Abstract

According to the invention, glass sheets are provided with a package consisting of at least one compliant layer and at least one reinforcing layer, the package being sent to the site with a carton, the carton wrapping the package as it is being transported and used to return the packaging upon arrival at the destination becomes.

Description

The invention relates to the packaging of disk-like cargo such as glass. Such goods include glass panes, especially flat glass panes, even more sensitive are natural stone slabs. Even bending and impact-resistant glass panes made of laminated glass have sensitive areas. These places are at the edges.

Flat glass comes in different forms, for example as toughened safety glass, as laminated safety glass, as laminated glass, as composite multi-pane glass, as fire-resistant glazing, as solar control glass, as thermally or chemically toughened glass, as float glass, as heat protection glass, as wire glass, as Window glass, as cast glass, as soundproof glass, as garden glazing. The different types of glass are mostly standardized. For example DIN 12150 . DIN EN ISO 12543 . DIN 1259 . DIN 4102 . DIN 1863 . DIN 11525 . DIN 11526 , DIN 52290

Often the load carriers are unloaded with the glass at the construction site. The carrier has significant disadvantages:

A designed as a carrier special vehicle is not suitable for other transports. The vehicle must wait at the construction site until all glass panes have been installed or a secure intermediate storage of the glass panes must be established.

The load carriers are rigid and can be mounted or locked onto vehicles, in which the glass is fixed upright. The transport costs for such studs are disproportionately high. It must be taken into account that the stands not only have to be transported to the construction site, but also have to be picked up again. It must also be calculated that the truck usually used for transporting glass is not approximately utilized with the stud frame and the glass. Not infrequently there are cost offers for glass in which the cost of transporting the glass is just as high as the cost of the glass.

A vehicle with a removable carrier is suitable for other tasks.

However, the charge carrier takes up a great deal of charge space and is an obstacle to an additional charge.

The load carrier is deposited at the construction site. After installation of the glass panes, the load carrier must be picked up again.

Both causes high transport costs. In addition, there are usually significant additional costs if the carriers are not released immediately. The release usually delays as soon as it comes to the glass installation to default. Then you want to store the glass in the load carriers until use, because any other storage involves much greater risk of damage to the glass.

Also on cargo, which consists partly of glass, the same problem arises as in the glass sheets described above. This applies, for example, to photovoltaic elements / solar cells.

With natural stone slabs a similar situation is given as with the glass panes. However, the natural stone slabs are even more sensitive than glass panes due to the inhomogeneity of natural stone slabs. Natural stone slabs of small thickness break even at low bending load. The natural stone slabs are also transported upright in a load carrier to the customer. Natural stone slabs are also widely used as floorboards and window sills in construction.

But other cargo easily undergoes damage. This includes even worktops that otherwise withstand significant loads.

The worktops are sensitive to sharp edges.

The edge sensitivity is the biggest damage problem on many items to be transported. This not only applies to other disk-shaped cargo, but also for cuboid transport goods.

For edge protection, a novel packaging has been developed. The details are in the PCT / EP2013 / 2697 described.

• a)ein die Kanten umfassender Kantenschutz
• b)bestehend aus nachgiebigem Material, insbesondere mit einem nachgiebigen Kunststoffschaum(Nachgiebigkeitsmaterial), und c)bestehend aus einem Verstärkungsmaterial.
• d)wobei nachgiebiges Material zumindest teilweise zwischen dem Verstärkungsmaterial und der zu schützenden Kante angeordnet ist.

It is essential

• a) the edges comprehensive edge protection
• b) consisting of resilient material, in particular with a flexible plastic foam (compliance material), and c) consisting of a reinforcing material.
• d) wherein resilient material is at least partially disposed between the reinforcing material and the edge to be protected.

Any pressure that would cause edge damage without edge protection (edge damage pressure) is absorbed by the edge protector. As far as doing a part of the pressure propagates in the direction of the edge to be protected, is this pressure from the reinforcing material of the edge protector is distributed over the compliance material broadly over the edges. As a result, the pressure acting on the edges is reduced so much that the edges readily withstand the pressure.

An edge protection with plastic foam is known per se. In this case, the cargo is usually full surface covered with plastic foam and then covered with cardboard. The cardboard has a much lower resistance than the plastic foam. That is, throughout the package construction, the plastic foam is the stronger material / reinforcing material over the cardboard and the cardboard is the more compliant material / compliance material.

It turns out that the edge protection according to the invention is considerably better than the conventional edge protection.

The compliant layer of the present invention is at least 20% more compliant relative to the reinforcing layer, more preferably at least 40%, still more preferably at least 60%, and most preferably at least 80% more compliant than the reinforcing material. The compliance is understood as a measure of the compression, which experiences a material cube with an edge length of 1cm with flat support when it is subjected to a drop weight of 1kg and with respect to the cube surface parallel interface from a drop height of 10cm.

Advantageous is a multi-layered design with at least two layers of reinforcing material, wherein not only between the reinforcing material and the edge of the transported good a layer of compliance material is provided, but also a layer of compliance material is provided between the two layers of reinforcing material. This has a favorable influence on the deformation behavior of the edge protection.

The compliance material is preferably laterally opposite the outer surfaces of the cargo, even more preferably, the edge protection comprises the cargo at the edges. Most preferably, the reinforcing material protrudes laterally relative to the respective outer surface of the transported goods and / or protrudes the reinforcing material into the part of the compliant material that comprises the transported goods.

The reinforcing material may be metallic or made of plastic. The metals used are preferably aluminum and other metals with a low specific weight.

Foamed plastics are preferably used as compliance materials. Foamed polyethylene plastics and polystyrene plastics are already common in the packaging sector. This is due to the low cost of such foams. Conventional packaging foams have a low density (weight per unit area). Advantageously, same foams with higher density can serve as reinforcing material. The density is adjusted by the addition of the propellant. The higher the addition of propellant, the lower the volumetric weight and the higher the resilience of the foam. The lower the addition of propellant, the higher the volumetric weight and the lower the compliance.

The reinforcing material may also be organic or inorganic type. Organic reinforcing material may be wood.

Economical are wood profiles, especially in a straight shape.

Even simple profiles with a rectangular cross-section can fulfill the desired amplification function. For straight reinforcing profiles, wooden bars, even roof battens, can be a very economical solution. Inorganic reinforcing material can be made of glass fibers, for example. The glass fibers can enclose the pliability material as a mesh fabric and thereby form the reinforcing material described above.

The battens are standardized according to DIN 4047-1. Standardization ensures certain dimensions of 30 × 50 mm or 40 × 60 mm. However, most of the roof batts traded on the market are not up to standard. With these battens, an excess of 1 to 2mm is generally to be expected. The greater accuracy according to DIN is advantageous because the reinforcing profile can then slide with much less play in the compliance material or conversely, the compliance material can be pushed onto the reinforcing material. The roof battens are an extremely economical reinforcing material.

Experiments have shown that with the roof battens as a reinforcing material and a compliance material surrounding the roof battens of an extruded polystyrene foam, a float glass panel could be dropped without damage. The float glass is very sensitive to other discs. The float glass had a thickness of 6mm and an area of 1 square meter. The polystyrene foam was a common, closed-cell construction foam for the external insulation of buildings with a density of 30kg per cubic meter. Such foam is at least 95% closed-cell. From the density of the properties of the foam, in particular the compliance can be derived. The polystyrene foam had a thickness of 100 mm. The inventively reinforced polystyrene foam was held by a strapping with a 10mm wide and 0.5mm thick steel strip on the edge of the window.

The glass pane was dropped differently, so that the glass pane with the packaging has experienced very different loads when it hits the ground.

The drop height was unrealistically high at 2.5m. All the more surprising is the result of the experiments. After the sixth attempt repetition had to be canceled because the strapping had solved. However, the glass had not taken any damage until then. During the experiments it could be observed that the glass sheet together with its packaging can undergo extraordinary bending without breaking.

Experiments with a sandstone slab with a thickness of 20 mm were also successful at the same edge protection and multiple strapping with a reduced drop height of Im, also in repetition.

The strapping is preferably carried out on the long sides.

Even better results can be achieved with steel hollow sections or aluminum profiles instead of roof battens. The aluminum profiles have given the steel profiles the advantage of lower weight. However, these metal profiles cause significantly higher packaging costs, so that a return of the packaging to the supplier for their reuse is recommended. In the case of packaging with edge protection made of particle foam and roof battens, the packaging costs are so low that disposal instead of recycling is also possible.

In the case of curved shapes and / or in the case of more complicated cross sections, the production of the reinforcing material made of plastic, in particular of unfoamed plastic, may be more favorable. To reduce costs, it is advisable to provide the plastic with fillers and / or use recycled material as plastic. The filling material can also be wood. The wood is reduced to a size that can be used in the plant intended for the processing of the plastic. The filler has in the mixture with the plastic at least a proportion of 50% by weight, more preferably of at least 60% by weight, and most preferably a proportion of at least 70% by weight. The plastic used is preferably a polyolefin such as polyethylene or polystyrene.

