Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines geformten Strangs aus einem Material der Tabak verarbeitenden Industrie, insbesondere aus Tabak oder Filtermaterial. Die Erfindung betrifft ferner eine Strangmaschine zur Herstellung eines Tabakstrangs oder eines Filterstrangs, mit einer Strangfördervorrichtung und einer Formatvorrichtung zur Formung des Strangs. Außerdem betrifft die Erfindung einen Einlauffinger einer Formatvorrichtung, insbesondere der Tabak verarbeitenden Industrie, sowie die Verwendung eines Druckluftstromes.The invention relates to a method for producing a molded strand of a material of the tobacco processing industry, in particular of tobacco or filter material. The invention further relates to a stranding machine for producing a tobacco rod or a filter strand, comprising a strand conveying device and a shaping device for shaping the strand. Moreover, the invention relates to an inlet finger of a format device, in particular the tobacco processing industry, as well as the use of a compressed air flow.

Aus der DE 42 25 644 A1 ist ein Teil einer Strangmaschine der Tabak verarbeitenden Industrie bekannt. Es ist insbesondere eine Vorrichtung zum Abstreifen von Tabakpartikein von einem Strangförderer einer Zigarettenstrangmaschine bei der Übergabe eines Tabakstrangs vom Strangförderer in eine Formatvorrichtung beschrieben. Tabak wird auf den Strangförderer, der als Saugstrangförderer ausgebildet Ist, aufgeschauert und in Richtung einer Formatvorrichtung geführt. Zur Übergabe in die Formatvorrichtung ist In der DE 42 25 644 A1 an einem Einiauffinger der Formatvorrichtung eine Abstrelfkante vorgesehen, die den Tabak bzw. den Tabakstrang vom Saugstrangförderer bzw. dem Saugstrangfördererband abkratzt, um so zu verhindern, dass Tabak an dem Saugband hängen blelbt. Auf eine ähnliche Art ist es auch möglich, einen Filterstrang herzustellen.From DE 42 25 644 A1 a part of a strand machine of the tobacco-processing industry is known. In particular, a device for stripping tobacco particles from a strand conveyor of a cigarette rod machine during the transfer of a tobacco rod from the strand conveyor into a format device is described. Tobacco is on the strand conveyor, which is designed as Saugstrangförderer Is, paused and led in the direction of a format device. In order to be transferred to the format device, DE 42 25 644 A1 discloses an abrading edge on a Einiauffinger the format device that scrapes the tobacco or tobacco rod from Saugstrangförderer or Saugstrangfördererband so as to prevent tobacco hanging on the suction belt bled. In a similar way it is also possible to make a filter strand.

Es hat sich nun gezeigt, dass bei der Strangherstellung und Insbesondere bei dem Einlauffinger der Formatvorrichtung und dort speziell an der Übergabestelle von dem Saugstrangförderer bzw, dem Strangförderer in die Formatvorrichtung einzelne Fasern dem Saugband folgen und nicht wie gewünscht über den Einlauffinger in die Formatvorrichtung einlaufen. Es kann außerdem geschehen, dass sich mit der Zeit mehrere Fasern am Finger ansammeln und dann eine Art Knäuel mit gerissen wird. Hierdurch entsteht ein unregelmäßiger Strangaufbau. Ein zu großes Knäuel kann außerdem zu einem Strangbruch und somit zu einem Maschlnenstopp führen.It has now been shown that in strand production and in particular in the inlet finger of the format device and there especially at the transfer point of the Saugstrangförderer or the strand conveyor in the formatting device individual fibers follow the suction belt and do not run as desired on the inlet finger in the format device. It can also happen that over time, several fibers accumulate on the finger and then a kind of ball is torn with. This creates an irregular strand structure. Too large a ball can also lead to a strand break and thus to a Maschlnenstopp.

