In der tabakverarbeitenden Industrie besteht allerdings der Wunsch, Multisegmentfilter herzustellen, die aus verschiedenen Segmenten bestehen, wie z. B. aus unterschiedlichen Materialien. Diese Materialien sind beispielsweise Zelluloseacetat, Papier, Vlies, Granulat, gesonderte Elemente, Hohlzylinder oder Hohlkammern und Kapseln und dergleichen. Derartige Multisegmentfilter, die im Rahmen dieser Erfindung auch den Begriff "Mehrfachfilter" umfassen, werden nach Ausbilden von Gruppen von Filtersegmenten beispielsweise in einem Strangverfahren mit Umhüllungsmaterial, wie beispielsweise Papier umhüllt, und dann in zwei-, vier- oder sechsfach lange Filterstäbe zerteilt, um weiterverarbeitet zu werden.However, there is in the tobacco processing industry the desire to manufacture multi-segment filters from different segments exist, such as B. from different Materials. These materials are, for example Cellulose acetate, paper, fleece, granules, separate elements, hollow cylinders or hollow chambers and Capsules and the like. Such multi-segment filters, which in the context of this invention also the term "multiple filter" include, after forming groups of filter segments, for example in a strand process with wrapping material such as paper wrapped, and then in two, four or six times long Filter rods cut up for further processing.

Aus der deutschen Patentanmeldung DE 101 55 292.0 ist eine Einrichtung zum Zusammenstellen von Gruppen von Filtersegmenten zur Herstellung von Multisegmentfiltern der tabakverarbeitenden Industrie in einem Strangverfahren bekannt, wobei je Multisegmentfilter wenigstens' zwei unterschiedliche Arten von Filtersegmenten vorgesehen sind und wobei die Einrichtung in einer Mehrzahl von selbständigen Funktionseinheiten unterteilbar ist.

Hierdurch ist eine große Variabilität bei der Multisegmentfilterherstellung möglich.This is a great variability in multi-segment filter production possible.

Aufgabe der vorliegenden Erfindung ist es, Filtersegmente für einen Multisegmentfilter bereitzustellen, die auf einfache Weise variabel konfektionierbar und herstellbar sind, wobei der apparative Aufwand sehr gering gehalten werden soll.The object of the present invention is filter segments for a multi-segment filter, which are easy to assemble and variable are producible, the equipment required very much should be kept low.

Diese Aufgabe wird gelöst mittels des Verfahrens der eingangs genannten Art, daß dadurch weitergebildet ist, daß in die Filtersegmente vor ihrer Zustellung zur Gruppe von Filtersegmenten ein Medium eingebracht wird. Während der laufenden Produktion von Multisegmentfiltern wird eine Substanz in die Filtersegmente injiziert, die in einem nachfolgenden Schritt für die Zusammenstellung eines Multisegmentfilters verwendet werden. Durch die Zugabe von Stoffen werden die Filtersegmente mit bestimmten und gewünschten Eigenschaften ausgestattet, so daß die Filtersegmente leicht an die Anforderungen an einen herzustellenden Multisegmentfilter angepaßt werden können.This object is achieved using the method of type mentioned at the outset that this is further developed that in the filter segments before their delivery for Group of filter segments a medium is introduced. During the ongoing production of multi-segment filters a substance is injected into the filter segments that in a subsequent step for the compilation a multi-segment filter can be used. Through the The filter segments are determined with the addition of substances and desired properties, so that the filter segments easily meet the requirements a multisegment filter to be manufactured can be adapted can.

Eine alternative Lösung der Aufgabe besteht bei dem Verfahren der eingangs genannten Art darin, daß zunächst in Filterstäbe ein Medium eingebracht wird und in einem nachfolgenden Schritt die Filterstäbe in Filtersegmente geschnitten werden. Hierbei werden die Filterstäbe aus einem Magazin, z. B. eines Moduls entnommen und vor ihrer Aufteilung in mehrere Segmente mit einer Substanz versehen. Dies geschieht auch während der laufenden Produktion von Multisegmentfiltern.An alternative solution to the problem is with Process of the type mentioned in that initially a medium is introduced into filter rods and in one following step the filter rods in filter segments get cut. Here, the filter rods are made a magazine, e.g. B. taken from a module and before their division into several segments with one substance Mistake. This also happens during the running Production of multi-segment filters.

Insbesondere wird das Medium während des Transports der Filterstäbe oder der Filtersegmente, insbesondere auf einer Fördertrommel oder Funktionstrommel, eingebracht.

Seitlich von der Aufnahmemulde 28 bzw. dem' Filtersegment 1 ist eine horizontal bewegbare Sprühdüse 2 angeordnet. Die Sprühdüse 2 verfügt über einen Kanal 41, der in einen Düsenkopf 42 mündet. Der Durchmesser des Düsenkopfs 42 entspricht im wesentlichen dem Durchmesser der Bohrung 30 des Anschlages 29.The functional drum 18 also has a side a stop 29 in the area of the deposited filter segment 1 has a bore 30. Laterally from the Receiving trough 28 or the 'filter segment 1 is one horizontally movable spray nozzle 2 arranged. The spray nozzle 2 has a channel 41 that goes into a nozzle head 42 opens. The diameter of the nozzle head 42 corresponds essentially to the diameter of the bore 30 of the stop 29.

