Abstract

A surface covering has its underside next to the surface to be covered. Opposite the underside is the visible top side. This covering consists of a plastics material and is self-adhesive on its underside. The plastics material is in the form of a web which is self-adhesive on its underside. It can also take the form of a three-dimensional structure which is self-adhesive on its underside or of mutually independent pieces.

Description

Die Erfindung betrifft einen Belag für eine zu verkleidende Fläche, der sich mit seiner Unterseite auf der Fläche erstreckt und dessen der Unterseite gegenüberliegende Oberseite eine Sichtfläche darstellt.The invention relates to a covering for a surface to be covered, which extends with its underside on the surface and whose top opposite the underside represents a visible surface.

Derartige Beläge haben sich als Bodenbeläge gut bewährt. Die anfänglichen Befürchtungen, daß der selbsthaftende Belag nicht fest genug mit einem Boden verklammert werden könne, auf den der Belaq aufqebracht wird, haben sich als falsch erwiesen. Vielmehr haben sich die Hoffnungen bestätigt, daß derartige Beläge schnell und leicht verlegt werden können, so daß sie auch von Laien auf einen Boden aufgebracht werden können. Die verlegten Beläge zeigen weder die Tendenz, sich nach der Verlegung vom Boden wieder abzulösen,noch die bei anderen Verlegungen häufig beobachteten und immer wieder befürchteten Wellen.Such coverings have proven themselves well as floor coverings. The initial fears that the self-adhesive covering can not be clamped tightly enough with a bottom is aufqebracht elaq on the B have been proven wrong. Rather, the hopes have been confirmed that such coverings can be laid quickly and easily, so that they can also be applied to a floor by laypeople. The installed coverings show neither the tendency to come off the floor after installation, nor the waves that are frequently observed and feared in other installations.

Diese guten Erfolge hatten den Anlaß dazu gegeben, weitergehende Versuche mit selbsthaftenden Belägen anzustellen. Derartige Beläge konnten bisher nur auf einem glattgespachtelten Boden verlegt werden, damit sie weitflächig mit dem auf dem Boden aufgebrachten Kleber verhaftet werden konnten. Darüber hinaus hatten derartige, Beläge den Nachteil, daß sie im Regelfall aus einem relativ schwer verformbaren Kunststoff bestehen. Diese Kunststoffbahnen werden in Rollen verkauft. Sie nehmen bis zu ihrer Verlegung die Form dieser Rollen an und können daher nur mit erheblichen Aufwand den jeweiligen räumlichen Verhältnissen angepaßt werden, in denen die Bahn verlegt werden soll. Andererseits kommt mit dem auf den Boden bzw. auf die Rückseite der Bahn aufgebrachten Kleber eine relativ schnelle Verbindung zwischen dem Belag und dem Boden zustande, so daß nachträgliche Korrekturen im Zuschnitt nur noch sehr schwer auszugleichen sind. Gerade die Verlegung derartiger Bahnen war daher bisher nur einschlägigen Fachleuten vorbehalten, falls gewährleistet sein sollte, daß die Bahn ordnungsgemäß und ohne Verlegefehler verlegt werden sollte. Darüber hinaus bestanden derartige Bahnen sehr häufig aus Kunststoffen, die mit einigen der in Betracht zu ziehenden Kleber Verbindungen eingingen. Diese Verbindungen führten nicht selten dazu, daß die bereits verlegte Kunststoffbahn relativ schnell alterte und dadurch unansehnlich wurde. Auf die Auswahl des Klebers zum Zwecke der Verlegung derartiger Bahnen muß daher besondere Sorgfalt und einschlägige Fachkenntnis verwendet werden. Soweit derartige Voraussetzungen nicht erfüllt waren, wurden die verlegten Bahnen schnell unansehnlich und mußten ausgewechselt werden.These good successes had given rise to further tests with self-adhesive coverings. Until now, such coverings could only be laid on a smooth, leveled floor, so that they could be largely attached with the adhesive applied to the floor. In addition, such coverings had the disadvantage that they usually consist of a relatively difficult to deform plastic. These plastic sheets are sold in rolls. Until they are laid, they take the form of these rolls and can therefore only be adapted to the particular spatial conditions in which the web is to be laid with considerable effort. On the other hand, the adhesive applied to the floor or to the back of the web results in a relatively quick connection between the covering and the floor, so that subsequent corrections in the cut are very difficult to compensate for. Just laying Such sheeting has so far been reserved only for the relevant experts, if it should be ensured that the sheeting should be laid properly and without any laying errors. In addition, such sheets were very often made of plastics that bonded with some of the adhesives to be considered. These connections not infrequently led to the fact that the already laid plastic sheet aged relatively quickly and was therefore unsightly. Special care and relevant specialist knowledge must therefore be used when selecting the adhesive for the purpose of laying such sheets. If such conditions were not met, the laid tracks quickly became unsightly and had to be replaced.

