Die Erfindung betrifft eine Einlegevorrichtung, die ausgebildet ist, stabförmige Artikel der Tabak verarbeitenden Industrie in einen Strang der Tabak verarbeitenden Industrie einzubringen oder an einen Strang der Tabak verarbeitenden Industrie anzulegen, mit wenigstens einer Mulde zur Aufnahme von stabförmigen Artikeln der Tabak verarbeitenden Industrie, insbesondere von Filtersegmenten, wobei die wenigstens eine Mulde eine Längserstreckung aufweist und wobei die Mulde eine Saugluftöffnung aufweist.The invention relates to an insertion device which is designed to introduce rod-shaped articles of the tobacco-processing industry into a strand of the tobacco-processing industry or to apply to a strand of the tobacco-processing industry, with at least one trough for receiving rod-shaped articles of the tobacco-processing industry, in particular Filter segments, wherein the at least one trough has a longitudinal extension and wherein the trough has a suction air opening.

Die Erfindung betrifft ferner eine Strangmaschine der Tabak verarbeitenden Industrie mit einer derartigen Einlegevorrichtung.The invention also relates to a rod machine in the tobacco processing industry with such an insertion device.

Bei entsprechenden Einlegevorrichtungen, die auch als Einlegeräder bekannt sind, werden mittels einer Rotationsbewegung stabförmige Artikel der Tabak verarbeitenden Industrie, insbesondere Filtersegmente, von einer queraxialen Förderrichtung in eine längsaxiale Förderrichtung übergeben, um so einen Strang aus diesen stabförmigen Artikeln der Tabak verarbeitenden Industrie bilden zu können.With corresponding insertion devices, which are also known as insertion wheels, rod-shaped articles of the tobacco processing industry, in particular filter segments, are transferred from a transverse axial conveying direction to a longitudinally axial conveying direction by means of a rotational movement in order to make a strand of these rod-shaped articles of tobacco manufacturing industry.

Eine derartige Vorrichtung ist beispielsweise aus DE 28 09 160 A1 bekannt. Dort dient ein Einlegerad dazu, queraxial auf das Einlegerad abgegebene Filterstopfen längsaxial in einen Strang, der auf einer Formatvorrichtung gebildet wird, abzugeben. Das dort gezeigte Einlegerad bzw. die dort gezeigte Einlegevorrichtung weist entsprechende Träger auf, die schwenkbar bzw. drehbar gelagert sind. Die Träger weisen Aufnahmen bzw. Mulden auf, in die die Filterstopfen eingebracht werden können und üblicherweise mit Saugluft gehalten werden. Hierzu ist ein Saugluftschlitz in der Aufnahmemulde vorgesehen.Such a device is for example off DE 28 09 160 A1 known. There, an insert wheel is used to deliver filter plugs dispensed transversely axially onto the insert wheel longitudinally axially into a strand that is formed on a format device. The insertion wheel shown there or the insertion device shown there has corresponding carriers which are pivotably or rotatably mounted. The carriers have receptacles or troughs into which the filter plugs can be inserted and are usually held with suction air. A suction air slot is provided in the receptacle for this purpose.

DE 25 34 666 A1 offenbart eine Vorrichtung zum Herstellen von kombinierten Filterstopfen für Filterzigaretten oder andere stabförmige Gegenstände der Tabak verarbeitenden Industrie. Es sind mehrere Saugluftöffnungen vorgesehen, um einen Stab festzuhalten. DE 25 34 666 A1 discloses an apparatus for manufacturing combined filter stoppers for filter cigarettes or other rod-shaped objects in the tobacco processing industry. Several suction air ports are provided to hold a stick in place.

DE 25 47 920 A1 offenbart ein Verfahren und eine Vorrichtung zum längsaxialen Aneinanderreihen von Filterstopfen auf einem Hüllmaterialstreifen. Auch hier sind mehrere Saugluftöffnungen zum Halten eines Stabes vorgesehen. DE 25 47 920 A1 discloses a method and a device for longitudinally lining up filter plugs on a strip of wrapping material. Here, too, several suction air openings are provided for holding a rod.

