Abstract
Description
Die Erfindung betrifft eine Papiermaschinenbespannung mit einem Träger aus wenigstens zwei Trägerlagen, welche jeweils aus Längs- und Querfäden bestehen, jedoch untereinander über ihre Fläche grundsätzlich nicht mittels Fäden verbunden sind, wobei an den stirnseitigen Enden der Papiermaschinenbespannung aus Längsfäden bestehende Nahtschlaufen vorstehen, die einer Verbindung der Enden zur Naht mittels eines durch die Nahtschlaufen geschobenen Steckdrahts dienen.The invention relates to a paper machine clothing a carrier from at least two carrier layers, each of which consist of longitudinal and transverse threads, but with each other over their area basically not by means of threads are connected, being at the front ends of the paper machine clothing seam loops consisting of longitudinal threads protrude, which connect the ends to the Seam is pushed through the seam loops Serve wire.
Im Stand der Technik ist eine Gattung von Papiermaschinenbespannungen für den Einsatz in einer Papiermaschine bekannt, bei der ein Trägergewebe vorhanden ist, das aus zwei gewebten Trägerlagen besteht, wobei die Trägerlagen jedoch über ihre Fläche nicht über Fäden miteinander verbunden sind. An den stirnseitigen Enden der Papiermaschinenbespannung sind die Trägerlagen über ihre Längsfäden unter Ausbildung von Nahtschlaufen verbunden. Über diese Nahtschlaufen können die Enden dadurch gekuppelt werden, daß die Nahtschlaufen beider Enden in Überlappung gebracht und durch die Nahtschlaufen im Überlappungsbereich ein sogenannter Steckdraht geschoben wird. Solche Papiermaschinenbespannungen sind beispielsweise der WO 00/09802 und der JP 112 00 275 zu entnehmen.The state of the art is a type of paper machine clothing for use in a paper machine known in which a carrier fabric is present, which consists of there are two woven carrier layers, the carrier layers however, not connected by threads over their surface are. At the front ends of the paper machine clothing are the carrier layers over their longitudinal threads connected with formation of seam loops. About these Seam loops can be used to couple the ends that the seam loops overlapped both ends and through the seam loops in the overlap area a so-called plug wire is pushed. Such paper machine clothing are for example WO 00/09802 and JP 112 00 275.
Ein zur Herstellung derartiger Papiermaschinenbespannungen geeignetes Verfahren ist in der US 5,015,220 beschrieben. Bei diesem Verfahren wird ein einlagiges Trägergewebe rundgewebt, und zwar mit einem Umfang, der doppelt so groß ist wie die vorgesehene Länge der Papiermaschinenbespannung, und dann mit einem aufgenadelten Faservlies versehen. Dann wird das so gewonnene schlauchförmige Gebilde zusammengedrückt, so daß zwei aufeinanderliegende Lagen entstehen. Durch Ausfransen an den stirnseitigen Enden werden aus den dort vorhandenen Längsfäden Nahtschlaufen freigelegt, die zum Verbinden der Enden in Überlappung gebracht werden können.One for the production of such paper machine clothing A suitable method is described in US 5,015,220. In this procedure, a single-layer carrier fabric is used woven round, with a circumference that is double is as long as the intended length of the paper machine clothing, and then with a needled nonwoven Mistake. Then the tube-shaped thus obtained Forms compressed so that two lying on top of each other Layers arise. By fraying the front ends are made from those present there Longitudinal threads of seam loops are exposed, which are used to connect the ends can be overlapped.
Aufgrund der besonderen Trägerkonstruktion bieten solche Papiermaschinenbespannungen eine hohe Festigkeit insbesondere auch im Nahtbereich, da die Nahtschlaufen von sich endlos über die Trägerlagen erstreckenden Längsfäden gebildet werden. Außerdem zeichnet sich diese Trägerkonstruktion gegenüber doppellagigen Trägern durch geringe Kompressibilität aus mit der Folge, daß die Entwässerungseigenschaften über die Laufzeit der Papiermaschinenbespannungen weitgehend konstant bleiben. Nachteilig ist jedoch die nicht befriedigende Stabilität im Nahtbereich. Außerdem ist die Faservliesverankerung in diesem Bereich nicht optimal. Due to the special support construction, such offer Paper machine clothing in particular high strength also in the seam area because the seam loops from longitudinal threads extending endlessly over the carrier layers be formed. This support structure also stands out compared to double-layer girders due to low Compressibility with the consequence that the drainage properties over the duration of the paper machine clothing remain largely constant. The disadvantage is however, the unsatisfactory stability in the seam area. In addition, the fleece anchoring is in this area not optimal.
