Abstract

The woven fourdrinier, for paper/cardboard web production, has at least two woven layers with the upper layer (G1) in contact with the web and the lower layer (G2) in contact with the production machine. The layers are locked together by bonding warps (sBK). The upper layer has at least 26 different warp structures with wefts in a maximum float length of three. The bonding warps provide surface warp structures with change points (A) to the other layer.

Description

Die vorliegende Erfindung betrifft ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Formiersieb, umfassend wenigstens zwei Gewebelagen mit in einer Bandlängsrichtung sich erstreckenden Kettfäden und in einer Bandquerrichtung sich erstreckenden Schussfäden, wobei eine erste der Gewebelagen eine Bahnmaterialkontaktseite bereitstellt und eine zweite der Gewebelagen eine Maschinenkontaktseite bereitstellt und die Gewebelagen durch Bindekettfäden miteinander verbunden sind, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a fabric tape for a machine for producing web material, in particular forming fabric, comprising at least two fabric layers with warp threads extending in a tape longitudinal direction and weft yarns extending in a tape transverse direction, wherein a first of the fabric layers provides a web material contact side and a second one of the fabric layers Machine contact side provides and the fabric layers are connected by binding warp threads together, according to the preamble of claim 1.

Ein derartiges Band ist aus dem Dokument EP 1 619 295 A2 bekannt.Such a tape is from the document EP 1 619 295 A2 known.

Bei Gewebebändern, wie sie beispielsweise als Formiersiebe in Maschinen zur Herstellung von Bahnmaterial, wie z.B. Papier oder Karton, eingesetzt werden, ist eine elementare Anforderung eine möglichst geringe Markierungsneigung in dem zu fertigenden Bahnmaterial. Dies bedeutet, dass die Struktur des Gewebebandes sich in das zu fertigende Bahnmaterial möglichst wenig einprägen soll, da eine derartige Einprägung der Struktur, im Allgemeinen als Markierung bezeichnet, die Qualität des gefertigten Bahnmaterials mindert.For woven belts, such as, for example, as forming fabrics in machines for producing sheet material, such as e.g. Paper or cardboard, is an elementary requirement the lowest possible tendency to mark in the web material to be produced. This means that the structure of the fabric tape should be as little as possible to impress in the web material to be produced, since such an impression of the structure, generally referred to as marking, reduces the quality of the finished web material.

Markierungen werden vor allem dann erzeugt, wenn in dem Gewebeband eine sehr regelmäßige Bindungsstruktur bzw. Gewebestruktur vorhanden ist. Es besteht daher allgemein das Bestreben, die Rapportlängen sowohl in Kettrichtung, als auch Schutzrichtung, also allgemein die Größe eines Kett/Schuss-Rapportes möglichst groß zu gestalten. Auf diese Art und Weise wird es möglich, eine größere Variationsvielfalt der gegenseitigen Bindungspunkte von Kettfäden und Schussfäden mit entsprechend größerer Unregelmäßigkeit dieser Bindepunkte zu erzielen.Markings are mainly produced when a very regular bond structure or fabric structure is present in the fabric tape. There is therefore generally a desire to make the repeat lengths both in the warp direction, as well as protective direction, so generally the size of a warp / weft repeat as large as possible. In this way, it becomes possible to have a larger variety of variation of the mutual bonding points of warp threads and weft threads with correspondingly larger ones To achieve irregularity of these binding points.

Es ist das Ziel der vorliegenden Erfindung, ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial und ein Verfahren zur Herstellung eines derartigen Gewebebandes vorzusehen, mit welchen eine verbesserte Gewebestruktur mit geringerer Markierungsneigung erzielt wird.It is the object of the present invention to provide a fabric tape for a machine for producing web material and a method for producing such a fabric tape, with which an improved fabric structure with a lower marking tendency is achieved.

Unter Markierungsneigung soll in diesem Zusammenhang bspw. eine linienförmige Markierung verstanden werden, die bspw. in Kett- oder Schussrichtung oder einer dazu diagonalen Richtung verläuft.In this context, the term "marking tendency" is to be understood as meaning, for example, a linear marking which, for example, extends in the warp or weft direction or in a direction which is diagonal thereto.