EP 2 641 486 A1 offenbart eine Vorrichtung zur Übertragung von Teilen von Filterstäben oder Zigarettenstäben. EP 2 641 486 A1 discloses a device for transferring parts of filter rods or cigarette rods.

Es ist nun festgestellt worden, dass es bei einem fehlenden stabförmigen Artikel bei der Übergabe zu unkontrollierten Übergaben kommen kann.It has now been found that if a rod-shaped article is missing, uncontrolled transfers can occur during the transfer.

Es ist daher Aufgabe der vorliegenden Erfindung, eine bekannte Einlegevorrichtung und eine bekannte Strangmaschine derart weiterzubilden, dass eine sehr hohe Prozesssicherheit bzw. eine sehr genaue Übergabe von stabförmigen Artikeln von einer queraxialen Förderrichtung in einen längsaxial geförderten Strang bzw. an einen längsaxial geförderten Strang ermöglicht ist.It is therefore the object of the present invention to develop a known insertion device and a known strand machine in such a way that very high process reliability or very precise transfer of rod-shaped articles from a transverse axial conveying direction into a longitudinally axially conveyed strand or to a longitudinally axially conveyed strand is possible .

Gelöst wird diese Aufgabe durch eine Einlegevorrichtung, die ausgebildet ist, stabförmige Artikel der Tabak verarbeitenden Industrie in einen Strang der Tabak verarbeitenden Industrie einzubringen oder an einen Strang der Tabak verarbeitenden Industrie anzulegen, mit wenigstens einer Mulde zur Aufnahme von stabförmigen Artikeln der Tabak verarbeitenden Industrie, insbesondere von Filtersegmenten, wobei die wenigstens eine Mulde eine Längserstreckung aufweist und wobei die Mulde eine Saugluftöffnung aufweist, die dadurch weitergebildet ist, dass wenigstens zwei Saugluftöffnungen in der Mulde vorgesehen sind, die durch einen Steg voneinander getrennt sind, wobei für jede Saugluftöffnung ein Saugluftkanal vorgesehen ist.This object is achieved by an insertion device which is designed to insert rod-shaped articles of the tobacco processing industry into a strand of the tobacco processing industry or to attach to a strand of the tobacco processing industry, with at least one trough for receiving rod-shaped articles of the tobacco processing industry, in particular of filter segments, wherein the at least one trough has a longitudinal extension and wherein the trough has a suction air opening, which is further developed in that at least two suction air openings are provided in the trough, which are separated from one another by a web, with a suction air channel being provided for each suction air opening is.

Durch die erfindungsgemäße Einlegevorrichtung wird das Risiko minimiert, dass bei einem fehlenden stabförmigen Artikel, beispielsweise Filtersegment, in einer Mulde der Einlegevorrichtung die Saugluft derart zusammenbricht, dass weitere in der Mulde angeordnete bzw. aufgenommene stabförmige Artikel nicht mehr gehalten werden können bzw. nicht mehr präzise gehalten werden können, so dass diese möglicherweise an falschen Stellen in den Strang eingelegt oder an den Strang angelegt werden. Hierdurch kann es insbesondere zu einem Strangbruch und einem Maschinenstopp kommen. Um den Einfluss eines fehlenden stabförmigen Artikels, beispielsweise eines fehlenden Filtersegments, für den Prozess zu reduzieren, werden wenigstens zwei mit einem Steg voneinander getrennte Saugluftöffnungen vorgesehen.The insertion device according to the invention minimizes the risk that if a rod-shaped article, for example a filter segment, is missing in a recess of the insertion device, the suction air collapses in such a way that further rod-shaped articles arranged or received in the recess can no longer be held or no longer precisely can be held so that they may be inserted in the wrong places in the strand or attached to the strand. In particular, this can lead to a strand break and a machine stop. In order to reduce the influence of a missing rod-shaped article, for example a missing filter segment, on the process, at least two suction air openings separated from one another by a web are provided.

Hierbei sind die Saugluftöffnungen vorzugsweise vollständig voneinander durch den jeweiligen Steg getrennt bzw. sind die Saugluftöffnungen nicht miteinander verbunden.In this case, the suction air openings are preferably completely separated from one another by the respective web or the suction air openings are not connected to one another.

