Abstract

In a single-blanket drying section (30), of a papermaking machine, the web (1) of fibres for paper or cardboard is carried through by the blanket and the drying cylinders (31-33) are only in contact with the under side of the web (1). The continuous support belt (29), moving together with the web (1), is at the upper sections of the cylinder mantle surfaces. A cutter (S), after the drying group (30), cuts the web leader. The cutter (S), in the direction (15) of web travel, is between the final powered cylinder (31) and a following powered web guide roller (24).

Description

Die Erfindung betrifft eine Ein-Filz-Trockengruppe mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The invention relates to a one-felt dryer group with the features specified in the preamble of claim 1.

Derartige Ein-Filz-Trockengruppen sind z.B. aus dem Gebrauchsmuster DE 295 10 637.9 bekannt. Zwischen oder auch vor solchen Ein-Filz-Trockengruppen ist ein sogenannter Spitzenschneider erforderlich. Er dient zu dem Zweck, von der laufenden Faserstoffbahn (Papier- oder Kartonbahn) einen Randstreifen abzutrennen. Dieser Randstreifen wird beim Einfädeln einer Faserstoffbahn zunächst allein in das nachfolgende Aggregat eingeführt. Erst nach dem erfolgreichen Einfädeln wird der Spitzenschneider in der Weise quer zur Bahnlaufrichtung verfahren, daß der ursprünglich schmale Randstreifen allmählich die volle Breite der Faserstoffbahn annimmt.Such single-felt dryer groups are e.g. known from utility model DE 295 10 637.9. A so-called tip cutter is required between or in front of such single-felt dryer groups. It serves the purpose of separating an edge strip from the running fibrous web (paper or cardboard web). When threading a fibrous web, this edge strip is first inserted into the subsequent unit alone. Only after successful threading is the tip cutter moved transversely to the web running direction in such a way that the originally narrow edge strip gradually takes on the full width of the fibrous web.

In der oben zitierten Schrift ist der Spitzenschneider - in Bahnlaufrichtung gesehen - zwischen einer Bahnleitwalze und einer nachfolgenden Ein-Filz-Trockengruppe angeordnet. Er schneidet dabei die Faserstoffbahn im sogenannten offenen Bahnzug. D.h., die Faserstoffbahn ist in dieser Situation weder von einem Walzenkörper noch von einem Stützband berührt. Diese Konstruktion hat den Nachteil, daß immer auch ein offener Bahnzug vorhanden sein muß. Ferner ist die Faserstoffbahn dabei wegen der fehlenden Stützung oft nicht gut geführt. Dieses kann zu Problemen der Bahnstabilität führen.In the document cited above, the tip cutter is arranged between a web guide roller and a subsequent single-felt dryer group, as seen in the direction of web travel. He cuts the fibrous web in the so-called open web train. In other words, the fibrous web is not touched by a roller body or a support belt in this situation. This construction has the disadvantage that there must always be an open train. Furthermore, the fibrous web is often not well guided due to the lack of support. This can lead to problems with web stability.

Ein besonderes Problem ist es, wenn die Faserstoffbahn noch nicht ausreichend trocken und damit auch noch nicht ausreichend fest ist.It is a particular problem if the fibrous web is not yet sufficiently dry and therefore not yet sufficiently strong.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ausgehend von der im Oberbegriff des Anspruches 1 angegebenen Ein-Filz-Trockengruppe, eine Variante vorzuschlagen, die ein sicheres Schneiden des Randstreifens ermöglicht.The invention is therefore based on the object, on the basis of the single-felt drying group specified in the preamble of claim 1, to propose a variant which enables safe cutting of the edge strip.

Die Aufgabe wird durch das im kennzeichnenden Teil des Anspruches 1 angegebene Merkmal gelöst. Der Spitzenschneider wurde am Ende der Ein-Filz-Trockengruppe positioniert. Durch diese Anordnung erfährt eine Faserstoffbahn zunächst erst noch eine zusätzliche Trocknung und damit auch zusätzliche Festigkeitserhöhung.The object is achieved by the feature specified in the characterizing part of claim 1. The tip cutter was positioned at the end of the single felt dryer group. With this arrangement, a fibrous web first undergoes additional drying and thus an additional increase in strength.

