Description

Die Erfindung betrifft einen Maschinenfilz mit wenigstens zwei Lagen von Längsfäden aufweisenden Längsfadengelegen und einer dazwischen angeordneten Einlage sowie mit die Außenseiten des Maschinenfilzes bedeckenden Faserschichten. Sie betrifft desweiteren ein Verfahren zur Herstellung eines solchen Maschinenfilzes, bei dem wenigstens zwei Längsfadengelege unter Zwischenlegung einer Einlage übereinandergelegt werden und auf den wenigstens eine Faserschicht aufgenadelt wird.The invention relates to a machine felt having at least two layers of longitudinal yarn layers having longitudinal threads and an insert arranged therebetween, as well as fiber layers covering the outer sides of the machine felt. It further relates to a method for producing such a machine felt, in which at least two Längsfadengelege superimposed with the interposition of an insert and is applied to the at least one fiber layer.

Ein Maschinenfilz der vorgenannten Art ist in der US-A-4 781 967 beschrieben. Er ist modulweise aufgebaut, wobei zwischen zwei Längsfadengelege ein Querfadengelege oder ein Gewebe als Einlage angeordnet ist. Auf den Außenseiten der und zwischen den Längsfadengelegen sind Faserschichten vorgesehen. Die einzelnen Module werden durch Vernadelung der Faserschichten miteinander verbunden.A machine felt of the aforementioned type is described in US-A-4,781,967. It is constructed module-wise, wherein a Querfadengelege or a fabric is arranged as an insert between two Längsfadengelege. On the outsides of and between the longitudinal thread located fiber layers are provided. The individual modules are connected by needling the fiber layers together.

Maschinenfilze der vorbeschriebenen Gattung werden endlos hergestellt. Abgesehen davon, daß die Länge solcher Maschinenfilze begrenzt ist, sie also nicht überall eingesetzt werden können, gestaltet sich die Montage des Filzes beispielsweise in der Pressenpartie einer Papiermaschine schwierig. Einfacher ist die Montage eines Maschinenfilzes, wenn er in endlicher Länge vorliegt und an seinen Stirnseiten Kupplungselemente aufweist, über die die Enden des Maschinenfilzes in der Maschine miteinander gekuppelt werden können (vgl. EP-A-0 261 488).Machine felts of the type described above are produced endlessly. Apart from the fact that the length of such machine felts is limited, so they can not be used everywhere, the mounting of the felt, for example, in the press section of a paper machine designed difficult. It is simpler to mount a machine felt if it is of finite length and has coupling elements on its end faces, by means of which the ends of the machine felt in the machine can be coupled together (see EP-A-0 261 488).

Der Erfindung liegt die Aufgabe zugrunde, einen Maschinenfilz der eingangs genannten Art so auszubilden, daß er in endlicher Form vorliegt und seine Stirnseiten miteinander verbindbar sind.The invention has the object of providing a machine felt of the type mentioned in such a way that it is in finite form and its front sides are connected to each other.

Diese Aufgabe wird erfindungsgemäß daduch gelöst, daß zwei Lagen Längsfadengelege gemeinsame Längsfäden aufweisen, welche über beide Seiten der Einlage gehen und die Einlage an ihren Stirnseiten unter Ausbildung von Kupplungsösen einfassen, und daß eine einzige Einlage vorhanden ist, die ein einlagiges Querfadengelege aufweist. Grundgedanke der Erfindung ist es also, die Längsfäden von zumindest zwei Lagen Längsfadengelege um die Stirnseiten der Einlage herumzuführen, so daß die beiden Lagen von denselben Längsfäden gebildet werden. Dabei bilden die Längsfäden im Bereich der Stirnseiten der Einlage Kupplungsösen aus, die zum Zwecke der Verbindung der Stirnseiten in Überlappung gebracht und in dieser Stellung über einen Steckdraht gekuppelt werden können. Bis auf den Steckdraht sind keine weiteren besonderen Kupplungselemente erforderlich. Die durch die Kupplungsnaht hervorgerufene Unstetigkeit wird hierdurch auf ein Minimum reduziert. Außerdem ergibtsich eine einfache Herstellung des Maschinenfilzes.This object is achieved according to the invention daduch that two layers Längsfadengelege have common longitudinal threads which go over both sides of the insert and border the insert at their ends to form Kupplungsösen, and that a single insert is present, which has a single-layer Querfadengelege. The basic idea of the invention is thus to guide the longitudinal threads of at least two layers of longitudinal thread lay around the end faces of the insert, so that the two layers are formed by the same longitudinal threads. In this case, the longitudinal threads form in the region of the end faces of the liner coupling eyes, which can be brought into overlap for the purpose of connection of the end faces and coupled in this position via a pintle. Except for the pintle, no further special coupling elements are required. The discontinuity caused by the coupling seam is thereby reduced to a minimum. In addition, there is a simple production of the machine felt.

