Description

Die vorliegende Erfindung betrifft eine Zigaretten-Filterhülse sowie ein Verfahren zur Herstellung einer Zigaretten-Filterhülse. Insbesondere bei der Selbstverfertigung von Zigaretten durch den Verbraucher mit einfachen oder komplexeren Selbstverfertigungsgeräten werden solche Zigaretten-Filterhülsen verwendet. Die Filterhülsen umfassen ein Filterstück und eine Zigarettenpapierhülse, wobei zumindest das Filterstück mit einem Filterbelagpapier umgeben ist. Die Filterhülse bildet eine hohle Röhre zur Aufnahme von Tabak.The present invention relates to a cigarette filter sleeve and a method for producing a cigarette filter sleeve. In particular, in the self-production of cigarettes by the consumer with simple or complex self-production devices such cigarette filter sleeves are used. The filter sleeves comprise a filter piece and a cigarette paper sleeve, wherein at least the filter piece is surrounded by a filter cover paper. The filter sleeve forms a hollow tube for receiving tobacco.

Die DE 42 06 509 A1 offenbart eine Zigarettenpapierhülse mit Filtermundstück zur Selbstverfertigung von Zigaretten, wobei in der Papierhülse ein weiterer Filterpfropfen vorgesehen ist, dessen Durchmesser dem der Papierhülse derart angepasst ist, dass der weitere Filterpfropfen an der Innenfläche der Papierhülse dicht anliegt, aber durch leichten Druck beim Befüllen der Papierhülse mit einer Tabakportion in dieser axial verschiebbar ist. Ferner offenbart die DE 42 06 509 A1 ein Verfahren zur Herstellung einer derartigen Zigarettenpapierhülse, bei der der weitere Filterpfropfen in dem Filtermundstück entgegengesetzten Ende der Papierhülse angeordnet ist, wobei ein Strang von Zigarettenhülsenpapier mit nacheinander angeordneten mit der Papierhülse verklebten Filterstäben und unverklebten Filterstäben hergestellt wird. Die Filterstäbe haben dabei die doppelte Länge der gewünschten Filterpfropfen der fertigen Zigarettenpapierhülse. Jeweils in der Mitte der verklebten Filtermundstäbe und der verschiebbaren Filterstäbe wird durchschnitten.The DE 42 06 509 A1 discloses a cigarette paper tube with filter mouthpiece for self-production of cigarettes, wherein in the paper sleeve another filter plug is provided whose diameter is adapted to the paper sleeve so that the further filter plug on the inner surface of the paper sleeve is tight, but by light pressure when filling the paper tube with a tobacco portion is axially displaceable in this. Further, the DE 42 06 509 A1 a method for producing such a cigarette paper tube, wherein the further Filterpfropfen is arranged in the filter mouthpiece opposite end of the paper tube, wherein a strand of cigarette tube paper with successively arranged with the paper sleeve bonded filter rods and unverklebten filter rods is produced. The filter rods have twice the length of the desired filter plug of the finished cigarette paper tube. In each case in the middle of the glued filter mouth bars and the sliding filter rods is cut.

Die CA 2 211 571 A offenbart eine Zigaretten-Filterhülse mit innen und außen angebrachten Endenstützen.The CA 2 211 571 A discloses a cigarette filter sleeve with internally and externally mounted end supports.

Die DE 34 07 461 C1 offenbart ein Tabakerzeugnis für die Selbstverfertigung einer Zigarette bzw. einer Filter-Zigarette. Zum erleichterten Einführen des vorgefertigten formstabilen Tabakstrangs in eine vorgefertigte Zigarettenpapierhülse dient eine trichterartige Hülse, die mit ihrem Ende kleineren Durchmessers an die stirnseitige Öffnung der Zigarettenpapierhülse ansetzbar ist.The DE 34 07 461 C1 discloses a tobacco product for the self-production of a cigarette or a filter cigarette. For easier insertion of the prefabricated dimensionally stable tobacco rod in a prefabricated cigarette paper tube is a funnel-like sleeve which is attachable with its end of smaller diameter to the frontal opening of the cigarette paper tube.