Es ist Aufgabe der vorllegenden Erfindung, die gattungsgemäße Vorrichtung und ein gattungsgemäßes Verfahren zu verbessern. Insbesondere soll verhindert werden, dass das Material, das von der Materialfördervorrichtung zur Formatvorrichtung transportiert wird, nicht vollständig übergeben wird.It is an object of the present invention to improve the generic device and a generic method. In particular, it should be prevented that the material that is transported from the material conveying device to the format device is not completely handed over.

Gelöst wird diese Aufgabe durch ein Verfahren zur Herstellung eines geformten Strangs aus einem Material der Tabak verarbeitenden Industrie, insbesondere aus Tabak oder Filtermaterial, mit den folgenden Verfahrensschritten:

  • Bilden eines Strangs auf einer Fördervorrichtung,
  • Übergabe des Strangs von der Fördervorrichtung in eine Formatvorrichtung,
  • Formen des Strangs in der Formatvorrichtung, wobei bei dem Schritt der Übergabe des Strangs ein Druckluftstrom vorgesehen ist.
This object is achieved by a method for producing a molded strand from a material of the tobacco-processing industry, in particular from tobacco or filter material, with the following process steps:
  • Forming a strand on a conveyor,
  • Transfer of the strand from the conveyor into a format device,
  • Forming the strand in the format device, wherein in the step of transferring the strand, a compressed air flow is provided.

Erfindungsgemäß wurde festgestellt, dass der Druckluftstrom die Ablösung des Strangs von der Fördervorrichtung und die Übergabe in die Formatvorrichtung unterstützt. Durch das gezielte Einbringen von Druckluft bei der Übergabe des Strangs lässt sich verhindern, dass Fasern mit der Fördervorrichtung mitgerissen werden und dass es zu Störungen kommt.According to the invention it has been found that the compressed air flow supports the detachment of the strand from the conveying device and the transfer to the format device. The targeted introduction of compressed air during the transfer of the strand can be prevented that fibers are entrained with the conveyor and that it comes to interference.

Vorzugsweise ist die Menge und die Richtung des Druckluftstromes vorgebbar und/oder einstellbar. Hierdurch kann die Übergabe des Strangs noch weiter optimiert werden. Wenn der Druckluftstrom wenigstens teilweise in eine Ablöserichtung des Strangs von der Fördervorrichtung gerichtet, ist bzw. bläst, wird die Übergabe, insbesondere bei einem Saugstrangförderer als Fördervorrichtung, besonders effizient ermöglicht.Preferably, the amount and the direction of the compressed air flow can be predetermined and / or adjusted. As a result, the transfer of the strand can be further optimized. When the compressed air flow is directed or blown at least partially in a detachment direction of the strand from the conveying device, the transfer, in particular in the case of a suction strand conveyor as conveying device, is rendered particularly efficient.

Wenn der Druckluftstrom auf einen Einlauffinger der Formatvorrichtung und/oder auf die Fördervorrichtung gerichtet ist, kann sehr effektiv verhindert werden, dass sich auf dem Einlauffinger oder der Fördervorrichtung entsprechendes Material ansammelt. Vorzugsweise ist der Druckluftstrom gegen die Förderrichtung des Strangs gerichtet. Im Rahmen dieser Erfindung bedeutet gegen die Förderrichtung auch schräg gegen die Förderrichtung bzw. teilweise entgegen der Förderrichtung. Bei einem Saugbandförderer als Fördervorrichtung ist die Richtung des Druckluftstroms vorzugswelse schräg bzw. quer entgegen der Saugrichtung.If the compressed air flow is directed to an inlet finger of the format device and / or on the conveyor, can be very effectively prevented that accumulates on the inlet finger or the conveyor corresponding material. Preferably, the compressed air flow is directed against the conveying direction of the strand. In the context of this invention means against the conveying direction also obliquely against the conveying direction or partially against the conveying direction. In a suction belt conveyor as a conveying device, the direction of the compressed air flow is preferred obliquely or transversely opposite to the suction direction.

