Definitions
- the invention relates to a method for the production of filter cigarettes according to claim 1 or 2.
- a filter cigarette has become known in which the filter consists of two longitudinally aligned air-permeable components, with a common enclosure.
- the first component is intended to produce a relatively large pressure drop in the longitudinal direction of the filter, but to be substantially impermeable to air in the radial direction of the filter over its entire cross section.
- the second component should produce a relatively low pressure drop in the longitudinal direction of the filter, which should also be permeable to air in the radial direction.
- the components may abut one another or may also be spaced from one another, wherein ventilation of the filter should be ensured at a distance from the first component adjoining the tobacco rod, preferably through the chamber resulting from the distance between the filter components.
- the envelope is perforated, so that a better distribution of tobacco smoke over the entire cross section in the filter area is achieved with a reduction in the condensate and nicotine content, without the cigarette taste is adversely affected.
- the structure of the known cigarette is such that the one filter component has its own envelope and the common envelope at the same time represents the envelope for the second component. The latter is at the same time the envelope for the tobacco rod.
- the connection of the filter section with the tobacco rod takes place with the help of another wrapping, which covers the tobacco rod at the end facing a certain length.
- the production of such a filter cigarette is extremely complicated.
- the invention has for its object to provide a method for producing a filter cigarette with substantially the components of the known filter cigarette, which can be carried out in a simple and effective manner and with the filter assembly can be varied in various ways in a simple manner.
- an endless strand is generated from each filter material.
- the respective filter material is e.g. Acetate or carbon granules.
- first and second sections are separated with their wrapping of predetermined length. The length for both sections is e.g. or preferably the same.
- another endless strand is formed by sequentially strung the sections. The array is done with a predetermined distance from each other, according to an embodiment 3 to 6 cm, the series is continuously wrapped with another enclosure.
- Each double filter section has three sections, namely in the end regions a first section of half length and in the middle a second section of full length or vice versa.
- the other filter section which consists for example of acetate or a paper filter, at the mouthpiece end.
- the double filter sections are then each arranged between two tobacco rods and connected to these and severed centrally. This is usually done on a corresponding drum of a cigarette-making machine.
- a distance between the filter parts can be generated in a simple manner to form a ventilation chamber of the desired length.
- the filter sections are arranged in shock to shock in the creation of the third endless strand, and in the connection with the tobacco rod, a corresponding chamber is generated by distance formation.
- the wrapping around the filter part can be perforated as desired. A geometrically defined perforation hole arrangement is not required.
- the filter cigarette 10 of FIG. 1 is composed of a tobacco rod 12 and a filter part 18.
- the tobacco rod consists of a tobacco rod section 14 which is surrounded by a Textilumhüllung 16.
- the filter part 18 consists of a first filter section 20 and a second filter section 22, which consist of different materials and are arranged at a distance from each other, whereby a distance results, which is indicated by the dashed line 24.
- the two filter sections 20, 22 are connected to the tobacco rod 12 by means of a common cover, which is indicated at 26.
- endless strands are produced from the filter material for the first and second filters as shown in Fig. 1 (not shown).
- the filter material may e.g. on the one hand consist of acetate or paper filter and on the other hand from carbon granules. Both are known.
- the endless strands are each provided with a suitable sheath, e.g. made of paper.
- first and second sections of predetermined are generated. This can be done in stages, for example by first sections of a length of 132 mm are generated, which are then subdivided into lengths of 44 mm, which then in turn once again separated into sections of 22 mm in length and then subsequently, as in Fig. 2 shown, alternated to another endless strand stringed together.
- the sections are designated 30 and 32 in FIG. As shown in Fig. 2, the sections 30, 32 are each lined up in pairs, with a gap of, for example, 3 to 6 mm is left between the sections. This gap is designated 34.
- This continuous strand is provided during its production with a sheath (not shown). The continuous strand is, as also indicated in Fig.
- Each double filter section is composed of a central portion 32 and end portions, which are formed by half the length of each section 30.
- the wrapped double filter sections 36 are placed between two tobacco sticks, particularly on a conventional drum of a cigarette making machine (not shown). After connection with the tobacco rods, the double filter sections 36 are severed in the middle, as indicated by the dot-dash line 38 in FIG. This results in filter sections 40, 42 each 11 mm in length (the sections 30, 32 have, as described, a length of 22 mm). The distance 34 has remained the same.
- the arrangement of the filter sections 40, 42 with the common enclosure 44 is then subsequently connected to a tobacco rod 46 by means of a further enclosure 48, which covers the tobacco rod at the end somewhat, as is known per se.
