Maschine zur kontinuierlichen Herstellung von mehrlagigemMachine for the continuous production of multilayer

Verbund-PolstermaterialComposite upholstery material

Die Erfindung "betrifft eine Maschine zur kontinuierlichen Herstellung von mehrlagigem Verbund-Polstermaterial und insbesondere zur Herstellung von mehrlagigem Verbundmaterial im " Steppwarenbereich.The invention "relates to a machine for continuous production of multi-layer composite upholstery material and in particular for the production of multi-layer composite material in the " Quilted area.

Es ist bereits bei der Herstellung von Polstermatratzen bekannt, mehrlagige Verbund-Materialbahnen zu verwenden, die eine Ober- und Unterschicht aufweisen, die die Matratzenfedern umfaßt und die äußere Umhüllung der Matratzenfedern unterliegt, um einen solchen Gegenstand möglichst bequem zu gestalten. Derartige Verbund-Materiallagen weisen vorzugsweise eine Materiallage aus schwammigem oder geschäumtem Material auf, das dauerhaft auf einer oder auf beiden Seiten mit einem Vlies oder einem Pilz aus Textilfasern verbunden ist, wobei die Verbindung entweder durch eine Beleimung oder durch ein Nähen mit Spezialnadeln, insbesondere ein Steppen, geschieht, wobei letzteres die sicherere Methode der Verbindung eines Faservlieses mit dem Schaummaterial, wie beispielsweise Polyurethan, ist,It is already known in the manufacture of upholstered mattresses to use multilayer composite material webs that have an upper and lower layer which surrounds the mattress springs and is subject to the outer covering of the mattress springs, to make such an item as comfortable as possible. Such composite material layers preferably have a material layer made of spongy or foamed material that is permanent on one or both sides with a fleece or a mushroom made of textile fibers is connected, the connection either by gluing or by sewing with Special needles, especially quilting, happens, the latter being the case the safer method of joining a non-woven fabric to the foam material, such as polyurethane, is

109887/0246109887/0246

da die Verleimung nicht verhindern kann, daß sich, die am weitesten von der Polyurethan-Materiallage entfernt liegenden Textilfasern lösen können.since the gluing cannot prevent the furthest can loosen textile fibers lying away from the polyurethane material layer.

Bei den "bekannten Ausführungsformen einer solchen Vernähung oder Versteppung ist jedoch nicht gewährleistet, daß die beiden Materiallagen an ihren Kanten so fest miteinander verbunden sind, daß ein befriedigender Widerstand gegen die bei der Benutzung sowie auch bei der Verarbeitung eines derartigen Verbundmate rial es zu Polstermatratzen auftretenden Kräfte gewährleistet ist.In the "known embodiments of such a sewing or quilting, however, it is not guaranteed that the two layers of material are so firmly connected to one another at their edges are that a satisfactory resistance to the use as well as the processing of such a composite material rial it ensures forces occurring to upholstered mattresses is.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Maschine der eingangs genannten Art zu schaffen, die diesen Nachteil beseitigt. Die erfindungsgemäße Lösung besteht im wesentlichen darin, daß die Maschine Nadelköpfe aufweist, die derart angeordnet und mit !Tadeln besetzt sind, daß an den Seitenkanten der Verbund-Materialbahn sowie an vorbestimmten Querstreifen über die Materialbahn eine höhere Nadel stichdichte als in den übrigen Bereichen erzeugt wird. Hierdurch ergibt sich die gewünschte Verstärkung und besondere Widerstandskraft dieser besonders stark beanspruchten Bereiche der Verbund-Materialbahn. The present invention is therefore based on the object of creating a machine of the type mentioned at the outset which eliminates this disadvantage. The solution according to the invention consists essentially in the fact that the machine has needle heads, which are arranged and filled with reproaches that on the side edges of the composite material web as well as on predetermined Cross stripes across the material web have a higher needle stitch density than in the other areas. This results in the desired reinforcement and special resistance of these particularly heavily used areas of the composite material web.

