Abstract

The device for making coverings (5) comprises a two-part mould (1, 2) which surrounds the contour of the covering (5). The surfaces (3, 4) forming the surround are perforated, and by means of at least one of these surfaces is formed a locked-off space (7) which can be connected to gases or vapours, heated if appropriate, or to a vacuum. <IMAGE>

Description

Gegenstand der Erfindung ist eine Vorrichtung zum Herstellen von multifunktionalen Verkleidungsteilen, die die Form eines Feder-Masse-Systems haben und aus durch Sperrschichten getrennten Vliesen verschiedener Dichte bestehen deren unterschiedliche Dichte durch die Einwirkung von Druck und Temperatur eingestellt wird.The invention relates to a device for producing multifunctional cladding parts which have the shape of a spring-mass system and consist of nonwovens of different densities separated by barrier layers, the different densities of which are set by the action of pressure and temperature.

Solche Verkleidungsteile werden zum Beispiel in Kraftfahrzeugen zum Verkleiden von Wänden und Böden verwendet wobei mit dieser Verkleidung eine Schalldämmung angestrebt wird. Für die Schalldämmung ist die Ausbildung als Feder-Masse-System sehr vorteilhaft.Such cladding parts are used, for example, in motor vehicles to clad walls and floors, with which cladding sound insulation is sought. Training as a spring-mass system is very advantageous for sound insulation.

Aus der EP 0 141 440 A2 ist es bekannt, doppelwandige Formkörper in einer Form herzustellen bei der von der Seite her erhitzte Gase oder Dämpfe in das zu bearbeitende Material eingeleitet werden. Aus diesem Grunde können mit der vorbekannten Form nur doppelwandige Formkörper hergestellt werden.From EP 0 141 440 A2 it is known to produce double-walled moldings in a mold in which gases or vapors heated from the side are introduced into the material to be processed. For this reason, only double-walled moldings can be produced with the previously known mold.

In der irischen Patentanmeldung No. 1552/90 vom 27. April 1990 ist ein Verfahren beschrieben worden mit dem durch Druck und Temperatur in einer Form zwei durch eine Sperrschicht getrennte Vliese annähernd gleicher Dichte derart verformt wrerden, daß die Sperrschicht zu dem einen Vlies hin geführt wird, wodurch dessen Dichte erhöht und die des anderen Vlieses vermindert wird. Derart bilden die beiden Vliese ein Feder-Masse-System.In Irish patent application no. 1552/90 of April 27, 1990, a method has been described by means of which pressure and temperature in a mold are used to deform two nonwovens of approximately equal density separated by a barrier layer in such a way that the barrier layer is led to the one nonwoven, thereby increasing its density and that of the other fleece is reduced. In this way, the two nonwovens form a spring-mass system.

Der Erfindung liegt die Aufgabe zugrunde eine Vorrichtung der eingangs beschriebenen Art anzugeben, mit der auch flächenhafte Verkleidungsteile mit unterschiedlichen Schichtfolgen hergestellt werden können.The invention is based on the object of specifying a device of the type described at the outset, with which areal covering parts with different layer sequences can also be produced.

Die die Lösung dieser Aufgabe ermöglichende Vorrichtung besteht erfindungsgemäß aus einer zweiteiligen Form deren beide Teile in Arbeitsstellung die Umriße des zu fertigenden Verkleidungsteiles einschließen, in den die die Umriße einschließenden Flächen in flächenhaft gleichmäßiger Verteilung Bohrungen aufweisen,
die einerseits in den Umriß des zu fertigenden Verkleidungsteiles und andererseits an mindestens einem der beiden Teile in einen abgeschlossenen Raum führen, in den Gas oder Dampf mit vorgegebener Temperatur eingeführt werden können oder in dem ein Vakuum erzeugt werden kann.The device which enables this object to be achieved consists, according to the invention, of a two-part form, the two parts of which, in the working position, include the contours of the trim part to be produced, in which the surfaces including the contours have bores with uniform distribution over the surface,
which lead on the one hand to the outline of the trim part to be manufactured and on the other hand to at least one of the two parts in an enclosed space into which gas or steam can be introduced at a predetermined temperature or in which a vacuum can be generated.

In einer Weiterbildung der Erfindung ist die Form der erfindungsgemäßen Vorrichtung beheizbar.In a development of the invention, the shape of the device according to the invention can be heated.

Die besonderen Vorteile und die vielseitige Verwendbarkeit der erfindungsgemäßen Vorrichtung werden anhand der Figuren erläutert.The particular advantages and the versatility of the device according to the invention are explained with reference to the figures.

