Description

Die Erfindung betrifft ein Verfahren zur Herstellung von durch seitliche Verbindungsmittel miteinander verbindbaren flächigen Elementen, insbesondere Bodenelementen, sowie eine Vorrichtung zur Durchführung des vorgenannten Verfahrens.The invention relates to a method for the production of connectable by lateral connecting means planar elements, in particular floor elements, and a device for carrying out the aforementioned method.

Derartige flächige Elemente werden beispielsweise zur Herstellung von Parkett- und Laminatfussböden verwendet, die sowohl in gewerblichen als auch in privaten Räumen weit verbreitet sind. Parkett- oder Laminatfussböden bestehen aus mehreren Einzelelementen, die entlang ihrer Seiten aneinandergesetzt und miteinander verbunden sind. Als seitliche Verbindungsmittel wird gewöhnlich eine entlang der Seiten ausgebildete Nut/Feder-Profilierung verwendet, die die einzelnen Bodenelemente zusammenhält. Auch ist eine Verklebung entlang der Seiten üblich. Als weitere Möglichkeit ist bekannt, die einzelnen Bodenelemente durch Klammern zusammenzuhalten, die gewöhnlich an ihrer Unterseite angeordnet sind.Such sheet-like elements are used for example for the production of parquet and laminate floors, which are widely used in both commercial and private spaces. Parquet or laminate floors are made up of several individual elements which are placed against each other along their sides and connected to each other. As a lateral connecting means usually along the sides formed groove / tongue profiling is used, which holds the individual floor elements together. Also a bonding along the sides is common. As a further possibility is known, the individual floor elements held together by clips, which are usually arranged on their underside.

Aus WO 2004/015221 A1 ist eine Anordnung von lösbar verbindbaren Bauteilen bekannt, die durch Verbindungsmitteln, insbesondere einschnappbare Verbindungsmittel gebildet wird. Hierbei besteht mindestens eines der Verbindungsmittel aus einem anderen Material als das jeweilige Bauteil. Dadurch ist es möglich, für die Bauteile wie auch für die Verbindungsmittel, im Hinblick auf die Anforderungen und Kosten optimale Werkstoffe unabhängig voneinander auszuwählen.Out WO 2004/015221 A1 an arrangement of detachably connectable components is known, which is formed by connecting means, in particular einschnappbare connecting means. In this case, at least one of the connecting means consists of a different material than the respective component. This makes it possible for the components as well as for the connecting means to select optimal materials in terms of requirements and costs independently.

Die EP 1 207 246 A1 beschreibt eine dekorative Laminat-Fußbodenplatte, welche eine dekorative Oberflächenschicht, eine hintere Schicht und ein zwischen diesen beiden Schichten angeordnetes Substrat umfasst Die Oberflächenschicht und das Ende des Substrats definieren eine Ausnehmung, in welcher ein Bauteil angeordnet ist. Dieses Bauteil besitzt ein nach außen gerichtetes Profil zum Verbinden mit benachbarten Laminat-Fußbodenplatten.The EP 1 207 246 A1 describes a decorative laminate floorboard comprising a decorative surface layer, a back layer, and a substrate disposed between these two layers. The surface layer and the end of the substrate define a recess in which a component is disposed. This component has an outwardly directed profile for connection to adjacent laminate floorboards.

Die in der WO 2004/016877 A1 offenbarte Erfindung betrifft eine Verkleidungsplatte für Fußböden, die längs zumindest eine Kante, eine Nut und längs zumindest einer anderen Kante eine Feder aufweist. Die Querschnitte der Nut und der Feder sind aneinander angepasst und miteinander durch Einführen der Feder in die Nut zu verbundenen Platten verbindbar.The in the WO 2004/016877 A1 The invention disclosed relates to a floor cladding panel having a spring along at least one edge, a groove and along at least one other edge. The cross sections of the groove and the spring are adapted to each other and connectable to each other by inserting the spring into the groove to connected plates.

