Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Packungen mit durch Klebung verbundenen Faltlappen, insbesondere Zigaretten-Packungen aus Karton, die unmittelbar nach Fertigstellung einem ersten und anschliessend einem zweiten Trockenrevolver zuführbar sind, die jeweils Taschen zur zeitweiligen Aufnahme der Packungen aufweisen.The invention relates to a device for producing packs with folding flaps connected by gluing, in particular cigarette packs made of cardboard, which can be fed to a first and then a second drying turret immediately after completion, each having pockets for temporarily holding the packs.

Eine Vorrichtung dieser Art ist bekannt durch die DE-A-30 46 065. Diese Vorveröffentlichung beschreibt eine Verpackungsmaschine für Zigaretten, bei der die fertigen Packungen in einen Trockenrevolver gefördert werden, der aus zwei axial hintereinander angeordneten Zellenrädern besteht. Jedes dieser Zellenräder ist längs des Umfangs mit im Querschnitt geschlossenen Taschen, je zur Aufnahme einer Packung, versehen. Die fertigen Packungen werden zunächst in das innerste Zellenrad und nach nahezu vollständiger Umdrehung desselben in Axialrichtung in eine Tasche des zweiten Zellenrades eingeschoben.A device of this type is known from DE-A-30 46 065. This prior publication describes a packaging machine for cigarettes in which the finished packs are conveyed into a drying turret which consists of two cell wheels arranged axially one behind the other. Each of these cellular wheels is provided with pockets closed in cross section along the circumference, each for receiving a pack. The finished packs are first inserted into the innermost cell wheel and, after almost complete rotation in the axial direction, into a pocket of the second cell wheel.

Durch die beiden Zellenräder des Trockenrevolvers wird zwar die insgesamt zur Verfügung stehende Trockenzeit für die Packungen zum Abbinden von Leimstellen erhöht. Es hat sich aber als nachteilig erwiesen, dass die im ersten Zellenrad vorgetrockneten Packungen in Einzeltaschen, die in den Abmessungen denjenigen der Packungen entsprechen, eines zweiten Zellenrades eingeschoben werden müssen. Es besteht die Gefahr, dass dadurch in Einzelfällen die bereits teilweise ausgehärteten Leimverbindungen der Faltlappen verschoben werden.The two cell wheels of the drying turret increase the total drying time available for the packs for setting glue spots. However, it has proven to be disadvantageous that the packs predried in the first cell wheel must be inserted into individual pockets of a second cell wheel, the dimensions of which correspond to those of the packs. There is a risk that in some cases the already partially hardened glue connections of the folding flaps will be displaced.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art dahingehend weiterzuentwickeln und zu verbessern, dass die Stabilisierung von durch Klebung miteinanderverbundenen Faltlappen bei hoher Leistung der Verpackungsmaschine und bei hinsichtlich der Klebung kritischen Packungen, insbesondere aus metallbeschichtetem Verpackungsmaterial, ohne Beeinträchtigung der im ersten Trockenrevolver vorgetrockneten Leimverbindungen möglich ist.The invention is based on the object of further developing and improving a device of the type mentioned at the outset such that the stabilization of folding tabs connected to one another by adhesive at high performance of the packaging machine and in the case of packs critical with regard to the adhesive, in particular of metal-coated packaging material, without impairing the first Dry revolver pre-dried glue connections is possible.

Zur Lösung dieser Aufgabe ist die erfindungsgemässe Vorrichtung dadurch gekennzeichnet, dass die Taschen des ersten Trockenrevolvers zur Aufnahme jeweils einer Packung bestimmt sind, während die Taschen des zweiten Trockenrevolvers zur Aufnahme einer Gruppe von Packungen ausgelegt sind, und dass die Packungen vom ersten Trockenrevolver durch einen Zuförderer zum zweiten Trockenrevolver transportierbar sind, wobei dem Zuförderer eine Stauvorrichtung zugeordnet ist, mittels der die für eine Packungs- gruppe bestimmte Anzahl von Packungen in die zugeordnete Tasche des zweiten Trockenrevolvers freigebbar ist.To achieve this object, the device according to the invention is characterized in that the pockets of the first drying turret are each intended for receiving a pack, while the pockets of the second drying turret are designed for receiving a group of packs, and in that the packs from the first drying turret are designed by a feed conveyor can be transported to the second drying turret, the feeder being assigned a stowage device by means of which the number of packages intended for a packing group can be released into the assigned pocket of the second drying turret.

