Description

Die Erfindung betrifft ein Spiralgliederband mit einer Vielzahl von mit einander Kämmenden Kunststoffdrahtwendeln gemaß Oberbegriff des Anspruchs 1.The invention relates to a spiral link belt with a plurality of intermeshing plastic wire coils in accordance with the preamble of claim 1.

Derartige Spiralgliederbänder sind bekannt (DE-A-2419751 und 29 38 221 und EP-A-0018200) und werden unter anderem in der Trockenpartie von Papiermaschinen als Bespannungen eingesetzt. Vor dem Erreichen der Trockenpartie ist der Blattbildungsprozess der Papierbahn weitgehend abgeschlossen und die Papierbahn derart verdichtet, daß sie nicht mehr sehr markierungsanfällig ist. Wegen der Markierungsgefahr war ein Einsatz der Spiralgliederbänder im Blattbildungsteil einer Papiermaschine bisher nicht möglich.Such spiral link belts are known (DE-A-2419751 and 29 38 221 and EP-A-0018200) and are used, among other things, as clothing in the dryer section of paper machines. Before reaching the dryer section, the sheet formation process of the paper web is largely completed and the paper web is compacted in such a way that it is no longer very susceptible to marking. Due to the risk of marking, it was previously not possible to use the spiral link belts in the sheet forming part of a paper machine.

Ein weiterer Nachteil besteht darin, daß wegen der sehr großen Hohlräume im Inneren der Spiralgliederbänder große Luftmengen mittransportiert werden, so dass die Spiralgliederbänder bei hohen Geschwindigkeiten der Papiermaschine als Luftgebläse wirken, wobei an den Umlenkstellen der Bandführung die mitgeführte Luft herausgeschleudert wird, wodurch die Papierbahn zu flattern beginnt und bei höheren Geschwindigkeiten sogar reissen kann. Man hat versucht, dieses Problem dadurch zu lösen, dass die in den Spiralgliederbändern vorhandenen Hohlräume so weit wie möglich durch voluminöse Garne und dergleichen ausgefüllt wurden. Das Markierungsproblem beim Einsatz im Blattbildungsteil einer Papiermaschine blieb jedoch bestehen.Another disadvantage is that because of the very large cavities inside the spiral link belts, large amounts of air are also transported, so that the spiral link belts act as air blowers at high speeds of the paper machine, the entrained air being thrown out at the deflection points of the belt guide, causing the paper web to close begins to flutter and can even tear at higher speeds. Attempts have been made to solve this problem by filling the voids in the spiral link belts as far as possible with voluminous yarns and the like. However, the marking problem when used in the sheet forming part of a paper machine remained.

Wegen der gröberen Oberflächenstruktur ist ausserdem die Retention der Papierfasern unzureichend.Due to the coarser surface structure, the retention of the paper fibers is also insufficient.

Aufgabe der Erfindung ist daher die Schaffung eines Spiralgliederbandes, das auch zum Einsatz im Blattbildungsteil einer Papiermaschine geeignet ist.The object of the invention is therefore to provide a spiral link belt which is also suitable for use in the sheet-forming part of a paper machine.

Diese Aufgabe wird durch die Merkmale des Kennzeichens des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Gegenstand der Erfindung ist ferner ein Verfahren zur Herstellung des erfindungsgemässen Spiralgliederbandes.The invention further relates to a method for producing the spiral link belt according to the invention.

Die Verbindung zwischen dem Spiralgliederband und dem Gewebe kann auf verschiedene Weise durchgeführt werden. Vorzugsweise werden in das Gewebe in bestimmten Abständen auf der Unterseite Verbindungsschlaufen eingewoben. Diese Verbindungsschlaufen können sowohl aus den strukturellen Webdrähten des Gewebes gebildet werden als auch durch einen Draht, der an der Gestaltung der Gewebestruktur nicht beteiligt ist. Dieser Draht kann in Kett- oder in Schussrichtung verlaufen.The connection between the spiral link band and the tissue can be carried out in various ways. Connection loops are preferably woven into the fabric at certain intervals on the underside. These connecting loops can be formed both from the structural weave wires of the fabric and by a wire that is not involved in the design of the fabric structure. This wire can run in the warp or weft direction.