In Ausbildung der Erfindung ist vorgesehen, daß jeweils zwei Lagen Längsfadengelege durch Umklappen eines mindestens in doppelter Länge des fertigen Maschinenfilzes hergestellten Fadengelegemoduls unter Einschluß der Einlage gebildet sind. Die Enden der Längsfäden stoßen dann vorzugsweise in der Mitte des Maschinenfilzes aneinander. Ein solcher Stoß wird vermieden, wenn die Längsfadengelege einen endlosen Längsfadengelegeschlauch bilden, der die Einlage einschließt. In diesem Fall sind die Längsfäden endlos ausgebildet. Sie können beispielsweise durch wendelförmiges Wickeln eines Längsfadens gebildet sein.In training of the invention it is provided that in each case two layers Längsfadengelege are formed by folding over a threadlaying module produced at least twice the length of the finished machine felt, including the insert. The ends of the longitudinal threads then preferably abut one another in the middle of the machine felt. Such a shock is avoided if the longitudinal thread loops form an endless longitudinal thread loop which encloses the insert. In this case, the longitudinal threads are endless. They can be formed for example by helically winding a longitudinal thread.

Die Grundstruktur des erfindungsgemäßen Maschinenfilzes läßt sich auf verschiedene Weise variieren. So besteht die Möglichkeit, daß mehr als zwei Lagen von Längsfadengelegen dadurch gebildet werden, daß mehrere Gelegeeinheiten, bestehend jeweils aus zwei Lagen Längsfadengelege mit gemeinsamen Längsfäden, vorgesehen sind. Dies kann beispielsweise in der Weise geschehen, daß wenigstens zwei Gelegeeinheiten übereinander angeordnet sind, wobei die Einlage zwischen den Lagen der Gelegeeinheiten und auch zwischen den Gelegeeinheiten selbst vorgesehen sein kann. Alternativ können die Gelegeeinheiten auch ineinander geschachtelt angeordnet sein. Zur Ausbildung der Kupplungsösen können die Längsfäden nureinerGelegeeinheit aber auch die aller Gelegeeinheiten herangezogen werden.The basic structure of the machine felt according to the invention can be varied in various ways. Thus, there is the possibility that more than two layers of longitudinal thread are formed by the fact that several scrim units, each consisting of two layers Längsfadengelege with common longitudinal threads are provided. This can for example be done in such a way that at least two scrim units are arranged one above the other, wherein the insert between the layers of scrim units and also between the scrim units can be provided itself. Alternatively, the scrim units can also be arranged nested one inside the other. To form the coupling eyelets, the longitudinal threads of only one piece of lining but also of all the pairs of pieces can be used.

Gemäß der Erfindung ist ferner vorgeschlagen, daß auf wenigstens ein Längsfadengelege außenseitig ein Querfadengelege aufgebracht ist.According to the invention it is further proposed that a Querfadengelege is applied externally on at least one Längsfadengelege.

Für die Ausbildung der Einlage kommen alle bekannten Techniken in Frage. Sie kann zusätzlich eine Faserschicht aufweisen.For the formation of the insert all known techniques come into question. It may additionally have a fiber layer.

