and preferably at least 10 mm or at least 20 mm. In a further exemplary embodiment of the present invention, the paper web stacks each have a width, measured transversely to the unfolding and / or consumption conveying direction, of 20 mm to 800 mm, in particular up to 700 mm, 600 mm, 500 mm, 400 mm, 300 mm, 200 mm , 100 mm, 50 mm or up to 30 mm, and / or a height of at least 100, in particular at least 150 mm or at least 200 mm. For example, the height of the respective paper web stacks is greater than 80 mm and, for example, less than 1000 mm. Due to the specified dimensions, the paper web stacks form compact paper packaging material supplies. For example, the paper web stacks can assume a cuboid shape, columnar shape or the like, with a stack depth of over 50 mm, in particular 100 mm or 200 mm, in particular of about 280 mm and a width of over 100 mm, in particular 200, preferably of about 380 mm, can be provided.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a paper packaging material supply is provided. The paper packaging material supply can, for example, be designed in accordance with one of the aforementioned embodiments.

The paper packaging material supply includes a base carrier, such as a transport pallet, which can be, for example, a euro pallet or another internationally standardized pallet. In general, the base carrier is used to be able to transport the packaging material to and from as a unit.

Furthermore, the paper packaging material supply comprises at least two zigzag-folded paper web stacks arranged on the base carrier. The paper web stacks can be designed and / or produced in accordance with one of the aforementioned embodiments. The longitudinal directions of the paper web stacks are oriented parallel to one another. The paper web stacks can, for example, be arranged next to one another on the base carrier transversely to their unfolding and / or consumption conveying direction.

Both paper web stacks each have an upper folded end sheet and a lower folded end sheet for placing the respective paper web stack on the base carrier. A paper web stack bridging section connects to the lower folded end sheet of the one paper web stack. the

Paper web stack bridging section protrudes from the paper web stack in the paper web longitudinal direction. Furthermore, the paper web stack bridging section is folded over along a first fold edge transversely to the longitudinal direction of the paper web and folded over again along a second fold edge arranged in the region of the further paper web stack. According to the further aspect of the present invention, the paper web stack bridging section is folded over along the second folding edge in the area of the further paper web stack such that the paper web stack connecting section extends essentially in the longitudinal direction of the paper of the further paper web stack and is connected to its upper folded end sheet. The connection and / or coupling of the paper web stack connecting section to the upper folded end sheet can be implemented, for example, by an adhesive strip preferably provided with a protective film or by a cold-sealable adhesive that can be activated by means of external pressure. The inventive folding and connection of the two zigzag-folded paper web stacks enables safe, paper-jam-free conveyance of the two paper web stacks coupled to one another, so that the connected paper web can be unfolded and processed without interruption, for example in a downstream packaging machine. Furthermore, the folding according to the invention makes it possible to connect stacks of paper webs to one another, regardless of how they are aligned with one another.

According to an exemplary development of the paper packaging material supply according to the invention, the

Paper web stack bridging section and / or the

Paper web stack connecting section from folded sheets of the paper web stack. Alternatively or additionally, the paper web stack bridging section and / or the paper web stack connecting section are / is made from one piece with a paper web of the paper web stack. This means that the corresponding paper web stack is not completely folded and stacked in a zigzag, but rather near-end folded sheets of the paper web have been pulled out of the columnar zigzag structure from the paper web stack underside, around the paper web stack bridging section and the To form paper web stack connection section, in particular to fold, and to be able to establish a connection or coupling with the adjacent paper web stack.

In a further exemplary embodiment of the paper packaging material supply according to the invention, a folded sheet of the adjoining the lower folded end sheet of the paper web stack is placed

Paper web stack bridging section fixed a paper web top. The paper web is such in particular to form the paper web stack bridging section, the

Paper web stack connecting section and to produce the coupling with the adjacent paper web stack folded over so that the top of the paper web in the area of the paper web stack connecting section comes into contact with the upper folded end sheet of the further paper web stack, in particular is glued to it. In other words, the paper web is folded to form the paper web stack bridging section and the

Paper web stack connecting section turned over by 180 °.

