Description

Palletized or palletizable arrangement for storage and transport purposes of a plurality of sanitary containing bag packages, wherein the bag packages are not included in cardboard packaging. A bag pack with typically folded hygiene articles received therein is referred to below as a primary pack. The term "hygiene article" is understood to mean, in particular, diapers, incontinence products, feminine hygiene products, panty liners, but also absorbent bed liners or underlays. Such incontinence articles are typically compliantly flexible and compressible, resulting in packaging on the one hand with the possibility of volume reduction and on the other hand with stability issues in stacking as packages form.

It is known to package bag packages containing hygiene articles in cartons, whereby a stable unit of a plurality of bag packages can be realized, which allows these units to be arranged side by side and one above the other in cartons and suitably, for example by means of straps or by means of stretchable packaging films, to fix, so that extensive containers can be formed.

For the production of cartonage-free arrangements of bag packages, the use of so-called edge support angles has already been proposed, see, for example EP 2 116 479 A1 , which extend along vertical edges and should have a stabilizing effect. However, their attachment is expensive. Furthermore, it is known to use so-called cardboard trays, each covering an entire horizontal position stacked bag packages and thereby prevent horizontal breakout of bags from this situation, also these cartons are to form a flat footprint for the bag packages the next following situation.

Furthermore, it is known to stabilize palletized assemblies by helical or horizontal stretch film windings. These prior art windings work without the use of cardboard to form stable units, however, only in connection with load units that have a certain sufficient stability, ie dimensional stability and stability, which is regularly not the case with sanitary containing bag packages due to the typically encountered compressibility. To increase the stability of compressible article containing bag packages was with EP 0 805 114 B1 further proposed to hold at least two bag packages by means of stretch film wrapping against each other while compressing to 20 to 70% of their original volume. Even by this measure alone can not be a satisfactory arrangement for storage and transport purposes realize.

The present invention has for its object to provide a palletized or palettable arrangement of sanitary containing bag packages, in which without the use of cardboard trays and without the use of edge support brackets or additional cardboard packaging of multiple bag packages in a cost-effective stable and dimensionally stable container for storage and transport purposes can be obtained.

• – die Anordnung umfasst mehrere zu separaten Sekundärpackungen zusammengefasste Einheiten von jeweils mehreren Beutelpackungen, wobei diese Sekundärpackungen auf einer Basis nebeneinander und in einer ersten Richtung senkrecht zu dieser Basis übereinander angeordnet sind;
• – eine jeweilige Sekundärpackung ist dadurch gebildet, dass eine jeweilige Einheit von mehreren Beutelpackungen zu einer Quaderform angeordnet ist und diese Quaderform von zwei separaten, zueinander um 90 Grad gedreht orientierten Stretchfolienumhüllungen in einer jeweiligen sich ergebenden Umfangsrichtung der Stretchfolienumhüllung vollständig umschlossen ist und dabei komprimiert ist;
• – die auf der Basis nebeneinander und in der ersten Richtung übereinander angeordneten Sekundärpackungen sind zur Bildung der Anordnung durch eine Vielzahl von Stretchfolienwicklungen aneinander gehalten;
• – die Stretchfolienwicklungen umfassen Kopfwicklungen, die einander im wesentlichen vollständig überdecken, Fußwicklungen, die einander im wesentlichen vollständig überdecken, und Schraubenwicklungen, welche ausgehend von den Kopfwicklungen schraubenförmig in Richtung auf die Fußwicklungen führen, und Schraubenwicklungen, welche ausgehend von den Fußwicklungen schraubenförmig in Richtung auf die Kopfwicklungen führen, wobei zusätzlich zwischen den Kopfwicklungen und den Fußwicklungen Stützwicklungen in einer Ebene im wesentlichen senkrecht zu der ersten Richtung, also im wesentlichen parallel zu den Kopfwicklungen und den Fußwicklungen, vorgesehen sind, die sich in der jeweiligen Ebene im wesentlichen vollständig überdecken.

