[0003] Method for coating narrow surfaces of panel elements

[0004] The invention relates to 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.

[0005] - wherein the narrow surface coating is at least partially carried out using edge band profiles which have at least one core made of B-material, for example recycled material, and

[0006] - wherein the core of the strip, viewed in profile cross-section, is covered with polymeric A-material at least on the outside of its longitudinal side covering the narrow surface and on at least one transverse side, preferably to be machined by machining.

[0007] The invention further relates to an edge band profile with at least one core strip having at least one end face and at least one longitudinal edge face, and at least one outer layer / structural layer connected to the core strip having at least one longitudinal edge face, wherein at least one core strip and the outer layer / structural layer comprise at least a portion of a polymeric material, wherein at least one core strip and the outer layer / structural layer have a width B3, B4 of preferably 3 to 120 mm, preferably 5 to 105 mm, wherein at least one core strip and the outer layer / structural layer have a thickness D3, D4 of preferably 0.2 to 12 mm, preferably 0.4 to 10 mm. The invention further relates to the technical field of panel elements, such as furniture panels, wood-based panels, worktops, particleboard, lightweight panels, interior finishing panels, and doors.Fiber cement boards and the like with at least one such edge banding profile. Such edge banding profiles have previously been used primarily for the decoration or protection of narrow surfaces / side edges of objects such as furniture panels, wood-based panels, worktops, chipboard, lightweight panels, interior finishing panels, doors, REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0009] Fiber cement panels and the like. For this purpose, the edge banding profiles are fixed, for example, to the narrow surfaces / side edges of the objects to be decorated or protected.

[0010] It is known from the prior art that the edgeband profiles are first brought into contact with the relevant narrow surfaces of the panel element and thus glued / fixed by means of an activatable adhesive under heat. So-called edgebanding machines are used for this purpose.

[0011] After the ends of the fixed edgeband profiles on the front and rear faces of the panel element are cut off, the edgeband profile is typically shaped in a pre-milling and a chamfering operation. In a further station of the edgebanding machine, the panel elements with the pre-processed edgeband profiles pass through a finishing unit and a device designed as a scraper to give the edgeband profiles their final outer contour while removing the milling marks.

[0012] This is described, for example, in DE9015079 U1.

[0013] Furthermore, such a device for processing the edges of edge band profiles of continuously moving plate-shaped workpieces such as plate elements is disclosed in DE 373281001.

[0014] Furthermore, DE 202015100800 U1 discloses an edge band profile designed as an edge strip. This profile is designed for fastening to a workpiece, in particular for the narrow-surface coating of furniture panels, worktops or similar material panels, and comprises a base layer made of a thermoplastic material with a structured upper surface and a cover layer made of a transparent or translucent thermoplastic material arranged on the base layer. The top surface of the cover layer forms the visible surface of the edge strip completely or partially, and its underside fully or partially abuts the profiled upper surface of the base layer.

[0015] However, the use of materials in edge banding profiles can be further optimized to make them more cost-effective and significantly more sustainable.

[0016] 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, made from waste, returns, recyclates, polymers based on renewable raw materials, or similar materials – so-called B-REHAU Industries SE & Co. KG, Rehau, August 28, 2025

[0017] Int. sign: 24.005 / 1 dr.lauk

[0018] to use material. However, this B-material usually does not meet the requirements (optical, mechanical, chemical, etc.) for the surface of the narrow edges of the panels and can therefore only be used in the interior of the mounted edge banding profiles, which is not visible from the outside.

[0019] A-material meets the high optical requirements for narrow-area coating and consists, for example, of virgin polymer material such as PP, PMMA, ABS, etc.

[0020] However, a problem arises when using edgebands with a core made of B-material encased in A-material in the corner areas of the panel. In a typically rectangular panel, two opposing edgeband profiles usually protrude beyond the other two profiles, which are flush at the panel corners, and are milled at the ends to create rounded corners.

[0021] However, this reveals the core of the molding made of B-material, meaning that, to avoid visual defects in the corner areas, it must ultimately meet comparatively high requirements regarding color, consistency, etc. Therefore, the use of recycled materials, for example, is subject to rather strict limitations in the current state of the art.

[0022] This is where the invention comes in, which is intended to improve the application possibilities of B-material in the narrow-area coating of panel elements.