For the processing of plastic with filler are particularly suitable extrusion systems in which the plastic is mixed with the filler and other additives. The plastic is melted so that the other mixture proportions can be easily mixed in the plastic. The mixture is then cooled to exit temperature in the extruder and forced through a nozzle which gives the material to be discharged the desired shape. The leaking material cools and retains the acquired shape.

Optionally, the melt can also be injected into a mold. Upon cooling of the melt in the mold, the melt retains the shape of the mold cavity. One speaks of molded parts or of the production by injection molding.

The compliance material is preferably made of foamed plastic, preferably a polyolefin foam such as polystyrene foam.

The foam may be a particle foam or an extruded foam.

The particle foam consists of a large number of foam particles. The foam particles can be produced in the autoclave. In this case, plastic particles are produced by polymerization of monomers and then loaded with a blowing agent, so that the plastic particles foam when they are left after heating in a pressurized container to the outside.

The foamed particles are filled into a mold cavity having the desired shape of the compliance material provided for edge protection. The particles are usually supplied with superheated steam in the mold cavity, so that the particles melt on the outer surface and stick or weld to adjacent particles. The glued or welded particles take on the shape of the mold cavity. The moldings can be removed from the mold cavity.

The compliant material can also be made as a foam by extrusion.

In this case, plastic is brought under considerable pressure by heating in molten form and mixed with aggregates and with a blowing agent and, as explained above, cooled to outlet temperature, to then be pressed through a nozzle. By leaving the Extruder passes the melt from a high pressure area to an area where ambient pressure prevails. Due to the pressure drop, the propellant reacts. It expands and, with simultaneous cooling of the melt, forms a large number of cells in the melt. The expansion is limited by a calibrator, which is modeled on the desired cross-sectional shape of the foam strand.

The mixed with propellant melt can also be injected into a mold that gives the plastic foam forming the desired shape.

For the production of moldings for the compliance material and particle foam can be used. Particle foam consists of foam particles. The foam particles are filled with a certain pressure into a mold which, like the injection mold, corresponds to the desired shape of the plastic parts. In the mold, the foam particles are steamed with superheated steam, so that the foam particles melt on the surface and weld together under the existing pressure.

With the same volume density, an extruded foam has better strength properties than a particle foam.

Conventional extruded foam of polystyrene has a closed cell density of 95% and more, based on the variety of all cells.

For compliance, it may also be advantageous to use a foam that is open-celled more than the 5% of a conventional construction foam, based on the variety of all cells. Preferably, the open cell content is then at least 10%, more preferably at least 20% and most preferably at least 30%. That is, of the total number of cells in the foam, a part corresponding to the specified% set is not closed but open, so that gas trapped from these cells can escape under stress / pressure. The multiplicity of all cells is determined by means of a sample, for example using a cube cut out of the foam with an edge length of 1 cm. Each cube surface is a cut surface. It is then counted on a cube area of 1cm × 1cm, the number of all cells. Furthermore, it is assumed that these are spherical cells, so that it is possible to determine the average number of cells based on the number of cells counted and on the area. From the average diameter, the volume of the cells can be determined and the volume of the number of all cells in the sample or another foam body determine.

For cell formation, a propellant gas is used. The propellant gas expands in molten / softened polystyrene when the ambient pressure is correspondingly reduced.

This happens when extruding, when the laden with the propellant melt exits the extruder, in which there is a much higher pressure than the ambient pressure in the surrounding atmosphere.

This occurs in the production of particle foam, when the foaming laden with unexpanded or slightly pre-foamed polystyrene particles are softened in an autoclave and pressure and temperature and then released quickly from the autoclave.

The propellant dose is critical to the question of whether a customary, largely closed-cell construction foam is generated or whether an open-celled foam is generated. In carbon dioxide-containing blowing agents which are customary today, the proportion of blowing agent in the mixture for customary construction foam is between 5 and 8% by weight. By gradually increasing the proportion of blowing agent you can approach the desired open-celledness.

The trapped in the closed cells of the foam usual propellant does not stay there. It diffuses through the cell walls and ambient air diffuses through the closed cell walls. The diffusion processes take some time. Usually, the utilization of such foam products is waited until the diffusion processes are largely completed.

The open cells have holes in the cell walls. The originally present there blowing agent is displaced very quickly by ambient air. However, the trapped air is also forced out of the cells by mechanical deformation of the foam used as the compliant layer. This facilitates the deformation compared to a closed-cell foam. There the air remains trapped and must stretch the cell walls to yield to the pressure.

Preferably, the open cell content is limited to a maximum of 50%, even more preferably to 60%. Then there are still so many closed cells in the foam that the foam will reform again shortly after it has been released.

The compliant material and the reinforcing material may also be stacked in multiple layers (layered). In this case, the compliance material and / or the reinforcing material may vary or be the same from layer to layer or from layer to layer.

A variation of the compliance material may be given, for example, if a compliance layer / layer is also formed as a cushioning layer. The damping layer differs from conventional plastic foam in that no deformation or recovery takes place when the layer is deformed and after subsequent relief, but rather that a return deformation / recovery takes place with considerable delay. With such a damping property prevents the package including the packaged goods, for example, after a fall in vibration. The vibration can lead to a hopping, so that sensitive float glass is not burdened solely by the fall, but by subsequent hopping and regurgitation on the ground.

The desired damping properties have, for example, an open-cell foam layer as described above.

Optionally, the reinforcing material may comprise the compliance material or vice versa. Alternatively, the reinforcing material may also be contained in the compliance material or vice versa.

When the packaging is produced in sections, it may be advantageous if two adjacent sections engage one section in the other. This can be used to connect the packaging sections in the longitudinal direction. This can also be used to connect packages that are next to each other.

The compound may be permanent or solvable.

For the connection pins or pins may be used, the pins or pins may be formed on a packaging portion and engage in corresponding openings of the adjacent, adjacent packaging section. It can also be used separate pins and pins, which engage in opposite openings of two adjacent packaging sections. Several pins simultaneously prevent twisting of the packaging sections against each other. Off-center pins also prevent a rotation of the packaging sections against each other. Moreover, with pins whose cross section (for example, a polygonal cross section) deviates from a circular cross section, twisting of the packaging sections against each other can likewise be prevented. Through a rotationally secure connection, the properties of the interconnected packaging sections approach the properties of a one-piece packaging part of the same length as the interconnected packaging sections.

A further approximation can be achieved if the pins and pins are held firmly in the corresponding packaging sections. This can be achieved by thickening the pins or pins which result in a press fit in the corresponding packing sections. Optionally, the pins or pins with their thickening can also engage in undercuts of the recesses in the corresponding packaging sections.

As stated above, it is favorable if the edge of the packaged item to be protected is first covered with yielding material and combined with reinforcing material at a distance from the edge to be protected. The reinforcing material and the compliance material may, however, also comprise one another or simultaneously engage one another at the same time. Preferably, the compliance material is formed in cross-section as a symmetrical profile body and takes this profile body in each case at least one reinforcing profile in an opening. Optionally, two reinforcing profiles are provided in two spaced openings of the edge protector.

Advantageously, can be pushed onto the reinforcing material forming profile body packing sections of compliance material (thread) and connect with each other.

Optionally, the packaging sections can also already be arranged one behind the other, and then a profile body forming the reinforcing material can be pushed through the associated opening in the packaging sections.

It is also the use of plastic foam for the reinforcement profiles possible. The necessary strength of the reinforcing profiles forming plastic foam obtained by a corresponding higher density and / or by a Skirting of the profiles on the outer surfaces. The skin formation occurs when the outer surfaces are heated to such an extent that the foam collapses in this area. For this purpose, rapid heating is advantageous. For this technique is favorable that the plastic foam has a very low thermal conductivity. The skin formation causes after cooling a considerable stiffening of the outer surface. The cooling can be accelerated with aids.

Alternatively, instead of the skin or additionally a stiffening by a Coating the Verkärkungsprofile be achieved from plastic foam.

As a coating, unfoamed films or textiles are suitable. Favorable are films and textiles, which also consist of plastic and are laminated onto the reinforcing profiles. For laminating counts according to the invention, a welding as well as a bond.

But even metallic films can be laminated on plastic foam profiles. The connection between metal and plastic foam can be effected by adhesive. Because of the details of the laminating technique, reference is made to the following publications: DE602004013008 . DE202010008929 . DE202010008532 . DE20200900339 . DE20200900692 . DE202008017621 , DE2020080016847, DE202008013755 . DE202008012066 . DE202008004965 , DE20200701806r4, DE202006017392 . DE1020111199668 . DE102011100025 . DE102010053740 . DE 102020050874 . DE102010030310 . DE102009046413 . DE1020090141574 ,

The strong outer layer can also be a plastic foam with the same flexibility as the compliance material to a reinforcing material.