This object is achieved according to the invention by a palletized or palettable arrangement having the following features:

• - The arrangement comprises a plurality of separate secondary packages combined units of a plurality of bag packages, said secondary packages are arranged on a base next to each other and in a first direction perpendicular to this base one above the other;
• A respective secondary package is formed by disposing a respective one of a plurality of bag packages in a cuboid shape and fully enclosing and thereby compressing this cuboid form of two separate stretch film wrappings oriented 90 degrees apart in a respective resulting circumferential direction of the stretch film wrapping;
• The secondary packages stacked on top of each other and in the first direction are held together by a plurality of stretch film windings to form the assembly;
• The stretch film windings comprise head windings substantially completely overlapping each other, foot windings substantially completely overlapping each other, and helical windings helically leading from the head windings toward the foot windings, and helical windings helically starting from the foot windings lead the head windings, wherein additionally between the head windings and the foot windings support windings in a plane substantially perpendicular to the first direction, that is substantially parallel to the head windings and the foot windings are provided, which completely overlap in the respective level substantially.

Starting from bag packages, each containing a plurality of in particular 5 to 60, typically folded hygiene articles, units are made of several such bag packages, about 2 to 24, in particular 2 to 10 and in particular 4 to 8 bag packages formed, with a cuboid shape and in particular a cube shape is obtained. Due to the two stretch film envelopes oriented at 90 ° to each other, a secondary pack compressed with respect to the original volume of the cuboid shape is obtained. It has further been found in accordance with the invention that these secondary packages can be stably fixed side by side and in the first direction one above the other without the use of cardboard packaging by providing stretch film windings comprising head windings, foot windings and helical windings around the stacked arrangement as mentioned above. The head windings are provided at the upper end of the assembly, that is, facing away from the base, and substantially with a circumferential direction extending in a plane substantially perpendicular to the first direction. They overlap completely, which means that a film web overlaps the preceding film web and preferably also the remaining film webs by at least 90% in width. In the same way, the foot windings run in the base-facing lower region of the arrangement. If the base, for example in the form of a pallet, is integrated into the arrangement, then the foot windings always comprise at least part of the base, so that the secondary packings are connected to the base or fixed to the base in this manner.

Furthermore, helical windings running in two directions, ie with opposite pitch of the "threads", are provided. They preferably connect directly to the head windings or foot windings, but this does not necessarily have to be the case. Furthermore, the aforementioned support windings are provided between the head windings and the foot windings, whose circumferential or winding direction - as in the head windings and foot windings - extends in a plane substantially perpendicular to the first direction. Also, the support windings have a substantially complete coverage, which in turn means that an overlap in the width of at least 90% is realized between stacked support windings. As with the head windings and the foot windings, there is no helical course with a defined screw direction in the support windings. It would be conceivable that the support windings are formed immediately after screw windings or vice versa, for example by a helical winding merges into a support winding or, in particular subsequently, a support winding merges into a helical winding or is continued.

Due to the interaction of the measures described above, according to the invention, a palletized or palletizable arrangement which satisfies the requirements of stability and dimensional stability required for this purpose is obtained for storage and transport purposes.

To produce the secondary packs, a unit of several relatively unstable primary packs is provided with 90 ° rotated mutually oriented stretch film wrappings and thereby compressed.

According to a first variant of the invention, it proves to be advantageous if the first attached to the cuboid stretch film wrapping is attached to the cuboid shape such that the stretch film wrapping forming flat material web runs parallel to the four longest sides of the cuboid shape. This is in 7a shown.

According to a second variant of the invention, the stretch film wrapping attached first to the cuboid shape is attached to the parallelepiped shape such that a flat material web forming the stretch film wrapping runs parallel to only two of the four longest sides of the cuboid shape. This is in 7b shown.

In both variants, the first-applied stretch film wrap is overlapped on two opposite sides of the cuboid shape by the second-attached stretch film wrap. The first stretch film wrapping thus lies directly against the cuboid shape on all four sides, while the second stretch film wrapping bears directly against the cuboid shape only on two opposite sides. Depending on the geometry of the cuboid shape, one or the other variant of the attachment of the two stretch film wrappings may prove advantageous in order to achieve a compression of the units, preferably in the range between 10 and 35%, in particular between 15 and 25%, wherein the Cuboid shape also behaves stable during the attachment of the first and second stretch film wrapping, so while not break out.

