Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Filtern mit einem Geschmacksstoff für Produkte der Tabak verarbeitenden Industrie mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to an apparatus for producing filters with a flavor for products of the tobacco processing industry having the features of the preamble of claim 1.

Die Filter werden in einem kontinuierlichen Strang aus einem sogenannten Filtertow hergestellt, in welchen ein mit dem Geschmacksstoff getränkter oder benetzter Geschmacksträger eingeführt wird. Es ist auch denkbar, die Filter in mehreren parallelen Strängen herzustellen, bevorzugt mit einer Herstellung der Filter in zwei parallelen Strängen in einer Doppelstrangmaschine. Das Filtertow selbst ist beispielsweise aus einem Celluloseacetat hergestellt, welches mit einem Mittel zum Auflösen der Acetatfasern, insbesondere Triacetin, behandelt wird. Der Geschmacksträger selbst kann z.B. durch einen endlosen Träger, wie z.B. einen Baumwollfaden, ein Acetatfaden, einem saugfähigen Band oder dergleichen, gebildet sein, welcher mit einem Geschmacksstoff getränkt und/oder benetzt und kontinuierlich in den Strang des Filtermaterials eingeführt wird. Der Geschmacksstoff kann z.B. Menthol sein, welcher der rauchenden Person einen frischen Geschmack vermitteln soll. Das Menthol wird in flüssiger Form als Heißmenthol auf den Geschmacksträger aufgebracht und weist zum Zeitpunkt des Aufbringens eine Temperatur zwischen 40 und 45 Grad Celsius auf. Für den Fall, dass die Temperatur des Menthols sinkt, besteht die Gefahr, dass die Viskosität des Menthols steigt und das Menthol seine für die Verteilung wichtige Fließfähigkeit verliert. Wenn die Temperatur des Menthols hingegen eine Obergrenze, beispielsweise eine Temperatur von 80 Grad übersteigt, besteht die Gefahr, dass sich die Geschmackseigenschaften des Menthols verändern. Bis zu einer Temperatur von 70 Grad kann ein Erhalten der Geschmackseigenschaften sicher gewährleistet werden.The filters are produced in a continuous strand from a so-called filter tow into which a flavor carrier soaked in or wetted with the flavor is introduced. It is also conceivable to produce the filters in several parallel strands, preferably with a production of the filters in two parallel strands in a double-strand machine. The filter tow itself is made, for example, from a cellulose acetate which is treated with a means for dissolving the acetate fibers, in particular triacetin. The flavor carrier itself may be formed, for example, by an endless carrier such as a cotton thread, an acetate thread, an absorbent tape or the like, which is soaked with a flavor and / or wetted and continuously introduced into the strand of filter material. The flavoring agent may be, for example, menthol, which should give the smoking person a fresh taste. The menthol is applied in liquid form as a hot menthol on the flavor carrier and has a temperature between 40 and 45 degrees Celsius at the time of application. In the event that the temperature of the menthol decreases, there is a risk that the viscosity of the menthol increases and the menthol increases its flowability important for the distribution loses. On the other hand, if the temperature of menthol exceeds an upper limit, for example, 80 degrees, there is a risk that the taste properties of menthol will change. Up to a temperature of 70 degrees, a preservation of the taste characteristics can be assured.