Die DE 42 07 769 A1 offenbart ein Tabakerzeugnis für die Selbstverfertigung einer Zigarette. An einem stirnseitigen Ende einer Tabakportion ist ein Tabak-Konditionierelement entsprechend einem Filterstück angesetzt, welches nach Überführung der Tabakportion in einen Tabakaufnahmeraum einer Zigarettenpapierhülse aus diesem vorstehend von der Tabakportion abbrechbar ist.The DE 42 07 769 A1 discloses a tobacco product for the self-production of a cigarette. At a front end of a tobacco portion, a tobacco conditioning element is attached according to a filter piece, which is breakable after transferring the tobacco portion into a tobacco receiving space of a cigarette paper tube from the above of the tobacco portion.

Ein Problem bei der Einfüllung von Tabak in die Filterhülse beruht oft auf Deformationen der Papierhülse. In den meisten Fällen muss das offene Ende der Papierhülse über eine Befüllungshilfe geschoben werden, die nur einen etwas geringeren Durchmesser hat als die Papierhülse an ihrer Innenseite. Außerdem entsteht oft ein Problem dadurch, dass die dünne und leicht verformbare Papierhülse während des Tabak-Einfüllvorgangs gehalten werden muss. Dieses Problem wird bei automatisierten Befüllungen im Rahmen der Selbstverfertigung noch kritischer, weil der Verwender dabei oftmals keine Möglichkeit hat, die Papierhülse innerhalb des Gerätes zu stützen oder gerade zu richten.A problem with the filling of tobacco into the filter sleeve is often due to deformations of the paper tube. In most cases, the open end of the paper tube must be pushed over a filling aid that is only slightly smaller in diameter than the paper tube on its inside. In addition, a problem often arises in that the thin and easily deformable paper tube must be held during the tobacco filling process. This problem is even more critical in automated filling in the context of self-production, because the user often has no way to support the paper sleeve within the device or just to judge.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Zigaretten-Filterhülse sowie ein Verfahren zur Herstellung einer Zigaretten-Filterhülse bereitzustellen, welche die oben angesprochenen Probleme des Standes der Technik überwinden. Insbesondere soll eine zuverlässig praktikable Befüllung einer Zigaretten-Filterhülse mit Tabak gewährleistet werden.It is an object of the present invention to provide a cigarette filter sleeve and a method for producing a cigarette filter sleeve, which overcome the above-mentioned problems of the prior art. In particular, a reliable practicable filling a cigarette filter sleeve with tobacco to be guaranteed.

Diese Aufgabe wird erfindungsgemäß im Hinblick auf die Zigaretten-Filterhülse dadurch gelöst, dass im Bereich des Papierhülsenendes, das dem Filterstück gegenüberliegt, eine Endenstütze angebracht ist, die innen und/oder außen zumindest teilumfänglich an der Papierhülse vorgesehen ist.This object is achieved with regard to the cigarette filter sleeve, characterized in that in the region of the paper sleeve end, which faces the filter piece, an end support is attached, which is provided inside and / or outside at least partially on the paper sleeve.

Eine solche Endenstütze kann direkt am Papierhülsenende oder auch etwas weiter zur Filterseite versetzt angebracht sein, solange sie ihre Stützfunktion auf den Endbereich erstreckt und damit auch die Form des offenen Papierhülsenendes im Wesentlichen aufrechterhalten kann.Such an end support may be mounted directly on the paper sleeve end or slightly offset further to the filter side as long as it extends its support function to the end region and thus can substantially maintain the shape of the open paper sleeve end as well.