Der Erfindung liegt die Erkenntnis zugrunde, dass nach der verhältnismässig langen Verweildauer der Packungen im ersten Trockenrevolver in Taschen, die verhältnismässig genau auf die Abmessungen einzelner Packungen abgestellt sind, im zweiten Trockenrevolver lediglich eine ausreichende Verweildauer zum Nachtrocknen der Pakkungen ohne formgebende Einwirkung erforderlich ist. Aus diesem Grunde ist der zweite Trokkenrevolver mit Taschen versehen, die eine Gruppe von Packungen aufzunehmen vermag.The invention is based on the knowledge that after the relatively long dwell time of the packs in pockets in the first drying turret, which are geared to the dimensions of individual packs relatively precisely, only a sufficient dwell time is required in the second drying turret for the packages to dry without any shaping action. For this reason, the second drying turret is provided with pockets that can hold a group of packs.

Der zweite Trockenrevolver kann dadurch im Aufbau einfacher und mit geringerem Durchmesser ausgebildet sein.As a result, the structure of the second drying turret can be simpler and of smaller diameter.

Auf dem Weg vom ersten zum zweiten Trokkenrevolver werden die Packungen nach einem weiteren Vorschlag der Erfindung durch den Zuförderer so gehalten, dass die vorgetrockneten Leimverbindungen von Seitenlappen der Packungen durch Gurte des Zuförderers beaufschlagt sind.On the way from the first to the second drying turret, according to a further proposal of the invention, the packs are held by the feed conveyor in such a way that the predried glue connections from side tabs of the packs are acted upon by belts of the feed conveyor.

Das in den Zeichnungen dargestellte Ausführungsbeispiel betrifft eine Verpackungsmaschine bzw. Teile derselben zum Herstellen von quaderförmigen Zigaretten-Packungen 10. Vorzugsweise handelt es sich dabei um Klappschachteln (Hinge-Lid-Packungen) aus dünnem Karton. Der Teil der Verpackungsmaschine, der sich auf die Herstellung der eigentlichen Packung 10 bezieht, ist im einzelnen nicht dargestellt, entspricht jedoch vorzugsweise der Ausführungsform gemäss DE-OS 24 40 006.The exemplary embodiment shown in the drawings relates to a packaging machine or parts thereof for the production of cuboid-shaped cigarette packs 10. These are preferably hinged boxes (hinge-lid packs) made of thin cardboard. The part of the packaging machine which relates to the production of the actual package 10 is not shown in detail, but preferably corresponds to the embodiment according to DE-OS 24 40 006.

Die Zigaretten-Packungen 10 sind so ausgebildet, dass im Bereich schmaler Seitenflächen 11 einander überdeckende Seitenlappen durch Kleber miteinander verbunden sind. Die Zigaretten-Packungen 10 mit noch nicht ausgehärtetem Kleber werden auf einer Packungsbahn 12 zugefördert, durch Anheben einem Übergaberevolver 13 zugeführt und von diesem an einen ersten Trokkenrevolver 14 übergeben. Dieser ist vorzugsweise so ausgebildet wie in der DE-OS 26 32 968 beschrieben, nämlich mit einer Mehrzahl von radial gerichteten Taschen 15, je zur Aufnahme einer Zigaretten-Packung 10. Die Taschen 15 sind so ausgebildet, dass ein formierender Druck auf die Zigaretten-Packungen 10 ausgeübt und dadurch deren quaderförmige Gestalt korrigiert und stabilisiert wird. Die Packungen werden zweckmässigerweise in diesem ersten Faltrevolver 14 leicht erwärmt.The cigarette packs 10 are designed in such a way that in the region of narrow side surfaces 11 side flaps which overlap one another are connected to one another by adhesive. The cigarette packs 10 with adhesive that has not yet cured are conveyed on a packing track 12, are fed to a transfer turret 13 by lifting and are transferred from the latter to a first drying turret 14. This is preferably designed as described in DE-OS 26 32 968, namely with a plurality of radially directed pockets 15, each for receiving a cigarette pack 10. The pockets 15 are designed so that a forming pressure on the cigarette Packs 10 exercised and thereby their cuboid shape is corrected and stabilized. The packs are used moderately warmed slightly in this first folding turret 14.

