Description

[0001] The invention relates to a method for coating the narrow surface of a panel element, in particular a furniture panel, wood-based panel, worktop, chipboard, lightweight panel, interior panel, door, fiber cement panel or the like, - wherein the narrow surface coating is carried out using edge band profiles which have a base layer consisting of B-material, for example recycled material, and - wherein preferably the base layer, as seen in the profile cross-section, is covered on its outer longitudinal side covering the narrow surface with an outer layer of the edge band profile made of a first, preferably polymeric A-material.

[0002] The invention further relates to a panel element, in particular a furniture panel, worktop, chipboard, lightweight panel, interior panel, door, fiber cement panel or the like, with a thickness D, comprising at least one edge band profile, with at least one base layer, wherein the base layer preferably covers an outer layer, both of which at least partially comprise a polymeric material, both of which have a width B3, B4 of 10 to 120 mm, preferably 15 to 100 mm.

[0003] These types of edge banding profiles have primarily been used for decorating or protecting the narrow surfaces / side edges of objects such as furniture panels, wood-based panels, chipboard, and the like. For this purpose, the edge banding profiles are, for example, fixed to the narrow surfaces / side edges of the objects to be decorated or protected.

[0004] Sustainability is playing an increasingly important role in the edge banding of panel elements. Therefore, efforts are being made to use as much filler material as possible in the corresponding edge banding profiles, derived from waste, returns, or similar materials – so-called B-material. However, this B-material does not meet the optical, chemical, or mechanical requirements for the surface of the panel's narrow edges and can therefore only be used in the interior of the applied edge banding profiles, where it is not visible from the outside.

[0005] As a rule, the edge band profiles have a vertical overhang compared to the narrow surfaces of the panels, meaning the edge band profiles are wider than the panel is thick.

[0006] The corresponding protrusions are usually removed from the edge banding edges by means of a machining milling process, so that a flush vertical finish with the panel is created.

[0007] This process has proven successful in practice; however, it generates large quantities of milled-off A-material as waste. This is where the invention comes in, aiming to significantly improve the application possibilities of B-material and reduce waste in the narrow-area coating of panel elements.

[0008] For example, EP 1163864 discloses a panel element, in particular a furniture panel, and a method for its manufacture. It describes how an edge banding profile / profile element can be fixed to wood-based materials via its functional layer by applying heat, for example, using laser technology. When fixing the edge banding profile / profile element to the narrow surfaces of panel elements, it is difficult to achieve a secure hold, especially for polymeric edge banding profiles / profile elements, with various materials.

[0009] Furthermore, DE 102010011545 A1 discloses a method for manufacturing a furniture panel and such a furniture panel. This furniture panel is designed such that the top side of a substrate made of wood or wood substitute is bonded to a clear or satin-finished plastic panel, the underside of the plastic panel is coated with a colored lacquer, the top side of the plastic panel is coated with a scratch-resistant clear lacquer, and the edges of the custom-cut furniture panel are covered with a so-called plastic edge in a glass-like appearance.The process for manufacturing a furniture panel is designed such that, in a first step, a translucent plastic panel is coated on the top side with a scratch-resistant clear lacquer, in a further step the plastic panel is coated on the underside with a colored lacquer, in a further step the plastic panel is bonded under pressure to a substrate made of wood or wood substitute, and in a further step after the adhesive has set the furniture panel is cut to size, whereby in a further process step the cut furniture panel is covered with a plastic edge in a glass look.

[0010] In current technology, the processing of edgeband profiles sometimes results in more than 20% waste.

[0011] This is where the invention comes in, which on the one hand leads to a reduction in waste in the existing manufacturing process and on the other hand is intended to improve the application possibilities of B-material in the narrow surface coating of panel elements.

[0012] The invention further aims to overcome the disadvantages of the prior art and to provide panel elements with edge band profiles that can be manufactured economically and with a significant reduction in waste, which on the one hand make it possible to achieve a high-quality optical impression and retain the previous functions from the prior art, and on the other hand include new functionalities, are halogen-free and can also be manufactured in a significantly more sustainable way.

[0013] According to the invention, this problem is solved by the features of claim 1. Further advantageous embodiments are described in the dependent claims.

[0014] It has surprisingly been shown that a method for narrow-surface coating of, preferably rectangular, panel elements, in particular furniture panels, wood-based panels, worktops, chipboard, lightweight panels, interior finishing panels, doors, fiber cement panels or the like, - wherein the narrow surface coating is carried out using edge band profiles which have a base layer consisting of B-material, for example recycled material, and - wherein preferably the base layer, as seen in the profile cross-section, is covered on its outer longitudinal side covering the narrow surface with an outer layer of the edge band profile made of a first, preferably polymeric A-material, characterized by - that the edge band profiles have a narrower width than the thickness D of the panel element, - that the edge band profiles are first attached to the narrow surfaces in such a way that the panel element protrudes at least on one side, forming recesses that are angular in cross-section, and - that the recesses along the edge of the plate element are then filled with a second, preferably polymeric, A-material, preferably by means of a melting process, solves this problem.

[0015] It is within the scope of the invention that after the edge band profile is attached and before the recesses and / or the corner recesses are filled with the various A-materials, the longitudinal edge sides of the edge band profiles and / or the recesses and / or the corner recesses are processed, for example by mechanical processing, in particular with a milling cutter, a scraper and the like.

[0016] It is further within the scope of the invention that, after the edge band profile has been attached and before the recesses and / or the corner recesses have been filled with the various A-materials, the longitudinal edge sides of the edge band profiles and / or the recesses and / or the corner recesses are machined, in particular with a milling cutter, a scraper and the like, whereby the volume of the recesses and / or the corner recesses in particular is increased.

[0017] Two embodiments are fundamentally within the scope of the invention.

[0018] According to one design variant, the base layer is covered with an outer layer. In this case, the B-material of the base layer is expediently made of a lower-quality material, e.g., recycled material. Since the base layer is covered on the outside by the outer layer in this case, the B-material does not affect the appearance of the panel element. In particular, the B-material in this variant differs from the A-material at least with regard to its quality.

[0019] In a second embodiment of the invention, the B-material is of such high quality that it meets the optical requirements for an edge banding profile. In this case, the B-material is, for example, virgin polymer material. In this variant, the B-material can also consist of a material that is subsequently referred to as A-materials. Overall, the method according to the invention can therefore also be used, in particular, with previously known edge banding profiles.