Die erfindungsgemäße Ausgestaltung mit einer Endenstütze im Bereich des Papierhülsenendes macht das Befüllen der Papierhülse mit Tabak in jedem Falle möglich und erleichtert es in vielen Fällen, weil die Formintegrität der ZigarettenPapierhülse besonders an kritischen Stellen gewährleistet wird. Die Abstützung im Bereich des Papierhülsenendes wirkt sich aber nicht nur auf die Formerhaltung an diesem Ende aus sondern trägt auch dazu bei, dass die Papierhülse ihre Form über die gesamte Länge leichter behält, so dass sich der Tabak beim Einfüllen gleichmäßig und gut verteilen kann. Einerseits sorgt die Erfindung also dafür, dass Zigaretten zuverlässig und insbesondere auch mit Hilfe von Selbstverfertigungsgeräten reproduzierbar befüllt werden können, andererseits wird die Qualität der so befüllten Zigaretten sichergestellt.The inventive design with an end support in the paper sleeve end makes filling the paper tube with tobacco in any case possible and makes it easier in many cases, because the shape integrity of cigarette paper sleeve is guaranteed especially at critical points. However, the support in the paper sleeve end not only affects the shape retention at this end but also helps to ensure that the paper tube retains its shape more easily over the entire length, so that the tobacco can distribute evenly and well during filling. On the one hand, the invention thus ensures that cigarettes can be filled reliably and in particular reproducibly with the help of self-production devices, on the other hand, the quality of the so-filled cigarettes is ensured.

Die Endenstütze kann zumindest teilweise überlappend über dem offenen Endabschnitt oder in dem offenen Endabschnitt des Papierhülsenendes liegen. Es spricht auch nichts dagegen, eine Endenstütze mit einem direkten, stirnseitigen Anschluss an das Papierhülsenende auszubilden. Bei überlappender oder teilweise überlappender Anordnung dürfte sich allerdings die Stabilität erhöhen, während eine stirnendige Abstützung die Länge des Hülsenkörpers, die zur Befüllung zur Verfügung steht, nicht beeinträchtigt.The end support may be at least partially overlapping over the open end portion or in the open end portion of the paper tube end. There is nothing wrong with forming an end support with a direct, frontal connection to the paper sleeve end. In the case of an overlapping or partially overlapping arrangement, however, the stability is likely to increase, while an end-end support does not impair the length of the sleeve body which is available for filling.

Die Endenstütze ist als Ring ausgebildet sein, insbesondere einen, vorzugsweise geschlossenen, Papierring oder Filterbelagpapier-Ring aufweisen. Das Applizieren von Materialien wie Papierringen oder Filterbelagpapier-Ringen ist in einfacher Weise durchführbar, beispielsweise durch Rollen und eine Verklebung. Es können aber auch etwas festere Materialien wie beispielsweise Kartonmaterialien oder verstärkte Papiermaterialien verwendet werden - auch Kunststoffe sind grundsätzlich denkbar.The end support is designed as a ring, in particular have a, preferably closed, paper ring or filter cover paper ring. The application of materials such as paper rings or filter cover paper rings can be carried out in a simple manner, for example by rolling and gluing. But it can also be something firmer materials such as cardboard materials or Reinforced paper materials are used - even plastics are conceivable in principle.

Bei einer bevorzugten Ausführungsform der Zigaretten-Filterhülse weist die Endenstütze ein Innenstützelement auf. Sie kann natürlich auch lediglich aus einem solchen Innenstützelement bestehen, das - wie der Name sagt - die ZigarettenPapierhülse von innen stützt, also in das offene Papierhülsenende über eine gewisse Strecke eindringt. Natürlich ist eine Abstützung von innen besonders effektiv, und sie kann gemäß einer besonders bevorzugten Ausführungsform mit Hilfe eines Stützfilterstücks realisiert werden. Mit anderen Worten wird als Material für die Endenstütze eines verwendet, welches ohnehin im Fertigungsprozess zur Verfügung steht, nämlich ein Filtermaterial bzw. ein Filterpfropfen, wie er auch auf der anderen Seite der Filterhülse verwendet wird. Der zur inneren Abstützung verwendete Filterpfropfen muss nicht dieselbe große Länge haben wie das Filterstück selbst. Seine Verwendung macht die Herstellung insgesamt besonders effizient.In a preferred embodiment of the cigarette filter sleeve, the end support has an inner support element. Of course, it can also consist only of such an inner support element, which - as the name implies - supports the cigarette paper sleeve from the inside, ie penetrates into the open paper sleeve end over a certain distance. Of course, support from the inside is particularly effective, and according to a particularly preferred embodiment, it can be realized with the aid of a support filter piece. In other words, the material used for the end support is one which is available anyway in the production process, namely a filter material or a filter plug, as it is also used on the other side of the filter sleeve. The filter plug used for internal support need not be the same great length as the filter piece itself. Its use makes the overall production particularly efficient.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist die Filterhülse eine Kombination der oben genannten Stützmaßnahmen auf, wobei die Endenstütze ein innen im offenen Endabschnitt des Papierhülsenendes liegende Stützfilterstück und einen Papierring umfasst, der das Papierhülsenende im Bereich des Stützfilterstücks übergreift. Dabei kann das Stützfilterstück mit Hilfe des Papierrings in derselben Weise an der Filterpapierhülse befestigt werden, wie dies bei einem herkömmlichen Filter der Fall ist.According to an advantageous embodiment of the invention, the filter sleeve has a combination of the above-mentioned supporting measures, wherein the end support comprises a lying inside the open end portion of the paper sleeve end support filter piece and a paper ring which engages over the paper sleeve end in the region of the support filter piece. In this case, the support filter piece can be fixed by means of the paper ring in the same manner to the filter paper sleeve, as is the case with a conventional filter.