Der Erfindung liegt die Aufgabe zugrunde, eine Papiermaschinenbespannung der eingangs genannten Art so zu gestalten, daß die Nahtstabilität erhöht und eine verbesserte Verankerung des Faservlieses erreichbar ist.The invention has for its object a paper machine clothing of the type mentioned at the outset, that the seam stability increases and an improved Anchoring of the nonwoven fabric is achievable.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Trägerlagen über Bindequerfäden miteinander verbunden sind, deren Anordnung auf den Bereich beider Enden der Papiermaschinenbespannung benachbart zu den Nahtschlaufen beschränkt ist. Dabei können Bindequerfäden vorhanden sein, die die Fadendichte der Querfäden nicht erhöhen, also in den Trägerlagen ohnehin als Querfäden vorhanden sind, jedoch im Unterschied zu den übrigen Querfäden so geführt werden, daß sie auch in jeweils benachbarte Trägerlagen einbinden. Alternativ oder in Kombination dazu können jedoch auch Bindequerfäden vorgesehen werden, die zusätzlich zu den in den Trägerlagen verlaufenden Querfäden eingewebt sind und damit die Fadendichte in den der Nahtschlaufen benachbarten Bereichen erhöhen.This object is achieved in that the carrier layers are connected to one another via binding transverse threads are, their arrangement on the area of both ends of the Paper machine clothing adjacent to the seam loops is limited. Cross threads can be present that do not increase the thread density of the cross threads, so already present in the carrier layers as cross threads are, however, in contrast to the other transverse threads be performed that they also in adjacent carrier layers integrated. Alternatively or in combination However, transverse binding threads can also be provided in addition to the transverse threads running in the carrier layers are woven and thus the thread density in the Increase seam loops in adjacent areas.
Eine solche Papiermaschinenbespannung zeichnet sich durch hohe Stabilität im Nahtbereich aus. Dies beruht darauf, daß die Nahtschlaufen durch die Bindefäden trägerseitig geschlossen werden und ein Verschieben der Trägerlagen blockiert wird. Davon abgesehen wird die Verankerung des Faservlieses in diesem Bereich erheblich verbessert. Beides wird erreicht, ohne daß ansonsten in die Struktur des Trägers nachteilig eingegriffen wird, d.h. die Vorteile dieser Trägerkonstruktion bleiben vollständig erhalten. Such a paper machine clothing is characterized by high stability in the seam area. This is because that the seam loops on the carrier side through the binding threads be closed and a shift of the carrier layers is blocked. That being said, the anchorage of the Nonwoven fabric improved significantly in this area. Both is achieved without otherwise being in the structure of the Carrier is adversely affected, i.e. the advantages this support structure remains intact.
Die Art der Verbindung, also die Fadenführung der Bindequerfäden, kann an die jeweiligen Anforderungen in weiten Grenzen angepaßt werden. So können Bindequerfäden vorhanden sein, die abwechselnd einen Längsfaden in der einen Trägerlage und einen um einen Längsfaden versetzten Längsfaden in der benachbarten Trägerlage einbinden. Hierdurch ergibt sich eine sehr feste Verbindung der Trägerlagen. Es können jedoch auch Bindequerfäden vorhanden sein, die in den Trägerlagen über mehrere Längsfäden gehen - sei es langflottierend oder die Längsfäden einbindend -, bevor sie von einer Trägerlage zu einer benachbarten Trägerlage wechseln. Es können auch Bindequerfäden miteinander kombiniert werden, die unterschiedlich einbinden. Dabei ist es zweckmäßig, daß zwei benachbarte Bindequerfäden spiegelbildlichen Verlauf haben.The type of connection, i.e. the thread guidance of the binding cross threads, can be tailored to the respective requirements Limits are adjusted. Cross binding threads can thus be present be alternating a longitudinal thread in one Carrier layer and one offset by a longitudinal thread Tie in the longitudinal thread in the adjacent carrier layer. This results in a very firm connection of the carrier layers. However, transverse binding threads can also be present be in the carrier layers over several longitudinal threads - be it long float or tie in the longitudinal threads - before moving from one carrier layer to an adjacent one Change carrier layer. Cross thread can also be used be combined with each other, which integrate differently. It is useful that two neighboring Binding cross threads have a mirror image course.
