Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung eines ersten und eines zweiten Strangs der Tabak verarbeitenden Industrie, wobei die Stränge jeweils wenigstens zwei Lagen eines gewickelten flächigen Materials aufweisen. Die Erfindung betrifft ferner die Verwendung einer derartigen Vorrichtung.The invention relates to a device for producing a first and a second strand for the tobacco processing industry, the strands each having at least two layers of a wound flat material. The invention also relates to the use of such a device.

Im Stand der Technik existieren Vorrichtungen zur Herstellung von zwei Strängen der Tabak verarbeitenden Industrie, bei denen die Stränge ein doppellagiges Umhüllungsmaterial aufweisen oder aber Hohlstränge aus doppellagigem Material hergestellt werden. Hierbei ist der Materialstreifen und das relative Positionieren zueinander und zu einer Formatvorrichtung, in der der Strang gebildet wird bzw. geformt wird, wichtig.In the prior art, there are devices for producing two strands in the tobacco processing industry, in which the strands have a double-layered covering material or hollow strands are produced from a double-layered material. Here, the strip of material and the relative positioning to one another and to a format device in which the strand is formed or is formed is important.

So ist beispielsweise aus der EP 2 574 244 B1 eine Vorrichtung bekannt, bei der band- oder streifenförmiges Material, hier Papier, von einer Bobine abgewickelt wird. In einer Herstellmaschine wird das Papier um einen Tabak- oder Filterstrang herumgeschlagen und verklebt. In diesem Dokument ist eine Vorrichtung gezeigt, in der das Papier in zwei Papierstreifen doppelter Breite zugeführt wird, in zwei parallele Stränge geschnitten, übereinandergelegt und anschließend übereinanderliegend einer nachfolgenden Herstellmaschine zugeführt wird. Hierbei läuft das Umhüllungsmaterial in verschiedenen Materialläufen.For example, from the EP 2 574 244 B1 a device is known in which the band or strip-like material, here paper, is unwound from a bobbin. In a manufacturing machine, the paper is wrapped around a tobacco or filter rod and glued. In this Document shows a device in which the paper is fed in two strips of paper of twice the width, cut into two parallel strands, placed one on top of the other and then fed one on top of the other to a downstream manufacturing machine. The wrapping material runs in different material runs.

Bisher sind entsprechende Vorrichtungen darauf angelegt, eine bestimmte Sorte eines Strangs herzustellen, d.h. dass das Umhüllungsmaterial gleich ist. Insbesondere bei der Herstellung von Hohlsträngen aus doppellagigem Material sind bekannte Vorrichtungen relativ unflexibel bei der Veränderung der Materiallagen, insbesondere dann, wenn die Lagen der Umhüllungsmaterialstreifen oder der Hohlstränge variiert werden sollen.So far, corresponding devices have been designed to produce a specific type of strand, i.e. the sheathing material is the same. Especially when producing hollow strands from double-layered material, known devices are relatively inflexible when changing the layers of material, especially when the layers of the strips of wrapping material or of the hollow strands are to be varied.

Es ist Aufgabe der vorliegenden Erfindung, eine variable Vorrichtung zur Herstellung eines ersten und eines zweiten Strangs der Tabak verarbeitenden Industrie anzugeben, wobei mit nur sehr wenigen Umbaumaßnahmen verschiedene Stränge herstellbar sind.It is the object of the present invention to specify a variable device for producing a first and a second strand in the tobacco processing industry, with different strands being able to be produced with only very few conversion measures.

Gelöst wird diese Aufgabe durch eine Vorrichtung gemäß Anspruch 1 zur Herstellung eines ersten und eines zweiten Strangs der Tabak verarbeitenden Industrie, wobei die Stränge jeweils wenigstens zwei Lagen eines gewickelten flächigen Materials, d.h. eines von wenigstens einer Bobinenvorrichtung abgezogenen Materials, aufweisen, wobei in einer ersten Betriebsart der Vorrichtung das flächige Material für den ersten Strang aus einer ersten Bobinenvorrichtung abziehbar ist und über einen ersten Materiallauf zu einer ersten Strangformungsvorrichtung förderbar ist und das flächige Material für den zweiten Strang aus einer zweiten Bobinenvorrichtung abziehbar ist und über einen zweiten Materiallauf zu einer zweiten Strangformungsvorrichtung förderbar ist, wobei in einer zweiten Betriebsart der Vorrichtung das flächige Material für den ersten Strang aus der ersten und der zweiten Bobinenvorrichtung abziehbar ist und über einen dritten Materiallauf zu der ersten Strangformungsvorrichtung förderbar ist und das flächige Material für den zweiten Strang aus der ersten und der zweiten Bobinenvorrichtung abziehbar ist und über einen vierten Materiallauf zu der zweiten Strangformungsvorrichtung förderbar ist.This object is achieved by a device according to claim 1 for the production of a first and a second strand of the tobacco processing industry, wherein the strands each have at least two layers of a wound flat material, ie a material drawn from at least one bobbin device, wherein in a first Operating mode of the device the flat material for the first strand can be drawn off from a first bobbin device and can be conveyed via a first material run to a first strand-shaping device and the sheet-like material for the second strand can be drawn off from a second bobbin device and via a second material run to a second strand-shaping device can be conveyed, wherein in a second operating mode of the device the flat material for the first strand can be drawn off from the first and the second bobbin device and can be conveyed via a third material run to the first strand-forming device and the flat material for the second strand can be drawn off from the first and the second bobbin device and can be conveyed to the second strand-forming device via a fourth material run.