- a further distance 50 is shown, which is formed between the filter section 42 and the tobacco rod 46. This is either alternatively formed to the distance 34 or together with this. Both distances 34, 50 each form a ventilation chamber for the smoke from the tobacco rod 46, whereby condensate and nicotine content is reduced.
- the casing 48 or the casing 44 can be perforated as desired in a known manner. The attachment of perforation holes in certain places is not required. The perforation of wrappings is also known per se.
- the method described can be carried out with known machines for the production of filter cigarettes. A special equipment expense is not required.

Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Filterzigaretten nach dem Patentanspruch 1 oder 2.The invention relates to a method for the production of filter cigarettes according to claim 1 or 2.
Aus DE 36 35 958 oder US 4 807 647 ist eine Filterzigarette bekannt geworden, bei der das Filter aus zwei in Längsrichtung fluchtenden luftdurchlässigen Komponenten besteht, mit einer gemeinsamen Umhüllung. Die erste Komponente soll einen verhältnismäßig großen Druckabfall in Längsrichtung des Filters erzeugen, in Radialrichtung des Filters jedoch über ihren ganzen Querschnitt im Wesentlichen luftundurchlässig sein. Die zweite Komponente soll in Längsrichtung des Filters einen relativ niedrigen Druckabfall erzeugen, wobei diese in Radialrichtung ebenfalls luftdurchlässig sein soll. Die Komponenten können aneinander stoßen oder auch einen Abstand voneinander aufweisen, wobei im Abstand von der ersten, sich an den Tabakstock anschließenden Komponente eine Ventilation des Filters gewährleistet sein soll, vorzugsweise durch die Kammer, die sich aus dem Abstand zwischen den Filterkomponenten ergibt. In diesem Bereich ist die Umhüllung perforiert, sodass eine bessere Verteilung des Tabakrauchs über den gesamten Querschnitt im Filterbereich erreicht wird mit einer Reduzierung des Kondensat- und Nikotingehalts, ohne dass der Zigarettengeschmack negativ beeinflusst wird. Der Aufbau der bekannten Zigarette ist derart, dass die eine Filterkomponente eine eigene Umhüllung aufweist und die gemeinsame Umhüllung zugleich die Umhüllung für die zweite Komponente darstellt. Letztere ist zugleich die Umhüllung für den Tabakstock. Die Verbindung des Filterabschnitts mit dem Tabakstock erfolgt mit Hilfe einer weiteren Umhüllung, die den Tabakstock am zugekehrten Ende eine gewisse Teillänge überdeckt. Die Herstellung einer derartigen Filterzigarette gestaltet sich außerordentlich aufwändig.From DE 36 35 958 or US 4 807 647 a filter cigarette has become known in which the filter consists of two longitudinally aligned air-permeable components, with a common enclosure. The first component is intended to produce a relatively large pressure drop in the longitudinal direction of the filter, but to be substantially impermeable to air in the radial direction of the filter over its entire cross section. The second component should produce a relatively low pressure drop in the longitudinal direction of the filter, which should also be permeable to air in the radial direction. The components may abut one another or may also be spaced from one another, wherein ventilation of the filter should be ensured at a distance from the first component adjoining the tobacco rod, preferably through the chamber resulting from the distance between the filter components. In this area, the envelope is perforated, so that a better distribution of tobacco smoke over the entire cross section in the filter area is achieved with a reduction in the condensate and nicotine content, without the cigarette taste is adversely affected. The structure of the known cigarette is such that the one filter component has its own envelope and the common envelope at the same time represents the envelope for the second component. The latter is at the same time the envelope for the tobacco rod. The connection of the filter section with the tobacco rod takes place with the help of another wrapping, which covers the tobacco rod at the end facing a certain length. The production of such a filter cigarette is extremely complicated.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung einer Filterzigarette mit im Wesentlichen den Komponenten der bekannten Filterzigarette anzugeben, das sich auf einfache und wirksame Weise durchführen lässt und mit dem der Filteraufbau in verschiedener Hinsicht in einfacher Weise variiert werden kann.The invention has for its object to provide a method for producing a filter cigarette with substantially the components of the known filter cigarette, which can be carried out in a simple and effective manner and with the filter assembly can be varied in various ways in a simple manner.
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 und 2 gelöst.This object is solved by the features of claims 1 and 2.
