[0003] Method for coating the narrow surface of a panel element

[0004] 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,

[0005] - 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

[0006] - 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.

[0007] 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.

[0008] Edge banding profiles of this type 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.

[0009] 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 generally does not meet the optical, chemical, or mechanical requirements for the surface of the panel's edge banding and can therefore only be used in the non-visible interior of the applied edge banding profiles. REHAU Industries SE & Co. KG, Rehau, August 28, 2025

[0010] Int. sign: 24.006 / 1 dr.lauk

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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. Achieving a secure hold for edge banding profiles / profile elements, especially polymeric edge banding profiles / profile elements, on the narrow surfaces of panel elements is difficult with various materials.

[0015] Furthermore, DE 102010011545 A1 discloses a method for the production of a furniture panel for a piece of furniture and such a furniture panel.

[0016] This furniture panel is designed such that the top 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 look.The process for manufacturing a furniture panel is designed as follows: 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 underside of the plastic panel is coated with a colored lacquer; in a further step, the plastic panel is bonded under pressure to a substrate made of wood or wood substitute; in a further step, after the adhesive has cured, the furniture panel is cut to size; and in a final process step, the cut furniture panel is finished with a plastic edge banding that resembles glass. REHAU Industries SE & Co. KG, Rehau, August 28, 2025.

[0017] Int. sign: 24.006 / 1 dr.lauk

[0018] In current technology, the processing of edgeband profiles sometimes results in more than 20% waste.

[0019] 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.

[0020] 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.

[0021] According to the invention, this problem is solved by the features of claim 1. Further advantageous embodiments are described in the dependent claims.

[0022] 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,

[0023] - 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

[0024] - wherein preferably the base layer, viewed in 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, is characterized in that the edge band profiles have a lesser width than the thickness D of the plate element, and that the edge band profiles, or at least one edge band profile, are first attached to the narrow surfaces, or at least one of the narrow surfaces, in such a way as to REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0025] Int. sign: 24.006 / 1 dr.lauk or is attached, in such a way that the plate element protrudes at least on one side forming recesses, preferably angular in cross-section, or at least one recess, preferably angular in cross-section, and that afterwards or simultaneously the recess or recesses along the edge of the plate element are filled with a second, preferably polymeric, A-material, preferably by means of a melting process, solves this problem.

[0026] In the event that the base layer, viewed in 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, the outer layer of the edge band profile can, for example, be a layer of A-material co-extruded together with the base layer. In further variants, the outer layer can also be a layer of A-material formed by printing and / or by a film and / or by a clear lacquer, sealant, or protective layer.

[0027] As can be seen, for example, in the figures, "the base layer, viewed in cross-section, is covered on its outer longitudinal side covering the narrow surface with an outer layer of the edge band profile" means that the outer layer forms the visible outer surface of the edge band profile when the edge band profile is attached to the narrow surfaces, or to at least one narrow surface. In this case, the base layer is partially or completely covered on the outside by the outer layer.

[0028] The melting process can, for example, be extrusion. It can also include, for example, filament welding, material printing, powder welding, hot melt adhesive application, injection molding (also called extrusion injection molding), or injection molding. Combinations of the aforementioned melting processes are also possible.

[0029] Another advantage of this method is that, viewed in the plane of the panel, at least two edge band profiles, or the edge band profiles themselves, are flush with the panel element in a corner area or in the corner areas, forming a plane perpendicular to the panel. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0030] Int. Ref: 24.006 / 1 dr.lauk The invention relates to the closing or closing of the running corner recess(s) and the filling of the corner recess(s) with a third A-material. 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. 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.

[0031] It is within the scope of the invention that, after attaching the edge band profile and before filling the recess or recesses and / or the corner recess and / or the corner recesses with the A-material or with the A-materials, the longitudinal edge side or the longitudinal edge sides of the edge band profile or the edge band profiles and / or the recess and / or the recesses and / or the corner recess and / or the corner recesses can be processed, for example by mechanical processing, in particular with a milling cutter, a scraper, a saw, an abrasive medium and the like.

