Description

Im älteren Patent 1 903 667 ist bereits der Vorschlag gemacht worden, Hochfrequenzschweißein- oder auflagen mit einem blattartig dünnen. Fasern enthaltenden gas-, dampf-, feuchtigkeits- und flüssigkeitsdurchlässigen Träger für ein aus Kunststoff bestehendes Schweißhilfsmittel zur Herstellung von Verbundstoffen aus hochfrequenzverschweißten umd zum Verbundstoff vereinigten Stoffeinzellagen dadurch herzustellen, daß das Schweißhilfmittel in Form diskreter und ihrer Lage nach geordnet auftretender Partikel auf einem Träger aus untereinander verfilzten Fasern angeordnet ist. Das Verfahren hat mannigfache Vorteile, unter denen vor allem die hohe Wirtschaftlichkeit hervorzuheben ist, die infolge der äußerst geringen, abstandsbedingten Zahl von Partikeln, bezogen auf die Flächeneinheit der Schweißein- oder auflage, ein Ausmaß erreicht, das es ermöglicht, als Schweißhilfsmittel höchstwertige und aus diesem Grunde kostspielige Kunstharze deshalb verwenden zu können, weil ein Belag aus diesen dazu führt, daß die zu erstrebende Waschbarkeit und auch Reinigungsmittelfestigkeit des als Enderzeugnis auftretenden Verbundstoffes gewährleistet bleibt, wobei die vorerwähnten Kunstharze außerdem: schweißtechnisehen Erfordernissen bestens entsprechen, indem mit ihrer Hilfe erzeugte Nähte einerseits eine ausreichend hohe Verbindungsfestigkeit, andererseits eine eine Versprödung des Verbundstoffes vermeidende Schmiegsamkeit besitzen, die zur Einstellung und Erhaltung des &5 vom fertigen Verbundstoff verlangten, textlien Griffes führt.The earlier patent 1 903 667 already contains the suggestion made, high-frequency welding pads or pads with a thin sheet-like surface. Containing fibers Gas, vapor, moisture and liquid permeable carrier for a carrier made of plastic Welding aids for the production of composite materials from high-frequency welded and composite materials unified fabric single layers to produce that the welding aid in the form of discrete and their location is arranged according to the orderly occurring particles on a carrier made of interlaced fibers. That The process has many advantages, among which the high economic efficiency is to be emphasized, as a result of the extremely small, distance-related number of particles, based on the unit area of the Welding insert or pad, reached a level that makes it possible to use the highest quality welding aids For this reason, to be able to use expensive synthetic resins because a covering made of these is also used leads to the desired washability and detergent resistance of the end product Composite material remains guaranteed, the aforementioned synthetic resins also: welding technology Meet requirements in the best possible way by creating a sufficient seam with their help on the one hand high bond strength, on the other hand a flexibility that avoids embrittlement of the composite material who are responsible for setting and maintaining the & 5 from the finished composite required, textile handle leads.