Die Aufgabe wird weiterhin durch die im Anspruch 15 beschriebene Verwendung der Vorrichtung gelöst.The object is further achieved by the use of the device described in claim 15 .

Durch Vorsehen von verschiedenen Materialläufen in den beiden Betriebsarten ist eine sehr effiziente Änderung der Lagen in den hergestellten Strängen mit wenig Umbauzeit möglich.By providing different material flows in the two operating modes, the layers in the strands produced can be changed very efficiently with little changeover time.

Wenn vorzugsweise in der zweiten Betriebsart sich der dritte und vierte Materiallauf im Betrieb der Vorrichtung wenigstens teilweise kreuzen, können mit wenigen konstruktiven Teilen verschiedene Betriebsarten realisiert werden. Insbesondere kreuzen sich der erste und zweite Materiallauf in der ersten Betriebsart vorzugsweise nicht. Insbesondere ist unter einem Kreuzen des dritten und vierten Materiallaufs zu verstehen, dass sich das in dem Materiallauf befindliche flächige Material oder ein Teil hiervon, insbesondere mit einem Abstand voneinander, kreuzt.If, preferably in the second mode of operation, the third and fourth material flow at least partially intersect during operation of the device, different modes of operation can be implemented with few structural parts. In particular, the first and second material run preferably do not cross in the first mode of operation. In particular, a crossing of the third and fourth material run is to be understood as meaning that the flat material located in the material run or a part thereof crosses, in particular at a distance from one another.

Wenn vorzugsweise der ersten Strangformungsvorrichtung eine erste schwenkbare Führungsvorrichtung zugeordnet ist, die das flächige Material in der ersten Betriebsart in dem ersten Materiallauf führt und in der zweiten Betriebsart in dem dritten Materiallauf führt, wobei eine Änderung eines Schwenkwinkels der Führungsvorrichtung eine Drehung des mittels der ersten Strangformungsvorrichtung gebildeten Strangs um dessen Längsachse hervorruft, ist eine sehr effiziente Führung des flächigen Materials in dem ersten Materiallauf sowie dem dritten Materiallauf möglich. Zudem kann die gleiche Führungsvorrichtung für beide Betriebsarten verwendet werden, so dass der apparative Aufwand minimiert ist.If preferably the first strand-shaping device is assigned a first pivotable guide device, which guides the flat material in the first mode of operation in the first material run and in the second mode of operation in the third material run, with a change in a pivoting angle of the guide device causing a rotation of the means of the first strand-shaping device formed strand causes about its longitudinal axis, a very efficient guidance of the sheet material in the first run of material and the third run of material is possible. In addition, the same guiding device can be used for both operating modes, so that the outlay on equipment is minimized.

Die schwenkbare Führungsvorrichtung, die vorzugsweise eine auf einer Schwenkplatte angeordnete Führungsvorrichtung ist, ist beispielsweise in der EP 3 056 097 A1 der Anmelderin offenbart. Diese dient insbesondere dazu, die Lage der geführten Materialbahn genau einzustellen. Entsprechende Sensoren, die die Lage der Kanten der Materialbahn sensieren, sind hierzu vorzugsweise vorgesehen.The pivotable guide device, which is preferably a guide device arranged on a pivot plate, is disclosed, for example, in US Pat EP 3 056 097 A1 disclosed to the applicant. This serves in particular to adjust the position of the guided web of material precisely. Corresponding sensors, which sense the position of the edges of the material web, are preferably provided for this purpose.

Vorzugsweise ist der zweiten Strangformungsvorrichtung eine zweite schwenkbare Führungsvorrichtung zugeordnet, die das flächige Material in der ersten Betriebsart in dem zweiten Materiallauf führt und in der zweiten Betriebsart in dem vierten Materiallauf führt, wobei eine Änderung eines Schwenkwinkels der Führungsvorrichtung eine Drehung des mittels der zweiten Strangformungsvorrichtung gebildeten Strangs um dessen Längsachse hervorruft. Die zweite schwenkbare Führungsvorrichtung kann somit auch in beiden Betriebsarten verwendet werden, was den apparativen Aufwand der erfindungsgemäßen Vorrichtung minimiert. Auch die zweite schwenkbare Führungsvorrichtung ist vorzugsweise eine Führungsvorrichtung, die auf einer zweiten Schwenkplatte angeordnet ist und einer in EP 3 056 097 A1 beschriebenen Führungsvorrichtung entspricht.A second pivotable guide device is preferably assigned to the second strand-forming device, which guides the flat material in the second material run in the first operating mode and in the fourth material run in the second operating mode, with a change in a pivoting angle of the guide device causing a rotation of the material formed by the second strand-forming device Strand causes around its longitudinal axis. The second pivotable guide device can thus also be used in both operating modes, which minimizes the expenditure on equipment of the device according to the invention. The second pivotable guide device is also preferably a guide device which is arranged on a second pivot plate and has an in EP 3 056 097 A1 described guide device corresponds.