Das erfindungsgemäße Verfahren zur Herstellung einer Zigaretten-Filterhülse mit einem Filterstück und einer Zigarettenpapierhülse, wobei zumindest das Filterstück mit einem Filterbelagpapier umgeben ist, ist so ausgestaltet, dass

  • im Bereich des Papierhülsenendes, das dem Filterstück gegenüber liegt, eine Endenstütze angebracht wird, die innen und/oder außen zumindest teilumfänglich an der Papierhülse vorgesehen ist.
The inventive method for producing a cigarette filter sleeve with a filter piece and a cigarette paper tube, wherein at least the filter piece is surrounded with a filter cover paper, is designed such that
  • in the region of the paper sleeve end, which lies opposite the filter piece, an end support is provided, which is provided inside and / or outside at least partially on the paper sleeve.

Die Endenstütze weist bei dem erfindungsgemäßen Verfahreneinen Ring auf, wobei der Ring am Papierhülsenende angeklebt wird. Dabei und bei der allgemeinen Ausführungsform des erfindungsgemäßen Verfahrens sind natürlich entsprechend die oben schon beschriebenen Vorteile erzielbar.The end support has a ring in the method according to the invention, wherein the ring is adhered to the paper sleeve end. In this case and in the general embodiment of the method according to the invention, of course, the advantages already described above can be achieved.

Gemäß einer Verfahrensvariante wird die Zigaretten-Filterhülse aus einem Endlosstrang gefertigt, der eine insbesondere durchgehende Zigarettenpapier-Umhüllung aufweist und wiederkehrend der Länge nach die folgenden Elemente umfasst:

  • ein erstes Filterelement von doppelter Zigarettenfilterlänge,
  • einen leeren Papierhülsenabschnitt,
  • ein Endenstützelement mit der doppelten Länge einer Endenstütze, und
  • einen leeren Papierhülsenabschnitt.
According to a variant of the method, the cigarette filter sleeve is produced from a continuous strand which has a particularly continuous cigarette paper wrapper and comprises the following elements recurring lengthwise:
  • a first filter element of double cigarette filter length,
  • an empty paper tube section,
  • an end support member having twice the length of an end support, and
  • an empty paper tube section.

Die Herstellung von Zigarettenhülsen als Endlosstrang mit Filterelementen doppelter Länge ist bekannt und dieses Verfahren kann nun erfindungsgemäß abgewandelt werden, um Zigaretten-Filterhülsen mit Endenstützen bereitstellen zu können. Insbesondere gilt dies, wenn das Endenstützelement ein Stützfilterelement ist, und in diesem Fall wird bevorzugt ein Verfahren zur Herstellung von Zigarettenhülsen mit Endenstützen verwendet, bei dem

