Abstract

The facade cladding has a body of mineral wool, with the fiber alignment at right angles to its laying surface at the rear side. The visible surface is given a contoured structure by dry embossing. The mineral wool cladding (27) is produced in one or more layers (36,37), with the fibers standing upright. The outer surface of erect fibers is shaped by dry embossing, without added shape stabilizers or fluids. The embossing pressure forms depressed concave zones (26) where the fiber ends are either broken or shaped with an irreversible distortion. The broken/distorted fiber ends are compressed together at the outer surface of the material to give a smooth embossed pattern surface. The compressed zones have a density of 50-170 kg/m<3>. Before embossing, the fibers pass through an impregnation and hardening station to fix their alignment. A closed profile is worked into the surface areas where the embossing has imposed a concave surface structure, and an open profile can be embossed alongside. The cladding material production is continuous, using a mineral wool web passed through the processing stages. After embossing, the cladding material is cut to size and shape.

Description

Die Erfindung betrifft ein Verfahren zur Profilierung der Oberfläche eines Verkteidungsetementes mit Dämmeigenschaften.The invention relates to a method for profiling the surface of a Covering element with insulation properties.

Es ist bekannt, Dämmelemente oder auch Verkleidungselemente aus Mineralwolle zu fertigen und'deren Oberfläche zu profilieren. Bei einer derartigen Materialverwendung hat das Element eine Struktur mit horizontal zu seinen großen Flächen geordneten Mineralfasern. Bedingt durch die Struktur kommt es zum Nachfedern der horizontal geordneten Mineralfasern, auch bei einem hohen Bindemittelanteil und relativ großer Dichte. Damit eine Prägung der Oberfläche von dauerhafter Gestalt entstehen kann, werden deshalb Mineralfasern mit Bindemitteln vermischt, im feuchten, ungebundenen Zustand in Formen gegeben und darin verformt. Soll nur die Oberfläche des Produktes oberflächenstrukturiert werden, so wird auf diese Fläche des Elementes eine feuchte Schicht eines Fasermaterials oder Fasergemisches, vermengt mit Bindemitteln und Formstabilisatoren, aufgetragen, mit Prägewerkzeugen bearbeitet und danach einem Trocknungsvorgang unterzogen. Es ist auch bekannt, analog zu der dargestellten Technologie des mehrschichtigen Aufbaus solcher Elemente das gesamte Material des Elementes anzufeuchten, in eine Form zu geben, zu pressen und anschließend das Material verfestigend zu trocknen. Die DE 40 40 925 A1 offenbart ein Verfahren und eine Vorrichtung zum Herstellen von Formteilen aus ebenen Zuschnitten oder Vorformteilen aus mit Bindemitteln versehenen Zellulose oder Lignozellulose-Wirrfaservliesen. It is known to include insulation elements or cladding elements made of mineral wool finished and to profile their surface. With such a Using material, the element has a structure that is horizontal to its large size Ordered mineral fibers. Due to the structure it comes to Resilience of the horizontally arranged mineral fibers, even with a high one Binder content and relatively high density. So that an embossing of the surface of mineral fibers with binders can therefore be created in a permanent form mixed, put in molds in the moist, unbound state and in it deformed. If only the surface of the product is to be surface structured, so is a wet layer of a fiber material or on this surface of the element Fiber mixture, mixed with binders and shape stabilizers, applied with Embossing tools processed and then subjected to a drying process. It is also known, analogous to the technology of the multilayer shown Building such elements to moisten the entire material of the element into one Giving shape, pressing and then drying to solidify the material. DE 40 40 925 A1 discloses a method and an apparatus for manufacturing from molded parts from flat blanks or preforms from with binders provided cellulose or lignocellulosic non-woven fibers.