According to an exemplary development of the paper packaging material supply according to the invention, the paper web stack connecting section is folded over in the area of the further paper web stack along a third folding edge before it is connected to the upper folded end sheet of the further paper stack. The stability, in particular when transporting the paper packaging material supply, can advantageously be increased by means of the third folding edge.

According to a further exemplary embodiment of the present invention, the first, second and / or third folding edge is oriented at an angle to the longitudinal direction of the paper web. ^{For example, the angle is in the range from 0} ° to 90 °, in particular 30 ° to 60 °, in particular around 45 °.

In a further exemplary embodiment of the paper packaging material supply according to the invention, a folded sheet of the paper web stack bridging section adjoining the lower folded end sheet defines a paper web upper side. Furthermore, the paper web stack connecting section is folded over along the third folding edge in such a way that the paper web top side in the area of the Paper web stack connecting section facing away from the upper folded end sheet of the further paper web stack. In other words, the upper side of the paper web fixed in the region of the paper web stack bridging section points in the region of the further paper web stack in the same direction, in particular upwards, when it is connected to the further paper web stack. In particular, the paper web was turned over by o ° or by 360 ° or by 720 °.

In a further exemplary embodiment of the paper packaging material supply according to the invention, connecting web sections, in particular folded sections, of two paper web stacks arranged next to one another and connected to one another rest on a paper web stack top. In other words, the connection of two paper web stacks takes place on their upper side or on the upper side of paper web stacks which are placed one behind the other in the row direction of the stacks and / or essentially in a horizontal plane. For example, the stacks of paper webs are connected by means of folding. The paper web can be folded over along a folding edge in such a way that it is transported away from one stack to the other stack without twisting and / or without interruption. Preferably, the folding of the paper web is only carried out when the paper web is pulled upwards from an underlying folded end sheet of the one paper web stack and is then coupled to an upper folded end sheet of the downstream paper web stack. One advantage of connecting the paper web stacks on their top side or the top side of adjacent paper web stacks is that the connection does not have to be made on their end faces or vertical sides. The inventors of the present invention have found that it can be disadvantageous to arrange increased amounts of paper or the folds on the vertical sides or the end sides, since the paper web can flutter on the vertical sides or end sides and protrude from the paper web stacks. This has a particularly disadvantageous effect during transport. Furthermore, the stacks of paper webs are generally set up on pallets and thus fastened, in particular pressed, by means of tensioning belts or strapping bands, for example. By compressing the stack of paper webs, the effect of the loose fluttering around of the loose bridging and connecting sections on the front or vertical side increases. In an exemplary development, at least two rows of at least two zigzag-folded paper web stacks are arranged side by side transversely to the unfolding and / or consumption conveying direction, which are arranged one behind the other and connected to each other in each row in the unfolding and / or consumption conveying direction. The connecting sections rest at least partially on stacks of paper webs that lie behind them in each row in the unfolding and / or consumption conveying direction. An essential advantage associated with this type of connection is that wobbling or tilting of the stack of paper webs to be conveyed away and / or of an adjacent paper web stack can be avoided. By placing the connecting areas on adjacent paper web stacks, these are stabilized so that the influence of the air currents when the paper web stack to be removed can be compensated for.

In a further exemplary development, the paper web stacks each have an upper folded end sheet and a lower folded end sheet for placing the paper web stack on the base carrier, with a paper web stack bridging section adjoining the lower folded end sheet of one paper web stack protruding in the longitudinal direction of the paper web from this paper web stack, so that the Paper web stack bridging section rests on the upper folded end sheet, and is folded to connect to the upper folded sheet of the further paper web stack.

According to a further exemplary development, the paper web folding sections can hang on paper web stacks which, for each row, lie behind the associated paper web stack in the unfolding and / or consumption conveying direction.

Preferred embodiments are given in the subclaims.