Aufgabe der vorliegenden Erfindung ist es daher, den Belag der einleitend genannten Art so zu verbessern, daß er auf leichte Art und Weise auf die Fläche aufgebracht werden kann, ohne daß die Gefahr der Auswahl falscher Kleber besteht und daß der Belag relativ einfach der jeweiligen Bodengestaltung angepaßt werden kann.The object of the present invention is therefore to improve the covering of the type mentioned in the introduction so that it can be applied to the surface in a simple manner without the risk of selecting wrong adhesives and that the covering is relatively simple in relation to the respective floor design can be adjusted.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Belag aus Kunststoff besteht und auf seiner Unterseite selbsthaftend ausgebildet ist.This object is achieved in that the covering consists of plastic and is self-adhesive on its underside.

Ein derartiger Belag kann ohne erhebliche Schwierigkeiten unabhängig von seiner Konsistenz auf der jeweils zu verkleidenden Fläche befestigt werden. Diese Befestigung kann vorgenommen werden auf ebenen und auf unebenen Flächen. Der Kunststoff paßt sich nicht nur der Flächengestaltung an sondern klebt auch unabhängig von deren jeweiligerAusbildung. Die selbsthaftende Unterseite wird so ausgebildet, daß sie der jeweiligen Konsistenz des Kunststoffes entspricht. Bei besonders unflexiblen Kunststoffen wird ein schnell abbindender hochfester Kleber verwendet, während bei Kunststoffen, die leicht formbar sind, derartig hoher Ansprüche an die Haftkraft der selbsthaftenden Unterseite nicht gestellt werden müssen. Insbesondere im Hinblick auf die bereits aus der Hauptanmeldung bekannte Schutzfolie kann der Augenblick, in dem eine Verbindung zwischen der zu beklebenden Fläche und dem Belag zustande kommt, genau festgelegt werden. Dieser Augenblick tritt dann ein, wenn die Schutzfolie von der selbsthaftenden Unterseite abgezogen wird. Diese Abtrennung der Schutzfolie kann je nach dem Fortschritt der Verlegearbeiten kontinuierlich vorgenommen werden, so daß der Belag in kleinen Flächenabschnitten nach und nach mit der zu verkleidenden Fläche verklebt werden kann. Dieses langsam fortschreitende Verklebeverfahren zeigt seine Vorteile insbesondere dann, wenn der zu verlegende Belag besonders unflexibel ist und seine während seines Transportes angenommene Rollenform nicht gerne wieder aufgibt.Such a covering can be attached to the surface to be covered in each case without considerable difficulty, regardless of its consistency. This attachment can be done on flat and uneven surfaces. The plastic not only adapts to the surface design, but also sticks regardless of its respective design. The self-adhesive underside is designed so that it corresponds to the respective consistency of the plastic. With particularly un Flexible plastics use a fast-setting, high-strength adhesive, while plastics that are easy to form do not have to make such high demands on the adhesive force of the self-adhesive underside. In particular with regard to the protective film already known from the main application, the moment at which a connection is established between the surface to be glued and the covering can be precisely determined. This moment occurs when the protective film is removed from the self-adhesive underside. This separation of the protective film can be carried out continuously depending on the progress of the laying work, so that the covering can be gradually glued to the surface to be covered in small surface sections. This slowly progressing gluing process shows its advantages especially when the covering to be laid is particularly inflexible and does not like to give up the roll shape it took on during transport.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist der Kunststoff als eine auf ihre Unterseite selbsthaftende Bahn ausgebildet. Gerade bei der Verlegung derartiger Bahnen treten die bereits geschilderten Verlegeschwierigkeiten auf. Diese Bahnen besitzen große Flächen, die von Laien nur schwer der zu verkleidenden Fläche angepaßt werden können. Mit Hilfe der selbsthaftenden Unterseite können auch derartig große Flächen den Bedürfnissen der jeweils zu verkleidenden Fläche angepaßt werden. Auch lotrecht verlaufende Flächen können auf diese Weise leicht verkleidet werden. Die mit einer selbsthaftenden Unterseite ausgestatteten Bahnen können auch ohne Schwierigkeit an einer als Decke ausgebildeten Fläche befestigt werden,- ohne daß die Notwendigkeit besteht, die verkleidete Fläche auf Dauer einer Druckbelastung auszusetzen, die beispielsweise bei der Verkleidung von Böden durch schwere Möbelstücke oder ständiges Begehen der verkleideten Fläche erreicht wird.According to a preferred embodiment of the invention, the plastic is designed as a web that is self-adhesive on its underside. The laying difficulties already described occur particularly when laying such webs. These tracks have large areas that laypeople can hardly adapt to the area to be covered. With the help of the self-adhesive underside, such large areas can also be adapted to the needs of the area to be covered. Even perpendicular surfaces can be easily covered in this way. The sheets equipped with a self-adhesive underside can also be attached to a surface designed as a ceiling without difficulty, without the need to permanently expose the paneled surface to a pressure load For example, when covering floors by heavy pieces of furniture or constant walking on the clad surface.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausführlichen Beschreibung und den beigefügten Zeichnungen, in denen eine bevorzugte Ausführungsform der Erfindung beispielsweise veranschaulicht ist.Further details of the invention will become apparent from the following detailed description and the accompanying drawings, in which a preferred embodiment of the invention is illustrated, for example.

