Description

[0001] The invention relates to a facade cladding profile comprising a base profile comprising hollow chambers made of a first plastic, preferably a first extruded plastic, wherein the base profile has a surface which is provided with a surface coating to form a visible surface, and wherein on one side of the base profile a plug-in area is formed which is located laterally next to its surface and is lower in level than the surface, in particular which can be inserted into a receiving area of ​​an adjacent facade cladding profile, and wherein on the other side of the base profile a receiving area is formed, preferably a receiving area located below its surface, in particular into which a plug-in area of ​​an adjacent facade cladding profile can be inserted at least partially, and wherein a shadow gap surface made of a second plastic is formed on a partial area of ​​the plug-in area,which is firmly bonded, preferably by coextrusion, to the first plastic of the base profile.

[0002] An element produced by coextrusion, such as a shadow gap surface, is understood to be an element that was created by the coextrusion process at the same time as the base body, which was also produced by extrusion.

[0003] The aforementioned other side is the opposite side, so that on the facade cladding profile the plug-in area and the receiving area are arranged parallel to each other and each running in the extrusion direction of the profile.

[0004] In this case, a shadow gap surface is preferably understood to mean a surface which forms the joint base in a shadow gap, which is lower in level than the visible surface, in particular which lies with a height difference below the visible surface, preferably which is formed parallel to the visible surface.

[0005] The shadow gap surface of the plug-in area forms the base of a shadow gap that is created between two adjacent

[0006] Facade cladding profiles are formed when they have been connected to one another with a plug-in area and a receiving area. The plug-in area is preferably received in a groove of the receiving area of ​​another facade cladding profile using an element referred to as a spring element. Other areas of the plug-in area arranged next to the spring element are preferably located at least below the receiving area of ​​the other facade cladding profile after connection.

[0007] Such a facade cladding profile or panel made of plastic is preferably one-piece with regard to the base profile and can be produced by means of extruded casting or

[0008] Extrusion produces profiles. Thermoplastics, especially PVC (polyvinyl chloride), are the preferred plastic material for the base profile. PVC is also used, for example, in window frame construction and for pipes.

[0009] During production, the PVC material, preferably in granulate form, is thermally melted and pressed through a mold. The PVC cools slowly and retains its shape. The shapes can have a wide variety of contours. Typically, a basic profile has hollow chambers that are bordered by webs, with

[0010] The cross-section remains constant in the longitudinal direction / extrusion direction.

[0011] Facade cladding profiles are well-known in the art. They are used, for example, to clad the facades of buildings or mobile homes.

[0012] To fix the facade cladding profiles on the wall of a building, a substructure, e.g. made of wood, is provided on the wall of the building, on which the facade cladding profiles, in particular those which can be several meters long, are attached.

[0013] The plug-in area can preferably have a plurality of openings arranged one behind the other in the longitudinal direction, in particular in a fastening area, which serve to receive fastening means, e.g. nails or screws, by means of which the individual plastic facade cladding profiles can be fastened to the substructure on the wall, for example of a building.

[0014] However, the plug-in area is not only used to connect the facade cladding profiles to the substructure on the wall of a building, but two such facade cladding profiles can be connected to each other in the manner of a tongue and groove connection using the plug-in area and a corresponding receiving area.

[0015] For this purpose, the plug-in area, which can be functionally designed as a fastening strip, in particular comprising a spring element, extends on one side of the facade cladding profile over the length of the facade cladding profile. Correspondingly, a corresponding receiving area, in particular with a receiving groove for receiving the preferably provided spring element, runs on the opposite long side of the facade cladding profile.

[0016] The visible surface of facade cladding profiles can be designed in many different ways. For example, it is known to form the visible surfaces using foil, particularly where the foil is designed in a desired color and / or has a texture, in particular mimicking the appearance of a wooden surface.

[0017] According to the state of the art, solid foam profiles with adhesive decorative foils are widely used. The foil surfaces extend continuously across the entire surface, i.e., across the raised visible areas and the recessed shadow gap areas.

[0018] A facade cladding profile of the type mentioned above is known, for example, from the publication DE20 2021 106 311 U1 by the same applicant.

