Description

Die Erfindung betrifft einen Rollenschneider mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a slitter with the Features of the preamble of claim 1.

Ein derartiger Rollenschneider ist aus DE 30 40 189 A1 bekannt. Er dient zum Schneiden und Aufwickeln von Filmstreifen.Such a winder is from DE 30 40 189 A1 known. It is used for cutting and winding up Filmstrip.

Die Erfindung soll im folgenden anhand einer Papierbahn als Beispiel für eine Materialbahn beschrieben werden. Sie ist darauf jedoch nicht beschränkt.The invention is intended to be based on a paper web can be described as an example of a material web. However, it is not limited to this.

In einem der letzten Herstellungsschritte muß die Papierbahn auf eine Breite geschnitten werden, die für einen späteren Verarbeiter, beispielsweise einen Drukker, handhabbar ist. Da Papierbahnen heute durchaus Breiten im Bereich von 8 bis 10 m aufweisen können, die von den Verbrauchern gewünschten Breiten aber im Bereich von 0,8 m bis 3,8 m liegen, schneidet man üblicherweise aus einer Papierbahn mehrere Teilbahnen im gewünschten Breitenbereich. Diese Teilbahnen werden dann zu Teilbahnrollen aufgewickelt. Wenn es beim Wikkeln notwendig ist, die Stirnseiten der Teilbahnrollen frei zugänglich zu halten, beispielsweise bei einer Unterstützung des Rollenkerns durch Tragarme, dann müssen die Wickelpositionen quer zur Wickelachse versetzt zueinander angeordnet sein. Dadurch kann man die einzelnen Teilbahnrollen axial mit Abstand zueinander anordnen. Alle Wickelpositionen, in denen mit axialem Abstand Teilbahnrollen angeordnet sind, bilden zusammen eine Wickelpositionsgruppe. Die Teilbahnrollen unterschiedlicher Wickelpositionsgruppen sind dann auf Lücke zueinander angeordnet.In one of the last manufacturing steps, the paper web to be cut to a width suitable for a later processor, for example a printer, is manageable. Because paper webs today May have widths in the range of 8 to 10 m widths desired by consumers but in the range from 0.8 m to 3.8 m are usually cut from a paper web several partial webs in desired width range. These partial webs will be then wound up into partial web rolls. If it is winding is necessary, the end faces of the partial web rolls to keep it freely accessible, for example with support of the roll core through support arms, then must the winding positions offset to one another transversely to the winding axis be arranged. This way you can see the individual Arrange partial web rollers axially at a distance from each other. All winding positions in which with an axial distance Partial web rolls are arranged together a winding position group. The partial web roles different Then winding position groups are on gap arranged to each other.

Zum Aufwickeln der Teilbahnrollen müssen gewisse Vorbereitungen getroffen werden. In der Regel muß ein vorbereiteter Rollenkern in die Wickelposition eingelegt werden. In den dafür benötigten Rüstzeiten kann nicht gewickelt werden, so daß das Wickeln der Teilbahnrollen unterbrochen werden muß. Die Effektivität des Rollenschneiders wird hierdurch verschlechtert, weil man zwischen den einzelnen Wickelvorgängen Pausen einlegen muß, die sich deutlich bemerkbar machen.Certain preparations are required to wind up the partial web rolls to be hit. As a rule, a prepared one Roll core inserted in the winding position become. In the set-up times required for this, be wound so that the winding of the partial web rolls must be interrupted. The effectiveness of the winder is worsened because you are between take breaks during the individual wrapping processes must make themselves clearly noticeable.

Der Erfindung liegt die Aufgabe zugrunde, die Effektivität eines Rollenschneiders zu steigern.The invention is based, the effectiveness a slitter winder.

Diese Aufgabe wird bei einem Rollenschneider der eingangs genannten Art durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This task is the beginning of a slitter mentioned type by the characteristics of the characteristic Part of claim 1 solved.