Ein Verfahren zur Herstellung von längslaufenden Profilen wie Nut und Feder z.B. bei Fußbodenplatten ist in der WO 02/060691 A1 beschrieben. In diesem Verfahren werden folgende Schritte durchgeführt: Formen eines wesentlichen Teils des Profilquerschnitts durch Fräsen und Formen eines Hinterschnitts in mindestens einer Vertiefung des Profils durch Räumen.A process for the production of longitudinal profiles such as tongue and groove, for example, in floor panels is in the WO 02/060691 A1 described. In this method, the following steps are performed: forming a substantial part of the profile cross section by milling and forming an undercut in at least one recess of the profile by broaching.

Für viele Anwendungen wie insbesondere die Herstellung von Parkett- und Laminatfussböden besteht das Erfordernis einer Hydrophobierung, um das Eindringen von Feuchtigkeit zu verhindern, und/oder einer Geräuschminderung bzw. -dämpfung, insbesondere wenn die einzelnen Elemente noch eine Restbeweglichkeit aufweisen und durch eine äußere Krafteinwirkung beaufschlagt werden. Bisher konnte diesen Erfordernissen - wie insbesondere bei der Parkett- und Laminatfußbodenherstellung - erst nach Herstellung der flächigen Elemente oder gar nach Verlegen und Verbinden der flächigen Elemente durch nachträgliche Bearbeitung Rechnung getragen werden; eine solche Nachbearbeitung ist jedoch aufwendig und somit teuer.For many applications, such as in particular the manufacture of parquet and laminate floors, there is a need for hydrophobing to prevent the ingress of moisture, and / or a noise reduction or damping, in particular if the individual elements still have a residual mobility and by an external force be charged. So far, these requirements - as in particular in the production of parquet and Laminatfußboden - only after production of the sheet-like elements or even after laying and joining the sheet-like elements by subsequent processing account; Such post-processing is complicated and therefore expensive.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Herstellung von flächigen Elementen und eine entsprechende Vorrichtung anzugeben, wobei eine aufwendige Nacharbeitung der flächigen Elemente vermieden werden kann.Object of the present invention is therefore to provide a method for the production of sheet-like elements and a corresponding device, wherein a complex reworking of the sheet-like elements can be avoided.

Deshalb schlägt die Erfindung ein Verfahren zur Herstellung von durch seitliche Verbindungsmittel miteinander verbindbaren flächigen Elementen, insbesondere Bodenelementen, vor, welches die Schritte aufweist,

  1. a) in einem im Wesentlichen massiven flächigen Basismaterial, vorzugsweise längliche, Aussparungen vorzusehen,
  2. b) in die Aussparungen aushärtbare Masse in fließfähigem Zustand einzufüllen und dann dort im Wesentlichen aushärten zu lassen, und
  3. c) das Basismaterial entlang den mit der gehärteten Masse gefüllten Aussparungen zu zerschneiden und dadurch die gehärtete Masse als seitliches Verbindungsmittel freizulegen.
Therefore, the invention proposes a method for the production of surface elements which can be connected to one another by means of lateral connection means, in particular floor elements, which comprises the steps of
  1. a) to provide recesses in a substantially solid sheet-like base material, preferably elongate,
  2. b) to fill in the recesses curable mass in a flowable state and then to let it substantially harden, and
  3. c) to cut the base material along the recesses filled with the hardened mass and thereby expose the hardened mass as a lateral bonding agent.

Demnach verlangt das erfindungsgemäße Verfahren die Verwendung einer pastösen Masse, die von einem fließfähigen Zustand in einen ausgehärteten Zustand überführbar ist und zur Bildung der seitlichen Verbindungsmittel im fließfähigen Zustand in die Aussparungen gegossen wird. Nach Aushärtung der Masse in den Aussparungen wird die Anordnung aus Basismaterial und gehärteter Masse entlang den Aussparungen zerschnitten, und zwar gewöhnlich etwa entlang der Mittellinie der Aussparungen, um dadurch die gehärtete Masse als so gebildetes seitliches Verbindungsmittel freizulegen.Accordingly, the method according to the invention requires the use of a pasty mass which can be converted from a flowable state into a cured state and is poured into the recesses in the flowable state to form the lateral connection means. After the mass has set in the recesses, the array of base material and hardened mass is cut along the recesses, usually about along the center line of the recesses, thereby exposing the hardened mass as a lateral connecting means thus formed.