In the following description of exemplary embodiments of paper packaging material supplies according to the invention is one according to the invention

Paper packaging material supply is generally designated by the reference number 1.

Paper packaging material supplies 1 according to the invention essentially comprise the following main components: a base support 3, which can be, for example, a transport pallet, such as a euro pallet or another internationally standardized transport pallet; and at least two zigzag-folded (leporello) paper web stacks 5, which are set up in the known Leporello folding column-like on the base support 3 and at least a height of 200 mm and a width of over 100 mm and a depth of over 50 mm exhibit. Each paper web stack 5 forms an uninterrupted, adhesive-free continuous paper web when the entire stack height is unfolded. One advantage of the present invention is that all the paper web stacks 5 arranged on the base carrier 3 are connected to one another to form an uninterrupted, endless common paper web, so that packaging delays due to reloading of the packaging machine can be avoided.

In the exemplary embodiments according to FIGS. 1 to 14, exemplary embodiments are shown of how the paper web stacks 5 can be arranged and connected to one another, the focus being on the fact that two paper web stacks 5, which transverse to their unfolding and / or consumption conveying direction, are next to one another the base carrier 3 are connected to one another, so that two rows of paper web stacks 5 can also be arranged next to one another on a base carrier 3, whereby the running meter performance of the paper packaging material supply 1 can be increased, in particular doubled.

1 shows an embodiment of a paper packaging material supply 1 according to the invention, in which a total of eight paper web stacks 5 are arranged on the base carrier 3, two rows 7, 9 each being formed by four paper web stacks 5. This means that per row 7, 9 four paper web stacks 5 in each case in the paper web longitudinal direction or unfolding and / or Consumption conveying direction are arranged one behind the other. The rows 7, 9 are arranged side by side at right angles to the unfolding and / or consumption conveying direction. Furthermore, the rows 7, 9 are arranged in such a way that two paper web stacks 5 arranged next to one another transversely to the unfolding and / or consumption conveying direction are essentially in alignment with one another. It can also be seen that the paper web stacks 5 are each arranged at a distance from one another such that a gap 11 is established between two adjacent paper web stacks 5, which is in particular at least 10 mm and preferably at most 100 mm. What is not shown is that the paper web stacks 5 per row 7, 9 can each be connected to one another, which is described in the utility model application DE 20 2014 008 810 Ui of the applicant and which is fully integrated herein with reference.

According to the invention, a paper web stack 5 of one row 7, 9 is connected to a paper web stack 5 of the other row 9, 7. 1 to 4 show a first variant of folding for the cross connection of two paper web stacks 5 arranged next to one another transversely to the unfolding and / or consumption conveying direction. Another advantage of the present invention becomes clear from the synopsis of FIGS. 1 and 2: In FIG. 1 it can be seen that the two front paper web stacks 5, which are arranged directly next to one another and / or are arranged at the same height with respect to the consumption conveying direction, be connected to each other. In Fig. 2 an embodiment is shown in which the foremost paper web stack 5 of the left row 7 is coupled to a rearmost paper web stack 5 of the right row 9, which results in a different order of processing or removal of the paper web stacks 5 that are on the base carrier 3 are arranged, results. 1 and 2 have in common that the connection between one row 7, 9 of the paper web stack 5 with the other row 9, 7 of the paper web stack 5 is realized by the same folding variant that is shown schematically in FIGS. 3 and 4 and which will be discussed in detail below.