  • der Endlosstrang jeweils in der Mitte des Stützfilterstück-Elements getrennt wird, um Doppel-Zigarettenhülsen herzustellen, die an beiden freien Enden ein Stützfilterstück aufweisen,
  • eine Filterbelagpapier-Umhüllung, die mindestens so lang ist wie das erste Filterelement (aber auch etwas länger sein kann), um das erste Filterelement gelegt und dort befestigt wird,
  • die Doppel-Zigarettenhülsen in der Mitte der Filterbelagpapier-Umhüllung getrennt werden, um einzelne Zigarettenhülsen herzustellen, und bei dem
  • ein Papierring, der (etwas) länger ist als das Stützfilterstück, um das Stützfilterstück gelegt und dort befestigt wird, um einzelne Zigarettenhülsen mit Endenstützen herzustellen.
The production of cigarette tubes as a continuous strand with filter elements double length is known and this method can now be modified according to the invention to provide cigarette filter sleeves with end supports can. In particular, this applies when the end support member is a support filter element, and in this case, a method is preferably used for the production of cigarette tubes with end supports, in which
  • the endless strand is separated in each case in the middle of the supporting filter piece element in order to produce double cigarette tubes which have a supporting filter piece at both free ends,
  • a filter pad paper wrapper that is at least as long as the first filter element (but may be slightly longer) around which the first filter element is placed and secured there,
  • The twin cigarette tubes in the center of the filter cover paper cladding are separated to make individual cigarette tubes, and in which
  • a paper ring that is (slightly) longer than the support filter piece, placed around the support filter piece and fastened there to make individual cigarette tubes with end supports.

Der Papierring muss aber ganz allgemein nicht unbedingt länger sein als oder so lang sein wie das Stützfilterstück - er könnte beispielsweise als schmalerer Ring, speziell stirnseitig abschließend, über dem filterseitigen Ende des Stützfilterstücks liegen.In general, however, the paper ring does not necessarily have to be longer than or as long as the support filter piece - it could be, for example, as a narrower ring, especially on the front side, over the filter-side end of the support filter piece.

Die Abtrennung der Endenstütze kann in unterschiedlicher Art und Weise geschehen. Einerseits ist es möglich, das Stützfilterstück vor der Befüllung der Papierhülse mit Tabak vollständig von dem Papierring abzutrennen, so dass eine Zigarettenpapierhülse mit einem offenen Ende entsteht, die unmittelbar vor dem Einfüllen des Tabaks keine Endenstütze mehr aufweist. Die Erfindung zeigt ihre Wirkung in diesem Fall während des gesamten Handlings und Transportes der Zigarettenhülse bis vor der Befüllung. Eine Zigarettenhülse, die ihre Form bis zu diesem Zeitpunkt gewahrt hat, wird auch nach dem Abschneiden der gesamten Endenstütze ausreichend gut geformt sein, um eine einfache und gute Befüllung zu gewährleisten.The separation of the end support can be done in different ways. On the one hand, it is possible to completely separate the support filter piece from the paper ring before filling the paper tube with tobacco, so that a cigarette paper tube is formed with an open end, which has no end support immediately before filling the tobacco. The invention shows its effect in this case during the entire handling and transport of the cigarette tube until prior to filling. A cigarette tube, which has maintained its shape up to this time, will be sufficiently well shaped even after cutting the entire end support to ensure easy and good filling.

Andererseits kann die Endenstütze zunächst nur teilweise so abgeschnitten werden, dass die Befüllung durch das noch gestützte offene Ende möglich wird. Bei dieser Ausführungsform ist das erfindungsgemäße Verfahren so ausgestaltet, dass

  • von der Endenstütze einer Zigarettenhülse vor der Befüllung der Papierhülse mit Tabak zunächst das Stützfilterstück abgetrennt wird, worauf
  • der Tabak eingebracht wird, wobei der stehenbleibende Rest des Papierrings als Formstütze für das offene Ende dient, worauf
  • der stehenbleibende Rest des Papierrings abgetrennt wird.
On the other hand, the end support can initially only partially be cut so that the filling is possible through the still supported open end. In this embodiment, the method according to the invention is designed such that
  • From the end support of a cigarette tube before filling the paper tube with tobacco, first the support filter piece is separated, whereupon
  • the tobacco is introduced, wherein the remaining remainder of the paper ring serves as a mold support for the open end, whereupon
  • the remaining part of the paper ring is separated.

In diesem Fall kann der zunächst stehen bleibende Ring die Formerhaltung des Befüllungsvorgangs noch besser garantieren - er kann danach abgeschnitten werden.In this case, the first ring standing still can guarantee the shape retention of the filling process even better - it can then be cut off.