Mindestens der letzte Trockenzylinder der Ein-Filz-Trockengruppe wird angetrieben. Die nicht angetriebenen Zylinder werden dann über das Stützband mitgezogen. Wäre ein anderer, oder wären andere Zylinder angetrieben, so könnte - bedingt durch Schlupf - sich zum letzten Zylinder hin eine nur unsicher abschätzbare Differenz-Umfangsgeschwindigkeit ergeben. Aus diesem Grunde wäre die tatsächliche Bahngeschwindigkeit nach dem letzten Zylinder nicht exakt definiert.At least the last drying cylinder of the single felt dryer group is driven. The non-driven cylinders are then pulled along with the support belt. If another cylinder were to be driven, or due to slippage, a differential circumferential speed that could only be estimated with uncertainty could result towards the last cylinder. For this reason, the actual path speed after the last cylinder would not be exactly defined.

Wird die dem letzten Zylinder nachfolgend angeordnete Bahnleitwalze ebenfalls angetrieben, so ist mit Hilfe der definierten Umfangsgeschwindigkeiten von Zylinder und Bahnleitwalze der Aufbau von einem spezifischen Bahnzug in der Faserstoffbahn möglich.If the web guide roller arranged downstream of the last cylinder is also driven, it is possible to build up a specific web tension in the fibrous web with the aid of the defined peripheral speeds of the cylinder and web guide roller.

Die oben beschriebene Position des Spitzenschneiders kann aber noch weiter optimiert werden. Am letzten Zylinder - in Bahnlaufrichtung gesehen - wird erst das Stützband und dann erst die Faserstoffbahn von der Zylinderoberfläche abgehoben. So erfährt die Faserstoffbahn noch eine Stützung durch die Zylindermantelfläche. Wird in diesem Bereich geschnitten, so kann die Faserstoffbahn nicht dem Schneiddruck ausweichen und führt zu einem beherrschbareren Schneiden des Randstreifens. Die Schneideinrichtung müßte in diesem Fall ein Wasserstrahl-Spitzenschneider sein, damit die Zylinderoberfläche nicht verletzt wird.However, the position of the tip cutter described above can be further optimized. On the last cylinder - seen in the direction of web travel - first the support belt and then the fibrous web is lifted off the cylinder surface. In this way, the fibrous web is supported by the surface of the cylinder. When cutting in this area, the fibrous web cannot avoid the cutting pressure and leads to a more manageable cutting of the edge strip. In this case, the cutting device would have to be a water jet tip cutter so that the cylinder surface is not damaged.

Die Erfindung soll anhand der Figur 1 näher erläutert werden.The invention will be explained in more detail with reference to FIG. 1.

Eine Faserstoffbahn 1 wird von einer Bahnbehandlungseinrichtung kommend (z.B. Streichstation oder Leimpresse) über eine Breitstreckwalze 20 um den Trockenzylinder 34 herum der Ein-Filz-Trockengruppe 30 zugeführt. Weil der Trockenzylinder 34 nicht von dem Stützband 29 umschlungen wird, hat er einen separaten Antrieb 24. Beim Durchlaufen der Faserstoffbahn 1 durch die Ein-Filz-Trockengruppe 30 in Bahnlaufrichtung 15 werden die Zylinder 33, 32 und 31 an ihren oberen Bereichen der Manteloberfläche von der Bahn 1 nacheinander umschlungen. Zwischen den ebenfalls auch vom Stützband 29 umschlungenen Zylindern 33, 32 und 31 befinden sich Umlenkwalzen 27 mit Bahnstabilisatoren 26. Diese Umlenkwalzen 27 sind Saugwalzen und können gelochte, gerillte oder gelochte und gerillte Walzen sein. Über den Bahnstabilisator 26 werden die Saugwalzen 27 und die Taschen zwischen den Zylindern 33, 32, 31 und den Saugwalzen 27 besaugt.A fibrous web 1 is coming from a web treatment device (for example a coating station or size press) via a Spreader roll 20 is fed around drying cylinder 34 to single-felt dryer group 30. Because the drying cylinder 34 is not wrapped around by the support belt 29, it has a separate drive 24. When the fibrous web 1 passes through the single-felt drying group 30 in the web running direction 15, the cylinders 33, 32 and 31 on their upper regions of the outer surface of the web 1 looped one after the other. Deflection rollers 27 with web stabilizers 26 are located between the cylinders 33, 32 and 31, which are also wrapped by the support belt 29. These deflection rollers 27 are suction rollers and can be perforated, grooved or perforated and grooved rollers. The suction rolls 27 and the pockets between the cylinders 33, 32, 31 and the suction rolls 27 are sucked in via the web stabilizer 26.

