Description

Die Erfindung betrifft eine Textilbahn, insbesondere Textilmaschinenbespannung, die in Querrichtung gesehen mehrere, sich in Längsrichtung parallel zueinander erstrekkende und nebeneinander angeordnete Teilbahnen aufweist, deren Seitenränder über Verbindungsmittel miteinander verbunden sind.The invention relates to a textile web, in particular textile machine clothing, the several seen in the transverse direction, extending in the longitudinal direction parallel to each other and has partial webs arranged side by side, whose side edges are connected to one another via connecting means are connected.

Textilbahnen der vorgenannten Art werden in erster Linie zum Transport von Papierbahnen durch eine Papiermaschine verwendet (GB-A-975 750; EP-B-0 464 258; US-A-5 360 656). Sie sind in Breitenrichtung gesehen aus Teilbahnen aufgebaut, deren Breite wesentlich geringer ist als die Endbreite der Textilbahn. Die Teilbahnen erstrecken sich im wesentlichen in Längsrichtung der Textilbahn, wenn auch in einem kleinen Winkel dazu schräg verlaufend. Die Textilbahn ist dadurch gebildet, daß ein oder mehrere Textilstreifen in Längsrichtung der Textilbahn sowie wendelförmig quer dazu fortschreitend gewickelt worden sind.Textile webs of the aforementioned type are used primarily for transporting paper webs through a paper machine used (GB-A-975 750; EP-B-0 464 258; US-A-5 360 656). Seen in the width direction, they are made up of partial webs, whose width is much smaller than the final width the textile web. The partial webs extend in essentially in the longitudinal direction of the textile web, albeit at an angle to it at a small angle. The textile web is formed by one or more textile strips in the longitudinal direction of the textile web as well as helical have been progressively wrapped across it.

Die Teilbahnen können aus Strukturfäden, beispielsweise in Form eines Gewebes, bestehen. Die Strukturfäden können jedoch auch einen Träger bilden, auf den ein Faservlies ein- oder beidseitig aufgenadelt ist, so daß die fertige Textilbahn einen Filz bildet. Solche Filze sind insbesondere für die Führung der Papierbahn in der Pressenpartie einer Papiermaschine geeignet.The partial webs can be made of structural threads, for example in the form of a fabric. The structural threads can however, also form a carrier on which a non-woven fabric is needled on one or both sides, so that the finished Textile web forms a felt. Such felts are special for guiding the paper web in the press section suitable for a paper machine.

Bei den vorbekannten Textilbahnen dieser Gattung überlappen sich die einzelnen Teilbahnen nicht nur, sondern verlaufen auch mit ihren Seitenrändern auf Stoß nebeneinander. Um in solchen Fällen eine hinreichende Querstabilität zu erhalten, werden die Seitenränder miteinander verbunden. In den oben genannten Dokumenten wird hierzu vorgeschlagen, die Seitenränder mit einer Zick-Zack-Naht zu vernähen, zu verschmelzen oder zu verschweißen, beispielsweise mit Ultraschallverschweißung. Alternativ dazu ist vorgesehen, die Seitenränder mit Nahtschlaufen zu versehen und die Verbindung mit Hilfe eines Steckdrahtes durch die Nahtschlaufen herzustellen.Overlap in the previously known textile webs of this type the individual partial webs not only run, but run also with their side edges abutting one another. To ensure adequate transverse stability in such cases to get, the side edges are connected. In the above documents it is proposed the side edges with a zigzag seam sew, fuse or weld, for example with ultrasonic welding. Alternatively it is planned to close the side edges with seam loops provided and the connection with the help of a plug wire through the seam loops.

In der EP-0 947 623 ist eine Verbindung der Teilbahnen vorgeschlagen, die aus über die Seitenränder der Teilbahnen vorstehenden und überlappend ineinandergreifenden Querfadenabschnitten und einem über diese Querfadenabschnitte gelegten und mit diesen verschweißten Verbindungsfaden besteht. Die Herstellung einer solchen Verbindung ist jedoch nicht problemlos, und es bereitet auch Schwierigkeiten, die Durchlässigkeit im Bereich der Seitenränder an die in den übrigen Bereichen der Teilbahnen anzupassen. In einer Papiermaschine ist es jedoch wichtig, daß die Durchlässigkeit der Textilbahn über die gesamte Breite gleichmäßig ist. Eine weitere Forderung besteht darin, daß die Verbindung der Teilbahnen untereinander sowohl in Quer- als auch in Längsrichtung möglichst fest ist.EP-0 947 623 describes a connection of the partial webs proposed that from over the side edges of the partial webs protruding and overlapping interlocking Cross thread sections and one over these cross thread sections laid and welded with this connecting thread consists. The establishment of such a connection is not without problems, and it also prepares Difficulty permeability in the area of the side margins to those in the other areas of the partial lanes adapt. However, in a paper machine it is important that the permeability of the textile web over the entire Width is even. Another requirement exists in that the connection of the partial webs to each other possible both in the transverse and in the longitudinal direction is firm.

