Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Klappschachteln (Hinge-Lid-Packungen), bei denen in einem Schachtelteil ein aus diesem teilweise herausragender Kragen mit Kragenvorderwand und Kragenseitenlappen angeordnet ist, wobei der Kragen als gesonderter Zuschnitt auf die Oberseite eines in einen Inneneinschlag aus Stanniol eingehüllten Zigaretten-Blocks aufgelegt wird, die abstehenden Kragenseitenlappen gegen Seitenflächen des Zigaretten-Blocks gefaltet und dieser sodann mit dem gefalteten Kragen in die Klappschachtel eingeführt wird. Weiterhin betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing hinged boxes (hinge-lid packs), in which a partially protruding collar with a collar front wall and collar side flaps is arranged in a box part, the collar as a separate blank on the top of an inner wrap made of tin foil wrapped cigarette blocks is placed, the protruding collar side tabs folded against side surfaces of the cigarette block and this is then inserted with the folded collar into the hinged box. Furthermore, the invention relates to a device for performing the method.

Klappschachteln sind als Verpackung für Zigaretten weit verbreitet. Klappschachteln bestehen aus einem Schachtelteil und einem an einer Rückwand desselben angelenkten Deckel. Im Schachtelteil ist ein Kragen angeordnet, der üblicherweise als gesonderter Zuschnitt ausgebildet ist und aus Kragenvorderwand und Kragenseitenlappen bzw. -wänden besteht.Hinged boxes are widely used as packaging for cigarettes. Hinged boxes consist of a box part and a lid articulated on a rear wall thereof. A collar is arranged in the box part, which is usually designed as a separate blank and consists of a collar front wall and collar side flaps or walls.

Neuerdings sind Klappschachteln dieser Art bekannt gewor-den, bei denen Längskanten abgerundet, abgeschrägt oder mehreckig ausgebildet sind (US-A-4 753 383 und US-A-4 753 384). Bei diesem Packungstyp müssen auch zwischen Kragenvorderwand einerseits und Kragenseitenwände andererseits gebildete aufrechte Kanten der Form der Längskanten der Packung entsprechen, also abgerundet, abgeschrägt oder mehreckig ausgebildet sein.Hinged boxes of this type have recently become known in which the longitudinal edges are rounded, chamfered or polygonal (US Pat. Nos. 4,753,383 and 4,753,384). In this type of pack, upright edges formed between the front wall of the collar on the one hand and the side walls of the collar on the other must also correspond to the shape of the longitudinal edges of the pack, that is to say they must be rounded, beveled or polygonal.

Aus der nachveröffentlichten EP-A-0 476 804 ist ein Verfahren und eine Vorrichtung zum Auflegen von Kragen auf einen Zigaretten-Block bekannt. Die Kragen werden in vorgeformter Gestalt bzw. Position dem Zigaretten-Block zugeführt.From the post-published EP-A-0 476 804 a method and a device for placing collars on a cigarette block is known. The collars are fed to the cigarette block in a preformed shape or position.

Bei der Erfindung geht es darum, den (gesonderten) Zuschnitt für den Kragen so herzustellen und vorzubereiten, daß das Einbringen des Kragens in die Packung (Klappschachtel) in den gesamten Verpackungsprozeß sinnvoll integriert ist. Die der Erfindung zugrundeliegende Aufgabe besteht darin, Zuschnitte für den Kragen bei Klappschachteln mit abgerundeten, abgeschrägten oder mehreckigen Kanten so herzustellen, vorzubereiten und zuzuführen, daß der Kragen trotz der besonderen Gestaltung der Kanten in herkömmlicher Weise zusammen mit dem Packungsinhalt (Zigaretten-Block) in die Packung eingeführt werden kann.The object of the invention is to produce and prepare the (separate) blank for the collar in such a way that the introduction of the collar into the package (hinged box) is meaningfully integrated into the entire packaging process. The object on which the invention is based is to produce, prepare and supply blanks for the collar in hinged boxes with rounded, beveled or polygonal edges in such a way that the collar in spite of the special design of the edges in a conventional manner together with the contents of the pack (cigarette block) the pack can be inserted.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Verfahren dadurch gekennzeichnet, daß der Kragen durch Verschwenken der Kragenseitenlappen im Bereich der Längskanten unter Bildung von abgerundeten oder mehreckigen Längskanten vorgeformt, in eine annähernd gestreckte, ebene Gestalt zurückgeformt und sodann dem Zigaretten-Block (Packungsinhalt) zugeführt wird.To achieve this object, the method according to the invention is characterized in that the collar is preformed by pivoting the collar side flaps in the region of the longitudinal edges to form rounded or polygonal longitudinal edges, and is then shaped back into an approximately elongated, flat shape and then the cigarette block (package contents) is fed.