Gemäß einem ersten Aspekt der vorliegenden Erfindung wird diese Aufgabe gelöst für ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, insbesondere Formiersieb, umfassend wenigstens zwei Gewebelagen mit in einer Bandlängsrichtung sich erstreckenden Kettfäden und in einer Bandquerrichtung sich erstreckenden Schussfäden, wobei eine erste der Gewebelagen eine Bahnmaterialkontaktseite bereitstellt und eine zweite der Gewebelagen eine Maschinenkontaktseite bereitstellt und die Gewebelagen durch Bindekettfäden miteinander verbunden sind, wobei die erste Gewebelage mit wenigstens 26 verschiedenen Kettverläufen gewebt ist, wobei die Bindekettfäden nicht Struktur bildend in die erste Gewebelage eingebunden sind und an Anbindestellen über Schussfäden der ersten Gewebelage binden und die Anbindestellen innerhalb eines Kett/Schuss-Rapportes unregelmäßig verteilt sind.According to a first aspect of the present invention, this object is achieved for a fabric belt for a machine for producing web material, in particular forming fabric, comprising at least two fabric layers with warp threads extending in a belt longitudinal direction and weft yarns extending in a belt transverse direction, wherein a first of the fabric layers Web material contact side provides and a second of the fabric layers provides a machine contact side and the fabric layers are connected by binding warp threads, wherein the first fabric layer is woven with at least 26 different Kettverläufen, wherein the binder warp threads not structure forming are integrated into the first fabric layer and bind to tethers on weft threads of the first fabric layer and the tethers are distributed irregularly within a warp / weft repeat.

Erfindungsgemäß weisen die in die erste Gewebelage strukturbildend eingewebten Kettfäden und die Schußfäden der ersten Gewebelage bezüglich einander eine maximale Flottierungslänge von 3 auf und wenigstens zwei, vorzugsweise alle, der wenigstens 26 verschiedenen Kettfadenverläufe sind nicht durch verschieben eines anderen Kerifadenverlaufs in Kettrichtung gebildet.According to the invention, the warp threads woven into the first fabric layer and the weft threads of the first fabric layer have a maximum float length of 3 and at least two, preferably all, of the at least 26 different warp thread courses are not formed by shifting another kerf thread course in the warp direction.

Es sind so genannte nicht Struktur bildende Bindekettfäden vorgesehen sein, die primär nicht in die die Bahnmaterialkontaktseite bereitstellende Gewebelage eingebunden sind und nur an einigen wenigen Stellen, so genannten Anbindungsstellen, über Schussfäden der ersten Gewebelage abbinden und auf diese Art und Weise die Verbindung verschiedener Gewebelagen miteinander realisieren.There are so-called non-structure forming warp threads can be provided, which are not primarily involved in the Bahnmaterialkontaktseite providing fabric layer and set only at a few points, so-called attachment points, via weft threads of the first fabric layer and in this way the connection of different fabric layers together realize.

Durch das Bereitstellen von wenigstens 26 verschiedenen Kettverläufen, also wenigstens 26 verschiedenen Arten, wie die auch in die erste Gewebelage eingebundenen Kettfäden bezüglich der Schussfäden der ersten Gewebelagen abbinden, wird eine sehr große Rapportlänge erzeugt, die sich über mindestens 26 Kettfäden erstreckt. Dies wiederum ermöglicht es, entweder die Austauschstellen bei so genannten Struktur bildenden Bindekettfadenpaaren oder die Anbindestellen bei nicht Struktur bildenden Bindekettfäden innerhalb eines jeweiligen Kett/Schuss-Rapportes mit großer Variationsfreiheit zu positionieren, so dass das Auftreten eines regelmäßigen Musters derartiger Austauschstellen bzw. Anbindestellen vermieden werden kann und mithin diese Stellen unregelmäßig in einem jeweiligen Rapport verteilt sind.By providing at least 26 different warp courses, ie at least 26 different types, such as the warp threads also tied into the first fabric layer with respect to the weft threads of the first fabric layers, a very long repeat length is produced which extends over at least 26 warp threads. This, in turn, makes it possible to position either the exchange points in so-called structure-forming binder warp yarn pairs or the tie sites with non-structure binding warp yarns within a respective warp / weft repeat with great freedom of variation, thus avoiding the occurrence of a regular pattern of such exchange sites or tethers and thus these places are irregularly distributed in a respective rapport.