Die Erfindung erlaubt, bereits während der Herstellung der flächigen Elemente die seitlichen Verbindungsmittel so auszubilden, dass diese bestimmte Anforderungen erfüllen, in denen sie sich vom Basismaterial unterscheiden. So ist insbesondere denkbar, eine aushärtbare Masse mit hydrophoben und/oder geräuschmindernden Eigenschaften und/oder mit einer größeren Härte im ausgehärteten Zustand als die des Basismaterials zur Bildung eines verstärkten Seitenrandes und/oder mit einer bestimmten Einfärbung zu verwenden. Schließlich eignet sich das erfindungsgemäße Verfahren für eine zuverlässige Großserienfertigung.The invention allows the lateral connecting means to be formed already during the production of the flat elements in such a way that they meet certain requirements in which they differ from the base material. Thus, it is particularly conceivable to use a curable composition having hydrophobic and / or noise-reducing properties and / or having a greater hardness in the hardened state than that of the base material to form a reinforced side edge and / or to use a certain coloration. Finally, the inventive method is suitable for reliable mass production.

An dieser Stelle sei erwähnt, dass sich die Begriffe "Seite" und "seitlich" auf den umlaufenden Seitenrand eines fertigen flächigen Elementes oder zumindest einen Abschnitt eines solchen Seitenrandes beziehen.It should be mentioned at this point that the terms "side" and "side" refer to the circumferential side edge of a finished sheet-like element or at least a portion of such a side edge.

Vorzugsweise können im Schritt a) die Aussparungen zur Aufnahme der aushärtbaren Masse als Nuten in das Basismaterial eingearbeitet werden.Preferably, in step a), the recesses for receiving the hardenable mass can be incorporated as grooves in the base material.

Ferner ist es denkbar, im Schritt a) die Aussparungen im Basismaterial im Wesentlichen über dessen gesamte Dicke bzw. Tiefe auszubilden, wobei es von Vorteil ist, dass die Aussparungen an ihrer Unterseite von einer Unterlage begrenzt werden, die nach Aushärtung der Masse entfernt wird.Furthermore, it is conceivable to form the recesses in the base material substantially over its entire thickness or depth in step a), wherein it is advantageous that the recesses are delimited on their underside by a base, which is removed after hardening of the mass.

Gewöhnlich weist das Basismaterial Holz auf. Unter "Holz" sind alle Arten von Holzwerkstoffen und somit beispielsweise auch Holzfaserwerkstoffe zu verstehen.Usually the base material has wood. Under "wood" are all types of wood-based materials and thus for example, wood fiber materials to understand.

Eine weitere bevorzugte Ausführung der Erfindung zeichnet sich aus durch einen den Schritt c) folgenden Schritt

  • d) dem aus der freiliegenden gehärteten Masse gebildeten seitlichen Verbindungsmittel, vorzugsweise durch spanabhebende Bearbeitung, eine für einen Eingriff mit einem seitlichen Verbindungsmittel eines anderen flächigen Elementes geeignete Form zu geben.
A further preferred embodiment of the invention is characterized by a step following step c)
  • d) to give the lateral connecting means formed from the exposed hardened mass, preferably by machining, a suitable shape for engagement with a lateral connecting means of another flat element.

Zweckmäßigerweise erhält das seitliche Verbindungsmittel des einen flächigen Elementes eine zur Form des seitlichen Verbindungsmittels des anderen flächigen Elementes komplementäre Form. Dabei sollte eine gewöhnliche Nut/Feder-Profilierung gewählt werden, indem in das seitliche Verbindungsmittel des einen flächigen Elementes eine Nut eingearbeitet und aus dem seitlichen Verbindungsmittel des anderen flächigen Elementes eine komplementäre Feder herausgearbeitet wird.Conveniently, the lateral connecting means of a flat element receives a shape complementary to the shape of the lateral connecting means of the other planar element. In this case, an ordinary tongue / groove profiling should be selected by incorporating a groove in the lateral connecting means of a flat element and a complementary spring is machined out of the lateral connecting means of the other flat element.