Der Erfindung liegt die Aufgabe zugrunde, die Verbindung der Seitenränder der Teilbahnen bei einer Textilbahn der eingangs genannten Art so zu gestalten, daß sie einfacher herzustellen ist, eine gute Festigkeit hat und trotzdem so gestaltet werden kann, daß die Durchlässigkeit nicht wesentlich von der Durchlässigkeit in anderen Bereichen der Textilbahn abweicht.The invention has for its object the connection the side edges of the partial webs in a textile web type mentioned so that they are easier is to produce, has good strength and still can be designed so that the permeability is not essential of permeability in other areas the textile web deviates.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die benachbarten Seitenränder der Teilbahnen mäanderartigen Verlauf mit sich abwechselnden Vorsprüngen und Ausnehmungen haben und die Teilbahnen über diese Vorsprünge und Ausnehmungen miteinander verzahnt sind und daß die Verbindungsmittel die Vorsprünge untereinander verbinden, indem sie sich vorzugsweise in Längsrichtung erstrecken und möglichst unterbrechungslos ausgebildet sind.This object is achieved in that the adjacent side edges of the partial webs meandering Course with alternating protrusions and recesses have and the partial webs over these projections and recesses are interlocked and that the Connecting means connecting the projections to each other, by preferably extending in the longitudinal direction and are designed to be as uninterrupted as possible.

Grundgedanke der Erfindung ist es also, die die Teilbahnen begrenzenden Seitenränder nicht - wie im Stand der Technik - gerade auszubilden, sondern mäanderartig mit ineinandergreifenden Vorsprüngen und Ausnehmungen nach Art einer Verzahnung und dann die Verbindung der benachbarten Teilbahnen durch die Vorsprünge verbindende Verbindungsmittel zu bewirken. Die Herstellung dieser Art der Verbindung ist im Vergleich zu den vorbekannten Verbindungsarten relativ einfach und auch maschinell herzustellen. Es hat sich gezeigt, daß sich eine sowohl in Längs- als auch in Querrichtung sehr feste Verbindung herstellen läßt, ohne daß die Durchlässigkeit der Textilbahn im Seitenrandbereich wesentlich von der in anderen Bereichen abweicht.The basic idea of the invention is therefore that of the partial webs not delimiting margins - as in the prior art Technology - just training, but meandering with interlocking projections and recesses Kind of a gearing and then connecting the neighboring one Partial webs through the connecting means connecting the projections to effect. The production of this type the connection is compared to the previously known connection types relatively easy to manufacture and also by machine. It has been shown that both in Very firm connection both lengthways and crossways can be produced without the permeability of the textile web in the margin area significantly different from that in others Areas deviates.

Die Verbindungsmittel können beispielsweise als Nähnähte ausgebildet sein, die sich vorzugsweise parallel zur Längsrichtung der Teilbahnen erstrecken, wobei pro Verbindung auch mehrere parallele Nähnähte vorgesehen sein können. Anstatt oder auch in Kombination mit solchen Nähnähten können auch Klebebänder vorgesehen sein, die den Bereich der Vorsprünge und Ausnehmungen teilweise oder besser noch vollständig überdecken und sogar über diesen Bereich hinausgehen können. In Sonderheit können die Klebebänder Schmelzklebstoff enthalten oder daraus bestehen. Der Schmelzklebstoff kann nach Aufleben der Klebebänder mit Hitze und Druck aktiviert werden. Damit die Durchlässigkeit in diesem Bereich nicht wesentlich beeinträchtigt wird, sollten die Klebebänder durchlässig ausgebildet sein, also Lücken aufweisen, die ausreichend freie Querschnittsfläche gewährleisten.The connecting means can, for example, as sewing seams be formed, which are preferably parallel to Extend the longitudinal direction of the partial webs, with each connection several parallel seams can also be provided can. Instead of or in combination with such seams can also be provided tapes that the Part of the projections and recesses or better cover it completely and even over it Can go out of range. In special, the tapes Contain or consist of hot melt adhesive. The hot melt adhesive can after the tapes have been revived activated with heat and pressure. So that permeability not significantly affected in this area the tapes should be permeable be, i.e. have gaps that have sufficient free cross-sectional area guarantee.