Die erste Gewebelage (G1) kann mit 32 oder mehr, 38 oder mehr oder 45 oder mehr verschiedenen Kettverläufen gewebt sein.The first fabric layer (G1) can be 32 or more, 38 or more or 45 or more different warp courses.

Vorteilhafterweise ist innerhalb eines Kett/Schuss-Rapportes bei wenigstens der Hälfte der Schussfäden wenigstens eine Austauschstelle vorhanden.Advantageously, within at least half of the weft threads at least one replacement point is present within a warp / weft repeat.

Um einerseits eine stabile Anbindung der Gewebelagen aneinander zu erreichen, andererseits aber eine möglichst unregelmäßige Verteilung der Anbindestellen von nicht Struktur bildenden Bindekettfäden zu erreichen, wird vorgeschlagen, dass jeder nicht Struktur bildende Bindekettfaden innerhalb eines Kett/Schuss-Rapportes wenigstens zwei Anbindestellen in der ersten Gewebelage aufweist und dass bei höchstens zwei, vorzugsweise keinen, nicht Struktur bildenden Bindekettfäden alle Anbindestellen bei den gleichen Schussfäden der ersten Gewebelage liegen. Dabei kann weiter vorgesehen sein, dass innerhalb eines Kett/Schuss-Rapportes maximal drei nicht Struktur bildende Bindekettfäden vorhanden sind, bei welchen alle Anbindestellen bei den selben Schussfäden der ersten Gewebelage liegen.On the one hand to achieve a stable connection of the fabric layers to each other, but on the other hand to achieve a possible irregular distribution of tethers of non-structure binding warp threads, it is proposed that each non-forming binder warp within a warp / weft repeat at least two tethers in the first fabric layer and that at most two, preferably no, non-structure binding warp threads are all tethers at the same weft threads of the first fabric layer. It can further be provided that within a warp / weft repeat maximum of three non-forming binding warp threads are present, in which all tethers are at the same weft yarns of the first fabric layer.

Auch bei den nicht Struktur bildenden Bindekettfäden kann die Unregelmäßigkeit der Verteilung der Anbindestellen innerhalb eines Kett/Schuss-Rapportes dadurch erhöht werden, dass innerhalb eines Kett/Schuss-Rapportes bei wenigstens der Hälfte der Schussfäden der ersten Gewebelage wenigstens eine Anbindestelle vorhanden ist.Even with the non-structural binding warp threads, the irregularity of the distribution of the binding sites within a warp / weft repeat can be increased by at least one tying point is present within a warp / weft repeat at least half of the weft threads of the first fabric layer.

Die andere Gewebelage kann die zweite Gewebelage sein, was im Allgemeinen bedeutet, dass ein derartiges Gewebeband dann mit zwei Gewebelagen aufgebaut ist.The other fabric layer may be the second fabric layer, which generally means that such a fabric tape is then constructed with two fabric layers.

Weiterhin kann vorgesehen sein, dass die Anzahl an nicht Struktur bildenden Bindekettfäden kleiner oder gleich der Anzahl an nicht zur Verbindung der Gewebelagen beitragenden Kettfäden in der ersten Gewebelage ist.Furthermore, it can be provided that the number of non-structural binding warp threads is less than or equal to the number of warp threads not contributing to the connection of the fabric layers in the first fabric layer.