[0032] It is further within the scope of the invention that, after the application of the edge band profile and before filling the recess or recesses and / or the corner recess and / or the corner recesses with the A-material or with the A-materials, a, preferably mechanical, processing of the longitudinal edge side or the longitudinal edge sides of the edge band profile or the edge band profiles and / or the recess and / or the recesses and / or the corner recess and / or the corner recesses can be carried out, in particular with a milling cutter, a scraper, a saw, an abrasive medium and the like, whereby the volume in particular of the recess or the recesses and / or the corner recess and / or the corner recesses is increased.

[0033] During the mechanical processing of the recess(s) and / or the corner recess(s), material from the panel element, particularly from the edge of the panel element, can also be removed simultaneously to enlarge the recess(s) and / or the corner recess(s). REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0034] Int. sign: 24.006 / 1 dr.lauk

[0035] When machining the edge of the plate element, at least one hollow structure forming an undercut can be simultaneously introduced into the plate element during material removal. This hollow structure is then filled with the A-material (second A-material and / or third A-material). Advantageously, this also provides additional mechanical anchoring of the filling A-material. The hollow structure can, for example, be T-shaped, Y-shaped, or V-shaped in cross-section.

[0036] The A-material, particularly for the melting process, can contain visible additives that result in a multicolored, marbled, or pigmented appearance. For this purpose, at least two thermoplastic materials with different melt flow indices can be used. In particular, the A-material, especially for the melting process, can be mixed with different color pigments to visually replicate a decorative effect on the edge banding profile, such as a wood grain or marbling.

[0037] Before filling the recess or recesses and / or the corner recess and / or the corner recesses, it may be advantageous to preheat the recess or recesses and / or the corner recess and / or the corner recesses to a temperature between 30°C and 350°C, preferably between 40°C and 250°C, more preferably between 60°C and 130°C, for example by means of hot air, by means of a flame, by means of a corona process or by means of infrared radiation or by means of high-energy radiation (e.g. laser radiation or a plasma beam).

[0038] Two exemplary embodiments are, in principle, within the scope of the invention.

[0039] According to a first 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. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0040] Int. sign: 24.006 / 1 dr.lauk

[0041] 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-material. Overall, the method according to the invention can therefore also be used, in particular, with previously known edge banding profiles.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] A further advantage of the method can be that the base layer, on the side flush (or at least substantially flush) with the panel element, is also covered at its edge with the first A-material of the edge band profile, so that the surface edge of the panel element is also formed solely of A-material in this area. This requires either that the B-material of the base layer corresponds to an A-material or that, viewed in cross-section, the base layer 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.

[0046] Furthermore, within the scope of the invention, it can advantageously be provided that the filling of the recess or recesses and / or the corner recess or recesses is carried out by forming tools (for example, an injection nozzle, or an extrusion nozzle or an extrusion calibration nozzle or an injection mold half). REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0047] Int. Ref: 24.006 / 1 dr.lauk or a forming roller). The forming tools are designed such that the A-material to be filled is placed in a mold, preferably under additional pressure, cooled, or calibrated. In a further embodiment of the invention, it is advantageously provided that the filling of the recess(s) and / or the corner recess(s) with a forming tool is carried out in such a way that the A-material to be filled is melted and melted into the recess(s) and / or the corner recess(s), in particular by means of a melting process.

[0048] It is within the scope of the invention that after filling the recess or recesses and / or the corner recess or recesses with the different or identical A-materials, the surfaces of the A-materials can be post-processed, for example, by mechanical post-processing and / or structuring, in particular with a scraper, a milling cutter, a saw, an abrasive medium, an embossing device (e.g., an embossing roller), laser structuring, and the like.

[0049] 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 can be, for example, a polymeric, in particular thermoplastic, material, a paper-based material (for example, a paper edge, a paper strip, or a paper film), a 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.