[0023] The invention further aims to overcome the disadvantages of the prior art and to provide a method for narrow-area coating of, preferably rectangular, panel elements, in particular furniture panels, wood-based panels, worktops, particleboard, lightweight panels, interior finishing panels, doors, fiber cement panels or the like, edge banding profile, which is economical and cost-effective to manufacture, which on the one hand makes it possible to achieve a high-quality visual impression and to retain the previous functions from the prior art, which is also significantly more sustainable, and which comprises at least one panel element with an edge banding profile having at least one core strip having at least one end face and at least one longitudinal edge side, and at least one structural layer / outer layer connected to the core strip having at least one longitudinal edge side.where at least one core layer and the structural / outer layer at least partially comprise a polymeric material, to be specified.

[0025] According to the invention, this problem is solved by the features of claim 1.

[0026] Further advantageous embodiments are described in the dependent claims.

[0027] It has surprisingly been shown that a method for narrow-surface coating of panel elements, in particular furniture panels, wood-based panels, worktops, chipboard, lightweight panels, interior finishing panels, doors, fiber cement panels or the like,

[0028] - wherein the narrow surface coating is at least partially carried out using edge band profiles which have at least one core made of B-material, for example recycled material, and

[0029] - wherein the core of the strip, viewed in profile cross-section, is covered at least on its outer side on its longitudinal side covering the narrow surface and on at least one transverse side, preferably to be machined, with polymeric A-material, which is characterized in that at least one edge band profile attached to the plate element, which covers at least one other edge band profile in the joint area at at least one corner of the plate element, consists at least in the joint area only of A-material, fulfills this task.

[0030] The method according to the invention offers the advantage that, on the one hand, narrow-area coating of panel elements can be produced economically and cost-effectively. On the other hand, the method simultaneously makes it possible to achieve a high-quality visual appearance and to retain the previous functions from the prior art, while the narrow-area coating is nevertheless made significantly more sustainable through the use of B-material in the core of the edge band profile.

[0031] As can be seen, for example, in the figures, "the core of the strip, viewed in cross-section, is covered at least on its outer side along its longitudinal surface covering the narrow area with polymeric A material" means that the visible outer surface of the edge band profile is formed by the polymeric A material when the edge band profile is used on a REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0032] Int. sign: 24.005 / 1 dr.lauk

[0033] The narrow surface is attached. In this case, the core of the strip is covered on the outside by the polymeric A-material.

[0034] It may be provided that the plate element is rectangular and that the two edge band profiles attached opposite each other to the plate element, which in the joint areas at the corners of the plate element cover the other two edge band profiles, consist at least in the joint areas only of A-material.

[0035] An advantage of this method is that even on a post-processed transverse side, the core of the strip remains covered with A-material.

[0036] Another advantage of the method is that in the joint areas, the overlapping edge band profiles can be post-processed to round off the corners of the panel element, so that the corners of the panel element are formed only of A-material.

[0037] It may be provided that in the joint area or joint areas, a post-processing of the covering edge band profile or the covering edge band profiles takes place, rounding off the corner or corners of the panel element, so that the corner or corners of the panel element is or are formed only of A-material.

[0038] B-material within the meaning of the invention is, for example, recycled material, e.g., made from a polymer. Alternatively, B-material can also be a paper-based material (e.g., a paper edge, a paper strip, or a paper foil), a veneer-based material, a wood-based material, and the like. B-material generally differs from A-material in terms of its composition; however, this does not preclude A-material and B-material from being made from the same material but of different qualities. B-material within the meaning of the invention typically does not meet the requirements for the appearance, feel, or material strength of the panel element. B-material may have different material properties compared to A-material, such as lower scratch resistance or lower density.The B-material can, for example, be foamed, in particular open-pore or closed-pore foamed. Within the scope of the invention, the B-material is therefore always covered by the A-material on the outer surface of the plate element. REHAU Industries SE & Co. KG, Rehau, August 28, 2025.

[0039] Int. sign: 24.005 / 1 dr.lauk

[0040] A further advantage of the method can be that the edge band profile is manufactured in such a way that the thickness D3 of the strip core, made of B-material, is a maximum of 99%, preferably a maximum of 90%, particularly preferably a maximum of 80% of the thickness D4 of the edge band profiles or the edge band profile.

[0041] It has also proven advantageous in the process that the edge band profile can be manufactured in such a way that the difference in thickness D4 of the edge band profiles additionally manufactured from A-material to thickness D3 of the strip core manufactured from B-material is at least 0.8 mm, preferably at least 0.5 mm, particularly preferably at least 0.3 mm.

[0042] It has also been found to be advantageous in the method that the edge band profile can be manufactured in such a way that the difference between the width B10 of the core of the panel element and the width B3 of the core of the strip made of B-material is at least 8 mm, preferably at least 4 mm, and particularly preferably at least 1 mm. For example, at least 1 mm.