Vorzugsweise ist die erste Führungsvorrichtung horizontal von der zweiten Führungsvorrichtung versetzt angeordnet, wobei insbesondere die erste Führungsvorrichtung vertikal von der zweiten Führungsvorrichtung versetzt angeordnet ist. Hierdurch wird erreicht, dass sowohl für einen ersten Strang als auch für einen zweiten Strang eine entsprechende effiziente Lageregelung der Materialstreifen ermöglicht ist. Vorzugsweise sind hierbei die erste Führungsvorrichtung und die zweite Führungsvorrichtung unabhängig voneinander verschwenkbar, so dass für jeden hergestellten Strang eine unabhängige Steuerbarkeit oder Regelbarkeit der Lage der Materialbahnen möglich ist.Preferably, the first guiding device is arranged offset horizontally from the second guiding device, wherein in particular the first guiding device is arranged offset vertically from the second guiding device. The result of this is that a correspondingly efficient position control of the material strips is made possible both for a first strand and for a second strand. Preferably, the first guide device and the second guide device can be pivoted independently of one another, so that the position of the material webs can be independently controlled or regulated for each strand produced.

Wenn vorzugsweise stromabwärts der ersten Bobinenvorrichtung eine erste Materialzugschneidvorrichtung und stromabwärts der zweiten Bobinenvorrichtung eine zweite Materialzugschneidvorrichtung vorgesehen sind, wobei die Materialzugschneidvorrichtungen ausgebildet sind, das flächige Material aus den jeweiligen Bobinenvorrichtungen abzuziehen und das flächige Material längsaxial in jeweils zwei Bahnen zu schneiden, können mit zwei Bobinenvorrichtungen, die jeweils eine Bobine aufweisen, sehr effizient zwei doppellagige Stränge hergestellt werden. Eine Materialzugschneidvorrichtung hat die Funktion, ein Material, beispielsweise ein Umhüllungsmaterial oder eine Papierbahn, aus einer Bobinenvorrichtung abzuziehen und dieses Material mittig oder im Wesentlichen in der Mitte in längsaxialer Richtung zu schneiden, um zwei Materialbahnen zu erzeugen, die dann dazu dienen, einen Strang der Tabak verarbeitenden Industrie zu umhüllen oder alternativ zu einem Hohlstrang ausgebildet zu werden. Sollte eine Bobinenvorrichtung beispielsweise zwei Bobinen aufweisen, die schon eine entsprechende Breite des Materials aufweisen, das für die Weiterverarbeitung benötigt wird, kann die Materialzugschneidvorrichtung auch als eine Materialzugvorrichtung ausgebildet sein. In diesem Fall kann also die Schneidfunktion wegfallen. Im Rahmen der Erfindung beinhaltet der Begriff "Materialzugschneidvorrichtung" also auch eine Materialzugvorrichtung. Ferner kann im Rahmen der Erfindung eine Bobinenvorrichtung sowohl eine als auch zwei Bobinen aufnehmen, von der dann Material abgezogen wird bzw. werden.If a first material-pulling cutting device is preferably provided downstream of the first bobbin device and a second material-drawing cutting device downstream of the second bobbin device, with the material-pulling cutting devices being designed to pull the flat material out of the respective bobbin devices and to cut the flat material longitudinally and axially into two webs each, two bobbin devices can be used , each having a bobbin, two double-layer strands can be produced very efficiently. One Material pull cutting device has the function of pulling a material, for example a wrapping material or a paper web, from a bobbin device and cutting this material in the middle or substantially in the middle in the longitudinal axial direction in order to produce two material webs, which then serve to form a rod of tobacco processing industry or alternatively to be formed into a hollow strand. If a bobbin device has, for example, two bobbins that already have a corresponding width for the material that is required for further processing, the material pulling cutting device can also be designed as a material pulling device. In this case, the cutting function can be omitted. Within the scope of the invention, the term “material pulling cutting device” also includes a material pulling device. Furthermore, within the scope of the invention, a bobbin device can accommodate both one and two bobbins, from which material is or are then withdrawn.

Beim Schneiden des Materials, das von der Bobine abzogen wurde, kann ein mittiger Schnitt ausgeführt werden, beispielsweise dann, wenn die geschnittenen Materialbahnen die gleiche Lage in den gebildeten Strängen ausbilden sollen, beispielsweise die äußere Lage oder die innere Lage. Sofern aus einer Materialbahn, die von einer Bobine abgezogen wird, das Material nur eines Strangs geschnitten wird, ist es sinnvoll, den Schnitt nicht ganz mittig zu setzen, sondern so, dass die äußere Bahn bzw. die Bahn, aus der die äußere Lage des Stangs gebildet wird, eine etwas größere Breite aufweist als die innere Bahn des Strangs bzw. die Bahn, aus der die innere Lage des Strangs gebildet wird.When cutting the material that has been drawn off the bobbin, a center cut can be made, for example when the cut webs of material are to form the same layer in the strands being formed, for example the outer layer or the inner layer. If the material of only one strand is cut from a material web that is pulled off a bobbin, it makes sense not to make the cut in the middle, but in such a way that the outer web or the web from which the outer layer of the shank is formed has a slightly greater width than the inner web of the shank or the sheet from which the inner layer of the skein is formed.