[0050] The A-material, in particular the first, second, and / or third A-material, as defined in the invention, is generally not recycled material, as it must meet high optical requirements. The A-material is expediently used in the form of non-recycled material, especially virgin material, which may be, for example, polymeric, particularly thermoplastic, elastomeric (e.g., silicone-based), or thermosetting. In particular, the A-material, especially the second A-material, may also consist of a silicone. Furthermore, the A-material, especially the second A-material, may consist of several components; optionally, the A-material, especially the second A-material, may also be formulated as a filler, particularly a plastic compound. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0051] Int. sign: 24.006 / 1 dr.lauk

[0052] Dispersion filler, component filler, as well as putty, especially inorganic or organic putties, e.g. made from synthetic polymers and the like, are possible.

[0053] A-material, especially for the melting process, may include, for example, an amorphous polyalphaolefin (APAO), a polyurethane (PU), an acrylate (e.g., an ethyl methacrylate (EMA) or an ethylene butyl acrylate (EBA)), an epoxy resin, an ethylene vinyl acetate (EVA), a polyvinyl acetate (PVA), a polyamide (PA), a polyolefin (e.g., a polypropylene (PP) or polyethylene (PE)), a silicone, a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU), a polyvinyl chloride (PVC), a polymethyl methacrylate (PMMA), an acrylonitrile butadiene styrene (ABS), or a polyethylene terephthalate (PET), as well as mixtures of two or more of the aforementioned substances.

[0054] Particularly suitable A-material, especially for the melting process, can be a graft copolymer, preferably a maleic anhydride-grafted polypropylene (PP-MAH) or a maleic anhydride-grafted polyethylene (PE-MAH) or a PP-EMA copolymer or a PP-EBA copolymer or a PE-EBA copolymer or a PE-EMA copolymer.

[0055] Material A, especially for the melting process, may preferably be of the same type or compatible with the material of the base layer and / or outer layer of the edge band profile.

[0056] A-material, especially for the melting process, can contain visible additives that result in a multicolored, marbled, or pigmented appearance. For this purpose, at least two thermoplastic materials with different melt flow indices can be used as A-material.

[0057] Advantageously, the second and / or third A-material can have a pasty consistency during processing and then harden or solidify. The second and / or third A-material can be plastically deformable during processing and solidify upon cooling, or crosslink physically, chemically, or by radiation. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0058] Int. sign: 24.006 / 1 dr.lauk

[0059] A further advantage of the method is that the filling with A-material, in particular with a second A-material and / or a third A-material, can be carried out to form a cross-sectionally filling slope or a filling, outwardly curved arc, or a protective or design edge projecting beyond the upper and / or lower plane of the panel element. In the case of an outwardly curved circular arc, the arc radius can preferably correspond to 1.5 to 50 times, and more preferably to 2 to 25 times, the thickness of the edge banding element.

The filler can further advantageously 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 banding profile, the filler of the at least one base layer can, in particular, comprise barium sulfate, calcium sulfate, calcium carbonate, talc, or wollastonite.

[0093] 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 possibly fully recyclable.

[0094] Another advantage of the panel elements can be that the material price of the edge banding profile / profile element as well as its 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 “CC>2 footprint” than those in the known prior art.

[0095] An advantage of the 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.

[0096] A further advantage of the plate element may be that at least one profile element or the filling made of a second A-material is arranged in at least one recess.

[0097] It can also be advantageous if at least one profile element or the filling made of a second A-material is fixed in at least one recess.

[0098] 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.

[0099] Another advantage of the plate element or the plate element to be manufactured can be that the edge band profile on at least one longitudinal edge side L1, L2 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.

It is further advantageous that the coating can have a thickness of 1 to 350 µm, preferably 2 to 300 µm, and particularly preferably 5 to 250 µm.

[0105] It can also be advantageous for the coating on the front side, facing away from the narrow edge of the panel element, to be 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 achieved, in particular, through multi-color printing, digital printing, gravure printing, or similar processes. In this advantageous configuration, the intensity and feel of the edgeband profile's surface can be further optimized by selecting the appropriate material, thickness, and shape of the coating.