Analog zu dem bereits dargestellten bekannten Verfahren wird hier ein Wirrfaservlies durch Anwendung von Druck und Temperatur verwendet, bei dem das Vorformteil durch einen einseitig wirkenden Fluiddruck vollflächig gegen ein formgebendes Werkzeug verdichtet und ausgeformt wird. Das Verfahren weist den Nachteil auf, dass hier der gesamte Grundkörper verformt wird und nicht nur die Oberfläche eines zu strukturierenden Verkleidungs- oder Dämmelementes.Analogous to the known method already described here, a Tangled fiber fleece used by applying pressure and temperature, at which the Preform part against a full surface by a one-sided fluid pressure shaping tool is compressed and shaped. The procedure points the Disadvantage that the entire base body is deformed and not only that Surface of a cladding or insulation element to be structured.

Aus dem Patent Abstract of Japan zu JP 59111833A ist ein Verfahren bekannt, bei dem eine harzgebundene Faserplatte zunächst mit einer Dekorplatte belegt und anschließend durch eine Druckplatte profiliert wird.A method is known from the Patent Abstract of Japan for JP 59111833A which a resin-bonded fibreboard is first covered with a decorative panel and is then profiled by a pressure plate.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Profilierung der Oberfläche eines Verkleidungselementes mit Dämmeigenschaften zur Verfügung zu stellen, mit dem es möglich ist, Verkleidungs- und Dämmelemente unter Vermeidung einer Rückfederung des geprägten Profils trocken zu prägen.The invention has for its object a method for profiling the Surface of a cladding element with insulation properties available with which it is possible to avoid cladding and insulation elements a spring back of the embossed profile.

Erfindungsgemäß wird die Aufgabe durch das Verfahren nach Anspruch 1 gelöst.According to the invention the object is achieved by the method according to claim 1.