[0043] Within the scope of the invention, it is fundamentally the case that, in an inventive method for narrow-surface coating of panel elements, an edge band profile containing B-grade material (of the B-material) can, after flush milling with the panel element, as described, for example, in DE 3732810C1, have a minimum distance of at least 0.2 mm, e.g., at least 0.4 mm, in particular at least 1 mm, and in particular at least 2 mm, from the outer surface. This minimum distance takes into account the fact that, due to technical reasons, the edge bands are attached to the narrow surface with a certain variation in height. The described minimum value is advantageous to prevent this from exposing B-material during flush milling.

[0044] One advantage of the method is that the edge band profiles covered in the corner areas can have at least a core made of B-material, while the overlapping edge band profiles have a core made of A-material only or consist entirely of A-material.

[0045] The overlapping edge banding profiles are generally shorter in the longitudinal direction than the overlapping edge banding profiles with a core made of B-material. This is especially true for rectangular panel elements, as the edge banding profiles with a B-material core are then... REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0046] Int. sign: 24.005 / 1 dr.lauk

[0047] The core strips are attached to the longer narrow sides of the panel element, and as a result, more edge banding profile with B-material can be used overall.

[0048] The edge band profile or edge band profiles covered in the corner area may have at least one core made of B-material, while the covering edge band profile or edge band profiles have a core made of A-material only, or consist entirely of A-material.

[0049] It can also be provided that both the edge band profile covering the corner area outside the corner area and the covered edge band profile have at least one core made of B-material, or that both the edge band profiles covering the corner areas outside the corner areas and the covered edge band profiles have at least one core made of B-material.

[0050] A further advantage of the method is that the overlapping edge band profiles can be produced by means of clocked extrusion, in which the core of the strip consists optionally (i.e. alternately) of A-material or B-material according to the clocking, and that the clocked extrusion can be carried out in such a way that the sections forming the corner areas of the plate elements consist only of A-material.

[0051] It may be provided that at least the covering edge band profile or at least the covering edge band profiles are or are produced by means of clocked extrusion, in which the core of the strip consists optionally of A-material or B-material according to the clocking, and that the clocked extrusion is carried out in such a way that the section or sections forming the corner area or corner areas of the panel element consists or consist only of A-material.

[0052] A further advantage of the method can be that the core of the edgeband profiles, which are produced, for example, by clocked extrusion, may have at least one identification element corresponding to the clocking, which marks the beginning / end of the at least one core made of B-material from the core made of A-material. The identification element can be designed, for example, as a coating, embossing, printing, barcode, or RFID element. It is also within the scope of the invention that the A-material and / or the B-material itself can be designed in such a way that it is detectable by sensors. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0053] Int. sign: 24.005 / 1 dr.lauk

[0054] Furthermore, it is also within the scope of the invention that the A-material and / or the B-material may contain additives that are detectable by sensors, or that the A- or B-material as such can be distinguished from a sensor.

[0055] It can also be advantageous in the method that the edge banding profile(s) covered in the corner area have at least one core made of B-material, while the overlapping edge banding profile(s) in which the core is selectively (i.e., alternately) made of A-material or B-material according to the grading pattern each have one end face made solely of A-material. The overlapping edge banding profile(s) preferably always have a greater length in the longitudinal direction than the overlapping edge banding profile(s) with a core made of B-material.This is especially true when dealing with a rectangular panel element, as the edge band profiles with a core made of B-material are then attached to the longer narrow sides of the panel element, and consequently more edge band profile with B-material can be used overall.

[0056] A further advantage of the method is that the edge banding profile(s) covered in the corner area have at least one core made of B-material, preferably always being longer in the longitudinal direction than the covering edge banding profile(s), and that the covering edge banding profile(s) consist entirely of a core made solely of A-material. This is particularly advantageous when dealing with a rectangular panel element, as the edge banding profiles with a core made of B-material can then be attached to the longer narrow sides of the panel element, thus allowing for the use of a greater overall amount of edge banding made of B-material.

[0057] The edgeband profile for carrying out the method according to the preceding descriptions, with a core made of B-material, in particular recycled material, is characterized in that the core, viewed in profile cross-section, can be covered with polymeric A-material at least on its outer longitudinal side covering the narrow surface and on at least one transverse side, preferably to be machined. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0058] Int. sign: 24.005 / 1 dr.lauk

[0059] One advantage of the edge band profile can be that the core of the strip, viewed in the profile direction or longitudinal direction L, has sections made of B-material that alternate with sections made of A-material.

[0060] Another advantage of the edge band profile can be that, in the longitudinal direction L of the profile, at least one first longitudinal edge side of at least one first strip core can be arranged at least partially spaced apart from at least one second longitudinal edge side of at least one second strip core.