Wenn eine Applikation für eine Hydrophobierung, Geräuschminderung und/oder Rastkantenverstärkung und/oder ein bestimmter optischer Eindruck gefordert wird, ist eine Masse mit hydrophoben und/oder geräuschmindernden Eigenschaften und/oder guten Härteeigenschaften im ausgehärteten Zustand und/oder bestimmten Einfärbungen entsprechend zu verwenden.If an application for a hydrophobization, noise reduction and / or locking edge reinforcement and / or a certain visual impression is required, a mass with hydrophobic and / or noise-reducing properties and / or good hardness properties in the cured state and / or certain colorations is to be used accordingly.

Üblicherweise sollte die aushärtbare Masse Kunststoffmaterial aufweisen. Vorteilhaft ist, wenn die aushärtbare Masse durch Erwärmung schmelzfähig wird.Usually, the curable composition should comprise plastic material. It is advantageous if the hardenable mass is melted by heating.

Zweckmäßigerweise sollte als aushärtbare Masse ein Thermoplast verwendet werden, das beide zuvor genannten Eigenschaften in sich vereint.Conveniently, should be used as a curable composition, a thermoplastic, which combines both aforementioned properties in itself.

Eine besonders einfache Möglichkeit, mindestens zwei flächige Elemente miteinander zu verbinden, bietet ein weiterer Schritt,

  • e) mindestens ein von der gehärteten Masse gebildetes seitliches Verbindungsmittel an mindestens einem flächigen Element kurzzeitig zu erwärmen und dadurch mit der Seite des anderen flächigen Elementes zu verschmelzen.
A particularly simple way of connecting at least two planar elements together offers a further step,
  • e) for a short time to heat at least one side connecting means formed by the hardened mass on at least one sheet-like element and thereby to fuse with the side of the other sheet-like element.

Eine Weiterbildung dieser Ausführung zeichnet sich dadurch aus, dass im Schritt e) die sich gegenüberliegenden von der gehärteten Masse gebildeten seitlichen Verbindungsmittel an den beiden zu verbindenden flächigen Elementen kurzzeitig erwärmt und dadurch miteinander verschmolzen werden.A further development of this embodiment is characterized in that, in step e), the opposite side connecting means formed by the hardened mass are briefly heated at the two flat elements to be connected and thereby fused together.

Eine weitere gegenwärtig besonders bevorzugte Ausführung des erfindungsgemäßen Verfahrens zeichnet sich dadurch aus, dass vor dem Schritt c) auf die Oberseite des Basismaterials eine Deckfolie aufgebracht wird, die die mit der gehärteten Masse gefüllten Aussparungen überdeckt und im Schritt d) zusammen mit dem Basismaterial zerschnitten wird. Diese Ausführung eignet sich insbesondere für die Applikation von Dekorfolien bei der Herstellung von Bodenelementen.Another currently particularly preferred embodiment of the method according to the invention is characterized in that before the step c) on the top of the base material, a cover sheet is applied, which covers the filled with the cured mass recesses and is cut in step d) together with the base material , This embodiment is particularly suitable for the application of decorative films in the manufacture of floor elements.

Schließlich kann in oder nach dem Schritt d) die gehärtete Masse an ihrem oberen Rand angefast werden, wodurch nach Verbindung der flächigen Elemente kleine Fugen entstehen.Finally, in or after step d), the hardened mass can be chamfered at its upper edge, resulting in small joints after connection of the flat elements.

Schließlich schlägt die Erfindung noch eine Vorrichtung zur Durchführung des zuvor beschriebenen Verfahrens gemäß Anspruch 16 vor.Finally, the invention also proposes a device for carrying out the method described above according to claim 16.

Weitere bevorzugte Ausführungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Further preferred embodiments of the invention are specified in the dependent claims.

