Schichten unter Wärmeeinwirkung.·Layers under the influence of heat.

Ein nach dem Verfahren unter 1. hergestellter Schichtwerkstoff weist eine gute Gas- und Luftdurchlässigkeit auf, seine Herstellung ist aber ziemlich zeitraubend und außerdem muß damit gerechnet werden, daß die Steppnähte im Laufe der Zeit aufgehen. Bei einem nach dem Verfahren unter 2. hergestellten Schichtwerkstoff sind die auf- oder angeschmolzenen Stellen der schmelzbaren Schicht mit den entsprechenden Stellen der im allgemeinen aus faserigem Gut bestehenden nichtschmelzbaren Schicht verbunden. Die Gasdurchlässigkeit dieses Schichtwerkstoffs ist ausreichend, er weist aber keine genügende Haftung zwischen den einzelnen Schichten auf. Bei einem nach dem Verfahren unter 3. hergestellten Schichtwerkstoff erstreckt sich der Klebstoff über die ganze Grenzfläche zwischen der nichtschmelzbaren und der schmelzbaren Schicht, wodurch eine sehr stabile Verbindung erreicht wird. Ein so hergestellter Schichtwerkstoff ist allerdings ungesund, da er keine Gasdurchlässigkeit aufweist. Außerdem wird zu seiner Herstellung mehr Klebstoff verbraucht als eigentlich benötigt, wodurch er unwirtschaftlich ist.A layer material produced according to the method under 1. has good gas and air permeability, but its manufacture is rather time consuming and In addition, it must be expected that the stitching will open over time. With one after the procedure The layer material produced under 2. are the fused or fused areas of the fusible layer connected to the corresponding points of the non-meltable layer, which generally consists of fibrous material. The gas permeability of this layer material is sufficient, but it does not have sufficient adhesion between each layer. In the case of a layer material produced according to the method under 3. extends the adhesive spreads over the entire interface between the non-meltable and the meltable layer, whereby a very stable connection is achieved. However, a layered material produced in this way is unhealthy because it has no gas permeability. In addition, more adhesive is used to produce it than is actually needed, making it uneconomical.

Der Erfindung liegt die Aufgabe zugrunde, einen aus schmelzbaren und nichtschmelzbaren Schichten In beliebiger Kombination hergestellten Schichtwirkstoff mit guter Atmungsaktivität oder Gasdurchlässigkeit und sehr fester Haftung zwischen den einzelnen Schichten zu schaffen. Der Schichtwirkstoff soll außerdem einfach und wirtschaftlich herzustellen sein.The invention is based on the object of providing a combination of fusible and non-fusible layers manufactured laminate with good breathability or gas permeability and very strong adhesion to create between layers. The laminate should also be simple and economical to produce be.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die nichtschmelzbare Schicht mit der schmelzbaren Schicht durch ein die nichtschraelzbare Schicht mindestensAccording to the invention, this object is achieved in that the non-meltable layer with the meltable Layer by at least one non-touchable layer

einseitig durchtränkendes schmelzbares Material verklebt ist, derart, daß die unverklebten Stellen gasdurchlässig sind. Die durch Druckeinwirkung verklebten Stellen sind 'zweckmäßigerweise unter Ausbildung eines ansprechenden Musters über den Schichtwerkstoff verteilt und außerdem hohlraumfrei, während die unverklebten Stellen eine die Gasdurchlässigkeit gewährleistende Anzahl von Hohlräumen aufweisen.Fusible material that is soaked on one side is glued is such that the unglued areas are gas-permeable. The areas stuck by pressure are 'Expediently distributed over the layer material with the formation of an attractive pattern and also void-free, while the non-glued areas have a number of voids ensuring gas permeability exhibit.