[0061] A structural layer / outer layer connected to the core of the strip may be provided.

[0062] The structural layer / outer layer can be U-shaped, enclosing the at least one core strip on three sides, or it can enclose the entire circumference of the at least one core strip. Advantageously, this encloses the B-material, allowing the use of materials / polymers / recyclates that would otherwise be unbondable, particularly not bondable to the panel element. Furthermore, potential migration effects that could lead to a loss of adhesion are eliminated. At least one structural layer / outer layer made of A-material, connected to the core strip, can be provided, having at least one longitudinal edge, wherein at least one core strip and the structural layer / outer layer comprise at least a portion of a polymeric material.

[0063] In the longitudinal direction L of the profile, at least one first longitudinal edge side of at least one first rib core can be arranged at least partially spaced apart from at least one second longitudinal edge side of at least one second rib core.

[0064] A further advantage of the edge band profile can be that, in the longitudinal direction L of the profile, at least one first longitudinal edge side of at least one first strip core is arranged at least partially spaced apart from at least one second longitudinal edge side of at least one second strip core by the structural layer / outer layer consisting of A-material.

[0065] An advantage of the edge banding profile is that, in the longitudinal direction L of the profile, at least one first end face of at least one first core strip is at least partially separated from at least one second end face of at least one second core strip by the structural layer / outer layer. Thus, edge banding profiles are REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0066] Int. sign: 24.005 / 1 available to Dr. Lauk, which can already have a defined length in the longitudinal direction L of their profile during their manufacture, which corresponds to the length of a narrow surface / end face to be coated later, for example of a furniture panel.

[0067] Another advantage of the edgeband profile, which can be manufactured using clocked extrusion, is that the core of the strip has at least one identification element corresponding to the clocking sequence. This element distinguishes the beginning / end of the core made of B-material from the core made of A-material. The identification element can be, for example, a coating, a print, a barcode, or an RFID element.

[0068] A further advantage of the edgeband profile is that, in the longitudinal direction L of the profile, at least one first longitudinal edge of at least one first core strip is at least partially spaced apart from at least one second longitudinal edge of at least one second core strip. This makes it possible to produce cost-effective and economical, sustainable edgeband profiles, as it allows for the production of several edgeband profiles of identical dimensions in the longitudinal direction L in a single manufacturing step.

[0069] Another advantage of the edge band profile can be that, in the longitudinal direction L of the profile, at least one first longitudinal edge side of at least one first strip core is arranged parallel to and spaced apart from at least one second longitudinal edge side of at least one second strip core.

[0070] It can also be advantageous for the edge band profile that, in the longitudinal direction L of the profile, at least one first longitudinal edge side of at least one first strip core is arranged at least partially spaced apart from at least one second longitudinal edge side of at least one second strip core by the structural layer / outer layer.

[0071] The edgeband profiles produced in this way can now be economically and cost-effectively separated from one another in subsequent manufacturing steps and used for narrow-surface coating of, for example, panel elements, furniture panels, wood-based panels, worktops, chipboard, lightweight panels, interior finishing panels, doors, fiber cement panels, and the like. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0072] Int. sign: 24.005 / 1 dr.lauk

[0073] Furthermore, it has proven advantageous for the edge band profile that, in the longitudinal direction L of the profile, at least one core strip can have a width B3 that is 0.2 to 25%, preferably 0.5 to 20%, smaller than the width B4 of the structural layer on at least one longitudinal edge side.

[0074] A further advantage of the edge band profile is that, in the longitudinal direction L of the profile, at least one core strip has a width B3 that is 0.2 mm to 15 mm, preferably 1 mm to 5 mm, smaller than the width B4 of the structural layer / outer layer on at least one longitudinal edge side.

[0075] This makes it possible to provide edge banding profiles where the core material can be made from a different material than the material of the structural / outer layer. Another advantage is the significantly wider range of usable recycled materials in terms of color, quality, etc.

[0076] Impurities, polymers, and the polymer's processing behavior (such as MFI - Melt Flow Index) can be utilized. This leads to economical and cost-effective production of edgeband profiles, which are also sustainable, especially when using recycled material, so that this edgeband profile has a significantly lower "CO2 footprint" than edgeband profiles of the known state of the art.

[0077] Another advantage of the edge band profile can be that the material of at least one strip core is connected to the structural layer / outer layer via at least one functional layer.

[0078] The functional layer acts as an adhesion promoter. Furthermore, the functional layer can be applied by co-extrusion or using a wet chemical process prior to post-co-extrusion.

