Description

Die vorliegende Erfindung betrifft ein aus mehreren textilen Untereinheiten geflochtenes Papierführungsseil.The present invention relates to a paper guide rope braided from several textile subunits.

Papierführungsseile dienen dazu, die entstehende Papierbahn durch das Walzensystem in den verschiedenen Sektionen (z.B. Trockengruppe, Leimpressen, Aufwickler) der Papiermaschine zu führen. Dazu laufen in der Regel zwei oder drei Papierführungsseile eng nebeneinander und die sogenannte Papierspitze wird zwischen diesen Seilen eingeklemmt und so kontrolliert durch die Sektionen geführt. Die Papierführungsseile werden in einem Kreislauf geführt, d.h. die Seilenden eines Seiles werden ineinander gespleißt, sodass sich ein Seilring ergibt, dessen Länge von der Sektion der Papiermaschine abhängt, aber üblicherweise in einer Größenordnung von 50 bis 100m liegt.Paper guide ropes serve to guide the resulting web through the roll system in the various sections (e.g., dryer section, size presses, rewinder) of the paper machine. For this purpose, usually run two or three paper guide ropes close together and the so-called paper tip is clamped between these ropes and guided as controlled by the sections. The paper guide ropes are circulated, i. the rope ends of a rope are spliced together to form a rope ring whose length depends on the section of the paper machine, but is usually on the order of 50 to 100 meters.

Papierführungsseile weisen typisch einen Durchmesser von 6 bis 17mm auf. Ihre wesentlichen Eigenschaften resultieren aus der Anwendung: Die Haftung bzw. die Klemmkraft zwischen Seil und Papier muss hoch genug sein, damit das Aufführen der Papierspitze möglich ist. Aufgrund der Länge des Seilrings darf die Dehnung des Seiles nicht hoch sein. Bruchfestigkeiten spielen eine untergeordnete Rolle, kritisch ist allerdings die Lebensdauer unter den widrigen Bedingungen einer Papiermaschine.Paper guide ropes typically have a diameter of 6 to 17mm. Their essential properties result from the application: The adhesion or the clamping force between the rope and the paper must be high enough to enable the paper tip to be guided. Due to the length of the rope ring, the elongation of the rope must not be high. Breaking strength plays a minor role, but critical is the life under the adverse conditions of a paper machine.

Die Lebensdauer von Papierführungsseilen in Papiermaschinen ist begrenzt. Je nach Sektion (d.h. Einsatzort) in der Papiermaschine ist die Lebensdauer eines Seiles länger oder kürzer. Die Seile sind verschiedenen Einflüssen wie Hitze, Feuchte, Chemikalien und insbesondere Scheuerstellen ausgesetzt. Besonders problematische Sektionen sind die Leimpressen, wo sich Chemikalien auf den Seilrollen ablagern und die Papierführungsseile mit so entstehenden Verkrustungen in Kontakt kommen, also besonders starker Abrasion ausgesetzt sind.The life of paper guide ropes in paper machines is limited. Depending on the section (i.e., job site) in the paper machine, the life of a rope is longer or shorter. The ropes are exposed to various influences such as heat, humidity, chemicals and especially chafing. Particularly problematic sections are the size presses, where chemicals are deposited on the rope pulleys and the paper guide ropes come into contact with encrustations that are created in this way, ie they are exposed to particularly strong abrasion.

Es gab bereits verschiedene Ansätze, die Lebensdauer der Papierführungsseile durch ihren Aufbau zu verlängern.There have been various approaches to extend the life of the paper guide ropes by their construction.

In der EP 0 150 702 A wird dazu eine sogenannte "Bewehrung" des Seiles mit Monofilen vorgeschlagen. Unter "Bewehrung" versteht man eine Umwicklung, Umflechtung, Umstrickung etc. des Seiles, oder des zur Herstellung des Seiles verwendeten Fasermaterials bzw. aus diesem Fasermaterial hergestellten Untereinheiten des Seiles, wobei jedoch die Oberfläche des Fasermaterials, des Seiles bzw. der Untereinheit nicht vollständig abgedeckt wird.In the EP 0 150 702 A For this purpose, a so-called "reinforcement" of the rope with monofilaments is proposed. "Reinforcement" means a wrapping, braiding, knitting, etc. of the rope, or of the fiber material used for the production of the rope or made of this fiber material subunits of the rope, but the Surface of the fiber material, the rope or the subunit is not completely covered.