Um insbesondere an der Bahnmaterialkontaktseite eine vergleichsweise hohe Dichte an Kettfäden und Schussfäden und eine entsprechend dichte Webstruktur zu erzeugen, wird vorgeschlagen, dass die Anzahl an Kettfäden der ersten Gewebelage größer oder gleich der Anzahl an Kettfäden der zweiten Gewebelage ist. Dazu kann weiter vorgesehen sein, dass die Anzahl an Schussfäden der ersten Gewebelage größer oder gleich der Anzahl an Schussfäden der zweiten Gewebelage ist.In order to produce a comparatively high density of warp threads and weft threads and a correspondingly dense weave structure, in particular on the web material contact side, it is proposed that the number of warp threads of the first fabric layer is greater than or equal to the number of warp threads of the second fabric layer. For this purpose, it can further be provided that the number of weft threads of the first fabric layer is greater than or equal to the number of weft threads of the second fabric layer.

Vorzugsweise weisen alle Kettfäden innerhalb eines Kettrapportes unterschiedliche Kettverläufe auf.Preferably, all the warp threads within a Kettrapportes on different warp courses.

Weiterhin trägt zu einer verminderten Markierungsneigung bei, dass bei dem erfindungsgemäßen Gewebeband wenigstens die Hälfte der zwischen den in die erste Gewebelage Struktur bildend eingewebten Kettfäden und den Schussfäden der ersten Gewebelage bezüglich einander gebildeten Flottierungen eine Flottierungslänge von weniger als 3 aufweist.Furthermore contributes to a reduced tendency to mark that in the fabric tape according to the invention at least half of the warp yarns woven into the first fabric layer structure and the weft yarns of the first fabric layer with respect to each other formed floats has a float length of less than 3.

Erfindungsgemäß wird ein sehr unregelmäßiges Bindungsmuster erhalten werden, dass wenigstens zwei, vorzugsweise alle, der wenigstens 26 verschiedenen Kettfadenverläufe nicht durch Verschieben eines anderen Kettfadenverlaufes in Kettrichtung gebildet sind.According to the invention, a very irregular bonding pattern will be obtained, that at least two, preferably all, of at least 26 different Kettfadenverläufe not formed by moving another Kettfadenverlaufes in the warp direction.

Der Einsatz von wenigstens 26 Schäften bedeutet im Allgemeinen, dass auch wenigstens 26 verschiedene Kettfadenverläufe generiert werden mit der Folge eines entsprechend langen Kettrapportes.The use of at least 26 shanks generally means that at least 26 different warp yarn courses are also generated with the consequence of a correspondingly long warp repeat.

Die Erfindung wird nachfolgend mit Bezug auf die beiliegenden Figuren detailliert beschrieben. Es zeigen:

The invention will be described in detail below with reference to the accompanying figures. Show it:

Eine Ausgestaltungsform eines erfindungsgemäß aufgebauten Gewebebandes bzw. eine Bindungsstruktur dafür ist in den Fig. 1 und 2a bis 2g gezeigt. Auch hier zeigt die Fig. 1 wieder einen Kett/Schuss-Rapport R, der sich hier über 36 Struktur bildend in die erste Gewebelage G1 eingewebte Kettfäden und über 42 Schussfäden sowohl der ersten Gewebelage G1 als auch der zweiten Gewebelage G2 erstreckt. Die Verbindung der beiden Gewebelagen G1 und G2 erfolgt hier durch Bindekettfäden BK, die im wesentlichen Bereich ihrer Erstreckung ausschließlich in die zweite Gewebelage G2 eingewebt sind, also dort über bzw. unter den Schussfäden 1 bis 42 dieser zweiten Gewebelage G2 abbinden. An so genannten Anbindestellen A' binden jedoch diese Bindekettfäden BK mit Schussfäden der ersten Gewebelage G1. Im Falle des zwischen den beiden Struktur bildenden Kettfäden 1 und 2 der ersten Gewebelage G1 angeordneten Bindekettfadens BK sind diese Anbindestellen A' jeweils an den Schussfäden 2, 20 und 35 der ersten Gewebelage G1 gebildet. D.h., dort verläuft der Bindekettfaden BK über den Schussfäden der ersten Gewebelage G1. Davor und danach wechselt er von der zweiten Gewebelage G2 in die erste Gewebelage G1 bzw. wieder in die zweite Gewebelage G2 zurück. Da diese Bindekettfäden an der Oberfläche der ersten Gewebelage G1 lediglich im Bereich der Anbindestellen A' auftauchen, ansonsten jedoch in der ersten Gewebelage G1 nicht erscheinen, werden sie auch nicht als Struktur bildend bezeichnet, da sie einen spürbaren Beitrag zur Struktur der ersten Gewebelage G1 nicht liefern.An embodiment of a fabric tape constructed according to the invention or a binding structure for this is in the Fig. 1 and 2a to 2g shown. Again, the shows Fig. 1 again a warp / weft repeat R, which here forms over 36 structure forming in the first fabric layer G1 woven warp threads and 42 weft threads both the first fabric layer G1 and the second fabric layer G2. The connection of the two fabric layers G1 and G2 takes place here by binding warp threads BK, which are woven in the substantial area of their extension exclusively in the second fabric layer G2, so there over or under the weft threads 1 to 42 of this second fabric layer G2 set. At so-called tying points A ', however, these binding warp threads BK bind with weft threads of the first fabric layer G1. In the case of the binding warp thread BK arranged between the two warp threads 1 and 2 of the first fabric layer G1, these binding sites A 'are respectively formed on the weft threads 2, 20 and 35 of the first fabric layer G1. That is, there the binder warp BK extends over the weft threads of the first fabric layer G1. Before and after that, he changes from the second fabric layer G2 back to the first fabric layer G1 or back to the second fabric layer G2. Since these binding warp threads appear on the surface of the first fabric layer G1 only in the region of the binding sites A ', but otherwise do not appear in the first fabric layer G1, they are not referred to as forming structure, as they do not make a noticeable contribution to the structure of the first fabric layer G1 deliver.

Auch bei der in den Fig. 1 und 2a bis 2g gezeigten Bindungsstruktur ist für möglichst große Unregelmäßigkeit gesorgt. Hierzu trägt zunächst wieder bei, dass die erste Gewebelage mit einer Vielzahl an verschiedenen Kettverläufen gewebt ist. Dies bezieht sich zunächst auf die Struktur bildend in der ersten Gewebelage G1 auftretenden Kettfäden Ko, die in Fig. 1 mit 1 bis 36 durchnummeriert sind. Alle Kettverläufe dieser 36 Kettfäden Ko unterscheiden sich durch jeweils verschiedene Abbindemuster mit den Schussfäden 1 bis 42 der ersten Gewebelage G1, wobei auch hier keiner der Kettverläufe allein durch Verschieben eines anderen Kettverlaufs in der Kettrichtung generierbar ist. Auch für die Bindekettfäden, die lediglich an den Anbindestellen A' in der ersten Gewebelage G1 auftauchen, sind verschiedene Kettverläufe gewählt, was unter anderem dazu führt, dass eine völlig unregelmäßige Verteilung der Anbindestellen A' erzeugt wird. Es sind also hier für einen Kett/Schuss-Rapport 18 derartige nicht Struktur bildende Bindekettfäden BK vorhanden, so dass die Gesamtzahl der Kettverläufe von Kettfäden Ko und BK, die in der ersten Gewebelage G1 auftauchen, wiederum bei 54 liegt. Dies wieder kombiniert mit den drei verschiedenen Kettverläufen für die nur in die zweite Gewebelage G2 eingewebten Kettfäden Ku führt zu einer Gesamtzahl von 57 verschiedenen Kettverläufen innerhalb eines Kett/Schuss-Rapportes. Auch ein derartiges Gewebe bzw. eine derartige Bindungsstruktur erfordert also den Einsatz einer Hochschaftmaschine mit mindestens 57 Schäften.Also in the in the Fig. 1 and 2a to 2g shown binding structure is provided for as large as possible irregularity. First of all, this contributes to the fact that the first fabric layer is woven with a multitude of different warp courses. This refers first to the structure forming in the first fabric layer G1 occurring warp threads Ko, which in Fig. 1 are numbered 1 to 36. All warp courses of these 36 warp yarns Ko differ in each case by different setting patterns with the weft threads 1 to 42 of the first fabric layer G1, whereby here too none of the warp courses solely by shifting another warp course in the warp direction can be generated. Also for the binding warp threads, which only appear at the attachment sites A 'in the first fabric layer G1, different warp courses are selected, which among other things leads to a completely irregular distribution of the attachment sites A' being produced. Thus, for such a warp / weft repeat, there are 18 such non-structure binding warp threads BK, so that the total number of warp courses of warp yarns Ko and BK which appear in the first fabric layer G1 is again 54. This, combined with the three different warp courses for the warp threads Ku woven into only the second fabric layer G2, leads to a total number of 57 different warp courses within one warp / weft repeat. Even such a fabric or such a binding structure thus requires the use of a high-shaft machine with at least 57 shanks.