Ferner ist es das Bestreben der Hersteller, möglichst viel des Geschmacksstoffs in einer möglichst gleichmäßigen Verteilung in den Filterstrang einzubringen. Aus diesem Grund ist eine hohe Beladung des Geschmacksträgers mit Geschmacksstoff anzustreben, da der Geschmacksstoff dadurch von dem Geschmacksträger in einer größeren Menge in das Filtermaterial eingebracht werden kann. Werden die Geschmacksstoffe mit einer hohen Beladung auf die Geschmacksträger aufgetragen, besteht die Schwierigkeit in einem ausreichend schnellen, sowohl in Längsrichtung als auch quer zur Längsrichtung, homogenen Auftrag auf die sich mit hoher Geschwindigkeit bewegenden Geschmacksträger. Eine eventuell dadurch bedingte Inhomogenität des Auftrags kann zu Unterschieden im Geschmack und Zugwiderstand der Filter der aufeinanderfolgenden Züge an der Zigarette führen. Insgesamt bildet der Auftrag des Geschmacksstoffes und das Einbringen des Geschmacksträgers mit dem aufgetragenen Geschmacksstoff in den Strang des Filtermaterials eine komplexe Aufgabenstellung, bei deren Lösung eine Vielzahl von Aspekten zu berücksichtigen sind. Aus diesem Grund ist die Menge des aufbringbaren Geschmacksstoffs bei den im Stand der Technik bekannten Lösungen begrenzt.Furthermore, it is the desire of the manufacturer to bring as much of the flavor in a uniform distribution as possible in the filter strand. For this reason, a high loading of the flavor carrier with flavor is desirable, since the flavor can be introduced by the flavor carrier in a larger amount in the filter material. When the flavorings are applied to the flavor carriers with a high load, the difficulty is to apply homogeneously to the high-speed flavor carriers in a sufficiently fast, both longitudinal and transverse, longitudinal direction. Any resulting inhomogeneity of the job may result in differences in the taste and draw resistance of the filters of the successive courses on the cigarette. Overall, the application of the flavor and the introduction of the flavor carrier with the flavor applied in the strand of the filter material is a complex task in the solution of a variety of aspects are taken into account. For this reason, the amount of coatable flavor is limited in the solutions known in the art.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der möglichst viel Geschmacksstoff auf den Geschmacksträger und in das Filtermaterial aufgebracht bzw. eingebracht werden kann, ohne dass dabei die Gefahr einer Verschmutzung der Vorrichtung und/oder einer ungleichmäßigen Verteilung des Geschmacksstoffes besteht.Against this background, the invention has the object to provide a device with which as much flavor on the flavor carrier and in the filter material can be applied or introduced, without thereby there is a risk of fouling of the device and / or uneven distribution of the flavor.

Gemäß dem Grundgedanken der Erfindung wird zur Lösung der Aufgabe vorgeschlagen, dass die zweite Zuführeinrichtung in Bezug zu der Bewegungsrichtung des Stranges stromabwärts zu der ersten Zuführeinrichtung angeordnet ist. Dadurch wird der Geschmacksstoff an einer Stelle auf den Geschmacksträger aufgegeben, an der er bereits teilweise von dem Filtermaterial umfasst ist, so dass der Geschmacksstoff, selbst wenn er nicht von dem Geschmacksträger aufgenommen wird, in jedem Fall von dem Filtermaterial aufgenommen und abtransportiert wird, statt die Vorrichtung zu verschmutzen. Ferner kann dadurch verhindert werden, dass der Geschmacksstoff trotz eines übersättigten Auftrages zu Tropfen zusammenfließt, da er vorher von dem Filtermaterial aufgesaugt wird. Der Geschmacksträger selbst zeichnet sich durch eine besondere Saugfähigkeit aus und bildet praktisch einen Zwischenspeicher während der Transportbewegung des Stranges, von dem sich der Geschmacksstoff nach dem vollständigen Umfassen durch das Filtermaterial gleichmäßig ausbreitet.According to the basic idea of the invention, it is proposed to achieve the object that the second feed device is arranged with respect to the direction of movement of the strand downstream of the first feed device. Thereby, the flavor is placed on the flavor carrier at a location where it is already partially covered by the filter material, so that the flavor, even if not taken up by the flavor carrier, is in any case taken up and removed by the filter material to pollute the device. Furthermore, it can be prevented that the flavoring material, despite a supersaturated order, flows together into droplets since it is previously absorbed by the filter material. The flavor carrier itself is characterized by a special absorbency and practically forms a buffer during the transport movement of the strand, from which the flavor spreads evenly after complete encirclement by the filter material.

