Abstract

To produce a needled non-woven material, with two layers of different materials, the second layer is placed on the previously-prepared first layer and the two are needle-bonded together. The first layer is relatively thick, and the second layer is thinner and of the more expensive material. The material combinations include waste wool and sheep's wool, sheep's wool and camel hair, waste wool and camel hair, or waste wool and a mixture of sheep's wool and camel hair. ADVANTAGE - Intended mainly for mfg. matresses, the method gives a product of materials such as sheep's wool and other wool waste to give thermal insulation and permeability with lower material costs.

   BESCHREIBUNG



   Die Erfindung betrifft ein Verfahren zur Herstellung eines mindestens zweilagigen Nadelvlieses, insbesondere eines Wollvlieses, mit zwei Lagen unterschiedlichen Materials, insbesondere für die Herstellung von Matratzen.



   Bei der Herstellung von Matratzen wird der Matratzenkörper in der Regel mit einem Wollvlies versehen. Ein solches Wollvlies sorgt für die nötige Wärmeisolation und ist auch in der Lage, Luftfeuchtigkeit aufzunehmen bzw. abzugeben. Schafwolle ist jedoch ein relativ teures Material, so dass solche Matratzen, welche einen hohen Komfort bieten, relativ teuer sind. Seit einiger Zeit findet bei der Matratzenherstellung auch sogenannte Krauswolle Verwendung.



  Krauswolle ist ein Abfallprodukt der Wollverarbeitung. Sie wird durch Aufbearbeitung von Wollresten in einer Wollreisserei gewonnen. Besonders beliebt ist eine Kombination von zwei Vliesen, nämlich einem relativ dicken Vlies aus Krauswolle und einem darübergelegten relativ dünnen Vlies aus Schafwolle. Nachteilig ist jedoch dabei, dass es nicht einfach ist, das dünne Vlies auf dem dicken Vlies aufzulegen. Wird nämlich etwas zu stark gezogen, so entstehen dünne Stellen oder gar Löcher im dünnen Vlies. Dadurch wird die Qualität der Matratze beeinträchtigt.



   Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung eines mindestens zweilagigen Nadelvlieses, insbesondere eines Wollvlieses, mit zwei Lagen unterschiedlichen Materials zu schaffen.



   Gemäss der Erfindung wird dies dadurch erreicht, dass zuerst eine erste Materiallage gebildet und dann über der ersten Materiallage eine zweite Materiallage gebildet wird und die beiden Materiallagen gemeinsam vernadelt werden.



  Dadurch entsteht ein einheitliches Vlies, dessen Lagen aus z. B. Schafwolle und Krauswolle miteinander vernadelt sind und überall eine gleichmässige Stärke aufweisen.



   Die Erfindung betrifft auch eine Anlage zur Durchführung des Verfahrens, mit einer Wollkrempel, einem Flachleger und einer Nadelmaschine. Diese Anlage ist gekennzeichnet durch eine zweite Wollkrempel und einen zweiten Flachleger für die Verarbeitung einer anderen Materialqualität und einer Transportvorrichtung zum Transport des Vlieses aus dem ersten Flachleger zum zweiten Flachleger.



  Diese Anlage ermöglicht daher die problemlose Anordnung der zweiten Materiallage über der ersten Materiallage, worauf dann die Vernadelung durch die Nadelmaschine erfolgen kann.



   Die Erfindung betrifft auch ein Nadelvlies, das gekennzeichnet ist durch eine relativ dicke Lage aus einem ersten Fasermaterial und einer relativ dünnen Lage aus einem zweiten Fasermaterial. Zweckmässigerweise wird die relativ dicke Lage aus Krauswolle und die relativ dünne Lage aus Schafwolle gebildet. Möglich ist jedoch auch beispielsweise eine Kombination von Schafwolle und Kamelhaar oder von Krauswolle und Kamelhaar. Statt Kamelhaar könnte aber auch beispielsweise eine Mischung von Schafwolle und Kamelhaar für die relativ dünne Lage verwendet werden.



   Schliesslich betrifft die Erfindung die Verwendung des Nadelvlieses zur Matratzenherstellung. Durch diese Art von Nadelvlies wird die Matratzenherstellung erheblich verbilligt und vereinfacht.