The intended for the compliance material plastic foam is, for example, a polystyrene foam with a density of 25 to 40 kg per cubic meter. The polystyrene foam may be conventional foam having a closed cell density of at least 95% based on the number of cells. To achieve an increased damping behavior, the foam may have a greater open cell density than 10%, preferably at least 20%, more preferably at least 30%, based on the number of cells.

Preferably, the package comprises the edge of the cargo to be protected U-shaped, so that the edge protection according to the invention can not only absorb forces that extend in the plane of the disk-shaped cargo (for example glass), but can also absorb forces which extend transversely thereto.

The reinforcing material may have a similar or similar shape as the packaging in order to withstand the forces extending transversely to the plane of the disc-shaped transport goods. The invention has recognized that sufficient protection is already achieved when the reinforcing material protrudes transversely to the plane of the disk-shaped material to be transported in relation to the transported goods and, moreover, has a frictional connection with the transported goods via the yielding material. In this sense, the above-described wood profiles with rectangular cross section (roof battens with a cross section of 30 x 50 mm or 40 x 60 mm) may be sufficient for the edge protection according to the invention. The simultaneously desired frictional connection between the compliant material / foam and reinforcing material / wood is preferably achieved by embedding the wood profiles or the reinforcing material in the compliance material. In this case, the compliance material can form the part with which the packaging comprises the edge to be protected.

The reinforcing material may be firmly connected to the compliance material. But it can also be as in the case of the above-mentioned wood profiles reinforcement by separate (loosely sitting in the package profiles of organic material or inorganic material or metal or plastic are formed.

It is also within the scope of the invention that instead of the described reinforcing profiles or in addition to the described reinforcing profiles to make a different reinforcement of the compliance material. Preferably, the other reinforcement is achieved by the already described skin formation and / or by laminating films and / or textiles.

Likewise, within the scope of the invention, a reinforcement is also to be made by enveloping the compliance material with films or textiles.

Optionally, the compliance material and / or the reinforcing material may be composed of different parts. In the case of the reinforcing material, this has already been illustrated using the example of various materials. But also the compliance material can be composed of separate parts.

The multi-part design can be used regardless of the type of material. The multi-part design can be used to bring together materials of different nature or to gain rationalization advantages.

For large series, a rationalization gain is achieved by the one-piece production of the edge protection.

For a smaller series, a rationalization advantage is obtained when, for example, for different widths / thicknesses / heights for producing the edge protector, different profiles are combined get connected. Preferably identical profiles are used as possible and fitting pieces are used with which the different widths / thicknesses / heights are generated.

Advantageously, the system is applicable to different cross sections, for example round cross sections and square cross sections, rectangular cross sections, square cross sections, other triangular, quadrangular and polygonal cross sections.

Optionally, this system also applies to individual profile cross-sections. Each profile cross-section can be composed of several profiles. In this case, the profiles which form the ends of a profile cross-section can be referred to as side profiles and the profiles which form the fitting pieces between the side profiles can be referred to as center profiles.

The profiles can be the same or different.

In the frame, identical or different side profiles (profiles which form at least one outer side on the packaging) and identical or different center profiles can be used. The center profiles can be the same and be supplemented with different side profiles to form an overall profile.

The same applies to internal profiles, external profiles and other center profiles.

Optionally, the various profiles are connected permanently or detachably. Preferably, the permanent connection is made by welding or gluing. Preferably, the releasable connection is made by telescoping the profiles.

In the application of this teaching to foam profiles this means: the foam starting profiles can be joined by welding or gluing to form the edge protection overall profile. When welding, the welding surfaces must be melted. When melting foam surfaces, it should be borne in mind that, depending on the duration of the process, more or fewer cells collapse at the welding surface and therefore a reduction in thickness is to be expected. The thickness reduction is taken into account by using thicker initial profiles, so that the resulting overall profiles get the desired dimensions. The correct initial dimension can be determined with just a few tests.

The necessary heating of the welding surfaces can be produced by contact with heated welding tools, but also with radiant heat or hot gas. Hot gas welding also makes it easy to achieve even complex welding surfaces.

When gluing the initial profiles different adhesives can be used. With adhesives, even with hot-melt adhesives, a melting of the adhesive surfaces / bonding surfaces on the starting profiles is prevented, as long as the application temperature of the adhesive is below the melting temperature of the compliance material.

Particularly high bond strengths can be achieved with reactive adhesives. However, the reaction adhesives are usually more expensive than other adhesives. Hot melt adhesives are inexpensive and have proven themselves many times. In addition, the gluing has the advantage that different, not or only poorly weldable materials can be interconnected. This applies, for example, to the connection of plastic with metal.

That gives further design freedom.

Another example relates to the adaptation of the edge protector to different thicknesses of the disk-shaped transport goods (for example glass). Optionally located in the edge protection one of the largest thickness of the transported material to be protected adapted recess for receiving the cargo at their edge to be protected. For smaller thicknesses, an insert is optionally provided in the recess for the edge to be protected (for example, the glass edge). The insert fills the recess so far that the edge protection can be placed closing on the edge or vice versa, the disc-shaped cargo can be closed in the recess of the edge protection.

Optionally, the recess in the edge protection for receiving the edge is also stepped. Then, the opening in the edge protector tapers in at least one step, so that the recess with the largest opening width, for example, can receive glass sheets with a thickness of 8 mm and can receive in the underlying taper a glass pane with a thickness of 6 mm.

For further details on the PCT / EP2013 / 2697 Referenced. As far as the ends of the edge protection sections are mitred, the miter angle is preferably 45 degrees with mutually perpendicular edge protection sections. In mutually opposite ends of edge protection portions of the miter angle is preferably equal to half the angle that the ends of each other the edge protection portions between them.

As stated above, during strapping, the forces acting on the edge protector are greatest at the corners of the edge protector and this is optionally taken into account with an additional corner reinforcement. Regardless of the corner load, the corner reinforcement may have other reasons: for example, an additional function such as a transport aid. The transport aids can complement the edge protection according to the invention in a very advantageous manner. They improve handling and thus reduce the risk of damage to the packaging and the packaged goods. However, the transport aids are also independent of the edge protection according to the invention for other packaging advantageous.

The transport aid may be a handle, loop, eyelet, hook. The eyelets can serve different purposes. The eyelets are suitable for attaching clamping devices for load securing during transport. The eyelets are also suitable for striking handles. Advantageously, the eyelets can even form a handle with a simple additional part. This can be done with two spaced eyelets and a rod, for example a wooden rod. The spaced eyelets can be connected together by the rod, so that the packaging with the enclosed cargo can be carried on the rods.

It is favorable if the eyelets have such an opening width that the rod can be inserted through both eyelets. The rod then forms a handle together with the eyelets.

Likewise, a role is suitable as a transport aid. The same applies to forklift feet, containers, fasteners or connections for a transport lock. The containers are of considerable advantage for various applications of the packaging. This is especially true if, for example, with one or more glass panes fasteners / assembly aids / assembly instructions / accompanying documents to be transported. This is especially the case when glass parts / kits for showers are transported. Different sized containers can be provided for the different applications.

The transport aids can also consist of plastic foam. The transport aids can also consist of other materials, including a composite of plastic foam with other materials. Preferably, containers are selected from unfoamed / low-foamed plastic, as long as it does not depend on damping against impact load. It is advantageous to manufacture such containers from the same plastic as the plastic foam for packaging and to connect them with plastic foam parts with which the containers engage in the grooves on the packaging. The plastic foam parts are then modeled on the cross-sectional shape of the grooves. The plastic foam can be well connected to the containers by gluing. Suitable adhesives include known hot melt adhesives. The connection can also be made by welding, when the containers and their grooving parts for welding have a sufficient consistency in nature.

The multi-part design of the container is in small series advantageous because then common parts can be kept for all sizes. Such common parts are at least the molded parts with which the containers engage in the grooves of the packaging. In addition, it may be advantageous to realize different container volumes with tubular containers, which are closed at both ends by lids and are adjusted by selecting the length of the desired volume. The tubular containers preferably have a rectangular or square cross-section to facilitate connection to the mold members with which the containers engage in the grooves of the package.

In this case, the transport aid must not be attached directly to the packaging, but it is sufficient if the packaging has a connection for a transport aid or allowed the installation of transport aids. In this case, attachment to the compliance material and / or the reinforcing material and / or to the strapping, on the strap or the strap is possible. The transport aids can be permanently attached or detachably mounted. Such a terminal may for example be formed by an external and / or internal terminal surface and one or more openings for securing / retaining bolts. It is favorable if the transport aid is slipped over the connection and then secured with a bolt. The various transport aids can moreover be integrated in a packaging section. This is especially true for forklift feet and wheels.