Auch was die Anzahl der Bindequerfäden betrifft, ist eine Anpassung an die jeweiligen Anforderungen zweckmäßig und möglich. Es sollten an jedem Ende der Papiermaschinenbespannung wenigstens ein Bindequerfaden vorhanden sein, vorzugsweise zwei bis vier Bindequerfäden. Es können jedoch auch bis zu zehn Bindequerfäden sein, wenn besonders hohe Anforderungen an die Festigkeit der Nahtverbindung gestellt werden.The number of binding cross threads is also one Appropriate to the respective requirements and possible. There should be paper machine clothing at each end there is at least one binding cross thread, preferably two to four binding cross threads. However, it can can also be up to ten binding cross threads, if special high demands on the strength of the seam connection be put.
Als Material für die Bindequerfäden kommen in erster Linie
thermoplastische Polymere in Frage, beispielsweise
Polypropylen, Polyamid 4.6, Polyamid 6, Polyamid 6.6, Polyamid
6.10, Polyamid 6.12, Polyamid 11, Polyamid 12,
PET, PTT, PBT, PPS, PEK, PEEK oder Polyester. Dabei kann
entsprechend den Anforderungen an die Bindequerfäden ein
Material verwendet werden, das sich von dem Material der
übrigen Querfäden unterscheidet. Es versteht sich, daß
die Bindequerfäden als Monofile oder Multifilamente ausgebildet
sein können.Primarily come as the material for the binding cross threads
thermoplastic polymers in question, for example
Polypropylene, polyamide 4.6,
Die Anzahl der Nahtschlaufen wird entsprechend den jeweiligen Anforderungen festgelegt. Es besteht durchaus die Möglichkeit, daß alle Längsfäden Nahtschlaufen ausbilden. Eine zweckmäßige Variante besteht jedoch darin, daß sich wenigstens ein eine Nahtschlaufe ausbildender Längsfaden mit wenigstens einem Längsfaden abwechselt, der keine Nahtschlaufe ausbildet, und daß die Nahtschlaufen der Enden der Papiermaschinenbespannung in Querrichtung zueinander versetzt sind, damit die Nahtschlaufen problemlos kammartig ineinander greifen können.The number of seam loops is according to the respective Requirements. There is definitely Possibility that all longitudinal threads form seam loops. However, an expedient variant is that at least one longitudinal thread forming a seam loop alternates with at least one longitudinal thread that does not Seam loop forms, and that the seam loops of the ends the paper machine clothing in the transverse direction to each other are offset so that the seam loops are easy can interlock like a comb.