[0020] A fundamental advantage of the inventive method is that the milling of protruding edges of the edgeband profiles is replaced by a filling process with the second A-material in the corresponding edge areas of the panel element. This significantly reduces or even completely eliminates the generation of milling waste.

[0021] According to one embodiment of the invention, the plate element protrudes on both sides and the resulting recesses are filled accordingly on both sides of the plate element with the second A-material.

[0022] In another embodiment of the invention, the edge band profile is flush or at least substantially flush with the plate element on one side, so that the filling with the second A-material only takes place on the other side of the plate element.

[0023] A further advantage of the method is that the base layer on the side flush (or at least substantially flush) with the panel element is also covered on the edge side with the second A-material of the edge band profile, so that the surface edge of the panel element is also formed only of A-material in this area.

[0024] Another advantage of this method is that, viewed in the plane of the panel, the edge band profiles in the corner areas of the panel element are flush with it, forming corner recesses perpendicular to the panel plane, and these corner recesses are filled with the third A-material. This third A-material can differ from the second A-material, for example, in its flow behavior if the third A-material is applied perpendicularly. However, it is also within the scope of the invention that the third A-material is identical to the second A-material. In principle, the materials mentioned below for the second A-material can also be used for the third A-material.

[0025] Furthermore, within the scope of the invention, it is advantageously provided that the filling of the recesses and / or corner recesses is carried out by forming tools. The forming tools are designed such that the A-material to be filled is placed in a mold, cooled, and / or calibrated. In a further embodiment of the invention, it is advantageously provided that the filling of the recesses and / or corner recesses with a forming tool is carried out such that the A-material to be filled is melted and melted into the recesses and / or corner recesses.

[0026] It is within the scope of the invention that after filling the recesses and / or the corner recesses with the various A-materials, these surfaces are post-processed, for example, mechanical post-processing, in particular with a scraper, a milling cutter and the like.

[0027] B-material within the meaning of the invention is, for example, recycled material; however, it is also within the scope of the invention that B-material is, for example, a polymeric, in particular thermoplastic, paper-based, veneer-based, or wood-based material, and the like. As already explained above, B-material can also be identical to A-material in terms of its composition. As also already explained above, according to one embodiment, B-material, particularly if a separate outer layer is lacking, can also be non-recycled material, in particular virgin material.

[0028] Material A, as defined in the invention, is generally not recycled material, as it must meet high optical requirements. Material A is advantageously used in the form of non-recycled material, particularly virgin material, which is, for example, polymeric, especially thermoplastic, elastomeric (e.g., silicone-based), or thermosetting. In particular, the second material A can also consist of a silicone. Furthermore, the second material A can consist of several components; optionally, it can also be formulated as a filler, especially a plastic dispersion filler, a component filler, or as a putty, especially inorganic or organic putties, e.g., made of synthetic polymers and the like. Advantageously, the second and / or third material A has a paste-like consistency during processing and then hardens.The second and / or third A-material can be plastically deformable during its processing and cross-link physically and / or chemically and / or by radiation.

[0029] Another advantage of the method is that the filling with A-material is carried out by forming a sloping surface that fills the cross-section or a sloping, outwardly curved arc.

[0030] It has also surprisingly turned out that a panel element, furniture panel, wood-based panel, worktops, chipboard, lightweight panel, interior panel, doors, fiber cement panel and the like., with a thickness D, comprising at least one edge band profile, with at least one base layer, wherein the base layer is preferably covered by an outer layer, both of which at least partially comprise a polymeric material, both of which have a width B3, B4 of 10 to 120 mm, preferably 15 to 105 mm, is characterized in that the edge band profile has at least partially a lesser width B3, B4 than the thickness D of the plate element, that the edge band profile is arranged at least partially spaced from a top and / or a bottom of the plate element on at least one longitudinal edge side L1, L2, and that at least one separate profile element is arranged on the at least one longitudinal edge side L1, L2 of the edge band profile, solving this problem.

[0031] This advantageously makes it possible to provide panel elements with edge band profiles / profile elements that not only realize the previously known functional effects, for example against moisture or temperatures, but that the edge band profiles / profile elements in particular can be manufactured much more sustainably and are especially easy and fully recyclable.

[0032] Another advantage of the panel elements is that the material price of the edge banding profile / profile elements as well as their manufacturing costs are at a very low level, with at the same time better availability of the required raw materials, so that the edge banding profiles / profile elements used have a significantly lower “CO2 footprint” than those in the known state of the art.

[0033] An advantage of this panel element is that the edge band profile is arranged on at least one longitudinal edge side L1,L2, spaced at least partially from a top and / or a bottom surface of the panel element via at least one recess. This makes it possible to provide panel elements that are cost-effective, economical, and sustainable to manufacture.

[0034] A further advantage of the plate element is that at least one profile element is arranged in at least one recess.

[0035] It is also advantageous that at least one profile element is fixed in at least one recess.

[0036] This makes it possible to provide cost-effective and economically produced, sustainable panel elements, as it is possible to use several edge band profiles of the same dimensions for panel elements with different thicknesses.

[0037] Another advantage of the plate element is that the edge band profile has a width B3, B4 that is 0.2 to 25%, preferably 0.5 to 20%, smaller than the thickness D of the plate element on at least one longitudinal edge side L1,L2.

[0038] It is also advantageous that the edge banding profile is arranged at least 0.10 to 20 mm, preferably 0.15 to 10 mm, from the top and / or bottom of the panel element on at least one longitudinal edge side L1,L2. Panel elements can be provided in which the edge banding profiles used are also suitable for panel elements of different thicknesses.

[0039] A major advantage with regard to the sustainability of the panel elements is that the material of at least one base layer and / or the outer layer of the edge band profile and / or the profile element contains renewable raw materials of 0.01 to 100%, preferably 20 to 100%, particularly preferably 40 to 100%, as demonstrated by mass balance calculations, e.g., via ISCC.

[0040] It has also proven advantageous for the plate element to have a coating applied at least partially to at least one front face of the edge band profile and / or the profile element, pointing away from the narrow surface of the plate element, as well as to the top and / or bottom of the plate element. It is further advantageous that the coating has a thickness of 1 to 350 µm, preferably 2 to 300 µm, and particularly preferably 5 to 250 µm.