Referring again to FIG. 1, it can be seen that the paper web of the foremost paper web stack 5 of the left row 7 protrudes from the lowermost folded end sheet 13 (FIGS. 3, 4) in the paper web longitudinal direction from the paper web stack 5. A so-called paper web stack bridging section 15 is thereby formed. The paper web stack bridging section 15 is folded over along a first folding edge 17 transversely to the longitudinal direction of the paper web. As can be seen in Figs. 3, 4, the fold 17 is orient wobbles at an angle of about 45 ⁰ with respect to the paper web longitudinal direction. Assigned in the area of the adjacent, the right row 9 of paper web stacks 5, the paper web stack 5 includes integrally on a so-called paper web stack connecting portion 19 which is formed in that the paper web stack bridging portion 15 along a second folding edge 21, which also transversely, in particular 45 ^0, facing the paper web longitudinal direction is folded over. The folding takes place in such a way that the paper web stack connecting section 19 extends essentially in the paper web longitudinal direction of the further paper web stack 5 of the adjacent row 9 of paper web stacks 5. As indicated schematically in FIGS. 1 and 2, the paper web stack connecting section 19 is formed by a plurality of folded sheets 23 of the paper web. The paper web stack connecting section 19 is connected to the adjacent paper web stack 5 of the further row 9 of paper web stacks 5, in particular glued, for example by means of an adhesive strip that can be covered, for example, by a protective film, or by a cold-sealable adhesive that is activated by applying pressure from the outside.

The paper web end sheet of the paper web stack connecting section 19 is placed on the upper folded end sheet 25 for connection to the paper web stack 5 and connected to it. In Fig. 2 it can be seen that the paper web stack connecting section 19 extends to a rearmost paper web stack 5 of the adjacent row 9 from the paper web stack 5 and also consists of folded sheets 23 of the corresponding paper web. Two adjacent folded sheets 23 that adjoin one another are connected to one another via a folding edge 27.

In FIGS. 3 and 4, hidden paper web edges or fold lines, which are not visible, are indicated by a dashed line. The paper web adopts an S-shape due to the specific folding. It can be seen that the embodiments of FIGS. 3 and 4 differ from one another only in the direction in which paper web stack bridging section 15 and

Paper web stack connecting portion 19 were each folded over, the Folding variant is the same, in particular the first and second folding edges 17, 21 are realized analogously.

A second folding variant is explained with reference to FIGS. 5 to 8. To avoid repetition, only the differences that arise in relation to the preceding explanations will be discussed. Basically, the paper packaging material supply 1 according to FIG. 5 is constructed analogously to the paper packaging material supply 1 according to FIG. 1, the paper packaging material supply 1 according to FIG. 6 analogously to the paper packaging material supply 1 according to FIG. 2. The difference with respect to FIGS. 5 and 6 and FIGS. 1 and 2 essentially consists in the folding variant. This is shown schematically in FIGS. 7 and 8. Referring to FIG. 5, it can be seen that the paper web stack connecting section 19 is folded over in the area of the further paper web stack 5 along a third folding edge 29 before it is connected to the upper folded end sheet 25 of the further paper web stack 5. This is particularly illustrated in FIGS. 7 and 8. The paper web takes in the area of the paper web stack bridging section 15 and

Paper web stack connecting portion 19 has a V-shaped shape due to the specific folding.

9 to 14 show schematically how paper web stacks 5 of paper packaging material supplies 1 according to the invention can be connected to one another, which is indicated schematically by the raised, straight arrows. The arrow directions indicate an unfolding and / or consumption conveying direction, with that paper web stack 5 in which the straight end of the arrow is located is first used.

9 and 10 show a top view of four paper web stacks 5 arranged on a base carrier 3. The arrows indicate the conveyance and connection of the paper web stacks 5. Referring to Fig. 9, it can be seen that first the paper web stack 5, left row, lower row is used up, then the adjacent paper web stack 5, left row 7, upper row of the same row as described above is connected to one another are. Then, according to one of the two folding variants according to FIGS. 1 to 4 or 5 to 8, a so-called cross connection takes place between the paper web stacks 5 adjacent rows 7, 9. This means that the paper web stack 5, right row 9, upper row is then processed and finally the paper web stack 5, right row 9, lower row arranged in the same row 9.

It is accordingly possible according to the invention to process and unfold all four paper web stacks 5 without interruption and without packaging delay and to feed them to a packaging material processing machine. The cross connection according to FIG. 9 essentially corresponds to that connection as shown schematically in FIGS. 1 and 5. In contrast to this, the cross-connection according to the embodiment according to FIG. 10 takes place in accordance with the exemplary embodiments shown in FIGS. 2 and 6 according to the paper packaging material supplies 1.