Die Erfindung beruht auf der zusätzlichen Erkenntnis, daß sich, ausgehend von den vorerwähnten Vorschlägen des Vorpatentes und unter Verwirklichung der dargestellten Hauptvorteile desselben, die weitere Aufgabe lösen läßt, auf besonders wirtschaftliche Weise eTn profiliertes, atmungsfähiges, biegsames sowie geschmeidiges Polstermaterial herstellen zu können, bei dessen Erzeugung wieder die gesamten fertigungstechnischen Fortschritte auftreten, die für die textile Hochfrequenzverschweißung kennzeichnend sind und die bekanntlich darin bestehen, daß die Schweißwärmeentwicklung auf die Niederschmelzung ausschließlich der Partikel selbst beschränkt ist, so daß im Gegensatz zu den erheblichen thermischen Beanspruchungen, die bei der Heißversiegelung und/oder -verschweißung von Stofflagen entstehen und die die Verwendung gegen erhöhte Temperaturen empfindlicher Stoffe praktisch ausschließen, den Schmelz- und damit den Aufheizvorgängen nur das Schweißhilfsmittel in gezielter Weise unterworfen wird, so daß bei den guten Wärmeisolationsetgenschaften gerade textiler Stoffe diese vor un zuverlässigen Temperaturerhöhungen bewahrt bleiben. Im Rdhinen der gestellten Aufgabe ist es von gleichhoher Bedeutung, daß es, ausgehend von den älteren Vorschlägen, gelungen ist, Polsterungsvorgänge, die bisher nur von Hand durchführbar waren, dadurch zu mechanisieren und automatisieren, daß es zur Durchführung der Verbindungsvorgänge ausreicht, nach den Vorschlägen des Vorpatentes ausgerüstete Stoffe durch ein Hochfrequenzfeld durchzuführen, innerhalb dessen das dargestellte, textile Schweißverfahren selbsttätig abläuft, womit es, bei entsprechender Anordnung der zu verbindenden Stofflagen im Verhältnis zueinander, zu der Verbindung kommt, die bisher nur manuell durchführbar war.The invention is based on the additional knowledge that, based on the above-mentioned proposals of the previous patent and with implementation the main advantages shown of the same, which can solve further problem, in a particularly economical way To be able to produce eTn profiled, breathable, flexible and supple upholstery material the production of which occurs again the entire production-technological advances that occur for textile high-frequency welding are characteristic and are known to consist in the fact that the heat generated by welding is limited to the melting down exclusively of the particles themselves, so that in contrast to the considerable thermal stresses caused by the heat sealing and / or welding of Layers of fabric are created and the use of fabrics sensitive to elevated temperatures is practical exclude the melting and thus the heating processes only the welding aid in a targeted manner is subjected, so that with the good thermal insulation properties textile fabrics in particular are protected from unreliable temperature increases. In the course of the task at hand, it is equally important that, starting from the older Proposals have succeeded in upholstering processes that were previously only possible by hand mechanize and automate so that it is sufficient to carry out the joining operations after the Proposals of the previous patent to carry out finished substances through a high-frequency field, within which the illustrated, textile welding process runs automatically, with which it, with the appropriate arrangement of the layers of fabric to be connected in relation to each other, to the connection that so far only could be carried out manually.

Diese Aufgabe wird, ausgehend von einem Verfahren zum Herstellen eines Verbundstoffes, durch Verbinden von selbst schlecht oder nicht hochfrequenzverschweißbaren Einzellagen unter Verwendung mindestens einer Hochfrequenzschweißeinlage oder -auflage mit einem Träger aus Zellstoff, Schaumstoff, spunbond Stoffen oder ein- oder mehrlagigen Faserstoffvliesen für aus Kunststoffen bestehende Schweißhilfsmittel, wobei das Schweißhilfsmittel an diskreten Stellen des Trägers in Form von Partikeln auf letzterem geordnet vorgesehen ist, erfindungsgemäß dadurch gelöst, daß an den Träger des Schweißhilfsmittels elastisch nachgiebige Füllstoffe zwei- oder einseitig angelegt, mittels der Hochfrequenzschweißnähte profiliert und mit einer gas-, dampf-, feuchtigkeits- und/oder flüssigkeitsdurchlässigen Deckschicht bzw. mit Deckschichten sowie untereinander verbunden werden.Based on a method for producing a composite material, this object is achieved by joining of even poorly or not high-frequency weldable individual layers using at least a high-frequency welding insert or overlay with a carrier made of cellulose, foam, spunbond Fabrics or single or multi-layer fibrous nonwovens for welding aids made of plastics, the welding aid at discrete locations on the carrier in the form of particles on the latter is provided in an orderly manner, according to the invention achieved in that elastic on the support of the welding aid Flexible fillers applied on both sides or on one side, profiled by means of the high-frequency weld seams and with a gas, vapor, moisture and / or liquid-permeable cover layer or with cover layers as well as connected to each other.