Des Weiteren ist auszuführen, dass selbstverständlich bei der in den Fig. 1 und 2a bis 2g gezeigten Bindungsstruktur hinsichtlich der Flottierung der in der ersten Gewebelage G1 Struktur bildend eingesetzten Kettfäden, also der Kettfäden Ko und der damit verwebten Schussfäden 1 bis 42 der ersten Gewebelage, das Gleiche gilt, wie bei der vorangehenden Ausgestaltungsform. Auch hier sollte also die maximale Flottierungslänge die Zahl 3 nicht übersteigen. Beispielsweise ist eine derartige über 3 Schussfäden sich erstreckende Flottierung beim Kettfaden Ko 29 in der Fig. 2f erkennbar. Der Großteil der Flottierungen ist so gewählt, dass er sich über maximal zwei jeweils andere Fäden, also Kett- oder Schussfäden, erstreckt.Furthermore, it should be understood that, of course, in the in the Fig. 1 and 2a to 2g with regard to the floating structure of the warp threads used in the first fabric layer G1 structure, ie the warp yarns Ko and the weft threads 1 to 42 of the first fabric layer woven therewith, the same applies as in the preceding embodiment. Again, the maximum float length should not exceed 3. For example, such a floating over 3 wefts floats the warp Ko 29 in the Fig. 2f recognizable. The majority of the floats is chosen so that it extends over a maximum of two other threads, ie warp or weft threads.

Zu der unregelmäßigen Positionierung der Anbindestellen A' innerhalb eines jeweiligen Rapportes R ist auch hier auszuführen, dass vorzugsweise diese so gewählt sind, dass nicht bei mehr als maximal drei Bindekettfäden BK die Anbindestellen A' jeweils bei den selben Schussfäden liegen. Sofern derartige Bindekettfäden vorhanden sind, welche alle Anbindestellen A' an den selben Schussfäden haben, wie auch andere Bindekettfäden BK, sollte dafür gesorgt sein, dass diese nicht unmittelbar nebeneinander liegen, sondern durch zumindest einen anders eingebundenen Bindekettfaden getrennt sind. Auch sollte darauf geachtet werden, dass, wie dies auch in der Fig. 1 erkennbar ist, bei möglichst vielen der in einem derartigen Rapport R vorhandenen Schussfäden Anbindestellen A' vorhanden sind. Zumindest die Hälfte der Schussfäden sollte jeweils mit einem Bindekettfaden BK abbinden, um eine derartige Anbindestelle A' zu bilden.Regarding the irregular positioning of the attachment locations A 'within a respective repeat R, it should also be stated here that these are preferably selected such that the attachment locations A' do not lie with the same weft threads in each case with more than a maximum of three binding warp threads BK. If such binding warp threads are present, which have all attachment points A 'on the same weft threads, as well as other binding warp threads BK, it should be ensured that they are not directly next to each other, but instead are separated by at least one differently bound binding warp thread. Also, care should be taken that, as in the Fig. 1 It can be seen that as many as possible of the weft threads present in such a rapport R have binding sites A '. At least half of the weft yarns should each set with a binding warp BK to form such a binding point A '.