Unter "Aufwickeln" soll hierbei nur der Vorgang verstanden werden, bei dem die Teilbahnrolle gedreht wird, um die Teilbahnrolle aufzunehmen. Übergänge von einer Teilbahnrolle zur anderen, genauer gesagt, zu einem neuen Rollenkern oder Rollenzentrum, gehören in diesem Sinne nicht zum Aufwickeln. Dadurch, daß man mehr Wikkelpositionsgruppen bereit stellt, als an und für sich notwendig sind, kann man die freie(n) Wickelpositionsgruppe(n) dazu verwenden, die für das Aufwickeln der Teilbahnrollen notwendigen Vorbereitungen zu treffen, beispielsweise vorbereitete Rollenkerne in die einzelne(n) Wickelposition(en) einlegen. Dadurch, daß im Wikkelabschnitt mindestens eine Wickelpositionsgruppe mehr, aber weniger als das Doppelte der Wickelpositionsgruppen, die zum Aufwickeln der Teilbahnrollen notwendig sind, vorgesehen sind, spart man mindestens eine Wickelpositionsgruppe ein, denn es sollen weniger als das Doppelte der zum Aufwickeln der Teilbahnrollen notwendigen Wickelpositionsgruppen vorgesehen sein. In der Regel reicht es sogar aus, wenn nur eine Wickelpositionsgruppe mehr vorgesehen ist. Damit läßt sich ein quasi kontinuierliches Wickeln realisieren. Die Rüstzeiten entfallen zumindest weitgehend."Winding up" is understood to mean only the process in which the partial web roll is rotated, to take up the partial web roll. Transitions from one Partial web roll to another, more precisely, to one new role core or role center belong in this Senses not to wind up. By having more winding position groups provides, as in and for itself necessary, the free winding position group (s) can be use the for winding the Make necessary preparations for partial web rolls, For example, prepared roll cores into the individual (s) Insert wrapping position (s). Because in the winding section at least one winding position group more, but less than double the winding position groups, necessary for winding the partial web rolls are provided, you save at least one Winding position group, because there should be less than double that required to wind up the partial web rolls Winding position groups can be provided. In the As a rule, it is even sufficient if only one winding position group more is provided. It can be quasi realize continuous winding. The setup times are at least largely eliminated.

Man hält zwar nicht mehr für jede Wickelposition eine Ersatzposition bereit. Dies ist aber dann nicht notwendig, wenn man einerseits dafür sorgt, daß jede Teilbahn zu jeder Wickelpositionsgruppe geführt werden kann, und man andererseits dafür sorgt, daß der Wechsel von einer vollen Teilbahnrolle zu einer neuen Teilbahnrolle erfolgt, während die anderen Teilbahnrollen weitergewickelt werden. Mit anderen Worten: nicht alle Teilbahnrollen werden gleichzeitig fertig, so daß es nicht notwendig ist, den Rollenwechsel für alle Teilbahnrollen gleichzeitig durchzuführen. Eine derartige Vorgehensweise beim Erzeugen von Teilbahnrollen läßt sich ohne Probleme immer dann realisieren, wenn die Materialbahn kontinuierlich zugeführt werden kann. Anstelle der kontinuierlichen Zufuhr kann man auch eine Materialbahn zuführen, deren Länge größer ist als die Länge der auf einzelne Teilbahnrollen aufzuwickelnden Materialbahn. Dies ist in der Regel dann der Fall, wenn die Materialbahn von sogenannten Jumborollen abgewickelt wird.One no longer holds one for every winding position Replacement position ready. But this is not necessary if, on the one hand, you make sure that every partial web can be led to each winding position group, and on the other hand, it is ensured that the change from one full Partial web roll to a new partial web roll, while the other partial web rolls are being wound. In other words: not all partial web roles will be finished at the same time so that it is not necessary the roll change for all partial web rolls at the same time perform. Such an approach to creation of partial web rolls can always be done without problems then realize if the material web is continuous can be supplied. Instead of continuous You can also feed a web of material whose Length is greater than the length of the individual partial web rolls material web to be wound. This is in usually the case when the material web of so-called Jumbo rolls is unwound.