The first stretch film wrapping applied to the parallelepiped shape and the second stretch film wrapping oriented to the cuboid form rotated by 90 degrees thus result in a secondary packing in which the flat material webs forming the stretch film wrapping lie twice over one another on two opposite sides of the cuboid shape. Thus, thicker secondary packaging film areas are obtained without having to use a thick films for this purpose. Overall, a stabilization of this secondary pack is achieved on two opposite sides. These double layers also help prevent friction damage to the secondary package. Especially Advantageously, the double-lying flat material webs are formed on the two longest sides of the cuboidal shape of the secondary packing; This achieves a particularly well-stabilized secondary pack.

In a further embodiment of the invention, it proves to be particularly advantageous if the folded hygiene products are arranged with their flat sides lying together and forming a stacking form in a respective bag pack and the orientation of the stack shape within those bag packages that form a secondary pack is the same and the stretch film wrapping attached first to the cuboid shape is attached to the parallelepiped shape such that a flat material web forming the stretch film wrapping runs on two opposite sides of the parallelepiped shape parallel to the flat sides of the hygienic articles. This ensures that in the course of attaching the first inner stretch film wrapping the flat sides of the folded sanitary articles are pressed against each other; The hygiene articles are thus further compressed in their stacking direction, resulting in improved dimensional stability. According to a variant of the invention, it proves to be particularly advantageous if the folded hygiene articles are arranged with their flat sides lying against each other and forming a stacking form in a respective bag pack and the orientation of the stack shape within those bag packages which form a secondary pack is the same and the stretch film wrapping attached first to the cuboid shape is attached to the parallelepiped shape such that a flat material web forming the stretch film wrapping runs along the edges of the folded hygienic articles and thus orthogonal to their flat sides. Thus, the stretch film wrapping secondly attached to the cuboid form extends parallel to the flat sides of the sanitary articles on two opposite sides of the parallelepiped shape. This ensures that in the course of attaching the first inner stretch film wrapping first the bag packs are fixed together and then only in the course of attaching the second outer stretch film wrapping the flat sides of the folded hygiene products are pressed against each other. The hygiene articles are then further compressed in the stacking direction in the second step, which leads to greater dimensional stability. This second variant is particularly advantageous if the flat material webs forming the first and second stretch film wrappings are stretched to different extents during application to the cuboid shape, in particular if the second and thus outer stretch film wrapping is stretched to a greater extent than the flat material web forming the first stretch film wrapping. Thus, the folded sanitary articles can be compressed further in their stacking direction and damage to the hygiene articles by folding or crushing at the edges of the folded hygiene articles can be kept low.

The build-up of tension in the stretch film material caused by the stretching of the stretch film material then causes the compression of the secondary packing, of the bag packs or of the final hygiene articles arranged therein.

In principle, it would be conceivable for the two separate stretch film envelopes oriented mutually rotated by 90 ° to be attached by a single flat material web unwound in a respective circumferential direction, in particular also by a multiple wrapping. On the other hand, it proves to be advantageous if at least one and preferably both stretch film wrappings are each formed by two flat material webs of stretch film material fed endlessly on opposite sides of the cuboid shape and along the cuboid shape by separating two sections from the endlessly supplied flat material webs the flat material webs at two opposite ends of the cuboid shape against each other applied, separated and connected, in particular welded. In this way, one can realize a one-way oriented in a machine direction endless production of secondary packages. The respective cuboid unit of several bag packages is guided between the two endlessly supplied flat material webs in the machine. The preferred sequence of making the one, and preferably both, stretch film wrappings is such that with respect to a machine front end of the cuboid shape, the two sheets of flat material are joined and welded together and joined together. Against this connected end of the two flat material webs, the cuboid shape is pressed, such that there is a build-up of tension between the cuboid shape and the two flat material webs. The cuboid shape is effectively pressed against the weld seam between the two flat material webs and thereby compressed. At the rear end of the parallelepiped shape in the machine direction, the flat webs under tension are separated again and joined together, in particular welded. The term "welding off" is understood to mean a typically simultaneously occurring connection and separation of the flat material webs. The welding can be done thermally or by ultrasound.