Die Klebebänder können verschiedenartig ausgebildet sein. So können Klebefolien mit einer Klebebeschichtung verwendet werden, wobei die Klebebeschichtung aus einem geeigneten Klebstoff bestehen kann, wozu auch der schon oben erwähnte Schmelzklebstoff gehört. Um eine Durchlässigkeit sicherzustellen, sollten die Klebefolien perforiert sein. Statt dessen oder in Kombination können die Klebebänder aber auch als Faservlies ausgebildet sein, und zwar vorzugsweise mit einem Anteil an Schmelzklebstoffasern. Solche Klebebänder haben den Vorzug, daß sie so angepaßt werden können, daß sie die Durchlässigkeit in dem fraglichen Bereich nicht wesentlich beeinträchtigen und auch in ihrer Struktur derjenigen in den übrigen Bereichen entsprechen. Durch Aktivierung der Schmelzklebfasern mittels Hitze und Druck wird eine feste Verbindung der sich verzahnenden Vorsprünge hergestellt. Die Schmelzklebefasern können vollständig aus Schmelzklebstoff bestehen, wobei es dann zweckmäßig ist, wenn sie nur anteilig in dem das Klebeband bildenden Faservlies vorhanden sind. Sie können jedoch auch als Bikomponentenfasern ausgebildet sein, bei denen Schmelzklebstoff anteilig vorhanden ist.The adhesive tapes can be designed in various ways. So adhesive films with an adhesive coating can be used be, the adhesive coating from a suitable Adhesive can exist, which is why the above heard hot melt adhesive mentioned. Permeability ensure the adhesive films are perforated. Instead, or in combination, the tapes but also be formed as a nonwoven fabric, preferably with a proportion of hot melt adhesive fibers. Such Adhesive tapes have the advantage that they are so adapted that the permeability in the questionable Do not significantly affect the area and also in their structure corresponds to that in the other areas. By activating the hot melt adhesive fibers using Heat and pressure become a firm bond between the gear teeth Protrusions made. The hot melt adhesive fibers can consist entirely of hot melt adhesive, whereby it is then expedient if it is only partially in the Adhesive tape-forming nonwoven are present. You can but also be designed as bicomponent fibers, at which there is a proportion of hot melt adhesive.

was die mäanderartige Gestaltung der Seitenränder angeht, kommen verschiedenartige Verläufe in Frage, beispielsweise wellenartige oder zick-zack-artige Verläufe. Die Vorsprünge können jedoch auch Trapez- oder Rechteckform haben. Auch andere Verläufe der Seitenränder sind möglich.as far as the meandering design of the side edges is concerned, different types of courses are possible, for example wave-like or zigzag-like gradients. The tabs can also have a trapezoidal or rectangular shape. Other runs of the side edges are also possible.

Die Teilbahnen können in an sich bekannter Weise einen Träger aufweisen oder sogar daraus bestehen, wobei der Träger die auf die Textilbahn einwirkenden Längs- und Querkräfte aufnimmt. Sofern die Textilbahn als Filz ausgebildet sein soll, beispielsweise als ein für die Pressenpartie einer Papiermaschine bestimmter Pressfilz, können die Träger mit Faservliesen vernadelt sein, so daß sich auf beiden Seiten eine filzartige Oberfläche bildet. The partial webs can be in a manner known per se Have or even consist of carriers, the Carrier the longitudinal and Absorbs lateral forces. If the textile web is formed as a felt should be, for example, as one for the press section a paper machine of certain press felt the carrier must be needled with non-woven fabrics, so that a felt-like surface forms on both sides.

Als Träger kommen insbesondere Gewebe, Gewirke oder auch verfestigte Faservliese in Frage, wobei die Gewebe, Gewirke oder Faservliese auch mehrlagig vorliegen und zudem miteinander kombiniert werden können.Weaves, knitted fabrics or in particular come as supports consolidated nonwovens in question, taking the woven, knitted or non-woven fabrics are also available in multiple layers and also can be combined with each other.