In einer besonders bevorzugten Ausführungsform, die elgenständigen erfinderischen Charakter aufweist, wird der Druckluftstrom durch einen Einlauffinger der Formatvorrichtung geleitet. Hierdurch kann ein sehr kleinbauender Übergabebereich realisiert werden, was schließlich zu einer kleinen Strangmaschine und einer effizienten Verfahrensführung führt.In a particularly preferred embodiment, the Elgenständigen inventive character, the compressed air stream is passed through an inlet finger of the format device. As a result, a very small-sized transfer area can be realized, which ultimately leads to a small strand machine and an efficient process management.

Die Aufgabe wird ferner durch eine Strangmaschine, Insbesondere der Tabak verarbeitenden Industrie, zur Herstellung eines Tabakstrangs oder eines Filterstrangs, mit einer Strangfördervorrichtung und einer Formatvorrichtung zur Formung des Strangs gelöst, wobei im Bereich der Übergabe des Strangs von der Strangfördervorrichtung auf die Formatvorrichtung eine Vorrichtung zur Zuführung von Druckluft in den Übergabebereich vorgesehen ist. Hierbei bläst die Druckluft direkt an einem Übergabebereich auf das Strangmaterial, so dass sich keine Fasern im Übergabebereich ablagern können. Die Vorrichtung zur Zuführung von Druckluft wird im Rahmen der Erfindung auch Druckluftzuführungsvorrichtung genannt.The object is further achieved by a stranding machine, in particular the tobacco processing industry, for producing a tobacco rod or a filter strand, with a strand conveying device and a format device for forming the strand, wherein in the area of transfer of the strand from the strand conveying device to the format device, a device for Supply of compressed air is provided in the transfer area. Here, the compressed air blows directly on a transfer area on the strand material, so that no fibers can deposit in the transfer area. The device for supplying compressed air is called in the invention also compressed air supply device.

Die Zuführung von Druckluft ist sehr definiert, wenn die Druckluftzuführungsvorrichtung in Druckluftförderrichtung stromabwärts eine Düse umfasst. Die Düse Ist vorzugsweise eine Schiltzdüse, die sich weiter vorzugsweise über die Breite des Strangs erstreckt. Vorzugsweise hat die Schlltzdüse eine Höhe von wenigen Zehntel Millimetern und eine Breite von fünf bis zehn Millimetern, insbesondere vorzugsweise ca. acht Millimeter. Eine besonders bevorzugte Ausführungsform ist dann gegeben, wenn die Druckluftzuführungsvorrichtung ausgestaltet ist, um einen Druckluftstrom auf eine Schaberkante oder eine Abstreifkante eines Einlauffingers der Formatvorrichtung zu richten. Durch diese Ausgestaltung können sich keine Faserknäuel am Elnlauffinger bilden, so dass ein regelmäßiger Strangaufbau ermöglicht ist. Vorzugsweise ist die Druckluftzuführungsvorrichtung ausgestaltet, um einen Druckluftstrom auf die Strangfördervorrichtung oder einen auf der Strangfördervorrichtung geförderten Strang zu richten, wobei die Richtung teilweise In eine Ablöserichtung des Strangs von der Strangfördervorrichtung und/oder quer zur und Insbesondere quer gegen die Strangfördervorrichtung ist, Die Druckluft ist insbesondere auf den Strang bzw. das Strangmaterial gerichtet.The supply of compressed air is very defined when the compressed air supply device in the compressed air conveying direction downstream comprises a nozzle. The nozzle is preferably a Schiltzdüse, which further preferably extends across the width of the strand. Preferably, the Schlltzdüse has a height of a few tenths of a millimeter and a width of five to ten millimeters, more preferably preferably about eight millimeters. A particularly preferred embodiment is provided when the compressed air supply device is designed to direct a stream of compressed air onto a scraper edge or a scraping edge of an infeed finger of the format device. By this configuration, no Make fiber balls on the runner finger, so that a regular strand construction is possible. Preferably, the compressed air supply device is configured to direct a stream of compressed air to the strand conveyor or a strand conveyed on the strand conveyor, the direction being partially in a direction of separation of the strand from the strand conveying device and / or across and especially against the strand conveying device, which is compressed air directed in particular to the strand or the strand material.