Vorzugsweise sind drei Wickelpositionsgruppen vorhanden. Dies ist sozusagen die Minimalausstattung. Das Wickeln erfolgt dann beispielsweise dadurch, daß Teilbahnrollen in den Wickelpositionsgruppen I und II gewickelt werden. Die Wickelpositionsgruppe III ist frei und kann für die Vorbereitung der Rollenkerne genutzt werden. Wenn die Teilbahnrollen in der Wickelposition II fertig sind, kann eine Überleitung auf die Rollenkerne in der Wickelposition III erfolgen. Die Wickelposition II ist dann frei, so daß hier die entsprechenden Vorbereitungen getroffen werden können und die Teilbahnen danach von der Wickelpositionsgruppe I auf die Wikkelpositionsgruppe II übergeleitet werden. Wenn dann die Teilbahnrollen in der Wickelpositionsgruppe III fertig sind, können diese auf die Wickelpositionsgruppe I übergeleitet werden. In allen Fällen ist es möglich, die einzelnen Teilbahnrollen in den Wickelpositionsgruppen mit axialem Abstand zueinander zu halten. Dennoch ist immer eine Wickelpositionsgruppe frei, in der man die notwendigen Vorbereitungen für das Aufwickeln treffen kann. Eine Unterbrechung des Betriebs ist praktisch nicht oder allenfalls nur ganz kurz erforderlich, um die einzelnen Teilbahnen von einer Wickelpositionsgruppe in eine andere überzuleiten.There are preferably three winding position groups. This is the minimal equipment, so to speak. The Winding then takes place, for example, in that partial web rolls wound in the winding position groups I and II become. The winding position group III is free and can be used for the preparation of the roll cores become. When the partial web rolls in the winding position II are done, a transition to the roll cores take place in winding position III. The winding position II is then free, so here the corresponding Preparations can be made and the partial lanes then from the winding position group I to the winding position group II be transferred. If then the partial web rolls in the winding position group III finished, they can be placed on the winding position group I will be transferred. In all cases it is possible the individual web rolls in the winding position groups to keep at an axial distance from each other. Yet there is always one winding position group in which the necessary preparations for winding up can hit. An interruption in operation is practical not necessary or at most only very briefly, around the individual partial webs from a winding position group to transfer to another.

Vorzugsweise sind alle Wickelpositionsgruppen zumindest von einer Seite aus zugänglich. Dies erleichtert die Vorbereitung. Von der zugänglichen Seite aus können beispielsweise Rollenkerne eingelegt oder andere Maßnahmen getroffen werden, ohne daß der Bediener von deren Wickelpositionsgruppen behindert wird.All winding position groups are preferably at least accessible from one side. This makes it easier Preparation. Can from the accessible side for example, roll cores inserted or other measures be taken without the operator of their Winding position groups is hindered.

In einer bevorzugten Ausgestaltung wird dies dadurch realisiert, daß die Wickelpositionsgruppen übereinander angeordnet sind. Die Wickelpositionsgruppen sind dann von einer vertikalen Seite aus zugänglich.In a preferred embodiment, this becomes realized that the winding position groups one above the other are arranged. The winding position groups are then accessible from a vertical side.

In einer alternativen Ausgestaltung sind die Wickelpositionsgruppen mit Abstand hintereinander angeordnet, wobei zwischen den Wickelpositionsgruppen Brücken angeordnet sind, unterhalb derer ein Bahnlaufpfad für die Teilbahnen verläuft. Der zuständige Bediener kann dann auf der Brücke stehen, um die Wickelpositionsgruppe vorzubereiten, ohne daß er von der Teilbahn gestört wird.In an alternative embodiment, the winding position groups spaced one behind the other, bridges arranged between the winding position groups are below which a path for the web Partial runs. The responsible operator can then stand on the bridge to the winding position group prepare without being disturbed by the partial web becomes.

Vorzugsweise sind Mittel zum fliegenden Wechsel der Teilbahnen zwischen einzelnen Wickelpositionsgruppen vorgesehen. In diesem Fall ist es nicht einmal erforderlich, den Rollenschneider zum Überleiten der Teilbahnen von einer Wickelpositionsgruppe in die andere anzuhalten. Mittel zum fliegenden Wechsel sind an sich bekannt. Sie bestehen üblicherweise aus einer Trenneinrichtung, die die Teilbahn durchtrennt, und einer Fang- und Leiteinrichtung, die das dann freie Ende der Teilbahn in die neue Wickelpositionsgruppe bringt.Means for flying change are preferred Partial webs between individual winding position groups intended. In this case, it is not even necessary the slitter for transferring the partial webs from one winding position group to the other to stop. Means of flying change are in themselves known. They usually consist of a separation device, which cuts the partial web, and a catch and guide device, which is then the free end of the partial web into the new winding position group.