Nach Einlegen wird das Filtersegment 1 mittels eines Fixierarms 4 in der Aufnahmemulde 28 fest umschlossen (Fig. 2b). Der Fixierarm 4 ist vorzugsweise schwenkbar an der Funktionstrommel 18 ausgebildet. Ferner verfügt der Fixierarm 4 über einen seitlichen Anschlag 34, so daß das abgelegte Filtersegment 1 in einer exakten Position festgehalten wird.After inserting the filter segment 1 by means of a Fixing arms 4 firmly enclosed in the receiving trough 28 (Fig. 2b). The fixing arm 4 is preferably pivotable formed on the functional drum 18. Also has the fixing arm 4 via a side stop 34, so that the filed filter segment 1 in an exact Position is held.

Während oder nach der Fixierung des Filtersegments 1 wird die Sprühdüse 2 seitlich an das Filtersegment 1 herangefahren und eine im Kanal 41 eingebrachte, genau dosierte Menge eines Mediums 3 in das Filtersegment 1 eingeblasen (Fig. 2 c). Als Medium eignen sich Substanzen, wie z.B. Zeolithe, Aktivkohle, Geschmacks-/Aromastoffe oder Vitamine. In einem nachfolgenden Schritt (Fig. 2d) wird die Sprühdüse 2 vom Filtersegment 1 weggefahren und in einem weiteren Schritt die Fixierung des Filtersegments 1 gelöst (Fig. 2e). Nachfolgend wird das hergestellte Filtersegment 1 an die Transporttrommel 23 übergeben (Fig. 2f).During or after fixing the filter segment 1 the spray nozzle 2 is laterally connected to the filter segment 1 drove up and one in channel 41, exactly dosed amount of a medium 3 in the filter segment 1 blown in (Fig. 2 c). Substances are suitable as medium, such as. Zeolites, activated carbon, flavorings / aromas or vitamins. In a subsequent step (Fig. 2d), the spray nozzle 2 from the filter segment 1st moved away and in a further step the fixation the filter segment 1 solved (Fig. 2e). Below is the filter segment 1 produced to the transport drum 23 passed (Fig. 2f).

Der Sprühdorn 5 verfügt über einen Kanal 43 und eine Nadelspitze 44, die in das Filtersegment 1 längsaxialparallel eingeführt wird. Nach Eindringen der Nadelspitze 44 in das Filtersegment 1 wird das Medium in das Innere des Filtersegments 1 eingebracht. Im Rahmen der Erfindung ist es vorstellbar, daß der Sprühdorn 5 auch mehrere Nadelspitzen verfügt oder die Nadelspitze 44 über weitere (seitliche) Austrittsöffnungen entlang des Kanals 44 verfügt, um eine gleichmäßige Verteilung der Substanz im Filtersegment 1 zu erreichen.The process sequences are shown in FIGS. 3a to 3f analogous to the process sequences in FIGS. 2a to 2h shown, but with the difference that instead of a spray nozzle 2 (Fig. 2a to 2f) a spray mandrel 5 is used. The spray mandrel 5 has one Channel 43 and a needle tip 44 that is in the filter segment 1 is introduced parallel to the longitudinal axis. After intrusion the needle tip 44 in the filter segment 1 the medium is introduced into the interior of the filter segment 1. Within the scope of the invention it is conceivable that the spray mandrel 5 also has several needle tips or the needle tip 44 via further (lateral) outlet openings along the channel 44 has a uniform Distribution of the substance in filter segment 1 too to reach.

In den Fig. 4a bis 4f wird ein Mehrfach-Filtersegment 7 mit einem Medium erfindungsgemäß beaufschlagt. Das Mehrfach-Filtersegment 7 verfügt über äußere Stöpsel 71, zwischen den eine Hohlkammer 72 angeordnet ist. Diese Hohlkammer 72 des Mehrfach-Filtersegments 7 wird mittels des Sprühdorns 5 mit einer Substanz befüllt. Der Sprühdorn 5 wird hierbei exakt mit seiner Nadelspitze 44 in der Hohlkammer 72 positioniert. Alternativ können in analoger Weise auch Hohlkammern von Filterstäben mit einem Medium befüllt werden.A multiple filter segment 7 is shown in FIGS. 4a to 4f acted upon with a medium according to the invention. The Multiple filter segment 7 has outer plugs 71, between which a hollow chamber 72 is arranged. This Hollow chamber 72 of the multiple filter segment 7 is by means of of the spray mandrel 5 filled with a substance. The spray mandrel 5 is precisely with its needle tip 44 in the hollow chamber 72 positioned. Alternatively, in analogous also with hollow chambers of filter rods be filled in a medium.

In einer Weiterbildung der Erfindung werden von beiden Seiten in die Filtersegmente Substanzen eingebracht. In a further development of the invention, both Pages inserted into the filter segments substances.