Die Aufgabe wird ferner durch einen Einlauffinger einer Formatvorrichtung, insbesondere der Tabak verarbeitenden Industrie gelöst, der eine Bohrung zur Förderung von Druckluft umfasst. Durch den erfindungsgemäßen Einlauffinger ist es auf elegante und kosteneffiziente Weise möglich, Druckluft in den Bereich der Übergabe des Strangs von einer Strangfördervorrichtung zu der Formatvorrichtung zu fördern. Vorzugsweise endet die Bohrung In einer Düse, die in der Nähe einer Abstreifkante des Einlauffingers angeordnet ist. In einer besonders effizienten Ausgestaltung des Einlauffingers ist die aus der Düse austretende Druckluft auf die Abstreifkante und/oder auf eine Fördervorrichtung gegenüber der Abstreifkante gerichtet.The object is further achieved by an inlet finger of a format device, in particular the tobacco processing industry, comprising a bore for conveying compressed air. The inlet finger according to the invention makes it possible in an elegant and cost-efficient manner to convey compressed air into the region of transfer of the strand from a strand conveying device to the forming device. Preferably, the bore terminates in a nozzle located proximate a wiper edge of the run-in finger. In a particularly efficient embodiment of the inlet finger, the compressed air emerging from the nozzle is directed towards the wiping edge and / or onto a conveying device relative to the wiping edge.

Schließlich wird die Aufgabe durch die Verwendung eines Druckluftstroms im Bereich einer Übergabe von Material von einer Materialfördervorrichtung zu einer Formatvorrichtung, insbesondere der Tabak verarbeltenden Industrie, gelöst. Eine besonders hohe Effizienz ist dann gegeben, wenn der Druckluftstrom auf einen Einlauffinger der Formatvorrichtung und/oder auf die Materialfördervorrichtung gerichtet ist. Vorzugsweise ist die Richtung des Druckluftstroms wenigstens teilweise in einer Ablöserichtung des Materials von der Materialfördervorrichtung. Die Richtung des Druckluftstroms ist damit insbesondere quer zur Förderrichtung des Strangs. Vorzugsweise ist die Richtung des Druckluftstroms teilweise entgegen der Förderrichtung des Materials auf der Materialfördervorrichtung. Unter teilweise entgegen wird im Rahmen der Erfindung auch schräg bzw. quer gegen die Förderrichtung des Materials auf der Materialförderbahn verstanden.Finally, the object is achieved by the use of a stream of compressed air in the area of a transfer of material from a material conveying device to a format device, in particular the tobacco processing industry. A particularly high efficiency is given when the compressed air stream is directed to an inlet finger of the format device and / or on the material conveying device. Preferably, the direction of compressed air flow is at least partially in a direction of separation of the material from the material delivery device. The direction of the compressed air flow is thus in particular transversely to the conveying direction of the strand. Preferably the direction of the compressed air flow is partially counter to the conveying direction of the material on the material conveying device. Under partially counteracting is understood in the context of the invention also obliquely or transversely to the conveying direction of the material on the material conveying path.

Die Technik derartiger Maschinen ist hinlänglich bekannt, so dass eine nähere Darstellung und Beschreibung hier nicht erforderlich ist.In Elnlaufkonus 13, along the strand guide surface 12 and in the strand channel 14 a circulating in the direction of arrow 16 format strip 17 is guided, which carries a wrapping material strip 18 through the formatting device 4. The technique of such machines is well known, so that a closer representation and description is not required here.