[0106] The coating can advantageously contain renewable raw materials from 0.01 to 100%, preferably 20 to 100%, particularly preferably 40 to 100%.

[0107] All of this leads to economical and cost-effective production of the panel elements with edgeband profiles / profile elements, as well as further optimization possibilities, particularly for the surface and appearance of the edgeband profiles / profile elements.

[0112] 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 can be subjected to surface treatment by a corona treatment, flame treatment, plasma treatment, silicatization treatment, or similar process.

[0187] In this embodiment, a separate outer layer 4 is missing (see 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).

[0188] 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. The lower recess 8 is filled with a profile element 5 with an arcuate cross-sectional area. Alternatively, the recesses 7, 8 can also be filled with a polymer melt made of A-material, which solidifies and, if necessary, hardens after application.

[0189] 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.

[0190] 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 REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0191] Int. Ref: 24.006 / 1 dr.lauk The invention relates to the processing of the longitudinal edge sides L1, L2 of the edge band profiles 2 and / or the recesses 7, 8 and / or the corner recesses with various A-materials, for example, 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 band profile 2 has been applied and before the recesses 7, 8 and / or the corner recesses have been filled 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, 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.

[0192] 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.

[0193] During the mechanical processing of the recess 7, 8 and / or the recesses 7, 8 and / or the corner recess and / or the corner recesses, material from the edge of the plate element 1 can also be removed at the same time in order to enlarge the recess 7, 8 or the recesses 7, 8 and / or the corner recess and / or the corner recesses.

[0194] 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.

[0195] 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.

[0196] Advantageously, the panel 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 panel element 1 via at least one longitudinal edge side L1, L2, via at least one recess 7, 8. In this embodiment, the panel REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0197] Int. sign: 24.006 / 1 dr.lauk 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.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] 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

[0202] 1 designed such that it has a coating 13 on its upper surface 11.

[0203] The coating 13 of the plate element 1 can be designed as a film and can, for example, have a thickness of at least 100 pm.

[0204] In principle, the embodiment shown in Fig. 2 can be a conventional edgeband profile 2 known in the prior art. The difference compared to the prior art is that here the edgeband profile 2 is not wider than the thickness D of the panel element 1, but narrower. This eliminates the milling waste that occurs when flush-trimming the edgeband profile 2, which would otherwise be too wide.

[0205] Instead, the panel element 1 is positioned opposite the edge band profile, which is too narrow.

[0206] 2 and this excess 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.

[0207] Figures 3 to 5 illustrate the process according to the invention for narrow-area coating of a panel element 1, such as a furniture panel with edge banding profiles 2. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0208] Int. sign: 24.006 / 1 dr.lauk

[0209] According to Fig. 3, initially only a narrow surface of the plate element 1 has been coated; in Fig. 4, an additional narrow surface, pointing towards the rear in the figure, has also been coated, with the correspondingly formed corner already filled with the end faces 2T, 22; and according to Fig. 5, the coating of the narrow surface pointing forward and the filling of the corner pointing forward (see also end faces marked 2T, 22) are then carried out additionally.

[0210] The process for coating the narrow surface of the plate element 1 is characterized by the following steps:

[0211] • 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,

[0212] • 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,

[0213] • the edge band profiles 2 have a smaller width B3, B4 than the thickness D of the panel element 1,

[0214] • 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

[0215] • then the recesses 7, 8 along the edge of the plate element 1 are filled with a second polymeric A-material, for example by means of a melting process (for example by appropriate application of a polymer melt).

[0216] The melting process could, for example, involve extrusion.

[0217] It is also within the scope of the invention that, after the edge banding profile 2 has been attached and before the recesses 7, 8 and / or the corner recesses have been 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. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0218] Int. sign: 24.006 / 1 dr.lauk

[0219] 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.