[0079] Another advantage of the edge band profile can be that the material of the at least one strip core is spaced away from the structural layer / outer layer via at least one functional layer.

[0080] These advantageous measures make it possible to produce different materials for the core and the structural / outer layer cost-effectively and economically using the known coextrusion or post-coextrusion process. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0081] Int. sign: 24.005 / 1 dr.lauk to produce, and to join together in the adjacent contact surfaces in a materially bonded and visually appealing manner.

[0082] A major advantage regarding the sustainability of the edgebanding profile can be that the material of the at least one core strip and / or the structural layer / outer layer contains renewable raw materials (e.g., wood or cellulose fibers) of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%, as demonstrated, for example, by mass balance analysis using ISCC. Advantageously, this ensures that this edgebanding profile has a significantly lower "CO2 footprint" than edgebanding profiles in the known prior art.

[0083] Another advantage of edge banding profiles is that they can promote the recycling of raw materials and, in particular, the reuse of recycled materials.

[0084] It has also proven advantageous that the front of the edge band profile can have a coating, at least in sections.

[0085] A further advantage of the edge band profile can be that the coating on the front side has a thickness of 1 to 350 pm, preferably 2 to 300 pm, particularly preferably 5 to 250 pm.

[0086] It can also be advantageous if the coating on the front side is designed as a co-extruded or post-co-extruded layer, or as a paint application, or as a printing layer, or as a varnish layer.

[0087] This coating, for example, which can be applied as a paint layer or a printed layer, can advantageously be achieved in particular through so-called multicolor 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. The coating can advantageously contain renewable raw materials from 0.01% to 100%, preferably 20% to 100%, and particularly preferably 40% to 100%. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0088] Int. sign: 24.005 / 1 dr.lauk

[0089] All of this leads to an economical and cost-effective production of the profile arrangement as well as further optimization possibilities, especially for the surface or the appearance of the edge band profile.

[0090] A further advantage of the edge banding profile is that the back of the core and / or the structural / outer layer has a functional layer, at least in sections. In addition to the economical and cost-effective production of the edge banding profile, it is also possible to optimize the fixation of the edge banding profile to an object 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.

[0091] A further advantage of the edgebanding profile is that at least one top layer, for example in the form of a lacquer layer, with a thickness of 2 to 60 µm, preferably 5 to 30 µm, is arranged on the front surface. It has also proven advantageous that the top layer on the front surface can comprise at least one acrylic polymer and preferably have a transmittance of up to 80% for visible light across its thickness, measured according to DIN EN ISO 13468-2:2006-07. The top layer can advantageously contain renewable raw materials from 0.01% to 100%, preferably 20% to 100%, and particularly preferably 40% to 100%. In addition to an aesthetically pleasing top surface of the edgebanding profile, mechanical protection can also be implemented, which, however, does not affect the appearance, in particular the optical structural effect of the edgebanding profile.

[0092] In a further advantageous embodiment of the edgeband profile, it has been shown that the back side of the core and / or the structural layer / outer layer of the edgeband profile can be subjected to surface treatment using corona treatment, flame treatment, plasma treatment, silicatization, and similar processes. This allows for an optimized bond of the edgeband profile for a wide variety of material combinations.

[0093] Another advantage of the edge banding profile is that the material of the core of the edge banding profile 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 3in accordance with DIN EN ISO 1183-1: 2019-09. This advantageously allows the weight of the edge banding profile to be reduced accordingly without affecting its stability and strength. Furthermore, it is advantageous that the application REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0094] Int. sign: 24.005 / 1 dr.lauk of the B-material is significantly reduced, so that the edge band profile can be manufactured even more sustainably.

[0095] In a further advantageous embodiment of the edge banding profile, it has been found that the material of the at least one core strip and / or the material of the structural layer / outer layer can contain 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, it can be optimally welded, for example on the narrow sides of furniture pieces, by means of laser welding processes known per se, through the targeted introduction of energy into the material of the at least one core strip and / or the material of the structural layer / outer layer.

[0096] It has also proven advantageous that the material of the at least one core strip and / or the material of the structural layer / outer layer can contain at least one additive, partially containing inorganic and / or organic pigments, in an amount of 0.01 to 10 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. This makes it possible to apply the edge banding profile cost-effectively and economically to the narrow sides of furniture, for example, using almost all currently known radiation-activated methods.

[0097] It is also advantageous for the edge banding profile that the material of the at least one core strip comprises 5 to 50 wt.%, preferably 10 to 45 wt.%, particularly preferably 15 to 35 wt.%, based on its total weight, at least one filler, wherein the filler is selected, in particular, from silicates, carbonates, phosphates, sulfates, sulfides, and the like. Furthermore, the filler may advantageously be selected from the group of layered silicates, as well as carbonates or sulfates of barium and calcium, and the like.

