Definitions
- the invention relates to a paper machine screen, in particular for the sheet formation zone, with a paper and a running side, made up of at least a kind of cross threads and at least one kind interwoven with them Longitudinal threads that at least form reports with each other form two different types at intersections, using the weave pattern formed from the longitudinal and transverse threads of the paper side itself repeated between intersections of the same type and being between the two crossing points of the same type and with the formation of each another type at the intersection, the longitudinal threads from the running side to the Change paper side and vice versa.
- the sheet formation unit is in usually designed as a twin-wire form, in many cases also as a gap former. It is characteristic of the machines that the sheet formation process immediately between two paper machine screens in a relatively short drainage zone takes place. Because of this short distance and the high production speed the time for sheet formation is reduced to a few Milliseconds. During this period, the solids content or dry matter content the fiber suspension increased from approximately 1% to approximately 20% become. For paper machine screens, this means that they are very high However, drainage capacity does not have to have any markings allowed to leave in the paper and offer high fiber support.
- a related composite fabric is described for example in DE 42 29 828 C2.
- the known paper machine screen consists of two superimposed Sieve fabrics that are formed at least in one layer and by binding threads running in the transverse and / or longitudinal direction are connected to one another are, with one of the screen fabrics as a definition fabric with the mechanical properties of the composite fabric with regard to elongation and stiffness of certain formation and the other screen cloth as the reaction cloth with a higher elongation and less stiffness than the definition fabric is executed.
- binding threads do not belong to the fabric structure, but are independent components, they are as large as possible in diameter kept thin to only slightly disrupt drainage. With accordingly high loads there is then the possibility that tear the thin binding threads and the bond between the sieve fabrics comes loose.
- binding threads in a generic paper machine after EP 0 432 413 B1, which is also constructed as a composite fabric, is already suggested binding threads as two of the fabric's own threads to use and this in formation of X-shaped intersections to weave the other fabric layer to the disadvantages described to avoid in the prior art; solely by the accumulation of the Known exchange points in the transverse direction also unintentionally arises Stiffening of the known fabric.
- the object of the invention is based on paper machine screens of the aforementioned type improve that they have a longer service life in papermaking and secondly, they can be implemented cost-effectively.
- a pertinent one A paper machine screen solves the problem with the features of the claim 1.
- a shot ratio is preferably chosen from 2: 1.
- the figures partially show a screen fabric designated as a whole by 10 for a paper machine screen, not shown as a whole, in particular can be used for the so-called sheet formation zone in conventional paper making machines.
- the screen fabric 10 has a paper side 12 and one Running page 14.
- the relevant paper side 12 and the running side 14 are formed from two different types of transverse threads 16, 18 and at least one type with these interwoven longitudinal threads 20.
- the transverse threads 16, 18 form with the longitudinal threads 20 woven with them both seen in the longitudinal direction and in the transverse direction on the screen fabric 10 8-strand repeats A to H made in this repeat pattern Repeat lengthways and crossways accordingly.
- the weave pattern repeats formed from the longitudinal threads 20 and transverse threads 16 of the paper side 12, between Crossing points 22 of the same type, being between the two crossing points 22 of the same type and with the formation of the further or another type at intersection points 24, the longitudinal threads 20 from the running side 14 switch to paper page 12 and vice versa.
- the solution is to change the longitudinal threads 20 in the difference to the state of the art with formation of the further type at intersection points 24 within the respective repeat A to H of the running side 14 of the screen fabric 10.
- this repeat A to H of the running side 14 on its side facing away from the paper side 12 Outside 26 the transverse threads 18 of the running side 14 of at least two longitudinal threads 20 held.
- Binding it becomes possible to face the number of shots on paper side 12 to double the running side 14 shown. Accordingly, it follows a 2: 1 shot ratio between paper side 12 and barrel side 14 while in the known solutions usually a shot ratio of only 1: 1 is achieved.
- the thread diameters which can thus be installed on the running side 14, can thus be doubled in cross-section compared to the paper side 16 become. That in turn means that the volume of the wearing Material (deficit) and thus the running time of the sieve according to the invention on the one hand through the long-floating bond achieved and on the other significantly increased by the larger diameter on the running side 14 can be. Due to the "open" running side 14 reached, in addition the permeability of the screen fabric 10 is increased and so are the drainage properties clearly improved.