Grundsätzlich könnte man auch Ausführungsformen ins Auge fassen, wo ein relativ wenig auftragender Ring aus einem Zigarettenpapiermaterial verwendet wird, der am Ende stehen bleiben kann und beim Anzünden der Zigaretten mit verbrannt wird.In principle, one could also envisage embodiments where a relatively low-application ring of a cigarette paper material is used, which can remain at the end and is burned when the cigarettes are lit.

Die Erfindung wird im Weiteren anhand von Ausführungsformen und mit Hilfe der beiliegenden Zeichnungen näher erläutert. Sie kann alle hierin beschriebenen Merkmale in jedweder vorteilhaften Kombination oder einzeln umfassen. In den Zeichnungen zeigen:

The invention will be explained in more detail below with reference to embodiments and with the aid of the accompanying drawings. It may include all the features described herein in any advantageous combination or individually. In the drawings show:
FIG. 1
the construction of a cigarette filter sleeve with a filter sleeve end support unit according to the present invention and its preferred use; and
FIG. 2
the manufacturing process of a filter sleeve end support unit in a continuous strand process.

Die Figur 1 zeigt in vier Stufen a bis d, wie aus einer Filterhülsen-Endenstützen-Einheit gemäß der vorliegenden Erfindung eine Zigaretten-Filterhülse gemacht wird. In den beiden Darstellungen a und b ist die Einheit insgesamt zu sehen, wobei die Darstellung der Figur 1a eine Längsschnittansicht und die Darstellung der Figur 1b eine seitliche Ansicht zeigt. Die Filterhülse, die insgesamt mit dem Bezugszeichen 1 bezeichnet ist, weist eine Zigarettenpapierhülse 13 auf, mit einem Filterstück 9 auf der linken Seite und einem Stützfilterstück 11 auf der rechten Seite. Die Papierhülse 13 umgibt das Filterstück 9 sowie das Stützflterstück 11, das ebenfalls aus einem Filtermaterial (z.B. Gewebe, Vlies, etc., insbesondere Celluloseacetat) hergestellt ist, und bildet so einen Hohlraum 3 zwischen den beiden Filterstücken 9, 11. Im Bereich des Filterstücks 9 ist das Filterbelagpapier 5 so um das Filterstück 9 herumgewickelt, dass es auch einen Teil der Papierhülse 13 mit übergreift und damit eine zusätzliche Stützfunktion am Filterende bereitstellt. Diese kann vorteilhaft sein, ist aber nicht unbedingt notwendig; wenn sich, wie im vorliegenden Fall, die Zigarettenpapierhülse 13 über das Filterstück erstreckt, wird schon eine Verbindung zwischen diesen beiden Komponenten bereitgestellt.The FIG. 1 Figure 4 shows, in four stages a to d, how a cigarette filter sleeve is made from a filter sleeve end support unit according to the present invention. In the two representations a and b, the unit as a whole is to be seen, the representation of the FIG. 1a a longitudinal sectional view and the representation of FIG. 1b a side view shows. The filter sleeve, which is designated overall by the reference numeral 1, has a cigarette paper sleeve 13, with a filter piece 9 on the left side and a support filter piece 11 on the right side. The paper sleeve 13 surrounds the filter piece 9 and the support piece 11, which is also made of a filter material (eg fabric, non-woven, etc., especially cellulose acetate), and thus forms a cavity 3 between the two filter pieces 9, 11. In the region of the filter piece 9, the filter cover paper 5 is wound around the filter piece 9 in such a way that it also engages over part of the paper sleeve 13, thus providing an additional support function at the filter end. This can be advantageous, but is not absolutely necessary; if, as in the present case, the cigarette paper sleeve 13 extends over the filter piece, a connection between these two components is already provided.