The embodiments in FIGS. 11 to 14 differ essentially in that a total of eight paper web stacks 5 are arranged on a base carrier 3, with two rows 7, 9 again being arranged next to one another and each having four paper web stacks 5. The conveyance and connection in FIG. 11 essentially corresponds to that from FIG. 10 and thus the paper packaging material supply 1 according to FIGS. 2 and 6. In FIG. 12, the conveyance in connection with the paper web stacks 5 according to FIG. which are thus represented analogously to the paper packaging material supplies 1 according to FIGS. 1 and 5. In FIGS. 13 and 14 alternative paper packaging material supplies 1 are shown, which essentially represent combinations of cross connections of FIGS. 1, 2 and 5, 6, respectively. An oblique arrow in FIGS. 10 to 13 generally indicates a cross connection according to FIGS. 2 and 6, while a straight arrow essentially indicates a cross connection according to FIGS. 1 and 5.

In FIGS. 15 to 22, paper packaging material supplies 1 are shown, in each of which three rows 7, 9, 7 of four paper web stacks 5 are arranged on a base carrier (not shown). A total of 12 paper web stacks 5 are thus stored on the base carrier. For each row 7, 9, 7, the four paper web stacks 5 are connected to one another in the unfolding and / or consumption conveying direction. In addition, cross connections are provided which are designed differently according to FIGS. 15 to 22. Figure 16 shows a zigzag conveyance of the paper packaging material supply 1, with an outer paper web stack 5 of the two outer paper web stack rows 7 being connected to an outer paper web stack 5 of the middle paper web stack row 9, in such a way that with respect to the unfolding and / or consumption conveying direction a frontmost paper web stack 5 is connected to a rearmost paper web stack 5 of the adjacent row.

In FIG. 15, an S-shaped conveyance of the paper packaging material supply 1 is shown. In each case, an outer paper web stack 5 of the two outer paper web stacks rows 7 are connected to an outer paper web stack 5 of the middle paper web stack row 9, so that in relation to the unfolding and / or consumption conveying direction, in each case a foremost paper web stack 5 with an adjacent, foremost paper web stack 5 of the neighboring ones Row is connected.

A combination of the cross connections according to FIGS. 15 and 16 is shown in FIG.

The cross connections from FIG. 18 are implemented essentially as in FIG. 15, the difference being that the two outer rows 7 are connected to one another by means of a cross connection, so that the middle row 9 is bridged. However, instead of bridging, it is also possible to form two cross-connections one after the other, so that, with regard to the unfolding and / or consumption conveying direction, a foremost paper web stack 5 of all three rows 7, 9, 7 is connected to an adjacent, foremost paper web stack 5 of the adjacent row. A further cross connection is then formed between one of the outer rows 7 and the middle row 9 on a side of the rows 7, 9 which is opposite with respect to the unfolding and / or consumption conveying direction. Subsequent to the cross connection, the middle row 9 is completely conveyed away.

The paper packaging material supplies 1 of FIGS. 19 and 21 have four cross connections, the paper packaging material supplies 1 each have eight cross connections.

In the paper packaging material supply 1 from FIG. 19, each cross connection is followed by a straight conveyance in the unfolding and / or consumption conveying direction. This means that after a cross connection at least two paper web stacks 5 of the same row 7, 9, 7 are used up before jumping to an adjacent row 7, 9, 7 by means of a cross connection. The same applies to the paper packaging material supply 1 from FIG. 21. The difference between the paper packaging material supply 1 according to FIG. 19 and the paper packaging material supply according to FIG. 21 is that in the plan view according to FIG S-shaped discharge is realized through the cross connections. This means that for each row 7, 9, 7 the unfolding and / or consumption conveying direction is always in the same direction in FIG. 19, while it changes in FIG.