Gemäß der Erfindung wird ein solcher Schichtwerkstoff in einfacher Weise nach einem Verfahren hergestellt, bei welchem mindestens eine schmelzbare und mindestens eine nichtschmelzbare Schicht unter Druckeinwirkung miteinander verklebt werden, und das sich dadurch auszeichnet, daß eine Folie eines schmelzbaren Materials auf eine Oberfläche einer nichtschmelzbaren Schicht aufgebracht wird und auf deren anderer Oberfläche die restlichen schmelzbaren und nichtschmelzbaren Schichten in beliebiger Reihenfolge angeordnet werden; daß dann die schmelzbare Folie und die schmelzbaren und nichtschmelzbaren Schichten an diskret verteilten Stellen in Richtung ihrer Wandstärke während eines vorgegebenen Zeitintervalls zusammengedrückt werden, so daß die schmelzbare Folie und die schmelzbare Schicht aufgeschmolzen werden und dabei die nichtschmelzbare Schicht von beiden Seiten durchtränken, wodurch die beiden Schichten miteinander verklebt werden, und daß danach die schmelzbare Folie unter Ausreißen der verklebten Stellen von dem gebildeten Schichtwerkstoff abgenommen oder abgezogen wird. Sehr wirksam ist ein weitergebildetes Verfahren, bei dem das Verkleben durch Druckeinwirkung bei ültraschallerhitzung durchgeführt wird.According to the invention, such a layer material is shown in easily produced by a process in which at least one fusible and at least one non-meltable layer are glued together under the action of pressure, and which is characterized in that a sheet of a fusible material is applied to a surface of a non-fusible layer and on the other surface of which the remaining fusible and non-fusible layers are arranged in any order will; that then the fusible film and the fusible and non-fusible layers to discreetly distributed points are compressed in the direction of their wall thickness during a specified time interval, so that the fusible film and the fusible layer are fused and the non-fusible Soak the layer from both sides, whereby the two layers are glued together, and then the fusible film removed or peeled off from the layer material formed while tearing off the bonded areas will. A further developed method is very effective, in which the gluing by the action of pressure Ultrasonic heating is carried out.

In den vorliegenden Unterlagen wird mit dem Begriff "nichtschmelzbare Schicht" eine Schicht oder Lage aus einem Werkstoff bezeichnet,'der unter Wärmeeinwirkung nicht schmelzbar oder erweichbar ist bzw. als nicht geeignet für eine übliche Schmelzbehandlung durch Erwärmen angesehen wird. Eine solche nichtschmelzbare Schicht kann aus faserigem Gut bestehen, beispielsweise gewebte Textilien, nichtgewebte (non-woven) Textilien, Schnüre oder Litzen, Baumwollstoffe usw., oder aber auch aus geschäumten Kunststoff-Schichten und ähnlichem. Als Beispiele für das faserige Gut seien Naturfasern, glasfaserverstärkte Kunststoffasern und eine Mischung dieser beiden Faserarten genannt. Als "schmelzbare Schicht" wird jede Schicht aus irgendeinem Werkstoff, der zum Schmelzen oder Erweichen durch eine übliche Wärmebehandlung geeignet ist, bezeichnet.In this document, the term "non-fusible layer" is used to denote a layer or ply designates a material that cannot be melted or softened under the action of heat or is not suitable is considered to be a common enamel treatment by heating. Such a non-meltable layer can consist of fibrous material, for example woven textiles, non-woven (non-woven) textiles, cords or braids, cotton fabrics, etc., or also made of foamed Plastic layers and the like. As examples of that fibrous goods are natural fibers, glass fiber reinforced synthetic fibers and a mixture of these two types of fiber called. A "fusible layer" is any layer made of any material that melts or softens is suitable by a conventional heat treatment, referred to.

Eine solche Schicht kann aus faserigem Gut, beispieIs- ■ weise gewebte Fasern, nichtgewebte Fasern, Schnüre oder Litzen, Baumwollstoffe u.ä; oder auch aus geschäumten. Kunststoffen, bestehen. Als Beispiele seien thermoplastische Kunststoffasern wie etwa Nylon, Polyacryl, Polyester und Polypropylen genannt; außerdem Kunststoffasern mit einer gewissen Naturfaser-Beimischung sowie geschäumte thermoplastische Kunststoffe, Wie Polyurethan-, Vinylchlorid-Schaum usw.'Such a layer can be made of fibrous material, beispieIs- ■ wise woven fibers, nonwoven fibers, cords or Braids, cotton fabrics and the like; or from foamed. Plastics. Examples are thermoplastic synthetic fibers such as nylon, polyacrylic, polyester and Called polypropylene; also synthetic fibers with a certain admixture of natural fibers and foamed thermoplastics Plastics, such as polyurethane, vinyl chloride foam, etc. '