   Ein Ausführungsbeispiel der Erfindung wird nun unter Bezugnahme auf die Zeichnung beschrieben. Es zeigt:
Fig. 1 eine schematische Darstellung eines Ausführungsbeispiels der Anlage,
Fig. 2 einen Schnitt durch ein Nadelvlies, das mit der Anlage gemäss Figur 1 hergestellt wurde.



   Bei der Anlage von Figur 1 wird beispielsweise Krauswolle durch die Wollkrempel 11 verarbeitet. Mit dem Flor von der Wollkrempel 11 wird durch den Flachleger 13 ein Vlies gebildet, das durch die Transporteinrichtung 15 zum Flachleger 17 transportiert wird. Dort wird über dem Vlies aus Krauswolle ein zweites Vlies gebildet durch den Flor von der Wollkrempel 19. Dieser Flor besteht beispielsweise aus Schafwolle oder Kamelhaar. Die beiden übereinanderliegenden Vliese 14, 18 (Fig. 2) werden nun zusammen von der Transporteinrichtung 15 durch die Nadelmaschine 21 geführt und vernadelt, so dass sie ein einheitliches Vlies bilden. Durch die Schneidmaschine 23 wird das Nadelvlies 22 (Fig. 2) auf die für die Matratzenherstellung gewünschte Grösse geschnitten. 



  
 



   DESCRIPTION



   The invention relates to a method for producing an at least two-layer needle punch fleece, in particular a wool fleece, with two layers of different materials, in particular for the manufacture of mattresses.



   When manufacturing mattresses, the mattress body is usually covered with a wool fleece. Such a wool fleece provides the necessary heat insulation and is also able to absorb or release air humidity. However, sheep's wool is a relatively expensive material, so those mattresses that offer a high level of comfort are relatively expensive. For some time, so-called weft wool has also been used in the manufacture of mattresses.



  Kraus wool is a waste product from wool processing. It is obtained by processing wool remnants in a wool mill. A combination of two fleeces is particularly popular, namely a relatively thick fleece made of weft wool and a relatively thin fleece made of sheep's wool overlaid on top. However, it is disadvantageous that it is not easy to place the thin fleece on the thick fleece. If something is pulled too hard, thin spots or even holes will appear in the thin fleece. This affects the quality of the mattress.



   It is therefore an object of the present invention to provide a method for producing an at least two-layer needle punch fleece, in particular a wool fleece, with two layers of different material.



   According to the invention, this is achieved by first forming a first layer of material and then forming a second layer of material over the first layer of material and needling the two layers of material together.



  This creates a uniform fleece, the layers of z. B. sheep wool and weft wool are needled together and have a uniform thickness everywhere.



   The invention also relates to a system for carrying out the method, with a wool card, a flat lay and a needle machine. This system is characterized by a second wool card and a second flat layer for processing a different material quality and a transport device for transporting the fleece from the first flat layer to the second flat layer.



  This system therefore enables the second material layer to be arranged without problems above the first material layer, whereupon the needling can then be carried out by the needle machine.



   The invention also relates to a needle felt, which is characterized by a relatively thick layer made of a first fiber material and a relatively thin layer made of a second fiber material. The relatively thick layer is expediently formed from weft wool and the relatively thin layer from sheep wool. However, a combination of sheep's wool and camel hair or of curly wool and camel hair is also possible, for example. Instead of camel hair, for example, a mixture of sheep's wool and camel hair could also be used for the relatively thin layer.



   Finally, the invention relates to the use of the needle felt for the manufacture of mattresses. This type of needle felt makes the manufacture of mattresses considerably cheaper and easier.



   An embodiment of the invention will now be described with reference to the drawing. It shows:
1 is a schematic representation of an embodiment of the system,
Fig. 2 shows a section through a needle fleece, which was produced with the system according to Figure 1.



   In the system of FIG. 1, for example, weft wool is processed by the wool card 11. With the pile of the wool card 11 a fleece is formed by the flat layer 13, which is transported to the flat layer 17 by the transport device 15. There, a second fleece is formed over the fleece made of wispy wool by the pile of the wool card 19. This pile consists, for example, of sheep wool or camel hair. The two superposed nonwovens 14, 18 (FIG. 2) are now guided and needled together by the transport device 15 through the needling machine 21, so that they form a uniform nonwoven. The needle punch 22 (FIG. 2) is cut to the size desired for the manufacture of mattresses by the cutting machine 23.