Wenn vorzugsweise in der ersten Betriebsart die erste Materialzugschneidvorrichtung im ersten Materiallauf vorgesehen ist, wobei die Vorrichtung dazu ausgebildet ist, aus dem von der ersten Materialzugschneidvorrichtung in zwei Bahnen geschnittene flächige Material eine äußere und eine innere Lage für den ersten Strang zu bilden, wobei insbesondere eine Steuervorrichtung vorgesehen ist, mittels der eine Zugspannung der zwei Bahnen zwischen der ersten Materialzugschneidvorrichtung und der ersten Strangformungsvorrichtung gemeinsam, insbesondere auf einen gleichen Wert, gesteuert wird, ist ein besonders effizienter Betrieb der Vorrichtung möglich. Die Steuervorrichtung kann hierbei beispielsweise einen sogenannten Tänzer aufweisen, um den das geschnittene flächige Material umgelenkt wird oder um den dieses Material läuft, wobei durch den Tänzer bzw. die Steuervorrichtung eine entsprechende Spannung der Materialbahnen zwischen der ersten Materialzugschneidvorrichtung und der ersten Strangformungsvorrichtung eingestellt werden kann.If, preferably in the first operating mode, the first material cutting device is provided in the first material run, the device being designed to form an outer and an inner layer for the first strand from the flat material cut into two webs by the first material cutting device, with in particular one Control device is provided by means of a tensile stress of the two webs between the first material cutting device and the first strand-forming device is controlled jointly, in particular to the same value, particularly efficient operation of the device is possible. The control device can have a so-called dancer, for example, around which the cut flat material is deflected or around which this material runs, with the dancer or the control device being able to set a corresponding tension of the material webs between the first material cutting device and the first strand-forming device.

Ein weiterer besonders effizienter Betrieb ist dann gegeben, wenn in der ersten Betriebsart die zweite Materialzugschneidvorrichtung im zweiten Materiallauf vorgesehen ist, wobei die Vorrichtung ausgebildet ist, aus dem von der zweiten Materialzugschneidvorrichtung in zwei Bahnen geschnittene flächige Material eine äußere und eine innere Lage für den zweiten Strang zu bilden, wobei insbesondere eine Steuervorrichtung vorgesehen ist, mittels der eine Zugspannung der zwei Bahnen zwischen der zweiten Materialzugschneidvorrichtung und der zweiten Strangformungsvorrichtung gemeinsam, insbesondere auf einen gleichen Wert, gesteuert wird.Another particularly efficient operation is given when, in the first operating mode, the second material cutting device is provided in the second material run, the device being designed to form an outer and an inner layer for the second To form strand, in particular a control device is provided, by means of which a tension of the two webs between the second material cutting device and the second strand-forming device is controlled together, in particular to an equal value.

Auch hier umfasst die Steuervorrichtung vorzugsweise einen sogenannten Tänzer, um den die Bahnen gelenkt sind und der dazu dient, eine Zugspannung der zwei Bahnen zwischen der zweiten Materialzugschneidvorrichtung und der zweiten Strangformungsvorrichtung zu steuern bzw. einzustellen.Here, too, the control device preferably comprises a so-called dancer, around which the webs are guided and which serves to control or adjust a tension of the two webs between the second material-drawing device and the second strand-forming device.

Vorzugsweise ist vorgesehen, dass in der zweiten Betriebsart die Bahnen, die von der ersten Materialzugschneidvorrichtung aus flächigem Material geschnitten sind, so in dem dritten und vierten Materiallauf förderbar sind, dass diese als äußere Lagen des ersten und des zweiten Strangs dienen, wobei insbesondere in der ersten schwenkbaren Führungsvorrichtung die eine Bahn und in der zweiten schwenkbaren Führungsvorrichtung die andere Bahn umlenkbar sind.It is preferably provided that in the second mode of operation the webs, which are cut from flat material by the first material pull-cutting device, can be conveyed in the third and fourth material run in such a way that they serve as outer layers of the first and second strand, with particularly in the first pivoting guide device one path and the other path can be deflected in the second pivotable guide device.