[0041] It is also advantageous that the coating on the front side, facing away from the narrow edge of the panel element, is designed as a co-extruded or post-co-extruded layer, as a paint application, or as a printed layer. This coating, whether designed as a paint application or a printed layer, can advantageously be realized, in particular, by so-called multi-color printing, digital printing, gravure printing, and the like. In this advantageous configuration, the intensity and feel of the edgeband profile's surface can be further optimized by the material, thickness, and shape of the coating.

[0042] The coating can advantageously contain renewable raw materials from 0.01 to 100%, preferably 20 to 100%, particularly preferably 40 to 100%.

[0043] All of this leads to an economical and cost-effective production of the panel elements with edge band profiles / profile elements, as well as further optimization possibilities, especially for the surface or the appearance of the edge band profiles / profile element.

[0044] A further advantage of the panel elements is that at least one cover layer with a thickness of 2 to 60 µm, preferably 5 to 30 µm, is arranged on the front side of the edge band profile / profile element. It has also proven advantageous for the cover layer on the front side to comprise at least one acrylic polymer and to have a maximum transmittance of 80% for visible light across its thickness, measured according to DIN EN ISO 13468-2:2006-07. The cover layer can advantageously contain renewable raw materials of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%.

[0045] In addition to an aesthetically pleasing top surface for the edge band profiles / profile element, mechanical protection is still possible, which, however, does not affect the appearance, in particular the optical structural effect of the edge band profiles / profile element.

[0046] A further advantage of the panel elements is that the material of at least one base layer and / or the material of the outer layer of the edgeband profile and / or the profile element has a Shore D hardness of at least 40 according to DIN EN ISO 868:2003-10. This ensures economical and cost-effective production and also makes it possible to adapt the material of the base layer and / or the outer layer to the specific requirements of the objects, such as the furniture to be edgebanded, and the like.

[0047] In a further advantageous embodiment of the edgeband profile, it has been shown that the reverse side of the base layer and / or the outer layer of the edgeband profile and / or the profile element is subjected to a surface treatment using a corona treatment, flame treatment, plasma treatment, silicatization process, or the like. This allows for an optimized bond between the edgeband profiles for a wide variety of material combinations.

[0048] In a further advantageous embodiment of the panel elements, it has been found that the material of the at least one base layer and / or the material of the outer layer of the edge banding profile and / or the profile element contains light- and / or radiation-absorbing additives in an amount of 0.01 to 5 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. In this embodiment of the edge banding profile / profile element, it can be optimally welded, for example on the narrow sides of furniture pieces, by laser welding processes known per se, through the targeted introduction of energy into the material of the at least one base layer and / or the material of the outer layer.

[0049] It has also proven advantageous that the material of the at least one base layer and / or the material of the outer layer of the edge banding profile and / or the profile element contains at least one additive, partially containing inorganic and / or organic pigments, in an amount of 0.01 to 5.0 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. This makes it possible to apply the edge banding profile / profile element cost-effectively and economically, for example, to the narrow sides of furniture, using all currently known radiation-activated methods.

[0050] It is also advantageous for the plate element that the material of the at least one base layer of the edge band profile and / or the profile element comprises at least one filler in 5 to 50 wt.%, preferably 10 to 45 wt.%, and particularly preferably 15 to 35 wt.%, based on its total weight. The filler is selected in particular from silicates, carbonates, phosphates, sulfates, sulfides, and the like. It is further advantageous for the filler to be selected from the group of layered silicates, as well as carbonates or sulfates of barium and calcium, and the like. In a particularly advantageous embodiment of the edge band profile / profile element, the filler of the at least one base layer comprises in particular barium sulfate, calcium sulfate, calcium carbonate, talc, and wollastonite. The fillers can advantageously comprise renewable raw materials in the proportion of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%.

[0051] A further advantage of the edgeband profile is that the filler in the base layer material of the edgeband profile / profile element has a mean particle size with a D50 value of 0.2 to 25 µm, preferably 0.5 to 15 µm, and particularly preferably 1 to 8 µm, according to DIN 66165-1:2016-08. It is also advantageous that the filler in the base layer material of the edgeband profile / profile element has a particle size with a D98 value of 15 µm, preferably less than 15 µm, and particularly preferably less than 10 µm, according to DIN 66165-1:2016-08.

[0052] The material of at least one base layer and / or the outer layer of the edge banding profile and / or the profile element is based on polyolefin, such as polypropylene (PP) or polyethylene (PE); a styrene-based polymer, such as polystyrene (PS) or styrene-butadiene copolymer with a predominant styrene content (SB) or acrylonitrile-styrene-acrylate copolymers (ASA) or acrylonitrile-butadiene-styrene copolymers (ABS) or styreneacrylonitrile (SAN); polybutylene terephthalate (PBT); polyethylene terephthalate (PET); polyoxymethylene (POM); polyamide (PA); polymethyl methacrylate (PMMA); polyphenylene oxide (PPO); polyetheretherketone (PEEK); polyphenylene sulfide (PPS); liquid crystal polymer (LCP); polyamide-imides (PAI); polyphenylsulfone (PPSU); polyaryletherketone (PAEK); polyacrylonitrile (PAN); polyetherketone (PEK); polyimide (PI); polyisobutene (PIB); polyphthalamide (PPA); polypyrrole (PPY); Polyurethane (PUR); polyvinyl alcohol (PVA);Polyvinyl acetate (PVAC), thermoplastic olefin-based polymers (TPE), and mixtures of at least two of these materials are based on these materials.

[0053] Furthermore, the plate element is advantageously designed such that the material of the at least one base layer and / or the outer layer of the edge band profile and / or the profile element contains at least one of the following additives: stabilizers to improve resistance to light exposure, UV radiation and weathering; stabilizers to improve thermal and thermo-oxidative resistance; stabilizers to improve hydrolytic resistance; stabilizers to improve acidolytic resistance; lubricants; demolding aids; color additives; crystallization-regulating substances and nucleating agents; flame retardants; impact modifiers; fillers and / or plasticizers.

[0054] The additives can advantageously comprise renewable raw materials of 0.01 to 100%, preferably 20 to 100%, particularly preferably 40 to 100%.

[0055] Thus, a panel element can be provided that is both economical and cost-effective to manufacture, but also realizes the functions of edgeband profiles / profile elements known from the state of the art, such as adhesion strength values, peel strength values, and water resistance.