When the hooks, it may be advantageous if the hooks are fork-shaped to be able to grab on both sides of the strapping, strap or strap in the packaging.

Preferably grooves are provided in the packaging, in particular in the compliance material, in which the transport aids are inserted or pressed in with a suitable spring can be. For the tongue and groove connection, a dovetail shape or a shape ajar to the dovetail shape is favorable. Such compounds are particularly stable, but can be difficult to handle with little play. Tongue-and-groove joints are easier to handle where the spring has a rounded shape so that the spring can be pressed into the groove transversely to the longitudinal direction and pulled out again in the opposite way. In this case, the groove may include the spring closing, the opening width of the groove must be smaller than the diameter of the spring, so that the spring is included. The smaller the opening width, the more effort is required to push the spring transversely to the longitudinal direction in the groove. With a few attempts, a balanced opening dimension of the groove can be determined, in which the spring can still be pressed with reasonable effort by hand into the groove and has sufficient hold in the groove.

The grooves can be machined into the plastic foam. Suitable methods are, for example, milling and / or sawing.

The grooves can also be molded into the plastic foam. This then happens preferably in the production of the plastic foam. For example in the form described above by means of a correspondingly shaped extrusion die and a correspondingly shaped calibrator. In this case, preferably round corners (both inside corners and outside corners) are produced in the groove and corresponding corresponding round corners on the cross into the groove transport aids.

The grooves can also arise during the shaping of the packaging sections in a molding machine or in an injection mold.

In addition, the non-cutting and the cutting deformation can be combined with each other by the grooves in the form of non-cutting deformation partially arise and the final processing by milling or sawing.

The grooves according to the invention preferably run on the sides (front and back) of the packaging sections and on the outer surfaces (including top and bottom) of the packaging sections around the packaging. The transport aids can be inserted at will / need in the grooves.

The rollers are inserted at the bottom, the associated handles on the side of the package in a comfortable height for the transport people.

The forklift feet or other feet are also inserted at the bottom. Hooks and pins can be inserted on the sides, hooks and eyes not only on the sides, but also on the top. The same applies to connections for a transport lock. The eyelets, hooks and pins can also be used to secure the transport. Usually, the further transport protection is done with straps that are posted on the eyelets, hooks or pins.

The containers are used to transport accessories for the cargo. For example, special angles, rails, seals, screws, dowels, etc. are usually required for the installation of glass panels. These parts must be supplied at least during transport to the end user or to the contractor commissioned by the end user. The containers can be positioned anywhere on the packaging.

The connecting means serve, for example, to connect several packages together. Preferably, a connection takes place on all packaging parts, which are opposed by grooves.

The various packages can be arranged so that at least one connection always takes place at the lower packaging sections and at one respective vertical packaging section.

When strapping a band around the provided with edge protection cargo, such as the glass, wrapped around. Then the band is tensioned with a tensioning device. The tension presses the edge protection sections against the edges to be protected. After clamping, the band is secured in the clamping position. This can be done by means of clips, sleeves, seals or by welding.

During the tensioning process, the tape is pulled off a roll. After securing, the band consumed by the strapping is separated from the rest of the band of the roll.

The band can be made of plastic or steel. There are plastic tapes made of different materials known, for example, polyester, PP, PET available for strapping. In any case, the band must withstand the occurring clamping forces. For this purpose, especially plastic textile bands such as thread structure bands, tape fabrics and composite tapes are suitable.

The strapping device usually has corrugated tension rollers with which captured the band ends to be pulled together and pulled against each other until a desired voltage is reached. In order to keep the strip tension for the duration of the transport, only plastics come into question, which show only negligible creep effects and / or by a Nachbehandlung, for example by permanent stretching, only negligible creep show. Steel bands show no noticeable creep effects. The creep effects describes a deformation of the plastic under high continuous load.

With the sleeves, clamps and seals the band ends are pressed against each other permanently. This may already be sufficient for the locking of the band ends. In addition, it is known, for example, steel strips in addition to hold that the steel strips are cut in front of and behind the brackets, sleeves and seals and bent out at the interfaces. Alternatively, the sleeves and staples may be corrugated with the ribbon ends in which the corrugations are transverse to the longitudinal direction of the ribbon. The curl reinforces the hold of the sleeves and brackets pressed around the ends of the band.

Welding is a joining technique which is preferably used for plastic tapes.

Optionally, the transport aids (even when using rollers) are formed at least in two parts, wherein the one part is held with the strapping and forms the connection described above for the other part of the transport aid. In this case, the part forming the connection may be a sleeve or seal or be connected to a sleeve or seal, which is placed on the strapping tape. For the positioning of this sleeve or seal is favorable when the sleeve or seal is laterally slotted and can be pushed laterally after positioning of the strapping before its final tension on the strapping. The sleeve or seal is preferably pressed onto the strapping band and thus brought to rest on the strapping band. In addition, it is advantageous if a funnel-shaped guide is provided at the slit of the sleeve or seal and when the sleeve engages behind the strap after pushing immediately. The funnel shape facilitates pushing on. The grip behind prevents falling down. If the sleeve also clamps on the strapping, the sleeve remains in the selected position or slipping is excluded.

Alternatively, provided for the transport aids on the strapping pods or seals can also be attached to a suitable point of the strapping when making the strapping with. This makes the entrainment of tools unnecessary for a later attachment of sleeves and seals.

The adhesion of the sleeves and seals on the strapping band depends on the pressing pressure and the friction values of the contact surfaces. The advantage is therefore roughened contact surfaces. Optionally, claws may be provided on the sleeves and seals.

Also, handles and tab may be advantageous, which are provided on the side edge protection at a distance from the upper end.

Optionally, a handle or eye on the strapping be clamped, the clamping with increasing weight of the protected cargo, for example, the glass, and packaging is getting stronger. Such a clamping arises for example by handles / eyelets, which also form a lever arm of a two-armed lever, the other lever arm presses against the strapping. These levers are self-clamping due to the explained mechanism. This mechanism can also be used when the handles and grommets are pushed into a groove as explained above. The friction between plastic tongue and groove made of plastic foam is so great that a jamming of the spring in the groove occurs.

In another variant, the terminals or sleeves are glued or welded to the strapping or connected in the same manner as in the connection of the band ends with the strapping.

The grips / grommets can also provide transport assistance without the sleeves and fittings described above when they include the strapping band at the desired location, for example with two fingers / jaws, so that pivotal movement of the gripper / sleeve upwardly causes distortion of the strapping band and Clamp the handle / eyelet on the strapping band leads.

Where additional reinforcing corners are provided on the package which are placed over the corners of the package, it may be advantageous to form and position these additional reinforcing corners, such as the sleeves or seals described above, on the strap.

The edge protection according to the invention can also be designed so that at the same time a plurality of disc-shaped transport goods (for example glass panes) can be transported side by side.

Optionally, the edge protector is provided with a plurality of recesses which are parallel to each other, as for example in the DE 1953181 is described.

Preferably, it is provided that the individual packaging can be connected to other packaging, so that a space-saving transport is possible. The connection can - as stated above - done for example with tongue and groove. Conveniently are recesses with dovetailed cross-section. Preferably, recesses are provided in each package, so that the connection can be made with corresponding springs, which engage with one side in a recess and with the other side in the other recess.

Advantageously, the recesses can also be used for other tasks, for example for connection to other profiles for thickening the compliance material.

It is advantageous if the edge protection according to the invention alone forms the packaging for glass and other packaged goods.

In the above-mentioned rough construction operation, it may also be necessary to supplement the edge protection by protecting the packaged goods in the space enclosed by the edge protection. This applies, for example, to surface-sensitive material.

In order to prevent scratching of the outer surfaces of the transported goods, for example of the glass, the space at the transported goods, which is enclosed by the protruding edge protection, for example, wholly or partially filled with cardboard or cardboard. In particular, corrugated board is offered in considerable thicknesses on the market, so that the space can be easily filled with single-ply or multi-ply corrugated board. As far as the room is large or the cardboard / cardboard insert should even protrude from the edge protection, is preferably a honeycomb insert made of cardboard or paperboard / corrugated cardboard application.

The honeycomb cardboard / paperboard construction has a very advantageous protective effect in all directions compared to other cardboard / paperboard constructions. Among the various protective effects is a good scratch protection.

Cardboard / cardboard is a very economical protection for the glass and the like cargo.

If the cardboard / paperboard does not meet the requirements of the cargo, it is initially possible to arrange a layer of plastic foam between the cardboard / cardboard layer and the item to be transported. In this case, the plastic foam may have the same texture as that provided for the edge protection plastic foam. The cardboard alone and / or with other protection can fill the space enclosed by the edge protection according to the invention on the pane. Other types of protection may include air cushions. The air cushions may also fill the space enclosed by the edge protection according to the invention alone and / or with cardboard or with other protection for the packaged goods.