Weiter wird vorgeschlagen, dass die zweite Zuführeinrichtung derart ausgerichtet ist, dass der Geschmacksstoff in einem Winkel zwischen 60 Grad und 80 Grad in Bewegungsrichtung des Geschmacksträgers aufgebracht wird. Der Geschmacksstoff wird dadurch praktisch gleich mit einer in Bewegungsrichtung des Geschmacksträger bzw. des Stranges gerichteten Bewegungskomponente auf den Geschmacksträger aufgebracht, wodurch der gerichtete Abtransport des Geschmackstoffes begünstigt wird.It is further proposed that the second feed device is oriented such that the flavor is applied at an angle between 60 degrees and 80 degrees in the direction of movement of the flavor carrier. The flavor is thereby applied to the taste carrier practically the same with a directed in the direction of movement of the flavor carrier or the strand movement component, whereby the directed removal of the flavor is favored.

Das Aufbringen des Geschmacksstoffes kann weiter verbessert werden, indem die erste Zuführeinrichtung in den Strang des Filtermaterials hineinragt und dadurch stromabwärts einen Freiraum in dem Strang schafft, in dem der in den Strang eingebrachte Geschmacksträger frei zugänglich ist, und die zweite Zuführeinrichtung derart angeordnet ist, dass sie mit einer Austrittsöffnung auf den in dem Freiraum frei zugänglichen Geschmacksträger gerichtet ist. Die erste Zuführeinrichtung bildet praktisch ein Hindernis, hinter dem stromabwärts ein Freiraum gebildet wird, welcher frei von Filtermaterial ist, so dass der aus der ersten Zuführeinrichtung austretende Geschmacksträger frei zugänglich ist. Die zweite Zuführeinrichtung ist dann auf den frei zugänglichen Abschnitt des Geschmacksträgers gerichtet, so dass der Geschmacksstoff bevorzugt auf den Geschmacksträger aufgetragen und von diesem aufgesogen wird. Ferner kann die zweite Zuführeinrichtung so angeordnet werden, dass sie den Geschmacksstoff auf den Geschmacksträger aufbringt, ohne den Strang in der Bewegung zu behindern bzw. ohne selbst durch den Strang des Filtermaterials mechanisch belastet zu werden.The application of the flavor can be further improved by placing the first feeder in the strand of the Protruding filter material and thereby downstream creates a free space in the strand in which the flavor carrier introduced into the strand is freely accessible, and the second feeding device is arranged such that it is directed with an outlet opening on the freely accessible in the free space flavor carrier. The first feeder practically forms an obstacle, downstream of which a free space is formed, which is free of filter material, so that the flavor carrier emerging from the first feeder is freely accessible. The second feed device is then directed onto the freely accessible section of the flavor carrier, so that the flavor is preferably applied to and absorbed by the flavor carrier. Further, the second feeder may be arranged to apply the flavor to the flavor carrier without interfering with the strand in motion or without being mechanically stressed by the strand of the filter material itself.

Dabei wird weiter vorgeschlagen, dass die erste Zuführeinrichtung mit einem Endabschnitt in den Strang mündet, und die zweite Zuführeinrichtung in einem Abstand zu der ersten Zuführeinrichtung angeordnet ist, welcher kleiner als die maximale Außenabmessung des Endabschnittes senkrecht zu der Bewegungsrichtung des Stranges ist. Die geometrischen Abmessungen des Freiraumes sind entscheidend von den Abmessungen des in den Strang hineinragenden Endabschnitts der ersten Zuführeinrichtung abhängig. Dabei gilt der Zusammenhang, je größer die maximale Außenabmessung des Endabschnitts ist, desto breiter und länger ist der gebildete Freiraum. Durch die vorgeschlagene Bemessung des Abstandes der zweiten Zuführeinrichtung zu der ersten Zuführeinrichtung kann die mechanische Belastung der zweiten Zuführeinrichtung sehr gering gehalten werden, da die Fasern des Filtermaterials hier noch nicht so dicht komprimiert sind. Dabei gilt grundsätzlich, je dichter die zweite Zuführeinrichtung an der ersten Zuführeinrichtung angeordnet ist, desto geringer ist die Belastung der zweiten Zuführeinrichtung. Ferner wird der Geschmacksstoff dadurch zu einem Zeitpunkt auf den Geschmacksträger aufgebracht, zu dem das Filtermaterial den Geschmacksträger noch lose umfasst, so dass die Zeit zur Verteilung des Geschmacksstoffes in dem Filtermaterial während der anschließenden Verdichtung des Stranges noch möglichst lang ist, wodurch wiederum eine gleichmäßigere Verteilung des Geschmacksstoffes über den Querschnitt des Filters erzielt werden kann.It is further proposed that the first feeder opens into the strand with one end section, and the second feeder is arranged at a distance from the first feeder, which is smaller than the maximum outer dimension of the end section perpendicular to the direction of movement of the strand. The geometric dimensions of the free space are decisively dependent on the dimensions of the end section of the first feed device projecting into the strand. In this context, the greater the maximum outer dimension of the end section, the wider and longer the free space formed. Due to the proposed dimensioning of the distance of the second feed device to the first feed device, the mechanical load on the second feed device can be kept very low, since the fibers of the filter material are not yet compressed so tight here. In principle, the closer the second feed device is arranged to the first feed device, the lower the load on the second feed device. Furthermore, the flavor is thereby applied to the flavor carrier at a time when the filter material still loosely comprises the flavor carrier, so that the time to disperse the flavor in the filter material during the subsequent compression of the strand is as long as possible, which in turn results in a more even distribution of the flavor can be achieved across the cross section of the filter.