Nach einer nahezu vollständigen Drehung des Trockenrevolvers 14 werden die Packungen durch einen Ausstosser 16 aus den Taschen 15 ausgeschoben und in einen unmittelbar an den Trockenrevolver 14 anschliessenden Bandförderer eingeführt, der zugleich Zuförderer 17 für einen weiteren (zweiten) Trockenrevolver 18 ist.After an almost complete rotation of the drying turret 14, the packs are pushed out of the pockets 15 by an ejector 16 and inserted into a belt conveyor directly connected to the drying turret 14, which is also a feed conveyor 17 for a further (second) drying turret 18.

Der Zuförderer 17 besteht aus einem umlaufenden, endlosen Obergurt 19 und einem ebenfalls endlos umlaufenden Untergurt 20. Zwischen diesen finden die Zigaretten-Packungen 10 Aufnahme in einer Realtivstellung, bei der die langgestreckten Seitenflächen 11 nach unten und oben gerichtet sind, Stirnflächen 21 also zu den Seiten hinweisen.The feed conveyor 17 consists of an encircling, endless upper chord 19 and an endless encircling lower chord 20. Between these, the cigarette packs 10 are received in a real position, in which the elongated side faces 11 are directed downwards and upwards, that is to say end faces 21 Point out pages.

Die Zigaretten-Packungen 10 werden durch den Zuförderer 17 mit Abstand voneinander unmittelbar dem zweiten Trockenrevolver 18 zu und in Taschen 22 desselben eingefördert. Dabei werden durch Aufstauen der Zigaretten-Packungen 10 Packungsgruppen 23 gebildet, die je zur Aufnahme in einer Tasche 22 bestimmt sind. Bei dem vorliegenden Ausführungsbeispiel besteht jede einer Taschen 22 zugeordnete Packungsgruppe 23 aus vier Zigaretten-Packungen 10.The cigarette packs 10 are fed by the feed conveyor 17 at a distance from one another directly to the second drying turret 18 and into pockets 22 of the same. In this case, 10 pack groups 23 are formed by stowing the cigarette packs, which are each intended to be received in a pocket 22. In the present exemplary embodiment, each pack group 23 assigned to a pocket 22 consists of four cigarette packs 10.

Der Trockenrevolver 18 ist in einer um 90° versetzten Ebene zum ersten Trockenrevolver 14 angeordnet, beide in aufrechten Ebenen. Die Taschen 22 des zweiten Trockenrevolvers 18 sind als in Axialrichtung durchgehende Kammern ausgebildet, durch die die Packungsgruppe 23 in Axialrichtung hindurchgeschoben wird. Jede Tasche besteht aus zwei Seitenwänden 24 und 25, von denen im vorliegenden Falle eine (Seitenwand 25) bewegbar ist. Diese ist Teil eines zweiarmigen Wandhebels 26, der um ein Drehlager 27 verschwenkt wird und dessen freier Stützarm mit einer Tastrolle 28 auf einer ortsfesten Kurvenscheibe 29 abgestützt ist. Eine (Zug-) Feder 30, die am freien Arm des Wandhebels 26 angreift, bewirkt, dass die Seitenwand 25 in Schliessstellung belastet wird. Im Bereich einer Beschikkungsstation 31 sowie einer Ausschubstation 32 werden die Seitenwände 25 jeweils durch Auflaufen der Tastrolle 28 auf eine Erhöhung der Kurvenscheibe 29 gegen die Spannung der Feder 30 geöffnet. Die radial aussenliegende Seite der Taschen 22 wird durch eine ortsfeste Ringwand 33 begrenzt. Auf der gegenüberliegenden Seite bildet eine geschlossene mit umlaufende Tragscheibe 34, an der auch die feststehenden Seitenwände 24 und die schwenkbaren Seitenwände 25 angebracht sind, die Begrenzung der Tasche 22. Die Packungen 10 werden zwischen den Seitenwänden 24 und 25 durch Festklemmen fixiert.The drying turret 18 is arranged in a plane offset by 90 ° to the first drying turret 14, both in upright planes. The pockets 22 of the second drying turret 18 are designed as continuous chambers in the axial direction, through which the packing group 23 is pushed in the axial direction. Each pocket consists of two side walls 24 and 25, one of which (side wall 25) is movable in the present case. This is part of a two-armed wall lever 26 which is pivoted about a pivot bearing 27 and the free support arm of which is supported on a stationary cam 29 by a feeler roller 28. A (tension) spring 30, which acts on the free arm of the wall lever 26, causes the side wall 25 to be loaded in the closed position. In the area of a loading station 31 and a push-out station 32, the side walls 25 are each opened by running the feeler roller 28 to raise the cam plate 29 against the tension of the spring 30. The radially outer side of the pockets 22 is delimited by a stationary ring wall 33. On the opposite side, a closed, circumferential support disk 34, to which the fixed side walls 24 and the pivotable side walls 25 are attached, forms the boundary of the pocket 22. The packs 10 are fixed between the side walls 24 and 25 by clamping.