[0019] The disadvantage of this construction is that in this state of the art the film used as a surface coating extends beyond the visible surface, in particular over wall areas sloping downwards from the visible surface, down to the level of the shadow gap area, whereby by joining two facade cladding profiles only a single shadow gap is formed, which only differs from the optical appearance of the visible surface in the shadow gap area at the base of the shadow gap, but not in the wall areas of the shadow gap, since these are also covered with the film.

[0020] It is therefore an object of the invention against the background of this prior art to create a construction of a facade cladding profile in which the shadow gap walls also contribute to the optical differentiation compared to the visible surface in order to create a visually more dominant appearance of the shadow gap.

[0021] Since customers often desire a high number of shadow gaps in the appearance, this requires the installation of a correspondingly high number of facade cladding profiles in the aforementioned prior art. Therefore, a further object of the invention is to increase the number of shadow gaps while maintaining the number of facade cladding profiles to be installed.

[0022] This object is achieved in that, in a facade cladding profile of the type mentioned at the outset, the base profile has on one side a wall region sloping from its surface to the plug-in region, on which wall region a shadow gap wall is formed from the second plastic, which is materially bonded, preferably by coextrusion, to the first plastic of the base profile, wherein this shadow gap wall is formed integrally with the shadow gap surface of the plug-in region, and further in that the base profile has on the other side a wall region sloping from its surface to the receiving region, on which wall region a shadow gap wall is formed from the second plastic, which is materially bonded, preferably by coextrusion, to the first plastic of the base profile. It is provided that each shadow gap wall extends at least to the height level of the surface of the base profile.

[0023] This design according to the invention results in the shadow gaps formed by connecting adjacent facade cladding profiles being formed from the same second plastic both in their shadow gap surface and in their shadow gap walls.

[0024] In this way, it can be achieved that a particular shadow gap can be designed completely differently in its optical appearance, i.e. in the shadow gap surface and shadow gap wall, than the surface coating arranged on the surface of the base profile to form the visible surface.

[0025] When viewed perpendicular to the visible surface, which is created by the coated surface of the base profile, the shadow gap already appears wider than in the aforementioned prior art. Furthermore, the light incidence angle on the shadow gap walls is different from that on the shadow gap surface and the visible surface, which further influences the visual appearance.

[0026] Such a different optical appearance can be achieved, for example, by a different color of the second plastic and / or a different structuring of the second plastic compared to the surface coating on the surface of the base profile.

[0027] To achieve the preferably stated object, the invention further provides, in an equally preferred embodiment, that in the surface of the base profile between the plug-in area and the receiving area, in particular running parallel to these, at least one groove is formed, on the groove base of which a shadow gap surface made of the second plastic is formed and on the opposite groove walls of which shadow gap walls are formed from the second plastic, which is connected in a materially bonded manner, preferably by coextrusion, to the first plastic of the base profile.

[0028] Such a groove, of which at least one, preferably three, is provided in this preferred embodiment, divides the surface of the base profile into adjacent surface sub-regions, each provided with a surface coating, preferably with the same coating, so that in the facade cladding profile according to the invention, its visible surface is divided into at least two adjacent visible surface sub-regions by the at least one shadow gap created in the groove. Preferably, all surface sub-regions lie in a common (the same) plane and / or all visible surface sub-regions lie in a common plane.

[0029] It can preferably be provided that all surface sub-areas and thus also all coated visible surface sub-areas of a facade cladding profile have the same width, in particular viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0030] Alternatively, it can also be provided that at least two surface sub-regions and thus also at least two coated visible surface sub-regions of a facade cladding profile have different widths, in particular viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0031] Likewise, it can preferably be provided that all shadow gaps formed on a facade cladding profile, in particular also between two facade cladding profiles, have the same width, in particular viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0032] Alternatively, it can be provided that at least two shadow gaps of all shadow gaps formed on / in a facade cladding profile and / or between two facade cladding profiles have different widths, in particular viewed perpendicular to the longitudinal direction and / or extrusion direction.

[0033] Furthermore, all shadow gap surfaces of a facade joint profile according to the invention preferably lie, at least with their respective central longitudinal axes, in particular completely, in a common (the same) plane that is parallel to the aforementioned plane of the visible surface / surface partial areas. It can also be provided that a respective shadow gap surface is inclined by an angle from a position parallel to the surface / visible surface.