Ein Belag besteht im wesentlichen aus einer einer zu verkleidenden Fläche 1 benachbarten Unterseite 2, einer Schicht 3 aus Kunststoff sowie einer der Unterseite 2 im wesentlichen planparallel verlaufenden Oberseite 4. Die Unterseite 2 ist selbsthaftend ausgebildet. Diese Ausbildung kann dadurch herbeigeführt werden, daß der die Schicht 3 bildende Kunststoff im Bereich der Unterseite 2 selbsthaftende Eigenschaften aufweist. Darüber hinaus ist es jedoch auch denkbar, daß auf die Unterseite 2 eine selbsthaftende Schicht 4 aufgetragen wird. Diese selbsthaftende Schicht 4 kann beispielsweise aus einem Kunstharz bestehen. Bei dem Kunstharz kann es sich um einen Kleber, beispielsweise einen Schmelzkleber, einen Dispersionskleber oder einen lösungsmittelhaltigen Kleber handeln.A covering essentially consists of an underside 2 adjacent to a surface 1 to be clad, a layer 3 made of plastic and an upper side 4 running essentially plane-parallel. The underside 2 is self-adhesive. This design can be brought about by the fact that the plastic forming the layer 3 has self-adhesive properties in the area of the underside 2. In addition, however, it is also conceivable that a self-adhesive layer 4 is applied to the underside 2. This self-adhesive layer 4 can for example consist of a synthetic resin. The synthetic resin can be an adhesive, for example a hot melt adhesive, a dispersion adhesive or a solvent-containing adhesive.