[0056] A further advantage of the panel element is that the base layer and / or the outer layer of the edge banding profile and / or the profile element itself has a functional layer, at least in sections. In addition to economical and sustainable manufacturing, it is also possible to optimize the fixation of the edge banding profile / profile element to a panel element by varying the functional layer. This can be achieved, for example, by designing the functional layer as a so-called adhesion promoter layer, a so-called hot melt adhesive layer, or a polymeric functional layer.

[0057] Another preferred embodiment relates to a plate element according to one of the preceding embodiments, wherein the functional layer of the edge band profile and / or the profile element is based on a polymeric material, preferably polypropylene (PP), acrylonitrile butadiene styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polyethylene (PE), styrene-ethylene butadiene styrene block copolymer (SEBS), polyamide (PA), thermoplastic olefin-based elastomer (TPO), thermoplastic urethane-based elastomer (TPU), thermoplastic copolyester (TPC), styrene block copolymers (SBS, SEBS, SEPS, SEEPS and MBS), thermoplastic copolyamide (TPA) and the like. The polymeric material can advantageously comprise renewable raw materials of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%.This measure has the advantage that this material is readily available at low cost, easy to process, and also simple to chemically modify.

[0058] In a further preferred embodiment, the functional layer is designed as a thermoplastic functional layer, which makes it possible to fix an edge band profile / profile element according to the previously described embodiments without adhesive, i.e. without having to apply an additional so-called hot melt adhesive immediately before attaching it, and without a visible joint on a narrow side of a lightweight panel.

[0059] A preferred embodiment relates to a plate element according to at least one of the preceding embodiments, wherein the polymeric material of the functional layer of the edge band profile / profile element is a copolymer, preferably a graft copolymer, preferably a maleic anhydride-grafted polypropylene (PP-MAH). This measure has the advantage that the material composition, in particular the proportion of polar groups in the molecular structure, and thus the material properties, can be specifically adjusted.

[0060] Furthermore, it has proven to be extremely advantageous that the polymeric material of the functional layer of the edge banding profile / profile element is selected from the group of polyurethanes (PUR), acrylates, epoxy resins, ethylene vinyl acetates (e.g. EVA dispersions), polyvinyl acetates (PVAC dispersions) and the like, as well as mixtures of two or more of the aforementioned substances.

[0061] A further advantage of the plate element is that the polymeric material of the functional layer of the edge banding profile and / or the profile element incorporates an adhesion promoter system, preferably as aqueous dispersions or solutions in organic solvents of binder resins, which are selected in particular from the group consisting of polyurethanes, polyesters, acrylates, methyl methacrylates, epoxy resins, ethylene vinyl acetates, polyvinyl acetates, polyvinylidenes, natural rubber, as well as mixtures of two or more of the aforementioned binder groups. It can be used with or without the addition of crosslinking / activator components, e.g., based on polyisocyanates, amines, or peroxides. The polymeric material of the functional layer can be applied directly to the back of the base layer during the production of the edge banding profile / profile element.

[0062] It has also proven advantageous for the functional layer of the edgeband profile / profile element to have a thickness of 0.1 µm to 300 µm, preferably 0.2 µm to 75 µm, and particularly preferably 0.5 to 30 µm. This advantageously results not only in economical and cost-effective manufacturing of the edgeband profile / profile element, but also in the functional layer being optimally adaptable to the respective geometry of the edgeband profile / profile element.

[0063] The object of the invention, to provide a method for manufacturing such a plate element with a plate core having at least one narrow surface and a width, and at least one coating arranged on the top and / or the bottom, is characterized by the following steps: • arranging the edge band profile on at least one narrow surface of the plate core, wherein the edge band profile has at least partially a lesser width B2 than the thickness D10 of the plate core of the plate element, • fixing the edge band profile to at least one narrow surface of the panel core, so that the edge band profile is arranged at least partially spaced away from a top and / or a bottom of the panel element, • that at least one separate profile element is arranged on at least one longitudinal edge side L1, L2 of the edge band profile.

[0064] The method for manufacturing such a plate element is further characterized in that the edge band profile is arranged at least partially spaced from a top and / or a bottom of the plate element on at least one longitudinal edge side L1,L2, via at least one recess.

[0065] Furthermore, the method for manufacturing such a plate element is characterized by the fact that the at least one profile element is arranged in at least one recess. It is also advantageous in the method for manufacturing such a plate element that the at least one profile element is fixed in at least one recess.

[0066] Furthermore, the method for manufacturing such a plate element is characterized in that the edge band profile on at least one longitudinal edge side L1,L2 has a width B2 that is 0.2 to 25%, preferably 0.5 to 20%, smaller than the thickness D10 of the plate core of the plate element.

[0067] The plate element will now be described in more detail using these non-restrictive examples.

[0068] They show: Fig. 1: Perspective view of a plate element 1 with an edge band profile 2; Fig. 2: Perspective view of another plate element 1 with an edge band profile 2 and at least one profile element 5; Fig. 3: Perspective view of another plate element 1 with an edge band profile 2 and at least one profile element 5.5', Fig. 4: Perspective view of another plate element 1 with an edge band profile 2 and at least one profile element 5.5'. Fig. 5: Perspective view of another plate element 1 with an edge band profile 2 and at least one profile element 5.5'.

[0069] In the Fig. Figure 1 shows a perspective view of a plate element 1.

[0070] The panel element 1, furniture panel and the like, with a thickness D, comprising at least one edge band profile 2, with at least one base layer 3, wherein the base layer 3 is preferably covered by an outer layer 4, both of which at least partially comprise a polymeric material, both of which have a defined width B3, B4 of 10 to 120 mm, preferably 15 to 100 mm, is characterized in that the edge band profile 2 has at least partially a lesser width B3, B4 than the thickness D of the panel element 1, that the edge band profile 2 is arranged at least partially spaced from a top surface 11 and / or a bottom surface 12 of the panel element 1 on at least one longitudinal edge side L1, L2, and that at least one separate profile element can be arranged on the at least one longitudinal edge side L1, L2 of the edge band profile 2.

[0071] Advantageously, the plate element 1 is designed such that the edge band profile 2 is arranged at least partially spaced from a top surface 11 and / or a bottom surface 12 of the plate element 1 on at least one longitudinal edge side L1,L2, via at least one recess 7, 8.