In der vorangehend beschriebenen Art und Weise kann also eine Bindungsstruktur für ein Gewebeband für eine Maschine zur Herstellung von Bahnmaterial, beispielsweise Papier oder Karton, erzeugt werden, bei der einerseits durch die Bereitstellung sehr großer Rapporte und andererseits durch eine sehr unregelmäßige Verteilung beispielsweise der Austauschstellen A oder der Anbindestellen A' innerhalb der jeweiligen Rapporte das Auftreten regelmäßiger Bindungsmuster so weit als möglich unterdrückt wird. Dazu trägt auch eine sehr kurze Flottierungslänge bei. Infolgedessen kann ein Gewebeband erhalten werden, bei dem nicht nur die Markierungsneigung reduziert ist, sondern auch eine sehr gleichmäßige über das gesamte Gewebeband verteilte Verbindung der Gewebelagen miteinander erhalten werden kann.In the manner described above, therefore, a binding structure for a fabric belt for a machine for producing web material, such as paper or cardboard, can be generated, on the one hand by providing very large reports and on the other hand by a very irregular distribution, for example, the exchange points A or the binding sites A 'within the respective rapportees the occurrence of regular bond patterns is suppressed as far as possible. This also contributes to a very short fleet length. As a result, a cloth tape can be obtained in which not only the marking tendency is reduced but also a very uniform compound of the fabric layers distributed over the entire cloth tape can be obtained with each other.

Abschließend sei noch darauf hingewiesen, dass selbstverständlich die dargestellten Beispiele mit 54 verschiedenen Kettverläufen der in der ersten, also die Bahnmaterialkontaktseite bereitstellenden Gewebelage nicht limitierend für die vorliegende Erfindung ist. Auch kleinere Anzahlen an Kettverläufen bzw. beim Webvorgang eingesetzten Schäften können genutzt werden, um vergleichsweise große Rapporte zu erzeugen. So kann selbstverständlich innerhalb eines jeweiligen Rapportes eine gewisse Anzahl der Kettverläufe sich wiederholen, so dass beispielsweise mit 26 verschiedenen Kettverläufen auch Rapporte erzeugt werden können, die sich über 40 und mehr Kettfäden bzw. Struktur bildenden Kettfadenpaaren erstrecken. Die Anzahl von 26 verschiedenen Kettverläufen hat sich als vorteilhaft erwiesen. Es ist auch denkbar, als untere Grenzanzahl 30 verschiedene Kettverläufe oder 36 verschiedene Kettverläufe einzusetzen, was zu entsprechend größeren Rapporten führt.Finally, it should be noted that, of course, the illustrated examples with 54 different Kettverläufen of in the first, so the web material contact side providing fabric layer is not limiting for the present invention. Even smaller numbers of Kettverläufen or shafts used in the weaving process can be used to produce comparatively large rapports. Thus, of course, a certain number of warp courses can be repeated within a respective repeat, so that, for example, with 26 different warp courses, it is also possible to produce repeats which extend over 40 or more warp threads or structure-forming warp thread pairs. The number of 26 different Kettverläufen has proved to be advantageous. It is also conceivable, as a lower limit number 30 different warp courses or to use 36 different warp courses, which leads to correspondingly larger reports.

Das vorangehend beschriebene erfindungsgemäß aufgebaute Gewebeband kann insbesondere auch Anwendung finden bei der Herstellung von voluminösem Papier insbesondere Tissuepapier, allgemein auch als Tissue oder Bulky-Tissue bezeichnet. In Zuordnung zu derartigem voluminösen Papier, das also ein geringeres Flächengewicht aufweist, können dann die Kett- und Schussspezifikationen ausgewählt werden, wie z.B. die im Zusammenhang miteinander stehenden Größen Dichte und Durchmesser der Kettfäden bzw. auch der Schussfäden.The above-described fabric tape constructed according to the invention can also be used in particular in the production of voluminous paper, in particular tissue paper, also commonly referred to as tissue or bulk tissue. In association with such bulky paper, that is, having a lower basis weight, then the warp and weft specifications may be selected, e.g. the related sizes of density and diameter of the warp threads and also the weft threads.