Ein Verfahren zur Herstellung des vorgeschriebenen Maschinenfilzes ist erfindungsgemäß dadurch gekennzeichnet, daß wenigstens ein Längsfadenmodul in zumindest doppelter Länge des fertigen Maschinenfilzes hergestellt wird und daß die überstehenden Abschnitte des Längsfadenmoduls um die Stirnseiten der Einlage unter Bildung von Kupplungsösen durch die Längsfäden herumgeklappt und fixiert werden. Um das Einführen eines Kupplungssteckdrahtes zu erleichtern, sollte im Bereich der Kupplungsösen störendes Material entfernt werden, beispielsweise indem wenigstens ein stirnseitiger Querfaden der Einlage entfernt wird. Sofern dort auch Fasermaterial vorhanden ist, sollte es entfernt werden.A method for producing the prescribed machine felt according to the invention is characterized in that at least one longitudinal thread module is produced in at least twice the length of the finished machine felt and that the protruding portions of the longitudinal thread module are folded around the end faces of the insert to form coupling loops by the longitudinal threads and fixed. In order to facilitate the insertion of a coupling plug wire, interfering material should be removed in the region of the coupling eyelets, for example by removing at least one end-side transverse thread of the insert. If there is also fiber material, it should be removed.

Ein alternatives Verfahren ist dadurch gekennzeichnet, daß ein endloser Längsfadengelegeschlauch und getrennt davon die Einlage hergestellt werden und daß die Einlage in den von dem Längsfadengelegeschlauch umschlossenen Raum plaziert wird, wobei die Einlage gegenüber der Länge des Längsfadengelegeschlauches derart verkürzt ist, daß an den Stirnseiten des Längsfadengelegeschlauches von dem Längsfadengelegeschlauch gebildete Kupplungsösen entstehen. Der Längsfadengelegeschlauch kann dabei durch wendelförmiges Wickeln von wenigstens einem Längsfaden in Längsrichtung und quer dazu fortschreitend hergestellt werden. Zur Stabilisierung der Längsfadengelege sollte eine Vemadelung der Faserschichten durchgeführt werden. Die Faserschichten können ein- oder beidseitig bei oder nach der Herstellung der Längsfadengelege aufgelegt und befestigt werden. Auch an der Einlage können ein- oder beidseitig Faserschichten befestigt und dann auch vernadelt werden.An alternative method is characterized in that an endless longitudinal thread looped tube and separately from the insert are made and that the insert is placed in the space enclosed by the longitudinal thread laid tube, wherein the Insole relative to the length of the longitudinal thread laid tube is shortened so that formed on the end faces of the longitudinal thread laid tube of the Längsfadengelegeschlauch Kupplungsösen. The longitudinal thread-laid tube can be produced progressively by helically winding at least one longitudinal thread in the longitudinal direction and transversely thereto. To stabilize the longitudinal thread layer, a needling of the fiber layers should be carried out. The fiber layers can be placed on one or both sides during or after the preparation of the longitudinal thread scrim and fastened. On the insert fiber layers can be attached on one or both sides and then also needled.

Die Figuren 1 bis 4 zeigen stufenförmig die Herstellung eines endlichen Papiermaschinenfilzes 1. Zunächst werden getrennt eine Querfadeneinlage 2 und ein Längsfadenmodul 3 hergestellt. Die Querfadeneinlage 2 besteht aus einer Vielzahl nebeneinander angeordneter und untereinander verbundener Querfäden - beispielhaft mit 4 bezeichnet - deren Länge der Breite des Längsfadenmoduls 3 entsprechen. Das Längsfadenmodul 3 weist eine Vielzahl von senkrecht zur Zeichnungsebene nebeneinander angeordnete Längsfäden 5 auf, die aneinander befestigt sind und an deren Unterseite eine Faserschicht 6 angeklebt ist. Das Längsfadenmodul 3 ist in der gestreckten Stellung gemäß Fig. 1 doppelt so lang wie die Querfadeneinlage 2. Durch mittige Auflage des Längsfadenmoduls 3 auf die Querfadeneinlage 2 entstehen hierdurch überstehende Abschnitte 7, 8.FIGS. 1 to 4 show in stages the production of a finite paper machine felt 1. First, a transverse thread insert 2 and a longitudinal thread module 3 are produced separately. The transverse thread insert 2 consists of a multiplicity of side-by-side and interconnected transverse threads-designated by way of example by 4-whose length corresponds to the width of the longitudinal thread module 3. The longitudinal thread module 3 has a multiplicity of longitudinal threads 5 arranged side by side perpendicular to the plane of the drawing, which are fastened to one another and to whose underside a fiber layer 6 is glued. In the stretched position according to FIG. 1, the longitudinal thread module 3 is twice as long as the transverse thread insert 2. By means of central support of the longitudinal thread module 3 on the transverse thread insert 2, protruding sections 7, 8 are created.