Vorzugsweise weist die Mulde eine Auflagefläche auf, in der ein in die Mulde eingebrachter stabförmiger Artikel anliegt, wobei der Steg, insbesondere längsaxial, mit der Anlagefläche fluchtet, derart, dass ein in die Mulde eingebrachter stabförmiger Artikel an dem Steg anliegt.The trough preferably has a support surface in which a rod-shaped article placed in the trough rests, the web, in particular longitudinally axially, being aligned with the contact surface such that a bar-shaped article placed in the trough lies against the web.

Vorzugsweise ist der Steg oder sind die Stege an die Kontur der Mulde angepasst, insbesondere von deren Tiefe her mit der restlichen Kontur der Mulde, insbesondere längsaxial, fluchtend ausgelegt. Bei Vorsehen einer im Querschnitt kreisabschnittsförmigen Mulde ist beispielsweise der Steg auch kreisabschnittsförmig im Querschnitt. Es können auch andere Formen vorgesehen sein. Vorzugsweise wird eine Form zu wählen sein, die an die Form der stabförmigen Artikel angepasst ist, wobei insbesondere eine komplementäre Form der Mulde bzw. der Stege zu den stabförmigen Artikeln, die transportiert werden sollen bzw. übergeben werden sollen, vorgesehen ist.The web or the webs are preferably adapted to the contour of the trough, in particular designed to be aligned in terms of their depth with the remaining contour of the trough, in particular longitudinally axially. If a trough is provided that is circular segment-shaped in cross section, the web is also, for example, circular segment-shaped in cross section. Other shapes can also be provided. A shape should preferably be selected which is adapted to the shape of the rod-shaped article, in particular a complementary shape of the trough or the webs to the rod-shaped articles which are to be transported or to be transferred is provided.

Vorzugsweise ist die wenigstens eine Mulde auf einer Gondel angeordnet, wobei bei einer Rotation der Einlegevorrichtung um eine Rotationsachse eine Bewegung, insbesondere Verschwenkung, der Gondel vorgesehen ist, die für eine parallele Ausrichtung der wenigstens einen Mulde sorgt.The at least one trough is preferably arranged on a gondola, with a movement, in particular pivoting, of the gondola being provided when the insertion device rotates about an axis of rotation, which ensures a parallel alignment of the at least one trough.

Im Rahmen der Erfindung kann für das Wort Gondel auch Träger verwendet werden.In the context of the invention, carriers can also be used for the word gondola.

Die Rotationsachse der Gondel ist vorzugsweise parallel zu der Rotationsachse der Einlegevorrichtung.The axis of rotation of the gondola is preferably parallel to the axis of rotation of the insertion device.

Vorzugsweise weist die Einlegevorrichtung mehrere Gondeln auf. Die Gondeln können mit einer Mulde versehen sein, um beispielsweise stabförmige Artikel in einen Strang abzugeben. Es können allerdings auch zwei oder mehr nebeneinander, vorzugsweise parallel nebeneinander, angeordnete Mulden je Gondel vorgesehen sein, um zwei oder mehr Stränge mit stabförmigen Artikeln der Tabak verarbeitenden Industrie, insbesondere gleichzeitig, zu versorgen.The insertion device preferably has several gondolas. The gondolas can be provided with a trough, for example in order to deliver rod-shaped articles in a strand. However, two or more troughs arranged next to one another, preferably parallel to one another, can be provided for each gondola in order to supply two or more strings with rod-shaped articles of the tobacco processing industry, in particular simultaneously.

Vorzugsweise ist jede Saugluftöffnung einer Gondel einzeln schaltbar. Zum Schalten kann beispielsweise ein Ventil vorgesehen sein bzw. kann für jede Saugluftöffnung einzeln ein Ventil vorgesehen sein. Durch das Schalten ist die Saugluft zu- bzw. abschaltbar. Hierdurch ist eine sehr hohe Prozesssicherheit ermöglicht.Each suction air opening of a nacelle can preferably be switched individually. A valve can be provided for switching, for example, or a valve can be provided individually for each suction air opening. By the The suction air can be switched on or off. This enables a very high level of process reliability.