[0220] During the mechanical processing of the recess 7, 8 and / or the recesses 7, 8 and / or the corner recess and / or the corner recesses, material from the edge of the plate element 1 can also be removed at the same time in order to enlarge the recess 7, 8 or the recesses 7, 8 and / or the corner recess and / or the corner recesses.

[0221] In particular, it is within the scope of the invention that the second A-material A is provided in the form of a filament, which is melted immediately before application. According to Figures 3 to 5, the base layer 3 is covered with an outer layer 4.

[0222] In this case, the B-material of base layer 3 is expediently made of a material of reduced quality, e.g. recycled material.

[0223] 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.

[0224] The process is further characterized by the fact that, viewed in the plane of the panel, the edge band profiles 2 are essentially flush with the corner areas of the panel element 1, forming corner recesses perpendicular to the plane of the panel 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 A, 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 during application than the second A-material A. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0225] Int. sign: 24.006 / 1 dr.lauk

[0226] Within the scope of the invention, it is naturally also implied that the third A-material is identical to the second A-material A. In principle, the materials mentioned below for the second A-material A can also be used for the third A-material.

[0227] Another advantage of the method is that the filling with A-material A is carried out by forming a sloping surface in cross-section or a sloping, outwardly curved arc or a protective or design edge projecting beyond the upper and / or lower plane of the panel element, as shown in Figs. 3 to 6.

[0228] The process is further characterized by the fact that A-material can be used in the form of unrecycled material, especially 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.

[0229] In particular, the second A-material can also consist of a silicone material.

[0230] Furthermore, the second A-material A can consist of several components; if necessary, the formation of the second A-material A 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 is also possible.

[0231] Advantageously, the second A-material and / or third A-material can have a paste-like consistency during processing and then harden. The second A-material and / or third A-material can be plastically deformable during processing and solidify upon cooling or cross-link, possibly during hardening, for example, as a radiation-cured material.

[0232] After filling the recesses 7, 8 and / or the vertical corner recesses with the various A-materials, the surfaces of the A-materials can be post-processed, for example, by mechanical post-processing and / or structuring, in particular with a scraper, a milling cutter, a saw, an abrasive medium, an embossing device (e.g. an embossing roller), laser structuring and the like.

[0233] 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 (for example, a REHAU Industries SE & Co.

[0307] Figure 5 shows 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' or a filling made of a second A-material A.

[0308] 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:

[0309] • 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

[0310] • 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 4 of the edge band profile made of a first, preferably polymeric A-material,

[0313] • 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

[0314] • that afterwards the recesses 7, 8 along the edge of the plate element 1 are filled with a second, preferably polymeric, material A, preferably by means of a melting process.

[0315] It is also within the scope of the invention that after the edge band profile 2 has been attached and before the recesses 7, 8 and / or the corner recesses have been filled 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.

[0316] 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.

[0318] Two embodiments are fundamentally within the scope of the invention.

[0319] 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.

[0320] 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 panel element 1. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0321] Int. sign: 24.006 / 1 dr.lauk

[0322] In this variant, the B-material differs from the A-material, at least in terms of its quality.

[0323] 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.

[0324] In this case, the B-material is, for example, virgin polymer material.

[0325] In this variant, the B-material can also consist of a material which is subsequently referred to as A-materials.

[0326] 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.

[0327] 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.

[0328] 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 A.

[0329] 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.

[0330] Furthermore, the process is characterized such that the base layer 3 is also covered on the edge side with the 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.

[0331] The process is further characterized by the fact that, viewed in the plane of the plate, the

[0332] Edge band profiles 2 in the corner areas of the panel element 1 essentially flush REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0333] Int. sign: 24.006 / 1 dr.lauk to complete with this by forming corner recesses running perpendicular to the plate plane and the corner recesses to be filled with a third A-material.

[0334] This third A-material can differ from the second A-material A, for example, in its flow behavior when 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 A. In principle, the materials mentioned below for the second A-material can also be used for the third A-material.

[0335] 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, or a protective or design edge that projects beyond the upper and / or lower plane of the panel element.