Demnach kann das Profil eins Verkleidungs- und Dämmelementes mittels eines, senkrecht auf die aufrecht zu der zu profilierenden Oberfläche stehenden Fasern gerichteten Druckes, ohne einen Zusatz von Formstabilisatoren sowie Flüssigkeiten, trockengeprägt werden, wobei die in konkav geprägten Bereichen des Profils, dem Druck des Prägewerkzeuges ausgesetzten Fasern und Faserbereiche, an der Oberfläche verbogen, gebrochen und so gerichtet werden, dass ihre Verformung irreversibel ausgebildet wird. Die Erfindung ist sinnvoll ausgebildet, wenn die irreversibel verformten und/oder gebrochenen Fasern und Faserbereiche in die geprägten Flächen, deren Oberflächenbereiche verdichtend eingepreßt werden und an den Prägestellen eine glatte, gleichmäßig verdichtete, mit einem Prägemuster ausgestattete Profilfläche auf dem Grundkörper erzeugt wird. Es ist eine Ausübungsform des erfindungsgemäßen Verfahrens, wenn die Prägung trocken, als Druckprofilierung der Oberflächen der Grundkörper der Verkleidungs- bzw. Dämmelemente in dem Dichtebereich des Materials von 50 kg/m3 bis 170 kg/m3 vorgenommen wird. Die Erfindung ist dadurch vorteilhaft ausgebildet, dass vorrangig die zur Prägung vorgesehene große Oberfläche des Faservlieses einer Bearbeitung unterzogen wird, mit welcher die Oberfläche glatt und ebenflächig auszubilden ist. Ein vorteilhafter Verfahrensschritt nach der Erfindung sieht vor, die zu profilierende Oberfläche des Efementes vor dem Prägen durch eine aushärtende Imprägnierung zu verfestigen. Das Verfahren gestaltet sich dadurch erfindungsgemäß vorteilhaft, dass die Profilierung durch einen senkrecht auf die zu prägende Oberfläche des Grundkörpers gerichteten Druck eines Prägewerkzeuge vorgenommen wird. Es ist eine Ausbildung der Erfindung, dass zur Profilierung der Oberfläche der Grundkörper Prägewerkzeuge benutzt werden, die plattenförmig oder walzenartig ausgebildet sind. Die erfindungsgemäße Lösung ist fortgeführt, indem die geprägte Oberfläche nach dem Profilieren einer oder mehrerer Imprägnierungen unterzogen wird. Ausgestaltend erhält das Produkt mit profilierter Oberfläche anschließend an die Imprägnierung ein oder mehrere Beschichtungen, die farbintensiv oder nichtfärbend sind und dem Produkt ein gefälliges, an seinen Verwendungszweck anpaßbares Aussehen verleiht. Nach einer Ausführungsform der Erfindung ist in die geprägte Oberfläche eines jeden Verkleidungselementes mit Dämmeigenschaften ein in sich abgeschlossenes Profil eingearbeitet. In Varianz zur erfindungsgemäßen Lösung kann in die geprägte Oberfläche eines jeden Verkleidungselementes mit zugeordneten Dämmeigenschaften ein in sich nicht abgeschlossenes, sich auf den daneben anzufügenden Elementen fortführendes Profil oder Muster aufgeprägt werden. Es ist für das Verfahren erfinderisch, dass die Verkleidungselemente mit den ihnen eigenen Dämmeigenschaften in einem kontinuierlichen Herstellungsprozeß, unter Verwendung eines ungeteilten, sich durch die Fertigungseinrichtung bewegenden Faservlieses geprägt und nach dem Prägen das Faservlies, entsprechend der Elementart, in beliebige Größen und Formate zerteilt werden.Accordingly, the profile of a cladding and insulation element can be dry-embossed by means of a pressure directed perpendicularly to the fibers standing upright to the surface to be profiled, without the addition of form stabilizers and liquids, the areas of the profile embossed in concave, the pressure of the embossing tool exposed fibers and fiber areas, bent on the surface, broken and straightened so that their deformation is irreversible. The invention is sensibly designed if the irreversibly deformed and / or broken fibers and fiber areas are pressed into the embossed surfaces, the surface areas of which are pressed in compactively and at the embossing points a smooth, uniformly compressed profile surface provided with an embossing pattern is produced on the base body. It is an embodiment of the method according to the invention if the embossing is carried out dry, as pressure profiling of the surfaces of the base body of the cladding or insulation elements in the density range of the material from 50 kg / m 3 to 170 kg / m 3 . The invention is advantageously designed in such a way that primarily the large surface of the nonwoven fabric intended for embossing is subjected to processing with which the surface is to be made smooth and flat. An advantageous method step according to the invention provides for the surface of the element to be profiled to be solidified by a hardening impregnation before embossing. The method is advantageous according to the invention in that the profiling is carried out by a pressure of an embossing tool directed perpendicularly to the surface of the base body to be embossed. It is an embodiment of the invention that embossing tools are used to profile the surface of the base body, which are plate-shaped or roller-shaped. The solution according to the invention is continued by subjecting the embossed surface to one or more impregnations after profiling. After the impregnation, the product with a profiled surface receives one or more coatings that are color-intensive or non-coloring and give the product a pleasing appearance that can be adapted to its intended use. According to one embodiment of the invention, a self-contained profile is incorporated into the embossed surface of each cladding element with insulating properties. In a variant of the solution according to the invention, a profile or pattern that is not self-contained and continues on the elements to be added can be embossed into the embossed surface of each cladding element with assigned insulation properties. It is inventive for the method that the cladding elements with their own insulating properties are embossed in a continuous manufacturing process, using an undivided nonwoven fabric that moves through the manufacturing device, and after embossing, the nonwoven fabric is divided into any sizes and formats according to the type of element ,