In der WO 06/55995 A sowie der AT 503.289 B werden weitere Details von Bewehrungen für Papierführungsseile beschrieben.In the WO 06/55995 A as well as the AT 503.289 B Further details of reinforcements for paper guide ropes are described.

Aus der US 2005/0204909 sind Papierführungsseile bekannt, in welchen zunächst ein Multifilamentzwirn mit einem Monofilament umzwirnt wird, also auf dem Multifilamentzwirn eine Bewehrung hergestellt wird. Der bewehrte Multifilamentzwirn wird dann zu kleinen Seilchen geflochten, aus welchen wiederum das Papierführungsseil geflochten wird. Alternativ beschreibt die US 2005/0204909 die Herstellung eines Seiles, in welchem die Bewehrung (Umzwirnung mit einem Monofilament) nicht am ursprünglichen Multifilamentzwirn, sondern an den aus diesem Zwirn geflochtenen kleinen Seilchen angebracht wird.From the US 2005/0204909 paper guide ropes are known in which a multifilament thread is first twisted with a monofilament, so on the multifilament thread reinforcement is made. The reinforced multifilament thread is then braided into small ropes, from which in turn the paper guide rope is braided. Alternatively, the describes US 2005/0204909 the manufacture of a rope in which the reinforcement (a monofilament twist) is attached not to the original multifilament thread but to the small rope braided from this thread.

Allen diesen Vorschlägen ist gemeinsam, dass auf das Seil oder auf eines seiner Elemente (ursprünglicher Zwirn, aus dem Zwirn hergestellte Untereinheit wie z.B. kleines Seilchen) eine Bewehrung aufgebracht wird.All of these proposals have in common that a reinforcement is applied to the rope or to one of its elements (original twist, subassembly made from the twist such as small rope).

Zur Herstellung von Bewehrungen eingesetzte Monofile haben die Eigenschaft, im Einsatz bald zu brechen und das Seil unansehnlich zu machen. Das Seil sieht augenscheinlich verschlissen aus, obwohl es durchaus noch eine lange Lebensdauer hätte. In den Papiermaschinen werden die Seile aber in der Regel nach ihrem Aussehen beurteilt und wird gemäß ihrem Aussehen über den Austausch entschieden.Monofilaments used to make reinforcements have the property of breaking soon in use and rendering the rope unsightly. The rope looks obviously worn, although it would still have a long life. In the paper machines, however, the ropes are usually judged by their appearance and are decided according to their appearance on the exchange.

Eine weitere wichtige Eigenschaft von Papierführungsseilen ist ihre Dehnung. Die Seile müssen während ihres Einsatzes gespannt werden und bleiben. Dehnt sich ein Papierführungsseil, so wird diese Längenänderung mit Hilfe einer Spannstation ausgeglichen, sodass die Spannung des Seiles gleich bleibt. Der Spannweg der Spannstation ist aber in der Regel beschränkt. Eine zu hohe Dehnung des Seiles führt also dazu, dass es nicht mehr gespannt werden kann, dadurch vermehrtem Verschleiß ausgesetzt ist und auch aus seiner Bahn herausspringen kann und daher ausgewechselt werden muss. Die bekannten Seile mit einer Bewehrung aus Monofilen weisen eine vergleichsweise hohe Dehnung auf, die konstruktiv bedingt ist.Another important feature of paper guide ropes is their elongation. The ropes must be stretched during their use and stay. If a paper guide rope stretches, this change in length is compensated by means of a tensioning station so that the tension of the rope remains the same. The tensioning of the tensioning station is usually limited. Too high an elongation of the rope thus means that it can no longer be tensioned, is thus exposed to increased wear and can also jump out of its orbit and therefore has to be replaced. The known ropes with a reinforcement of monofilaments have a relatively high elongation, which is constructive.