Die richtige Form und Grösse der Verbindungsschlaufen kann durch das Einweben von Behelfsdrähten bestimmter Stärke erreicht werden. Werden die Verbindungsschlaufen aus Kettdrähten gebildet (aus struktureller Kette oder zusätzlicher Bindekette), so werden in bestimmtem Rhythmus zusätzliche Behelfsschussdrähte durchgezogen. Diese Behelfsschussdrähte werden lediglich durch die zur Herstellung der Verbindungsschlaufen bestimmten Kettdrähte umschlungen und bleiben somit auf einer Siebseite außerhalb der Gewebestruktur liegen.The correct shape and size of the connecting loops can be achieved by weaving in auxiliary wires of a certain thickness. If the connecting loops are made from warp wires (from a structural chain or additional binding chain), additional auxiliary weft wires are pulled through at a certain rhythm. These auxiliary weft wires are only wrapped around the warp wires intended for the production of the connecting loops and thus remain on one side of the screen outside of the fabric structure.

In ähnlicher Weise wird bei der Bildung der Verbindungsschlaufen aus dem Schussdraht vorgegangen, nur dass jetzt die Behelfsdrähte in bestimmten Abständen in Kettrichtung verlaufen und durch eigene, gesonderte Litzenrahmen betätigt werden. Sie werden ausserhalb des Gewebes gehalten und erst an der Verbindungsstelle durch den strukturellen oder zusätzlichen Bindeschussdraht eingebunden. Vor dem Zusammenfügen des Gewebes und des Spiralgliederbandes werden die Behelfsdrähte herausgezogen, aufgelöst oder in sonstiger Weise entfernt. Die Verbindungsschlaufen des Gewebes werden zwischen den Spiralwindungen eingelassen und beide Lagen, d. h. das Spiralgliederband und das Gewebe, werden durch das Einführen von Steckdrähten miteinander verbunden.A similar procedure is used to form the connecting loops from the weft wire, only that the auxiliary wires now run at certain intervals in the warp direction and are operated by their own, separate stranded wire frames. They are held outside the fabric and only integrated at the junction by the structural or additional binding weft wire. Before the fabric and the spiral link band are joined together, the auxiliary wires are pulled out, dissolved or otherwise removed. The connecting loops of the fabric are inserted between the spiral turns and both layers, i.e. H. the spiral link band and the tissue are connected to each other by inserting plug wires.

Besonders vorteilhaft ist es, als Material für die Verbindungsschlaufen stark schrumpfendes Drahtmaterial zu verwenden. Der Thermoschrumpf dieser Drähte soll vorzugsweise höher sein als bei den Kett- und Schussdrähten des Gewebes und des Spiralgliederbandes. Beim abschliessenden Thermofixieren werden durch den hohen Schrumpf der Verbindungsschlaufen die Steckdrähte stramm festgehalten.It is particularly advantageous to use strongly shrinking wire material as the material for the connecting loops. The thermal shrinkage of these wires should preferably be higher than that of the warp and weft wires of the fabric and the spiral link belt. During the final heat setting, the plug wires are held tight by the high shrinkage of the connecting loops.