Optionally, the space filled with cardboard or other materials on both sides of the packaged goods is closed with protective plates.

The protective plates can overlap the packaging or be embedded in the space enclosed by the packaging. The protective plates form a stiffener which may replace the stiffening struts proposed elsewhere or may be used in addition to the stiffening struts.

The attachment of the protective plates can be done in any way.

Preferably, a releasable attachment is provided which does not hinder the reuse of the packaging. Alternatively, the protective plates are held by means of claws or hooks on the packaging. These jaws or hooks, like the transport aids explained above, can grip into the grooves of the packaging. If all sections of the package are provided with such grooves, the claws or hooks may include the protective plate on all four sides, so that the protective plates do not come off the packaging even under normal transport load.

For the attachment of the protective plates, the claws or hooks are pushed into the grooves and at the same time over the protective plates. To release the protective plates, the claws or hooks are pulled out of the grooves.

Optionally, the entire cargo is wrapped on the way in a plastic foam.

For small batches, the wrapping is made up of different parts to avoid the cost of molds that allow the wrapping to be achieved in a single operation.

As soon as large series are foreseeable, the "wrapping in one operation" can be promoted. Preferably, this is started with the wrapping in particle foam. For wrapping in particle foam must have a correspondingly large shape be procured. This form is also called a tool. The transported material is positioned in the open mold, so that after closing the mold, the foam particles flowing during the filling of the mold into the mold cavity surround the transported goods on all sides. Subsequently, the mold is subjected to superheated steam, so that the foam particles soften on the outer surfaces and at least doughy and weld together. After sufficient cooling, the mold is opened and the wrapped cargo taken out.

Preferably, the plastic foam is then reinforced in the region of the edges of the cargo, for example of the glass, in the form described above.

Preferably, the transported goods are enclosed together with the packaging with a shrink film. These are films which shrink strongly under the effect of heat. The shrink films usually consist of a mixture of polyethylene and polypropylene. The films are often wrapped around the packaged goods. The films can also be processed into hoses or sacks and slipped over the packaged goods. The heat can be brought by means of hot air or by means of heating gas to the shrink film in order to set the shrinking in motion. Series products are preferably fed into a tunnel furnace and heated on the way.

The above-mentioned transport aids or their connections are preferably recessed from the shrink film. This can already be done with the wrapping with foil. It can also be provided recesses for the transport aids in the film tubes and film bags for the transport aids or their connections.

It is also possible to incorporate recesses in the film only when the connections for the transport aids must be accessible.

The packaged according to the invention transported goods, for example, a glass intended for construction sites, must be moved to the site. A distinction must be made between slices of smaller size and correspondingly low weight, which can be manually unloaded and transported by one or more builders and transported in situ, and slices of particular size and weight, which must be moved by machine.

In any case, the handling of the panes may be facilitated by transport aids such as handles and / or loops and / or eyes and / or hooks and / or connecting means and / or feet on the edge protector. The transport aids can be provided permanently or for the duration of the transport to the edge protection. In a permanent arrangement, a corresponding attachment of the transport aids can be done on the edge protection. For temporary attachment releasable fastening means are provided.

It is advantageous if the edge protection is claimed with the transport aids as possible only on train and as little as possible to bending.

This is achieved by the transport aids attacking the side edge protection.

In addition, it is advantageous to provide the lower edge protection with forklift feet. Forklift feet are known on pallets. Pallets have at the bottom forklift feet made of wood in the form of pieces of timber. The forklift feet steer a fork-lift truck, which engages under the pallet with its fork in order to lift it, to transport it to another location and to put it down there again. The same applies to pallet trucks, which are equipped with a fork like a forklift and are designed to move pallets. However, the trucks are only for transport at short distances and are not suitable for stacking. The stroke of the lift truck only serves to produce necessary for the process ground clearance of the packaged goods.

The pallet trucks are usually moved by hand. As far as in the following forklift are addressed, that includes .the pallet truck.

The forklift feet ensure a central attack of the forklift / lift truck on the goods to be transported and prevent lateral movement of the pallet during movement with the forklift. This is particularly important for the cornering of the truck / lift truck.

The stacker feet may be smaller in relation to normal pallets. However, a reduction in the forklift feet is omitted, if it is to be feared that the fork of the forklift / pallet truck no longer fits between the forklift feet. Furthermore, the stacker feet are designed so thick that the truck can go under the edge protection with his fork and can lift the cargo together with the package. The stacker feet can also be considered as transport aids. It is also an attachment of the forklift feet on the strapping with the help of sleeves and seals possible, as provided in the previously explained transport aids.

Optionally, the stacker feet are integrated into the package protector, even more preferably integrated into a package section.

The transport aids can be permanently or detachably provided at various points of the package. In a permanent arrangement individual packing sections may be formed in one part at the same time as desired transport aids or be permanently connected to the transport aids. So lower packaging sections can also have formations that serve as feet or Staplerfüße. The transport aids are preferably detachably mounted in order to reduce the number of transport aids required for all packaging. For this purpose, the transport aids can be posted to connections with which the packaging is provided. The terminals may for example be formed by projections and / or recesses in the package. The transport aids can engage the projections and / or engage in the recesses.

Preferably, grooves are provided in the packaging and engage the transport aids with so-called springs in the grooves. No special requirements are placed on the grooves when the grooves are arranged on opposite sides. As grooves then already low depressions and as feathers low surveys. In principle, the depressions (grooves) can also be provided in the transport aids and the elevations (springs) on the packaging. The required effort is higher than the other way around. In addition, the package can then be damaged at the surveys easier than depressions.

More is to be considered in the question of grooves / springs, if the transport aids should only engage in one groove. The transport aids must then be secured against falling out, against tipping and against unforeseen slippage in the grooves. This can be achieved largely by the cross-sectional shape of the groove and springs. Favorable is a cross-sectional shape in the manner of a Schwalbenschanzpassung. Such cross-sectional shapes are characterized by undercuts in the grooves and undercuts on the springs, so that the springs engage with the projecting cross-sectional parts in the grooves in the undercuts. With such grooves and springs falling out as well as tilting is prevented.

The stability of the grooves and springs depends on the plastic foam. If desired, the stability can be changed by reinforcing the grooves / springs and / or the surrounding area. Reinforcement by choosing another plastic for the packaging is only possible within the scope of the given flexibility for the packaging. But even simple measures such as the rounding of corners / edges in and on the grooves and springs leads to a significant reinforcement. In addition, reinforcement can be achieved by the skinning and coating described above. For the transport aids can easily be selected a material that keeps up out of all load cases. Favorable are transport aids with low weight, for example made of aluminum.

Slipping of the transport aids in the grooves is prevented by clamping.

For this purpose clamping devices can be provided. Simple clamping devices are for example wedges. It can also be used more expensive clamping devices. The transport aids can also be designed as clamping devices at the same time.

For the clamping, the friction conditions in the groove and on the springs, the movement play between groove and springs and the lever ratios prevail, resulting from the forces acting on transport aids and their distance from the tongue and groove connection of the transport aids of the package.

Economically advantageous is a self-locking the transport aids in the grooves or on the springs.

Depending on the circumstances, the transport aids in the groove or on the springs have self-locking. This is the case, for example, when plastic foam surfaces cut in the tongue and groove joint slide against one another.

Such transport aids wedged under a load that does not attack exactly centered to the central axis of the grooves. This can be easily achieved by choosing a suitable distance, are passed in the loads in the transport aids.

Wedges can also be used to clamp the transport aids Frequently, a crane or a forklift truck is available at the construction sites. The crane can be a construction crane or a crane on a truck. These devices can facilitate the unloading of the cargo. Sometimes the construction crane can also take over the transport to the respective rough construction days. As a rule, however, the goods to be transported must then be moved on by hand at least on the rough building floor. Frequently, the packaged goods must also be unloaded by hand and carried to the respective floor.

In particular, the transport by hand is at a construction site with a risk of damage connected. Previous transports repeatedly hit the construction sites or are put on too hard.

In the case of the packaging according to the invention, on the other hand, there is no longer any significant risk of damage. This can be seen in the case studies described above. If a cargo such fall tests survives damage-free, then the packaged according to the invention transported well over the usual tapping and hard putting on damage. Advantageously, glass can be additionally protected as transported goods by being lightly sanded at the edge.

Even a small cut in the circumference and the depth of the microcracks at the edges of the glass is sufficient.

Optionally, the stacker feet at the same time form a security for the packaging and the packaged goods against falling over by the stacker feet also form a support for the packaging and the packaged goods. The forklift feet can protrude laterally under the packaged goods and the packaging.

Optionally, supports are provided on the packaging, which protrude laterally from the packaged goods and the packaging.