Die nichtschmelzbaren und die schmelzbaren Schichten können in jeder beliebigen Kombination verwendet werden. Die Vorteile der Erfindung kommen allerdings dann besonders zum Tragen, wenn zumindest eine nichtschmelzbare Schicht eine der äußeren Oberflächen des Schichtwerkstoffs bildet. Wird eine nichtschmelzbare Schicht mit A und eine schmelzbare Schicht mit B bezeichnet, so ergibt sich folgende Darstellung einiger Beispiele aus der Vielzahl möglicher Kombinationen: A-Bf A-B-A, A-Bl-B2, A-Bl-B2-A, A-B-A-B, A-B1-B2-B3, A-B-A-B-A usw. Mit Bl, B2, B3 werden unterschiedlich aufgebaute Schichten bezeichnet, wie beispielsweise ein kattunartiges Gewebe/ eine geschäumte Schicht, ein Tuchstoff usw,The non-fusible and fusible layers can be used in any combination. However, the advantages of the invention are particularly evident when at least one non-meltable layer forms one of the outer surfaces of the layer material. If a non-meltable layer is designated with A and a meltable layer with B, the following illustration of some examples from the multitude of possible combinations results: AB f ABA, A-B1-B2, A-B1-B2-A, ABAB, A-B1 -B2-B3, ABABA etc. With B1, B2, B3 differently structured layers are referred to, such as a calico-like fabric / a foamed layer, a cloth, etc.,

Folie C und die schmelzbare Schicht E aufgeweicht werden und von beiden Seiten her in die nicht schmelzbare Schicht B eindringen und diese durchtränken„ Dabei werden die schmelzbare Folie und die schmelzbare Schicht auf das engste mit der nichtschmelzbaren Schicht A verklebt oder verbunden und bilden dadurch einen Schichtwerkstoff. Zum Aufschmelzen der schmelzbaren Folie und der schmelzbaren Schicht werden bekannte Mittel, beispielsweise ultraschallwellen, Hochfrequenzheizung, Widerstandsheizung usw. je nach Bedarf verwendet. Nachdem das Verbinden· oder Verkleben beendigt ist, wird die schmelzbare Folie C von der zugeordneten nichtschmelzbaren Schicht abgenommen oder abgezogen. Da aber die aufgeschmolzenen-Stellen der Folie .eng und dauerhaft mit der nichtschmelzbaren Schicht verbunden sind, werden beim Abziehen der Folie diese (punkt- oder strichweisen) Stellen aus der Folie ausgerissen. Die Folie kann jeweils mehrfach benutzt werden, indem sie bei jedem Herstellungsvorgang ein bißchen seitlich weitergeschoben wird, so daß jeweils die nicht ausgerissenen Teile auf die zu verbindenden Stellen zu liegen kommen. Als Material für die schmelzbare Folie können unterschiedliche thermoplastische Kunststoffe oder Kunstharze verwendet werden, es empfiehlt sich aber, solche Werkstoffe zu verwenden, die mit den jeweils verwendeten nicht schmelzbaren Schichten verträglich sind.Foil C and the fusible layer E are softened and from both sides into the non-fusible layer B penetrate and soak them fusible film and the fusible layer glued as closely as possible to the non-fusible layer A or connected and thereby form a layer material. For melting the fusible film and the fusible Layer are known means, such as ultrasonic waves, high frequency heating, resistance heating, etc. each used as needed. After the joining or gluing is completed, the fusible sheet C is assigned non-fusible layer removed or peeled off. But since the melted-on areas of the film. Tight and are permanently connected to the non-meltable layer, when the film is peeled off, these (point or by stripes) torn out of the film. The foil can be used several times by using it each time Manufacturing process is pushed a bit to the side, so that each of the parts not torn out on the to be connected places come to rest. Different thermoplastic materials can be used as the material for the fusible film Plastics or synthetic resins are used, but it is advisable to use such materials which are compatible with the non-meltable layers used in each case.

Eine erfindungsgemäße Vorrichtung zum Herstellen eines Matratzenschoners wird nun anhand der Zeichnung erläutert.A device according to the invention for producing a Mattress protector will now be explained with reference to the drawing.

Aus Fig. 1 ist ein Schichtwerkstoff 1 ersichtlich, der aus einer schmelzbaren Schicht 2 aus einem Polypropylen-Kattun und aus einer nichtschmelzbaren Schicht 3 aus Zellulose-Gewebe besteht. Dieser Schichtwerkstoff 1 wird einer Ultraschalle, inrichtung zugeführt, in welcher das Verbinden oderFrom Fig. 1, a layer material 1 can be seen, which consists of a fusible layer 2 made of a polypropylene calico and consists of a non-meltable layer 3 of cellulose fabric. This layer material 1 is an ultrasound, device supplied in which the connecting or

