Description

Die Erfindung betrifft einen Maschinenfilz mit wenigstens zwei Lagen von Längsfäden aufweisenden Längsfadengelegen und einer dazwischen angeordneten Einlage sowie mit die Außenseiten des Maschinepfilzes 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 with at least two layers of longitudinal threads having longitudinal threads and an interposed insert as well as with the Layers of fiber covering the outside of the machine mushroom. It also relates to a method of manufacture of such a machine felt, in which at least two longitudinal threads with the interposition of an insert be placed on top of each other and on the at least one fiber layer is needled.

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 in US-A-4 781,967. It is built up in modules, whereby a cross thread or between two longitudinal threads a fabric is arranged as an insert. On the outside the and between the longitudinal threads are layers of fibers intended. The individual modules are through Needling of the fiber layers connected to each other.

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 become endless manufactured. Apart from the fact that the length of such machine felts is limited, so it is not used everywhere assembly of the felt is possible for example in the press section of a paper machine difficult. The assembly of a machine felt is easier, if it is finite in length and on has coupling elements on its end faces, via which the ends of the machine felt in the machine with each other can be coupled (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 for its object a machine felt of the type mentioned in such a way that he is available in finite form and its end faces with each other are connectable.

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. 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 ergibt sich eine einfache Herstellung des Maschinenfilzes. This object is achieved according to the invention in that two layers of longitudinal thread layers have common longitudinal threads, which go over both sides of the insert and the Insert on their front sides with the formation of coupling eyes mounting. The basic idea of the invention is that is, the longitudinal threads of at least two layers of longitudinal threads around the front of the insert, so that the two layers are formed by the same longitudinal threads become. The longitudinal threads form in the area of the end faces the insert coupling eyes made for the purpose of Connection of the end faces overlapped and in this position can be coupled via a plug wire can. Except for the plug wire, there are no other special ones Coupling elements required. The through the coupling seam This causes discontinuity reduced to a minimum. It also results in a simple one 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 an embodiment of the invention it is provided that two layers of longitudinal thread scrim by folding down at least one in double length of the finished machine felt manufactured thread laying module including the insert are formed. The ends of the longitudinal threads then butt preferably in the middle of the machine felt. Such a shock is avoided if the longitudinal thread is laid form an endless lengthways lay hose, the includes the insert. In this case, the longitudinal threads are endlessly trained. For example, you can by helical winding of a longitudinal thread can be formed.

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 eine oder mehrere Einlagen zwischen den Lagen der Gelegeeinheiten und auch zwischen den Gelegeeinheiten selbst vorgesehen sein können. Alternativ können die Gelegeeinheiten auch ineinander geschachtelt angeordnet sein, wobei auch hier die Möglichkeit besteht, mehrere Einlagen zwischen den einzelnen Lagen der Gelegeeinheiten vorzusehen. Zur Ausbildung der Kupplungsösen können die Längsfäden nur einer Gelegeeinheit aber auch die aller Gelegeeinheiten herangezogen werden. The basic structure of the machine felt according to the invention can be varied in different ways. So there is the possibility that there are more than two layers of longitudinal thread are formed by the fact that several laying units, each consisting of two layers of longitudinal layers with common longitudinal threads are provided. This can for example, in such a way that at least two nesting units are arranged one above the other, whereby one or more deposits between the layers of the lay-up units and also between the layup units themselves can be provided. Alternatively, the layup units also be nested, where here too there is the possibility of multiple deposits to be provided between the individual layers of the layup units. The longitudinal threads can be used to form the coupling eyes only one lay-up unit but also that of all lay-up units 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 at least a longitudinal thread lay on the outside a cross thread lay is applied.

Für die Ausbildung der Einlage kommen alle bekannten Techniken in Frage. So kann die Einlage ein Querfadengelege aufweisen. Sie kann dabei auch mehrlagig ausgebildet sein und zusätzlich eine Faserschicht aufweisen. Auch ein Längsfadengelege kann Bestandteil der Einlage sein. Alternativ oder in Kombination dazu kommen auch ein Gewebe, Gewirke und/oder eine gelochte Folie oder auch ein Fadengitter in Frage. Zur Festlegung des Längsfadengeleges sollten die Faserschichten vernadelt sein.All known come for the formation of the insert Techniques in question. So the insert can be a cross thread exhibit. It can also be multi-layered be and additionally have a fiber layer. Also a Longitudinal laid scrims can be part of the insert. Alternatively or in combination there is also a fabric, Knitted fabrics and / or a perforated film or a thread grid in question. To determine the longitudinal thread scrim the fiber layers should be needled.