- the screen fabric 10 according to the invention is largely has a homogeneous binding pattern and a safe, equally effective Bonding is achieved in every direction of the fabric.
- the bond pattern the paper side 12 consists of a normal plain weave, the plain weave that is between intersections of the one type 22 and the immediately following other type 24, 8-stemmed is trained. Furthermore, it is provided that the running side 14 within each repeat A to H, 8 strands in both directions considered trained.
- the respective longitudinal threads 20, the cross threads 18 of the running side 14 support their outer side 26 facing away from the paper side 12, at least once adjacent in pairs (see Fig. 3) side by side arranged.
- the transverse threads 16, 18 as weft threads and the longitudinal threads 20 as warp threads train As FIG. 1 in particular shows, the crossing points are one type 22 on the running side 14 of two cross threads 18 and the crossing point the other type 24 of four transverse threads 18 towards the running side 14 considered supported, these supporting transverse threads 18 essentially in a common plane on the outside 26 of the running side 14 are arranged horizontally.
- the respective longitudinal threads 20, which are the transverse threads 18 Running side 14 on its side 28 facing paper side 12 (see FIG. 2) limit, grouped in pairs next to each other, whereby up to three Groups in the immediate neighboring facility within a repeat A to H can be present (see transverse thread 18D in Fig. 2).
- the plain weave on paper page 12 there would also be another, regular Repetitive binding pattern conceivable for the solution.
- paper side 12 and running side 14 is a unified tissue and no longer, as in the prior art Technology, a composite fabric made of separable individual fabrics.
- the paper machine screen is nevertheless built up in several layers and could in the sense of a composite fabric also expanded accordingly with fabric layers become.

Abstract
Description
Die Erfindung betrifft ein Papiermaschinensieb, insbesondere für die Blattbildungszone, mit einer Papier- und einer Laufseite, gebildet aus mindestens einer Art an Querfäden und mindestens einer Art mit diesen verwobenen Längsfäden, die miteinander unter Bildung von Rapporten mindestens zwei verschiedene Arten an Kreuzungsstellen ausbilden, wobei das Bindungsmuster gebildet aus den Längs- und Querfäden der Papierseite sich zwischen Kreuzungsstellen gleicher Art wiederholt und wobei zwischen den beiden Kreuzungsstellen gleicher Art und unter Bildung der jeweils weiteren Art an Kreuzungsstellen die Längsfäden von der Laufseite auf die Papierseite und umgekehrt wechseln.The invention relates to a paper machine screen, in particular for the sheet formation zone, with a paper and a running side, made up of at least a kind of cross threads and at least one kind interwoven with them Longitudinal threads that at least form reports with each other form two different types at intersections, using the weave pattern formed from the longitudinal and transverse threads of the paper side itself repeated between intersections of the same type and being between the two crossing points of the same type and with the formation of each another type at the intersection, the longitudinal threads from the running side to the Change paper side and vice versa.
In der Papier erzeugenden Industrie werden heute immer mehr Hochleistungs-Papiermaschinen mit Geschwindigkeiten bis zu 2000 m/min und Arbeitsbreiten über 10 m eingesetzt. Die Blattbildungseinheit ist dabei in aller Regel als Doppelsiebform ausgeführt, in vielen Fällen auch als Spaltformer. Charakteristisch für die Maschinen ist, daß der Blattbildungsvorgang sofort zwischen zwei Papiermaschinensieben in einer relativ kurzen Entwässerungszone stattfindet. Durch diese kurze Strecke und die hohe Produktionsgeschwindigkeit reduziert sich die Zeit für die Blattbildung auf einige Millisekunden. In diesem Zeitraum muß der Feststoffanteil bzw. Trokkengehalt der Faserstoffsuspension von ca. 1 % auf etwa 20 % angehoben werden. Das bedeutet für die Papiermaschinensiebe, daß sie eine sehr hohe Entwässerungsleistung besitzen müssen aber trotzdem keine Markierungen im Papier hinterlassen dürfen und eine hohe Faserunterstützung bieten.Today, more and more high-performance paper machines are used in the paper-making industry with speeds up to 2000 m / min and Working widths over 10 m used. The sheet formation unit is in usually designed as a twin-wire form, in many cases also as a gap former. It is characteristic of the machines that the sheet formation process immediately between two paper machine screens in a relatively short drainage zone takes place. Because of this short distance and the high production speed the time for sheet formation is reduced to a few Milliseconds. During this period, the solids content or dry matter content the fiber suspension increased from approximately 1% to approximately 20% become. For paper machine screens, this means that they are very high However, drainage capacity does not have to have any markings allowed to leave in the paper and offer high fiber support.