Es können jedoch auch Kunststoffnetzwerke - ein- oder mehrlagig sowie allein oder in Kombination mit den vorgenannten Trägerarten - vorgesehen sein, wie sie beispielsweise in den EP-B-0 285 376, EP-A-0 307 182, WO 91/02642 oder WO 92/17643 beschrieben sind. Diese Kunststoffnetzwerke haben den Vorzug, daß sie an den Seitenrändern nicht ausfransen oder ausriffeln und deshalb den über die Vorsprünge gehenden Verbindungsmittel festen Halt bieten. Dabei ist es unerheblich, ob die einzelnen Stege der Kunststoffnetzwerke sich in Längs- oder Querrichtung erstrecken oder diagonal verlaufen. Die Herstellung der Kunststoffnetzwerke kann in der Art geschehen, wie in den oben genannten Dokumenten beschrieben. Eine besonders wirtschaftliche Art der Herstellung solcher Kunststoffnetzwerke besteht in der Anwendung der Extrudiertechnik, wie sie sich beispielsweise aus der US-A-4 123 491, US-A-3 917 889 und US-A-3 767 353 ergibt.However, plastic networks - one or multilayered as well as alone or in combination with the aforementioned Carrier types - be provided, such as in EP-B-0 285 376, EP-A-0 307 182, WO 91/02642 or WO 92/17643. These plastic networks have the advantage that they are on the side edges do not fray or flare and therefore the over the Provide protruding fasteners. It is irrelevant whether the individual webs Plastic networks extend in the longitudinal or transverse direction or run diagonally. The manufacture of the Plastic networks can be done in the way that in the described above documents. A special one economical way of producing such plastic networks consists in the use of extrusion technology, as for example from US-A-4 123 491, US-A-3 917 889 and US-A-3 767 353.

Die Breite des aus Vorsprüngen und Ausnehmungen bestehenden Bereichs kann entsprechend den jeweiligen Festigkeitsanforderungen gewählt werden. Zweckmäßig ist ein Bereich bis zu 50 cm Breite, wobei Bereiche in der Größenordnung von 10 bis 20 cm besonders geeignet sind. The width of the protrusions and recesses Range can be according to the respective strength requirements to get voted. An area is appropriate up to 50 cm wide, with areas of the order of magnitude from 10 to 20 cm are particularly suitable.

Die in Figur 1 dargestellte Vorrichtung 1 weist zwei beabstandete Walzen 2, 3 auf, die jeweils gleichsinnig angetrieben sind. Von einer Vorratsrolle 4 wird ein Textilstreifen 5 abgezogen. Die Vorratsrolle 4 ist leicht schräg gestellt und wird beim Abzug in Richtung des Pfeils A bewegt, also in Querrichtung. Hierdurch wickelt sich der Textilstreifen wendelförmig auf die beiden Walzen 2, 3 auf, bis eine gewünschte Breite erreicht ist. Dabei ist der Vorschub in Richtung des Pfeils A so bemessen, daß sich Teilbahnen - beispielhaft mit 6 bezeichnet - bilden, die nebeneinander liegen, so daß ihre Seitenränder auf Stoß aneinander liegen.The device 1 shown in Figure 1 has two spaced Rolls 2, 3, each driven in the same direction are. From a supply roll 4 is a textile strip 5 subtracted. The supply roll 4 is light slanted and is pulled towards the Arrow A moves, i.e. in the transverse direction. This wraps the textile strip spirally on the two Roll up 2, 3 until a desired width is reached. The feed in the direction of arrow A is like this dimension that partial webs - exemplarily designated 6 - Form that lie side by side, so that their Side edges abut each other.

Das wendelförmige Aufwickeln des Textilstreifens 5 kann auch mehrlagig geschehen, indem die Vorratsrolle 4 nach Erreichen der Endbreite wieder zurückbewegt wird, wobei der Ablaufwinkel entsprechend angepaßt wird. Im einzelnen ist dies der EP-B-0 464 258 und US-A-5 360 656 zu entnehmen. Es können aber auch zwei Schlaufen mit positivem und negativem Steigungswinkel übereinander plaziert werden.The helical winding of the textile strip 5 can also happen in multiple layers by the supply roll 4 after Reaching the end width is moved back, whereby the drain angle is adjusted accordingly. In detail this can be found in EP-B-0 464 258 and US-A-5 360 656. However, two loops with positive and negative pitch angle can be placed one above the other.