Vorzugsweise sind die Wickelpositionsgruppen als Stützrollenwickler ausgebildet. Gerade in diesem Fall ist es notwendig, die Stirnseiten frei zugänglich zu halten, weil die Rollenkerne gehalten werden müssen.The winding position groups are preferably in the form of support roller winders educated. In this case it is necessary to keep the end faces freely accessible, because the roll cores have to be held.

Fig. 1a bis 1c zeigen den Wickelabschnitt 1 eines in Fig. 2 in Seitenansicht dargestellten Rollenschneiders 2. Der Rollenschneider 2 weist vor dem Wickelabschnitt eine Schneidstation 3 auf, durch die eine Materialbahn 4 geführt wird, die dann in mehreren Teilbahnen 5 zu Teilbahnrollen 6 aufgewickelt wird. In Fig. 2 ist der Verlauf nur für eine einzige Teilbahn 5 dargestellt. Die Teilbahnrolle 6 ist im Anfangsstadium des Wickelns. 1a to 1c show the winding section 1 of a in Fig. 2 side cutter shown in side view 2. The winder 2 points in front of the winding section a cutting station 3 through which a material web 4 is guided, which then 5 in several partial webs Partial web rolls 6 is wound up. 2 is the Course only shown for a single partial web 5. The partial web roll 6 is in the initial stage of winding.

Die Teilbahnrolle 6 liegt hierbei an einer ersten Stützwalze 7 mit großem Durchmesser und an einer zweiten Stützwalze 8 mit kleinerem Durchmesser an. Der Rollenkern 9 der Teilbahnrolle 6 wird durch seitlich angeordnete Tragarme 10 gehalten, wobei an den Tragarmen 10 ein Antrieb für den Rollenkern 9 vorgesehen sein kann. Der Antrieb kann zusätzlich oder alternativ durch eine der beiden Stützwalzen 7, 8 erfolgen.The partial web roll 6 lies on a first one Back-up roller 7 with a large diameter and on a second Support roller 8 with a smaller diameter. The core of the roll 9 of the partial web roll 6 is arranged laterally Support arms 10 held, on the support arms 10 a drive for the roller core 9 can be provided. The drive can additionally or alternatively by a of the two support rollers 7, 8 take place.

Die Fig. 1a bis 1c zeigen nun schematisch nur den Wikkelabschnitt 1 mit ebenfalls schematisch dargestellten Teilbahnrollen, allerdings ohne die Stützwalzen 7, 8 und die Tragarme 10 und auch ohne den Bahnverlauf.1a to 1c now schematically show only the winding section 1 with also shown schematically Partial web rolls, but without the support rollers 7, 8 and the support arms 10 and also without the course of the path.

Aus der Fig. 1a ist ersichtlich, daß die Teilbahnrollen auf Lücke und versetzt gegeneinander in zwei Wickelpositionsgruppen I und II angeordnet sind. Die Teilbahnrollen werden daher mit 6I und 6II bezeichnet. Jede Teilbahnrolle liegt hierbei in einer Wickelposition. Mehrere Wickelpositionen bilden zusammen eine Wickelpositionsgruppe.From Fig. 1a it can be seen that the partial web rolls are arranged in a gap and offset from one another in two winding position groups I and II. The partial web reels are therefore designated 6 I and 6 II . Each partial web roll is in a winding position. Several winding positions together form a winding position group.