Aus der CZ 19446 U1 ist ein Seil bekannt, welches aus einer Mehrzahl von textilen Untereinheiten, die jeweils aus lediglich nebeneinanderliegenden Garnen bestehen, geflochten wird. Die Garne sind dabei nicht gedreht. Dadurch entsteht ein Seil mit vergleichweise geringer Dehnung.From the CZ 19446 U1 a rope is known, which consists of a plurality of textile subunits, each consisting of only adjacent yarns, is braided. The yarns are not turned. This creates a rope with comparatively low elongation.

Aus der EP 0 808 943 A1 ist ein aus einer Mehrzahl von textilen Untereinheiten geflochtenes Papierführungsseil gemäss dem Oberbegriff des Anspruchs 1 bekannt.From the EP 0 808 943 A1 is known from a plurality of textile subunits braided paper guide rope according to the preamble of claim 1.

Die vorliegende Erfindung stellt sich zur Aufgabe, ein Papierführungssseil zur Verfügung zu stellen, welches eine wesentlich höhere Abrasionsbeständigkeit als herkömmliche Papierführungsseile und gleichzeitig eine ausreichend geringe Dehnung aufweist. Insbesondere soll das Papierführungsseil aus den beschriebenen Gründen keine Bewehrung aufweisen.The present invention has as its object to provide a paper guide rope, which has a much higher abrasion resistance than conventional paper guide ropes and at the same time a sufficiently low elongation. In particular, the paper guide rope should have no reinforcement for the reasons described.

Diese Aufgabe wird mit einem aus einer Mehrzahl von textilen Untereinheiten geflochtenem Papierführungsseil gemäss Anspruch 1 gelöst.This object is achieved with a paper guide rope braided from a plurality of textile subunits according to claim 1.

Kurze Beschreibung der FigurenBrief description of the figures

  • Figur 1 zeigt eine Ausführungsform eines geflochtenen Papierführungsseiles FIG. 1 shows an embodiment of a braided paper guide rope
  • Figur 2 zeigt eine weitere Ausführungsform eines geflochtenen Papierführungsseiles FIG. 2 shows another embodiment of a braided paper guide rope
Detaillierte Beschreibung der ErfindungDetailed description of the invention

Es wurde gefunden, dass Papierführungsseile, deren textile Untereinheiten nicht aus dicken Zwirnen (mit einer Dicke von z.B. 8400 dtex pro Zwirn) mit einer relativ geringen Drehung (typischerweise etwa 80 T/m) aufgebaut sind, sondern aus relativ dünnen Zwirnen mit einer sehr hohen Drehung, hervorragende Eigenschaften hinsichtlich der Abrasionsbeständigkeit bei gleichzeitig guten Dehnungseigenschaften aufweisen.It has been found that paper guide ropes whose textile subunits are not constructed of thick twines (with a thickness of eg 8400 dtex per twist) with a relatively small twist (typically about 80 T / m) but of relatively thin twists with a very high twist Rotation, have excellent properties in terms of abrasion resistance with good elongation properties.

Im erfindungsgemäßen Seil besteht insbesondere keine Notwendigkeit, eine zusätzliche Bewehrung vorzusehen, sodass gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung weder das Seil noch die Untereinheiten bzw. deren Zwirne eine Bewehrung aufweisen.In the rope according to the invention, in particular, there is no need to provide an additional reinforcement, so that according to a preferred embodiment of the present invention, neither the rope nor the sub-units or their threads have a reinforcement.

Die Drehung der Zwirne im erfindungsgemäßen Seil kann jeweils 150 T/m bis 350 T/m, bevorzugt 150 T/m bis 250 T/m, insbesondere bevorzugt 200 T/m betragen.The rotation of the threads in the rope according to the invention can be in each case 150 T / m to 350 T / m, preferably 150 T / m to 250 T / m, particularly preferably 200 T / m.

Der Titer der Zwirne im erfindungsgemäßen Seil kann jeweils 400 dtex bis 5000 dtex, bevorzugt 2500 dtex bis 4500 dtex, besonders bevorzugt 4200 dtex betragen.The denier of the twines in the rope according to the invention can be in each case 400 dtex to 5000 dtex, preferably 2500 dtex to 4500 dtex, particularly preferably 4200 dtex.