Bei dem erfindungsgemäßen Verfahren wird aus jedem Filtermaterial jeweils ein Endlosstrang erzeugt. Das jeweilige Filtermaterial ist z.B. Acetat oder Kohlegranulat. Aus diesen Endlossträngen werden erste und zweite Abschnitte mit ihrer Umhüllung vorgegebener Länge abgetrennt. Die Länge für beide Abschnitte ist z.B. bzw. vorzugsweise gleich. Aus dem ersten und zweiten Abschnitt wird ein weiterer Endlosstrang gebildet, indem die Abschnitte nacheinander aufgereiht werden. Die Aufreihung geschieht mit einem vorgegebenen Abstand voneinander, nach einem Ausführungsbeispiel 3 bis 6 cm, wobei die Reihe fortlaufend mit einer weiteren Umhüllung umhüllt wird. Aus diesem weiteren Endlosstrang werden Doppelfilterabschnitte erzeugt. Jeder Doppelfilterabschnitt weist drei Teilabschnitte auf, nämlich in den Endbereichen einen ersten Abschnitt von halber Länge und in der Mitte einen zweiten Abschnitt von ganzer Länge oder auch umgekehrt.In the method according to the invention, an endless strand is generated from each filter material. The respective filter material is e.g. Acetate or carbon granules. From these endless strands first and second sections are separated with their wrapping of predetermined length. The length for both sections is e.g. or preferably the same. From the first and second sections, another endless strand is formed by sequentially strung the sections. The array is done with a predetermined distance from each other, according to an embodiment 3 to 6 cm, the series is continuously wrapped with another enclosure. For this further endless strand double filter sections are generated. Each double filter section has three sections, namely in the end regions a first section of half length and in the middle a second section of full length or vice versa.
Bei Doppelfilteranordnungen, insbesondere solchen, die Kohlegranulat enthalten, ist es üblich, den anderen Filterabschnitt, der z.B. aus Acetat oder einem Papierfilter besteht, am Mundstückende vorzusehen. Dies geschieht in erster Linie aus ästhetisehen Gründen. Daher ist die Anordnung der Teilabschnitte im Doppelfilterabschnitt derart, dass die Endabschnitte halber Länge aus demjenigen Filtermaterial bestehen, das das Ende des Mundstücks bilden soll. Die Doppelfilterabschnitte werden dann jeweils zwischen zwei Tabakstöcken angeordnet und mit diesen verbunden und mittig durchtrennt. Üblicherweise geschieht dies auf einer entsprechenden Trommel einer Zigaretten-Herstellmaschine.In double-filter arrangements, in particular those containing carbon granules, it is customary to provide the other filter section, which consists for example of acetate or a paper filter, at the mouthpiece end. This is primarily aesthetic Establish. Therefore, the arrangement of the sections in the double filter section is such that the half-length end sections consist of the filter material intended to form the end of the mouthpiece. The double filter sections are then each arranged between two tobacco rods and connected to these and severed centrally. This is usually done on a corresponding drum of a cigarette-making machine.
Mit Hilfe des erfindungsgemäßen Verfahrens kann auf einfache Weise ein Abstand zwischen den Filterteilen erzeugt werden zur Bildung einer Ventilationskammer von gewünschter Länge.With the aid of the method according to the invention, a distance between the filter parts can be generated in a simple manner to form a ventilation chamber of the desired length.
Bei der Lösung nach Patentanspruch 2 werden bei der Erstellung des dritten Endlosstrangs die Filterabschnitte Stoß an Stoß angeordnet, und bei der Verbindung mit den Tabakstock wird durch Abstandsbildung eine entsprechende Kammer erzeugt. Die Umhüllung um das Filterteil kann beliebig perforiert sein. Eine geometrisch festgelegte Perforationsbohrungsanordnung ist nicht erforderlich.In the solution according to claim 2, the filter sections are arranged in shock to shock in the creation of the third endless strand, and in the connection with the tobacco rod, a corresponding chamber is generated by distance formation. The wrapping around the filter part can be perforated as desired. A geometrically defined perforation hole arrangement is not required.

Die Filterzigarette 10 nach Fig. 1 setzt sich zusammen aus einem Tabakstock 12 und einem Filterteil 18. Der Tabakstock besteht aus einem Tabakstrangabschnitt 14, der von einer Papierumhüllung 16 umgeben ist. Der Filterteil 18 besteht aus einem ersten Filterabschnitt 20 und einem zweiten Filterabschnitt 22, die aus verschiedenen Materialien bestehen und im Abstand zueinander angeordnet sind, wodurch sich ein Abstand ergibt, der durch die gestrichelte Linie 24 angedeutet ist. Die beiden Filterabschnitte 20, 22 werden mittels einer gemeinsamen Umhüllung, die bei 26 angedeutet ist, mit dem Tabakstock 12 verbunden.The
Bei dem Verfahren zur Herstellung der erfindungsgemäßen Filterzigarette werden Endlosstränge aus dem Filtermaterial für das erste und zweite Filter, wie sie in Fig. 1 gezeigt sind, erzeugt (nicht dargestellt). Das Filtermaterial kann z.B. zum einen aus Acetat oder Papierfilter bestehen und zum anderen aus Kohlegranulat. Beides ist an sich bekannt. Die Endlosstränge sind jeweils mit einer geeigneten Umhüllung, z.B. aus Papier, versehen.In the method for producing the filter cigarette of the present invention, endless strands are produced from the filter material for the first and second filters as shown in Fig. 1 (not shown). The filter material may e.g. on the one hand consist of acetate or paper filter and on the other hand from carbon granules. Both are known. The endless strands are each provided with a suitable sheath, e.g. made of paper.