Vorgesehen ist weiterhin eine dritte Wickelpositionsgruppe III, die beim Wickeln der Teilbahnrollen 6I und 6II noch leer ist. Gestrichelt dargestellt sind die Positionen, in denen Teilbahnrollen gewickelt werden können. In diese Positionen wird beispielsweise ein leerer Rollenkern 9 eingelegt oder die Wickelposition auf andere Weise für das Aufwickeln einer Teilbahnrolle vorbereitet. Wenn nun die Teilbahnrollen 6II fertig gewikkelt sind, werden die entsprechenden Teilbahnen, wie dies durch Pfeile 11 angedeutet ist, in die Wickelpositionsgruppe III übergeleitet. Dieser Zustand ist in Fig. 1b dargestellt. In der Wickelpositionsgruppe III werden nun Teilbahnrollen 6III gewickelt. Während dieser Zeit ist die Wickelpositionsgruppe II leer oder frei und kann für das Wickeln neuer Teilbahnrollen vorbereitet werden, wie dies mit gestrichelten Linien dargestellt ist.A third winding position group III is also provided, which is still empty when winding the partial web rolls 6 I and 6 II . The positions in which partial web rolls can be wound are shown in dashed lines. An empty roll core 9 is inserted into these positions, for example, or the winding position is otherwise prepared for winding up a partial web roll. When the partial web rolls 6 II are now finished, the corresponding partial webs, as indicated by arrows 11, are transferred to the winding position group III. This state is shown in Fig. 1b. Partial web rolls 6 III are now wound in the winding position group III. During this time, the winding position group II is empty or free and can be prepared for the winding of new partial web rolls, as shown with broken lines.

Wenn die Teilbahnrollen 6I in der Wickelpositionsgruppe I fertig gewickelt sind, dann können die entsprechenden Teilbahnen in die Wickelpositionsgruppe II übergeleitet werden, wo sich vorbereitete Wickelkerne befinden. Dies ist durch die Pfeile 12 dargestellt. Danach ist die Wickelpositionsgruppe I leer.When the partial web rolls 6 I in the winding position group I have been completely wound, then the corresponding partial webs can be transferred to the winding position group II, where prepared winding cores are located. This is represented by the arrows 12. Then the winding position group I is empty.

In Fig. 1c ist nun dargestellt, daß das Aufwickeln der Teilbahnrollen 6II, 6III in den Wickelpositionsgruppen II und III fortgesetzt wird, und zwar so lange, bis die Teilbahnrollen 6III zu Ende gewickelt sind, also ihren gewünschten Durchmesser erreicht haben. Da die Teilbahnrollen 6II später begonnen worden sind, haben diese ihren Enddurchmesser zu diesem Zeitpunkt noch nicht erreicht. Sie können also weitergewickelt werden, wenn, wie dies durch Pfeile 13 angedeutet ist, die entsprechenden Teilbahnen von der Wickelpositionsgruppe III in die Wickelpositionsgruppe I übergeleitet werden.In Fig. 1c it is now shown that the winding of the partial web rolls 6 II , 6 III in the winding position groups II and III is continued until the partial web rolls 6 III are wound to the end, ie have reached their desired diameter. Since the partial web rolls 6 II were started later, they have not yet reached their final diameter at this time. They can therefore be wound further if, as indicated by arrows 13, the corresponding partial webs are transferred from the winding position group III to the winding position group I.

Man muß zu der Durchführung dieser Vorgehensweise nur dafür sorgen, daß Bahnleitmittel vorhanden sind, die in der Lage sind, die Teilbahnen 5 in jede Wickelpositionsgruppe I, II, III zu führen. Darüber hinaus ist es für das kontinuierliche Wickeln von Vorteil, wenn eine Steuereinrichtung 23 vorgesehen ist, die die einzelnen Wickelpositionsgruppen I-III unabhängig voneinander steuert. Beispielsweise kann eine Wickelpositionsgruppe weiterwickeln, während das Überleiten der Teilbahn 5 von der verbleibenden einen Wickelpositionsgruppe auf die verbleibende andere Wickelpositionsgruppe erfolgt. One only has to carry out this procedure make sure that there are rail guiding means available in are able, the partial webs 5 in each winding position group I, II, III to lead. Beyond that it is advantageous for continuous winding if one Control device 23 is provided, which the individual Winding position groups I-III independently of each other controls. For example, a winding position group continue winding while transferring the partial web 5 from the remaining one winding position group the remaining other winding position group takes place.