Auf der rechten Seite, also der Befüllungsseite der Zigaretten-Filterhülse, wo schließlich das offene Ende entstehen soll, ist das Stützfilterstück 11 ebenso mit einem Papier 7 umgeben, das etwas länger ist als das Stützfilterstück 11 und dieses so von außen auf der Papierhülse 13 befestigt.On the right side, so the filling side of the cigarette filter sleeve, where eventually the open end should arise, the support filter piece 11 is also with surrounded a paper 7, which is slightly longer than the support filter piece 11 and this so attached from the outside on the paper tube 13.

Das Stützfilterstück 11 und das Papier 7, das ringförmig ausgebildet ist, bildet hier die Endenstütze, und so wird eine Ausführungsform der prinzipiellen erfindungsgemäßen Idee umgesetzt, die darin liegt, das fragile Material der Papierhülse 13 durch zusätzliche Materialien am äußeren Umfang und/oder innerhalb der Papierhülse zu stützen.The support filter piece 11 and the paper 7, which is annular, here forms the end support, and so an embodiment of the inventive idea is implemented, which is the fragile material of the paper tube 13 by additional materials on the outer periphery and / or within the Support paper sleeve.

Im vorliegenden Fall ist die axiale Länge des Papierrings 7 größer als die diejenige des Stützfilterstücks 11, vorzugsweise 2 bis 6 mm. Die Dicke des Materials des Papierrings 7 hängt von der mechanischen Stabilität des Materials ab.In the present case, the axial length of the paper ring 7 is greater than that of the support filter piece 11, preferably 2 to 6 mm. The thickness of the material of the paper ring 7 depends on the mechanical stability of the material.

Weil beide Enden der Zigaretten-Filterhülse 1 gemäß den Figuren 1 a und 1 b geschlossen sind, muss die gesamte Einheit am rechten Ende geöffnet werden, um für die Zigarettenherstellung Tabak in die Hülse 1 einbringen zu können.Because both ends of the cigarette filter sleeve 1 according to the FIGS. 1 a and 1 b are closed, the entire unit must be opened at the right end to bring tobacco for cigarette production in the sleeve 1 can.

Zum Öffnen des rechten, gestützten Endes der Filterhülse 1 wird das Stützfilterstücks 11 mit Hilfe einer Schneidvorrichtung, vorzugsweise in dem Befüllungsgerät, abgeschnitten. Bis dahin hat das Stützfilterstück 11 sowohl die Produktion der Filterhülse mit Stützfunktion ermöglicht, wie später anhand der Beschreibung der Figur 2 noch ersichtlich wird, als auch das Ende der Filterhülse 1 während des Transportes von der Herstellung bis zum Verwender stabilisiert. Es wird nun nicht mehr gebraucht.To open the right, supported end of the filter sleeve 1, the support filter piece 11 by means of a cutting device, preferably in the filling device, cut off. Until then, the support filter piece 11 has both the production of the filter sleeve with support function allows, as later with reference to the description of FIG. 2 can be seen, as well as the end of the filter sleeve 1 stabilized during transport from manufacture to the user. It is no longer needed.

Der Schnitt wird vorzugsweise direkt an der inneren Oberfläche des Stützfilterstück 11 gesetzt, wobei ein Teil des Papierrings 7, der in Figur 1c mit 7' bezeichnet ist, am Stirnende der Zigarettenhülse 1 verbleibt. Dieser verbleibende Teil hat wiederum eine Stützwirkung und stellt sicher, dass die im Wesentlichen kreisförmige Querschnittsausbildung aufrechterhalten wird. Dadurch steht für die Befülleinrichtung eine stabile, versteifte Endenöffnung zur Verfügung, die den Einfüllvorgang für den Tabak erleichtert und optimiert. Zusätzlich wird die Halterung der Hülse bei der Tabaküberführung erleichtert.The cut is preferably placed directly on the inner surface of the support filter piece 11, wherein a part of the paper ring 7, which in Figure 1c is denoted by 7 ', remains at the front end of the cigarette tube 1. This remaining part in turn has a supporting action and ensures that the substantially circular cross-sectional formation is maintained. As a result, there is a stable, stiffened end opening available for the filling, the filling process for the Tobacco facilitates and optimizes. In addition, the holder of the sleeve is facilitated in the tobacco transfer.