[0072] It is also advantageous for the plate element 1 to be designed such that the edge band profile 2 has a width B3, B4 that is 0.2 to 25%, preferably 0.5 to 20%, smaller than the thickness D of the plate element 1 on at least one longitudinal edge side L1,L2.

[0073] The plate element is further advantageously designed such that the edge band profile 2 is arranged at least 0.10 to 20 mm, preferably 0.15 to 10 mm, away from the top 11 and / or the bottom 12 of the plate element 1 on at least one longitudinal edge side L1,L2.

[0074] Another advantage of the plate element 1 is that the base layer 3 and / or the outer layer 4 of the edge band profile 2 has at least a functional layer 6 in sections.

[0075] In addition to economical and cost-effective production, it is also possible to optimize the fixation of the edge band profile 2 to a plate element 1 by varying the functional layer 6, for example by designing the functional layer 6 as a so-called adhesion promoter layer and / or by designing the functional layer 6 as a so-called hot melt adhesive layer and / or by designing the functional layer 6 as a polymeric functional layer.

[0076] In this embodiment, the functional layer 6 is arranged on the side of the base layer 3 of the edge band profile 2 opposite the outer layer 4.

[0081] Furthermore, the plate element 1 is designed such that the material of the base layer 3 of the edge band profile 2 has a density of 0.2 g / cm³. 3 up to 0.85 g / cm³ 3 , preferably 0.40 g / cm² 3 up to 0.70 g / cm³ 3 according to DIN EN ISO 1183-1: 2019-09. In this embodiment, the plate element 1 is designed such that the material of the base layer 3 of the edge band profile 2 has a density of 0.45 g / cm³. 3 according to DIN EN ISO 1183-1: 2019-09.

[0082] In this embodiment, the material of the base layer 3 of the edge band profile 2 is polypropylene (PP).

[0083] The plate element 1 is further configured such that the material of the base layer 3 of the edge band profile 2 comprises at least 5 to 80 wt.%, preferably 10 to 75 wt.%, and particularly preferably 15 to 70 wt.%, of recycled material based on the total weight. In this embodiment, the plate element 1 is configured such that the material of the base layer 3 of the edge band profile 2 comprises 50 wt.% of recycled material based on the total weight.

[0084] Advantageously, the plate element 1 is designed such that the material of the base layer 3 and / or the material of the outer layer 4 of the edge band profile 2 contains light- and / or radiation-absorbing additives in an amount of 0.01 to 5 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. In this embodiment, the plate element 1 is designed such that the material of the base layer 3 and / or the material of the outer layer 4 of the edge band profile 2 contains light- and / or radiation-absorbing additives in an amount of 2.5 wt.%, based on the total amount.

[0085] Another advantage of the plate element 1 is that the material of the base layer 3 and / or the material of the outer layer 4 of the edge band profile 2 contains at least one additive, partially containing inorganic and / or organic pigments, in an amount of 0.01 to 5 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount.

[0086] In this embodiment, the plate element 1 is designed such that the material of the base layer 3 and / or the material of the outer layer 4 of the edge band profile 2 contains at least one additive, partially containing inorganic and / or organic pigments, in an amount of 0.5 wt.%, based on the total amount.

[0088] In the Fig. Figure 2 shows a perspective view of a plate element 1 according to a further embodiment of the invention with an edge band profile 2, in which a recess 8 is filled with a profile element 5.

[0089] The panel element 1, furniture panel and the like, with a thickness D, comprises an edge band profile 2 with a base layer 3 made of a polymeric material.

[0090] In this embodiment, a separate outer layer 4 is missing (cf. Fig. 1) and the B-material of the base layer 3 is of such high quality that it meets the optical requirements for a plate element 1, e.g. the B-material can be virgin polymer material, i.e. it can also consist of a material mentioned for the outer layer 4 (= first A-material).

[0091] The base layer 3 has a width B3 = B4 of 10 to 120 mm, preferably 15 to 100 mm. This width B3, B4 is less than the thickness D of the plate element 1, so that the plate element 1 projects beyond the edge band profile 2 on both longitudinal edge sides L1, L2, forming recesses 7, 8 that are angular in cross-section.

[0092] The lower recess 8 is filled with a profile element 5 with an arc-shaped cross-sectional area. Alternatively, the recesses 7, 8 can also be filled using a polymer melt, which solidifies and, if necessary, hardens after application.

[0093] The panel element 1 is further designed such that the edge band profile 2 is fixed to a narrow surface 15 of the panel element 1 via a functional layer 6. In this embodiment, the separate profile element 5 is arranged on the second longitudinal edge side L2 of the edge band profile 2.

[0094] It is also within the scope of the invention that, after the edge banding profile 2 is attached and before the recesses 7, 8 and / or the corner recesses are filled with the various A-materials, the longitudinal edge sides L1, L2 of the edge banding profiles 2 and / or the recesses 7, 8 and / or the corner recesses are processed, for example, by mechanical processing, in particular with a milling cutter, a scraper, and the like. It is further within the scope of the invention that, after the edge banding profile 2 is attached and before the recesses 7, 8 and / or the corner recesses are filled with the various A-materials, the longitudinal edge sides L1, L2 of the edge banding profiles 2 and / or the recesses 7, 8 and / or the corner recesses are processed, in particular with a milling cutter, a scraper, and the like, thereby increasing the volume, in particular of the recesses 7, 8 and / or the corner recesses.

[0095] In this embodiment, after the edge band profile 2 was attached and before the recesses 7,8 were filled with the various A materials, the longitudinal edge sides L1,L2 of the edge band profile 2 and / or the recesses 7,8 were machined, in particular with a milling cutter, a scraper and the like, thereby increasing the volume in particular of the recesses 7,8.

[0096] After the edge banding profile 2 was fixed to the narrow surface 15 of the panel element 1, the separate profile element 5 was bonded to the second longitudinal edge L2 of the edge banding profile 2 and to the narrow surface 15 of the panel element 1. In this embodiment, the separate profile element 5 is designed to be flush with / fixed to the underside 12 of the panel element 1.

[0097] Furthermore, the separate profile element 5 is designed such that it is arranged flush with the front of the base layer 3, projecting away from the narrow surface 15 of the plate element 1.