Wenn im vorhergehenden davon gesprochen wurde, daß es gelungen ist, auf eine besonders wirtschaftliche Weise das profilierte, atmungsfähige und biegsame, schmiegsame Polstermaterial zu erzeugen, so beruht das auf der nicht ohne weiteres zu erwartenden Erkenntnis, daß es nämlich trotz sparsamsten, auf die Verwendung einzelner Kunstharzpartikel beschränkten Verbrauches an Schweißhilfsmitteln gelingt, Verbindungsnähte von einer Festigkeit zu verwirklichen, die ausreichend groß ist, um den durch die Bauschelastizität des Füllstoffes bei deren Überwindung entstehenden Kräfte zu widerstehen. Die überraschende Feststellung ist von besonderem Wert bei der Herstellung aller Textilien, bei denen Steppnähte auftreten, die bisher unter Verwendung hierauf ausgerichteter Nähmaschinen und nur mit gut eingearbeiteten Arbeitskräften exakt und mit gleicher Größe von den SteppnähtenIf it has been said in the foregoing that it has succeeded, it is a particularly economic one Way to produce the profiled, breathable and pliable, pliable upholstery material is based that on the not immediately to be expected knowledge that it is namely, despite the most economical, on the use individual synthetic resin particles limited consumption of welding aids succeeds in connecting seams to be realized by a strength that is sufficiently large to by the elasticity of the bulk of the filler to withstand forces that arise when overcoming them. The surprising finding is of particular value in the manufacture of all textiles with quilted seams that have previously occurred using specially designed sewing machines and only with well trained workers exactly and with the same size of the quilting seams

umrandeter Felder hergestellt werden konnten. Hier iührt das vorgeschlagene, neue Verfahren zu dem weiteren Vorteil, Schweißelektroden zur Anwendung bringen zu können, mit deren Hilfe es möglich ist, sogenannte Ziersteppnähte herstellen zu können, weiche an Genauigkeit und an mustergetreuer Wiederholung von Hand gefertigte Steppwaren wie Anoraks, Steppdekken. Tür- und Wandverkleidungen übertreffen, wozu der Vorteil tritt, daß die zu diesen Erzeugnissen führenden Vorgänge bis zur vollen Automatisierung mechanisiert werden können, so daß die Fertigung, wie vorher erwähnt, in besonders wirtschaftlicher Weise zu realisieren isLbordered fields could be produced. Here the proposed new method is added to the other The advantage of being able to use welding electrodes, with the help of which it is possible, so-called To be able to produce decorative quilted seams, soft in accuracy and in pattern-faithful repetition of Hand-made quilted goods such as anoraks, quilted blankets. Door and wall coverings surpass why the advantage arises that the processes leading to these products are mechanized to the point of full automation can be, so that the production, as mentioned before, to be realized in a particularly economical manner isL

Das Verfahren läßt sich in verschiedener Weise verwirklichen, beispielsweise dadurch, daß der Träger des Schweißhilfsmittels in die Mittelebene des Verbundstoffes, vorzugsweise symmetrisch zu der Anordnung der Füllstoffe, verlegt wird. Ebenso aber ist es möglich, den gleichen Träger einseitig zum Füllstoff anzubringen. Es hängt daher von der Art des jeweils auftretenden Bedürfnisfalles ab, in welcher Weise die Anpassung an diesen jeweils zu verwirklichen ist.The method can be implemented in various ways, for example in that the carrier of the Welding aid in the center plane of the composite material, preferably symmetrical to the arrangement the fillers, is laid. But it is also possible to attach the same carrier on one side to the filler. It therefore depends on the type of need that arises in which way the adjustment is to be realized on each of these.

Nach dem Dargelegten führt die Erfindung zu der Möglichkeit, ein Ausrüstmittel zum Herstellen von Verbundstoffen dahin auszubilden, daß der mit den Kunststoffpartikeln versehene Träger als Halbzeug mit dem elastisch nachgiebigen, jedoch nocht nicht profilierten Füllstoff verbunden ist. Ein so ausgebildetes Halbzeug entwickelt bei der Verarbeitung zur Fertigware, <3. h. unter dem Einfluß eines Hochfrequenzfeldes, sämtliche der Eigenschaften, die es nach der obigen Darstellung bereits latent enthält. Der mit dem Träger verbundene Füllstoff kann dann je nach Bedarf mit einer beliebigen Deckschicht längs gewünschter Konturen verschweißt und profiliert werden.In view of the foregoing, the invention leads to the possibility of a means of equipment for making composites to train that the carrier provided with the plastic particles as a semi-finished product with the elastically resilient, but not yet profiled filler is connected. A semi-finished product designed in this way developed during processing into finished goods, <3. H. under the influence of a high frequency field, all of the properties which it already contains latently according to the description above. The one associated with the carrier Filler material can then be welded along desired contours to any cover layer as required and be profiled.