Wenn vorzugsweise eine Steuervorrichtung vorgesehen ist, die die Zugspannung der zwei Bahnen, die in dem dritten und vierten Materiallauf förderbar sind und insbesondere als äußere Lagen des ersten und des zweiten Strangs dienen, getrennt voneinander, insbesondere zeitweise mit unterschiedlichen Werten, steuert, kann sehr effizient in der zweiten Betriebsart die Vorrichtung betrieben werden. Insbesondere kommen die äußeren Lagen des ersten und des zweiten Strangs in Kontakt mit jeweils einem Formatband der ersten und der zweiten Strangformungsvorrichtung, so dass über die Steuerung der Zugspannung der beiden Bahnen, die im Strang die äußeren Lagen bilden, auch sehr gezielt die Strangfördergeschwindigkeit der Strangformungsvorrichtung eingestellt werden kann.If a control device is preferably provided, which controls the tension of the two webs, which can be conveyed in the third and fourth material run and in particular serve as outer layers of the first and second strand, separately from one another, in particular with different values at times, can be very efficient in the second operating mode the device can be operated. In particular, the outer layers of the first and second strand come into contact with a format belt of the first and second strand-shaping device, so that by controlling the tension of the two webs that form the outer layers in the strand, the strand conveying speed of the strand-shaping device can also be controlled in a very targeted manner can be adjusted.

Vorzugsweise sind die Bahnen, die in der zweiten Betriebsart von der zweiten Materialzugschneidvorrichtung aus flächigem Material geschnitten sind, so in dem dritten und vierten Materiallauf förderbar, dass diese direkt auf den Formatbändern der ersten Strangformungsvorrichtung und der zweiten Strangformungsvorrichtung aufliegen, wobei insbesondere in der ersten schwenkbaren Führungsvorrichtung die eine Bahn und in der zweiten schwenkbaren Führungsvorrichtung die andere Bahn umlenkbar sind.Preferably, the webs that are cut from flat material by the second material pull-cutting device in the second operating mode can be conveyed in the third and fourth material run in such a way that they lie directly on the format belts of the first strand-forming device and the second strand-forming device, with pivoting in the first in particular Guide device which can be deflected in one track and in the second pivotable guide device the other track.

Wenn vorzugsweise eine Steuervorrichtung vorgesehen ist, mittels der die Zugspannung der zwei Bahnen, die als innere Lagen des ersten und den zweiten Strangs dienen, zwischen der zweiten Materialzugschneidvorrichtung und der ersten und der zweiten Strangformungsvorrichtung gemeinsam, insbesondere auf einen gleichen Wert, gesteuert werden, kann die Vorrichtung auch sehr effizient und mit wenigen maschinellen Komponenten betrieben werden.If a control device is preferably provided, by means of which the tension of the two webs, which serve as inner layers of the first and the second strand, can be controlled jointly, in particular to an equal value, between the second material tension cutting device and the first and the second strand forming device the device can also be operated very efficiently and with few mechanical components.

Vorzugsweise sind stromaufwärts der ersten Strangformungsvorrichtung und der zweiten Strangformungsvorrichtung jeweils nur eine Spreizvorrichtung vorgesehen, mittels der in jedem Materiallauf eine Bahn des geschnittenen flächigen Materials in einer Ebene der jeweiligen Bahn quer zur Förderrichtung der Bahn verschiebbar ist, so dass eine überlappende Verbindung jeweils einer äußeren Bahn mit einer inneren Bahn ermöglicht ist. Unter der überlappenden Verbindung der Bahnen ist im Rahmen der Erfindung insbesondere zu verstehen, dass die Bahnen so überlappen, dass diese im Strang als äußere Lage um eine innere Lage wickelbar sind, wobei die äußere Lage und die innere Lage durch vorherige Überlappung der diese Lage bildenden Bahnen miteinander verklebbar sind. Hierdurch kann mit sehr wenig Komponenten der Vorrichtung eine effiziente Überlappung der jeweiligen Bahnen miteinander und ein entsprechendes effizientes Verkleben der Bahnen zu Doppelbahnen bzw. zu Doppellagen vorgesehen sein.Preferably upstream of the first strand forming device and the second rope-forming device, only one spreading device is provided in each case, by means of which a web of the cut flat material in each material run can be displaced in a plane of the respective web transversely to the conveying direction of the web, so that an overlapping connection of an outer web with an inner web is made possible . In the context of the invention, the overlapping connection of the webs is to be understood in particular as meaning that the webs overlap in such a way that they can be wound around an inner layer in the strand as an outer layer, the outer layer and the inner layer forming this layer by previously overlapping them Webs are glued together. As a result, an efficient overlapping of the respective webs with one another and a correspondingly efficient gluing of the webs to form double webs or double layers can be provided with very few components of the device.

Die Aufgabe wird ferner gelöst durch die Verwendung einer erfindungsgemäßen oder bevorzugt ausgestalteten Vorrichtung zum Herstellen von doppellagigen Hohlsträngen, insbesondere von Papierhohlröhrchen, der Tabak verarbeitenden Industrie.The object is also achieved through the use of a device according to the invention or a preferred embodiment for producing double-layer hollow strands, in particular hollow paper tubes, in the tobacco processing industry.

Vorzugsweise sind die beiden Lagen der Hohlstränge aus dem gleichen Material.The two layers of the hollow strands are preferably made of the same material.

Ferner vorzugsweise sind die beiden Lagen der Hohlstränge aus unterschiedlichem Material, wobei insbesondere die äußeren Lagen der beiden Hohlstränge aus dem gleichen Material sind. Hierbei können dann die inneren Lagen der beiden Hohlstränge aus einem anderen, allerdings auch gleichen, Material im Vergleich zu den äußeren Lagen sein.Furthermore, the two layers of the hollow strands are preferably made of different materials, with the outer layers of the two hollow strands in particular being made of the same material. In this case, the inner layers of the two hollow strands can then be made of a different material than the outer layers, although they can also be the same.