Die Schicht 3 kann als eine Bahn 5 ausgebildet sein, die entsprechend der jeweiligen Ausgestaltung der Fläche 1 zugeschnitten wird, um die Bahn 5 gut deckend auf die Fläche 1 aufbringen zu können. Um diese Anpassung der Bahn 5 an die Fläche 1 vornehmen zu können, wird die Bahn 5 der Gestaltung der Fläche 1 entsprechend zugeschnitten. Während der Anpassung der Bahn 5 an die Fläche 1 ist die selbsthaftende Schicht 4 von einer Folie 6 abgedeckt, so daß die selbsthaftende Schicht 4 während des Zuschneidens ihre selbsthaftende Kraft nicht zum Nachteil dessen entwickeln kann, der den Zuschnitt vornimmt. Auf diese Weise soll verhindert werden, daß während des Anpassens der Bahn 5 an die Fläche 1 bereits eine Haftung zwischen der Bahn 5 und der Fläche 1 stattfindet. Außerdem sollen Teile der Schicht 3, die von der Bahn 5 abgeschnitten worden sind, nicht auf der Unterseite 2 fest haften.The layer 3 can be designed as a web 5, which is cut according to the respective configuration of the surface 1 in order to be able to apply the web 5 to the surface 1 in a well-covering manner. In order to be able to adapt the web 5 to the surface 1, the web 5 is cut according to the design of the surface 1. During the adaptation of the web 5 to the surface 1, the self-adhesive layer 4 is covered by a film 6, so that the self-adhesive layer 4 cannot develop its self-adhesive force during the cutting to the disadvantage of the person carrying out the cutting. In this way, it should be prevented that during the adaptation of the web 5 to the surface 1 there is already adhesion between the web 5 and the surface 1. In addition, parts of the layer 3 which have been cut off from the web 5 should not adhere firmly to the underside 2.

Die Folie 6 erstreckt sich planparallel zur Unterseite 2 und deckt die selbsthaftende Schicht 4 ab, so daß sich diese zwischen der Folie 6 und der Unterseite 2 erstreckt. Nach dem Zuschnitt der Bahn 5 kann die Folie 6 von der Unterseite 2 abgezogen werden, so daß nunmehr die Bahn 5 mit ihrer Unterseite 2 auf die Fläche 1 aufgeklebt werden kann.The film 6 extends plane-parallel to the underside 2 and covers the self-adhesive layer 4, so that it extends between the film 6 and the underside 2. After the web 5 has been cut, the film 6 can be removed from the underside 2, so that the web 5 can be glued to the surface 1 with its underside 2.

Die selbsthaftende Schicht 4 kann als eine zusammenhängende Schicht die gesamte Unterseite 2 bedecken. Darüber hinaus ist es möglich, sämtliche Ausführungsformen für die selbsthaftende Schicht zu wählen, die bereits aus der Hauptanmeldung bekannt sind. Insbesondere ist daran zu denken, die selbsthaftende Schicht in Form von gradlinigen Streifen 7, Streifen in ZickZack 8 und als einzelne selbsthaftende Punkte 9 auszubilden. In welcher Form die selbsthaftende Schicht auf die Unterseite 2 aufgebracht wird, hängt ab von der Art der Fläche 1, der Art des zur Herstellung der selbsthaftenden Schicht 4 verwendeten Klebers und dem Kunststoff, aus dem die Schicht 3 besteht. Beispielsweise hat sich zur Herstellung der selbsthaftenden Schicht 4 ein Kleber gut bewährt, der unter dem Einfluß von Wärme in der Lage ist, eine gute Klebverbindung zwischen der Fläche 1 und der Unterseite 2 herbeizuführen. Hinsichtlich der selbsthaftenden Ausbildung der Unterseite 2 wird auf die Merkmale der Hauptanmeldung verwiesen. Im wesentlichen ist daran zu denken, die Unterseite 2 der aus Kunststoff bestehenden Schicht 3 chemisch so zu behandeln, daß der Kunststoff im Bereich der Unterseite 2 klebende Wirkung entfaltet.The self-adhesive layer 4 can cover the entire underside 2 as a coherent layer. In addition, it is possible to choose all of the embodiments for the self-adhesive layer which are already known from the main application. In particular, it should be remembered to form the self-adhesive layer in the form of straight strips 7, strips in zigzag 8 and as individual self-adhesive points 9. The form in which the self-adhesive layer is applied to the underside 2 depends on the type of surface 1, the type of adhesive used to produce the self-adhesive layer 4 and the plastic from which the layer 3 is made. For example, for the production of the self-adhesive layer 4, an adhesive which has the ability to produce a good adhesive bond between the surface 1 and the underside 2 under the influence of heat has proven successful. With regard to the self-adhesive formation of the bottom 2, reference is made to the features of the main application. Essentially, it should be remembered to chemically treat the underside 2 of the layer 3 made of plastic so that the plastic has an adhesive effect in the area of the underside 2.