Wie aus Fig. 1 ersichtlich, weist die Maschine eine Speicherrolle 1 für eine Materialbahn aus porösem, insbesondere geschäumtem Material 3 auf, die in den Lagern 2 drehbar gelagert ist. Die Materialbahn 3 wird mittels Hollen 4 oder einer entsprechenden Zuführeinrichtung zu dem Zuführsystem für das textile Faservlies, vorzugsweise aus Baumwolle bestehend, gefördert. Die Einbringung der Textilfasern geschieht über die Vorrichtung 5> deren Einlaß mit Mitteln zum Entfernen von Fremdstoffen in den Textilfasern versehen ist. In der Vorrichtung 5 wird das textile Faservlies 6 zusammengesetzt, das dann über einen Endlosförderer 7 zu Preßrollen 8 geleitet wird, von ^ denen das fest zusammenhängende Faservlies gebildet wird.As can be seen from Fig. 1, the machine has a storage roll 1 for a material web made of porous, in particular foamed material 3, which is rotatably mounted in the bearings 2 is. The material web 3 is by means of a Hollen 4 or a corresponding Feed device to the feed system for the textile fiber fleece, preferably consisting of cotton, promoted. The introduction of the textile fibers takes place via the device 5> the inlet of which is provided with means for removing foreign matter in the textile fibers. In the device 5, the textile fiber fleece 6 is put together, which is then passed via an endless conveyor 7 to press rollers 8, from ^ which the firmly coherent fiber fleece is formed.

Nach Verlassen der Preßwalzen 8 werden die beiden Materialbahnen 3 und 6 gemäß Bezugsziffer 9 zusammengeführt, und sie durchlaufen dann gemeinsam ein Steppwerk einer Steppvorrichtung 10, das mit Nadelköpfen 11 versehen ist, die die Vliesbahn 6 mit der Materialbahn 3> die vorzugsweise aus Polyurethan besteht, versteppen.After leaving the press rollers 8, the two webs of material 3 and 6 are brought together according to reference number 9, and they then go through a quilting unit of a quilting device together 10, which is provided with needle heads 11, which the nonwoven web 6 with the material web 3> which is preferably made of polyurethane, quilting.

Der Nadelkopf 11 ist derart angeordnet und weist eine solche Nadelbesetzung auf, daß die Nadeln in den Seitenkantenbereichen der vereinigten Materialbahn eine höhere Dichte haben, so daß in diesen Seitenkanten eine höhere Nadelstichdichte erzeugt wird. Ferner ist ein Hilfsnadelkopf 12 vorgesehen, der die Verbund-Materialbahn quer vernäht bzw. versteppt, wobei diese Quersteppstreifen vorbestimmte Abstände voneinander haben und eine Nadelstichdichte aufweisen, die der hohen Nadelstichdichte an den Seitenkanten der Verbund-Materialbahn in etwa entspricht .The needle head 11 is arranged and has such a needle occupation that the needles in the side edge areas of the combined web of material have a higher density, so that a higher needle stitch density is produced in these side edges will. Furthermore, an auxiliary needle head 12 is provided which the Composite web of material sewn or quilted transversely, these quilted transverse strips having predetermined distances from one another and have a pinhole density which corresponds approximately to the high pinhole density at the side edges of the composite material web .

Die Abstände der Querstreifen mit der hohen Nadelstichdichte werden entsprechend den Längenabschnitten gewählt, in die die Verbund-Materialbahn nachfolgend zerteilt werden soll. Diese voneinander abständigen Querdurchtrennungen erfolgen in einem Querschneidwerk 13, das in der einfachsten Ausführungsform aus einem üblichen Sägenblatt besteht, das entsprechend den ge-The distances between the horizontal stripes with the high needle stitch density are selected according to the length segments into which the Composite web of material is to be subsequently divided. These mutually spaced transverse cuts are made in one Cross cutting unit 13, which in the simplest embodiment consists of a conventional saw blade, which according to the

109887/0246109887/0246

wünsctLten Längenabschnitte periodisch, zum Einsatz kommt. J?er- " ner hat die Maschine noch eine Abgabestation 14 für die versteppten Yerbund-Materialbahnabschnitte, die entsprechend den. gewünschten Längen zugeschnitten wurden, wobei diese Materialbahnabschnitte dann in der gewünschten Weise in ihren Kanten.-bereichen eine hohe Nadelstichdichte haben, während in ihrem mittleren Bereich eine geringere, gleichförmige Nadelstichdichte vorliegt.Desired length sections are used periodically. J? Er " The machine still has a delivery station 14 for the quilted ones Yerbund material web sections corresponding to the. desired lengths were cut, these material web sections then in the desired manner in their edges have a high pinhole density, while in their central area a lower, uniform pinhole density is present.

Es ist ferner darauf zu verweisen, daß die Maschine sowohl bezüglich der zu verarbeitenden Materialbahnbreiten einstellbar ist als auch· bezüglich der Lage der Nadelkopfbereiche mit hoher Nadelzahl entsprechend einer hohen Nadelstichdichte für das Verbund-Material sowie auch bezüglich der Nadelbesatzdichte und damit der Nadelstichdichte selbst. It should also be pointed out that the machine is both in terms of the width of the material web to be processed is adjustable as well as with regard to the position of the needle head areas high number of needles corresponding to a high needle stitch density for the composite material as well as with regard to the needle setting density and thus the needle stitch density itself.