Nachfolgend wird die Herstellung eines Bodenelementes beschrieben, das vorzugsweise für die Bildung von Parkett- oder Laminatfussböden verwendet wird. Selbstverständlich kann das nachfolgend beschriebene Verfahren aber auch für die Herstellung von anderen flächigen Elementen für andere Anwendungszwecke verwendet werden.The production of a floor element will be described below, which is preferably used for the formation of parquet or laminate floors. Of course, the method described below can also be used for the production of other sheet-like elements for other applications.

Für das herzustellende Bodenelement wird im beschriebenen Ausführungsbeispiel plattenförmiges Basismaterial 2 verwendet, wie Figur 1 zeigt. Dieses Basismaterial, das auch als Trägermaterial bezeichnet wird, besteht gewöhnlich aus Holz und insbesondere aus Holzfaserwerkstoffen. Wie Figur 1 ferner erkennen lässt, werden von der Oberseite 2a des Basismaterials 2 her in den Bereichen der späteren Zuschnittsägung längliche Nuten 4 eingearbeitet.For the bottom element to be produced plate-shaped base material 2 is used in the described embodiment, such as FIG. 1 shows. This base material, which is also referred to as a carrier material consists usually made of wood and especially of wood fiber materials. As FIG. 1 can also be seen, elongated grooves 4 are incorporated from the top 2a of the base material 2 forth in the areas of the subsequent blanking.

Diese Nuten 4 werden in einem weiteren Schritt, dessen Ergebnis in Figur 2 dargestellt ist, mit pastöser Masse 6 gefüllt, die durch Erwärmung in einen fließfähigen Zustand und durch Abkühlung in einen gehärteten Zustand überführbar ist. Ferner sollte die pastöse Masse in ihrem ausgehärteten Zustand hydrophobe und/oder geräuschmindernde Eigenschaften und/oder gute Härteeigenschaften im ausgehärteten Zustand und/oder bestimmte Einfärbungen aufweisen, wenn eine Hydrophobierung, Geräuschminderung, Rastkantenverstärkung und/oder ein besonderer optischer Eindruck gefordert wird.These grooves 4 are in a further step, the result in FIG. 2 is shown filled with pasty mass 6, which can be converted by heating in a flowable state and by cooling in a cured state. Furthermore, the pasty mass in its cured state should have hydrophobic and / or noise-reducing properties and / or good hardness properties in the cured state and / or certain colorations, if a hydrophobization, noise reduction, locking edge reinforcement and / or a special visual impression is required.

Durch Aushärtung der Masse 6 werden in den Nuten 4 aus dieser Masse bestehende massive leistenförmige Verstärkungselemente gebildet, die in das umgebende Basismaterial 2 eingebunden sind.By curing of the mass 6 existing massive strip-shaped reinforcing elements are formed in the grooves 4 from this mass, which are integrated into the surrounding base material 2.

Nach Aushärtung der pastösen Masse 6 in den Nuten 4 wird auf die Oberseite 2a des Basismaterials 2 sowie die Oberseite der ausgehärteten Masse 6 in den Nuten 4 eine Deckfolie 8 aufgetragen, wie Figur 3 zeigt. Die Deckfolie 8 wird vorzugsweise aufgeklebt bzw. auflaminiert. Bei der Deckfolie 8 kann es sich insbesondere um eine Dekorfolie handeln, wenn wie im beschriebenen Ausführungsbeispiel Bodenelemente für Parkett- oder Laminatfussböden hergestellt werden sollen.After curing of the pasty mass 6 in the grooves 4 is applied to the top 2a of the base material 2 and the top of the cured mass 6 in the grooves 4, a cover sheet 8, such as FIG. 3 shows. The cover film 8 is preferably glued or laminated. The cover film 8 may in particular be a decorative film if, as in the exemplary embodiment described, floor elements for parquet or laminate floorings are to be produced.