For the production of the two mutually rotated by 90 ° oriented stretch film wrappings, it proves to be advantageous if the first stretch film wrapping forming flat material web of stretch film material during the Applying to the cuboid shape by at least 10%, in particular by at least 12% and more particularly by at most 30%, in particular by at most 25%, in particular by at most 20%, in particular by at most 18%, in particular by at most 15% and in particular by 12% 15% is stretched. The stretching of the flat material web of stretch film material is preferably carried out directly during the application, and advantageously by the fact that viewed relative to each other, the cuboid shape is conveyed at a greater speed against the connected end of the flat material webs than the flat material webs are supplied. The development of the flat material webs of a feed roller is thus relatively slower than the insertion speed of the cuboid shape between the flat material webs. Advantageously, the elongation of the first stretch film wrap is 12 to 15%.

Furthermore, it proves to be advantageous that a flat material web of stretch film material forming the second stretch film wrapping is stretched, at least as strongly, preferably more strongly, during application to the parallelepiped shape than the flat material web forming the first stretch film wrapping. It is in particular during the application to the cuboid shape by at least 12%, in particular by at least 15%, in particular by at least 18%, in particular by at most 40%, in particular by at most 35%, in particular by at most 30%, in particular by at most 25% and further stretched in particular by 18-25%. The film thickness of the flat material web of stretch film material is typically 20 to 80 .mu.m, in particular 20-60 .mu.m, more particularly, it may be 30-50 microns. Polyethylene films have proven themselves for this purpose.

It also proves to be advantageous if a respective flat material web of stretch film material forming the first and / or second stretch film wrapping has a width orthogonal to a longitudinal extent, ie circumferential direction, winding direction of the flat material web, which is at least 80%, in particular at least 90%, more particularly at least 100 % of a respective dimension corresponds to the cuboid sides to be enveloped, and more particularly 1-10%, in particular 2-5%, is greater than the relevant dimension of the cuboid side to be enveloped. Advantageously, the widths of the first and second stretch film wrapping forming flat material web are coordinated so that the cuboid shape is completely enveloped on all sides. If the width of the flat material web is greater than the width of the square side to be wrapped, on the one hand ensures a secure complete enclosure of the respective square side, and on the other hand, the circumferentially or winding direction extending edges and corners of the cuboid shape are surrounded by the flat material and something also rounded.

Furthermore, it proves to be advantageous that a volume reduction by attaching the first and second stretch film wrappings of the cuboid shape relative to the volume of the cuboid shape before attaching the Stretchfolienumhüllungen at least 10%, in particular at least 12%, in particular at least 15%, and at most 35%, in particular not more than 30%, in particular not more than 25% and in particular 15-25%. For the respective determination of the volume, the dimensions of the resulting cuboid shape before and after the attachment of the two stretch film envelopes are simply determined by dimensioning, wherein approximately rounded corners or edges are mathematically not taken into account.

In attaching the stretch film windings surrounding the juxtaposed and stacked secondary packages, the head windings, the foot windings, the screw windings, and the support windings could each be mounted separately through portions of stretch film material to be used therefor. However, it proves to be advantageous if the head windings, the foot windings and the coil windings and preferably also the support windings are formed by a single continuously wound flat material web.

With regard to the attachment and formation of the helical windings, it proves to be advantageous if the helical windings, starting from the head windings in the direction of the foot windings and the helical windings starting from the foot windings in the direction of the head windings differ in the degree of overlap, in particular the helical windings starting from the foot windings in FIG Direction of the head windings have a greater degree of coverage than the helical windings starting from the head windings in the direction of the foot windings. The degree of overlapping is understood here in relation to the immediately preceding wound material web.

For this purpose, it proves to be advantageous that the leading from the head windings in the direction of the foot windings coil windings a coverage of less than 40%, in particular less than 35%, in particular less than 30%, in particular more than 20% and more in particular from 23-27% to each other.

Next, it proves to be advantageous that starting from the foot windings towards the head windings leading screw windings have a degree of coverage of more than 40%, in particular more than 50%, in particular more than 60%, in particular more than 65%, in particular less than 80% and more particularly of 65-75% to each other.

The width of the stretch film winding forming flat material web is between 100-750 mm, in particular between 250 and 600 mm, preferably about 500 mm. The width of the flat film web forming the stretch film winding preferably corresponds to the extent of a secondary pack in the first direction. Further preferably, the width of the flat film web forming the stretch film winding exceeds the extent of a secondary pack in the first direction, since advantageously overfilling in the first direction vertically stacked secondary packs and thus stabilization of the palletized or palletable arrangement is achieved.