[0098] In a particularly advantageous embodiment of the edge banding profile, the filler material of the at least one core strip can comprise, in particular, barium sulfate, calcium sulfate, calcium carbonate, talc, or wollastonite. The fillers can advantageously consist of renewable raw materials (for example, wood or cellulose fibers) in proportions of 0.01 to 100%, preferably 20 to 100%, and particularly preferably 40 to 100%.

[0100] The material of at least one core strip and / or the structural layer / outer layer can be 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 styrene acrylonitrile (SAN); polybutylene terephthalate (PBT); polyethylene terephthalate (PET); polyoxymethylene (POM); polyamide (PA); polymethyl methacrylate (PMMA); polyphenylene oxide (PPO);

[0102] Furthermore, the edgeband profile can advantageously be designed such that the material of the at least one core strip and / or the structural layer / outer layer 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. The additives can advantageously comprise renewable raw materials from 0.01% to 100%, preferably 20% to 100%, and particularly preferably 40% to 100%.

[0103] Thus, an edge banding profile can be provided that is both economical and cost-effective to manufacture, but also realizes the functions known from the state of the art, such as adhesion strength values, peel strength values, and water resistance.

[0104] Another preferred embodiment relates to an edge banding profile according to one of the previous embodiments, wherein the functional layer is on a preferably halogen-free, 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 elastomer based on olefins (TPO), thermoplastic elastomer based on urethane (TPU), REHAU Industries SE & Co.

[0106] may be based on thermoplastic copolyester (TPC), styrene block copolymers (SBS, SEBS, SEPS, SEEPS and MBS), thermoplastic copolyamide (TPA) and the like.

[0107] The polymeric material can advantageously contain renewable raw materials from 0.01% to 100%, preferably 20% to 100%, and particularly preferably 40% to 100%. This approach has the advantage that the material is readily available at low cost, easy to process, and also simple to chemically modify.

[0108] In a further preferred embodiment, the functional layer can be designed as a thermoplastic functional layer, which makes it possible to apply an edge band profile according to the previously described embodiments without adhesive, i.e. without applying an additional so-called hot melt adhesive immediately before attaching it, and to fix it without a visible joint on a narrow side of a lightweight panel.

[0109] Another preferred embodiment relates to an edge band profile according to at least one of the preceding embodiments, wherein the preferably halogen-free polymeric material of the functional layer can be 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.

[0110] It has also proven advantageous that the halogen-free polymeric material of the functional layer can be 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.

[0111] A further advantage of the edge banding profile is that the preferably halogen-free, polymeric material of the functional layer incorporates an adhesion promoter system, preferably in the form of 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 halogen-free, polymeric material of the functional layer can be applied directly to the back of the core strip during the production of the edge banding profile. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0112] Int. sign: 24.005 / 1 dr.lauk

[0113] It has also proven advantageous that the functional layer of the edgeband profile can have a thickness of 0.1 pm to 100 pm, preferably 0.2 pm to 75 pm, and particularly preferably 0.5 pm to 30 pm. This advantageously leads not only to economical and cost-effective production of the edgeband profile, but also to the functional layer being optimally adaptable to the respective geometry of the edgeband profile.

[0114] It may be provided that the material (the B-material) of the core of the edge band profile 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 preferably in accordance with DIN EN ISO 1183-1 : 2019-09.

[0115] The B-material of the core of the edge band profile can have a foamed or porous structure.

[0116] A further part of the invention is a plate element manufactured using the method described above and / or comprising an edge band profile described above.

[0117] According to the invention, edgeband profiles are available that not only achieve the previously known functional effects, for example against moisture or temperature, but are also significantly more sustainable to manufacture. Furthermore, this enables the recycling of materials, raw materials, and the like, as well as the reuse of recycled materials. It can also be advantageous that a significantly wider range of usable recycled materials can be employed with regard to color, quality (e.g., with regard to impurities or mixtures of different polymers), and the processing behavior of the polymer (e.g., with regard to melt flow).Another advantage of the edge banding profile is that the material price as well as the manufacturing costs are at a very low level, while at the same time the required raw materials are more readily available, so that this edge banding profile has a significantly lower “CO2 footprint” than the edge banding profiles in the known state of the art.

[0118] The edge banding profile is therefore highly versatile and can be applied to various objects such as furniture panels, wood-based panels, worktops, chipboard, lightweight panels, interior finishing panels, doors, fiber cement panels, and the like. In addition to protecting the narrow edge / end face of, for example, a furniture panel, it also allows for improved visual and design aspects. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0122] Furthermore, the plate element can advantageously be designed such that at least two edge band profiles are arranged on narrow surfaces opposite each other.

