Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer schallabsorbierenden Wandplatte nach dem Oberbegriff des Patentanspruchs.The invention relates to a method for producing a sound-absorbing wall panel according to the Generic term of the claim.

Die Herstellung einer schallabsorbierenden Wandverkleidung aus einer Träger-Faserplatte und einem Überzug aus teppichartigem Material, der mittels einer auf der Träger-Faserplatte angeordneten, nicht kontinuierlichen Klebeschicht mit derselben verbunden ist, ist bereits aus der DE-AS 23 56 081 bekannt. Dabei sind in der Oberfläche der Träger-Faserplatte mehrere Öffnungen vorgesehen. Auf dem Überzug zur Verbindung mit der Klebeschicht sind Klebstoffpunkte angeordnet. Dabei wird dafür gesorgt, daß von der Klebeschicht keine Öffnungen in der Träger-Faserplatte bedeckt werden. Bei der Verbindung der Träger-Faserplatte mit dem Überzug aus teppichartigem Material ergibt sich dann, daß die meisten Öffnungen in der Träger-Faserplatte von den Klebstoffpunkten unbedeckt bleiben.The production of a sound-absorbing wall cladding from a carrier fiber board and a Cover made of carpet-like material, which is arranged by means of a non-continuous Adhesive layer is connected to the same, is already known from DE-AS 23 56 081. In the surface of the carrier fiberboard provided several openings. On the cover to connect with glue dots are arranged on the adhesive layer. It is ensured that the adhesive layer no openings in the fibreboard support are covered. When connecting the carrier fiberboard with the covering of carpet-like material then results in most of the openings in the carrier fiberboard remain uncovered by the glue points.

Es hat sich jedoch gezeigt, daß der Aufwand zum Offenhalten der Öffnungen in der Träger-Faserplatte beim Aufbringen der Klebeschicht auf die Träger-Faserplatte sehr groß ist.It has been shown, however, that the effort to keep the openings in the carrier fiberboard open when applying the adhesive layer to the carrier fiberboard is very large.

Die der Erfindung zugrunde liegende Aufgabe besteht deshalb darin, das Verfahren nach dem Oberbegriff des Patentanspruchs 1 so auszubilden, daß das Aufbringen der Klebstoffschicht auf die Träger-Faserplatte ohne Verschließen der darin vorgesehenen Öffnungen auf einfache Weise ausgeführt werden kann. Diese Aufgabe wird durch die Merkmale aus dem kennzeichnenden Teil des Patentanspruchs gelöstThe object underlying the invention is therefore the method according to the Form the preamble of claim 1 so that the application of the adhesive layer on the carrier fiber board can be carried out in a simple manner without closing the openings provided therein. This object is achieved by the features from the characterizing part of the patent claim

Das erfindungsgemäße Verfahren hat den Vorteil, daß der Klebstoff mit einem einfachen Beschichtungsverfahren, wie es beispielsweise das Walzenbeschichtungsverfahren ist, auf die Träger-Faserplatie aufgebracht werden kann, wobei aufgrund der Gestaltung der Träger-Faserplattenoberfläche infolge der Prägung sichThe method according to the invention has the advantage that the adhesive can be coated with a simple coating process, as it is, for example, the roller coating process, applied to the carrier fiber board can be, due to the design of the support fiberboard surface as a result of the embossing

ίο der Klebstoff nur auf den erhabenen Bereichen ablagert Der Klebstoff hat eine ausreichend hohe Viskosität so daß er auf den aufgebrachten erhabenen Bereichen verbleibt und nicht in die vertieften Bereiche gelangt Aufgrund der dadurch auf der Träger-Faserplatte erzielten diskontinuierlichen Klebstoffbeschichtung bleiben die in der Träger-Faserplatte ausgebildeten Öffnungen im wesentlichen frei, so daß nach der Verbindung mit den auf die Rückseite des Teppichmaterials aufgebrachten Klebstoffpunkten die freien öffnungen in der Träger-Faserplatte akustisch wirksam werden können. Die Klebstoffbeschichtung der erhabenen Bereiche kann relativ dick ausgeführt werden. Die zwischen den erhabenen Bereichen verbleibenden vertieften Bereiche tragen ebenfalls zur Schal labsorplion bei. Die Prägung der Oberfläche der Faserplatte kann durch mechanisches Prägen, jedoch auch bereits bei der Naßablage des Faserplattenmaterials mittels eines Siebes erreicht werden.ίο the adhesive only deposits on the raised areas The adhesive has a sufficiently high viscosity that it can be applied to the raised areas remains and does not get into the recessed areas due to the result on the carrier fiberboard The discontinuous adhesive coating obtained remains those formed in the carrier fiberboard Openings essentially free so that after connection with the on the back of the carpet material Applied points of adhesive the free openings in the carrier fiberboard acoustically effective can be. The adhesive coating of the raised areas can be made relatively thick. the Depressed areas remaining between the raised areas also contribute to the scarf labsorplion at. The surface of the fiberboard can be embossed by mechanical embossing, but also already can be achieved by means of a sieve when the fibreboard material is wet deposited.

Anhand der Zeichnung, die einen Ausschnitt aus einer nach dem erfindungsgemäßen Verfahren hergestellten schallabsorbierenden Wandplatte zeigt, wird die Erfindung näher erläutert.Based on the drawing, which shows a section of a produced by the method according to the invention shows sound-absorbing wall panel, the invention is explained in more detail.

Die Wandplatte 2 besteht aus einer Faserplatte 4, deren Oberfläche mit nicht gezeigten schallabsorbieren-The wall panel 2 consists of a fiberboard 4, the surface of which with sound-absorbing, not shown

den Öffnungen versehen und derart geprägt ist, daß erhabene Bereiche und vertiefte Bereiche ausgebildet werden. Auf die erhabenen Bereiche ist eine Klebstoffbeschichtung 8 aufgebracht. Ein Teppichmaierial 6 ist an seiner unregelmäßig gestalteten Rückseite mit Klebstoffpunkten versehen. Beim Aufbringen des Teppichmaterials 6 auf die Faserplatte 4 ergeben sich Verbindungspunkte mit der Klebstoffbeschichtung 8, die derart verteilt sind, daß die nicht gezeigten schallabsorbierenden Öffnungen in der Faserplatte 4 im wesentlichen frei von Klebstoff sind und ebenso wie die vertieften Bereiche zwischen den Verbindungspunkten zur Absorption des durch das Teppichmaterial 6 hindurchgegangenen Schalls beitragen. Die erhabenen Bereiche der Faserplatte 4 haben gewöhnlich einenthe openings and is embossed such that raised areas and recessed areas are formed will. An adhesive coating 8 is applied to the raised areas. A carpet maierial 6 is on its irregularly shaped back with glue dots Mistake. When the carpet material 6 is applied to the fiber board 4, the result is Connection points with the adhesive coating 8, which are distributed in such a way that those not shown sound-absorbing openings in the fiberboard 4 are essentially free of adhesive and just like the recessed areas between the connection points for the absorption of the carpet material 6 contribute to the sound that has passed through. The raised areas of the fiberboard 4 usually have one

so Abstand von 10 mm, wobei der Höhenunterschied zwischen den erhabenen Bereichen und den vertieften Bereichen etwa 1,6 mm beträgt.so distance of 10 mm, being the difference in height between the raised areas and the recessed Areas is about 1.6 mm.