Es ist auch denkbar, ähnlich wie beim Fußbodenbelag der Hauptanmeldung die Unterseite 2 mit einer zusammenhängenden Schicht 4 zu bedecken, die selbsthaftende Wirkungen zeigt. Darüber hinaus können aus dieser selbsthaftenden Schicht 4 einzelne Punkte 10 herausragen, in deren Bereich die Schicht 3 besonders intensiv mit der Fläche 1 verhaftet. Zwischen den einzelnen Punkten 10 liegen Bereiche 11, die eine weniger intensive Haftung zeigen als im Bereich der Punkte 10.It is also conceivable, similarly to the floor covering of the main application, to cover the underside 2 with a coherent layer 4 which shows self-adhesive effects. In addition, individual points 10 can protrude from this self-adhesive layer 4, in the area of which layer 3 adheres particularly intensively to surface 1. There are areas 11 between the individual points 10 which show less intensive adhesion than in the area of points 10.

Diese Bereiche 11 erlauben eine Verschiebung der Schicht 3 auf der Fläche 1, wenn sich beispielsweise die Schicht 3 unter dem Einfluß von Wärme dehnt. Insbesondere bei einer räumlich gestalteten Schicht 3, wie sie beispielsweise in Figuren 4 und 5 dargestellt ist, kann eine derartige Ausgestaltung der selbsthaftenden Schicht 4 von großem Vorteil sein, um der räumlich gekrümmten Struktur der Fläche 1 gut abdeckend Rechnung tragen zu können.These areas 11 allow a shift of the layer 3 on the surface 1 if, for example, the layer 3 expands under the influence of heat. In particular in the case of a spatially designed layer 3, as is shown, for example, in FIGS. 4 and 5, such an embodiment of the self-adhesive layer 4 can be of great advantage in order to be able to take into account the spatially curved structure of the surface 1.