Die durch den Zuförderer 17 in die sich in der Beschickungsstation 31 befindliche Tasche 22 transportierten Zigaretten-Packungen 10 laufen auf der gegenüberliegenden Seite gegen einen Taschenanschlag 35. Dieser ist bei dem vorliegenden Ausführungsbeispiel als zweiarmiger Hebel ausgebildet mit einem Anschlagvorsprung 36, der von der Austrittsseite her in die Tasche 22 hineinragt. Ein Schwenklager 37 ist an einer feststehenden Haltescheibe 38 angebracht. Ein von dem Anschlagvorsprung 36 anliegender Schenkel 39 des Taschenanschlags 35 ist mit einer Laufrolle 40 auf einer topfförmigen Kurvenscheibe 41 abgestützt. Eine am Taschenanschlag 35 angreifende (Zug-) Feder 42 bewirkt, dass die Laufrolle 40 ständig an der Kurvenscheibe 41 anliegt, der Anschlagvorsprung 36 demnach in Richtung des Zurückziehens belastet ist.The cigarette packs 10 transported by the feed conveyor 17 into the pocket 22 located in the loading station 31 run against a pocket stop 35 on the opposite side. In the present exemplary embodiment, this is designed as a two-armed lever with a stop projection 36 that extends from the exit side protrudes into the pocket 22. A pivot bearing 37 is attached to a fixed holding disc 38. A leg 39 of the pocket stop 35 abutting the stop projection 36 is supported by a roller 40 on a cup-shaped cam 41. A (tension) spring 42 acting on the pocket stop 35 has the effect that the roller 40 is constantly in contact with the cam disk 41, and the stop projection 36 is accordingly loaded in the direction of retraction.

Bei Einfördern der Packungs-Gruppe 23 in die Tasche 22 befindet sich der Anschlagvorsprung 36 in der in die Tasche 22 hineinbewegten Stellung (ausgezogene Linie in Fig. 6). Die Pakkungsgruppe 23 läuft gegen den Anschlagvorsprung 36. Bei Weiterbewegung des Trockenrevolvers 18 wird der Anschlagvorsprung 36 zurückgezogen (gestrichelte Stellung). Die Zigaretten-Packungen 10 können nun belastungsfrei in der Tasche 22 mit bewegt werden. Eine abgeschrägte Einlaufkante 43 in einer Revolverseitenwand 44 bewirkt eine Ausrichtung der Packungs- Gruppe 23 in der Tasche 22 durch leichte Verschiebung zur gegenüberliegenden Seite hin (Revolverseitenwand 45).When the pack group 23 is conveyed into the pocket 22, the stop projection 36 is in the position moved into the pocket 22 (solid line in FIG. 6). The pack group 23 runs against the stop projection 36. When the drying turret 18 moves further, the stop projection 36 is withdrawn (dashed position). The cigarette packs 10 can now be moved in the pocket 22 without stress. A beveled inlet edge 43 in a turret side wall 44 effects an alignment of the pack group 23 in the pocket 22 by slight displacement to the opposite side (turret side wall 45).

Die Taschen 22 sind so ausgebildet, dass die in Höhe einer horizontalen Mittelebene zugeführten Zigaretten-Packungen 10 mit den Stirnflächen 21 in Radialrichtung nach aussen bzw. innen gerichtet in den Taschen 22 Aufnahme finden. Die Seitenflächen 11 sind in Umfangsrichtung weisend.The pockets 22 are designed in such a way that the cigarette packs 10, which are fed in at the level of a horizontal central plane, are received in the pockets 22 with the end faces 21 in the radial direction outwards or inwards. The side surfaces 11 point in the circumferential direction.