In den Zeichnungen sind jeweils gleiche oder gleichartige Elemente und/oder Teile mit denselben Bezugsziffern versehen, so dass von einer erneuten Vorstellung jeweils abgesehen wird.In the drawings, elements and/or parts that are the same or of the same type are provided with the same reference numbers, so that they are not presented again in each case.

Fig. 1 zeigt eine schematische Darstellung einer erfindungsgemäßen Vorrichtung in einer ersten Betriebsart. Hierbei sind ein erster Materiallauf und ein zweiter Materiallauf gezeigt. Der erste Materiallauf beinhaltet das Material, beispielsweise eine Papierbahn, das von einer Bobine 1, die auf einer ersten Bobinenvorrichtung angeordnet ist, zu einer vorderen Strangformungsvorrichtung 14 geführt wird. Die Begrifflichkeit "vorderer oder hinterer" ist in Bezug auf die Fig. 1 in Bezug zur Zeichenebene gemeint. 1 shows a schematic representation of a device according to the invention in a first operating mode. Here, a first run of material and a second run of material are shown. The first material run includes the material, for example a paper web, which is guided to a front strand forming device 14 from a bobbin 1 which is arranged on a first bobbin device. The terminology "front or rear" is in relation to the 1 in relation to the plane of the drawing.

Hierbei soll die erste Bobine 1 näher zum Betrachter der Fig. 1 angeordnet sein als die zweite Bobine 8. Dies ist in Fig. 2 noch einmal schematisch gezeigt. Die erste Bobine 1 liegt in der Betrachtungsrichtung vor der zweiten Bobine 8. Entsprechend ist die erste Strangformungsvorrichtung 14, umfassend das vordere Formatband 14a, vor der zweiten Strangformungsvorrichtung 7, umfassend das hintere Formatband 7a, angeordnet. Dies soll schematisch durch die dreidimensionalen Darstellungen der Fig. 2 und 3 erläutert werden.Here, the first bobbin 1 is closer to the viewer 1 be arranged as the second bobbin 8. This is in 2 shown again schematically. The first bobbin 1 is in front of the second bobbin 8 in the viewing direction. Accordingly, the first strand-forming device 14, comprising the front format belt 14a, is arranged in front of the second strand-forming device 7, comprising the rear format belt 7a. This should be done schematically by the three-dimensional representations of the Figures 2 and 3 be explained.

Der erste Materiallauf ist somit in Betrachtungsrichtung vor dem zweiten Materiallauf in Fig. 1 angeordnet. Entsprechend ist auch die dort dargestellte erst Schwenkplatte 6 in Betrachtungsrichtung vor der zweiten Schwenkplatte 13 angeordnet, d.h. horizontal voneinander beabstandet. Damit ist eine Zuführung der Materialbahnen zu der ersten Strangformungsvorrichtung und der zweiten Strangformungsvorrichtung deutlich effizienter und einfacher möglich.The first run of material is thus in front of the second run of material in the viewing direction 1 arranged. Correspondingly, the first pivoting plate 6 shown there is also arranged in front of the second pivoting plate 13 in the viewing direction, ie horizontally spaced from one another. This makes it possible to feed the material webs to the first strand-shaping device and the second strand-shaping device much more efficiently and easily.

In dem ersten Materiallauf wird von einer Bobinenvorrichtung bzw. ersten Bobine 1 eine Papierbahn im Wesentlichen doppelter Gebrauchsbreite von einer Materialzugschneidvorrichtung 3 abgezogen, und zwar über eine ohne Bezugszeichen dargestellte Rolle. Die Materialzugschneidvorrichtung 3 zieht das Material von der Bobine 1 ab und schneidet die abgezogene Materialbahn in zwei Bahnen 1a, 1b, wie schematisch in Fig. 2 dargestellt ist. Diese beiden Bahnen 1a, 1b werden gemeinsam um einen Tänzer 2 geführt und über weitere Rollen getrennt auf deren Förderweg weitergefördert. Dies geschieht in dem Ausführungsbeispiel der Fig. 2 nach zwei Rollen in Förderrichtung hinter dem Tänzer 2. Der Tänzer 2 ist Teil einer Steuervorrichtung, die dafür sorgt, dass die Zugspannung der Papierbahnen 1a, 1b auf einen vorgegebenen oder einen vorgebbaren Wert eingestellt oder gesteuert werden kann.In the first run of material, a paper web of essentially twice the useful width is pulled off a material pull cutting device 3 from a bobbin device or first bobbin 1, specifically via a roller shown without a reference number. The material pull-cutting device 3 pulls the material from the bobbin 1 and cuts the pulled-off material web into two webs 1a, 1b, as shown schematically in FIG 2 is shown. These two webs 1a, 1b are guided together around a dancer 2 and further conveyed separately on their conveying path via further rollers. This is done in the embodiment of FIG 2 after two rollers in the conveying direction behind the dancer 2. The dancer 2 is part of a control device which ensures that the tension of the paper webs 1a, 1b can be set or controlled to a predetermined or a predetermined value.