[0136] Edge band profile.

[0137] Figure 1 shows a perspective view of a panel element 1, such as a furniture panel, with at least one edge band profile 2, 2'.

[0138] The production process involves a narrow-surface coating method for, 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.

[0139] - wherein the narrow surface coating is at least partially carried out by means of edge band profiles 2, 2' which have at least one strip core 3 made of B-material, for example recycled material, and

[0140] - wherein the core of the strip 3, viewed in profile cross-section, is covered at least on its outer side on its longitudinal side covering the narrow surface and on at least one transverse side, preferably to be machined, with polymeric A-material (the A-material forms a structural layer / outer layer 4), which is characterized in that at least one edge band profile 2' attached to the plate element 1, which covers at least one other edge band profile 2 in the joint area at at least one corner of the plate element 1, consists at least in the joint area only of A-material.

[0141] The plate element 1 can be rectangular and the two edge band profiles 2' (the front one is not shown in detail) attached opposite each other to the plate element 1, which cover the other two edge band profiles 2 in the joint areas at the corners of the plate element 1, consist at least in the joint areas only of A-material.

[0142] An advantage of this method is that even on a post-processed transverse side, the core of the strip 3 remains covered by A-material (here the covering profile 2').

[0143] Another advantage of the process can be that in the joint areas, a post-processing of the overlapping REHAU Industries SE & Co. KG Rehau, August 28, 2025, rounds off the corners of the plate element 1.

[0144] Int. sign: 24.005 / 1 dr.lauk

[0145] Edge banding profiles are used so that the panel corners are formed only of A-material.

[0146] Another advantage of the method can be that the edge band profiles 2 covered in the corner areas have a core 3 made of B-material and a structural layer 4 enclosing the core 3 made of A-material, while the covering edge band profiles 2' have a core made of A-material only or are made entirely of A-material.

[0147] A further advantage of the method can be that the edge band profile 2 (see Fig. 2) is manufactured such that the thickness D3 of the strip core 3, 3', made of B-material, is a maximum of 99%, preferably a maximum of 90%, and particularly preferably a maximum of 80% of the thickness D4 of the edge band profiles 2'. In this embodiment, the edge band profile 2 is manufactured such that the thickness D3 of the strip core 3, 3', made of B-material, is a maximum of 99%, a maximum of 80% of the thickness D4 of the edge band profiles 2.

[0148] It has further proven advantageous in the process that the edge banding profile 2 can be manufactured such that the difference in thickness D4 of the edge banding profiles 2 made from A-material to the thickness D3 of the strip core 3, 3' made from B-material is at least 0.8 mm, preferably at least 0.5 mm, and particularly preferably at least 0.3 mm. In this embodiment, the edge banding profile 2 is manufactured such that the difference in thickness D4 of the edge banding profiles 2 made from A-material to the thickness D3 of the strip core 3, 3' made from B-material is at least 0.8 mm.

[0149] It has also been found to be advantageous in the method that the edge band profile 2 can be manufactured such that the difference between the width B10 of the core 10 of the panel element 1 and the width B3 of the core 3, 3' made of B-material is at least 4 mm, preferably at least 8 mm, and particularly preferably at least 10 mm. In this embodiment, the edge band profile 2 can be manufactured such that the difference between the width B10 of the core 10 of the panel element 1 and the width B3 of the core 3 made of B-material is at least 3 mm.

[0150] One advantage of this method is that the edge banding profiles 2 that overlap in the corner areas have at least one core 3 made of B-material, while the overlapping edge banding profiles 2' in the corner areas have a core made only of A-material. In this example, the overlapping edge banding profiles 2' always have a shorter length in the longitudinal profile direction L. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0151] Int. Mark: 24.005 / 1 dr.lauk on, as the covered edge banding profiles 2 with a strip core 3 comprising B-material (see Fig. 1). This is especially true when dealing with a rectangular panel element 1, since the edge banding profiles 2 with a strip core 3 comprising B-material are then attached to the longer narrow sides or narrow surfaces 15 of the panel element 1, and consequently, more edge banding profile 2 with B-material can be used overall.

[0152] A further advantage of the method may be that the covering edge band profiles 2' can be produced by means of pulsed extrusion (see also Fig. 3 or Fig. 4), in which a strip core 3 can also optionally (i.e. alternately) consist of A-material or B-material according to the pulses, and that the pulsed extrusion is carried out in such a way that the sections of the edge band profiles 2' forming the corner areas of the plate element 1 consist only of A-material.