Um einen störungsfreien Weitertransport der Packungsgruppe 23 in der Tasche 22 zu gewährleisten, werden die nachfolgenden Zigaretten-Packungen im Bereich des Zuförderers 17 momentan angehalten. Im vorliegenden Falle werden die in Bewegungsrichtung vornliegenden (aufgestauten) Zigaretten-Packungen 10 durch Festklemmen angehalten. Zu diesem Zweck ist seitlich neben dem Zuförderer 17 eine Klemmplatte 46 beweglich gelagert. Diese ist an einem langgestreckten Hebelarm 47 angebracht, der durch ein geeignetes Getriebe 48 pulsierend angetrieben wird. In der in Fig. 6 gezeigten Stellung werden mehrere Zigaretten-Packungen mit ihren Stirnflächen 21 gegen eine feststehende Seitenführung 49 neben dem Zuförderer 17 gedrückt. Sobald die nächste Tasche 22 in die Beschikkungsstation 31 bewegt worden ist, wird die Klemmplatte 46 zurückbewegt, so dass die aufgestauten Zigaretten-Packungen 10 in die Tasche 22 gefördert werden können. Die Seitenführung 49 ist bei dem vorliegenden Ausführungsbeispiel mit der Revolverseitenwand 44 verbunden.In order to ensure trouble-free further transport of the pack group 23 in the pocket 22, the following cigarette packs are momentarily stopped in the area of the feed conveyor 17. In the present case, the cigarette packs 10 lying ahead (pent-up) in the direction of movement are stopped by clamping. For this purpose, a clamping plate 46 is movably mounted on the side next to the feed conveyor 17. This is attached to an elongated lever arm 47 which is driven in a pulsating manner by a suitable gear 48. In the position shown in FIG. 6, a plurality of cigarette packs are pressed with their end faces 21 against a fixed side guide 49 next to the feed conveyor 17. As soon as the next pocket 22 has been moved into the loading station 31, the clamping plate 46 is moved back so that the pent-up cigarette packs 10 can be conveyed into the pocket 22. The side guide 49 is connected to the turret side wall 44 in the present exemplary embodiment.

Der Trockenrevolver 18 wird bei der Darstellung in Fig. 4 in Gegenuhrzeigersinn angetrieben. Die Zigaretten-Packungen befinden sich nahezu während einer gesamten Umdrehung des Trokkenrevolvers 18 in dessen Taschen 22. Die Ausschubstation 32 ist unmittelbar unterhalb der Beschickungsstation 31 gebildet. Die Packungs- gruppe 23 wird durch einen Ausstosser 50 aus der betreffenden Tasche 22 herausgefördert über ein gewundenes Zwischenstück 51 bis in einen Abförderer 52. Letzterer besteht ebenfalls aus oberen und unteren Gurten, zwischen denen die in bezug auf Klebungen ausgehärteten Packungen Aufnahme finden. Das Zwischenstück 51 besteht aus schräg- bzw. bogenförmig verlaufenden Führungswänden als Übergang von der Tasche 22 zum in horizontaler Ebene sich erstreckenden Abförderer 52.The drying revolver 18 is driven in the counterclockwise direction in the illustration in FIG. 4. The cigarette packs are located in the pockets 22 of the drying turret 18 for almost an entire revolution. The ejection station 32 is formed immediately below the loading station 31. The pack group 23 is conveyed out of the relevant pocket 22 by an ejector 50, via a tortuous intermediate piece 51, into a discharge conveyor 52. The latter also consists of upper and lower straps, between which the packs hardened with regard to adhesives are accommodated. The intermediate piece 51 consists of inclined or curved guide walls as a transition from the pocket 22 to the removal conveyor 52 extending in the horizontal plane.

Der Aussstosser 50 ist als abgewinkelter Arm ausgebildet mit einem horizontalen Schenkel 53, der bei hin- und hergehender Bewegung des Ausstossers 50 durch die zu entleerende Tasche 22 hindurchbewegt wird bis zum Abförderer 52. Der übrige Teil des Ausstossers 50 ist seitlich neben dem Trockenrevolver 18 verschiebbar gelagert, und zwar auf im wesentlichen horizontalen, achsparallel zum Trockenrevolver 18 gerichteten Tragstangen 54. Der Antrieb des so ausgebildeten Ausstossers 50 erfolgt durch eine Kurbel 55 mit umlaufender Antriebsscheibe 56 und Kurbelstange 57. Letztere ist (schwenkbar) mit einem den Ausstosser 50 tragenden Schlitten 58 verbunden. Dieser ist gleitend auf den Tragstangen 54 gelagert.The ejector 50 is designed as an angled arm with a horizontal leg 53 which, when the ejector 50 moves back and forth, is moved through the pocket 22 to be emptied as far as the discharge conveyor 52. The remaining part of the ejector 50 can be moved laterally next to the drying turret 18 mounted, namely on essentially horizontal, parallel to the drying turret 18 support rods 54. The ejector 50 thus formed is driven by a crank 55 with a rotating drive disk 56 and crank rod 57. The latter is (pivotable) with a slide 58 carrying the ejector 50 connected. This is slidably supported on the support rods 54.