Das Material der Steckdrähte kann vom Material des Gewebes und dem der Wendeln oder Spiralen des Gliederbandes abweichen. Vorzugsweise bestehen die Steckdrähte aus einem Material mit einer wesentlich niedrigeren Schmelztemperatur als das Material des Gewebes oder das der Wendeln, z. B. Polyamid oder Polypropylen. Bei der Herstellung des Spiralgliederbandes werden die eingeschobenen Steckdrähte so zugeschnitten, dass sie an der Rändern einige Zentimeter hervorstehen. Nach der Endausrüstung des Siebes werden die vorstehenden Enden der Steckdrähte mittels Wärme oder Ultraschall verschmolzen. Dadurch entsteht eine gute Führungskante an beiden Rändern des Spiralgliederbandes. Eine Versprödung der Wendeln oder des Gewebes findet wegen deren höheren Schmelztemperatur nicht statt. Bei Ultraschallverschweissung findet ein Verschmelzen zwischen den Spiralwendeln aus Polyester und dem verschmolzenen Polyamid- oder Polypropylen-Material der Steckdrähte nicht statt. Das verschmolzene, fremdartige Material der Steckdrähte füllt lediglich die Hohlräume an der Kante des Spiralbandes aus. Diese Art der Herstellung von Führungskanten an Spiralgliederbändern ist auch auf die herkömmlichen Spiralgliederbänder anwendbar. Statt der Steckdrähte kann dabei gegebenenfalls auch das Füllmaterial eine niedrigere Schmelztemperatur aufweisen und an den seitlich herausstehenden Enden zur Bildung von Führungskanten verschmolzen werden.The material of the plug wires can differ from the material of the fabric and that of the spirals or spirals of the link belt. Preferably, the plug wires are made of a material with a significantly lower melting temperature than the material of the fabric or that of the coils, e.g. B. polyamide or polypropylene. When manufacturing the spiral link belt, the inserted plug wires are cut so that they protrude a few centimeters at the edges. After finishing the sieve, the protruding ends of the plug wires are fused using heat or ultrasound. This creates a good leading edge on both edges of the spiral link belt. Embrittlement or the tissue does not become brittle because of their higher melting temperature. With ultrasonic welding, there is no fusion between the spiral spirals made of polyester and the fused polyamide or polypropylene material of the plug wires. The fused, strange material of the plug wires only fills the cavities on the edge of the spiral tape. This type of production of guide edges on spiral link belts is also applicable to the conventional spiral link belts. Instead of the plug-in wires, the filler material can optionally also be low have lower melting temperature and are fused at the laterally protruding ends to form leading edges.

Die Ränder des fertigen, mit einem Gewebe bedeckten Spiralgliederbandes können nach Bedarf in bekannter Weise mit Klebstoffen getränkt werden, um zu verhindern, dass sich nach längerem Gebrauch die einzelnen Längsfäden aus der Kante lösen.The edges of the finished spiral-link belt, which is covered with a fabric, can be impregnated with adhesives in a known manner as required, in order to prevent the individual longitudinal threads from coming off the edge after prolonged use.

Das Spiralgliederband und das Gewebe könner. auch durch Verkleben oder Ultraschallschweissung stellenweise oder flächenhaft miteinander verbunden werden. Es ist auch möglich, ein Gewebe sowohl durch Verbindungsösen als auch durch Kleben oder Schweissen mit dem Spiralgliederband zu verbinden.The spiral link belt and the fabric can. also by gluing or ultrasound welding in places or areas. It is also possible to connect a fabric to the spiral link belt by means of connecting eyes as well as by gluing or welding.

Das das Spiralgliederband bedeckende Gewebe kann in üblicher Weise endlos gemacht werden, z. B. durch eine Webnaht. Das Gewebe wird dabei vorzugsweise vor dem Spiralgliederband durch eine Webnaht endlos gemacht oder das Spiralgliederband wird zum Endlosmachen des Gewebes durch Herausziehen eines Steckdrahtes geöffnet, um die Herstellung der Webnaht zu erleichtern. Nach Fertigstellung der Webnaht werden die Spiralen durch Einschieben des Steckdrahtes wieder verbunden. Da im Einsatz des gewebebedeckten Spiralgliederbandes die durch Steckdrähte verbundenen Spiralen die Zugkräfte aufnehmen, kann die Webnaht sehr schmal ausgeführt werden.The fabric covering the spiral link belt can be made endless in a conventional manner, e.g. B. by a woven seam. The fabric is preferably made endless in front of the spiral link belt by a woven seam, or the spiral link belt is opened to make the fabric endless by pulling out a plug wire in order to facilitate the production of the woven seam. After completion of the woven seam, the spirals are connected again by inserting the plug wire. Since the spirals connected by plug-in wires absorb the tensile forces when using the fabric-covered spiral link belt, the woven seam can be made very narrow.

Die Vorteile des erfindungsgemässen gewebebedeckten Spiralgliederbandes bestehen insbesondere darin, dass für das Gewebe eine sehr feine Struktur gewählt werden kann und damit die gewünschte Markierungsfreiheit, die gute Retention der Papierfasern und die erforderliche Durchlässigkeit verwirklicht werden können. Die Spiralen können zur Erreichung einer Verschleissfestigkeit und einer hohen Längsstabilität aus relativ groben Kunststoffdrähten bestehen.The advantages of the fabric-covered spiral link belt according to the invention are, in particular, that a very fine structure can be selected for the fabric and thus the desired freedom of marking, the good retention of the paper fibers and the required permeability can be achieved. To achieve wear resistance and high longitudinal stability, the spirals can consist of relatively coarse plastic wires.