[0153] It can also be advantageous in the method that the edge band profiles 2 covered in the corner areas can have at least one core made of B-material, while the covering edge band profiles 2', in which the core is optionally (i.e. alternately) made of A-material or B-material according to the timing, each have one end face made only of A-material.

[0154] It can also be advantageous in the method that the edge band profiles 2 covered in the corner areas have at least one strip core 3, 3' having a B-material, and are longer in the profile longitudinal direction L than the covering edge band profiles 2', and that the covering edge band profiles 2' consist completely of a strip core 3, 3' having an A-material.

[0155] The plate element 1 is characterized by the fact that the edge band profiles 2, 2' can be attached, in particular fixed, to at least one narrow surface 15, 15' of a plate core 10.

[0156] In this embodiment according to Fig. 1, the plate element 1 is designed such that the edge band profiles 2, 2' are bonded to the narrow surfaces 15, 15' of the plate core 10 without an additional functional layer, in particular an adhesion promoter layer, and are in particular fixed.

[0157] The panel element 1 can be designed such that an edge band profile 2 is fixed to the narrow surface 15 on the left side, the width B4 of which is greater than the width B10 of the panel core 10. REHAU Industries SE & Co. KG Rehau, August 28, 2025

[0158] Int. sign: 24.005 / 1 dr.lauk

[0159] The edge band profile 2 can be further designed such that the width B3 of the strip core 3 is smaller than the width B10 of the panel core 10.

[0160] The longitudinal edge L42 of the structural layer 4 made of A-material thus extends beyond the top surface 11 of the plate element 1. The longitudinal edge L41 of the structural layer 4 extends beyond the bottom surface 12 of the plate element 1.

[0161] In a subsequent operation, the longitudinal edge sides L41, L42 of the structural layer 4 must now be machined so that the width B4 of the structural layer 4 corresponds to the width B10 of the core of the plate 10.

[0162] Another edge band profile 2 is arranged on the right narrow surface 15' of the panel element 1. The edge band profile 2 is fixed to the narrow surface 15' of the panel element 1.

[0163] The width B4 of the structural layer 4 of the edge band profile 2 is the same as the width B10 of the plate element 10.

[0164] The width B3 of the core strip 3 of the edge band profile 2 is smaller than the width B10 of the panel element 10, and also smaller than the width B4 of the structural layer 4 made of A-material.

[0165] The longitudinal edge L41 of the structural layer 4 is flush with a coating 9 arranged on the top 11 of the panel element 1. The longitudinal edge L42 of the structural layer 4 of the edge band profile 2 is flush with the bottom 12 of the panel element 1.

[0166] 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 strip core 3 is at least 1.1; preferably at least 1.2; particularly preferably at least 1.3.

[0167] The panel element 1 is shown here such that no edge banding profile 2' is arranged on the front, visible narrow side 15 of the panel core 10, so that the structure or construction of the edge banding profile 2 arranged on the left narrow side 15, as well as the edge banding profile 2 arranged on the right narrow side 15', is recognizable.

[0169] The panel element 1 is further designed such that at least two edge band profiles 2 are arranged on opposite narrow surfaces 15, 15', wherein the two edge band profiles 2 each have a core 3 made of B-material. In this embodiment, the panel element 1 is designed such that the two edge band profiles 2 are arranged on opposite narrow surfaces 15, 15' such that the core 3 is visible on the respective end face 21, 22.

[0170] Furthermore, in this embodiment, the plate element 1 is designed such that an edge band profile 2' is arranged, in particular fixed, on the rear, non-visible narrow surface of the plate core.

[0171] The edge band profile 2' is designed such that it has at least one core strip made of A-material, which has at least one end face 31 , 32 and at least one longitudinal edge face L31, L32.

[0172] In this embodiment, the edge band profile 2' is formed on the plate element 1 such that the longitudinal edge sides L31, L32 are arranged flush with the top 11 and the bottom 12 of the plate element 1.

[0173] Furthermore, the edge band profile 2' is arranged on the plate element 1 in such a way that its free ends completely cover the end faces 22 of the edge band profiles 2.

[0174] The edge band profiles 2, which are covered in the corner areas and have a core 3 made of B-material, are covered by the edge band profiles 2' (only the rear one is shown here), in which the core is optionally (i.e., alternately) made of A-material or B-material according to the gradation, but in the corner areas each have one end face made of A-material only.

[0175] Figures 2, 3 and 4 below illustrate possible designs of edge band profiles for carrying out the method described above.

[0176] Figure 2 shows a perspective view of an edge band profile 2, 2'.