Wenn ein entsprechend großer Saugluftvorrat vorgesehen ist, kann allerdings auch unter Umständen auf das einzelne Schalten der Saugluftöffnungen verzichtet werden, da bei einem entsprechend großen Saugluftvorrat bzw. Saugluftreservoir ein Verlust von Saugluft über einen getrennten Saugluftkanal und eine getrennte Saugluftleitung zu dem Saugluftvorrat hin keinen ins Gewicht fallenden Verlust an Saugluft im Saugluftvorrat erzeugt.If a correspondingly large suction air supply is provided, the individual switching of the suction air openings can also be dispensed with under certain circumstances, since with a correspondingly large suction air supply or suction air reservoir, a loss of suction air via a separate suction air duct and a separate suction air line to the suction air supply is of no consequence falling loss of suction air generated in the suction air supply.

Das oder die Ventile können vorzugsweise in jeder Gondel angeordnet sein oder in einer Saugluftleitung oder mehreren Saugluftleitungen in einer Einlegevorrichtung angeordnet sein. Die Ventile können auch einer Einlegevorrichtung vorgeschaltet bzw. entfernt von der Einlegevorrichtung angeordnet sein. Es kann auch vorgesehen sein, dass ein Ventil eine erste Saugluftöffnung in einer ersten Gondel und einer zweiten Gondel zu- und abschalten kann und entsprechend ein zweites Ventil eine zweite Saugluftöffnung einer ersten Gondel und eine zweite Saugluftöffnung einer zweiten Gondel zu- und abschalten kann und entsprechend für weitere Saugluftöffnungen einer oder mehrerer Gondeln ein oder mehrere Ventile vorgesehen sind. Dieses wird im Zusammenhang mit den Figuren noch näher erläutert.The valve or valves can preferably be arranged in each nacelle or can be arranged in a suction air line or several suction air lines in an insertion device. The valves can also be arranged upstream of an insertion device or at a distance from the insertion device. It can also be provided that a valve can switch a first suction air opening in a first nacelle and a second nacelle on and off and correspondingly a second valve can switch a second suction air opening in a first nacelle and a second suction air opening in a second nacelle on and off and accordingly one or more valves are provided for further suction air openings of one or more gondolas. This is explained in more detail in connection with the figures.

Vorzugsweise ist für jeden stabförmigen Artikel eine Saugluftöffnung vorgesehen, wobei hierbei insbesondere der stabförmige Artikel in die Mulde einbringbar ist oder eingebracht wird.A suction air opening is preferably provided for each rod-shaped article, with the rod-shaped article in particular being or being introduced into the trough.

Die Aufgabe wird ferner durch eine Strangmaschine der Tabak verarbeitenden Industrie mit einer erfindungsgemäßen Einlegevorrichtung gelöst, wobei mittels der Einlegevorrichtung stabförmige Artikel auf eine Formatvorrichtung oder eine Fördervorrichtung auflegbar sind oder aufgelegt werden, so dass sich ein Strang aus stabförmigen Artikeln bildet.The object is also achieved by a rod machine of the tobacco processing industry with an insertion device according to the invention, wherein rod-shaped articles can be or are placed on a format device or a conveyor device by means of the insertion device, so that a rod is formed from rod-shaped articles.

Vorzugsweise ist die wenigstens eine Mulde parallel zu dem Strang oder der Formatvorrichtung angeordnet.The at least one trough is preferably arranged parallel to the strand or the format device.

Vorzugsweise ist ein Saugluftvorrat vorgesehen, von dem die Saugluftkanäle mit Saugluft gespeist werden oder mit Saugluft speisbar sind.A suction air supply is preferably provided, from which the suction air ducts are fed with suction air or can be fed with suction air.

Vorzugsweise ist jedem Saugluftkanal einer Gondel ein Ventil zugeordnet. Vorzugsweise kann ein Ventil für jeweils eine Saugluftleitung mehrerer Gondeln vorgesehen sein.A valve is preferably assigned to each suction air duct of a nacelle. Preferably, a valve can be provided for each suction air line of several gondolas.