Das erfindungsgemässe gewebebedeckte Spiralgliederband kann sowohl im Blattbildungsteil der Papiermaschine, also als Papiermaschinensieb eingesetzt werden, als auch als Trockensieb bei besonders markierungsempfindlichen Papiersorten. Daneben kann es auch als Transportband oder Filtermedium eingesetzt werden, immer dann, wenn ein stabiles Band mit guten Entwässerungseigenschaften und gleichzeitig glatter Oberfläche und hoher Retention erforderlich ist.The fabric-covered spiral link belt according to the invention can be used both in the sheet-forming part of the paper machine, that is to say as a paper machine screen, and as a drying screen for particularly sensitive paper types. It can also be used as a conveyor belt or filter medium whenever a stable belt with good drainage properties and at the same time a smooth surface and high retention is required.

Das Gewebe kann aus Monofilen oder aus multifilen Kunststoffäden gewoben sein. Es kann durch Benadeln zusätzlich mit einem Faserflor versehen werden, wodurch auch der Einsatz in Entwässerungspressen oder in den ersten Gruppen der Trockenpartei bei der Herstellung feinster Papiere ermöglicht wird.The fabric can be woven from monofilament or from multifilament plastic threads. It can also be provided with a fibrous web by needling, which also enables use in dewatering presses or in the first groups of the drying party in the production of the finest papers.

Das Gewebe 4 kann somit dadurch mit dem Spiralgliederband 1 verbunden werden, das Verbindungsdrähte 8 durch den Hohlraum der Spiralen 2 und die in diesen Hohlraum hineinragenden Verbindungsschlaufen 7 des Gewebes 4 geschoben werden.The connecting loops 7 are so long that they penetrate into the interior of the spirals 2 when the fabric 4 is placed on a spiral link belt 1. The fabric 4 can thus be connected to the spiral link belt 1, the connecting wires 8 are pushed through the cavity of the spirals 2 and the connecting loops 7 of the fabric 4 protruding into this cavity.

Fig. 2 zeigt einen Schnitt ähnlich dem der Fig. 1. Die Verbindungsschlaufen 7 werden in Fig. 2 von einer speziellen Bindekette 6 gebildet. Aus Gründen der Übersichtlichkeit ist der Verlauf der sich daran anschließenden Kettdrähte 9 in Fig. 2 getrennt dargestellt. Die Bindekette 6 ist über die beiden Schussdrähte 5 unmittelbar vor und nach einer Verbindungsschlaufe geführt und verläuft ansonsten unter den Schussdrähten 5. Die Bindekette 6, die die Verbindungsschlaufen 7 bildet, kann bereits bei der Herstellung des Gewebes 4 eingewoben werden oder kann nachträglich in das Gewebe eingezogen werden. Die strukturellen Kettdrähte 9 und die Schussdrähte 5 bilden wiederum eine Leinwandbindung. Es ist jedoch auch jede andere Bindung möglich.FIG. 2 shows a section similar to that of FIG. 1. The connecting loops 7 are formed in FIG. 2 by a special binding chain 6. For the sake of clarity, the course of the adjoining warp wires 9 is shown separately in FIG. 2. The binding chain 6 is guided over the two weft wires 5 immediately before and after a connecting loop and otherwise runs under the weft wires 5 bes 4 can be woven in or can be pulled into the fabric afterwards. The structural warp wires 9 and the weft wires 5 in turn form a plain weave. However, any other binding is also possible.

Bei der in Fig. 3 dargestellten Ausführungsform besitzt das Gewebe 4 eine doppellagige Bindung, d. h. die Schussdrähte 5 sind in zwei Lagen angeordnet, und zumindest ein Teil der Kettdrähte 9 ist mit beiden Lagen verwoben. Ebenso sind die Bindeketten 6 mit beiden Lagen verwoben. Durch die Verwendung eines doppellagigen Gewebes 4 ergibt sich eine weitere Verbesserung der Retention und Markierungsfreiheit der Papiermaschinenbespannung, so dass diese auch im Papierbildungsbereich der Papiermaschine zur Herstellung feinster Papiere eingesetzt werden kann.In the embodiment shown in Fig. 3, the fabric 4 has a double-layer weave, i.e. H. the weft wires 5 are arranged in two layers, and at least some of the warp wires 9 are interwoven with both layers. Likewise, the binding chains 6 are interwoven with both layers. The use of a double-layer fabric 4 results in a further improvement in the retention and freedom of marking of the paper machine clothing, so that it can also be used in the paper formation area of the paper machine for producing the finest papers.