Advantageously, additional 1 to 5, in particular 1 to 4, in particular 1 to 3 support windings are provided between the head windings and the foot windings. For the attachment of the stretch film windings, so the head windings, foot windings, coil windings and support windings, it proves to be advantageous if a the stretch film windings forming flat material web of stretch film material is vorgereckt before applying to the side by side and in the first direction superimposed secondary packages, in particular by at least 100%, in particular by at least 120% and further in particular by at least 140%, more particularly up to a maximum of 200%, in particular up to a maximum of 190%, further in particular by 150-180% is vorgereckt.

The stretching or stretching by 100% means, based on the running meters of the material, that one meter of film (in the initial state) is extended by the stretching or stretching by 100%, ie to two meters.

A distinction here is a pre-stretching of a stretch film material of the stretch film windings of an application voltage, which only immediately upon application, d. H. Winding the flat web is generated. The stretching of a stretch film material is understood to mean an expansion preceding the immediate application, in particular between a supply roll and a take-off device. The final application voltage is established between this extraction device and the object to be wrapped. This two-stage build-up of tension in the stretch film material of the stretch film windings proves advantageous because it increases the stability of the wrapped arrangement to avoid over-stressing directly on the assembly, which otherwise poses a problem of secondary package slipping up to tipping over the assembly Consequence The relatively high two-stage stress build-up of pre-stretching and application tension then leads to a corresponding degree of relaxation of the stretch film material in the application state, ie after finalization of the stretch film windings, which is accompanied by a shrinking effect and thus a stabilization of the arrangement.

In development of the above inventive concept, it proves to be advantageous if the pre-stretched flat web of stretch film winding under an additional application tension (winding tension) is wound around the side by side and in the first direction stacked secondary packages and that the application voltage of an additional stretching of the already stretched stretch film to 15-40%, in particular by 20-40%, in particular by 20-35% of the anticipated length is provided.

A stretch film or a stretch film material is understood as meaning an elastically extensible flat material, ie a flat material which, when stretched, i. Elongation, has a resilience and can exercise restoring forces. As the stretch film material for both the flat material webs forming the first and second stretch film wrappings and the stretch film windings, various types such as cast films and / or blown films may be used.

Cast films are produced by distributing a liquefied granulate by means of a slot die on a water-cooled roll. The cast films here are stretch films, which can preferably be well stretched / stretched in the machine direction (MD), but preferably have little to no restoring forces perpendicular to the machine direction (CD).

The blown films are made by inflating the extruded film into a balloon and then packaging into a roll. A blown film is a stretch film, which preferably has restoring forces both in the machine direction (MD) and in the direction perpendicular thereto (CD).

The stretch film materials used for the stretch film wrappings and for the stretch film windings may preferably differ, in particular in the thickness of the stretch film material and / or in particular in the type of stretch film material used, ie blown film material or cast film material.

Preferably, a blown film is used for the flat material web forming the first and / or second stretch film wrapping, and a cast film is used for the flat material web forming the stretch film windings.

As stretch film materials for the Stretchfolienumhüllungen films have proven with a thickness of 20-80 microns, especially 20-60 microns, more particularly 30-50 microns.

As stretch film materials for the stretch film windings, films with a thickness of 15-50 .mu.m, in particular 15-40 .mu.m, more particularly of 15-30 microns have proven. The thickness measurement can, for example, according to DIN 53370: 2006-11 , Method P done.

Such films can be obtained, for example, from ITW Mima.

The palletized or palettable arrangement preferably has a height in the first direction of at least 1.50 m, in particular of at least 1.70 m, more particularly of at least 1.90 m, and more particularly of at most 2.50 m, more particularly of not more than 2.30 m, more particularly not more than 2.00 m.

The hygiene articles comprise in particular diapers, incontinence products, feminine hygiene products, panty liners or also absorbent bed liners or bed linens. The hygiene products are equipped with an absorbent body. The absorbent body comprises body fluid absorbent absorbent materials, such as natural or synthetic fibers, especially cellulosic fibers, preferably in the form of pulp fluff and / or intra-crosslinked cellulosic fibers. Preferably, the absorbent materials further comprise superabsorbent materials (SAP), especially based on surface-crosslinked, partially neutralized polyacrylates. The absorbent body preferably has a fraction of fibers, in particular of cellulose fibers, of at least 10% by weight, more particularly of at least 30% by weight, more particularly of at least 50% by weight, more particularly of at least 60% by weight.