[0098] Advantageously, the plate element 1 is designed such that the edge band profile 2 is arranged at least partially spaced from a top surface 11 and / or a bottom surface 12 of the plate element 1 via at least one longitudinal edge side L1, L2. In this embodiment, the plate element 1 is designed such that the separate profile element 5 is arranged / fixed in the recess 8 on the second longitudinal edge side L2 of the edge band profile 2.

[0099] It is also advantageous for the plate element 1 to be designed such that the edge band profile 2 has a width B3, B4 that is 0.2 to 25%, preferably 0.5 to 20%, smaller than the thickness D of the plate element 1 on at least one longitudinal edge side L1,L2.

[0100] The plate element 1 is further advantageously designed such that the edge band profile 2 is arranged at least 0.10 to 20 mm, preferably 0.15 to 10 mm, away from the top 11 and / or the bottom 12 of the plate element 1 on at least one longitudinal edge side L1,L2.

[0101] In this embodiment, the plate element 1 is designed such that the edge band profile 2 is arranged at least on one longitudinal edge side L1, L2 spaced 1 mm from the top 11 and / or the bottom 12 of the plate element 1.

[0102] It has also proven advantageous for the plate element 1 that a coating 13 is arranged at least partially on at least one front face of the edge band profile 2 and / or the profile element 5, pointing away from the narrow surface 15 of the plate element 1, as well as on the top surface 11 and / or the bottom surface 12 of the plate element 1. In this embodiment, the plate element 1 is designed such that it has a coating 13 on its top surface 11.

[0103] The coating 13 of the plate element 1 is designed as a film and has a thickness of 100 µm.

[0104] In principle, the exemplary embodiment according to Fig. 2. This is a standard edge banding profile 2 known in the prior art. The difference compared to the prior art is that here the edge banding profile 2 is not wider than the thickness D of the panel element 1, but narrower. This eliminates the milling waste from flush trimming the excessively wide edge banding profile 2.

[0105] Instead, the plate element 1 protrudes beyond the too narrow edge band profile 2, and this protrusion is filled by the second A-material, for example by appropriate application of a polymer melt or a profile element 5 made of second A-material.

[0106] In the Fig. Figures 3 to 5 show the course of a method according to the invention for narrow-area coating of a panel element 1, such as a furniture panel with edge banding profiles 2.

[0107] According to Fig. 3. Initially, only a narrow surface of the plate element 1 has been coated, in Fig. 4 then additionally another narrow surface pointing backwards in the figure, whereby the correspondingly formed corner with the end faces 21', 22 has already been filled and according to Fig. 5. In addition, the coating of the forward-facing narrow surface and the filling of the forward-facing corner (see also end faces marked 21', 22) are carried out.

[0108] The process for coating the narrow surface of the plate element 1 is characterized by the following steps: • The narrow surface coating is carried out using edge band profiles 2, which have a base layer 3 made of B-material, for example recycled material. • The base layer 3, viewed in profile cross-section, is covered on its outer longitudinal side covering the narrow surface with an outer layer 4 of the edge band profile 2 made of a polymeric first A-material. • The edge band profiles 2 have a smaller width B3,4 than the thickness D of the panel element 1, • The edge band profiles 2 are first attached to the narrow surfaces 15 in such a way that the plate element 1 protrudes on both sides, forming recesses 7,8 which are angular in cross-section • then the recesses 7,8 along the edge of the plate element 1 are filled with a polymeric second A-material, for example by means of a melting process.

[0109] The melting process could, for example, involve extrusion.

[0110] It is also within the scope of the invention that after attaching the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are processed, for example by mechanical processing, in particular with a milling cutter, a scraper and the like.

[0111] It is further within the scope of the invention that after the application of the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are machined, in particular with a milling cutter, a scraper and the like, whereby the volume of the recesses 7,8 and / or the corner recesses is increased.

[0112] In particular, it is within the scope of the invention that the second A-material is provided in the form of a filament, which is melted immediately before application. Fig. In layers 3 to 5, the base layer 3 is covered with an outer layer 4.

[0113] In this case, the B-material of base layer 3 is expediently made of a material of reduced quality, e.g. recycled material.

[0114] Since the base layer 3 is covered on the outside by the outer layer 4 in this case, the B material does not affect the appearance of the plate element 1. In particular, the B material in this variant differs from the A material at least with regard to its quality.

[0115] The process is further characterized by the fact that, viewed in the plane of the plate, the edge band profiles 2 are essentially flush with the corner areas of the plate element 1, forming corner recesses perpendicular to the plate plane in the area of ​​the end faces 21, 21', and these corner recesses are filled with a third A-material. This third A-material can differ from the second A-material, for example, in its flow behavior if the third A-material is applied perpendicularly. Here, it may be advantageous, for instance, for the third A-material to have a higher viscosity than the second A-material during application.

[0116] Within the scope of the invention, it is naturally also implied that the third A-material is identical to the second A-material. In principle, the materials mentioned below for the second A-material can also be used for the third A-material.

[0117] Another advantage of the method is that the filling with A-material is carried out by forming a sloping surface or an outwardly curved, filling surface in cross-section, as in the Fig. Shown 3 to 5.

[0118] The process is further characterized by the fact that A-material is used in the form of unrecycled material, in particular new material, which is, for example, polymeric, especially thermoplastic, elastomeric (e.g. silicone-based) or thermosetting and can consist of several components, as well as being in the form of a filler.

[0119] In particular, the second A-material can also consist of a silicone material.

[0120] Furthermore, the second A-material can consist of several components; if necessary, the formation of the second A-material is also possible as a filler, in particular plastic dispersion filler, component filler, as well as as a putty, in particular inorganic putties, organic putties e.g. made of synthetic polymers.

[0121] Advantageously, the second and / or third A-material has a paste-like consistency during processing and then hardens. The second and / or third A-material can be plastically deformable during processing and may cross-link upon hardening, for example, as a radiation-cured material.

[0122] After filling the recesses 7, 8 and / or the vertical corner recesses with the various A materials, these surfaces can be post-processed, for example mechanical post-processing, in particular with a scraper, a milling cutter and the like.

[0123] B-material within the meaning of the invention is, for example, recycled material; however, it is also within the scope of the invention that B-material is, for example, a polymeric, in particular thermoplastic, material, a paper-based material, a veneer-based material or wood-based material, and the like.