Normalerweise benötigt man dann, wenn man mehrere Teilbahnrollen in unterschiedlichen Wickelpositionsgruppen auf Lücke zueinander versetzt aufwickelt, zwei Wickelpositionsgruppen. Mit der erfindungsgemäß Vorgehensweise benötigt man nicht doppelt so viele Wickelpositionsgruppen, um während des Aufwickelns einer Teilbahnrollengruppe das Aufwickeln einer neuen Teilbahnrollengruppe vorzubereiten, sondern lediglich eine Wickelpositionsgruppe mehr. Dies ist gleichzeitig auch eine Wickelpositionsgruppe weniger als das Doppelte der an und für sich benötigten beiden Wickelpositionsgruppen.Usually you need it if you have several partial web rolls in different winding position groups wound in a staggered manner to each other, two winding position groups. With the procedure according to the invention you don't need twice as many winding position groups, around while winding up a partial web roll group winding up a new sub-web reel group prepare, but only a winding position group more. This is also one Winding position group less than double the and two winding position groups required for themselves.

Eine schematische Darstellung einer Realisierungsmöglichkeit zeigen die Fig. 2 und 3.A schematic representation of a possible implementation show FIGS. 2 and 3.

In Fig. 2 ist der Rollenschneider 2 von der Seite zu sehen. Die Wickelpositionsgruppen I-III sind übereinander angeordnet. An der rechten Seite (in der Zeichnung) ist eine Hebebühne 14 vorgesehen, die, wie dies gestrichelt dargestellt ist, unterschiedliche Positionen einnehmen kann, so daß eine Bedienungsperson jede Wickelpositionsgruppe I-III erreichen kann. Mindestens eine Seite dieser Wickelpositionsgruppen ist nämlich frei zugänglich. Hier können dann auch die fertigen Teilbahnrollen entnommen werden.In Fig. 2 the slitter 2 is from the side see. The winding position groups I-III are one above the other arranged. On the right side (in the drawing) a lifting platform 14 is provided which, as shown in dashed lines is shown, take different positions can, so that an operator can each winding position group I-III can achieve. At least one The side of these winding position groups is namely free accessible. The finished partial web rolls can also be used here be removed.

Als Leitmittel 15 dient eine Führungsschiene, auf der auch eine Bahntrenn- und Führungseinrichtung 16 angeordnet ist. Die Bahntrenn- und Führungseinrichtung 16 weist ein Abschlagmesser 17 und ein Führungsband 18 auf, so daß dann, wenn das Abschlagmesser 17 die Teilbahn 5 durchtrennt hat, das Führungsband 18 den neu gebildeten Anfang der Teilbahn 5 ergreifen und einer entsprechenden Wickelposition in einer Wickelpositionsgruppe I-III zuführen kann.A guide rail, on which a web cutting and guiding device 16 is also arranged is. The web cutting and guiding device 16 has a knock-off knife 17 and a guide band 18 on so that when the tee knife 17 the partial web 5 has cut, the guide band 18 the newly formed Take the beginning of sub-web 5 and a corresponding one Winding position in a winding position group I-III can feed.

Das Leitmittel ist unter Steuerung der Steuereinrichtung 23 um einen Schwenkpunkt 19 verschwenkbar, so daß die Teilbahn 5 jede der drei Wickelpositionsgruppen I-III erreichen kann. Dies ist gestrichelt dargestellt.The guidance means is under the control of the control device 23 pivotable about a pivot point 19, so that the partial web 5 each of the three winding position groups I-III can reach. This is shown in dashed lines.