Der in Figur 1 schematisch dargestellte Naßpreßfilz 1 ist
für den Einsatz in der Pressenpartie einer Papiermaschine
bestimmt. Aus Übersichtlichkeitsgründen ist von dem Naßpreßfilz

2 einbettenden Faserlagen sind weggelassen. Der Träger
2 ist hier nur teilweise dargestellt. Er setzt sich
nach links in Form eines liegenden U - hier gestrichelt
angedeutet - fort, so daß der Träger 2 insgesamt ein liegendes
U darstellt. Die Erstreckung des U ist den jeweiligen
Einbauverhältnissen in der Papiermaschine angepaßt.The wet press felt 1 shown schematically in FIG. 1 is

Der Träger 2 besteht aus einer innenseitigen Trägerlage 3
und einer außenseitigen Trägerlage 4. Beide Trägerlagen
3, 4 sind als Gewebe ausgebildet, die in einem kontinuierlichen
Webprozeß durch Rundweben hergestellt sind. Die
Gewebe haben Querfäden - beispielhaft mit 5 bzw. 6 bezeichnet
-, die beim Webprozeß die Kettfäden gebildet haben,
sowie Längsfäden 7, 8 als Schußfäden. Die Längsfäden
7, 8 sind aufgrund ihrer Eigenschaft als Schußfäden Teile
eines einzigen durchgehenden Fadens. Die Querfäden 5, 6
binden mit den Längsfäden 7, 8 so ein, daß die beiden
Trägerlagen 3, 4 über die Fläche keine Verbindung über
Fäden miteinander haben, d.h. die Querfäden 5 binden
nicht in die Trägerlage 4 und die Querfäden 6 nicht in
die Trägerlage 3 ein und die Längsfäden 7, 8 verbleiben
über die gesamte Länge des Trägers 2 in der jeweiligen
Trägerlage 3 bzw. 4. The
An den stirnseitigen Enden 9, 10 des Trägers 2 bildet jeder
zweite Längsfaden 7, 8 Nahtschlaufen 11, 12 aus, die
über die Enden 9, 10 vorstehen. Senkrecht zur Zeichnungsebene
entstehen hierdurch eine Vielzahl von Nahtschlaufen
11, 12 (vgl. insoweit die Bezugsziffern 17 und
19 in Figur 2 der WO 00/09802 und die Bezugsziffern 20
bzw. 22 in den Figuren 2 bis 5 der US 5,015,220). Die
Längsfäden 7, 8, die jeweils zwischen zwei Nahtschlaufen
11, 12 bildenden Längsfäden 7, 8 verlaufen, werden ohne
Ausbildung von Nahtschlaufen auf kurzem Weg zurückgeführt.At the front ends 9, 10 of the
Die eine Reihe von Nahtschlaufen 11 ist mit der anderen
Reihe von Nahtschlaufen 12 - wie dargestellt - in kammartige
Überlappung gebracht worden, so daß sich senkrecht
zur Zeichnungsebene ein Durchsteckkanal 13 bildet. Mittels
Durchschieben eines Steckdrahtes 14 durch den Durchsteckkanal
13 werden die Nahtschlaufen 11, 12 und damit
die Enden 9, 10 des Trägers 2 miteinander gekuppelt, so
daß ein endloser Träger 2 und damit auch ein endloser

In Abweichung zum vorzitierten Stand der Technik sind die
jeweils ersten beiden Querfäden an den Enden 9, 10 benachbart
zu den Nahtschlaufen 11, 12 als Bindequerfäden
15, 16, 17, 18 ausgebildet. Der im Vergleich zu den Querfäden
5, 6 andersartige Verlauf ist in Figur 1 nicht zu
erkennen, ergibt sich jedoch aus dem in Figur 2 dargestellten
Querschnitt. Dort sind die Bindequerfäden 15,
16, 17, 18 verstärkt dargestellt, um ihren Verlauf gegenüber
dem Verlauf der übrigen Querfäden 5, 6 deutlich zu
machen. Während die übrigen Querfäden 5, 6 mit den Längsfäden
7, 8 in einer Leinwandbindung jeweils ausschließlich
in der Trägerlage 3 oder der Trägerlage 4 einbinden,
verlaufen die Bindequerfäden 15, 16, 17, 18 so, daß sie
abwechselnd in beide Trägerlagen 3, 4 einbinden, und zwar
jeweils um einen Längsfaden in der einen Trägerlage 3 und
- um zwei Längsfäden 7, 8 versetzt - um einen Längsfaden
8 in der anderen Trägerlage 4. Durch diesen Verlauf der
Bindequerfäden 15, 16, 17, 18 werden die Nahtschlaufen

jedoch im Unterschied zu der Version gemäß Figur
2 in wesentlich größeren Abständen zwischen den Trägerlagen
3, 4 wechseln. Dazwischen verlaufen sie über die
Längsfäden 7, 8 und binden sie nach Art einer Leinwandbindung
ein. Es versteht sich, daß hierdurch die Verbindung