[0124] The panel element 1, furniture panel and the like, with a thickness D, comprising at least one edge band profile 2, with at least one base layer 3, wherein the base layer 3 is preferably covered by an outer layer 4, both of which at least partially comprise a polymeric material, both of which have a defined width B3, B4 of 10 to 120 mm, preferably 15 to 100 mm, is characterized in that the edge band profile 2 has at least partially a lesser width B3, B4 than the thickness D of the panel element 1, that the edge band profile 2 is arranged at least partially spaced apart from a top surface 11 and / or a bottom surface 12 of the panel element 1 on at least one longitudinal edge side L1, L2, and that at least one separate profile element 5, 5' is arranged on the at least one longitudinal edge side L1, L2 of the edge band profile 2.

[0128] In this embodiment, the separate profile element 5,5' is designed such that it is arranged / fixed flush with the top surface 11 and the bottom surface 12 of the plate element 1.

[0129] Furthermore, the separate profile element 5,5' is designed so that it is flush with the surface of the front of the outer layer 4, projecting away from the narrow surface 15 of the plate element 1.

[0137] In this embodiment, the separate profile element 5 is produced in an extrusion process known per se and is fixed in recess 8 on the narrow surface 15 of the plate element 1 in a materially bonded manner, for example by adhesive.

[0138] The separate profile element 5 is manufactured in such a way that it has the same cross-section as the recess 8 on the narrow surface 15 of the plate element 1.

[0139] In this embodiment, the separate profile element 5' is inserted directly into the recess 7 on the narrow surface 15 of the plate element 1 via an extrusion nozzle, 3D printing nozzle and the like, and thus fixed in a material-bonded manner.

[0140] After manufacture / installation, the cross-section of the separate profile element 5' was adapted by machining operations so that the separate profile element 5' is flush with the top surface 11 of the plate element 1, which is coated with the coating 13, and also flush with the outer layer 4 pointing away from the narrow surface 15 of the plate element 1.

[0170] The method is further characterized such that the edge band profile 2 is arranged at least partially spaced from a top surface 11 and / or a bottom surface 12 of the plate element 1 via at least one longitudinal edge side L1,L2, over at least one recess 7, 8.

[0171] It is also within the scope of the invention that after attaching the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are processed, for example by mechanical processing, in particular with a milling cutter, a scraper and the like.

[0172] It is further within the scope of the invention that after the application of the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are machined, in particular with a milling cutter, a scraper and the like, whereby the volume of the recesses 7,8 and / or the corner recesses is increased.

[0173] Furthermore, the method is designed such that at least one profile element 5,5' is arranged in at least one recess 7, 8.

[0174] The method is further designed such that at least one profile element 5,5' is fixed in at least one recess 7, 8.

[0175] In the Fig. Figure 5 is a perspective view of another panel element 1, such as a furniture panel with an edge band profile 2,2' and at least one separate profile element 5,5'.

[0176] The method for narrow-surface coating of a panel element 1, in particular a furniture panel, wood-based panel, worktop, chipboard, lightweight panel, interior panel, doors, fiber cement panel or the like, is characterized by the following steps: • wherein the narrow surface coating is carried out using edge band profiles 2 which have a base layer 3 consisting of B-material, for example recycled material, and • wherein preferably the base layer 3, as seen in the profile cross-section, is covered on its outer longitudinal side covering the narrow surface with an outer layer of the edge band profile made of a first, preferably polymeric A-material, • that the edge band profiles 2 have a smaller width B3,4 than the thickness D of the panel element, • that the edge band profiles 2 are first attached to the narrow surfaces 15 in such a way that the plate element 1 protrudes at least on one side, forming recesses 7,8 which are angular in cross-section, and • that afterwards the recesses 7,8 along the edge of the plate element 1 are filled with a second, preferably polymeric A-material, preferably by means of a melting process.

[0177] It is also within the scope of the invention that after attaching the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are processed, for example by mechanical processing, in particular with a milling cutter, a scraper and the like.

[0178] It is further within the scope of the invention that after the application of the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are machined, in particular with a milling cutter, a scraper and the like, whereby the volume of the recesses 7,8 and / or the corner recesses is increased.

[0179] Two embodiments are fundamentally within the scope of the invention.

[0180] According to a first embodiment, the base layer 3 is covered with an outer layer 4. In this case, the B-material of the base layer 3 expediently consists of a material of reduced quality, e.g. recycled material.

[0181] Since the base layer 3 is covered on the outside by the outer layer 4 in this case, the B material does not affect the appearance of the plate element 1.

[0182] In this variant, the B-material differs from the A-material, at least in terms of its quality.

[0183] In a second embodiment of the invention, the B-material is of such high quality that it meets the optical, mechanical and chemical requirements for an edge band profile 2.

[0184] In this case, the B-material is, for example, virgin polymer material.

[0185] In this variant, the B-material can also consist of a material which is subsequently referred to as A-materials.

[0186] Overall, the method according to the invention can therefore be used in particular also when using already known edge band profiles 2 according to the prior art.

[0187] A fundamental advantage of the inventive method is that the milling of protruding edges of the edge band profiles 2 is replaced by a filling process with the second A-material in the corresponding edge areas of the panel element 1. This significantly reduces or even completely eliminates the generation of milling waste.

[0188] According to one embodiment of the invention, the plate element 1 protrudes on both sides and the resulting recesses 7,8 are filled accordingly on both sides of the plate element 1 with the second A-material.

[0189] The process is further characterized in that the edge band profile 2 terminates flush or at least substantially flush with the plate element 1 on one side, so that the filling with the second A-material only takes place on the other side of the plate element 1.

[0190] Furthermore, the process is characterized such that the base layer 3 is also covered on the edge side with the second A-material of the edge band profile 2 on the side that is flush (or substantially flush) with the plate element 1, so that the surface edge of the plate element 1 is also formed only of A-material in this area.

[0191] The process is further characterized by the fact that, viewed in the plane of the plate, the edge band profiles 2 in the corner areas of the plate element 1 are essentially flush with it, forming corner recesses running perpendicular to the plane of the plate, and the corner recesses are filled with a third A-material.

[0192] This third A-material may differ from the second A-material, for example in its flow behavior, if the application of the third A-material is perpendicular.

[0193] Within the scope of the invention, it is naturally also implied that the third A-material is identical to the second A-material. In principle, the materials mentioned below for the second A-material can also be used for the third A-material.

[0194] Another advantage of the method is that the filling with A-material is carried out by forming a sloping surface that fills in cross-section or a sloping, outwardly curved arc.