Das textile Material zumindest eines Teils der Zwirne besteht aus Polyamid. Es können aber auch Garnmischungen vorgesehen sein. So kann beispielsweise ein Zwirn mit 3 Litzen aus einem Garn aus Polyamid und zwei Garnen eines anderen Materials, z.B. Polyester, bestehen.The textile material of at least part of the threads is made of polyamide. But it can also be provided yarn mixtures. For example, a 3-strand twisted yarn may be made of a yarn of polyamide and two yarns of another material, e.g. Polyester, consist.

Die Multifilamentgarne bzw. die daraus hergestellten Zwirne können gegebenenfalls in an sich bekannter Weise imprägniert und/oder thermofixiert sein. Auch das gesamte Seil kann in an sich bekannter Weise imprägniert und/oder thermofixiert sein.The multifilament yarns or the threads made therefrom may optionally be impregnated in a manner known per se and / or heat-set. Also, the entire rope can be impregnated in a conventional manner and / or heat-set.

Die Anzahl der Zwirne pro Untereinheit beträgt bevorzugt zumindest 7, besonders bevorzugt 9 bis 16.The number of threads per subunit is preferably at least 7, more preferably 9 to 16.

Unter dem Begriff "Untereinheit" werden für die Zwecke der vorliegenden Erfindung jene Ansammlungen an Fasermaterial verstanden, die im Seil parallel und nebeneinander zu liegen kommen, wie z.B. eine Mehrzahl nebeneinander liegender Zwirne, geflochtener Zwirne oder gedrehter Zwirne.For the purposes of the present invention, the term "subunit" is understood to mean those accumulations of fiber material which lie parallel and next to one another in the cable, such as e.g. a multitude of threads lying side by side, plaited twines or twisted threads.

Zur Demonstration des Begriffes "Untereinheit" zeigen die Figuren 1 und 2 zwei verschiedene Ausführungsformen eines Papierführungsseiles 1.To demonstrate the term "subunit" show the Figures 1 and 2 two different embodiments of a paper guide rope. 1

In der Ausführungsform gemäß Figur 1 ist das Seil 1 aus Untereinheiten 2 (hier: Flechtrauten) aufgebaut, die jeweils mehr als sieben Zwirne 3 enthalten. Diese Untereinheiten 2 können jeweils mittels zweier hintereinander laufenden Klöppeln erzeugt werden, woraus die Form einer Flechtraute resultiert (in Figur 1 umrahmt). In den Untereinheiten liegen die Zwirne im wesentlichen parallel nebeneinander.In the embodiment according to FIG. 1 the rope 1 is made up of subunits 2 (here: braid rhombuses), each containing more than seven threads 3. These subunits 2 can each be produced by means of two bobbins running one behind the other, from which the shape of a braided diamond results (in FIG FIG. 1 framed). In the subunits, the threads are essentially parallel to each other.

In der Ausführungsform gemäß Figur 2 ist das Seil 1 ebenfalls aus Untereinheiten 2 aufgebaut, die jeweils mittels zweier Klöppeln hergestellt werden. Es resultieren jeweils zwei zumindest zum Teil nebeneinander liegende Elemente 2', 2" (die in Figur 2 umrahmt sind). Die aus den nebeneinander liegenden Abschnitten der beiden Elementen 2', 2" bestehende Untereinheit 2 weist erneut zumindest sieben Zwirne auf. Auch in dieser Ausführungsform liegen die Zwirne in den Untereinheiten 2 bzw. deren Elementen 2', 2" im wesentlichen nebeneinander.In the embodiment according to FIG. 2 the rope 1 is also constructed of subunits 2, which are each manufactured by means of two bobbins. This results in each case two at least partially adjacent elements 2 ', 2 "(which in FIG. 2 framed). The subunit 2 consisting of the juxtaposed sections of the two elements 2 ', 2 "again has at least seven threads, also in this one Embodiment are the threads in the subunits 2 and their elements 2 ', 2 "substantially side by side.