Dabei kann besonders viel Geschmacksstoff in den Filter eingebracht werden, wenn die von der zweiten Zuführeinrichtung zugeführte Menge des Geschmacksstoffes derart bemessen ist, dass der Geschmacksstoff in einer den Geschmacksträger übersättigenden Menge aufgetragen wird. Der Geschmacksträger dient in diesem Fall nicht nur zum Aufsaugen des Geschmacksstoffes, sondern außerdem auch zum Abtransportieren des außen anhaftenden Geschmacksstoffes, welcher erst beim nachfolgenden Komprimieren des Stranges in das Filtermaterial eindringt.In this case, a particularly large amount of flavoring agent can be introduced into the filter if the quantity of flavoring agent supplied by the second feeding device is dimensioned in such a way that the flavoring agent is applied in an amount which over-saturates the flavoring agent. The flavor carrier is used in this case not only for absorbing the flavor, but also for transporting away the externally adhering flavor, which penetrates only during subsequent compression of the strand in the filter material.

Ferner wird vorgeschlagen, dass die erste Zuführeinrichtung durch ein gekrümmtes Rohr gebildet ist, welches mit einem im Wesentlichen parallel zu der Längsachse des Stranges gerichteten Endabschnitt in den Strang hineinragt. Der Geschmacksträger wird dadurch gleich in Bewegungsrichtung des Stranges eingelegt und anschließend nicht mehr umgelenkt, wodurch eine Abweichung der Lage des Geschmacksträgers von der bevorzugten zentrischen Ausrichtung vermieden werden kann.It is also proposed that the first feed device is formed by a curved tube which projects into the strand with an end section directed essentially parallel to the longitudinal axis of the strand. The flavor carrier is thereby inserted immediately in the direction of movement of the strand and then no longer deflected, whereby a deviation of the position of the flavor carrier from the preferred centric alignment can be avoided.

Ferner kann die zweite Zuführeinrichtung beheizt sein, so dass der Geschmacksstoff mit einer vorbestimmten Temperatur aufgetragen wird. Da die Temperatur entscheidend für die Viskosität und die Fließfähigkeit des Geschmacksträgers ist, kann dadurch ein Flocken des Geschmacksträgers verhindert und gleichzeitig sichergestellt werden, dass der Geschmacksstoff beim Auftragen eine für die Verteilung optimale Temperatur aufweist.Further, the second feeder may be heated so that the flavor is applied at a predetermined temperature. Since the temperature is critical to the viscosity and flowability of the flavor carrier, it can prevent flake of the flavor carrier while ensuring that the flavor has an optimum distribution temperature during application.

Weiter wird vorgeschlagen, dass die zweite Zuführeinrichtung und die erste Zuführeinrichtung an den in den Strang hineinragenden Abschnitten miteinander verbunden sind. Durch die Verbindung kann ein mechanisch stabiler Verbund geschaffen werden. Außerdem kann die zweite Zuführeinrichtung dadurch bei einer entsprechend stabilen Befestigung mit einem konstanten, auch durch die Strangbewegung nicht veränderlichen Abstand zu der ersten Zuführeinrichtung angeordnet werden.It is further proposed that the second feed device and the first feed device are connected to each other at the sections projecting into the strand. Through the connection, a mechanically stable bond can be created. In addition, the second feeding device can thereby be arranged at a correspondingly stable attachment with a constant, not changeable by the strand movement distance to the first feeder.