[0336] The process is further characterized by the fact that A-material, in particular the second A-material A, can be used in the form of unrecycled material, in particular new material, which is, for example, polymeric, in particular thermoplastic, elastomeric (e.g. silicone-based) or thermosetting and can consist of several components, as well as being in the form of a filler.

[0337] In particular, the A-material, especially the second A-material A, can also consist of a silicone.

[0338] Furthermore, the A-material, in particular the second A-material A, can consist of several components; if necessary, the A-material, in particular the second A-material A, can 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 A-material A and / or third A-material has a pasty consistency during processing and then hardens, for example, as a radiation-curing material.

[0339] The second A-material and / or third A-material may be plastically deformable during its processing and solidify upon cooling or cross-link, possibly upon hardening.

[0340] After filling the recesses 7, 8 and / or the vertical corner recesses with the various A-materials, the surfaces of the A- REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0342] Materials undergo, for example, mechanical post-processing and / or structuring, in particular with a scraper, a milling cutter, a saw, an abrasive medium, an embossing device (e.g. an embossing roller), laser structuring and the like.

[0343] 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 (for example, a paper edge or a paper strip, or a paper foil), a veneer-based material or wood-based material, and the like.

[0344] 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.

[0345] 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 preferably have a width B3, B4 of 5 mm to 150 mm, more preferably of 10 to 120 mm, more preferably of 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' or a filling made of a second A-material is arranged on the at least one longitudinal edge side L1, L2 of the edge band profile 2.

[0360] Furthermore, the method for manufacturing such a plate element 1 is characterized by the fact that the at least one profile element 5, 5' or the filling made of a second A-material A is arranged in at least one recess 7, 8.

[0361] It is also advantageous in the method for producing such a plate element 1 that the at least one profile element 5, 5' or the filling made of a second A-material A is fixed in at least one recess 7,8.

[0362] 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.

[0370] Figures 6a to 6f describe a further embodiment of the inventive method for narrow-area coating of a plate element 1. It is characterized as follows:

[0371] Method for narrow-surface coating of a panel element 1, in particular a furniture panel, wood-based panel, worktop, particleboard, lightweight panel, interior finishing panel, door, fiber cement panel or the like, wherein the narrow-surface coating is carried out by means of edge banding profiles 2 which have a base layer 3 consisting of B-material, for example recycled material, wherein the edge banding profiles 2 have a width B3, B4 less than the thickness D of the panel element 1, wherein at least one edge banding profile 2 is first attached to at least one of the narrow surfaces 15 in such a way that the panel element 1 projects at least on one side, forming at least one recess 7, 8, preferably angular in cross-section, and REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0372] Int. sign: 24.006 / 1 dr.lauk wherein afterwards or simultaneously the recess 7 or the recesses 7, 8 along the edge of the plate element 1 are filled with a second, preferably polymeric, material A, preferably by means of a melting process.

[0373] Figure 6a shows how the edge band profile 2, with a width B3, B4 smaller than the thickness of the plate element 1, is attached to one of the narrow surfaces 15 of the plate element 1. The plate element 1 projects over, forming at least one (here, in cross-section, angular) recess 7, 8. In this case, the plate element 1 projects over on both sides, and the resulting recesses 7, 8 are filled on both sides of the plate element 1 with the second A-material A (this will be described in more detail below).

[0374] After the edge band profile 2 has been attached and before the recess 7, 8 or the recesses 7, 8 and / or the corner recess and / or the corner recesses have been filled with the A-material A or with the various A-materials, the longitudinal edge side L1, L2 or the longitudinal edge sides L1, L2 of the edge band profile 2 or the edge band profiles 2 and / or the recess 7, 8 and / or the recesses 7, 8 and / or the corner recess and / or the corner recesses can be processed, preferably mechanically, in particular with a milling cutter, a saw, an abrasive medium or a scraper, whereby the volume of the recess 7, 8 or the recesses 7, 8 and / or the corner recess and / or the corner recesses is increased. In Figure 6a, the lower longitudinal edge side L2 of the edge band profile 2 and the lower recess 8 have already been mechanically processed accordingly.