Verbundstoffe mit profilierten Füllungen und mit Lagen aus verschiedenen Werkstoffen sind an sich nicht neu. Soweit jedoch Füllungen aus synthetischen Schaumstoffen oder Watte profiliert wurden, handelt es sich um thermische Schweißnähte, die den obenerwähnten Nachteil der Beschränkung auf temperaturfes'os Material haben. Auch Preßverschweißungen im Ho hfrequenzfeld schlecht verschweißbarer Kunststoffe, wie sie in Form beispielsweise von I\>lyurethan- oder Polystyrolschaum auftreten, mit artfremden Stoffen wie Hartpappe, Karton Papier oder artfremder Stoffe untereinander sind als Stand der Technik bekannt, aber dann wurden Schweißhilfsmittel aus einem mit PVC — Lösungen getränkten oder beschichteten Papier, insbesondere Seidenpapier, benutzt. Da ds Papier den Schweißvorgang übersteht, verbleibt es demgemäß auch bei der Erhaltung der für Papier kennzeichnenden Eigenschaft der Undurchlässigkeit für Gase, Dämpfe, Feuchtigkeit und Flüssigkeiten (Nässe), so daß auch dieser bekannte Vorschlag nicht zur Erfindung hin zu führen vermochte. Sodann kennt man Vorrichtungen zum Herstellen von Steppfolien mit einer mit hochfrequentem Wechselstrom gespeisten Schweißmatrize, die zwei Hüllfolien aus schweißbarem Kunststoffmaterial, etwa aus PVC, aufweist, zwischen denen eine aus einem Vlies bestehende Einlage liegt, um zu einer Einheit verbunden zu werden, wobei die Einlage mit vorstehenden Stegen versehen ist; eine Gegenelektrode bildet eine flächige Stützauflage für die während des Schweißvorganges zwischen Matrize und Gegenelektrode eingeklemmten Folien, und es sind Vorschubeinrichtungen zur Zufuhr der Folienbahnen und der Zwischenlage zum und zur Ableitung der Steppfolie aus dem Schweißbereich vorgesehen. Da aber geschlossen ausgebildete Folien sowohl jegliche Per- als auch Transpiration ausschließen, sind mit einer derartigen Vorrichtung gefertigte Erzeugnisse für die der Erfindung gesetzten Zwecke unbrauchbar.Composite materials with profiled fillings and with layers of different materials are not per se New. However, insofar as fillings made of synthetic foam or wadding are profiled, this is the case These are thermal welds that have the aforementioned disadvantage of being limited to temperature-resistant Have material. Even pressure welds in the high frequency field of plastics that are difficult to weld, as they occur in the form of polyurethane or polystyrene foam, for example, with foreign substances such as hard cardboard, cardboard, paper or different materials are known to be state of the art, But then welding auxiliaries were made from one impregnated or coated with PVC solutions Paper, especially tissue paper, is used. Since the paper survives the welding process, it remains accordingly also with the preservation of the characteristic of paper of impermeability for Gases, vapors, moisture and liquids (moisture), so that this well-known proposal is not part of the invention either was able to lead. Then one knows devices for the production of quilted films with a with high-frequency alternating current fed welding die, the two enveloping foils made of weldable Plastic material, for example made of PVC, between which there is an insert made of a fleece, to be connected to form a unit, the insert being provided with protruding webs; a counter electrode forms a flat support for the during the welding process between the die and Opposite electrode clamped foils, and there are feed devices for feeding the foil webs and the intermediate layer is provided for and for deriving the quilted film from the welding area. There but closed foils exclude both any per- and transpiration, are with a Such a device manufactured products for the purposes set of the invention useless.

Die Zeichnung gibt in stark schematisierter Darstellung eine Reihe von Ausführungsbei&pielen der Erfindung wieder.The drawing shows a series of embodiments of the invention in a highly schematic representation again.