Weiterhin wird vorgeschlagen, dass der Strang in einer Formatgarnitur geführt ist, in welcher der Strang mittels einem oder mehreren Formatoberteilen zu einem runden Querschnitt komprimiert und durch einen Umhüllungsstreifen formfixiert wird, und dass eines der Formatoberteile einen Freiraum aufweist, durch welchen die zweite Zuführeinrichtung radial von außen hineinragt. Der Geschmacksträger kann dadurch zeitgleich zu der Formgebung des Stranges mit Geschmacksstoff benetzt werden, wodurch die Baulänge der gesamten Vorrichtung verkürzt werden kann. Ferner wird der Strang dadurch unmittelbar nach dem Benetzen des Geschmacksträgers zu dem vollständig komprimierten und durch den Umhüllungsstreifen formfixierten Strang weiter geformt, so dass die Zeitspanne, während der der Geschmacksstoff noch entweichen kann, möglichst kurz ist.Furthermore, it is proposed that the strand is guided in a Formiturn, in which the strand is compressed by means of one or more format upper parts to a round cross-section and is fixed in shape by a wrapping strip, and that one of the format tops has a free space through which the second feed radially from protrudes outside. The flavor carrier can thereby be wetted with flavor at the same time as the shaping of the strand, whereby the overall length of the entire device can be shortened. Further, the strand is thereby further formed immediately after the wetting of the flavor carrier to the fully compressed and form-fixed by the wrapping strip strand so that the period of time during which the flavor can still escape, is as short as possible.

Die vorgeschlagene Lösung hat sich besonders bewährt, wenn der Geschmacksstoff ein aufschmelzbares Additiv, insbesondere Heißmenthol, ist und mit einer die Fließfähigkeit bewirkenden Temperatur von 40 bis 70 Grad Celsius, bevorzugt bis 60 Grad Celsius und besonders bevorzugt bis 50 Grad Celsius aufgebracht wird.The proposed solution has proven particularly useful when the flavor is a meltable additive, in particular Heißmenthol, and is applied with a flowability causing temperature of 40 to 70 degrees Celsius, preferably up to 60 degrees Celsius and more preferably to 50 degrees Celsius.

Dabei weist die Formatgarnitur zwei Formatoberteile 7a und 7b auf, welche den Umhüllungsstreifen durch ihre Formgebung seitlich hochschlagen und anschließend an der Oberseite umschlagen und das Filtermaterial dabei gleichzeitig auf einen kleineren Durchmesser verdichten.In the Fig. 1 is the device with the endless, supplied from the right side strand 5 of the filter material to recognize, which is transported by a guided in a format garnish 7 and driven by a drive device, not shown format tape in the direction of movement B. The strand 5 is placed on an already laid on the format tape wrapping strip, which is turned up in the format garnish 7 on the sides of the strand 5 and bonded to the edge sides for fixing the shape of the strand 5. The strand 5 is first introduced with a loose arrangement of the fibers of the filter material in a funnel device 6 and then compressed during the further movement path in the format set 7 to a smaller diameter. In this case, the format garnish two format tops 7a and 7b, which the wrapping strip by their Flip up shaping at the side and then turn over at the top and at the same time compact the filter material to a smaller diameter.