Ein weiterer wichtiger Punkt ist die Querstabilität der Siebbespannung, die maßgebend ist für die Gleichmäßigkeit des Dicken- und Feuchtigkeitsprofils der Papierbahn. Gerade bei den modernen Maschinen mit großen Arbeitsbreiten sind die diesbezüglichen Anforderungen sehr hoch angesetzt. Zur Verbesserung der Formation werden in der Blattbildungszone mithin immer häufiger Formierleisten eingesetzt, die wechselseitig auf den Laufseiten der Siebe angeordnet sind und gegen diese gedrückt werden. Dadurch kommt es zu einer schnell wechselnden, in Längsrichtung verlaufenden Durchbiegung der Bespannung der Siebe.Another important point is the cross stability of the fabric is decisive for the uniformity of the thickness and moisture profile the paper web. Especially with modern machines with large working widths the relevant requirements are set very high. to Formation improvement is therefore always in the sheet formation zone Forming strips are used more often, which alternately on the running sides of the Sieves are arranged and pressed against them. It comes there is a rapidly changing longitudinal deflection covering the sieves.
Üblicherweise versucht man heutzutage, diesen Anforderungen durch den Einsatz von Verbundgeweben gerecht zu werden. Ein dahingehendes Verbundgewebe ist beispielsweise in der DE 42 29 828 C2 beschrieben. Das dahingehend bekannte Papiermaschinensieb besteht aus zwei übereinanderliegenden Siebgeweben, die mindestens einlagig ausgebildet und durch in Quer- und/oder Längsrichtung verlaufende Bindefäden miteinander verbunden sind, wobei eines der Siebgewebe als Definitionsgewebe mit den mechanischen Eigenschaften des Verbundgewebes hinsichtlich Dehnung und Steifigkeit bestimmter Ausbildung und das andere Siebgewebe als Reaktionsgewebe mit einer höheren Dehnung und geringeren Steifigkeit als das Definitionsgewebe ausgeführt ist. Die angesprochenen Siebgewebe bestehen also aus Kett- und Schußfäden, wobei diese durch zusätzliche Bindefäden miteinander verbunden sind. Durch die Ausbildung der Siebgewebelagen als Reaktions- oder Definitionsgewebe wird dem inneren Verschleiß und insbesondere dem Verschleiß der Bindefäden entgegengetreten und derart die Lebensdauer des Verbundgewebes erhöht sowie eine ungewollte Trennung der Siebgewebelagen auch längerfristig vermieden. Der angesprochene innere Verschleiß eines Verbundgewebes ist insbesondere dadurch bedingt, daß bei den Siebumlenkungen, wie sie im Bereich von Leitwalzen der Siebpartie auftreten, über welche das Verbundgewebe geführt wird, die einzelnen Siebgewebelagen in unterschiedlichem Maße gedehnt oder gestaucht werden.Nowadays you usually try to meet these requirements with the Use of composite fabrics. A related composite fabric is described for example in DE 42 29 828 C2. The known paper machine screen consists of two superimposed Sieve fabrics that are formed at least in one layer and by binding threads running in the transverse and / or longitudinal direction are connected to one another are, with one of the screen fabrics as a definition fabric with the mechanical properties of the composite fabric with regard to elongation and stiffness of certain formation and the other screen cloth as the reaction cloth with a higher elongation and less stiffness than the definition fabric is executed. The screen fabrics mentioned exist So from warp and weft threads, these by additional binding threads are interconnected. Through the formation of the sieve fabric layers internal wear becomes the reaction or definition fabric and in particular countered the wear of the binding threads and this increases the lifespan of the composite fabric as well as an unwanted one Separation of the screen fabric layers also avoided in the long term. The one addressed internal wear of a composite fabric is particularly due to this requires that with the wire deflections, as in the area of guide rollers occur in the wire section over which the composite fabric is guided the individual sieve fabric layers are stretched to different degrees or be upset.