[0034] Preferably, in this embodiment with at least one additional shadow gap, all shadow gap walls extend from

[0035] The shadow gaps created by the façade cladding profile or by joining two façade cladding profiles extend to the height level of the surface of the base profile, particularly starting from a shadow gap area. Both the shadow gaps created by joining and the shadow gaps present in the façade cladding profile thus exhibit a uniform appearance. The observer thus sees a façade image that appears to be composed of a much larger number of façade cladding profiles than is actually the case.

[0036] In a first possible embodiment, the invention preferably provides that the surface coating of the surface, in particular of each surface portion, is formed by a film. Such a film can, for example, be firmly bonded to the surface of the base profile, e.g., by means of an adhesive.

[0037] In particular, it is intended that the visible side of the plastic film is designed in a different color than the visible areas of the shadow gap.

[0038] In this film embodiment, it is particularly preferred that the film rests on the upper end region of a respective shadow gap wall, preferably is integrally connected thereto, in particular rests on an upper end region of the respective shadow gap wall, which extends parallel to the surface of the base profile, in particular extends beyond the thickness of the shadow gap wall.

[0039] A respective shadow gap wall made of the second plastic thus preferably has, viewed in cross-section perpendicular to the longitudinal direction of the facade cladding profile, a leg that extends parallel to the groove wall in the base profile and has an (upper) leg bending from this direction at the upper end, which lies parallel to the surface of the base profile and / or the film plane. This upper leg simultaneously forms a collar or flange area on both sides of the shadow gap opening.

[0040] The groove wall in the base profile is also understood here to mean the aforementioned sloping wall areas of the base profile, although these do not define a groove originally present in the facade cladding profile, but only a groove created by plugging together.

[0041] The thickness of the shadow gap wall is preferably considered in an area where the first leg is parallel to the groove wall.

[0042] Preferably, the upper leg extends parallel to the surface of the base profile and / or the film plane by at least 50% of the thickness of the shadow gap wall, more preferably by at least 75% of the thickness, even more preferably by at least 100% of the thickness beyond this, but in particular by no more than 200% beyond this.

[0043] In particular, the shadow gap wall on the side of the facade cladding profile with the receiving area can also be provided with a (lower) leg at its lower end, which is bent toward the receiving groove of the receiving area. The shadow gap wall formed on the receiving area thus encompasses a profile area of ​​the base profile with its upper and lower legs. This lower leg can preferably not run parallel to the surface of the base profile or the film plane.

[0044] Such a lower leg can preferably also be provided in the embodiments mentioned below, in particular in all possible embodiments of the invention.

[0045] In another second preferred embodiment, it is provided that the surface coating is formed from the second plastic or from a third plastic which is integrally bonded, preferably by coextrusion, to the first plastic of the base profile.

[0046] In this embodiment, in the first alternative, the shadow gap surface, the shadow gap walls, and the surface coating are formed entirely in one piece from the second plastic, which is bonded to the first plastic of the base profile in a material-to-material manner, preferably by coextrusion. Preferably, the base profile is thus completely coated with the second plastic on the visible side, i.e., in the surface coating and the shadow gaps, in a material-to-material manner, in particular by coextrusion, preferably except in a region of the plug-in area that lies laterally outside the shadow gap surface of the plug-in area.

[0047] A visual demarcation between the shadow gap and the visible surface is thus created at least by the shaded position of the shadow gap below the surface level of the visible surface.

[0048] By using a third plastic for the surface coating instead of the second plastic from which the shadow gaps are formed, a visually different appearance of the surface coating compared to the shadow gap can be created, even if both are produced by co-extrusion.

[0049] The third plastic can preferably differ from the second plastic, for example, only in that it has a different color pigmentation than the second plastic, but in particular the plastic matrix material into which the color pigments are mixed is otherwise the same. However, the third plastic can also be chemically different from the second plastic, thus differing not only in the color pigmentation but also in the plastic matrix material.

[0050] When using a third plastic in the surface coating, it is further preferably provided that this third plastic is also materially bonded, in particular by coextrusion, to the second plastic by which the shadow gap wall is formed in the transition area from the surface coating to a respective shadow gap wall.

[0051] A second and a third plastic are preferably extruded through separate coextrusion dies.

[0052] Even if the surface coating, as in the case of the shadow gap surfaces and shadow gap walls, is formed from the second plastic, it is preferably provided that the surface coating is produced with a different coextrusion nozzle than the shadow gap wall and shadow gap surface of a shadow gap, wherein the latter two can preferably be produced from the same coextrusion nozzle.