F i g. 1 zeigt die Ausbildung eines bahnförmigen, mittels des vorgeschlagenen Verfahrens auf besonders wirtschaftliche Weise hergestellten, profilierten, atmungsfähigen, bieg- und schmiegsamen Polstermaiteriales, bei dem eine Trägerbahn für ein Schweißhilfsrnittel etwa in der Mittelebene der Bahn aus dem Polstermaterial auftritt, währendF i g. 1 shows the formation of a web-like, means the proposed method in a particularly economical way produced, profiled, breathable, flexible and pliable upholstery materials, in which a carrier web for a welding aid approximately in the central plane of the web made of the padding material occurs while

F i g. 2 ein weiteres Ausführungsbeispiel veranschaulicht, bei dem die Trägerbahn für das Schweißhilfsmitiel an einer Außenfläche der Bahn aus dem erfindungsgemäß ausgebildeten Polstermaterial vorgesehen ist, wobei beide Figuren in einem stark vergrößerten Maßstab und schematisch gehalten sind.F i g. 2 illustrates a further embodiment in which the carrier web for the welding accessory is provided on an outer surface of the web made of the cushioning material designed according to the invention, wherein both figures are kept on a greatly enlarged scale and schematically.

In F i g. 1 sind 1 und 2 bahnförmiges Polstermaterial in üblicher Weise oben und unten abkleidende Bezugstoffe, zwischen denen Füllstoffe 3, 4 liegen, die als Vlies ausgebildet sind. Als Werkstoffe für derartige Füllungen kommen aber alle Faserstoffe in Betracht, deren Eigenschaften sie befähigen, die Wirkung von Füllstoffen zu übernehmen. Zu nennen sind insbesondere die natürlichen und die Chemiefasern, außer den natürlichen Faserstoffen die Pflanzen- und tierischen Faserstoffe, unter den Chemiefasern diejenigen aus natürlichen und synthetischen Rohstoffen.In Fig. 1, 1 and 2 are sheet-like upholstery material that covers the top and bottom in the usual way, between which fillers 3, 4 lie, which are designed as a fleece. As materials for such fillings but all fibrous materials come into consideration, the properties of which enable them to have the effect of fillers to take over. Particular mention should be made of natural and man-made fibers, apart from natural Fibers the plant and animal fibers, among the man-made fibers those made from natural and synthetic raw materials.

Vorhanden ist schließlich eine das Schweißhilfsmittel tragende, mittlere Trägerbahn 5.Finally, there is a middle carrier web 5 carrying the welding aid.

Als Schweißvermittler sind aus Polyamiden bestehende Kunstharzpartikel 51 schematisch angedeutet.Synthetic resin particles 51 made of polyamides are indicated schematically as welding mediators.

Der Trägermittelbahn 5 ist beim Ausführungsbeispiel nach F i g. 1 in gedachte Abschnitte 52, 53 und 54 aufgeteilt zur Darstellung gebracht worden, um anzudeuten, daß beispielsweise gemäß der Wiedergabe des Abschnittes 52 als Trägerbahn eine aus einem Schaumstoff bestehende Stofflage vorgesehen sein kann, wobei etwa an einen Polyurethanschaumstoff zu denken ist.
Bei dem weiteren Teilabschnitt 53 der Polstermaterialbahn ist davon ausgegangen worden, daß ein ein- oder mehrlagiges Faserstoffvlies zur Bildung der Partikelträgerbahn 5 herangezogen worden ist, wobei die in das Vlies eingelagerten Kunstharzpartikel mit 55 bezeichnet sind.
The carrier middle web 5 is in the embodiment according to FIG. 1 has been divided into imaginary sections 52, 53 and 54 to indicate that, for example, according to the representation of section 52, a layer of foam made of a foam material can be provided as the carrier web, such as a polyurethane foam.
In the case of the further section 53 of the padding material web, it was assumed that a single or multi-layer fibrous web was used to form the particle carrier web 5, the synthetic resin particles embedded in the web being denoted by 55.