The supports are preferably attached to the ends of the package. The attachment of the supports is facilitated by grooves / depressions on the packaging, in which the supports can engage with springs / protrusions.

The object of the invention has been found to simplify the packaging. This is achieved with the features of the current claims.

In this case, the invention would also appeal to those people who have to cope only occasional disc transport or only to a small extent disc transport. These people have very limited manual skills.

The invention seeks to provide these persons with easy-to-use, prefabricated packages that are used in place to package a disk. After use, the package should be returned to reuse the package, if necessary after conditioning.

Prefabrication of the packaging includes packaging adapted to the disc intended for shipment and delivered in such a way that manual activity in the packaging is no longer required.

The adaptation to the intended for transport disc is done in small quantities by using standard modules / sections as compliance elements, reinforcement profiles and use of fitting pieces. For larger quantities, the molded parts can arise as special components with a selected length, so that fittings are unnecessary.

The reinforcement profiles have a cross-module / cross-section length.

The standard modules / sections are preferably moldings made from foam particles. This is done by filling the foam particles into a mold and steaming the foam particles in the mold until the surface of the foam particles has melted and the foam particles are welded together under pressure. The resulting moldings are removed from the mold after adequate cooling. The moldings have substantially completely the same dimensions.

To adapt to the edge lengths of a disk provided for transport as many complete moldings on a reinforcing profile, preferably on a wooden profile, pushed as possible. Two reinforcing profiles are adapted to the longitudinal side of the packaging with a rectangular pane format. Two other reinforcing profiles are adapted to the narrow side of the packaging. The adaptation depends on the design of the packaging corners.

In the case of packaging corners with blunt-ended longitudinal sides and narrow sides, the reinforcing profiles preferably protrude beyond the pane corner at one end. The mold parts which surround the sections of compliance material preferably terminate flush with the reinforcement profile and, like the reinforcement profile on the relevant window corner, protrude beyond this corner.

The moldings, butt also between the corners.

In packaging corners with mitered ends of the long sides and narrow sides, the reinforcing profiles preferably protrude beyond the disc corners at both ends. Preferably, this also applies to the moldings which surround the sections of compliance material. The moldings are then mitred.

Between the mitred corners, the mold parts butt against each other.

Even more preferably found at the corners of the packaging corner pieces application. It is advantageous to make the corner pieces in the same way as the moldings for the other sections of compliance material. Of course, the associated forms differ accordingly.

When using corner pieces, the reinforcing profiles engage in the corner pieces. The corner pieces have strength advantages and manufacturing advantages. The corner pieces also form connectors for the long sides and narrow sides of the packaging. The manufacturing advantage is that the other sections / moldings that form the long sides and narrow sides can butt against the corner pieces.

The corner pieces form angles whose free legs (measured from the slice corner) may have a length of optionally 10 to 200mm, preferably 50 to 175mm, more preferably 75 to 150mm and most preferably 100mm to 125mm.

Optionally, so many moldings are arranged on the reinforcing profile that the moldings butt against the free legs of the corner pieces.

With mold part lengths, which are predetermined by the shape, it is often to be expected with changing dimensions of the slices to be transported that fitting pieces are required because a gap remains for which a molded part is too long or too short. Then a molded part is shortened or lengthened to accommodate the gap. The shortened or extended molded part is referred to as a fitting piece.

By prefabrication of the long sides and narrow sides for a designated transport disc, the user will be supplied packaging parts that are only to put together around the glass.

The delivery of the packaging parts is preferably carried out in a space-saving arrangement of the packaging part in a carton.

A space-saving arrangement is created by parallel arrangement of the described packaging parts.

Preferably, the longitudinal sides of the packaging are at the same time provided with corner pieces and arranged so that in parallel arrangement of the narrow sides between the longitudinal sides, the corner pieces of a longitudinal side with their free legs relative to the free legs of the other longitudinal side.

This creates a very space-saving arrangement.

Advantageously, the space-saving arrangement of the packaging parts is used in the shipment to the place of use by means of a carton, which consists of two in one another or one above the other sliding parts. The one cardboard part has a trough-like shape of the other cardboard part is hood-like, both cardboard parts have horizontal side walls vertical arrangement.

In the space-saving arrangement, the cardboard parts are pushed far into each other. This facilitates handling and can reduce transport costs.

To package the disc, the cardboard is opened by lifting a cardboard part. Subsequently, the upper-lying longitudinal side of the package is removed. The other longitudinal side remains at the bottom of the box.

The narrow sides located above the lower longitudinal side are erected and inserted with their projecting end of the reinforcing profile into the corner pieces, which are pre-mounted on the lower longitudinal side of the packaging.

The insertion takes place inside the carton so that the narrow sides are supported by the carton. According to the invention, this is used when inserting the disc in the space between the narrow sides, which are provided for insertion of the disc with the recesses described above.

The same recess is found in the long sides.

After complete insertion of the disc, the upper longitudinal side is placed on the disc and connected to the narrow sides. The connection is made by penetrating the upwardly projecting reinforcing profiles into the corner pieces preassembled on the upper longitudinal side.

After complete assembly of the packaging, the box is closed again. For this purpose, the previously lifted cardboard part is pushed back over the other cardboard part or both cardboard parts are pushed into each other. The cardboard parts are but pushed into each other less than in mere, space-saving transport of the packaging, because the packaging with the disc occupies much more space than without the disc.

Preferably, the two cardboard parts are connected to each other before shipment with tape. The compound is preferable tension-free, in any case, a tension of the cardboard parts is kept within the elastic range, if damage to the carton is to be prevented by the adhesive tape.

Nevertheless, the non-strapped packaging described above will safely encase the disc when the disc is carefully transported with the package. This is the case, for example, with a trained parcel service. In addition, parcel services usually do not provide in harsh environments, such as is regularly given on construction sites, for example.

For the parcel services a limited weight of disc and packaging is an advantage. Preferably, at most a weight of 50kg, more preferably a weight of at most 40kg and most preferably a weight of at most 30kg is provided.

With these weight limits and the specific weight of glass panes as well as with the package-by-layer transport of glass panes with a common packaging, dimensional limits result at the same time.

Irrespective of this, limiting the dimensions of the packaging according to the invention without strapping is also advantageous if only one slice is being transported. The smaller the dimensions, the easier it is to handle the discs for a parcel service. The dimensional limit is preferably at longitudinal dimensions of at most 2.5m, more preferably at most 2m and most preferably at most 1.5m. In addition, it should be taken into account that a large longitudinal dimension with great dimensions for the narrow side makes handling considerably more difficult if at the same time transport aids are not provided on the cardboard. Such transport aids are for example handles, grommets, loops and the like, as described in the PCT / EP2013 / 2697 are described.

Unlike in the PCT / EP2013 / 2697 described, but another connection of the transport aids is provided to leave the box undamaged. Preferably, the transport aids are glued to the carton. For this purpose, self-adhesive surfaces are optionally provided on the cardboard and / or on the transport aids. The adhesive is covered before use, for example with paper that is siliconized. It is advantageous if the adhesive surface on the cardboard is treated so that sufficient adhesion of an adhesive is ensured. This can be achieved with an at least partial coating of the cardboard with a suitable material. The layer may be, for example, a film or obtained by spraying or painting on material.

It is also advantageous if the transport aid is glued to the cardboard via a tape. The band makes it possible to bring about a bonding under the cardboard underside and nevertheless to arrange a handle at a comfortable grip height. When glued to the carton at handle height, the carton would be unfavorably loaded with pull-out forces.

The further use of the carton for wrapping the package when it is shipped has the advantage that the carton can be used to return the packaging after reaching the destination and after unpacking the disc.

In the drawing, various known packaging from the PCT / EP2013 / 2697 and embodiments of the invention shown.

The 1 and 2 show a laminated glass pane 1, which are included at the edge of four edge protection profiles 2, 3, 4, 5.

All profiles 2,3,4,5 consist of XPS foam (extruded polystyrene foam), in other embodiments of other foam) with a density of 25 kg / cubic meter. All profiles 2,3,4,5 have the same cross section.

In addition, the profiles 2 and 4 have the same length. The same applies to the profiles 3 and 5. The cross section of the profiles 2,3,4,5 is off 1 and 3 seen.

The profiles 2,3,4,5 are mitred at the ends.

The profile cross section is in 3 shown. The profile cross-section is basically rectangular with dimensions of 130mm × 200mm. On one narrow side, a recess 6 with a width of 23 mm and a depth of 50 mm is provided, in which the laminated glass pane 1 is received. On the opposite narrow side of a recess 7 is provided with a width of 60mm and a depth of 5mm, which is intended for a strapping.

Inside the profile two recesses 8 and 9 are provided with cross-sectional dimensions of 25mm × 50mm, which are intended to accommodate wooden strips 10.