Bei der Übergabe von stabförmigen Artikeln, insbesondere Filtersegmenten, aus einer Rotationsbewegung in eine längsaxiale Förderrichtung mithilfe eines Trägers oder einer Gondel, die eine Mulde aufweist, besteht das Risiko, dass bei einem oder mehreren fehlenden stabförmigen Artikeln bzw. Segmenten auf der Mulde die Halteluft zusammenbricht. Wenn sich der Unterdruck bzw. die Saugluft zum Halten der stabförmigen Artikel auf der Mulde zu stark reduziert, entsteht ein großes Prozessrisiko, da die weiteren stabförmigen Artikel bzw. Segmente nicht mehr auf oder in der Mulde gehalten werden können. Für diesen Fall können eine oder mehrere weitere Segmente aus der Mulde fallen und es zu einem Strangbruch und damit einem Maschinenstopp kommen.When transferring rod-shaped articles, in particular filter segments, from a rotational movement in a longitudinally axial conveying direction with the aid of a carrier or a gondola that has a trough, there is a risk that the holding air will collapse if one or more bar-shaped articles or segments are missing on the trough . If the negative pressure or the suction air for holding the rod-shaped articles on the trough is reduced too much, a great process risk arises, since the further bar-shaped articles or segments can no longer be held on or in the trough. In this case, one or more further segments can fall out of the trough and lead to a strand break and thus a machine stop.

Erfindungsgemäß werden in die Mulde zwei oder mehrere separate Saugkanäle oder Saugluftöffnungen eingebracht.According to the invention, two or more separate suction channels or suction air openings are introduced into the trough.

Durch die Kanäle wird verhindert, dass der Unterdruck bzw. die Saugluft komplett in der Mulde bzw. der Gondel zusammenbricht und verbleibende Segmente bzw. stabförmige Artikel werden somit prozesssicher gehalten. Die Saugluftöffnungen oder die Saugluftkanäle können gleichmäßig bzw. gleich groß verteilt oder ausgebildet sein oder von deren Größe her auf die einzelnen aufzunehmenden bzw. zu fördernden stabförmigen Artikel angepasst werden. Einem größeren stabförmigen Artikel kann beispielsweise eine größere Saugluftöffnung zugeordnet werden als einem kleineren stabförmigen Artikel. Entsprechend können schwerere stabförmige Artikel eine größere Saugluftöffnung erhalten, als leichtere stabförmige Artikel.The channels prevent the negative pressure or the suction air from collapsing completely in the trough or the gondola, and remaining segments or rod-shaped articles are thus held in a process-reliable manner. The suction air openings or the suction air channels can be distributed or designed uniformly or equally large or their size can be adapted to the individual rod-shaped articles to be picked up or conveyed. A larger rod-shaped article can, for example, be assigned a larger suction air opening than a smaller rod-shaped article. Correspondingly, heavier ones can be rod-shaped Articles have a larger suction air opening than lighter rod-shaped articles.

Ein zusätzlicher überraschender Effekt dieser Art der Muldenausbildung einer entsprechenden Einlegevorrichtung ist der, dass sich eine vergrößerte Reibfläche zwischen den stabförmigen Artikeln und der Mulde ergibt, was den Einlegeprozess in einem Strang oder an einen Strang verbessert. Durch die Stege in der Mulde wird eine zusätzliche höhere Stabilität erzielt. Vorzugsweise wird auch noch eine Kante, die in längsaxialer Richtung der Mulde die Mulde abschließt, versteift, um eine genaue Platzierung der stabförmigen Artikel in den Strang oder an den Strang zu ermöglichen.An additional surprising effect of this type of trough design of a corresponding insertion device is that there is an enlarged friction surface between the rod-shaped articles and the trough, which improves the insertion process in a strand or on a strand. The bars in the trough provide additional stability. Preferably, an edge that closes off the trough in the longitudinal axial direction of the trough is also stiffened in order to enable the rod-shaped articles to be positioned precisely in the strand or on the strand.

In den Zeichnungen sind jeweils gleiche oder gleichartige Elemente und/oder Teile mit denselben Bezugsziffern versehen, so dass von einer erneuten Vorstellung jeweils abgesehen wird.In the drawings, the same or similar elements and / or parts are provided with the same reference numerals, so that they are not presented again.