BeispieleExamples

Es soll ein Spiralgliederband ähnlich dem von Fig. 2 herstellt werden.A spiral link belt similar to that of FIG. 2 is to be produced.

Das Spiralgliederband wird aus monofilen Polyester-Drähten hergestellt. Die Spiralen haben sieben Windungen per cm und sind aus einem monofilen Polyester-Draht von 0,70 mm Durchmesser hergestellt. Die Steckdrähte aus Polyester-Monofil sind 0,90 mm stark und liegen in Abständen von 5 mm voneinander.The spiral link belt is made from monofilament polyester wires. The spirals have seven turns per cm and are made of a monofilament polyester wire with a diameter of 0.70 mm. The plug wires made of polyester monofilament are 0.90 mm thick and are spaced 5 mm apart.

Das Spiralgliederband hat eine Dicke von 2,50 mm und eine Luftdurchlässigkeit von 970 cfm.The spiral link belt has a thickness of 2.50 mm and an air permeability of 970 cfm.

Das Gewebe besitzt Leinwandbindung. Die Kettzahl beträgt 28 Drähte/cm. Die Kette ist 0,17 mm stark und ist aus Polyester-Monofil mit einem Thermoschrumpf von 11,5 % bei 200 °C.The fabric has a plain weave. The warp number is 28 wires / cm. The chain is 0.17 mm thick and is made of polyester monofilament with a thermal shrinkage of 11.5% at 200 ° C.

Die Schussdrahtzahl beträgt ebenfalls 28 Drähte/cm. Die Schussdrähte sind aus Polyester-Monofil, Durchmesser 0,18 mm, und haben einen Thermoschrumpf von 2,2 %. Die Luftdurchlässigkeit des Obersiebes ist 416 cfm, die Luftdurchlässigkeit beider Gewebelagen zusammen ist 403 cfm.The number of weft wires is also 28 wires / cm. The weft wires are made of polyester monofilament, diameter 0.18 mm, and have a thermal shrinkage of 2.2%. The air permeability of the top wire is 416 cfm, the air permeability of both fabric layers together is 403 cfm.

Der Bindekettdraht ist ein Polyester-Monofil, Durchmesser 0,17 mm, und hat einen Thermoschrumpf von 24,5 %.The binding warp wire is a polyester monofilament, diameter 0.17 mm, and has a thermal shrinkage of 24.5%.

Er verläuft nach jedem 14. Kettdraht und bildet die Verbindungsschlaufen nach jedem 28. Schussdraht.It runs after every 14th warp wire and forms the connection loops after every 28th weft wire.

Die Verbindungsdrähte zwischen dem Gewebe und dem Spiralgliederband bestehen aus Polyester-Monofil.The connecting wires between the fabric and the spiral link belt are made of polyester monofilament.

In einem weiteren, ansonsten identischen Beispiel bestehen die monofilen Verbindungsdrähte aus Polyamid oder Polypropylen, mit niedrigerem Schmelzpunkt (130-210 °C) als bei den Polyesterdrähten (254 °C), damit ein Verschweißen der Siebränder möglich ist. Bei der Verschweißung der Kanten mit einem Ultraschallgerät wird dann nur der Polyamid- bzw. Polypropylendraht verschmolzen und bildet die notwendige Verklebung am Siebrand, ohne daß die Drähte des Gewebes und die Spiralen des Spiralgliederbandes durch das Schmelzen betroffen werden.In another, otherwise identical example, the monofilament connecting wires are made of polyamide or polypropylene, with a lower melting point (130-210 ° C) than for the polyester wires (254 ° C), so that the screen edges can be welded together. When the edges are welded with an ultrasound device, only the polyamide or polypropylene wire is then fused and forms the necessary bond on the screen edge, without the wires of the fabric and the spirals of the spiral link belt being affected by the melting.