509825/0944509825/0944

Verkleben der einzelnen Schichten erfolgt. Die in Fig. 2 schematisch dargestellte Ultraschalleinrichtung besteht aus einem Elektrodenarm 4, einer dem Elektrodenarm 4 gegenüberliegenden Gegendruckwalze 5 sowie einer in Transportrichtung vor der Gegendruckwalze 5 angeordneten Zuführwalze 7 und einer hinter der Gegendruckwalze 5 angeordneten Abzugswalze 6. Die Gegendruckwalze 5 weist mehrere radial aus ihrer Oberfläche herausragende Vorsprünge 8 auf, die mit dem Elektrodenarra 4 zusammenwirken. Der Elektrodenarm 4 wird während der Drehung der Gegendruckwalze 5 bis in die Nähe der Vorsprünge 8 herangefahren..Die VorSprünge 8 sind in geeigneter Weise über die Mantelfläche der Gegendruckwalze 5 verteilt angeordnet, beispielsweise in schraubenförmigen oder parallelen Linien. Während des Zuführens des Schichtwerkstoffs 1 zu der Ultraschalleinrichtung wird eine schmelzbare Folie 9, beispielsweise aus Polypropylen, im wesentlichen an der nichtschmelzbaren Schicht 3 anliegend, ebenfalls zugeführt, und zwar von der Zuführwalze 7 über die Ultraschalleinrichtung zu der Abzugswalze 6. Der Schichtwerkstoff 1 und die schmelzbare Folie 9 werden dabei zwischen dem Elektrodenarm 4 und dem Vorsprung 8 der Gegendruckwalze 5 zusammengedrückt und gleichzeitig der Einwirkung von Ultraschallwellen ausgesetzt. Dabei werden die schmelzbare Schicht 2 und die schmelzbare Folie 9 aufgeschmolzen oder erweicht und durchtränken von beiden Oberflächen her die nichtschmelzbare Schicht 3. An den jeweiligen Verbindungsstellen 10 werden hierbei auch die Fasern der nichtschmelzbaren Schicht flachgedrückt (vgl. Fig, 4), während die Zwischenräume zwischen den einzelnen Fasern durch die Ultraschallschwingungen geöffnet werden, wodurch die schmelzbare Folie und die schmelzbare Schicht 2 miteinander verschmolzen werden können (vgl. Fig. 3). Bei der weiteren Drehung' der Gegendruckwalze 5 wird die Folie 9 von dem SchichtwerkstoffThe individual layers are glued together. The ultrasonic device shown schematically in FIG. 2 consists from one electrode arm 4, one from the electrode arm 4 opposite counterpressure roller 5 and a feed roller arranged in front of the counterpressure roller 5 in the transport direction 7 and a take-off roller 6 arranged behind the counterpressure roller 5. The counterpressure roller 5 has several radial projections 8 protruding from its surface and which interact with the electrode array 4. The electrode arm 4 is moved up to the vicinity of the projections 8 during the rotation of the counter-pressure roller 5. The projections 8 are in a suitable manner over the outer surface of the counter-pressure roller 5 arranged distributed, for example in helical or parallel lines. During the Feeding the layer material 1 to the ultrasonic device a fusible film 9, for example made of polypropylene, essentially on the non-fusible Layer 3 adjacent, also fed, from the feed roller 7 via the ultrasonic device to the take-off roller 6. The layer material 1 and the fusible film 9 are between the electrode arm 4 and the Projection 8 of the counterpressure roller 5 compressed and at the same time exposed to the action of ultrasonic waves. The fusible layer 2 and the fusible film 9 are melted or softened and impregnate the non-meltable layer 3 from both surfaces at the respective connection points 10 the fibers of the non-meltable layer are also pressed flat (see FIG. 4), while the spaces between the individual fibers can be opened by the ultrasonic vibrations, making the fusible Film and the fusible layer 2 can be fused together (see. Fig. 3). With the further rotation of the Counter-pressure roller 5 is the film 9 from the layer material

1 abgezogen, wobei aber die den aufgeschmolzenen Befestigungsstellen 10 entsprechenden Bereiche der Polie 9 von dieser ausgerissen werden. Gleichzeitig werden die aufgeschmolzenen Stellen 10 in dem Schichtwerkstoff 1 abgekühlt und verfestigt. Obwohl die danach auf die Abzugswalze 6 aufgewickelte Polie 9 stellenweise ausgerissen ist, kann sie mehrere Male verwendet werden, indem sie wie bereits erwähnt bei jedem Aufbringen auf einen neuen Schichtwerkstoff geringfügig in ihrer Lage verschoben wird.1 withdrawn, but with the melted fastening points 10 corresponding areas of the pile 9 are torn out of this. At the same time, the melted Points 10 in the layer material 1 are cooled and solidified. Although the pile 9 then wound onto the take-off roller 6 is torn out in places it can be used several times, as mentioned earlier, each time it is applied to a new one Layer material is shifted slightly in their position.