Die Papierbahn 1a, die in dem gebildeten Strang die äußere Bahn darstellt, gelangt dann zu einer ersten Schwenkplatte 6. Auf dieser Schwenkplatte 6 wird mittels einer Leimauftragsvorrichtung 5 Leim aufgetragen.The paper web 1a, which represents the outer web in the strand formed, then reaches a first pivoting plate 6. Glue is applied to this pivoting plate 6 by means of a glue application device 5.

Die Papierbahn 1b gelangt zu einer Spreizvorrichtung 4, die ausgebildet ist, die Lage der Papierbahn 1b in Betrachtungsrichtung der Fig. 1 der Lage der Papierbahn 1a anzupassen, so dass diese fast vollständig überlappen. Anschließend gelangt die Papierbahn 1b über weitere Rollen auch zu der ersten Schwenkplatte 6 und von dort gelangen beide Papierbahnen 1a, 1b über jeweils eine Rolle in die Strangformungsvorrichtung 14, die eine übliche Formatvorrichtung sein kann und beispielsweise ein Formatband 14a aufweist. In der Formatvorrichtung werden die beiden Papierbahnen 1a, 1b zu einem Hohlstrang ausgebildet. Dieser kann dann anschließend in Hohlröhrchen abgelängt werden.The paper web 1b arrives at a spreading device 4, which is designed to position the paper web 1b in the viewing direction 1 adapt to the position of the paper web 1a so that they overlap almost completely. Then the paper web 1b also reaches the first swivel plate 6 via further rollers and from there both paper webs 1a, 1b reach the strand forming device 14 via one roller each, which can be a conventional format device and has, for example, a format belt 14a. In the format device, the two paper webs 1a, 1b are formed into a hollow strand. This can then be cut to length in hollow tubes.

Der zweite Materiallauf ist in diesem Fall der untere. Dieser ist an sich symmetrisch zu dem ersten Materiallauf angeordnet. Es wird mittels einer Materialzugschneidvorrichtung 9 ein flächiges Material abgezogen, und zwar über eine Rolle gelenkt abgezogen, um dieses flächige Material in zwei Papierbahnen 8a, 8b zu schneiden. Die Papierbahn 8a dient dazu, in der zweiten Strangformungsvorrichtung die äußere Papierbahn bzw. Papierlage zu bilden, und die Papierbahn 8b dazu, in der zweiten Strangformungsvorrichtung 7 die innere Papierbahn bzw. Papierlage zu bilden.The second run of material in this case is the bottom one. This is arranged symmetrically to the first material flow. A flat material is pulled off by means of a material pull cutting device 9, specifically drawn off in a guided manner via a roller, in order to cut this flat material into two paper webs 8a, 8b. The paper web 8a is used to form the outer paper web or paper layer in the second rope-forming device, and the paper web 8b is used to form the inner paper web or paper layer in the second rope-forming device 7 .

Die zwei Papierbahnen 8a, 8b werden gemeinsam um einen Tänzer 10 geführt.The two paper webs 8a, 8b are guided together around a dancer 10.

Die innere Papierbahn 8b gelangt anschließend geführt über einige Rollen zu der zweiten Schwenkplatte 13 und von da über eine entsprechende Rolle zu der zweiten Strangformungsvorrichtung 7.The inner paper web 8b is then guided over a few rollers to the second pivoting plate 13 and from there over a corresponding roller to the second rope-forming device 7.

Die äußere Papierbahn 8a gelangt über einige Rollen zu einer Spreizvorrichtung 11, die wie die Spreizvorrichtung 4 wirkt, und von dort über Rollen zur zweiten Schwenkvorrichtung 13, auf der ein Leim durch eine Leimauftragsvorrichtung 12 aufgetragen wird, damit die Papierbahnen 8a, 8b miteinander verklebt werden können.The outer paper web 8a passes over some rollers to a spreader 11, which acts like the spreader 4, and from there over rollers to the second pivoting device 13, on which a glue is applied by a glue applicator 12 so that the paper webs 8a, 8b are glued together can.

Es bilden sich zwei Stränge 20, 21 aus, die eine äußere und eine innere Lage haben, die aus dem gleichen Material besteht. Das Material der jeweiligen Bobinen kann hier unterschiedlich sein aber auch gleich sein. Es können somit zwei gleiche Stränge gebildet werden oder zwei Stränge aus zwei unterschiedlichen Materialien. Mit dem Verschwenken der Schwenkplatten 6, 13 können die Nähte der gebildeten Stränge in Rotationsrichtung der Stränge verändert werden.Two strands 20, 21 form, one outer and one inner have a layer made of the same material. The material of the respective bobbins can be different but also be the same. It is thus possible to form two identical strands or two strands made from two different materials. By pivoting the pivot plates 6, 13, the seams of the strands formed can be changed in the direction of rotation of the strands.