Die äussere Ringwand 33 sowie die Revolverseitenwände 44 und 45 des Trockenrevolvers 18 sind im Bereich der Ausschubstation 32 und im Bereich der Beschickungsstation 31 unterbrochen bzw. mit Ausnehmungen 59 und 60 versehen. Die Ausnehmung 59 im Bereich der Ausschubstation 32 ermöglicht den freien Durchtritt des Ausstossers 50 bzw. des Schenkels 53.The outer ring wall 33 and the turret side walls 44 and 45 of the drying turret 18 are interrupted in the area of the extension station 32 and in the area of the loading station 31 or provided with recesses 59 and 60. The recess 59 in the region of the extension station 32 enables the ejector 50 or the leg 53 to pass freely.

Der weitere Aufbau des Trockenrevolvers 18 in der vorliegenden Ausführungsform ergibt sich vor allem aus Fig. 6 und 7. Die Revolverseitenwände 44 und 45 bilden mit der Ringwand 33 ein geschlossenes Gehäuse.The further structure of the drying turret 18 in the present embodiment results primarily from FIGS. 6 and 7. The turret side walls 44 and 45 form a closed housing with the ring wall 33.

In diesem ist auch der Antrieb für den Trockenrevolver 18 untergebracht. Über ein Zahnradgetriebe 61 wird ein Hauptrad 62 angetrieben, welches auf einer feststehenden mittigen Achse 63 gelagert ist. Mit dem Hauptrad 62 umlaufend und deshalb mit diesem verbunden ist die Tragscheibe 34, an dessen äusseren Umfang die Taschen 22 angebracht sind. An der Tragscheibe 34 ist auch die Kurvenscheibe 41 als seitlich abstehender Kranz angeordnet. Die den Taschen 22 bzw. der beweglichen Seitenwand 25 derselben zugeordnete Kurvenscheibe 29 ist mit der Achse 63 verbunden. Bei dem gezeigten Ausführungsbeispiel ist die Kurvenscheibe 29 mit der Haltescheibe 38 identisch, der äussere Umfang dieser Haltescheibe 38 bildet zugleich die Kurvenscheibe 29. Die Haltescheibe ist mit einer Öffnung 64 versehen, durch die der Schenkel 39 des Taschenanschlags 35 samt Laufrolle 40 hindurchtritt, um Anlage an der Kurvenscheibe 41 zu erhalten.The drive for the drying turret 18 is also accommodated in this. A main gear 62 is driven via a gear transmission 61 and is mounted on a fixed central axis 63. With the main wheel 62 rotating and therefore connected to it, the support disc 34, on the outer circumference of which the pockets 22 are attached. The cam disk 41 is also arranged on the support disk 34 as a laterally protruding ring. The cam plate 29 assigned to the pockets 22 or the movable side wall 25 thereof is connected to the axis 63. In the exemplary embodiment shown, the cam disc 29 is identical to the retaining disc 38, the outer circumference of this retaining disc 38 also forms the cam disc 29. The retaining disc is provided with an opening 64 through which the leg 39 of the pocket stop 35 together with the roller 40 passes, in order to rest to get on the cam 41.

Bei dem vorliegenden Ausführungsbeispiel sind die Kapazitäten der Trockenrevolver 14 und 18 so ausgelegt, dass die Packungen jeweils etwa 15 sec. in jedem Trockenrevolver Aufnahme finden. Die gesamte Trockenzeit von 30 sec. ist ausreichend, um stabile Packungen zu erhalten. Der zweite Trockenrevolver 18 kann - wie der erste Trockenrevolver 14 - in geeigneter Weise beheizt sein.In the present exemplary embodiment, the capacities of the drying turrets 14 and 18 are designed such that the packs are accommodated in each drying turret for about 15 seconds each. The total drying time of 30 seconds is sufficient to obtain stable packs. The second drying turret 18 - like the first drying turret 14 - can be heated in a suitable manner.