Die erfindungsgemäße Lösung weist den Vorteil auf, dass jetzt mit einem äußerst wirtschaftlichen Verfahren das Oberflächenprofil eines Verkleidungselementes mit hervorragenden Dämmeigenschaften in einem Trockenprägeverfahren hergestellt werden kann. Dem Fachmann ist sofort verständlich, dass damit eine signifikante Einsparung an Energie, Arbeitszeit und allgemeinen Fertigungskosten einhergeht. Das Verfahren gestattet es, Elemente zu prägen, deren Profil formkonstant bleibt, eine gleichmäßige Oberflächendichte sowie Rauhtiefe bei einer spürbaren Glätte seiner Oberfläche, auch in den konkav geformten Oberflächenteilen aufweist. Weil das Grundmaterial so variert werden kann, dass es erheblichen physikalischen Belastungen standhält ist es jetzt möglich, dem Material des Grundkörpers Strukturen und Materialarten zuzuordnen, die eine hohe Brandsicherheit gewährleisten. Neben den hohen dekorativen Eigenschaften, welche den Verkleidungselementen bei ihrer Anwendung als Decken- oder Wandverkleidungen zugemessen sind, verzeichnet die erfindungsgemäße Lösung den Vorteil, dass durch die erfindungsgemäße Einformung der Faserbestandteile, insbesondere in den merklich konkav geprägten Bereichen, eine gleichmäßig große Oberflächendichte und -glätte erhalten wird, die den Verkleidungselementen neben ihren hervorragenden akustischen Eigenschaften einen großen dekorativen Schauwert verleihen. Die bereits vorteilhaft erwähnte geringe Rauhtiefe der geprägten Oberflächen ist die Voraussetzung für eine wirksame, mit geringen Schichtdicken aufzutragende Oberflächenbeschichtung der Verkleidungselemente. Es ist nach der erfindungsgemäßen Lösung ein großer Vorteil, dass die bereits erwähnte geringe Rauhtiefe und gleichmäßig große Oberflächendichte der geprägten Oberflächen auch eine Verwendung der Elemente, unter Auslassen einer nachträglichen Beschichtung mit Farb- oder Lasurschichten möglich werden läßt, ohne deren Schauwert zu beeinträchtigen. Durch die lamellierte Struktur der mit ihren Fasern senkrecht orientierten Grundelemente entsteht ein wiederkehrendes, aus ästhetischer Sicht angenehmes Muster. Sollte es erforderlich sein, die Oberflächen zu beschichten, so brauchen die geprägten Bereiche nach dem Prägen nicht glättend behandelt werden. Ein als Vorteil herauszuhebender Verfahrensbestandteil ist darin zu sehen, dass die Herstellbarkeit großformatiger Platten mit durchgängiger oder partieller Prägung ebenso möglich ist, wie die Herstellung beliebiger Formen, Dimensionierungen und Ausführungsarten in Format und Oberflächenprägung der Elemente. Die erfindungsgemäßc Form der Prägung und Oberflächenausbildung der Verkleidungs- bzw. Dämmelemente ist vorteilhafterweise anhand von Grundelementen dargestellt, die zweischichtig, mit sich kreuzenden, stegartigen Lamellen ausgebildet sind. Diese Ausführungsform hat den Vorteil einer großen Formstabilität,
Verwindungssteifigkeit und hervorragenden Dämmwirkung. Sie wurde deshalb ausgewählt, da sie neben den guten statischen Eigenschaften den Prägedruck des Werkzeuges besser aufnehmen kann. So ist es vorteilhafterweise auch möglich, bei zweischichtig ausgebildeten Grundelementen die Schichtstärken in unterschiedlichen Mächtigkeiten anzuordnen. Auch ist es nicht ausgeschlossen, dass die untere Schicht einen Faserverlauf erhält, der parallel zu den großen Flächen des Elementes gerichtet ist. Vorteilhafterweise ist. es jetzt möglich, die untere Schicht mit einem Material zu versehen, das hohe Brandschutzeigenschaften aufweist und sehr hitzebeständig ist. Selbstverständlich erhalten die zu prägenden Verkleidungselemente eine erfindungsgemäß gleichwertig hohe Qualität, wenn sie innerhalb des Verfahrens mit Elementen ausgebildet werden, die einschichtig strukturiert sind, da sie in dieser einen Schicht die gleiche stegartige Lamellenausbildung mit einem senkrecht orientierten Faserverlauf aufweisen.The solution according to the invention has the advantage that the surface profile of a cladding element with excellent insulating properties can now be produced in a dry stamping process using an extremely economical process. The person skilled in the art immediately understands that this is associated with a significant saving in energy, working hours and general production costs. The process allows elements to be embossed whose profile remains constant in shape, has a uniform surface density and roughness with a noticeably smooth surface, even in the concave surface parts. Because the base material can be varied in such a way that it can withstand considerable physical loads, it is now possible to assign structures and types of material to the base body material that guarantee high fire safety. In addition to the high decorative properties which are assigned to the cladding elements when used as ceiling or wall cladding, the solution according to the invention has the advantage that the inventive molding of the fiber components, in particular in the noticeably concave areas, results in a uniformly large surface density and smoothness is obtained, which give the cladding elements, in addition to their excellent acoustic properties, a great decorative value. The low roughness depth of the embossed surfaces, which has already been mentioned advantageously, is the prerequisite for an effective surface coating of the cladding elements to be applied with small layer thicknesses. According to the solution according to the invention, it is a great advantage that the already mentioned low roughness and uniformly large surface density of the embossed surfaces also make it possible to use the elements while omitting a subsequent coating with color or glaze layers without impairing their visual value. The laminated structure of the basic elements with their fibers oriented vertically creates a recurring, aesthetically pleasing pattern. If it is necessary to coat the surfaces, the embossed areas need not be smoothed after the embossing. One part of the process to be highlighted as an advantage is the fact that it is possible to produce large-format panels with continuous or partial embossing, as well as to produce any shapes, dimensions and designs in terms of the format and surface embossing of the elements. The shape according to the invention of the embossing and surface formation of the cladding or insulation elements is advantageously illustrated on the basis of basic elements which are formed in two layers, with intersecting, web-like slats. This embodiment has the advantage of great dimensional stability,
Torsion resistance and excellent insulation. It was chosen because, in addition to the good static properties, it can better absorb the embossing pressure of the tool. In this way, it is advantageously also possible to arrange the layer thicknesses in different thicknesses in the case of two-layered basic elements. It is also not out of the question that the lower layer will have a fiber orientation that is parallel to the large areas of the element. It is advantageous. it is now possible to provide the lower layer with a material that has high fire protection properties and is very heat-resistant. Of course, the cladding elements to be embossed receive an equally high quality according to the invention if they are formed within the process with elements that are structured in one layer, since they have the same web-like lamella formation with a vertically oriented fiber course in this one layer.

