Description

Die Erfindung betrifft ein als Verbundgewebe ausgebildetes Papiermaschinensieb mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a paper machine screen designed as a composite fabric with the features of the preamble of claim 1.

Im modernen Papiermaschinenbau hat sich in den letzten Jahren der sogenannte Gap- oder Spaltformer im Blattbildungsbereich eindeutig durchgesetzt. In diesem Typ der Papiermaschine wird im Blattbildungsbereich der aus dem Stoffauflauf austretende Strahl der Papierfasersuspension in den Spalt zwischen Zwei zusammenlaufenden Sieben gepumpt und auf kürzester Strecke entwässert. Aufgabe der Siebe und Entwässerungselemente der Siebpartie ist es, auf einer Entwässerungsstrecke die zwischen 0,5 und maximal 5 m die durch den Stoffauflauf definierte Formation des Papierblattes störungsfrei einzufrieren und den Trockengehalt des Papierblattes von ca. 0,5% auf Werte um die 15% zu steigern.In modern paper machine construction, the so-called Gap or gap formers are clearly enforced in the sheet formation area. In This type of paper machine is used in the sheet formation area Headbox emerging jet of the paper fiber suspension in the gap between Two converging sieves pumped and drained over the shortest distance. The task of the screens and drainage elements of the screen section is to a drainage section between 0.5 and a maximum of 5 m through the Freeze the defined formation of the paper sheet without problems and the dry content of the paper sheet from approx. 0.5% to values around 15% increase.

Aufgrund der extrem kurzen Entwässerungsstrecke ist für ein Entwässerungssieb an diesen Siebpositionen eine hohe Offenheit notwendig, die den ungehinderten Druchtritt des Wassers sicherstellt, um den Ansprüchen dieser Position gerecht zu werden. Gleichzeitig wird eine feinmaschige ebene Sieboberfläche notwendig, damit keine Markierung auftritt und eine hohe Faserretention sichergestellt wird. Der mit einem Überdruck von mehreren Bar austretende Stoffstrahl erfordert ein Sieb mit höchster Längs- und Querstabilität zur Erzeugung einer homogenen Papierbahn. Die hohen Maschinengeschwindigkeiten bis zu 2000 m/min in Verbindung mit den Siebumlenkungen über den Walzen in der Siebpartie verlangen ein Siebgewebe mit geringer Wasserspeicherkapazität, damit das durch die Zentrifugalkräfte aus dem Sieb herausgeschleuderte Wasser, welches zu einem die Produktion störenden Wassernebel formiert, auf ein Minimum beschränkt wird.Due to the extremely short drainage distance is for a drainage screen a high degree of openness is necessary at these sieve positions, Passage of water ensures to meet the demands of this position to meet. At the same time, a fine-meshed, flat screen surface necessary so that no marking occurs and a high fiber retention is ensured becomes. The jet of material escaping with an overpressure of several bars requires a sieve with maximum longitudinal and transverse stability for production a homogeneous paper web. The high machine speeds up to 2000 m / min in connection with the wire deflections over the rollers in the Sieve section require a sieve fabric with a low water storage capacity, so that the centrifugal forces throw it out of the sieve Water that forms into a water mist that disrupts production a minimum is limited.

Diese Anforderungen an die Siebbespannung können mit den bekannten Gewebetypen nur unvollständig erfüllt werden. Aus der DE 33 05 713 C1 ist beispielsweise ein Papiermaschinensieb der eingangs genannten Art bekannt, bei dem das Obergewebe und das Untergewebe durch Bindekett- und Bindeschußfäden miteinander verbunden sind. Dieses bekannte Papiermaschinensieb kann zwar die geforderten Stabilitätskriterien erfüllen, jedoch reichen seine Entwässerungseigenschaften nicht aus.These requirements for the fabric can be met with the known Tissue types can only be met incompletely. From DE 33 05 713 C1 for example, a paper machine screen of the type mentioned is known, in which the upper fabric and the lower fabric by binding warp and binding weft threads are interconnected. This well-known paper machine screen can meet the required stability criteria, but its are sufficient Drainage properties do not rule out.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Papiermaschinensieb der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß gelöst durch ein Papiermaschinensieb mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The invention is therefore based on the object of a paper machine screen to improve the type mentioned at the beginning. This object is achieved according to the invention solved by a paper machine screen with the features of claim 1. Advantageous refinements are the subject of the dependent claims.