Im Bereich des Einlaufkonus 13 konvergiert der Saugstrangförderer 3 zur Strangführungsfläche des Formatbetts 6 und legt den In einer nicht dargestellten Strangaufbauzone aufgeschauerten und In üblicher Weise egalisierten Tabakstrang auf den durch die Formateinrichtung 4 bewegten Hüllmaterlalstreifen 18 auf. Dabei wird der Tabakstrang bei seiner Passage durch den Einlaufkonus 13 unter der Wirkung des Saugstrangförderers 3 stark komprimiert und entsprechend der Querschnittsveränderung des Einlaufkonus in Förderrichtung 16 des Formatbandes 17 so verformt, dass er in den teilweise von der Strangführungsfläche 12 des Formatbettes 6 umschlossenen Strangkanal einlaufen kann. Im Bereich der Strangführungsfläche 12 ist dem Formatbett 6 benachbart als weiteres Strangführungsmittel der Einlauffinger 7 mit einem Schaber 27 angeordnet, der zusammen mit der Strangführungsfläche 12 des Formatbettes 6 eine den Faserstrang 40, der In Fig. 1 nicht dargestellt ist, aber in Fig. 4, weiter komprlmierende und formende Strangführung bildet.In the region of the inlet cone 13, the suction strand conveyor 3 converges to the strand guide surface of the format bed 6 and places the tobacco strand, which has been stopped in a strand construction zone (not shown) and leveled in the usual manner, onto the skin material strip 18 moved by the format device 4. The tobacco rod is strongly compressed during its passage through the inlet cone 13 under the action of Saugstrangförderers 3 and deformed according to the change in cross section of the inlet cone in the conveying direction 16 of the format strip 17 so that it can run into the partially enclosed by the strand guide surface 12 of the format bed 6 strand channel , In the area of the strand guiding surface 12, the infeed finger 7 is arranged adjacent to the format bed 6 as a further strand guiding means with a scraper 27, the one together with the strand guide surface 12 of the format bed 6, a fiber strand 40, which is not shown in Fig. 1, but in Fig. 4, further Komprlmierende and forming strand guide forms.

Der Schaber 27 ist mittels Schrauben 28 oder anderer geeigneter Befestigungsmittel stirnseitig am Einlauffinger 7 der Formatvorrichtung 4 befestigt. Er besteht aus einem Grundkörper 19, dessen Unterseite als Strangführungsfläche 21 ausgebildet ist und in Einbauposition des Schabers der Strangführungsfläche 12 des Formatbettes 6 gegenüberliegt, so dass beide Strangführungsflächen 12 und 21 einen Strangführungskanal 22 einschließen. Die Strangführungsfläche 21 ist dazu konkav gewölbt und fluchtet mit einer Strangführungsfläche 23, die an der Unterseite des Einlauffingers 7 ausgebildet ist. Diese Ausbildung der Strangführungsflächen bewirkt in bekannter Weise das Verformen des ankommenden Tabakstrangs zu einem zylindrischen Faserstrang bei gleichzeitiger Umhüllung des Faserstrangs mit dem Hüllmaterialstreifen 18.The scraper 27 is fastened by means of screws 28 or other suitable fastening means on the front side of the inlet finger 7 of the format device 4. It consists of a base body 19 whose underside is designed as a strand guide surface 21 and in the installed position of the scraper of the strand guide surface 12 of the format bed 6 is opposite, so that both strand guide surfaces 12 and 21 include a strand guide channel 22. The strand guide surface 21 is curved concavely thereto and is aligned with a strand guide surface 23 which is formed on the underside of the inlet finger 7. This formation of the strand guide surfaces causes in a known manner, the deformation of the incoming tobacco rod to a cylindrical fiber strand with simultaneous wrapping of the fiber strand with the Hüllmaterialstreifen 18th