Ferner ist eine erste Zuführeinrichtung 4 vorgesehen, welche durch ein gekrümmtes Rohr gebildet ist. Die erste Zuführeinrichtung 4 weist einen senkrechten, aus der Vorrichtung vorstehenden Einführabschnitt 2, einen gekrümmten Umlenkabschnitt 3 und einen parallel zu der Längsachse des vorbeibewegten Stranges 5 gerichteten Endabschnitt 10 auf. In der ersten Zuführeinrichtung 4 ist ein Geschmacksträger 1 geführt, welcher durch eine Austrittsöffnung des Endabschnittes 10 austritt und von dem Strang 5 umfasst und mitgezogen wird. Außerdem ist eine zweite Zuführeinrichtung 8 vorgesehen, welche durch ein beheiztes Rohr gebildet ist, das in einem Winkel C von ca. 75 Grad zu der Längsachse des Stranges 5 gerichtet ist. Die zweite Zuführeinrichtung 8 ist in Richtung der Bewegungsrichtung B des Stranges 5 gerichtet, d.h. leicht zu der ersten Zuführeinrichtung 4 hin geneigt.Furthermore, a first feed device 4 is provided, which is formed by a curved tube. The first feeding device 4 has a vertical, protruding from the device insertion section 2, a curved deflecting section 3 and a parallel to the longitudinal axis of the passing strand 5 directed end portion 10. In the first feeder 4, a flavor carrier 1 is guided, which exits through an outlet opening of the end portion 10 and is encompassed by the strand 5 and pulled along. In addition, a second feed device 8 is provided, which is formed by a heated tube which is directed at an angle C of approximately 75 degrees to the longitudinal axis of the strand 5. The second feeder 8 is directed in the direction of movement B of the strand 5, i. slightly inclined to the first feeder 4.

Mittels der zweiten Zuführeinrichtung 8 wird ein Geschmacksstoff 9, wie z.B. Heißmenthol, mit einer Temperatur von 40 bis 50 Grad Celsius auf den aus der ersten Zuführeinrichtung 4 zugeführten Geschmacksträger 1 aufgegeben, welcher den Geschmacksstoff 9 aufsaugt und abtransportiert. Der Geschmacksstoff 9 wird dabei in einer in Bezug zu der Saugfähigkeit des Geschmacksträgers 1 übersättigten Menge von ca. 580 mg/m bei einem Betrieb mit einer Geschwindigkeit des Stranges 5 und des Geschmacksträgers 1 von 500 bis 600 m/min aufgetragen.By means of the second feeder 8, a flavoring agent 9, e.g. Heißmenthol, abandoned at a temperature of 40 to 50 degrees Celsius on the supplied from the first feeder 4 flavor carrier 1, which absorbs the flavor 9 and transported away. The flavor 9 is applied in a supersaturated with respect to the absorbency of the flavor carrier 1 amount of about 580 mg / m in an operation at a speed of the strand 5 and the flavor carrier 1 from 500 to 600 m / min.

Durch die erste Zuführeinrichtung 4 wird stromabwärts zu dem Endabschnitt 10 aufgrund der Verdrängung des Filtermaterials ein Freiraum 12 geschaffen, welcher in der Fig. 2 zu erkennen ist. Der aus der ersten Zuführeinrichtung 4 austretende Geschmacksträger 1 ist aufgrund der von oben in den Strang 5 hineinragenden ersten Zuführeinrichtung 4 in dem Freiraum 12 an der Oberseite freigelegt bzw. frei zugänglich, also ausschließlich seitlich und an der Unterseite von Filtermaterial umgeben. Die zweite Zuführeinrichtung 8 ragt von oben in diesen Freiraum 12 hinein und ist mit einer Austrittsöffnung 11 auf den freigelegten Geschmacksträger 1 gerichtet, so dass der Geschmacksstoff 9 beim Aufbringen bevorzugt auf den freigelegten Geschmacksträger 1 aufgetragen wird. Da der Geschmacksträger 1 an der Unterseite und in den Seitenabschnitten von Filtermaterial umgeben ist, wird der Anteil des Geschmacksstoffes 9, welcher nicht von dem Geschmacksträger 1 aufgenommen wird, unmittelbar von dem Filtermaterial selbst aufgenommen, so dass der Geschmacksstoff nicht entweicht oder die Vorrichtung verschmutzt.Due to the displacement of the filter material, a free space 12 is created downstream of the end feeder 4 by the first feeder 4, which in the Fig. 2 to recognize is. The emerging from the first feeder 4 flavor carrier 1 is exposed due to the projecting from above into the strand 5 first feeder 4 in the free space 12 at the top or freely accessible, ie only laterally and surrounded at the bottom of filter material. The second feeding device 8 protrudes from above into this free space 12 and is directed with an outlet opening 11 to the exposed flavor carrier 1, so that the flavoring agent 9 is preferably applied to the exposed flavor carrier 1 during application. Since the flavor carrier 1 is surrounded at the bottom and in the side portions of filter material, the portion of the flavor 9 which is not taken up by the flavor carrier 1 is absorbed directly by the filter material itself, so that the flavor does not escape or contaminate the device.