[0053] It can be provided that a separate coextrusion nozzle is used for each shadow gap, or partial shadow gaps in the case of shadow gaps that only arise through joining, and for each surface coating, especially for each partial surface area. This also makes it possible to operate different coextrusion nozzles with different plastics.

[0054] It is further preferably provided that the second plastic or the third plastic has a different structure in the area of ​​the surface coating than in the area of ​​the shadow gap walls and / or shadow gap surfaces.

[0055] Visual differentiation can also be achieved through various types of structuring. Preferably, the second plastic or the third plastic is structured in the area of ​​the surface coating, e.g., brushed, embossed, or printed, and the second plastic is extruded without further processing, particularly unstructured, in the area of ​​the shadow gap walls and / or shadow gap surfaces.

[0056] Brushing and / or embossing and / or printing in the area of ​​the visible surface or the surface coating can result in high and low areas that have a different optical appearance, e.g. because in the low areas there is a thinning of the material of the second or third plastic over the first plastic of the base profile, in particular if necessary so that the first plastic shines through the second or third plastic.

[0057] In general, it can be provided that the second plastic is designed in a different color than the surface coating, in particular if this is designed as a film, and / or than the first plastic and / or than the third plastic.

[0058] In all embodiments, it is preferably provided that the first and second plastics and / or the first and third plastics are arranged adjacent to one another in a stepless and / or edgeless manner.

[0059] Preferably, it is generally provided that the layer of the second plastic on the shadow gap surfaces and / or shadow gap walls, in particular also the layer of the second or third plastic in the area of ​​the surface coating, has at least a thickness (d) which, with a predetermined color pigment admixture in the second or third plastic, in particular a light color pigment admixture, ensures complete color coverage of the material / the first plastic of the base profile, in particular the wall thickness (d) is greater than 400 micrometers.

[0060] In all possible designs, it is preferably provided that each shadow gap has a shadow gap surface with a width b that is less than or equal to the width a of the shadow gap opening, in particular the shadow gap opening at the height of the surface of the base body or at the height of the surface coating. This achieves a construction in which the shadow gap widens outward, which facilitates the incidence of light onto the shadow gap walls, preferably those that are not perpendicular to the shadow gap surface in this design.

[0061] The width mentioned is preferably considered here in the direction of the spacing of the plug-in area and the receiving area, in particular perpendicular to the longitudinal direction or extrusion direction of the facade cladding profile.

[0062] It is further preferably also provided that the opposing shadow gap walls of a respective shadow gap present in the facade cladding profile or of a shadow gap formed by connecting two facade cladding profiles are not arranged mirror-symmetrically around a plane lying perpendicular to the shadow gap surface and parallel to the longitudinal direction of the facade cladding profile.

[0063] Particularly preferably, the two shadow gap walls opposite each other in a shadow gap are arranged at different angles to the surface coating. For this purpose, the angles formed by the respective shadow gap wall extending beyond the surface coating and the surface coating can be considered. This angle is preferably larger for the shadow gap wall facing the plug-in area, in particular the one located at the top after the installation of facade cladding profiles, than for the shadow gap wall facing the receiving area, in particular the one located at the bottom after the installation of facade cladding profiles.

[0064] In all possible embodiments, it is further preferably provided that the second plastic in the region of a shadow gap, where it transitions from the shadow gap surface into the shadow gap wall, is formed in the contact area with the first plastic with a smaller radius of curvature (outer radius) between the shadow gap surface and the shadow gap wall than the radius of curvature (inner radius) in the free interior of the shadow gap. As a result of this or another, in particular non-radial, configuration, an accumulation of the second plastic material can preferably be formed in the free interior at the aforementioned transition area.

[0065] In all possible embodiments, the second plastic or the third plastic is preferably formed from a flowable plastic raw material provided with color pigments. In a preferred and limiting example, the color pigments constitute 2% to 2.5% of the mass of the plastic raw material.

[0066] Instead of the first and second or third plastics being different colors, it is also possible for the two plastic materials of the first and second or third plastics to be different except for the color pigment. Thus, chemically different plastics can also be used.

[0067] The shadow gap surfaces and / or shadow gap walls and / or surface coating, which are preferably produced by coextrusion, are preferably extruded onto the base profile and are thus firmly bonded to it, preferably also to each other.