As a basis, for example, conventional pallets, made of wood or plastic materials, in different sizes in question. Preferably, a Euro pallet with an area of in particular 800 × 1200 mm and height 144 mm is used.

First shows 1a a schematic representation of an exemplary number of six hygiene articles 2 , which are folded by way of example and typically one or more times, and thus a preferably substantially planar configuration with two opposite flat sides 3 exhibit. The hygiene products 2 can then use their flat pages 3 abutting each other in a bag pack 4 , typically made from a plastic film material ( 1b ). They preferably form a single stack form with stacking direction 5 , Such a bag package 4 with hygiene products 2 is hereinafter also referred to as primary pack 6 designated. 1c shows a unit 8th for example, four bags or primary packs 4 . 6 leading to a cuboid shape 10 arranged and through an additional packaging to be explained to a parallelepiped-shaped secondary pack 12 are summarized. 1d shows a variety of side by side and in a first direction 14 stacked secondary packages 12 (shown schematically without outer packaging), for storage and transport purposes to a palletized or palletizable arrangement 16 as they are in 5 is summarized, which will be explained in detail below.

With the reference number 18 is a base referred to, which may be, for example, a pallet, a trough or plate-shaped pad or the like.

2 shows schematically and by way of example the production of a parallelepiped-shaped secondary pack 12 from example four primary packs 6 , The respective stacking direction 5 the hygiene article 2 in the primary packs 6 is in 2 bottom left exemplified with an arrow; in an alternative embodiment, it could be orthogonal to the orientation shown (shown in phantom), and for all primary packages 6 a unit 8th preferably be the same direction. To form a secondary pack 12 becomes the cuboid shape 10 from example four primary packs 6 with a first stretch film wrapping 20 and with a second 90 ° twisted stretch film wrapping 22 embraced, which also means a compression, ie volume reduction of the original cuboid shape 10 accompanied. In the exemplary and preferred illustrated case, both the first and second stretch film wrappings are 20 respectively. 22 of two flat sheets of material 24 . 26 respectively. 28 . 30 made of stretch film material. With the reference number 32 is a machine or feeding direction for the respective cuboid shape 10 from primary packs 6 and for the flat material webs 24 to 30 designated. in the Course of feeding the cuboid shapes 10 and the flat material webs 24 . 26 become the flat material webs 24 . 26 in the machine direction 32 the respective cuboid shape 10 preemptively applied against each other and separated and connected, this advantageously a Abschweißvorgang is used. A device suitable for this purpose is shown schematically by the reference numeral 34 designated. In this way, a closed end 36 through the two flat material webs 24 . 26 educated. Against this closed end 36 becomes the cuboid shape 10 in the machine direction 32 with respect to the feed rate of the flat webs 24 . 26 Pressed increased feed rate, whereby an application voltage in the first and second flat material web 24 . 26 is built. The flat material webs 24 . 26 are then in the area of the machine direction 32 rear end of the respective cuboid shape 10 also applied against each other, separated and connected together, again preferably by a Abschweißvorgang, creating another closed end 40 at the flat material webs 24 . 26 is formed. As a result of the voltage generated in the flat material webs during insertion of the respective cuboid shape 24 . 26 becomes a total compression of the cuboid shape 10 in the machine direction 32 realized, and preferably in the initially mentioned in the introduction. Then the second stretch film wrapping 22 from appropriately supplied flat material webs 28 . 30 appropriate. This is the relative orientation between the cuboid shape 10 and in turn with reference numerals 32 designated machine or feed direction of the flat material webs 28 . 30 changed by 90 °, which expediently by a 90 ° rotation of the cuboid shape 10 happens. The cuboid shape 10 is then in a corresponding manner between the flat material webs 28 . 30 guided in a corresponding manner in the machine direction 32 at the front or rear end of the parallelepiped form against each other, separated and interconnected, with a further compression of the cuboid shape 10 in the machine direction 32 he follows. Finally, the in 2 bottom right parallelepiped shown 12 the cuboid shape 10 obtained whose outer dimension compared to the outer dimension of in 2 Lower left corner shown 10 is preferably reduced by the given in the description introduction dimensions. It should be noted that the flat material webs 24 to 30 preferably, but not necessarily, a width orthogonal to the respective machine or feed direction 32 which is larger than the corresponding dimension of the cuboid side to be enveloped.