Schließlich ist es denkbar, die Schicht 3 in der Weise herzustellen, daß sie auf ihrer der selbsthaftenden Schicht 4 abgewandten Sichtfläche 12 mit einer besonders strapazierfähigen Abdeckung 13 versehen ist. Diese Abdeckung 13 kann aus einer besonders harten aber durchsichtigen Schicht bestehen. Es ist jedoch auch denkbar, die Schicht 3 im Bereich der Sichtfläche 12 durch eine entsprechende chemische oder physikalische Behandlung so hart zu gestalten, z.B. zu Glasieren, daß sie großen Beanspruchungen standhalten kann. Derartige Abdeckungen machen die gesamte Schicht 3 so biegesteif, daß ihre Verlegung auf einer entsprechend gestalteten Fläche 1 bisher besondere Schwierigkeiten bereitete. In den meisten Fällen reichten Verklebungen mit Hilfe von Doppelklebebändern nicht aus. Bei Verwendung flüssiger Klebstoffe bestand die Gefahr, daß derartige Schichten 3 sich von der verklebten Fläche 1 wieder hoch wölbten, ohne daß eine Verklebung mit der Fläche 1 zustande kam. Außerdem muß bei Verwendung derartiger Klebstoffe die Fläche 1 in besonders sorgfältiger Weise für die Verklebung vorbereitet werden, um sicher zu stellen, daß der Klebstoff in allen Bereichen der Unterseite 2 eine gleichmäßig gute Haftvermittlung zwischen der Fläche 1 und der Unterseite 2 herbeiführen konnte. Zu diesem Zwecke mußte die Fläche 1 sehr sorgfältig eingeebnet werden. Die mit einer selbsthaftenden Unterseite 2 versehenden Schichten 3 erfordern jedoch eine derartig sorgfältige Vorbereitung der Fläche 1 nicht. Die selbsthaftende Unterseite 2 paßt sich jeglichen Oberflächengestaltungen der Fläche 1 an, so daß mit der Fläche 1 eine gute Verbindung zustande kommt. Dabei ist es auch denkbar, den Belag auf einen alten bereits abgenutzten Fußbodenbelag aufzubringen, ohne daß dieser zuvor von der Fläche 1 entfernt werden muß. Trotz der Biegesteifigkeit des verwendeten Kunststoffes kommt auf der unebenen Fläche 1 eine gute Haftung zwischen der Unterseite 2 und der Fläche 1 zustande.Finally, it is conceivable to produce the layer 3 in such a way that it is provided with a particularly hard-wearing cover 13 on its visible surface 12 facing away from the self-adhesive layer 4. This cover 13 can consist of a particularly hard but transparent layer. However, it is also conceivable to make the layer 3 in the area of the visible surface 12 so hard by means of a corresponding chemical or physical treatment, for example glazing, that it can withstand great stresses. Such covers make the entire layer 3 so rigid that their laying on an appropriately designed surface 1 has previously been particularly difficult. In most cases, double-sided adhesive tapes were not sufficient. When using liquid adhesives, there was a risk that such layers 3 would bulge up again from the bonded surface 1 without the surface 1 being bonded. In addition, when using such adhesives, the surface 1 must be prepared in a particularly careful manner for the gluing in order to ensure that the adhesive was able to bring about a uniformly good adhesion between the surface 1 and the underside 2 in all areas of the underside 2. For this purpose, area 1 had to be leveled very carefully will. However, the layers 3 provided with a self-adhesive underside 2 do not require such careful preparation of the surface 1. The self-adhesive underside 2 adapts to any surface configuration of the surface 1, so that a good connection is achieved with the surface 1. It is also conceivable to apply the covering to an old, already worn floor covering without this having to be removed from the surface 1 beforehand. Despite the flexural rigidity of the plastic used, good adhesion between the underside 2 and the surface 1 is achieved on the uneven surface 1.

Eine Ausbildung des Belages in Form von einzelnen Flächenstücken 14 dient beispielsweise der Verkleidung von Innenräumen von Kraftfahrzeugen. Derartige Beläge sind sehr häufig einer hohen Verschmutzung ausgesetzt, so daß sie zweckmäßigerweise von Zeit zu Zeit von der Fläche 1 abgenommen und gesäubert werden müssen. In diesen Fällen muß damit gerechnet werden, daß die Beläge sich trotz sorgsamer Behandlung verformen. Trotz derartiger Verformungen reicht die Beschichtung der Unterseite mit einer selbsthaftenden Schicht 4 aus, um die Flächenstücke 14 fest mit der Fläche 1 verbinden zu können.An embodiment of the covering in the form of individual surface pieces 14 serves, for example, to trim the interiors of motor vehicles. Such coverings are very often exposed to high levels of contamination, so that they need to be removed and cleaned from surface 1 from time to time. In these cases, it must be expected that the coverings will deform despite careful handling. Despite such deformations, the coating of the underside with a self-adhesive layer 4 is sufficient to be able to firmly connect the surface pieces 14 to the surface 1.