Fig. 1 zeigt schematisch eine Ansicht einer Strangmaschine 21 der Tabak verarbeitenden Industrie. Beispielsweise ist eine Filterstrangmaschine gezeigt. Filtersegmente 11, 11' werden durch eine nicht dargestellte Übergabevorrichtung in Mulden 13 von Gondeln 17 einer Einlegevorrichtung 10 eingebracht. Die Einlegevorrichtung 10 rotiert in Pfeilrichtung um eine Rotationsachse 18. Die Gondeln 17 sind jeweils an Rotationsachsen 19 angebracht, so dass bei einer Rotation der Einlegevorrichtung 10 die Ausrichtung der Mulden 13 gleich bleiben, und zwar insbesondere parallel zum gebildeten Strang 12 bzw. einer Bahn der Formatvorrichtung 22. Fig. 1 shows schematically a view of a rod machine 21 of the tobacco processing industry. For example, a filter rod machine is shown. Filter segments 11, 11 ′ are introduced into troughs 13 of gondolas 17 of an insertion device 10 by a transfer device (not shown). The insertion device 10 rotates in the direction of the arrow about an axis of rotation 18. The gondolas 17 are each attached to rotation axes 19 so that when the insertion device 10 rotates, the alignment of the troughs 13 remains the same, in particular parallel to the strand 12 formed or a path of the Format device 22.

Die aufgenommenen Filtersegmente 11, 11' werden längsaxial in einen Strang 12 übergeben. Hierzu werden die Filtersegmente 11, 11' auf einen Umhüllungsmaterialstreifen 35, der auf einem Formatband 34 aufgebracht ist, aufgelegt. Das Formatband 34 bewegt sich in Pfeilrichtung, d.h. in Fig. 1 von rechts nach links, durch die Formatvorrichtung 22, so dass in der Formatvorrichtung 22 ein Umhüllungsmaterialstreifen 35 um den Strang 12 gewickelt wird, wie üblich mit einem Kleber versehen wird und geschlossen wird. Anschließend wird der Strang 12 durch eine Schneidvorrichtung 33 in Filterstäbe gewünschter Gebrauchslänge, beispielsweise zweifacher Gebrauchslänge, abgelängt.The filter segments 11, 11 ′ that are picked up are transferred into a strand 12 along the axis. For this purpose, the filter segments 11, 11 ′ are placed on a wrapping material strip 35 which is applied to a format tape 34. The format tape 34 moves in the direction of the arrow, ie in Fig. 1 from right to left, through the format device 22, so that a wrapping material strip 35 is wrapped around the strand 12 in the format device 22, is provided with an adhesive as usual and is closed. Subsequently, the strand 12 is cut to length by a cutting device 33 into filter rods of the desired useful length, for example twice the useful length.

Die erfindungsgemäße Einlegevorrichtung 10 weist Gondeln 17 auf, die in Fig. 2 in einer Darstellung von unten schematisch gezeigt sind. Es ist eine Mulde 13 gezeigt, die eine Anlagefläche 16 aufweist, an die die stabförmigen Artikel 11, 11' angelegt werden. Es sind zudem vier Saugluftöffnungen 14, 14', 14", 14'" gezeigt, die jeweils mit Stegen 15, 15', 15" voneinander getrennt sind. Die Stege 15, 15' 15" sind vorzugsweise auf der gleichen Höhe wie die Anlagefläche 16 bzw. fluchten mit dieser, so dass für den Fall, dass wenn Filtersegmente 11, 11' in die Mulde 13 eingebracht sind, im Wesentlichen keine Saugluft an den Stegen 15, 15', 15" vorbeigesaugt wird, da die Filtersegmente 11, 11' entsprechend eine Abdichtung mit der Anlagefläche 16 ergeben.The insertion device 10 according to the invention has gondolas 17 which are shown in FIG Fig. 2 are shown schematically in a representation from below. A trough 13 is shown which has a contact surface 16 against which the rod-shaped articles 11, 11 'are applied. There are also four suction air openings 14, 14 ', 14 ", 14'" shown, each with webs 15, 15 ', 15 " are separated from each other. The webs 15, 15 '15 "are preferably at the same height as the contact surface 16 or are aligned with it, so that in the event that when filter segments 11, 11' are introduced into the trough 13, essentially no suction air is at the Web 15, 15 ', 15 "is sucked past, since the filter segments 11, 11' result in a seal with the contact surface 16 accordingly.