7a clarifies that the first to the cuboid shape 10 attached stretch film cladding 20 such to the cuboid shape 10 attached is that the stretch film wrapping 20 forming flat material web 24 . 26 parallel to the four longest pages 42 the cuboid shape 10 runs. 7b clarifies that the first to the cuboid shape 10 attached stretch film cladding 20 such to the cuboid shape 10 attached is that the stretch film wrapping 20 forming flat material web 24 . 26 parallel to only two of the four longest pages 42 the cuboid shape 10 runs and thus also parallel to the two shorter or smaller sides 44 the cuboid shape 10 runs.

The secondary packages thus obtained 12 are preferably on a suitable basis 18 next to each other and in the first direction 14 arrange or stack on top of each other, so that a turn preferably cuboid overall arrangement arises. This arrangement is then used for stabilization and fixation with a variety of stretch film windings 48 fixed. 3 shows views in the course of applying Stretchfolienwicklungen 48 , wherein a schematically illustrated device usable for this purpose 50 for feeding and unrolling or wrapping a flat material web 52 of stretch film material is shown schematically; on the representation of a rocker for removing the sheet 52 from a roll to carry out stretching of the material was omitted. Out 3 it is apparent the attachment of head windings 54 , Footwraps 56 as well as coil windings 58 , which starting from the head windings 54 helical towards the foot turns 56 to lead. Corresponding coil windings 60 , however, in the opposite direction starting from the foot windings 56 towards the head windings 54 are for the sake of clarity in 3 not shown, but they are off 5 seen. Furthermore are off 3 two horizontally extending support windings 62 . 64 seen at a distance with respect to the first direction 14 to each other and at different heights between the head windings 54 and the footwraps 56 are provided.

It may prove advantageous that all windings of a single continuously wound flat material web 52 are formed, as already indicated at the outset. But this is not absolutely necessary. The different winding types can also be applied independently of one another and discontinuously, in particular also using flat material webs of various types, in particular of different feed rollers and / or feed devices. 4 shows an intermediate state when attaching the stretch film windings 48 with head windings 54 , Coil windings 58 and footwraps 56 and 5 shows the completed palletized or palletable arrangement 16 with all stretch film windings 48 , In detail:
The head windings and the foot windings preferably extend substantially in a circumferential direction or circumferential extent 66 which are approximately in a plane perpendicular to the first direction 14 runs, ie with vertical orientation of the palletized arrangement 16 extending approximately in a horizontal plane. The same is preferably true for the support windings 62 and 64 , The head windings 54 , Footwraps 56 and support windings 62 . 64 advantageously comprise multiple superimposed winding layers, whereby a required for storage and transport purposes stability is achieved. The coil windings 58 and 60 in contrast, run helically with respect to the first direction 14 , wherein at a respective winding 58 . 60 preferably maintained about a constant pitch. The pitch is advantageously such that partially overlap successively mounted coil windings, wherein the degree of coverage is advantageously carried out as specified in the introduction to the description. As mentioned there, the degree of overlap in the coil windings 60 which extend in the direction from foot to head, larger than in the helical coils 58 that move in the direction of head-to-toe, that is, counter to the first direction 14 extend. This is with the presentation of 6a and 6b indicated.

It should be noted that the arrangement 16 of secondary packs 12 in the manner described above and fixing stretch film windings 48 preferably formed by a pre-stretched flat material web. This means that the respective stretch film windings 48 forming flat material web 52 of stretch film material prior to application to the stacked array of secondary packages 12 pre-stretched, ie pre-stretched, which can typically be realized by a rocker pulling away the web from a feed roll. However, it would also be conceivable that the pre-stretching of the flat material web is carried out at an earlier point in time. When directly attaching the pre-stretched flat material web is then carried out as also in the introduction, an additional application voltage or winding tension in the flat material web 52 generated to an even increased tensile force in the direction of extension of the stretch film windings 48 to create.

The palletized or palletizable arrangement according to the invention, which in the finished state by way of example in 5 is shown, characterized by a high dimensional stability and stability, without that extensive cardboard boxes must be used for stabilization.