The paper packaging material supply 1 from FIG. 20 essentially represents a combination of the embodiment of FIGS. Row 7 is changed, which then in unfolding and / or consumption conveying direction

In the paper packaging material supply 1 according to FIG. 22, which essentially corresponds to the paper packaging material supply 1 in FIG. 14 with regard to the type of cross connections, eight cross connections are also implemented, as in FIG. 20. In contrast to FIG. 14, each cross connection is followed by a further cross connection, so that the paper packaging material supply 1 as a whole is characterized by an S-shaped conveyance, whereby the paper tape stacks 5 adjacent to the unfolding and / or consumption conveying direction are consumed one after the other before a connection between two paper tape stacks 5 of the same row 7, 9, 7 is realized will.

FIG. 23 shows a schematic representation of the connection of two paper web stacks 5 adjacent transversely to the unfolding and / or consumption conveying direction, with only the two paper web stacks 5 to be connected being indicated in FIG. Row 7) and at the bottom right (row 9) in the paper web stack 5 marked in FIGS. 13 or 14. The connection of the paper web stacks 5 takes place along the connection direction, which is indicated by the arrow with the reference symbol R. It is clear that an opposite connection is also possible. The direction of view in FIG. 23 is to be understood as looking at the paper web stack 5 from above, so that the paper web sections shown in FIG. 23 lie essentially in a horizontal plane and / or on the upper side of the paper web stack. The two paper web stacks 5 are arranged at an enlarged distance from one another for the sake of simplicity, it being clear that the embodiment is also possible for all smaller distances from one another. On the respective paper web stacks 5 lies a section of the paper web, which is guided and pulled up from the lowest folded end sheet of the respective paper web stack 5 up to the respective paper web stack top side, which is identified as cover sheet 37 and is deposited on the upper folded end sheet of the respective paper web stack 5. Starting from the two cover sheets 37, the paper web stacks are connected by folding over the paper web. In FIG. 23, two different folding techniques are shown on the left and right.

Starting in the connecting direction R with the left paper web stack 5, which can belong to a left row 7 of paper web stacks 5, which are not shown, however, the cover sheet 37 is first continued over the extension of the paper web stack 5 and along a first folding edge 17, which is in one Angle is oriented transversely to the longitudinal direction of the paper web, folded over. At a second folding edge 21, a paper web is folded over again in such a way that it is not shown in the direction of the adjacent paper web stack 5 or in the direction of its row 9 of further paper web stacks 5 for the sake of simplicity. It is crucial that the second folding edge 21 is oriented at a different angle to the longitudinal direction of the paper web than the first folding edge 17. This means that the second folding edge 21 is not oriented parallel to the first folding edge 17. In contrast to the previous folding techniques, the paper web bridging section 15 is in several parts, ie it consists of several sections of paper web stack bridging sections, which are indicated by the reference symbols 15 ", 15", 15 "'.

The paper web is finally folded over again at a third folding edge 29, so that the paper web extends directly in the direction of the second paper web stack 5 to be connected. As can be seen in FIG. 23, there is essentially a V-shaped connection area. In order to realign the paper web to the paper web stack 5 to be connected, another double fold takes place along a fourth and fifth fold edges 30,31. In this respect, another difference compared to the previous folding techniques is that, corresponding to the paper web stack bridging sections 15 to 15 '", the paper web stack connecting sections 19 also consist of several parts or of several sections, which are indicated by the reference numerals 19' to 19 '". In contrast to the double fold on the left, the fold takes place in the region of the adjacent paper web stack 5 in such a way that a kink 35 results, at which both fold edges of the fourth and fifth fold edges merge. The paper web stack bridging sections 15 to 15 '"and

Paper web stack connection sections 19 to 19 '"therefore rest on paper web stacks 5 arranged behind them, viewed in the row direction, in particular on the paper web stack top side, i.e. on the respective upper folding end sheets 25. This allows the adjacent paper web stacks 5, which are not yet conveyed away, to be stabilized by means of the weight of the Connection areas of the paper web.

The features disclosed in the above description, the figures and the claims can be important both individually and in any combination for realizing the invention in the various configurations.