[0068] Advantageously, the base profile, in particular made of recycled rigid PVC, in particular conventionally in grey colour, has a wall thickness which is higher, preferably several times higher, than the wall thickness of the areas produced by coextrusion.

[0069] Since expensive color pigments are preferably added to the coextruded second or third plastic during coextrusion, the wall thickness of the second or third plastic is preferably not made thicker than necessary for cost reasons.

[0070] For an attractive appearance during assembly of the facade, complete opacity of the second and / or third plastic material over the first plastic material of the base profile is preferred. Particularly in the case of light shadow gap surfaces, the base profile, on or to which the second and / or third plastic material is extruded, must not show through the second and / or third plastic material.

[0071] In practice, a thickness of at least 400 µm = 0.4 mm has proven to be suitable for full coverage of the second and / or third plastic.

[0072] The second and / or third plastic preferably has a constant wall thickness in cross-section.

[0073] The invention is explained in more detail below with reference to the drawings.

[0074] The figures show in detail: Fig. 1: the state of the art Fig. 2: a facade cladding profile of a first embodiment according to the invention with foiled surface and co-extruded shadow gaps shown in cross section Fig. 2A-C: detailed representations of the first embodiment of Figure 2 Fig. 3: a second embodiment of a facade cladding profile according to the invention with co-extruded shadow gap and co-extruded surface coating shown in cross section.

Fig. 5preferred embodiments of the shadow gap.

[0075] The Figure 1first shows the prior art originating from the applicant himself with some essential features which the invention also has.

[0076] Shown here is a cross-section of a facade profile 1 with hollow chambers, taken along the longitudinal direction, which also corresponds to the extrusion direction. It comprises a base profile 2, extruded from PVC, for example, which has a surface 2a on its upper side, which corresponds to the visible side when properly installed, which is provided with a film as a surface coating 3, in order to determine the optical appearance with the film.

[0077] On the side shown here on the right, the base profile has a plug-in area 4 with which the facade cladding profile 1 can be plugged into a receiving area of ​​another facade cladding profile, which can be seen on the left of this facade cladding profile 1 shown here as receiving area 5.

[0078] The plug-in area 4 is lower in height than the surface 2a of the base profile or the surface coating 3. Here it comprises a shadow gap surface 5 which, laterally next to the surface 2a, adjoins a vertically sloping wall area 2b of the base profile. The shadow gap surface is at a lower level, in particular parallel to the surface 2a, and is formed from a second plastic which, for example by coextrusion, is materially bonded to the first plastic from which the base profile 2 is formed. This second plastic has a different optical appearance than the first plastic and / or the film surface coating 3, for example because the second plastic of the shadow gap surface is colored differently, for example with pigments mixed into the plastic.

[0079] Adjoining this to the outside, in particular further reduced in height, the plug-in area 4 has a fastening area 4a, which may, for example, have holes / bores or other recesses to enable the facade cladding profile 1 to be fastened to a substructure (not shown). Adjoining this even further to the outside, the plug-in area 4 has a spring element 4b, which is intended to be inserted into the groove 5a of the receiving area 5 (of another adjacent facade cladding profile not shown here).

[0080] The receiving area 5 is located in the facade cladding profile 1 below the surface of the base profile 2 and is therefore not visible from the visible side. On the left side, the facade cladding profile 1 has a wall area 2c that slopes downwards from the surface 2a of the base profile 2b toward the receiving area 5. In the receiving area 5, there is a receiving groove 5a for receiving a groove element 4b of an adjacent facade cladding profile.

[0081] The film, which forms the surface coating 3 here, is attached to surface 2a and also to the wall areas 2b and 2c sloping downwards from surface 2a. In the prior art, a shadow gap formed between two facade cladding profiles is thus distinguished from the film in color only by the shadow gap surface 5. Such a shadow gap is therefore hardly noticeable.

[0082] All of the above-mentioned features, with the exception of the film used as a surface coating and its specific course, are also provided for in the invention.

[0083] In the invention, a film can also be used as a surface coating in a first possible embodiment, but in the invention this only covers the surface 2a, but not the sloping wall areas 2b and 2c.

[0084] Such an embodiment according to the invention is described in Figure 2 and in detail in the Figures 2A to 2C shown.