Nach den Erkenntnissen der Erfindung können Kragen für Packungen mit in besonderer Weise ausgebildeten Längskanten in herkömmlicher Weise verarbeitet werden, wenn der Kragen eine besondere Vorbehandlung erfährt, nämlich ein Vorformen der Längskanten desselben im Sinne einer Abrundung oder auch mehreckigen Formung und anschließendes Zurückformen in die ebene Gestalt, letztere für den Weitertransport und die Handhabung in der für Kragen üblichen Weise.According to the knowledge of the invention, collars for packs with specially designed longitudinal edges can be processed in a conventional manner if the collar undergoes special pretreatment, namely preforming the longitudinal edges thereof in the sense of rounding or polygonal shaping and then reshaping them into the flat shape , the latter for further transport and handling in the manner customary for collars.

Nach einem weiteren Merkmal der Erfindung wird die Vorformung des Kragens in zwei Schritten vollzogen. Eine Materialbahn zur Herstellung der Kragen durch Abtrennen wird im Bereich der (später herzustellenden) Längskanten vorbehandelt, nämlich durch Prägen auf die spätere, nachfolgende Vorformung ausgerichtet. Diese Prägung besteht bei der Herstellung von Rundkanten aus einer Mehrzahl von parallelen, längsgerichteten Rillen, die durch entsprechende Rillwerkzeuge in die Materialbahn in Längsrichtung derselben im Bereich von zwei Streifen eingebracht werden. Die Rillen werden vorzugsweise von beiden Seiten, also von unten und oben, in die Materialbahn eingeformt. Danach werden die einzelnen Kragen von der Materialbahn abgetrennt und im Bereich einer Formstation vorgeformt durch Umlenken der Kragenseitenlappen relativ zur (horizontal gerichteten) Kragenvorderwand. Danach werden die Kragenseitenwände bzw. -lappen in die horizontale bzw. ebene Gestalt zurückgeführt.According to a further feature of the invention, the collar is preformed in two steps. A material web for the production of the collars by cutting is pretreated in the area of the longitudinal edges (to be produced later), namely aligned by embossing on the subsequent, subsequent preforming. In the production of round edges, this embossing consists of a plurality of parallel, longitudinal grooves, which are made in the longitudinal direction of the material web in the region of two strips by corresponding creasing tools. The grooves are preferably formed into the material web from both sides, that is to say from below and above. Then the individual collars are separated from the material web and preformed in the area of a forming station by deflecting the collar side tabs relative to the (horizontally directed) collar front wall. Then the collar side walls or flaps are returned to the horizontal or flat shape.

Die Vorrichtung zur Vorbehandlung bzw. Herstellung der Kragen besteht aus einer Prägestation zur Vorbehandlung der Materialbahn, aus einer Trennstation zum Herstellen der Kragen und aus einer nachfolgenden Formstation, in der die eigentliche Vorformung der Kragen vollzogen wird. Der Formstation nachgeordnet ist eine Plattform. Durch Aufschieben der Kragen auf die Plattform werden die Kragenseitenwände in eine annähernd gestreckte, ebene Position zurückgeformt. Danach werden die so behandelten Kragen dem Packungsinhalt (Zigaretten-Block) zugeführt.The device for pretreating or producing the collars consists of an embossing station for pretreating the material web, a separating station for producing the collars and a subsequent forming station in which the actual preforming of the collars is carried out. A platform is arranged downstream of the forming station. By pushing the collar onto the platform, the collar side walls are shaped back into an approximately extended, flat position. After that the collars treated in this way are fed into the package contents (cigarette block).

Die Prägestation und die Formstation sind erfindungsgemäß in besonderer Weise ausgebildet bzw. mit besonderen Organen bestückt.According to the invention, the embossing station and the forming station are designed in a special way or are equipped with special organs.