[0195] The process is further characterized by the fact that A-material is used in the form of unrecycled material, in particular new material, which is, for example, polymeric, especially thermoplastic, elastomeric (e.g. silicone-based) or thermosetting and can consist of several components, as well as being in the form of a filler.

[0196] In particular, the second A-material can also consist of a silicone.

[0197] Furthermore, the second A-material can consist of several components; it may also be formed as a filler, in particular a plastic dispersion filler, a component filler, or as a putty, in particular inorganic or organic putties, e.g., made of synthetic polymers. Advantageously, the second and / or third A-material has a pasty consistency during processing and then hardens, for example, as a radiation-curing material.

[0198] The second and / or third A-material may be plastically deformable during its processing and may cross-link during its curing.

[0199] After filling the recesses 7, 8 and / or the vertical corner recesses with the various A materials, these surfaces can be post-processed, for example mechanical post-processing, in particular with a scraper, a milling cutter and the like.

[0200] B-material within the meaning of the invention is, for example, recycled material; however, it is also within the scope of the invention that B-material is, for example, a polymeric, in particular thermoplastic, material, a paper-based material, a veneer-based material or wood-based material, and the like.

[0201] As explained above, B-material can be identical to A-material in terms of its composition. As also explained above, according to one embodiment, B-material, particularly if a separate outer layer is missing, can also be unrecycled material, especially virgin material.

[0202] The panel element 1, furniture panel and the like, with a thickness D, comprising at least one edge band profile 2, with at least one base layer 3, wherein the base layer 3 is preferably covered by an outer layer 4, both of which at least partially comprise a polymeric material, both of which have a width B3, B4 of 10 to 120 mm, preferably 15 to 100 mm, is characterized in that the edge band profile 2 has at least partially a lesser width B3, B4 than the thickness D of the panel element 1, that the edge band profile 2 is arranged at least partially spaced apart from a top surface 11 and / or a bottom surface 12 of the panel element 1 on at least one longitudinal edge side L1, L2, and that at least one separate profile element 5, 5' is arranged on the at least one longitudinal edge side L1, L2 of the edge band profile 2.

[0203] The plate element 1 is further designed such that the edge band profile 2 is fixed to a narrow surface 15 of the plate element 1 via a functional layer 6.

[0204] In this embodiment, the separate profile element 5 is arranged on the second longitudinal edge side L2 and the separate profile element 5' is arranged on the first longitudinal edge side L1 of the edge band profile 2.

[0205] The separate profile element 5,5' was joined to the respective longitudinal edge side LL1,L2 of the edge band profile 2 and the narrow surface 15 of the plate element 1 in a material-bonded manner after the edge band profile 2 was fixed to the narrow surface 15 of the plate element 1.

[0206] In this embodiment, the separate profile element 5,5' is designed such that it is arranged / fixed flush with the top surface 11 and the bottom surface 12 of the plate element 1.

[0207] Furthermore, the separate profile element 5,5' is designed so that it is flush with the surface of the front of the outer layer 4, projecting away from the narrow surface 15 of the plate element 1.

[0208] The method for producing such a plate element 1 with a plate core 10 having at least one narrow surface 15 and a thickness D, and at least one coating 13 arranged on the top surface 11 and / or the bottom surface 12, is characterized by the following steps: • arranging the edge band profile 2 on at least one narrow surface 15 of the plate core 10, wherein the edge band profile 2 has at least partially a smaller width B2 than the width B10 of the plate core 10 of the plate element 1, • fixing the edge band profile 2 to at least one narrow surface 15 of the plate core 10, such that the edge band profile 2 is arranged at least partially spaced away from a top surface 11 and / or a bottom surface 12 of the plate element 1, • that at least one separate profile element 5,5' is arranged on at least one longitudinal edge side L1, L2 of the edge band profile 2.

[0209] The method for manufacturing such a plate element 1 is further characterized in that the edge band profile 2 is arranged at least partially spaced away from a top surface 11 and / or a bottom surface 12 of the plate element 1 via at least one longitudinal edge side L1,L2, via at least one recess 7,8.

[0210] It is also within the scope of the invention that after attaching the edge band profile 2 and before filling the recesses 7,8 and / or the corner recesses with the various A materials, the longitudinal edge sides L1,L2 of the edge band profiles 2 and / or the recesses 7,8 and / or the corner recesses are processed, for example by mechanical processing, in particular with a milling cutter, a scraper and the like.

[0211] Furthermore, the method for manufacturing such a plate element 1 is characterized by the fact that the at least one profile element 5,5' is arranged in at least one recess 7,8.

[0212] It is also advantageous in the method for manufacturing such a plate element 1 that the at least one profile element 5,5' is fixed in at least one recess 7,8.

[0213] It is also advantageous in the method for manufacturing such a plate element 1 that the edge band profile 2 has a width B2 on at least one longitudinal edge side L1,L2 that is 0.2 to 25%, preferably 0.5 to 20%, smaller than the thickness D10 of the plate core 10 of the plate element 1.

[0214] In this embodiment, the separate profile element 5 is produced in an extrusion process known per se and is fixed in the recess 8 on the narrow surface 15 of the plate element 1 in a materially bonded manner, for example by adhesive.

[0215] The separate profile element 5 is manufactured in such a way that it has the same cross-section as the recess 8 on the narrow surface 15 of the plate element 1.

[0216] In this embodiment, the separate profile element 5' is inserted directly into the recess 7 on the narrow surface 15 of the plate element 1 via an extrusion nozzle, 3D printing nozzle and the like, and thus fixed in a material-bonded manner.

[0217] After manufacture / installation, the cross-section of the separate profile element 5' was adapted by machining operations so that the separate profile element 5' is flush with the top surface 11 of the plate element 1, which is coated with the coating 9, and also flush with the outer layer 4 pointing away from the narrow surface 15 of the plate element 1.

[0218] The coating 9 has a thickness of 1 to 350 µm, preferably 2 to 300 µm, and particularly preferably 5 to 250 µm. In this embodiment, the thickness of the coating 13 is 20 µm.

[0219] The plate element 1 is further designed such that the ratio of the width B10 of the plate core 10 to the width B3 of the base layer 3,3' is at least 1.1; preferably at least 1.2; particularly preferably at least 1.3. QUOTES INCLUDED IN THE DESCRIPTION