In the exemplary embodiment, the XPS foam of the profile forms a compliance material. The wooden strips form a reinforcing material for the compliance material. By using several wooden strips with intermediate foam a special resistance of the edge protection against the glass transport particularly dreaded shock and shock loads generated.

In the exemplary embodiment, the profile is composed of three parts, not shown. In the unconnected state of the three parts run two parting lines through the recesses 8 and 9, parallel to the narrow sides.

The three parts are cut from commercially available XPS foam boards and assembled on the surface, so that the recesses 6 and 7 and further recesses arise, which form the recesses 8 and 9 after joining all the parts together.

The cutting operations are done by sawing.

The recesses are milled in the embodiment.

When joining, the parts are glued hot. The hot glue is applied with suitable glue guns.

In other embodiments, the parts are welded. During welding, the welding surfaces are heated and the parts are then pressed together. The necessary heat may be applied with a hot air blower (in other embodiments by contact with a heat shield or by means of another object having a corresponding heated surface with which the weld surfaces are brought into contact).

After the market introduction of the edge protection according to the invention then the desired number of pieces by (in relation to the cross section) integral extrusion of the profile or by injection molding or by moldings made of particle foam can be taken into account. For extruding extruder with extrusion nozzles are required, which are modeled on the profile cross section and carry the foam in a forming calibrator.

With the extrusion of a profile, which show all cross-sectional dimensions of the desired profiles, the above-described machining operations are at least partially dispensable.

The illustrated profiles 2, 3, 4, 5 are pressed against the edge of the glass pane 1 by an unillustrated strapping band (in other embodiments by a tension band or a tension belt). The strapping band is a plastic band in the embodiment. The strapping is removed from the strapping machine from a roll and guided around the outside of the profiles 2,3,4,5. This happens first by hand. For larger quantities a strapping device with automatic tape feed or automatic Umumungsbandes around the profiles 2,3,4,5 is provided.

The strapping device is available in various embodiments. Initially, a simple hand-operated device for tensioning the strapping band can be used. With appropriate quantities, an electrical strapping machine with automatic control instead of the hand-operated device can be used.

After clamping takes place in the embodiment, a welding of the two ends of the plastic strapping. In this case, a heating sword is briefly guided between the two ends of the strapping. The heating blade causes the contact surfaces of the two ends of the strapping band to melt for a short time, so that at the appropriate pressure, a welding immediately occurs, without there being any appreciable weakening of the strapping band. By immediately cooling the weld, the weld is immediately given sufficient strength.

By strapping the profiles 2,3,4,5 are held together in the illustrated form, without the need for further action.

In another embodiment, a reinforcement / corner protection is provided at the corners. The reinforcement / corner protection is formed by caps which are placed over the corners before the strapping takes place. Such caps are commercially available. Such caps are offered as plastic angles or metal angles. The automatic systems set the caps automatically, the function of such systems depends on the use of the caps on which the systems are designed. As long as it lacks the product lines, which justify automatic strapping, strapping by hand is recommended. When strapping by hand, the positioning of the caps is a problem unless the caps are held in place by the strapping. It is advantageous to bring / hold the caps with a self-adhesive strip adhesive on both sides, as long as this is not done by the strapping.

For strapping by hand, various commercially available devices are available, from very simple design to sophisticated design. The profiles 2, 3, 4, 5 form an edge protector projecting approximately 53.5 mm transversely to the plane of the glass pane. In the enclosed space a layer of cardboard 11 is provided with a thickness of 50mm on each side. In addition, between the cardboard 11 and the disc 1, a position not shown soft plastic foam made of polyethylene of 1,5mm thickness.

After strapping, the glass sheet, together with its edge protection and the lateral cardboard layers, is shrink-wrapped.

The shrink film leaves the bottom partially free, so that forklift feet 20 can be mounted there. The forklift feet serve as a transport aid for positioning the fork of a forklift, which is used for loading and / or unloading.

The edge protection 107 to 4 consists of polystyrene foam with a density of 30 kg per cubic meter. The cross-sectional width is 130mm, the height 160mm. In the middle is an opening 100 provided by 24mm × 48mm. The opening serves to receive a roof batten as a reinforcing profile. Further, four grooves 101,102,103 and 104 are provided on the circumference. The four grooves have a dovetail-shaped cross-section. The groove 101 has a width of 60mm at the foot, a depth of 60mm and an opening width of 50 at the top.

The groove 101 serves to receive a similar insert, with which the glass pane is covered at the edge. On the opposite side is a recess 102 intended. In the initially described edge protection, the recess serves 102 for guiding and securing a strapping band.

In the exemplary embodiment, the groove / recess 102 a depth of 20mm, in the deepest a width of 50mm and at the opening a width of 40mm. To 4 has the groove / recess 102 additional tasks. In the groove, a housing can be inserted, in which a roller is rotatably supported. Additionally or alternatively, in the groove 102 two stacker feet are inserted, which are arranged at the distance of the forks of the stacker centrally under the glass sheet under the packaging to facilitate the transport of the glass sheet by means of a stacker, for example, for loading or unloading a vehicle.

In addition, the groove / recess 102 be used to the profile a dash-dotted flat profile 105 to attach from the same plastic foam.

A similar flat profile can also on the other two sides with the grooves / recesses 103 and 104 be attached. By attaching flat profiles creates more compliance material with a correspondingly changed / increased damping behavior, which takes into account the burden of heavy glass panes.

The grooves / recesses 103 and 104 have a depth of 15mm, in the deepest a width of 40mm and at the opening a width of 30mm.

An essential further task of the grooves / recesses 103 and 104 is the connection with other packaging / edge protection, one of which is packaging 106 dash-dotted lines in the neckline is shown.

The packaging / edge protection 106 has the same groove / recess as the packaging / edge protection / compliance profile 107 , The connection can be made with the help of a so-called spring 108 be achieved. The feather 108 is formed by a profile bar having in cross-section two sides / ends, which the grooves / recesses in the packaging / edge protection 106 and 107 are adapted so that a firm connection is formed.

By the spring 108 formed connection technology, a variety of packaging with enclosed packaging material can be connected together to form a transportable block. The resulting block can be designed within wide limits with any width, so that transport areas in the width can be optimally utilized.

In addition, the blocks can be designed in height within a wide range, so that transport volume can be optimally utilized in height. Here, instead of the flat profile 105 another packaging put on and by means of the spring 108 connected.

Finally, the block can also be designed arbitrarily in length within wide limits. Here are the successively arranged packages with the enclosed cargo through the springs 108 connected with each other.

This opens up significant advantages for container transport or truck transport and for such transport by utilizing the transport volume.

In this case, packaging of different sizes can be interconnected. This can be done directly via springs 108 take place when the associated grooves in the various packages are exactly opposite each other. However, if the grooves are not opposed to each other, a connection may still be made via the grooves 108 respectively. For this purpose, an intermediate piece is provided. The intermediate piece grooves are incorporated in appropriate height or distance been, so the springs 108 which can connect a packaging from one side and the other packaging from the other side with the intermediate piece.

Alternatively, intermediate pieces may be provided which are adapted to the different sizes of the packages to be joined. That is, these spacers correspond to the previously described intermediate pieces with the springs provided on both sides 108 but are integral with the springs.

To 4 the connection of two packagings with packaged goods takes place with a separate spring. In the embodiment according to 4 only one connection is shown on the underside of the packaging circulating on the glass pane. This is usually sufficient because the packages are handled individually by a vehicle after unloading. The particular advantages of the connection therefore arise when transporting several juxtaposed packages with a vehicle. Then the load securing is much easier. For example, load securing may be limited to lashing the packages together at the top. In other embodiments, a need for more security is taken into account that the juxtaposed packages are connected to each other at least at the top of the package by such a connection. This connection leads to a very stable / resistant overall packaging. Such a demand arises when the transport is not carried out with trucks but with vans with permissible gross weight of less than 7.5 tons. With such transporters are usually handled by hand (without lifting) manageable transports, because the transporters are much faster than truck transports. Experience has shown that the load securing in such vans is extremely inadequate despite the corresponding traffic regulations. For such transports, an additional connection of the juxtaposed packages at their top is advantageous.

As far as there is more need for a connection of the juxtaposed packages, such a connection is also provided on the two sides which connect the top and bottom of the package.

The 5 to 13 show profiles / molded parts made of EPP. It is made of polypropylene particle foam, consisting of foam particles, which steamed like the foam particles of polystyrene in molds and welded together to form parts. However, polypropylene is much more resistant to wear than polystyrene. In addition, a greater strength at the same density. Therefore, these profiles are particularly suitable for multiple use.

In the embodiment according to 5 to 13 have the profiles / moldings a density of 40 kg per cubic meter; in other embodiments, a lower or a higher density.

For heavier glass panes, the volume weight can also be 60 kg per cubic meter.