In der nächsten Herstellungsstufe werden die Abschnitte 7, 8 entsprechend den Pfeilen A und B auf die Unterseite der Querfadeneinlage 2 umgeklappt, so daß die Stirnseiten der Abschnitte 7, 8 nahezu aneinanderstoßen. Diese Situation ist in Fig. 2 dargestellt. Das Vorprodukt für den späteren Papiermaschinenfilz 1 hat jetzt dessen Länge, wobei die Längsfäden 5 des Längsfadenmoduls 3 um die Stirnseiten der Querfadeneinlage 2 herumgehen. Um dort Kupplungsösen 9, 10 auszubilden, werden die außenliegenden Querfäden 11, 12 der Querfadeneinlage 2 sowie die dort vorhandene Faserschicht 6 entfernt. Hierdurch entstehen eine Vielzahl von senkrecht zur Zeichnungsebene nebeneinanderliegenden Kupplungsösen 9, 10, welche freie Einsteckkanäle 13, 14 einschließen.In the next manufacturing stage, the sections 7, 8 are folded according to the arrows A and B on the underside of the transverse thread insert 2, so that the end faces of the sections 7, 8 almost abutting. This situation is shown in FIG. The precursor for the later paper machine felt 1 now has its length, wherein the longitudinal threads 5 of the longitudinal thread module 3 go around the end faces of the transverse thread insert 2. To form there coupling eyes 9, 10, the outer transverse threads 11, 12 of the transverse thread insert 2 and the existing there fiber layer 6 are removed. This results in a plurality of perpendicular to the plane of the drawing adjacent coupling eyes 9, 10, which include free plug-in channels 13, 14.

In einem weiteren Herstellungsschritt werden auf die beiden Außenseiten des Längsfadenmoduls 3 Faserschichten 16, 17 aufgebracht, und zwar auf der Oberseite mit einer größeren Dicke als auf der Unterseite. Die Faserschichten 16, 17 und die Faserschicht 6 werden dann in einer Nadelmaschine vernadelt, wodurch die Querfadeneinlage 2 sowie die umgeklappten Abschnitte 7, 8 untereinander fixiert werden. Der Papiermaschinenfilz 1 ist dann fertig.In a further production step 3 fiber layers 16, 17 are applied to the two outer sides of the longitudinal thread module, on the upper side with a greater thickness than on the underside. The fiber layers 16, 17 and the fiber layer 6 are then needled in a needle machine, whereby the transverse thread insert 2 and the folded portions 7, 8 are fixed to each other. The paper machine felt 1 is then finished.

Zum Verbindung der Stirnseiten wird der Papiermaschinenfilz 1 in die aus Fig. 4 ersichtliche Form gebracht. Dabei überlappen sich die Kupplungsösen 9, 10, so daß ein Kupplungskanal 20 entsteht, durch den ein Kupplungssteckdraht 21 gesteckt ist. Dieserverbindet die beiden Stirnseiten. Aufgrund der Schrägen an den Stirnseiten der Faservliese 16, 17 überschneiden sich diese, so daß die Kupplungsösen 9, 10 außenseitig durch das Faservlies 16 abgedeckt sind.To connect the end faces of the paper machine felt 1 is brought into the form shown in FIG. 4. In this case, the coupling eyes overlap 9, 10, so that a coupling channel 20 is formed through which a coupling plug wire 21 is inserted. This connects the two end faces. Due to the slopes on the end faces of the fiber webs 16, 17, these overlap, so that the coupling eyes 9, 10 are covered on the outside by the fiber fleece 16.