In Figur 1 ist der obere Teil der Form mit 1 und der untere Teil mit 2 bezeichnet. Teil 1 umschließt mit der Fläche 3 und Teil 2 mit der Fläche 4 den Umriß des zu fertigenden Verkleidungsteiles 5. Die Flächen 3 und 4 weisen Bohrungen 6 auf, die gleichmäßig mit einem gegenseitigen Abstand von etwa 5o mm über die Flächen verteilt sind und einerseits in den Umriß des Verkleidungsteiles 5 führen während die Bohrungen in dem Teil 1 in einen abgeschlossenen Raum 7 führen zu dem eine abschließbare Leitung 8 führt. Durch die Leitung 8 können vortemperierte Gase oder Dämpfe in den Raum 7 und durch die Bohrungen 6 in der Fläche 3 in den Umriß des zu fertigenden Verkleidungsteiles 5 geführt werden. Die Bohrungen 6 in der Fläche 4 führen in den umgebenden freien Raum. Mit einer solchen Vorrichtung können Verkleidungsteile gemäß der oben genannten irischen Patentanmeldung gefertigt werden indem durch Einleitung von Gasen mit 6 - 10 bar und mit einer Temperatur von etwa 200 Grad C in den Raum 7 das untere Vlies 9 verdichtet und das obere Vlies 10 entsprechend gedehnt wird, sodaß ein Feder-Masse-System entsteht. Auch kann auf das Vlies 9 gemäß Figur 2 eine Dekorschicht 16 aufkaschiert werden, wenn die Dekorschicht soweit luftdurchlässig ist, daß sie die Kompression des Vlieses 9 nicht behindert oder mit entsprechen höherem Druck in dem Raum 7 gearbeitet wird.In Figure 1, the upper part of the mold with 1 and the lower part with 2 is designated. Part 1 encloses with the surface 3 and part 2 with the surface 4 the outline of the cladding part 5. The surfaces 3 and 4 have holes 6 which are evenly spaced about 5o mm apart over the surfaces and on the one hand in the outline of the trim part 5 lead while the holes in part 1 lead into a closed space 7 to which a lockable line 8 leads. Pre-heated gases or vapors can be led through the line 8 into the space 7 and through the holes 6 in the surface 3 into the outline of the trim part 5 to be produced. The holes 6 in the surface 4 lead into the surrounding free space. With such a device, trim parts can be manufactured according to the above-mentioned Irish patent application by compressing the lower fleece 9 and introducing the upper fleece 10 accordingly by introducing gases at 6-10 bar and at a temperature of about 200 degrees C into the space 7 , so that a spring-mass system is created. A decorative layer 16 can also be laminated onto the nonwoven 9 according to FIG. 2 if the decorative layer is air-permeable to the extent that it does not hinder the compression of the nonwoven 9 or the room 7 is operated with a correspondingly higher pressure.

Wenn der unter der Fläche 4 befindliche Raum 11 ebenso wie der Raum 7 abgeschlossen und mit einer Zuleitung wie bei 8 in Figur 1 versehen wird, kann auch ein Verkleidungsteil nach Figur 3 hergestellt werden. An der Fläche 3 liegt dann die luftdurchlässige Dekorschicht 12 an. Ihr folgt das erste gedehnte Vlies 13, das von dem verdichteten Vlies 14 durch eine nicht dargestellte erste Sperrschicht und von dem ebenfalls gedehnten Vlies 15 durch eine weitere, nicht dargestellte Sperrschicht getrennt ist. In diesen Fall wird das ursprünglich gleichdicke Schichtensystem von beiden Seiten mit Druck aus den Räumen 7 und 11 beaufschlagt sodaß sich das mittlere Vlies 14 zwischen den beiden Sperrschichten verdichtet und somit ein Feder-Masse-Feder-System entsteht.If the space 11 located under the surface 4, like the space 7, is closed and provided with a feed line as at 8 in FIG. 1, a covering part according to FIG. 3 can also be produced. The air-permeable decorative layer 12 then lies on the surface 3. It is followed by the first stretched fleece 13, which is separated from the compressed fleece 14 by a first barrier layer, not shown, and from the likewise stretched fleece 15 by a further barrier layer, not shown. In this case, the layer system, which was originally of the same thickness, is subjected to pressure from the rooms 7 and 11 from both sides, so that the middle fleece 14 between the two barrier layers is compressed, thus creating a spring-mass-spring system.