5 and 6 show moldings 271 that with a recess 267 are provided for receiving a glass edge / glass.

The moldings 271 are moreover with lateral recesses 266 and on the back with exception 266 Mistake. All recesses 266 have a dovetail-shaped cross-section.

These recesses 266 allow side-by-side packaging of the same profiles / molded parts 271 connect to. For this purpose, profile bars in the adjacent recesses 266 pushed, like the profile bars 108 of the 4 in cross section, the adjacent recesses 266 depict. In addition, the recesses allow 266 a compound of the moldings 271 with transport aids like those in the PCT / EP2013 / 2697 are described, as well as the connection with any other parts, the one of the recess 266 have adapted profile. The recess 266 on the back of the moldings 271 may also provide guidance and support for strapping or the like tensioning devices disclosed in the PCT / EP2013 / 2697 are described.

at 265 is the molding 271 constricted.

As a result, those are between the constrictions 265 and the recess 267 remaining material webs yielding. This facilitates the insertion of the glass in the recesses provided for it 267 the packaging.

The moldings 271 point approximately in the middle to the bottom of the recesses 266 and 267 a longitudinally continuous opening 270 on. The opening is intended for a reinforcement profile. In the exemplary embodiment is a wooden profile. In other embodiments reinforcing profiles of other material are provided.

The moldings 271 are pushed to the formation of a desired packaging side (long side or narrow side) on the reinforcing profile / threaded until it with their faces lie together. In doing so, the molded part grip 271 with molded pimples 269 in recesses formed on the end side at the corresponding place 268 , As a result, the knobs contribute to the connection of the molded parts.

To 7 and 8th are corner pieces for rectangular glass panes at the corners of the packaging 171 provided between the moldings.

The corner pieces 171 are preferably made in the same way and from the same material as the moldings.

The corner pieces 171 own at the joint with the moldings 271 the same education as the moldings 271 at their joints. These include a recess 161 for receiving the glass panes and recesses 160 with the same dovetailed cross-section as the recesses 266 the molded parts 271 and with the same pimples 170 and recesses 169 like the moldings 271 ,

The corner piece 171 Incidentally, the shape of an angle with two legs, with the joint with the moldings 271 located at the free ends of the legs.

In contrast to conventional elbows is the corner piece 171 rounded at 167 on the outside and 162 on the inside. The outside curve facilitates the insertion of the packaging into a surrounding carton. The inside rounding increases the stability of the corner pieces 171 ,

The recesses 160 run independently of the rounding straight through the corner pieces.

In the manufacture of the packaging reinforcing profiles are cut to length depending on the dimensions of the glass sheet and molded parts 271 and corner pieces 171 as packaging together. In the embodiment, the moldings 271 and four corner pieces 171 if necessary pushed with fitting pieces on the reinforcement profiles. The fitting pieces are used when the length of a disc edge between the corner pieces without consideration of protruding nubs does not form an integer multiple of the length of the moldings. For example, if the portion of the disk edge lying between the corner pieces is a multiple of 5.7 of the length of the available moldings, the question of a 0.7-fold molding is solved with a fitting as a gap filler whose contact length with the glass edge is 0, 7 times an available molding is. That is, an available advantage is curtailed accordingly. At the moldings after 5 and 6 this is done by cutting out an example central part and by gluing the remaining parts. This leaves the nubs 269 and the depressions 268 receive. The resulting part is then the fitting piece.

For the cutting out of a part from an available molding, various methods come into question. These include mechanical processes such as sawing as well as thermal processes such as cutting with a heating wire. When cutting with heating wire, the behavior of the plastic foam is used when exposed to heat. When the heat is high enough, the foam collapses, causing a gap to form in the foam in front of a highly heated wire as the wire is moved against the foam.

For gluing the remaining parts after cutting out a hot melt adhesive is preferably used. The hot melt is sprayed in the embodiment.

Instead of the bond can also find a welding application.

In the exemplary embodiment, the method is limited to cutting out pieces with a length of 0.3 times the length of an available molded part. In the case of all shorter lengths, a molded part is produced in the exemplary embodiment that has a greater length than an available molded part. For example, a fitting of 0.2 times the length of an available molding is not produced but a fitting of 1.2 times the length is produced. This happens, for example, by central division of an available molding and insertion of an intermediate piece. The intermediate piece is also obtained from available moldings. Preferably, the division is carried out by one of the cutting methods described above and the subsequent insertion of the intermediate piece by gluing.

The limit to when a fitting is made by shortening or extending an existing molding depends on the length of the molding. For large lengths, a reduction of an existing molding to 0.2 times is possible. For small lengths, a cut to 0.5 times may be disadvantageous.

The above-described methods for producing fitting pieces have advantages with small package numbers. For larger quantities, the procurement of special forms of advantage, with which molded parts are produced, in which the edge length is always an integer multiple of the length of the resulting moldings. Although the cost of the mold is much higher than the cost of cutting equipment, Parts and gluing or welding, but the labor required for the production is reduced considerably.

In the exemplary embodiment, packaging pages are prepared with the above-described molded parts and corner pieces and optionally fitting pieces as well as the reinforcing profiles. Each longitudinal side is connected to two corner pieces. The connection is effected by the reinforcing profile and the knobs. The reinforcing profile engages through all the molded parts into the corner pieces. At the same time, the moldings are connected to each other and with the corner pieces through the knobs, which engage in the recesses of the opposite moldings.

In other embodiments, the longitudinal sides are only connected to one corner piece or the long sides are not yet connected to the corner pieces or all fittings and optionally fittings and corner pieces and reinforcing profiles are supplied in individual parts.

In the exemplary embodiment, the prepared long sides and narrow sides are shipped with a box to the site. The packaging pages are in the carton one above the other, so that a space-saving arrangement is created. This also applies to the embodiments with prepared longitudinal sides without corner pieces.

A carton is also provided for the delivery of individual parts.

At the same time, the free legs of the corner pieces are directed against each other on the long sides.

The long sides 55 and 56 The packaging consists of molded parts (possibly including fitting pieces) and corner pieces and reinforcing profiles. The moldings and corner pieces sit in the manner described above on the reinforcing profiles.

The narrow sides 57 and 58 also consist of molded parts, but are without corner pieces. The reinforcing profiles protrude with ends 59 in front of the moldings. The ends 59 are intended to grip during assembly of the packaging in the corner pieces on the long sides.

After opening the box 50 becomes the upper longitudinal side 56 the packaging lifted out of the box. The lower longitudinal side 55 the packaging remains in the cardboard part 52 , The narrow sides 57 and 58 be in the cardboard part 52 upright and with the protruding ends 59 the reinforcing profiles inserted into the corresponding openings of the corner pieces. At the same time, the above-described knob connection between the corner pieces and the narrow sides 57 and 58 ,

After the connection of the narrow sides 57 and 58 with the lower longitudinal side 55 become the narrow sides 57 and 58 supported in the carton by the carton. 11 shows the situation.

In the situation, the glass sheet to be packaged between the narrow sides 57 and 58 pushed into the recesses of the moldings, and indeed until the glass penetrates into the recess of the moldings of the lower longitudinal side. Thereafter, the upper longitudinal side 56 with the pre-assembled corner pieces on the inserted glass pane and with the corner pieces at the same time on the protruding ends 59 the narrow sides plugged.

Last is the upper cardboard part 51 again over the lower cardboard part 52 pushed and both cardboard parts are secured in the sliding position by an adhesive tape.

The box can thus be sent by parcel service and delivered to the recipient.

The 13 shows a different format packaging than the 10 and 11 ,

The glass pane to be packed has a much longer length than the narrow sides. As a result, the narrow sides can be arranged one behind the other, while the narrow sides after 10 had to be arranged one above the other to achieve the desired space-saving location between the long sides.

To 13 Both long sides are each made of eight identical moldings 300 and two corner pieces 302 put together. The narrow sides each consist of only four identical moldings 301 ,

It is also in 13 represented as the reinforcing profile 308 the lower longitudinal side in the associated corner pieces 302 engages, or as the reinforcing profile of the upper longitudinal side in the associated corner pieces 302 attacks.

The reinforcing profiles of the narrow sides are indicated by dashed lines at 304.

The way of unpacking the disc after reaching the destination is at the discretion of the recipient of the program.

After unpacking the glass, the packaging for the return can be equally space-saving introduced into the box as when transporting. The introduction of the packaging in the carton can be made for the return at will.

In the above-described embodiment with prepared longitudinal sides and narrow sides and in each case one corner piece on all prepared longitudinal sides and narrow sides of the packaging, a different mounting of the longitudinal sides and narrow sides of the packaging is provided. In this case, all parts are removed from the box and placed one after the other around the edges of the glass to be packaged. The packaging is finished with the glass pane placed in the box and the box closed to send the glass.