Da die angesprochenen Bindefäden nicht zur Gewebestruktur gehören, sondern eigenständig Bauteile sind, werden diese möglichst im Durchmesser dünn gehalten, um die Entwässerung nur geringfügig zu stören. Bei entsprechend hohen Beanspruchungen besteht dann aber die Möglichkeit, daß die dünnen Bindefäden aufreißen und der Verbund zwischen den Siebgeweben sich löst. Bei einem gattungsgemäßen Papiermaschinensieb nach der EP 0 432 413 B1, das gleichfalls als Verbundgewebe aufgebaut ist, ist zwar bereits vorgeschlagen worden, Bindefäden als zwei gewebeeigene Fäden zu verwenden und diese unter Bildung von X-förmigen Kreuzungsstellen in die jeweils andere Gewebelage einzuweben, um die beschriebenen Nachteile im Stand der Technik zu vermeiden; allein durch die Anhäufung der bekannten Wechselstellen in Querrichtung entsteht ungewollt auch eine Versteifung des bekannten Gewebes. Insbesondere über größere Weblängen kann es dann zu erheblichen Längendifferenzen kommen, die sich wiederum in Spannungsunterschieden bemerkbar machen mit der Folge, daß die die Verbindung herstellenden gewebeeigenen Bindefäden gleichfalls aufreißen und zu einem Versagen des bekannten Papiermaschinensiebes führen können. Auch ist es im Hinblick auf diese bekannte spezielle Webart im wesentlichen nur möglich, Querfäden einer Art, also Querfäden mit im wesentlichen gleichen Durchmessermaßen, sowohl für das Ober- als auch das Untergewebe zu verarbeiten, was die Möglichkeiten eines wirksamen Abstützens auf der Laufseite reduziert. Im übrigen ist die Herstellung der beschriebenen bekannten Verbundgewebe aufwendig und teuer.Since the mentioned binding threads do not belong to the fabric structure, but are independent components, they are as large as possible in diameter kept thin to only slightly disrupt drainage. With accordingly high loads there is then the possibility that tear the thin binding threads and the bond between the sieve fabrics comes loose. In a generic paper machine after EP 0 432 413 B1, which is also constructed as a composite fabric, is already suggested binding threads as two of the fabric's own threads to use and this in formation of X-shaped intersections to weave the other fabric layer to the disadvantages described to avoid in the prior art; solely by the accumulation of the Known exchange points in the transverse direction also unintentionally arises Stiffening of the known fabric. Especially over longer weaving lengths then there may be considerable differences in length again noticeable in voltage differences with the consequence that the connective tissue binding threads also tear open and to a failure of the known paper machine screen being able to lead. It is also known with regard to this particular Weave essentially only possible, cross threads of one kind, that is cross threads with essentially the same diameters, both for the upper and also process the lower fabric, giving the possibilities of an effective Support on the running side reduced. For the rest is the manufacture the known composite fabric described complex and expensive.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, Papiermaschinensiebe der vorgenannten Art derart weiter zu verbessern, daß sie über höhere Standzeiten bei der Papierherstellung verfügen und zum anderen sich kostengünstig realisieren lassen. Eine dahingehende Aufgabe löst ein Papiermaschinensieb mit den Merkmalen des Anspruches 1.Based on this prior art, the object of the invention is based on paper machine screens of the aforementioned type improve that they have a longer service life in papermaking and secondly, they can be implemented cost-effectively. A pertinent one A paper machine screen solves the problem with the features of the claim 1.
Dadurch, daß gemäß dem kennzeichnenden Teil des Patentanspruches 1 das Wechseln der Längsfäden unter Bildung der weiteren Art an Kreuzungsstellen innerhalb des jeweiligen Rapportes der Laufseite erfolgt und daß innerhalb dieses Rapportes der Laufseite auf ihrer der Papierseite abgewandten Außenseite die Querfäden der Laufseite von mindestens zwei Längsfäden gehalten sind, wird ein Maximum an papierseitiger Faserunterstützung erreicht bei geringer Markierung der Oberseite, da eine gleichmäßige Verteilung der Wechsel- oder Kreuzungsstellen erreicht ist. Da eine Lagenbindung in Längsrichtung mit allen Fäden vorhanden ist, ist darüber hinaus eine unbeabsichtigte Lagentrennung mit hoher Sicherheit vermieden.Characterized in that according to the characterizing part of claim 1 the changing of the longitudinal threads to form the further type at crossing points within the respective repeat of the running side and that within this repeat of the running side on its side facing away from the paper side Outside the cross threads of the running side of at least two Longitudinal threads are kept, a maximum of paper-side fiber support achieved with little marking of the top, since a uniform Distribution of the exchange or crossing points is reached. Because a layer bond in the longitudinal direction with all threads is beyond unintentional separation of layers avoided with high security.