In den Figuren 5 bis 7 ist die Herstellung eines anderen Papiermaschinenfilzes 22 dargestellt. In diesem Fall wird zunächst ein Längsfadenschlauch 23 durch wendelförmiges Wickeln eines Längsfadens 24 über zwei beabstandete Walzen hergestellt. Die einzelnen Wicklungen des Längsfadens 24 werden untereinander verbunden. Hierdurch entstehen eine Längsfadenoberlage 25 und eine Längsfadenunterlage 26.FIGS. 5 to 7 show the production of another paper machine felt 22. In this case, a longitudinal thread tube 23 is first prepared by helically winding a longitudinal thread 24 over two spaced rollers. The individual windings of the longitudinal thread 24 are interconnected. This results in a longitudinal thread upper layer 25 and a longitudinal thread support 26.

In den Zwischenraum zwischen Längsfadenoberlage 25 und Längsfadenunterlage 26 wird eine Querfadeneinlage 27 eingeschoben. Sie besteht aus einer Vielzahl von nebeneinander angeordneten und untereinander verbundenen Querfäden - beispielhaft mit 28 bezeichnet - und einer aufgenadelten Faserschicht 29. Die Längserstreckung der Querfäden 28 entspricht der sich senkrecht zur Zeichnungsebene erstreckenden Breite des Längsfadenschlauches 23. Die Querfadeneinlage 27 ist gegenüber der Länge des Längsfadenschlauches 23 derart verkürzt, daß an den Stirnseiten des Längsfadenschlauches 23 Kupplungsösen 30, 31 entstehen, die von dem Längsfaden 24 gebildet werden. Die Kupplungsösen 30, 31 umschließen freie Einsteckkanäle 32, 33. In einem darauffolgenden Verfahrensschritt werden auf die Außenseiten von Längsfadenoberlage 25 und Längsfadenunterlage 26 Faserschicthen 34, 35 aufgelegt und untereinanderund mit der Faserschicht 29 durchvemadelt. Es liegt dann der fertige Papiermaschinenfilz 22 vor.In the space between the longitudinal thread upper layer 25 and longitudinal thread pad 26, a transverse thread insert 27 is inserted. It consists of a plurality of side by side arranged and interconnected transverse threads - exemplified by 28 - and a needled fiber layer 29. The longitudinal extent of the transverse threads 28 corresponds to the plane perpendicular to the plane extending width of the longitudinal thread tube 23. The transverse thread insert 27 is opposite to the length of the longitudinal thread tube 23 so shortened that at the end faces of the longitudinal yarn tube 23 coupling eyes 30, 31st arise, which are formed by the longitudinal thread 24. The coupling eyes 30, 31 enclose free insertion channels 32, 33. In a subsequent method step, fiber layers 34, 35 are placed on the outer sides of the longitudinal thread upper layer 25 and longitudinal thread underlay 26 and are needled through one another and through the fiber layer 29. There is then the finished paper machine felt 22 before.

Um diesen Papiermaschinenfilz 22 endlos zu machen, wird der in die aus Fig. 7 ersichtliche Form gebogen, bis die Kupplungsösen 30, 31 zur Überlappung kommen und dann einen Kupplungskanal 36 einschließen. In diesen wird anschließend ein Kupplungssteckdraht 37 eingeschoben, der die Verbindung der Stirnseiten herstellt. Auch hier sind die Stirnseiten 38, 39 der Faserschicht 34 angeschrägt, so daß sie sich im Bereich der Kupplungsnaht überlappen.In order to make this paper machine felt 22 endless, the shape shown in FIG. 7 is bent until the coupling eyes 30, 31 overlap and then enclose a coupling channel 36. In these, then a coupling plug wire 37 is inserted, which establishes the connection of the end faces. Again, the end faces 38, 39 of the fiber layer 34 are chamfered so that they overlap in the region of the coupling seam.