Der Gegenstand der Erfindung kombiniert in idealer Weise die Eigenschaften eines einlagigen Siebes, welches sehr gute Entwässerungseigenschaften zeigt, mit einem mehrlagigen Sieb, das die geforderten Stabilitätskriterien erfüllt, auf der Basis eines Verbundgewebes. Unter den bekannten Siebgewebekonstruktionen bilden die Verbundgewebe unter dem Aspekt, daß man die Siebe gleicher Längs- und Querfadenzahl mit vergleichbaren Fadendurchmessern vergleicht, die Klasse von Geweben, die höchste Längs- und Querstabilität aufweisen. The object of the invention ideally combines the properties of a single-layer screen, which shows very good drainage properties, with a multi-layer sieve that meets the required stability criteria the basis of a composite fabric. Among the well-known sieve mesh constructions form the composite fabrics under the aspect that the sieves are the same Compares the number of longitudinal and transverse threads with comparable thread diameters, the class of fabrics that have the highest longitudinal and lateral stability.

Dadurch, daß obere Kettfäden die Bindefäden bilden, erhält das Papiermaschinensieb Eigenschaften in Bezug auf die Entwässerung, wie sie sonst nur bei einlagigen Sieben auftreten. Während die bekannten Bindefäden im Siebvolumen offene Räume füllen und damit den schnellen Abfluß des Wassers aus der Papierbahn stören, stehen nunmehr durch die erfindungsgemäße Ausbildung diese offenen Räume für eine schnelle Entwässerung zur Verfügung. Da die bekannten Bindefäden zur Vermeidung von Störungen im Obergewebe wesentlich dünner als die anderen Fäden ausgeführt sind, wird ferner durch die erfindungsgemäße Ausbildung mit in der Regel dickeren oberen Kettfäden die Festigkeit der Verbindung zwischen dem Obergewebe und dem Untergewebe verbessert. Eine Delaminierung der Gewebe aufgrund der hohen Biegewechselbelastungen des Siebes beim Umlauf in der Papiermaschine wird dadurch ausgeschlossen. Schließlich vereinfacht sich durch den Wegfall der gesonderten Bindefäden auch der Herstellungsprozeß, und zwar sowohl beim Rüsten der Webmaschine als auch bei Weben.The fact that upper warp threads form the binding threads gives the paper machine fabric Properties in terms of drainage, as they otherwise only single-layer seven occur. While the well-known binding threads in the screen volume fill open spaces and thus the rapid drainage of water from the Disrupt paper web, are now due to the inventive design these open spaces are available for quick drainage. Since the known binding threads to avoid disturbances in the upper fabric essential are made thinner than the other threads, is further by the inventive Training with usually thicker upper warp threads Strength of the connection between the upper fabric and the lower fabric improved. Delamination of the tissues due to the high bending stresses of the sieve in circulation in the paper machine locked out. Finally, by eliminating the separate Twine also the manufacturing process, both when setting up the Weaving machine as well as weaving.

Zur Vermeidung von Störungen der Entwässerungscharakteristik des Obergewebes ist es von Vorteil, wenn die Anzahl der oberen Kettfäden und der unteren Kettfäden übereinstimmt, während die Anzahl der oberen Schußfäden doppelt so groß ist wie die Anzahl der unteren Schußfäden. Es sind aber auch andere Fadendichten in den Gewebelagen und Webrichtungen möglich. Eine weitere vorteilhafte Maßnahme zur Vermeidung von Störungen der Entwässerungscharakteristik und der Glattheit des Obergewebes ist es, den oberen Kettfaden an denjenigen Stellen an das Untergewebe anzubinden, an denen er auf der Unterseite des Obergewebes flottierend geführt wird.To avoid disturbances in the drainage characteristics of the upper fabric it is advantageous if the number of upper warp threads and the lower one Warp matches, while the number of top wefts doubles is as large as the number of lower wefts. But there are also others Thread densities possible in the fabric layers and weaving directions. Another advantageous measure to avoid disturbances in the drainage characteristics and the smoothness of the upper fabric is to attach the upper warp thread tie those places to the lower tissue where it is on the Underside of the upper fabric is floated.

Ein vorteilhaftes Abriebverhalten und damit eine längere Lebensdauer des Siebes bei gleichzeitiger Glattheit des Obergewebes und Stabilität des Untergewebes ergibt sich, wenn die Durchmesser der Fäden des Untergewebes größer sind als die Durchmesser der korrespondierenden Fäden des Obergewebes. Es sind aber auch alle Kombinationen anderer Durchmesserverhältnisse möglich. Ein vorteilhafter Schutz der oberen Kettfäden bei gleichzeitiger Erhöhung der Festigkeit der Verbindung ergibt sich, wenn die unteren Kettfäden paarweise geführt sind, und die oberen Kettfäden an den Abbindungspunkten zwischen die paarweise geführten unteren Kettfäden eingeklemmt sind.An advantageous abrasion behavior and thus a longer life of the Sieve with simultaneous smoothness of the upper fabric and stability of the lower fabric results when the diameter of the threads of the lower fabric is larger are as the diameter of the corresponding threads of the upper fabric. It however, all combinations of other diameter ratios are also possible. An advantageous protection of the upper warp threads while increasing the Strength of the connection arises when the lower warp threads are in pairs are guided, and the upper warp threads at the binding points between the lower warp threads guided in pairs are pinched.