Am Ende wird auch der Restring 7' von der befüllten Zigaretten-Filterhülse 1 an seiner Innenseite abgeschnitten, so dass eine Zigarette mit einem glatten Ende und insgesamt hoher Qualität entsteht, wie sie in Figur 1d dargestellt ist.At the end of the rest ring 7 'is cut off from the filled cigarette filter sleeve 1 on its inside, so that a cigarette with a smooth finish and overall high quality arises, as in Figure 1d is shown.

Die Figur 2 zeigt die wichtigen Schritte des Herstellungsverfahrens für die Filterhülsen. Die Darstellung der Figur 1 und 2 sind schematischer Art und geben den Inhalt nicht maßstabsgetreu wieder. Die Bezugszeichen sind in Figur 2 die gleichen wie in Figur 1, sie sind aber um ein "a" für Endlosmaterialien und durch "b" für Elemente doppelter Länge im Vergleich zur Figur 1 ergänzt worden.The FIG. 2 shows the important steps of the manufacturing process for the filter sleeves. The presentation of the FIG. 1 and 2 are schematic and do not reflect the content to scale. The reference numerals are in FIG. 2 the same as in FIG. 1 However, they are an "a" for continuous materials and a "b" for double-length elements compared to FIG. 1 been supplemented.

Die Figur 2a zeigt einen Längsschnitt einer Endlos-Papierhülse 13a, wobei leere Bereiche 3b zwischen Filterelementen 9b von doppelter Zigarettenfilterlänge und Endenstützelementen 11 b der doppelten Länge einer Endenstütze vorhanden sind. Dieser Aufbau wird mit Hilfe von Standard-Filterhülsen-Produktionstechnologien hergestellt, wobei lediglich eine zweite Bereitstellung und Zuführung für die Stützfilterstück-Elemente mit der doppelten Länge vorgesehen werden muss.The FIG. 2a shows a longitudinal section of an endless paper tube 13a, wherein empty areas 3b between filter elements 9b of double cigarette filter length and end support members 11 b double the length of an end support are present. This construction is made using standard filter sleeve production technologies, with only a second supply and delivery for the double length filter filter element elements being required.

Die Figur 2b zeigt nun, dass ein Filterbelagpapier 5b von doppelter Länge jeweils auf das doppelte Filterelement 9b aufgebracht wird, nachdem der Endlosstrang in der Mitte der Stützfilterstück-Elemente 11 b in Figur 2a geschnitten worden ist. Aus der Figur 2c geht hervor, dass die beiden Doppel-Filterhülsen mit den aufgerollten Belagpapieren 5b dann gemäß der Darstellung in Figur 2d in der Mitte der Filterelemente geschnitten werden, so dass zwei Zigaretten-Filterhülsen 1 mit Filterbelagpapieren 5 im Filterbereich entstehen.The FIG. 2b now shows that a filter lining paper 5b of double length each is applied to the double filter element 9b, after the endless strand in the middle of the support filter element elements 11 b in FIG. 2a has been cut. From the Figure 2c It can be seen that the two double filter sleeves with the rolled up liner papers 5b then as shown in Figure 2d be cut in the middle of the filter elements, so that two cigarette filter sleeves 1 with Filterbelagpapieren 5 arise in the filter area.

Die Figur 2e zeigt schließlich, dass zur Herstellung einer Filterhülsen-Endenstützen-Einheit am Befüllungsende um das Stützfilterstück herum noch der Papierring 7 aufgerollt und verklebt wird, und zwar grundsätzlich in derselben Art und Weise wie beim Aufbringen des Filterbelagpapiers 5b.The FIG. 2e shows finally that for producing a filter sleeve end support unit at the filling end around the support filter piece around the paper ring 7 is rolled up and glued, in principle in the same manner as in the application of the filter pad paper 5b.

Damit ist nun nach dem Schritt der Figur 2e eine Filterhülsen-Endenstützen-Einheit entstanden, wie sie in der Figur 1 in den Zeilen a und b gezeigt wird und die entsprechend der obigen Beschreibung zu einer fertigen Zigarette weiterverarbeitet werden kann.This is now after the step of FIG. 2e a filter sleeve end support unit emerged, as in the FIG. 1 is shown in lines a and b and can be further processed according to the above description to a finished cigarette.