Die selbsthaftende Schicht 4 kann unmittelbar auf die Schicht 3 aufgebracht werden. Dabei muß darauf geschtet werden, daß die selbsthaftende Schicht 4 eine gute Verbindung mit der Schicht 3 herbeiführt. Aus diesem Grunde müssen der die Schicht 3 bildende Kunststoff und ein die selbsthaftende Schicht 4 beispielsweise bildender Kleber chemisch aufeinander abgestimmt sein. In solchen Fällen, in denen eine derartige Abstimmung nicht herbeigeführt werden kann, ist es denkbar, zwischen der selbsthaftenden Schicht 4 und der Schicht 3 eine Zwischenschicht 15 vorzusehen, die einerseits zu einer befriedigenden Verbindung mit der Schicht 3 führt und andererseits in der Lage ist, die selbsthaftende Schicht 4 aufzunehmen. Dabei muß darauf geachtet werden, daß die Zwischenschicht 15 mit einer guten Adhäsion auf der Schicht 3 haftet, um zu verhindern, daß die Zwischenschicht 15 sich von der Schicht 3 ablöst. Andererseits muß auch zwischen der selbsthaftenden Schicht 4 und der Zwischenschicht 15 sowohl eine gute Adhäsion als auch eine gute Verträglichkeit bestehen. Darüber hinaus muß die Zwischenschicht 15 eine große mechanische Festigkeit besitzen, um die zum Festhalten des Belages notwendigen Kräfte auf die Fläche 1 übertragen zu können. Schließlich ist daran zu denken, daß die Zwischenschicht 15 dazu beiträgt, Unebenheiten in den benachbarten Oberflächen der Schicht 3 einerseits und der selbsthaftenden Schicht 4 andererseits auszugleichen. Zum Zwecke dieses Ausgleiches wird die Zwischenschicht 15 beispielsweise auf die Schicht 3 aufgewalzt. Die Zwischenschicht 15 kann aus Fasern, beispielsweise einem Vließ bestehen. Die Dicke dieses Vließes beträgt etwa 1,5 mm.The self-adhesive layer 4 can be applied directly to the layer 3. Care must be taken that the self-adhesive layer 4 establishes a good connection with the layer 3. For this reason, the plastic forming the layer 3 and an adhesive forming the self-adhesive layer 4, for example, must be chemically matched to one another. In such cases in which such coordination cannot be brought about, it is conceivable to separate between the self-adhesive layer 4 and to provide layer 3 with an intermediate layer 15 which, on the one hand, leads to a satisfactory connection with layer 3 and, on the other hand, is able to absorb the self-adhesive layer 4. Care must be taken to ensure that the intermediate layer 15 adheres to the layer 3 with good adhesion in order to prevent the intermediate layer 15 from detaching from the layer 3. On the other hand, there must also be good adhesion as well as good compatibility between the self-adhesive layer 4 and the intermediate layer 15. In addition, the intermediate layer 15 must have a high mechanical strength in order to be able to transmit the forces required to hold the covering to the surface 1. Finally, it should be remembered that the intermediate layer 15 helps to compensate for unevenness in the adjacent surfaces of the layer 3 on the one hand and the self-adhesive layer 4 on the other. For the purpose of this compensation, the intermediate layer 15 is rolled onto the layer 3, for example. The intermediate layer 15 can consist of fibers, for example a fleece. The thickness of this fleece is about 1.5 mm.

Der die Schicht 3 bildende Kunststoff kann beispielsweise aus einem Thermoplast bestehen. Es ist jedoch auch denkbar, zu diesem Zwecke Duroplaste zu verwenden. Von einer besonders guten Oberflächenhärte ist die Schicht 3, wenn sie aus einem Polyvenylchlorid besteht. Derartige PVC-Beläge haben daher eine weite Verbreitung gefunden. Dem Polyvenylchlorid können Mischungsbestandteile zugemischt werden, beispielsweise kann dem PVC Asbest hinzugemischt werden.The plastic forming the layer 3 can consist, for example, of a thermoplastic. However, it is also conceivable to use thermosets for this purpose. Layer 3 has a particularly good surface hardness if it consists of a polyvinyl chloride. Such PVC coverings have therefore found widespread use. Mixing components can be mixed into the polyvinyl chloride, for example asbestos can be mixed into the PVC.