Die Schicht 2 aus Kunststoffaser-Kattun und die schmelzbare Folie 9 sind im Bereich der aufgeschmolzenen Stellen sehr eng mit der nichtschmelzbaren Schicht 3 verbunden und die entsprechenden Stellen 10 der nichtschmelzbaren Schicht 3 sind dabei beidseitig von den aufgeschmolzenen Stellen der Kunststoffaser-Kattunschicht 2 bzw. der schmelzbaren Folie 9 bedeckt, wie aus Fig. 4 ersichtlich.The layer 2 of synthetic fiber calico and the fusible Foil 9 are very closely connected to the non-meltable layer 3 in the area of the melted points and the corresponding points 10 of the non-meltable layer 3 are on both sides of the melted points of the Synthetic fiber calico layer 2 or the fusible film 9 covered, as can be seen from FIG.

Als Folge hiervon ist die schmelzbare Schicht 2 nur unter Schwierigkeiten von der nichtschmelzbaren Schicht 3 wieder zu trennen. Der Schichtwerkstoff weist eine klare Zeichnung in Form der verbundenen oder verklebten Stellen 10 auf, die ein ansprechend wirkendes Steppmuster ergeben. Durch Verwendung einer farbigen Kunststoffolie kann dem Schichtwerkstoff ein ästhetisch wirkendes Aussehen verliehen werden. In Fig. 5 ist ein Beispiel eines mit einem Punktmuster versehenen erfindungsgemäßen Schichtwerkstoffs dargestellt. Das Muster ist nach Belieben wählbar.As a result, the fusible layer 2 is only below Difficulty separating from the non-fusible layer 3 again. The layer material has a clear drawing in the form of the connected or glued points 10, which result in an appealing quilted pattern. By Use of a colored plastic film can add to the layer material an aesthetically pleasing appearance can be given. In Fig. 5, an example is one with a dot pattern provided layer material according to the invention shown. The pattern is freely selectable.

Da bei einem Schichtwerkstoff gemäß der Erfindung die nichtschmelzbare Schicht 3 mit zwei jeweils beidseitig anliegenden schmelzbaren Schichten eng verbunden ist, zeichnet sich der Schichtwerkstoff durch eine starke Haftung zwischen den einzelnen Schichten aus. AußerdemSince in a layer material according to the invention, the non-meltable layer 3 with two each on both sides adjacent fusible layers are closely connected, the layer material is characterized by strong adhesion between the individual layers. aside from that

509a25/0944509a25 / 0944

sind die nicht-gasdurchlässigen oder nicht-flüssigkeitsdichten Bereiche des Schichtwerkstoffs allein auf die verbundenen Stellen 10 beschränkt, wodurch eine ausgezeichnete Atmungsfähigkeit oder Durchlässigkeit erreicht wird. Ein v/eiterer Vorteil des erfindungsgemäßen Schichtwerkstoffs ist sein ästhetisch ansprechendes Aussehen.are the non-gas-permeable or non-liquid-tight Areas of the laminate material limited solely to the bonded points 10, thereby achieving excellent breathability or permeability will. Another advantage of the layer material according to the invention is its aesthetically pleasing appearance.

Durch das erfindungsgemäße Verfahren wird ein zusätzlicher Verfahrensschritt, das Aufbringen eines Klebstoffs auf den Schichtwerkstoff, eingespart, während andererseits ein Haftmittel nur an den jeweiligen Verbindungsstellen vorhanden ist. Da die schmelzbare Folie 9 mehrmals verwendet werden kann, ist der Haft- oder Kle.bemittelverbrauch gering.The inventive method is an additional Process step, the application of an adhesive to the layer material, saved, while on the other hand an adhesive is only present at the respective connection points. Because the fusible film 9 is used several times the consumption of adhesive or glue is low.

Nach dem erfindungsgemäßen Verfahren können auch zwei oder mehrere schmelzbare Schichten miteinander verbunden werden. Wenn die miteinander zu verbindenden schmelzbaren Schichten von unterschiedlicher Beschaffenheit sind, so ist es bekannt, daß mit den bekannten Verfahren keine starke Haftung zwischen ihnen zu erreichen ist. Demgegenüber wird mit dem erfindungsgemäßen Verfahren eine stark haftende Verbindung zwischen den einzelnen Schichten erreicht.According to the method according to the invention, two or several fusible layers are bonded together. When the fusible layers to be joined together are of different nature, it is known that there is no strong adhesion with the known methods can be achieved between them. In contrast, the method according to the invention a strongly adherent connection reached between the individual layers.