Die Saugluftöffnungen 14, 14', 14", 14'" sind mit Saugluftkanälen 20, 20', 20", 20'" verbunden, die jeweils getrennt in der Gondel 17 verlaufen. Die entsprechende Trennung dieser Saugluftkanäle 20-20'" ist in Fig. 3 noch einmal dargestellt, in der schematisch ein Schnitt durch eine entsprechende Gondel 17 gezeigt ist, und zwar in etwa entlang der Linie A-A aus Fig. 2. Es ist erkennbar, dass die Saugluftkanäle 20-20'" durch Wände voneinander getrennt sind.The suction air openings 14, 14 ′, 14 ″, 14 ′ ″ are connected to suction air ducts 20, 20 ′, 20 ″, 20 ′ ″ which each run separately in the nacelle 17. The corresponding separation of these suction air channels 20-20 '"is in Fig. 3 shown once again, in which a section through a corresponding gondola 17 is shown schematically, approximately along the line AA from Fig. 2 . It can be seen that the suction air ducts 20-20 '"are separated from one another by walls.

Fig. 4 zeigt schematisch ein Saugluftdiagramm gemäß der Erfindung. Es ist ein relativ großer Saugluftvorrat 30 gezeigt, von dem vier Saugluftleitungen 32-32"' abzweigen. An diese Saugluftleitungen 32-32'" schließen sich Ventile 31-31'" an, an die sich die Saugluftkanäle 20-20" anschließen und daran dann eine Mulde 13, die mit entsprechenden Saugluftöffnungen 14-14'" versehen ist. Fig. 4 shows schematically a suction air diagram according to the invention. A relatively large suction air supply 30 is shown, from which four suction air lines 32-32 "'branch off. Valves 31-31'" are connected to these suction air lines 32-32 '", to which the suction air ducts 20-20" are connected then a trough 13 which is provided with corresponding suction air openings 14-14 '".

Die Ventile 31-31'" können auch in den Saugluftleitungen 32-32'" angeordnet sein oder an dem Saugluftvorrat 30, bevor die Saugluftleitungen 32-32'" beginnen.The valves 31-31 '"can also be arranged in the suction air lines 32-32'" or on the suction air supply 30 before the suction air lines 32-32 '"begin.

Die Saugluftleitungen 32-32'" können auch abgezweigt sein, und zwar in der Einlegevorrichtung 10 abgezweigt sein und mehrere Gondeln 17 jeweils mit Saugluft versorgen bzw. mehrere Saugluftkanäle 20-20'" mit Saugluft versorgen. Die Ventile 31-31'" können in der jeweiligen Gondel 17 selbst angeordnet sein oder zwischen der jeweiligen Gondel 17 und dem Saugluftvorrat 30.The suction air lines 32-32 '"can also be branched off, namely in the insertion device 10 and supply several gondolas 17 each with suction air or supply several suction air channels 20-20'" with suction air. The valves 31-31 ′ ″ can be arranged in the respective gondola 17 itself or between the respective gondola 17 and the suction air supply 30.

Bei einem ausreichend großen Saugluftvorrat 30 kann auf die Ventile 31-31'" auch vollständig oder wenigstens zum Teil verzichtet werden.With a sufficiently large suction air supply 30, the valves 31-31 '" can also be completely or at least partially waived.

Alle genannten Merkmale, auch die den Zeichnungen allein zu entnehmenden sowie auch einzelne Merkmale, die in Kombination mit anderen Merkmalen offenbart sind, werden allein und in Kombination als erfindungswesentlich angesehen. Erfindungsgemäße Ausführungsformen können durch einzelne Merkmale oder eine Kombination mehrerer Merkmale erfüllt sein.