[0085] As essential to the invention and in contrast to the prior art, the base profile 2 has on the right-hand side a wall region 2b sloping from its surface 2a to the plug-in area 4, on which wall region a shadow gap wall 7 is formed from the second plastic, which is integrally bonded, preferably by coextrusion, to the first plastic of the base profile 2. This shadow gap wall 7 is formed integrally with the shadow gap surface 6 of the plug-in area 4. Furthermore, the base profile 2 has on the other left-hand side a wall region 2c sloping from its surface 2a to the receiving area 5, on which wall region a shadow gap wall 7 is formed from the second plastic, which is integrally bonded, preferably by coextrusion, to the first plastic of the base profile 2. Each shadow gap wall 7 extends at least to the height level of the surface 2a of the base profile 2.

[0086] By joining two facade cladding profiles 1 of this type according to the invention, a visually more striking shadow gap is created compared to the prior art, because in the invention, the shadow gap walls 7 are also formed from the same second plastic. This already results in a visually larger width of the shadow gap formed in this way.

[0087] The Figure 2illustrates a particularly preferred embodiment in which at least one further groove 8, here three further grooves 8, are provided in the surface 2a of the base profile, at the groove base of which a shadow gap surface 6 made of the second plastic is formed, and on the opposite groove walls of which shadow gap walls 7 are formed made of the second plastic, which is integrally bonded, preferably by coextrusion, to the first plastic of the base profile 2. These additional grooves 8 shown can be provided in any number, but do not have to be provided.

[0088] The Figure 2Avisualizes a detail of the first embodiment. Here, it can be seen that the shadow gap wall 7 is firmly attached to the vertically sloping wall region 2c of the base profile 2 near the receiving region 5, e.g., by coextrusion. Particularly preferably, the shadow gap wall 7 has a lower leg 7a at the lower end region, which extends toward the receiving groove 5a on the lower surface of the base profile 2.

[0089] Furthermore, the shadow gap wall 7 particularly preferably has a leg 7b at its upper end, which extends parallel to the surface 2a, in particular whose surface is flush with the surface 2a. In this embodiment, this applies to all shadow gap walls 7 of all shadow gaps of the facade cladding profile 1, regardless of whether the shadow gaps are initially present in the facade cladding profile 1 or are formed by plugging two profiles 1 together.

[0090] As a result, the respective shadow gap wall 7 forms an upper fastening surface that is larger than the normal wall thickness, to which the film can be attached as a surface coating 3, e.g., by adhesive bonding. The film can thus be applied to the surface 2a and the shadow gap wall 7 in the same plane or without any vertical offset.

[0091] The Figure 2Bshows the detail of the formation of an additional shadow gap at a groove 8 in the surface 2a of the base profile 2. Here, it can be seen that the entire inner surface of the outwardly visible shadow gap is made of the same second plastic. Shadow gap walls 7 and the shadow gap surface 6 are formed in one piece from the second plastic and are bonded, for example, by coextrusion, to the first plastic of the base profile 2. Here, too, the legs 7b can be seen on both shadow gap walls 7 in the upper end area, on which the film rests and is fastened. These legs 7b extend parallel and flush with the surface level of the base profile 2. This design according to Figure 2B is provided if the surface 2a is interrupted by at least one groove 8, but can otherwise be omitted.

[0092] The Figure 2Cshows the detail at the plug-in area 4. Here, it can be seen that the wall area 2b, which slopes downwards from the surface 2a toward the plug-in area 4 or the shadow gap surface 6, is formed with a shadow gap wall 7 made of the second plastic, which is bonded, for example, by coextrusion, to the first plastic of the base profile. Here, too, the leg 7b on which the film rests and is attached can be seen in the upper end area of ​​the shadow gap wall 7. This leg 7b extends parallel to and flush with the surface 2a of the base profile 2.

[0093] All such legs 7b, such as in the Figures 2A , 2B and 2C recognizable, extend from the respective shadow gap wall 7 and the shadow gap in the direction of the adjacent surface 2a.

[0094] In the Figure 2CIt can also be seen that the shadow gap surface 6, or rather the second plastic forming it, is designed to slope further toward the fastening area. This ensures that when inserted into a receiving area 5, its lower surface can run onto this area formed as a ramp.

[0095] When executing the Figures 2 The surface coating 3 is formed by a film that rests on the upper legs 7b of the shadow gap walls 7 at the shadow gaps and also ends there. Unlike in the prior art, the shadow gap wall 7 is therefore not coated with the film in the areas facing the interior of the shadow gap.