Die zweite Betriebsart der erfindungsgemäßen Vorrichtung ist in den Fig. 4 bis 6 schematisch dargestellt. Im Unterschied zur ersten Betriebsart wird in der zweiten Betriebsart das Material bzw. die Papierbahnen 1a, 1b, die von der ersten Bobinenvorrichtung 1 abgezogen werden, durch die erste Materialzugschneidvorrichtung 3 entsprechend abgezogen und in die Papierbahnen 1a, 1b geschnitten und dann als äußere Papierbahnen zur Bildung des vorderen und des hinteren Strangs in der ersten und der zweiten Strangformungsvorrichtung in dem dritten Materiallauf und dem vierten Materiallauf gefördert.The second mode of operation of the device according to the invention is in the Figures 4 to 6 shown schematically. In contrast to the first operating mode, in the second operating mode the material or the paper webs 1a, 1b, which are drawn off from the first bobbin device 1, are drawn off accordingly by the first material pull cutting device 3 and cut into the paper webs 1a, 1b and then as outer paper webs to the Formation of the leading and trailing strands in the first and second strand forming devices in the third material run and the fourth material run is promoted.

Hierbei gelangt die Papierbahn 1a über die erste Schwenkplatte 6 und die Beleimvorrichtung 5 zu der ersten Strangformungsvorrichtung 14 und die zweite Papierbahn 1b über die Spreizvorrichtung 4 und die zweite Schwenkplatte 13 zu der zweiten Strangformungsvorrichtung 7. Die inneren Papierbahnen werden durch das von der zweiten Bobine 8 abgezogene flächige Material, das durch die zweite Materialzugschneidvorrichtung abgezogen wird und entsprechend in die Papierbahnen 8a, 8b geschnitten wird, auch über den dritten und vierten Materiallauf zu den beiden Strangformungsvorrichtungen 14, 7 gefördert. Die Papierbahn 8a gelangt über die Spreizvorrichtung 11 zu der ersten Schwenkplatte 6 und von dort in die erste Strangformungsvorrichtung 14. Die zweite Papierbahn 8b gelangt über die zweite Schwenkvorrichtung 13 zur zweiten Strangformungsvorrichtung 7.The paper web 1a passes via the first pivoting plate 6 and the gluing device 5 to the first rope-forming device 14 and the second paper web 1b via the spreading device 4 and the second pivoting plate 13 to the second rope-forming device 7. The inner paper webs are fed through the from the second reel 8 withdrawn sheet material, which is withdrawn by the second material pull cutting device and correspondingly cut into the paper webs 8a, 8b, is also conveyed via the third and fourth material run to the two strand forming devices 14, 7. The paper web 8a passes via the spreading device 11 to the first pivoting plate 6 and from there into the first strand-forming device 14. The second paper web 8b passes via the second pivoting device 13 to the second strand-forming device 7.

Die Zugspannungen der Papierbahnen werden wie folgt gesteuert bzw. geregelt. Die beiden Papierbahnen 8a, 8b werden über den Tänzer 10 gesteuert bzw. eingestellt. Die Zugspannung der Papierbahn 1a wird über den Tänzer 2 gesteuert und die Papierbahn 1b wird über den Tänzer 15 eingestellt beziehungsweise gesteuert.The tensions of the paper webs are controlled or regulated as follows. The two paper webs 8a, 8b are controlled or adjusted via the dancer 10. The tension of the paper web 1a is about the dancer 2 is controlled and the paper web 1b is set or controlled via the dancer 15.

Es ergeben sich dann zwei Stränge 20, 21, die außen Papierbahnen aus der Bobine 1 bzw. Bobinenvorrichtung 1 aufweisen und innen Papierbahnen aus der Bobine 8 bzw. Bobinenvorrichtung 8. Dies ist in Fig. 6 gut zu erkennen.This then results in two strands 20, 21, which have paper webs from the bobbin 1 or bobbin device 1 on the outside and paper webs from the bobbin 8 or bobbin device 8 on the inside. This is in 6 clearly visible.

Zur Änderung von der ersten Betriebsart auf die zweite Betriebsart oder andersherum müssen lediglich die Papierbahnen 1b und 8a in deren Lage geändert werden. Die Papierbahn 1b muss um den Tänzer 15 gelegt werden und so um Rollen gelegt werden, dass diese Bahn in Eingriff mit der zweiten Schwenkplatte 13 gelangt. Die Papierbahn 8a muss von der ersten Betriebsart in die zweite Betriebsart hinter der Spreizvorrichtung 11 so um Rollen gelegt werden, dass die Papierbahn 8a mit der ersten Schwenkvorrichtung 6 in Wirkverbindung gelangt. Somit ist eine sehr einfache Umstellung von einer ersten Betriebsart auf eine zweite Betriebsart und andersherum möglich.To change from the first operating mode to the second operating mode or vice versa, only the position of the paper webs 1b and 8a must be changed. The paper web 1b has to be wound around the dancer 15 and wound around rollers in such a way that this web comes into engagement with the second pivot plate 13. From the first mode of operation to the second mode of operation, the paper web 8a must be placed around rollers behind the spreading device 11 in such a way that the paper web 8a comes into operative connection with the first pivoting device 6 . A very simple changeover from a first operating mode to a second operating mode and vice versa is thus possible.