Der Schaber 27 und der Einlauffinger 7 können aus zwei oder mehr Teilen gefertigt sein, sie können aber auch einstückig ausgebildet sein. Der Einlauffinger 7 bzw. der Schaber 27 dienen Im Bereich der Abstreifkante 26, die in Fig. 2 besser dargestellt ist und am Einlaufende 24 des Einlauffingers 7 bzw. Schabers 27 angeordnet ist, dazu, das Fasermaterial von dem Saugstrangförderer 3 abzulösen. Ohne weitere Maßnahmen kann es dazu kommen, dass nicht sämtliche Fasern vom Saugstrangförderer 3 abgelöst werden, so dass diese zum einem an dem Saugstrangförderer oder zum anderen an der Abstreifkante 26 des Einlauffingers 7 bzw. Schabers 27 hängen bleiben können und dort Knäuel bilden. Dieses kann dann zu Unregelmäßigkeiten Im Strangaufbau führen. Hier schafft die Erfindung Aphilfe, indem Druckluft in Form eines Druckluftstroms 31 auf das Strangmaterial gerichtet wird, und zwar wie in Fig. 1 dargestellt ist, von schräg oben, also quer zur Ablöserichtung 41 des Strangmaterials von dem Saugstrangförderer 3. Die Druckluft kann hierbei zum einen auf den Einlauffinger 7 bzw. den Schaber 27 oder die Abstreifkante 26 gerichtet sein und/oder auf den Saugstrangförderer 3.The scraper 27 and the inlet finger 7 may be made of two or more parts, but they may also be integrally formed. In the region of the scraping edge 26, which is better represented in FIG. 2 and is arranged at the inlet end 24 of the inlet finger 7 or scraper 27, the inlet finger 7 and the scraper 27 serve to detach the fiber material from the suction strand conveyor 3. Without further measures, it may happen that not all fibers are detached from the suction belt conveyor 3, so that they can get stuck to one on the suction belt conveyor or the other on the wiper edge 26 of the inlet finger 7 or scraper 27 and form there balls. This can then lead to irregularities in the strand structure. Here, the invention provides Aphilfe by compressed air in the form of a compressed air stream 31 is directed to the strand material, and as shown in Fig. 1, obliquely from above, ie transversely to the detachment direction 41 of the strand material of the suction belt conveyor 3. The compressed air can be directed to the inlet finger 7 or the scraper 27 or the stripping edge 26 and / or on the Saugstrangförderer third

In Fig. 2, die eine vergrößerte Darstellung des Bereichs B aus Fig. 1 ist, ist insbesondere eine Vorrichtung dargestellt, die die Druckluft leitet. Hierbei handelt es sich um ein Druckluftrohr 30, an das eine Druckluftleitung 32 angeschlossen ist, wobei Druckluft durch eine Pumpe 33 erzeugt wird und in die Druckluftleitung 32 und anschließend das Druckluftrohr 30 gefördert wird. Der sich bildende Druckluftstrom 31 wird aus der Düse 35 heraus geblasen und streift an der Oberseite der Abstreifkante 26 etwaige gebildete Fasern des Strangmaterials ab und bringt diese wieder zum Strang.In Fig. 2, which is an enlarged view of the area B of Fig. 1, in particular, a device is shown, which directs the compressed air. This is a compressed air pipe 30, to which a compressed air line 32 is connected, wherein compressed air is generated by a pump 33 and in the compressed air line 32 and then the compressed air pipe 30 is conveyed. The forming compressed air stream 31 is blown out of the nozzle 35 and strips at the top of the scraping edge 26 any fibers of the strand material formed and brings them back to the strand.

Im Rahmen der Erfindung kann anstelle von Tabakfasern auch Flltermaterial, wie Filterfasern, Verwendung finden. Sofern also von Tabak oder Tabakfasern bzw. Tabakstrang die Rede ist, gilt die hierzu vorgenommene Offenbarung auch für Filtermaterial, Filterfasern bzw. Filterstränge. Hierbei sei insbesondere an relativ kurze Fasern mit einer Länge von drei bis sechs Millimetern gedacht, die mehrere Komponenten umfassen können. So können Bikomponentenfasern Verwendung finden, die einen Kern aus einem bei einer höheren Temperatur schmeizenden Material aufweisen als die Hüllen, so dass nach anschließendem Erhitzen ein entsprechend guter Faserverbund erzeugt werden kann. Hierzu sei auf die Patentanmeldung DE 102 17 410 A1 der Anmelderin verwiesen, die vollumfänglich in die Offenbarung der vorliegenden Patentanmeldung aufgenommen sein soll.In the context of the invention, instead of tobacco fibers, it is also possible to use filler material, such as filter fibers. So far as tobacco or tobacco fibers or tobacco rod is mentioned, the disclosure made for this also applies to filter material, filter fibers or filter strands. In this case, it is particularly intended to relatively short fibers with a length of three to six millimeters, which may include several components. Thus, bicomponent fibers can be used which have a core made of a material which has a higher temperature than the sheaths, so that a correspondingly good fiber composite can be produced after subsequent heating. For this purpose, reference is made to the patent application DE 102 17 410 A1 of the Applicant, which should be incorporated in full in the disclosure of the present patent application.