Die zweite Zuführeinrichtung 8 ist mit der Austrittsöffnung 11 unmittelbar angrenzend zu der Austrittsöffnung des Endabschnittes 10 angeordnet und kann sogar mit diesem verbunden sein. Dadurch ist die zweite Zuführeinrichtung 8 und der austretende Geschmacksstoff 9 praktisch im Bewegungsschatten der ersten Zuführeinrichtung 4 angeordnet und wird entsprechend weniger belastet. Da die Geometrie und die Abmaße des gebildeten Freiraumes 12 unmittelbar von der Außengeometrie des Endabschnittes 10 der ersten Zuführeinrichtung 4 abhängen, sollte die zweite Zuführeinrichtung 8 mit der Austrittsöffnung 11 in einem Abstand A von weniger als die maximale Außenabmessung D des Endabschnittes 10 senkrecht zu der Bewegungsrichtung B des Stranges 5 angeordnet sein. Der Abstand A bezieht sich dabei auf den Rand der Austrittsöffnung 11, wie auch in der Fig. 2 zu erkennen ist.The second feeding device 8 is arranged with the outlet opening 11 immediately adjacent to the outlet opening of the end portion 10 and may even be connected thereto. As a result, the second feed device 8 and the exiting flavoring agent 9 are arranged practically in the movement shadow of the first feed device 4 and are loaded correspondingly less. Since the geometry and the dimensions of the formed clearance 12 depend directly on the outer geometry of the end portion 10 of the first feeder 4, the second feeder 8 should communicate with the exit opening 11 at a distance A less than the maximum outer dimension D of the end portion 10 perpendicular to the direction of movement B of the strand 5 may be arranged. The distance A refers to the edge of the outlet opening 11, as well as in the Fig. 2 can be seen.

Ferner ist beim Aufbringen des Geschmacksstoffes 9 der Winkel C der zweiten Zuführeinrichtung 8 von besonderer Bedeutung, da der Geschmacksstoff 9 dadurch praktisch bereits mit einer in Bewegungsrichtung B des Stranges 5 bzw. des Geschmacksträgers 1 gerichteten Bewegungskomponente aufgebracht wird, so dass sich der Geschmacksstoff 9 bevorzugt ausschließlich in eine Richtung ausbreitet bzw. in eine Richtung abtransportiert wird, und nicht entgegen der Bewegungsrichtung B in den Endabschnitt 10 der ersten Zuführeinrichtung 4 eintritt.Furthermore, when applying the flavoring agent 9, the angle C of the second feeding device 8 is of particular importance, since the flavoring agent 9 is practically already applied with a movement component directed in the direction of movement B of the strand 5 or the flavoring carrier 1, so that the flavoring agent 9 is preferred propagates only in one direction or is transported away in one direction, and does not enter against the direction of movement B in the end portion 10 of the first feeder 4.

Da der Geschmacksträger 1 durch den Strang 5 mitgerissen wird und nicht selbst angetrieben ist und der Endabschnitt 10 der ersten Zuführeinrichtung 4 parallel zu dem Strang 5 gerichtet ist, ist die Bewegung des Geschmacksträgers 1 am Austritt aus dem Endabschnitt 10 identisch zu der Bewegung des Stranges 5, und zwar sowohl in der Ausrichtung in Bewegungsrichtung B als auch in der Höhe der Geschwindigkeit.Since the flavor carrier 1 is entrained by the strand 5 and is not driven by itself and the end portion 10 of the first feeder 4 is directed parallel to the strand 5, the movement of the flavor carrier 1 at the exit from the end portion 10 is identical to the movement of the strand fifth , both in the direction of movement B and in the height of the speed.