Sinngemäß ist diese Definition der Untereinheit auch auf Ausführungsformen anwendbar, die durch das Hintereinanderlaufen von mehr als zwei Klöppeln in die beiden Laufrichtungen S und Z entstehen. Eine derartige Seilkonstruktion ist auf den gängigen Flechtmaschinen heute allerdings nicht vorgesehen.Analogously, this definition of the subunit is also applicable to embodiments that result from the consecutive running of more than two bobbins in the two directions S and Z. However, such a rope construction is not provided on the current braiding today.

Das erfindungsgemäße Papierführungsseil kann in Form eines Hohlseiles oder auch eines Seiles mit Kern vorliegen.The paper guide rope according to the invention may be in the form of a hollow rope or a rope with a core.

Messmethode der Trockendehnung:Measuring method of dry elongation:

Bei 1kg Last wird 1m Seil markiert. Dann wird eine Last von 80 kg aufgebracht, 5 min belastet und anschließend die Längung abgelesen. Längung in cm = Dehnung in %At 1kg load 1m rope is marked. Then a load of 80 kg is applied, loaded for 5 minutes and then read the elongation. Elongation in cm = elongation in%

Messmethode der Nassdehnung:Measuring method of wet stretch:

Wie Trockendehnung, aber nach dem Markieren von 1m Seil wird das Seil 5 min in 25°C kaltes Wasser gelegt.Like dry stretch, but after marking 1m rope, the rope is placed in 25 ° C cold water for 5 min.

Die an den obigen Seilen 1) bis 4) gemessenen Dehnungswerte sind in der folgenden Tabelle dargestellt: Trockendehnung Nassdehnung % % Seil 1) (erfindungsgemäß) 2,4 4,4 Seil 2) 1,8 3,5 Seil 3) 1,9 3,5 Seil 4) 2,8 4,5 The elongation values measured on the above ropes 1) to 4) are shown in the following table: dry elongation wet expansion % % Rope 1) (according to the invention) 2.4 4.4 Rope 2) 1.8 3.5 Rope 3) 1.9 3.5 Rope 4) 2.8 4.5

Daten zur Lebensdauer und Abrasionsbeständigkeit:Durability and abrasion resistance data:

Maß für die Lebensdauer ist die Rest-Bruchlast in [%] nach einem simulierten Lauf in einer nassen Sektion einer Papiermaschine. Dazu wurde eine Testeinheit entwickelt, die aus 10 Rollen besteht. Das Seil läuft mit 800m/min um und wird dabei mit Wasser besprüht (Verbrauch: 1,6 l/h). Das Seil wird unter 30kg Spannung betrieben, und um einen zusätzlichen Abriebeffekt zu erzielen, sind einige Seilrollen nicht fluchtend ausgerichtet - d.h. das Seil läuft etwas über die Seilrollenflanke ab.The measure of the service life is the residual breaking load in [%] after a simulated run in a wet section of a paper machine. For this purpose, a test unit has been developed that consists of 10 rollers. The rope runs at 800m / min and is sprayed with water (consumption: 1.6 l / h). The rope is operated under 30kg tension, and to obtain an additional abrasion effect, some pulleys are not aligned - i. the rope runs slightly over the pulley flank.

Die Restfestigkeit der Seile 1) bis 4) nach 24h dieses Versuches ist in der folgenden Tabelle angegeben: 24h Restfestigkeit % Seil 1) (erfindungsgemäß) 56,7 Seil 2) 24,3 Seil 3) 49,2 Seil 4) 39,5 The residual strength of the ropes 1) to 4) after 24 h of this experiment is given in the following table: 24h residual strength % Rope 1) (according to the invention) 56.7 Rope 2) 24.3 Rope 3) 49.2 Rope 4) 39.5

Es ist deutlich zu sehen, dass das erfindungsgemäße Seil eine verbesserte Restfestigkeit bei gleichzeitig zufriedenstellenden Dehnungseigenschaften aufweist. Eine optische Beurteilung des Seiles ergibt ein zufriedenstellendes Aussehen, während beispielsweise das Seil 3 deutliche Abnutzungsspuren aufweist.It can clearly be seen that the cable according to the invention has an improved residual strength with simultaneously satisfactory elongation properties. An optical assessment of the rope gives a satisfactory appearance, while, for example, the rope 3 has significant signs of wear.