Die Figuren 1 bis 5 zeigen zwei ausgewählte Lösungen geprägter und formatierter Verkleidungs- bzw. Dämmelemente 25;27. Das Prägemuster 26 bzw. die Prägungsart stellen eine Auswahl aus einer Vielzahl von Möglichkeiten dar. Sie sind deshalb ausgewählt worden, da hier einmal die Form eine heterogenen Prägung 26 und zum anderen, im zweiten Beispiel dargestellt, ein Muster ausgewählt wurde, das nicht bizarr, aber in sich abgeschlossen und mit anderen, sich anschließenden, gleichartigen Elementen 27 in eine sich flächenhaft ergänzende, in eine sich über das Element 27 hinaus erstreckende Wirkung gebracht ist. Fig. 1 zeigt ein quadratisches Element 25, dessen Oberfläche mit einer nicht harmonischen, bizarr ausgebildeten Prägung 26 versehen ist. Die zugehörige Fig. 2 zeigt in ihrer Schnittdarstellung, dass die Oberfläche 11 partiell tief eingeprägt und im rechten Randbereich flach eingeprägt ist. Dieses Element 25 eignet sich für einen dekorativ wirksamen Versatz von Bauwerksflächen oder anderen zu werkleidenen Flächen, bei denen sich das Muster in den anschließenden Platten nicht förtsetzt, sondern sich jedesmal wiederholt. Durch die lamellierte, stegartige Ausbildung der Schichten 36;37, mit der vorgenommen, kreuzförmigen Überlagerungen der so ausgebildeten Schichten 36;37, liegt jetzt ein Element 25 von grundsätzlich hoher Stabilität und Verwindungssteifigkeit vor. Durch das Prägen nur der oberen Schicht 36 bleibt die Stabilität des Grundelementes vollständig erhalten. Die erwähnte kreuzförmige Überlagerung des Grundkörpers des Elementes 25 ist geeignet, den spezifisch hohen Prägedruck des Werkzeuges, insbesondere bei einer Tiefenprägung aufzunehmen, ohne die Struktur und den inneren Zusammenhalt des Materials zu beeinträchtigen. Selbstverständlich ist es auch möglich, und das sieht der Fachmann beim Betrachten der Zeichnung , ein annähernd gleiches Vekleidungselement auch dann zu fertigen, wenn dieses nur aus einer, nicht kreuzgitterartig ausgebildeten Schicht des Grundelementes gefertigt ist.Figures 1 to 5 show two selected solutions embossed and formatted Cladding or insulation elements 25; 27. The embossing pattern 26 or the type of embossing represent a selection from a variety of possibilities. That is why they are were selected because here the form is a heterogeneous embossing 26 and another, shown in the second example, a pattern that was not selected bizarre but self-contained and with other, subsequent, similar elements 27 in a complementary area, in one over the Element 27 extending effect is brought. Fig. 1 shows a square Element 25, the surface of which is not harmonious, bizarre Embossing 26 is provided. The associated FIG. 2 shows in its sectional view, that the surface 11 is partially deeply embossed and flat in the right edge area is embossed. This element 25 is suitable for a decorative offset from building surfaces or other surfaces to advertising, where the Patterns in the subsequent panels do not continue, but each time repeated. Due to the laminated, web-like formation of the layers 36; 37, with the cross-shaped overlays of the layers thus formed 36; 37, there is now an element 25 of fundamentally high stability and Torsional stiffness. By embossing only the upper layer 36 that remains Stability of the basic element completely preserved. The cruciform mentioned Superposition of the base body of the element 25 is suitable, the specific high To emboss the die pressure of the tool, particularly in the case of deep embossing, without affecting the structure and internal cohesion of the material. Of course it is also possible, and the expert sees this when looking at it the drawing, to produce an approximately identical lining element, if this consists only of a layer of the Basic element is made.