Schließlich soll der Abschnitt 54 der Trägerbahn andeuten, daß als Träger aus modifizierten Polyamiden bestehende Kunsharzpartikel 56 auch Zellstoff in Betracht kommt, in den die Partikel eingelagert sind.
Eine weitere, nicht dargestellte Möglichkeit würde in der Verwendung von spun - bond Stoffen bestehen, wie überhaupt zur Ausbildung der Trägerbahn jeder Werkstoff in Betracht kommt, der in der Lage ist, durch Anoder Einlagerungen angeordmetes, geeignet aufzunehmen und in ihrer Lage zu erhalten.
Finally, section 54 of the carrier web is intended to indicate that synthetic resin particles 56 consisting of modified polyamides can also be used as carrier, in which the particles are embedded.
Another possibility, not shown, would be the use of spunbond materials, as any material can be considered for the formation of the carrier web which is capable of being arranged, suitably received and kept in its position by means of accumulations.

Eine räumliche Profilierung ist dadurch entstanden, daß im Bereiche der Nähte 71, 72 usw. an die Polstermaterialbahn Hochfrequenzelektroden zur Anlage gebracht und dem Einfluß eines Hochfrenuenzfeldes ausgesetzt worden waren. Die unter dem Einfluß des Hochfrequenzfeldes eintretende Veränderung der Partikelträgerbahn 5 ist zeichnerisch nicht veranschaulicht worden, um die Darstellung der in den Abschnitten 52, 53 und 54 im nocht nicht niedergeschmolzenen ZustandA spatial profile is created by the fact that in the area of the seams 71, 72, etc., the padding material web Brought high-frequency electrodes to the plant and exposed to the influence of a high-frequency field had been. The change in the particle carrier path that occurs under the influence of the high-frequency field 5 is not graphically illustrated in order to show the representation of the sections 52, 53 and 54 not yet melted down

wiedergegebenen Partikel nicht zu stören. Aber selbstverständlich erstrecken sich die durch die Hochfrequenznähte 71, 72 usw. entstehenden, räumlichen Profilierungen in die das Schweißhilfsmittel tragende, mittlere Bahn 5 hinein, so daß die Kunstharzpartikel 51, 55 und 56 aufgrund des HF-Verschweißungsvorganges das Lagenbündel I, 3, 5, 4, 2 zu dem herzustellenden Verbundstoff auf Dauer verbinden und vereinigen.not to disturb the reproduced particles. But of course they extend through the high frequency seams 71, 72 etc. resulting, spatial profiles in the middle bearing the welding aid Web 5 in, so that the synthetic resin particles 51, 55 and 56 due to the HF welding process Layer bundles I, 3, 5, 4, 2 for the composite to be produced connect and unite in the long term.

Ihrerseits nicht dargestellte, der Erzeugung des HF-Feldes dienende FJektroden können hierbei so ausgebildet sein, daß Stepp- oder Ziersteppnähte nachgebildet wurden, die bisher von Hand hergestellt wurden. Die Stepp- oder Ziersteppnähte umranden in an sich bekannter Weise bei 81,82,83 usw. angedeutete Kissen, die infolge der durch die Schweißnähte im zusammengedrückten Zustand ge- und erhaltenen Füllstoffe 3 und 4 die erstrebte hohe Bauschelastizität aufweisen und daher in bei Steppware üblicher Weise zurückfedern, sobald die Kissen unter Überwindung der für die Bauschelastizität ursächlichen Kräfte beim praktischen Gebrauch komprimiert werden.Electrodes which are not shown and are used to generate the RF field can be designed in this way be that quilted or decorative quilted seams were reproduced that were previously made by hand. The quilted or decorative quilted seams border in a manner known per se at 81,82,83 etc. indicated cushions, as a result of the filled and obtained by the welds in the compressed state fillers 3 and 4 have the desired high structural elasticity and therefore spring back in the manner customary with quilted goods, as soon as the cushions overcome the forces that are causal for the elasticity of the lump in practical Use to be compressed.