Aus Fig. 3 ist ersichtlich, daß für die vier möglichen Positionen der Teilbahnrollen 6 in der Wickelpositionsgruppe I (nur diese ist von oben zu erkennen) auch vier Leitmittel 15 vorgesehen sind. Die Leitmittel 15 können unabhängig voneinander geschwenkt werden, so daß die Teilbahnen 5 den jeweiligen Wickelpositionsgruppen I-III zugeführt werden können. Beispielsweise kann das erste und dritte Leitmittel 15 von oben die Wickelpositionsgruppe I beschicken, während das zweite und das vierte Leitmittel 15 oben die Wickelpositionsgruppe III beschickt. Das Leitmittel ist aber im Grunde genommen nur zum Beginn des Wickelns erforderlich. Danach kann es gegebenenfalls in eine Ruheposition verschwenkt werden.From Fig. 3 it can be seen that for the four possible Positions of the partial web rolls 6 in the winding position group I (only this can be seen from above) also four Guide means 15 are provided. The guide means 15 can be pivoted independently of one another, so that the Partial webs 5 the respective winding position groups I-III can be supplied. For example, that first and third guide means 15 from above the winding position group I load while the second and that fourth guide means 15 above the winding position group III fed. But the guideline is basically only required at the start of wrapping. After that you can it may be pivoted into a rest position.

Falls eine feinere Auflösung erfolgen soll, kann man das Leitmittel 15 auch noch in mehrere Streifen 20 unterteilen, die ebenfalls unabhängig voneinander verschwenkbar und gegebenenfalls antreibbar sind.If you want a finer resolution, you can divide the guide means 15 into several strips 20, which can also be pivoted independently of one another and can be driven if necessary.

Damit die Teilbahnrollen in den in Fig. 1a und 1c dargestellten Wickelpositionen der Wickelpositionsgruppe I gewickelt werden können, sind die Tragarme 10 in Richtung eines Doppelpfeils 21 verstellbar. Zum Rüsten, d.h. zum Vorbereiten des Wickelns einer neuen Teilbahnrolle, gehört dann auch das axiale Verschieben der Tragarme 10. Dies gilt für alle Wickelpositionsgruppen. So that the partial web rolls in those shown in Fig. 1a and 1c Winding positions of winding position group I can be wound, the support arms 10 are in the direction a double arrow 21 adjustable. For setting up, i.e. to prepare the winding of a new partial web roll, then also includes the axial displacement of the Support arms 10. This applies to all winding position groups.

Die Bahntrenn- und Führungseinrichtung ist nur schematisch dargestellt. Selbstverständlich müssen weitere Teile vorhanden sein, um die Teilbahn 5 um die Stützwalze 7 zu leiten und gegebenenfalls an dem Rollenkern 9 der Teilbahnrolle 6 zu befestigen. Derartige Mittel sind aber an sich bekannt.The web cutting and guiding device is only schematic shown. Of course, others must Parts are present around the sub-web 5 around the backup roller 7 to lead and, if necessary, on the roll core 9 to fix the web roll 6. Such means are known per se.

Fig. 4 zeigt eine Ausgestaltung, bei der die Wickelpositionsgruppen I-III nicht mehr übereinander, sondern hintereinander angeordnet sind. Aus Gründen der Übersicht sind weitere Einzelheiten weggelassen. Zwischen den einzelnen Wickelpositionsgruppen I-III sind Brücken 22 angeordnet, auf denen einen Bedienungsperson gehen kann, um die entsprechenden Wickelpositionsgruppen I-III vorzubereiten. Die Teilbahnen 5 werden unterhalb der Brücken 22 geführt.Fig. 4 shows an embodiment in which the winding position groups I-III no longer one above the other, but are arranged one behind the other. For the sake of clarity further details are omitted. Between The individual winding position groups I-III are bridges 22 arranged on which an operator walk can to the corresponding winding position groups I-III prepare. The partial webs 5 are below the bridges 22 out.

Eine ähnliche Ausgestaltung zeigt Fig. 5. Hier sind die Wickelpositionsgruppen I-III nicht hintereinander, wie in Fig. 4, sondern nebeneinander dargestellt, d.h. die Teilbahnen 5 werden hier von unten zugeführt. Auch hier sind aber Brücken 22 zwischen den einzelnen Wickelpositionsgruppen I-III vorgesehen, um eine Zugänglichkeit zu ermöglichen.A similar configuration is shown in FIG. 5. Here are the Winding position groups I-III not in a row, like in Fig. 4, but shown side by side, i.e. the Partial webs 5 are fed from below. Here too but there are bridges 22 between the individual winding position groups I-III provided for accessibility to enable.