[0096] The Figure 3 shows a first alternative of a second embodiment and the Figures 3A-C show the details in the same places as before the Figures 2A to 2C The second plastic is shown here as a thick black line.

[0097] In comparison to the first embodiment, it is provided here that both the surface coating 3 and the shadow gap walls 7 and the shadow gap surface 6 of each individual shadow gap are formed integrally from this second plastic, which is bonded, e.g., by coextrusion, to the first plastic of the base profile 1. The appearance on the visible side is thus consistently determined by the second plastic.

[0098] Here, it can preferably be provided that the second plastic is mechanically structured in the area of ​​the surface coating 3, e.g. by brushing or embossing after coextrusion. On the side of the receiving area, which is in Figure 3A As can be seen, the shadow gap wall 7 has the lower leg 7b.

[0099] Although the surface regions 3 and the shadow gap walls 7 as well as the shadow gap surfaces 6 are all formed by the same second plastic, it can preferably be provided that the co-extruded regions of the surface coating 3 and the co-extruded regions 6, 7 of the shadow gap are produced by different co-extrusion nozzles, in particular wherein the melt of the second plastic is bonded in these different regions.

[0100] If the surface coating is formed in several surface areas separated by grooves 8, these can also be created by different extrusion nozzles.

[0101] It is also possible to provide for the formation of the surface coating and the shadow gaps with the second plastic using only a single coextrusion nozzle.

[0102] The Figures 4A to 4Cvisualize in the same detailed representations as the Figures 3A to 3C another alternative of the second version.

[0103] Here, it is provided that the surface coating 3 is formed from a third plastic which is materially bonded, e.g. by coextrusion, to the first plastic of the base profile 2 and which is also materially bonded, e.g. by coextrusion, to the second plastic of the shadow gap, in particular at the top of the upper region of the shadow gap wall 7.

[0104] Due to the simultaneous production of the surface coating 3 and the shadow gap wall 7 in a coextrusion, the previously described formation of an upper leg 7b on the shadow gap wall 7 can be omitted here, because the melts of the third and second plastics bond directly during the coextrusion. Figures 4A to 4CThe visible dividing lines between the surface coating 3 and the shadow gap wall 7 at its upper end visualize the separation between the third and second plastic, with a simultaneous material connection between these plastics.

[0105] In the statements of the Figures 4A to 4C Preferably, the third plastic for the surface coating 3 and the second plastic for the shadow gaps 6,7 are extruded through different coextrusion nozzles onto the base profile 2, which comes from another coextrusion nozzle.

[0106] The third plastic differs from the second, for example, by a different color pigmentation with the same plastic matrix or by a chemically different plastic, in particular one that is color pigmented.

[0107] In this embodiment, it can also be preferably provided that the third plastic in the area of ​​the surface coating 3 is mechanically structured, e.g. by brushing or embossing after coextrusion. On the side of the receiving area, which is in Figure 4A As can be seen, the shadow gap wall 7 has the already mentioned lower leg 7b.

[0108] If the third and second plastics were identical, the design would be as per the Figures 3 .

[0109] The Figure 5 visualizes designs of the respective shadow gap which can be preferably provided, regardless of whether this is created by plugging together or is originally present in the profile 1 and regardless of whether the surface coating 3 is designed as a film or as a co-extruded layer of the second plastic.

[0110] Here it can be seen that a respective shadow gap has a shadow gap surface 6 with a width b which is less than or equal to the width a of the shadow gap opening, in particular the shadow gap opening at the height of the surface 2a of the base body 2 or at the height of the surface coating 3. This results in a shadow gap which widens outwards.

[0111] Furthermore, preferably independently of the aforementioned embodiment or in combination with it, it can be provided that the opposing shadow gap walls 7 of a respective shadow gap present in the facade cladding profile or of a shadow gap formed by connecting two facade cladding profiles 1 are not arranged mirror-symmetrically about a plane lying perpendicular to the shadow gap surface and parallel to the longitudinal direction of the facade cladding profile. This results in the angles α and β shown here, which the surface coating 3 forms with the shadow gap wall 7 viewed as extended beyond it, being unequal. Preferably, the angle α, which points towards the plug-in area 4, is greater than the angle β. List of reference symbols