F i g. 1 läßt weiter erkennen, daß das HF-FeId und unter seinem Einfluß stehende Elektroden auch dazu benutzt werden können, um die Polstermaterialbahn 6 an einem Ende oder an beiden Enden bei 9 unter Einfluß der Füllungen 3 und 4 sowie der Partikelträgerbahn 5 unter Bildung einer einheitlichen Naht zu verschließen. Jedoch könnten an der Stelle 9 auch Einfaßbänder oder andere bekannte Maßnahmen verwirklicht sein, um einem Abschnitt der Bahn 6, der beispielsweise der Bildung einer Steppdecke dient, ein geschmacklich befriedigendes Aussehen zu geben.F i g. 1 further shows that the HF field and electrodes under its influence are also included can be used to influence the padding material web 6 at one end or at both ends at 9 to close the fillings 3 and 4 and the particle carrier web 5 to form a uniform seam. However, edging tapes or other known measures could also be implemented at the point 9 be to a portion of the web 6, which is used, for example, to form a quilt, a taste to give a satisfactory appearance.

Bei dem Ausführungsbeispiel nach F i g. 2 begrenzt die Partikelträgerbahn 10 die gesamte Polstermaterialbahn β im wesentlichen einseitig, und zwar auf der unteren Seite. Daher ist die Polstermaterialbahn 6 auf der anderen Seite, nämlich oben, mittels eines dort vorgesehenen, oberen Bezugstoffes 1 abgedeckt. Zur Part' kelträgerbahn 10 hin schließen sich an den Oberstoff 1 eine aus einem Schaumstoff bestehende, weitere Stoffbahn 11 und eine Bahn 12 aus Füllstoffen an, die aus Faservliesen bestehen. Die Partikel trägerbahn 10 istIn the embodiment according to FIG. 2, the particle carrier web 10 delimits the entire cushioning material web β essentially unilateral, namely on the lower side. Therefore, the padding material web 6 is on the other side, namely above, covered by means of an upper cover fabric 1 provided there. To the part ' kelträgerbahn 10 to close to the outer fabric 1 consisting of a foam, further fabric web 11 and a web 12 of fillers, which consist of nonwovens. The particle carrier web 10 is

ίο wieder, in gedachte Längenabschnitte aufgeteilt, dahin dargestellt, daß der Trägerbahnabschnitt 13 aus einem Schaumstoff, der Trägerbahnabschnitt 14 aus einem Faservliesstoff und der Trägerbahnabschnitt 15 aus einem Zellstoff bestehen. Daß auch andere Möglichkeiten verwirklichbar sind, beispielsweise aus einem spunbond Stoff bestehende Abschnitte, wurde bereits in Verbindung mit F i g. 1 erläutert. Gleiche Gegebenheiten treten beim Ausführungsbeispiel nach F i g. 2 auf, da sie unabhängig davon zu verwirklichen sind, an weleher Stelle der Polstermaterialbahn die Trägerbahn jeweils liegt. Was für Längenabschnitte ausgeführt worden ist, gilt sinngemäß auch in der Richtung senkrecht hierzu, so daß Lagen aus den verschiedensten Werkstoffen in ihrer Gesamtheit zur Ausbildung der Polstermaterialbahn zu dienen vermögen. Wie aber auch in F i g. 2 die Partikelträgerbahn 10 ausgebildet ist, stets sind Kunstharzpartikel 16 an sie an- oder eingelagert, so daß in bezug auf die in F i g. 2 nicht mehr zeichnerisch veranschaulichte Profilierung dieselben Voraus-Setzungen herrschen, unter denen gemäß der Darstellung der F i g. 1 die Polstermaterialbahn als profilierter Körper auftritt.ίο again, divided into imaginary length sections, there shown that the carrier web portion 13 made of a foam, the carrier web portion 14 from a Nonwoven fabric and the carrier web section 15 consist of a cellulose. That also other possibilities feasible, for example, sections consisting of a spunbond material, was already in Relation to F i g. 1 explained. The same conditions occur in the exemplary embodiment according to FIG. 2 on, because they can be realized regardless of whichever way they are Place the padding material web the carrier web is in each case. What lengths have been carried out is, applies mutatis mutandis in the direction perpendicular to this, so that layers of the most varied of materials are able to serve in their entirety to form the padding material web. But as in F i g. 2 the particle carrier web 10 is formed, synthetic resin particles 16 are always attached to or embedded in it, so that with respect to the in F i g. 2 profiling, which is no longer graphically illustrated, has the same requirements prevail, among which, according to the illustration of FIG. 1 the upholstery material web as profiled Body occurs.