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 process for making the prescribed machine felt is characterized according to the invention in that that at least one longitudinal thread module in at least double Length of the finished machine felt is produced and that the protruding sections of the longitudinal thread module around the end faces of the insert with the formation of coupling eyes can be folded around and fixed by the longitudinal threads. To facilitate the insertion of a coupling plug wire, should be annoying in the area of the coupling eyes Material are removed, for example by at least an end cross thread of the insert is removed. If there is also fiber material there, 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. 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 Vernadelung 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 that an endless lengthways lay hose and separated of which the insert is made and that the insert in the enclosed by the longitudinal thread lay hose Space is placed. The longitudinal thread lay hose can by helically winding at least one Longitudinal thread progressing lengthways and across it getting produced. To stabilize the longitudinal laid scrim needling of the fiber layers should be carried out become. The fiber layers can be on one or both sides during or after the production of the longitudinal laid scrim be placed and fastened. Can also on the insert fiber layers attached on one or both sides and then 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.Figures 1 to 4 show the production in stages a finite paper machine felt 1. First, separated a cross thread insert 2 and a longitudinal thread module 3 manufactured. The cross thread insert 2 consists of a Large number of juxtaposed and one below the other connected transverse threads - designated by way of example at 4 - whose length corresponds to the width of the longitudinal thread module 3. The longitudinal thread module 3 has a plurality of perpendicular arranged side by side to the plane of the drawing Longitudinal threads 5, which are attached to each other and on a fiber layer 6 is glued to the underside thereof. The Longitudinal thread module 3 is in the extended position according to Fig. 1 twice as long as the cross thread insert 2. By central support of the longitudinal thread module 3 on the cross thread insert 2 this results in projecting sections 7, 8th.

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 stage of manufacture, the sections 7, 8 according to arrows A and B on the bottom the cross thread insert 2 folded so that the end faces of the sections 7, 8 almost meet. This situation is shown in Fig. 2. The preliminary product for the later paper machine felt 1 now has its length, the longitudinal threads 5 of the longitudinal thread module 3 around the Walk around the end faces of the cross thread insert 2. To there To form coupling eyes 9, 10, the outer Cross threads 11, 12 of the cross thread insert 2 and the existing fiber layer 6 removed. This creates a variety of perpendicular to the plane of the drawing Adjacent coupling eyes 9, 10, which free Include insertion 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 manufacturing step, the two Outside of the longitudinal thread module 3 fiber layers 16, 17 applied, on the top with a larger Thick than on the bottom. The fiber layers 16, 17 and the fiber layer 6 are then in a needle machine needled, whereby the cross thread insert 2 as well the folded sections 7, 8 fixed to each other become. 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. Dieser verbindet 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.The paper machine felt is used to connect the end faces 1 brought into the form shown in FIG. 4. Here overlap the coupling eyes 9, 10, so that a Coupling channel 20 arises through which a coupling plug wire 21 is inserted. This connects the two end faces. Because of the bevels on the end faces of the non-woven fabrics 16, 17 overlap, so that the Coupling eyes 9, 10 on the outside through the fiber fleece 16 are covered.

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.In Figures 5 to 7 is the manufacture of another Paper machine felt 22 shown. In this case first a longitudinal thread hose 23 by helical Winding a longitudinal thread 24 over two spaced rollers manufactured. The individual windings of the longitudinal thread 24 are interconnected. This creates a longitudinal thread upper layer 25 and a longitudinal thread underlay 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 untereinander und mit der Faserschicht 29 durchvernadelt. Es liegt dann der fertige Papiermaschinenfilz 22 vor.In the space between the top thread 25 and A cross thread insert 27 is inserted into the longitudinal thread support 26. It consists of a large number of side by side arranged and interconnected cross threads - exemplified with 28 - and a needled Fiber layer 29. The longitudinal extension of the transverse threads 28 corresponds to that extending perpendicular to the plane of the drawing Width of the longitudinal thread tube 23. The cross thread insert 27 is compared to the length of the longitudinal thread hose 23 shortened so that on the end faces of the Longitudinal thread hose 23 coupling eyes 30, 31 arise, which are formed by the longitudinal thread 24.