Durch die Abstützung auf der Außenseite über mindestens zwei Längsfäden innerhalb eines Rapportes ist es darüber hinaus möglich, die Querfäden der Laufseite im Querschnitt dicker zu wählen als die Querfäden der Papierseite und dennoch deren sicheren Halt im Papiermaschinensieb zu gewährleisten. Hierdurch lassen sich jedoch sinnfällig die Abstützkräfte erhöhen und durch die derart gebildete relativ "offene" Laufseite ist die Entwässerungsleistung entsprechend erhöht. Vorzugsweise wählt man dabei ein Schußverhältnis von 2 : 1. Durch die langflottierende Laufseite mit ihren im Querschnitt verbreiterten Schußfäden ist darüber hinaus das Laufzeitpotential für das Papiermaschinensieb maximiert und dennoch aufgrund der beiden getrennten Schußlagen eine hohe Querstabilität erreicht.Due to the support on the outside using at least two longitudinal threads within a repeat it is also possible to cross the thread The cross-section of the running side should be thicker than the transverse threads on the paper side and still ensure their secure hold in the paper machine screen. In this way, however, the support forces can be increased and due to the relatively "open" running side formed in this way, the drainage performance increased accordingly. A shot ratio is preferably chosen from 2: 1. Through the long floating side with its cross section widened weft threads is also the runtime potential for the paper machine screen maximized and yet due to the two separate Shot positions achieved a high transverse stability.
Weitere vorteilhafte Ausführungsformen sind Gegenstand der Unteransprüche.Further advantageous embodiments are the subject of the dependent claims.

Die Figuren zeigen teilweise ein als Ganzes mit 10 bezeichnetes Siebgewebe
für ein als Ganzes nicht dargestelltes Papiermaschinensieb, das insbesondere
einsetzbar ist für die sog. Blattbildungszone bei üblichen Papierherstellmaschinen.
Das Siebgewebe 10 weist eine Papierseite 12 und eine
Laufseite 14 auf. Die dahingehende Papierseite 12 und die Laufseite 14 sind
gebildet aus zwei voneinander verschiedenen Arten an Querfäden 16,18
und mindestens einer Art mit diesen verwobenen Längsfäden 20. Die Querfäden
16,18 bilden mit den mit ihnen verwobenen Längsfäden 20 sowohl
in Längsrichtung als auch in Querrichtung auf das Siebgewebe 10 gesehen
8-schäftige Rapporte A bis H aus, die sich in diesem Rapportmuster in
Längs- und Querrichtung entsprechend wiederholen. Bei der Bildung der
dahingehenden Rapporte A bis H werden innerhalb des Siebgewebes 10
zwei verschiedene Arten an X-förmigen Kreuzungsstellen 22,24 ausgebildet
(vgl. Fig.1). Dabei verläuft ein Längsfaden 20, wie dies die Fig.1 zeigt, an
einer Kreuzungsstelle 22 der gleichen Art in der einen Richtung, also beispielsweise
mit positiver Steigung, und betreffend die Kreuzungsstelle der
anderen Art, hier 24, mit negativer Steigung.The figures partially show a screen fabric designated as a whole by 10
for a paper machine screen, not shown as a whole, in particular
can be used for the so-called sheet formation zone in conventional paper making machines.