Aus den Endlossträngen werden erste und zweite Abschnitte vorgegebener, vorzugsweise gleicher Länge erzeugt. Dies kann in Stufen geschehen, indem z.B. zunächst Abschnitte einer Länge von 132 mm erzeugt werden, die anschließend in Längen von 44 mm unterteilt werden, die dann ihrerseits noch einmal zu Abschnitten von 22 mm Länge getrennt und welche dann anschließend, wie in Fig. 2 gezeigt, abwechselnd zu einem weiteren Endlosstrang aneinander gereiht werden. Die Abschnitte sind in Fig. 2 mit 30 bzw. 32 bezeichnet. Wie in Fig. 2 dargestellt, werden die Abschnitte 30, 32 jeweils paarweise aneinander gereiht, wobei zwischen den Abschnitten jeweils eine Lücke von z.B. 3 bis 6 mm gelassen wird. Diese Lücke ist mit 34 bezeichnet. Dieser Endlosstrang wird während seiner Herstellung mit einer Umhüllung versehen (nicht dargestellt). Der Endlosstrang wird, wie ebenfalls in Fig. 2 angedeutet, in Doppelfilterabschnitte 36 unterteilt. Jeder Doppelfilterabschnitt setzt sich zusammen aus einem mittleren Abschnitt 32 und Endabschnitten, welche von der halben Länge jeweils eines Abschnitts 30 gebildet sind. Die umhüllten Doppelfilterabschnitte 36 werden zwischen zwei Tabakstöcken angeordnet, insbesondere auf einer üblichen Trommel einer Zigarettenherstellungsmaschine (nicht gezeigt). Nach der Verbindung mit den Tabakstöcken werden die Doppelfilterabschnitte 36 in der Mitte durchtrennt, wie durch die strichpunktierte Linie 38 in Fig. 2 angedeutet. Dadurch ergeben sich Filterabschnitte 40, 42 von jeweils 11 mm Länge (die Abschnitte 30, 32 haben, wie beschrieben, eine Länge von 22 mm). Der Abstand 34 ist der gleiche geblieben. Die Anordnung aus den Filterabschnitten 40, 42 mit der gemeinsamen Umhüllung 44 wird dann anschließend mit einem Tabakstock 46 mit Hilfe einer weiteren Umhüllung 48, welche den Tabakstock am Ende etwas überdeckt, verbunden, wie dies an sich bekannt ist.From the endless strands first and second sections of predetermined, preferably the same length are generated. This can be done in stages, for example by first sections of a length of 132 mm are generated, which are then subdivided into lengths of 44 mm, which then in turn once again separated into sections of 22 mm in length and then subsequently, as in Fig. 2 shown, alternated to another endless strand stringed together. The sections are designated 30 and 32 in FIG. As shown in Fig. 2, the
In Fig. 3 ist ein weiterer Abstand 50 dargestellt, der zwischen dem Filterabschnitt 42 und dem Tabakstock 46 gebildet ist. Dieser wird entweder alternativ zum Abstand 34 gebildet oder auch zusammen mit diesem. Beide Abstände 34, 50 bilden jeweils eine Ventilationskammer für den Rauch aus dem Tabakstock 46, wodurch Kondensat- und Nikotingehalt reduziert wird. Die Umhüllung 48 bzw. die Umhüllung 44 kann in bekannter Weise beliebig perforiert sein. Die Anbringung von Perforationsbohrungen an bestimmten Stellen ist nicht erforderlich. Das Perforieren von Umhüllungen ist ebenfalls an sich bekannt.In Fig. 3, a
Das beschriebene Verfahren lässt sich mit bekannten Maschinen zur Herstellung von Filterzigaretten durchführen. Ein besonderer apparativer Aufwand ist nicht erforderlich. The method described can be carried out with known machines for the production of filter cigarettes. A special equipment expense is not required.