Fig. 3 zeigt ein sechseckig formatiertes Verkleidungsetementes 27 mit Segmenten 28;29, die wechselnd in zwei Dreiergruppen geprägt sind. Für diese Gruppen sind die Segmente 28;29 ausgewählt worden, die im Element 27 je dreifach in gleichmäßiger Anordnung vorhanden sind. Das Segment 28 ist in seiner äußeren Randzone tiefer und in der inneren, dem Mittelpunkt angenäherten Zone, wenig geprägt. Das Segment 29 weist eine entgegengesetzte Prägungsform auf. Hier ist die äußere Randzone wenig und die Innere, dem Mittelpunkt zugewendete Randzone stark geprägt. Das Element 27 mit seinem Sechseckformat mit sechs Segmenten 28;29, aufgeteilt in zwei ungleiche Segmentgruppen, stellt ein Verkleidungselement dar, dessen Muster sich in dem an die Außenkanten angelegten Element 27 fortsetzt. Die Fig. 4 zeigt im Schnitt partiell die unterschiedlich geprägten Neigungen der Segmente 28;29. Dabei ist erkennbar, dass das Segment 29 mit seiner Außenkante nicht geprägt und das Segment 28 an seiner Außenkante erheblich geprägt ist. Die Prägung ist, da das Element aus zwei Schichten 36;37 geprägt ist, bis in die Nähe der unteren Schicht 37 geführt worden.Fig. 3 shows a hexagonally formatted cladding element 27 with segments 28; 29, which are alternately shaped in two groups of three. For these groups are the segments 28; 29 have been selected, each in the element 27 three times in uniform arrangement are present. The segment 28 is in its outer Edge zone deeper and in the inner zone approximating the center, little embossed. The segment 29 has an opposite embossing shape. Here is the little outer edge zone and the inner edge zone facing the center strongly shaped. Element 27 with its hexagon format with six segments 28; 29, divided into two unequal segment groups, represents a cladding element represents, whose pattern continues in the element 27 applied to the outer edges. 4 shows in section the differently shaped inclinations of the Segments 28; 29. It can be seen that the segment 29 with its outer edge not embossed and the segment 28 is significantly embossed on its outer edge. The Embossing is near since the element is embossed from two layers 36; 37 the lower layer 37 has been performed.