Ein als Verbundgewebe ausgebildetes Papiermaschinensieb besteht aus einem Obergewebe 1 und einem Untergewebe 2. Das Obergewebe 1 weist mehrere obere Kettfäden 3 in Längsrichtung des Papiermaschinensiebes sowie mehrere obere Schußfäden 5 in Querrichtung des Papiermaschinensiebes auf. Die Kettfäden 3 flottieren über mehrere, vorzugsweise drei Schußfäden 5 hinweg. Das Untergewebe 2 besteht aus mehreren in Siebquerrichtung verlaufenden unteren Schußfäden 6 sowie mehreren in Sieblängsrichtung verlaufenden unteren Kettfäden 8. Die Anzahl der oberen Kettfäden 3 entspricht der Anzahl der unteren Kettfäden 8, während doppelt soviele obere Schußfäden 5 wie untere Schußfäden 6 vorhanden sind. Die oberen Schußfäden 5 sind von geringerem Durchmesser als die unteren Schußfäden 6.A paper machine screen formed as a composite fabric consists of a Upper fabric 1 and a lower fabric 2. The upper fabric 1 has several upper warp threads 3 in the longitudinal direction of the paper machine wire and several upper wefts 5 in the transverse direction of the paper machine screen. The Warp threads 3 float over several, preferably three weft threads 5. The lower fabric 2 consists of several in the transverse direction of the sieve lower wefts 6 and several extending in the longitudinal direction of the wire lower warp threads 8. The number of upper warp threads 3 corresponds to the number of the lower warp threads 8, while twice as many upper weft threads 5 as lower wefts 6 are present. The top wefts 5 are from smaller diameter than the lower weft threads 6.

Die Oberseite des Obergewebes 1 bildet die Blattbildungsseite des Papiermaschinensiebes, während die Unterseite des Obergewebes 1 der Oberseite des Untergewebes 2 zugewandt ist. Die Unterseite des Untergewebes 2 wiederum bildet die Laufseite des Papiermaschinensiebes.The top of the upper fabric 1 forms the sheet formation side of the paper machine screen, while the bottom of the upper fabric 1 the top of the lower fabric 2 is facing. The underside of the lower fabric 2 in turn forms the running side of the paper machine screen.

In jeden zweiten Bereich, in dem der obere Kettfaden 3 auf der Unterseite des Obergewebes 1 flottiert, d.h. auf der Unterseite der oberen Schußfäden 5 flottiert, ist der Kettfaden 3 bis zum Untergewebe 2 geführt und um einen unteren Schußfaden 6 gekröpft. Dadurch sind das Obergewebe 1 und das Untergewebe 2 miteinander verbunden.In every second area in which the upper warp thread 3 on the underside of the Upper fabric 1 floated, i.e. on the underside of the top wefts 5 floated, the warp thread 3 is guided to the lower fabric 2 and around one lower weft 6 cranked. As a result, the upper fabric 1 and Lower fabric 2 joined together.

Die unteren Kettfäden 8 sind paarweise parallel geführt. An den Anbindungspunkten eines oberen Kettfadens 3 an einen unteren Schußfaden 6 ist je ein Paar von unteren Kettfäden 8 in gleicher Richtung wie der obere Kettfaden 3 um den unteren Schußfaden 6 gekröpft. Dabei ist der obere Kettfaden 3 zwischen das Paar von unteren Kettfäden 8 eingeklemmt. Insbesondere, wenn der Durchmesser des oberen Kettfadens 3 geringer ist als der Durchmesser der unteren Kettfäden 8, wird der obere Kettfaden 3 auf diese Weise optimal gegen den laufseitigen Abrieb abgeschirmt.The lower warp threads 8 are guided in parallel in pairs. At the connection points an upper warp thread 3 to a lower weft thread 6 is one Pair of lower warp threads 8 in the same direction as the upper warp thread 3 cranked around the lower weft 6. The upper warp thread 3 is between the pair of lower warp threads 8 are pinched. Especially if the Diameter of the upper warp thread 3 is less than the diameter of the lower warp threads 8, the upper warp thread 3 is optimally against this shielded the abrasion on the barrel side.

Die oberen Kettfäden 3 sind in Gruppen so angeordnet, daß nur jeder vierte obere Kettfaden 3 an das Untergewebe 2 anbindet. Ein Teil der Gewebemaschen des Obergewebes 1 wird daher nicht durch die Fäden 6, 8 des Untergewebes 2 bei senkrechter Durchsicht abgeschattet.The upper warp threads 3 are arranged in groups so that only every fourth connects the upper warp thread 3 to the lower fabric 2. Part of the mesh of the upper fabric 1 is therefore not by the threads 6, 8 of the lower fabric 2 shaded when viewed vertically.