Am Ende der Ein-Filz-Trockengruppe 30 wird das Stützband 29 an der Leitwalze 25 derart umgelenkt, daß die auf dem Zylinder 31 aufliegende Faserstoffbahn 1 an ihrer Oberseite freigegeben wird. Die nachfolgende Bahnleitwalze 21 ist optional mit einem separatem Antrieb 24 versehen. Zwischen dem Zylinder 31 und der Bahnleitwalze 21 läßt sich so exakt ein Bahnzug in der Faserstoffbahn 1 aufbauen. In diesem Bereich, wo die Faserstoffbahn 1 noch auf dem Zylinder 31 aufliegt, ist sie besonders gut gestützt. Hier ist vorteilhafterweise der mit einem Pfeil gekennzeichnete Wasserstrahl-Spitzenschneider S angeordnet.At the end of the single-felt drying group 30, the support belt 29 is deflected on the guide roller 25 in such a way that the fibrous web 1 resting on the cylinder 31 is released on its upper side. The subsequent web guide roller 21 is optionally provided with a separate drive 24. A web tension in the fibrous web 1 can thus be built up exactly between the cylinder 31 and the web guide roller 21. In this area, where the fibrous web 1 still rests on the cylinder 31, it is particularly well supported. The water jet tip cutter S, which is marked with an arrow, is advantageously arranged here.

Wenn die Faserstoffbahn 1 in die Ein-Filz-Trockengruppe 30 eingefädelt wurde, so läuft sie zunächst am Zylinder 21 als Ausschußbahn 1 nach unten in den nicht dargestellten Ausschußpulper ab. Um ein Anhaften am Zylinder 21 zu vermeiden, ist ein Schaber 14 auf die Zylinderoberfläche aufgesetzt. Der Spitzenschneider S trennt dann die Faserstoffbahn bei einem Randabstand von etwa 200-500 mm in zwei Einzelstreifen. Durch ebenfalls nicht dargestellte Blaselemente wird dann der schmalere Bahnstreifen - der sogn. Bändel - um die Bahnleitwalze 21 herum zu weiteren Elementen der Papiermaschine gelenkt. Durch den antreibbaren Zylinder 21 und die ebenfalls antreibbare Bahnleitwalze 21 kann nun ein definierter Zug in der Faserstoffbahn 1 aufgebaut werden, der den Trennvorgang stabilisiert. Nach erfolgreicher Überführung der Faserstoffbahn 1 zu weiteren Elementen der Papiermaschine wird der Spitzenschneider quer zur Bahnlaufrichtung in Richtung zum breiteren Streifen verfahren, so daß der Bändel selbst breiter wird. Hat der Bändel so die volle Breite der Faserstoffbahn 1 erreicht, so ist die Überführung der Faserstoffbahn 1 abgeschlossen und der Spitzenschneider S kann abgeschaltet werden.When the fibrous web 1 has been threaded into the single-felt dryer group 30, it first runs downward on the cylinder 21 as the reject web 1 into the reject pulper (not shown). In order to avoid sticking to the cylinder 21, a scraper 14 is placed on the cylinder surface. The tip cutter S then separates the fibrous web into two individual strips at an edge distance of approximately 200-500 mm. Blower elements, also not shown, then make the narrower web strip - the so-called. Ribbon - directed around the web guide roller 21 to further elements of the paper machine. Through the drivable cylinder 21 and the web guide roller 21, which can also be driven, can now build up a defined train in the fibrous web 1, which stabilizes the separation process. After successful transfer of the fibrous web 1 to other elements of the paper machine, the tip cutter is moved transversely to the direction of web travel in the direction of the wider strip, so that the ribbon itself becomes wider. When the ribbon has reached the full width of the fibrous web 1, the transfer of the fibrous web 1 is complete and the tip cutter S can be switched off.