Das in den Zeichnungen dargestellte Ausführungsbeispiel befaßt sich mit der Herstellung von Klappschachteln mit abgerundeten Längskanten, insbesondere in der Ausführung gemäß US-A-4 753 383. Im einzelnen geht es im vorliegenden Falle um die Herstellung und Vorbereitung eines Kragens 10 der geeignet ist für den Einbau in eine derartige Klappschachtel mit abgerundeten Längskanten. Der Kragen 10 besteht aus Kragenvorderwand 11 und Kragenseitenwänden 12. Letztere werden innerhalb der Verpackung bzw. bereits vorher in eine Position quer zur Kragenvorderwand 11 gebracht, wobei Längskanten 13 abgerundet sind.The embodiment shown in the drawings deals with the production of hinged boxes with rounded longitudinal edges, in particular in the embodiment according to US-A-4 753 383. In particular, in the present case it is about the manufacture and preparation of a collar 10 which is suitable for the Installation in such a hinged box with rounded longitudinal edges. The collar 10 consists of the front wall 11 of the collar and the side walls 12 of the collar. The latter are brought into a position transversely to the front wall 11 of the collar within the packaging or already beforehand, the longitudinal edges 13 being rounded.

Die Kragen 10 werden nacheinander von einer Materialbahn 14 aus dünnem Karton abgetrennt, in vorformenden Sinne bearbeitet und sodann durch einen Kragenförderer 15 weiteren Verpackungsaggregaten zugeführt, z.B. einer Einrichtung gemäß US-A-4 612 756.The collars 10 are successively separated from a material web 14 made of thin cardboard, processed in a preforming sense and then fed by a collar conveyor 15 to further packaging units, for example a device according to US Pat. No. 4,612,756.

Die gezeigte Vorrichtung besteht aus einer Prägestation 16, einer in Förderrichtung folgenden Schneidstation 17 und einer Formstation 18.The device shown consists of an embossing station 16, a cutting station 17 following in the conveying direction and a forming station 18.

Die Materialbahn 14 in der Breite der herzustellenden Kragen 10 wird von einer Bobine (nicht gezeigt) abgezogen, und zwar durch Zugwalzen 19, die in Förderrichtung der Prägestation 16 nachgeordnet sind. Die Materialbahn 14 wird demnach von den Zugwalzen 19 kontinuierlich durch die Prägestation 16 hindurchgezogen.The material web 14 in the width of the collar 10 to be produced is drawn off from a bobbin (not shown), specifically by pulling rollers 19 which are arranged downstream of the embossing station 16. The material web 14 is therefore continuously drawn through the embossing station 16 by the pull rollers 19.

Im Bereich der Prägestation 16 wird die Materialbahn 14 fortlaufend mit eng nebeneinanderliegenden Rillen 20 versehen. Die Materialbahn 14 wird dabei im Bereich zweier paralleler Prägestreifen 21 und 22 verformt, derart, daß eine Mehrzahl derartiger Rillen 20 eng nebeneinanderliegt. Die Rillen 20 werden hier von beiden Seiten in das Material eingeformt. Im Bereich der Rillen 20 bzw. der aus diesen bestehenden Prägestreifen 21, 22 werden im Verlaufe des weiteren Fertigungsprozesses die abgerundeten Längskanten 13 gebildet.In the area of the embossing station 16, the material web 14 is continuously provided with closely spaced grooves 20. The material web 14 is deformed in the region of two parallel embossing strips 21 and 22 in such a way that a plurality of such grooves 20 lie closely next to one another. The grooves 20 are molded into the material from both sides here. The rounded longitudinal edges 13 are formed in the area of the grooves 20 or the embossing strips 21, 22 consisting of these in the course of the further manufacturing process.

Die Prägestation 16 ist mit entsprechenden Prägewerkzeugen ausgebildet, nämlich einer unteren Prägewalze 23 und oberen Prägewalzen 24 und 25. Die im vorliegenden Falle unterhalb der Materialbahn 14 angeordnete Prägewalze 23 hat einen im Verhältnis zu den als Gegenwalzen wirkenden Prägewalzen 24 und 25 großen Durchmesser. Die Materialbahn wird innerhalb einer Vertiefung in einer Mantelwandung 27 der Prägewalze 23 geführt. Seitliche Borde 28 begrenzen die Vertiefung 26. Innerhalb derselben sind an der Außenseite der Mantelwandung 27 zwei Rillkränze 29 und 30 angeformt. Diese verlaufen ringsherum, und zwar in einen dem Abstand der Prägestreifen 21, 22 entsprechenden Abstand.The embossing station 16 is designed with corresponding embossing tools, namely a lower embossing roller 23 and upper embossing rollers 24 and 25. In the present case, the embossing roller 23 arranged below the material web 14 has a large diameter in relation to the embossing rollers 24 and 25 acting as counter-rollers. The material web is guided within a recess in a jacket wall 27 of the embossing roller 23. Lateral flanges 28 delimit the depression 26. Within the same, two grooved rings 29 and 30 are formed on the outside of the jacket wall 27. These run all around, in a distance corresponding to the distance between the embossing strips 21, 22.