Anschließend findet eine Zuschnittsägung statt, und zwar im Bereich der Mittellinie der Nuten 4. Figur 4, in der die Situation nach der Zuschnittsägung gezeigt ist, lässt erkennen, dass im Bereich der Nuten das Basismaterial 2 und die gehärtete Masse sowie die Deckfolie 8 durchtrennt sind, um einzelne plattenförmige Bodenelemente 10 zu bilden. Dadurch, dass durch die Zuschnittsägung die gehärtete Masse 6 in den Nuten 4 geteilt wird, ist sie nun an den Seitenrändern der so gebildeten Bodenelemente 10 mit ihren Abschnitten 6a bzw. 6b freigelegt, die jeweils eine leistenförmige Verstärkung bilden, wie Figur 4 ebenfalls erkennen lässt.Subsequently, a blanking takes place, in the region of the center line of the grooves. 4 FIG. 4 in which the situation is shown after the blanking, can be seen that in the region of the grooves, the base material 2 and the cured mass and the cover sheet 8 are severed to form individual plate-shaped bottom elements 10. Characterized in that the hardened mass 6 is divided in the grooves 4 by the blanking, it is now exposed at the side edges of the floor elements 10 thus formed with their sections 6a and 6b, each forming a strip-shaped reinforcement, such as FIG. 4 also shows.

Anschließend werden die Seitenränder der Bodenelemente 10 gefräst, um den freiliegenden Abschnitten 6a, 6b der gehärteten Masse eine Nut/Feder-Profilierung zu geben, wie Figur 5 zeigt. Auf diese Weise entstehen komplementäre Verbindungsmittel 12a, 12b an den gegenüberliegenden Seiten der Bodenelemente 10.Subsequently, the side edges of the bottom members 10 are milled to give the exposed portions 6a, 6b of the hardened mass a tongue / groove profiling, such as FIG. 5 shows. In this way, complementary connecting means 12 a, 12 b are formed on the opposite sides of the floor elements 10.

Durch die Ausbildung der komplementär geformten Verbindungsmittel 12a und 12b ist es nun möglich, dass bei Verlegung eines Parkett- oder Laminatfussbodens das eine seitliche Verbindungsmittel 12a des einen Bodenelementes in das komplementäre seitliche Verbindungsmittel 12b eines benachbarten Bodenelementes 10 eingreift, um beide Bodenelemente 10 verrastend miteinander zu verbinden. Diese Verbindung ist in Figur 6 dargestellt.By forming the complementary shaped connecting means 12a and 12b, it is now possible that when laying a parquet or laminate floor, the one lateral connection means 12a of a bottom element engages in the complementary lateral connecting means 12b of an adjacent floor element 10 to lock both floor elements 10 to each other connect. This connection is in FIG. 6 shown.

Zusätzlich ist es auch noch möglich, die in der zuvor beschriebenen Weise verbundenen seitlichen Verbindungsmittel 12a und 12b zu erwärmen, wodurch die die seitlichen Verbindungsmittel 12a, 12b bildende Masse 6a und 6b miteinander verschmolzen wird. Auf diese Weise entsteht eine durchgängige, einheitliche und somit auch hydrophobe Verbindung zweier benachbarter Bodenelemente 10.In addition, it is also possible to heat the side connecting means 12a and 12b connected in the manner described above, whereby the masses 6a and 6b forming the lateral connecting means 12a, 12b are fused together. In this way, a continuous, uniform and thus also hydrophobic connection of two adjacent floor elements 10 is created.

Schließlich sei noch angemerkt, dass die seitlichen Verbindungsmittel 12a, 12b während oder nach dem zuvor anhand von Figur 5 beschriebenen Fräsvorgang an ihrer oberen Kante benachbart zur Oberseite 2a des Basismaterials 2 bzw. zur Deckfolie 8 angefast werden, wodurch im verbundenen Zustand jeweils zwischen zwei benachbarten Bodenelementen 10 eine kleine Fuge 14 entsteht, wie Figur 6 erkennen lässt.Finally, it should be noted that the lateral connecting means 12a, 12b during or after the previously with reference to FIG. 5 described milling process at its upper edge adjacent to the top 2a of the base material 2 and the cover sheet 8 are chamfered, whereby in the connected state between each two adjacent floor elements 10, a small gap 14 is formed, such as FIG. 6 lets recognize.