Fig. 3 zeigt eine schematische Schnittdarstellung einer bevorzugten Ausführungsform, Insbesondere zur Herstellung eines Vilesfilterstrangs. Die meisten Komponenten entsprechen denen aus den Figuren 1 und 2. Im Unterschied zu den bisherigen Ausführungsformen wird die Druckluft in der Ausführungsform gemäß Fig. 3 durch Bohrungen 34 Im Einlauffinger 7 zu einer Düse 35, die im Bereich der Abstreifkante 26 angeordnet ist, geleitet. Die Bohrung 34 bzw. die Bohrungen 34 hat bzw. haben vor der Düse vorzugsweise einen Durchmesser von ca. drei bis fünf Millimetern. Die Düse selber hat eine Höhe von einigen Zehntel Millimetern und eine Breite von ca. acht Millimetern. Durch diese Ausführungsform mit einer Bohrung 34 im Einlauffinger 7, insbesondere in der Nähe der Abstrelfkante 26, ist es sehr effizient möglich, einen Tabakstrang oder einen Filterstrang zu bilden.Fig. 3 shows a schematic sectional view of a preferred embodiment, in particular for the production of a Vilesfilterstrangs. Most components correspond to those of Figures 1 and 2. In contrast to the previous embodiments, the compressed air in the embodiment of FIG. 3 through holes 34 in the inlet finger 7 to a nozzle 35, which is arranged in the region of the scraper edge 26, passed. The bore 34 or the bores 34 has or preferably have a diameter of approximately three to five millimeters in front of the nozzle. The nozzle itself has a height of a few tenths of a millimeter and a width of about eight millimeters. By this embodiment with a bore 34 in the inlet finger 7, in particular in the vicinity of the Abstrelfkante 26, it is very efficiently possible to form a tobacco rod or a filter strand.

Fig. 4 zeigt eine vergrößerte schematische Darstellung der Ausführungsform aus Fig. 3. In dieser Fig. sind für die bessere Darstellung die Druckluftpfelle 31 weggelassen worden, so dass die Düse 35 besser erkennbar ist. In diesem Ausführungsbeispiel bzw. dieser Fig. ist auch der Faserstrang 40 angedeutet. Es ist möglich, den Druckluftstrom sehr definiert bezüglich der Richtung und der Stärke einzustellen.Fig. 4 shows an enlarged schematic representation of the embodiment of Fig. 3. In this figure, the compressed air level 31 have been omitted for better representation, so that the nozzle 35 is better recognizable. In this embodiment or this Fig. Also, the fiber strand 40 is indicated. It is possible to set the compressed air flow very defined with respect to the direction and the strength.

Durch das gezielte Einbringen von Druckluft In den Übergabebereich lässt sich verhindern, dass Fasern mit dem Saugband mitgerissen werden und zu Störungen führen können. Die Luft wird durch den Formateinlauffinger hindurch geleitet und bläst direkt an der Übergabestelle auf das Strangmaterial. Es können sich so keine Fasern mehr im Übergabebereich ablagern, was zu einer verbesserten Strangbildung führt.The targeted introduction of compressed air In the transfer area, fibers can be prevented from being entrained with the suction belt and causing problems. The air is passed through the format inlet finger and blows directly onto the strand material at the transfer point. It can no longer deposit fibers in the transfer area, resulting in improved strand formation.