The
Wie des weiteren die Figuren zeigen, wiederholt sich das Bindungsmuster,
gebildet aus den Längsfäden 20 und Querfäden 16 der Papierseite 12, zwischen
Kreuzungsstellen 22 gleicher Art, wobei zwischen den beiden Kreuzungsstellen
22 gleicher Art und unter Bildung der jeweils weiteren oder
anderen Art an Kreuzungsstellen 24 die Längsfäden 20 von der Laufseite 14
auf die Papierseite 12 und umgekehrt wechseln. Bei der erfindungsgemäßen
Lösung erfolgt also das Wechseln der Längsfäden 20 im Unterschied
zum Stand der Technik unter Bildung der weiteren Art an Kreuzungsstellen
24 innerhalb des jeweiligen Rapportes A bis H der Laufseite 14 des Siebgewebes
10. Ferner sind, wie dies insbesondere die Fig.3 zeigt, innerhalb
dieses Rapportes A bis H der Laufseite 14 auf ihrer der Papierseite 12 abgewandten
Außenseite 26 die Querfäden 18 der Laufseite 14 von mindestens
zwei Längsfäden 20 gehalten. Mit der dahingehenden erfindungsgemäßen
Bindung wird es möglich, die Schußzahl auf der Papierseite 12 gegenüber
der gezeigten Laufseite 14 zu verdoppeln. Demgemäß ergibt sich
ein Schußverhältnis 2 : 1 zwischen Papierseite 12 und Laufseite 14, während
bei den bekannten Lösungen in der Regel ein Schußverhältnis nur von
1 : 1 erreicht wird.As the figures also show, the weave pattern repeats,
formed from the
Die Fadendurchmesser, die sich damit auf der Laufseite 14 einbauen lassen,
können derart im Querschnitt gegenüber der Papierseite 16 verdoppelt
werden. Das bedeutet wiederum, daß das Volumen des verschleißenden
Materials (Unterschuß) und damit die Laufzeit des erfindungsgemäßen Siebes
einmal durch die erreichte langflottierende Bindung und zum anderen
durch die größeren Durchmesser auf der Laufseite 14 erheblich gesteigert
werden kann. Durch die erreichte "offene" Laufseite 14 wird darüber hinaus
die Durchlässigkeit des Siebgewebes 10 gesteigert und derart die Entwässerungseigenschaften
deutlich verbessert. Da bei dem beanspruchten Papiermaschinensieb
nach der Erfindung alle verbindenden Längsfäden 20 unmittelbar
aufeinanderfolgend angeordnet sind, gibt es im Gegensatz zu den
bekannten Gewebelösungen keinen dazwischenliegenden Oberschuß oder
Oberkette, so daß das erfindungsgemäße Siebgewebe 10 ein weitgehend
homogen ausgebildetes Bindemuster aufweist und ein sicherer, gleichwirkender
Verbund in jeder Richtung des Gewebes erreicht ist. Das Bindungsmuster
der Papierseite 12 besteht dabei aus einer üblichen Leinwandbindung,
wobei die Leinwandbindung, die zwischen Kreuzungsstellen der
einen Art 22 und der unmittelbar nachfolgenden anderen Art 24 verläuft, 8-schäftig
ausgebildet ist. Des weiteren ist vorgesehen, daß auch die Laufseite
14 innerhalb eines jeden Rapportes A bis H 8-schäftig in beiden Richtungen
betrachtet ausgebildet ist.The thread diameters, which can thus be installed on the running
Die jeweiligen Längsfäden 20, die die Querfäden 18 der Laufseite 14 auf
ihrer der Papierseite 12 abgewandten Außenseite 26 abstützen, sind zumindest
einmal paarweise benachbart (vgl. Fig.3) nebeneinanderliegend
angeordnet. Fertigungstechnisch hat es sich als besonders günstig erwiesen,
die Querfäden 16,18 als Schußfäden und die Längsfäden 20 als Kettfäden
auszubilden. Wie insbesondere die Fig.1 zeigt, sind die Kreuzungsstellen
der einen Art 22 auf der Laufseite 14 von zwei Querfäden 18 und die Kreuzungsstelle
der anderen Art 24 von vier Querfäden 18 zur Laufseite 14 hin
betrachtet abgestützt, wobei diese abstützenden Querfäden 18 im wesentlichen
in einer gemeinsamen Ebene auf der Außenseite 26 der Laufseite 14
liegend angeordnet sind.The respective
Des weiteren sind die jeweiligen Längsfäden 20, die die Querfäden 18 der
Laufseite 14 auf ihrer der Papierseite 12 zugewandten Seite 28 (vgl. Fig.2)
begrenzen, paarweise gruppiert nebeneinanderliegend, wobei bis zu drei