[0375] During the mechanical processing of the recess 7, 8 and / or recesses 7, 8 and / or the corner recess and / or the corner recesses, material from the edge of the plate element 1 can also be removed simultaneously to enlarge the recess 7 or the recesses 7, 8 and / or the corner recess and / or the corner recesses. This is shown by comparing the already mechanically processed lower recess 8 with the upper recess 7.

[0376] Figure 6b shows how a mechanical machining operation (here exemplified by a milling cutter) enlarges the recess 7 by increasing the longitudinal edge L1 of the REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0377] Int. sign: 24.006 / 1 dr.lauk

[0378] The edge band profile 2 and the material of the edge of the panel element 1 are removed simultaneously.

[0379] Figure 6c shows how the two recesses 7, 8 are finally formed before or exactly at the time of filling the recesses 7, 8 with the second, preferably polymeric, A-material A, preferably by means of a melting process.

[0380] Figures 6d, 6e, and 6f show that the plate element 1 protrudes on both sides, and the resulting recesses 7, 8 are filled with the second A-material A on both sides of the plate element 1. The filling with A-material A forms a bevel that fills the recess in cross-section (see Fig. 6d), an outwardly curved arch that fills the recess (see Fig. 6e), or a protective or design edge that projects beyond the upper surface of the plate element 1 (see Fig. 6f).

[0381] Figure 6f illustrates a further advantage of the invention, namely that the filling with the second material A can be designed in such a way that it even extends beyond the upper or lower plane of the plate element 1 and forms a protective or design edge. This protective or design edge can, for example, be provided to prevent liquids spilled on the plate element 1 from running over its edge and to keep them on the plate element 1 until they are removed.

[0382] In Figures 6a to 6f, the base layer 3 of the edge band profile 2, viewed in profile cross-section, is covered on its outer longitudinal side, which covers the narrow surface 15, by an outer layer 4 of the edge band profile made of a first, preferably polymeric, A-material. According to this 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. 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 panel element 1. The longitudinal sides of the base layer 3 are subsequently covered by the second A-material of the infill. In particular, the B-material in this embodiment differs from the A-material at least with regard to its quality.In a second embodiment of the invention, the B-material is of such high quality that it meets the optical, mechanical requirements of REHAU Industries SE & Co.

[0383] Int. Mark: 24.006 / 1 dr.lauk and chemical requirements for an edge banding profile 2 are met. In this case, the outer layer 4 can be omitted if necessary. In this case, the B-material is, for example, virgin polymeric material. In this case, the B-material can also consist of a material that is mentioned in the description for A-materials.

[0384] In a variant shown in Fig. 6f, the edge band profile 2 can be flush or at least substantially flush with the plate element 1 on one side, so that the filling with the second A-material A only takes place on the other side of the plate element 1 (here only at the upper recess 7).

[0385] In the event that the base layer 3 of the edge band profile 2, viewed in profile cross-section, is covered on its outer longitudinal side covering the narrow surface 15 with an outer layer 4 of the edge band profile made of a first, preferably polymeric A-material, the base layer 3 can then also be covered on the side flush, or at least substantially flush, with the plate element 1 at the edge with the first A-material of the edge band profile 2, so that the surface edge of the plate element 1 is also formed in this area only by A-material.

[0386] Viewed in the plane of the plate, at least two edge band profiles 2 can terminate essentially flush with the corner area or corner areas of the plate element 1, forming a corner recess or recesses running perpendicular to the plane of the plate, and the corner recess or recesses can be filled with a third A-material, which can be identical to the second A-material A (not shown in detail in Figures 6a to 6f).

[0387] The A-material, in particular the second A-material A, can be used in the form of unrecycled material, in particular new material, which may be polymeric, in particular thermoplastic, elastomeric (e.g. silicone-based) or thermosetting and may consist of several components, as well as being in the form of, for example, filler, putty and the like.