Die oberen (Gegen-)Prägewalzen 24, 25 sind als einfache zylindrische Rollen ausgebildet und jeweils am Außenumfang ebenfalls mit einem Rillkranz 31, 32 versehen. Diese oberen Rillkränze 31, 32 korrespondieren mit den Rillkränzen 29, 30 der Prägewalze 23, wobei Prägerippen 33 (Fig. 5) versetzt zueinander angeordnet sind, so daß eine rillenbildende Verformung des Materials erfolgen kann.The upper (counter) embossing rollers 24, 25 are designed as simple cylindrical rollers and are also each provided on the outer circumference with a grooved ring 31, 32. These top Creasing rings 31, 32 correspond to the creasing rings 29, 30 of the embossing roller 23, embossing ribs 33 (FIG. 5) being arranged offset from one another, so that a groove-forming deformation of the material can take place.

Die Prägewalzen 23 einerseits und 24, 25 andererseits sind leerlaufend auf feststehenden Achsen 34 bzw. 35 gelagert. Die oberen Prägewalzen 24, 25 sind als Einzelwalzen ausgebildet und auf der Achse 35 mit Spiel zwischen seitliche Führungen (Bund 36) gelagert. Durch das Spiel sind geringe Seitwärtsbewegungen der Prägewalzen 23, 24, 25 möglich. Infolge dieses Bewegungsspielraums können sich die Prägewerkzeuge, nämlich Prägerippen 33 einander gegenüberliegender Rillkränze 29 und 31 bzw. 30 und 32 aufeinander einstellen. Die Prägewalzen 23 einerseits sowie 24 und 25 anderseits sind in einem derartigen Abstand voneinander angeordnet, daß eine die Verformung des Materials des Kragens 10 bewirkende Kraft ausgeübt wird. Zur Erzeugung der parallel laufenden Rillen 20 sind die Prägerippen 33 der zusammenwirkenden Prägewalzen 23, 24, 25 jeweils versetzt zueinander.The embossing rollers 23 on the one hand and 24, 25 on the other hand are mounted idling on fixed axes 34 and 35, respectively. The upper embossing rollers 24, 25 are designed as individual rollers and are mounted on the axis 35 with play between lateral guides (collar 36). The game allows slight sideways movements of the embossing rollers 23, 24, 25. As a result of this freedom of movement, the embossing tools, namely embossing ribs 33 of opposing creasing rings 29 and 31 or 30 and 32, can adjust to one another. The embossing rollers 23 on the one hand and 24 and 25 on the other hand are arranged at such a distance from one another that a force which causes the deformation of the material of the collar 10 is exerted. To create the parallel grooves 20, the embossing ribs 33 of the co-operating embossing rollers 23, 24, 25 are each offset from one another.

Die genaue Gestaltung der Rillkränze 29, 30, 31 ergibt sich aus einer starken Vergrößerung gemäß Fig. 5. Prägerippen sind an der radial außenliegenden Seite mit einer Abflachung 37 gestaltet. Dadurch wird ein messerartiges Einschneiden in den Karton des Kragens vermieden. Die Mitten-Abstände der Prägerippen 33 voneinander beträgt (etwa) 1 mm. Die Breite der Abflachung 37 ist hier auf etwa 0,1 mm bemessen.The exact design of the creasing rings 29, 30, 31 results from a strong enlargement according to FIG. 5. Embossing ribs are designed with a flat 37 on the radially outer side. This avoids knife-like cutting into the carton of the collar. The center distances between the embossing ribs 33 are (approximately) 1 mm. The width of the flat 37 is dimensioned here to be approximately 0.1 mm.

Die Materialbahn 14 wird durch in Förderrichtung auf die Prägestation 16 folgende Zugwalzen 19 zwischen den Prägewalzen 23 einerseits und 24, 25 andererseits hindurchgezogen. In Förderrichtung folgt auf die Zugwalzen 19 die Schneidstation 17, die hier aus zwei einander gegenüberliegenden Schneidwalzen 38, 39 besteht. Auf dem Umfang derselben sind Messer angeordnet, die der Schneidkontur und damit der besonderen Gestaltung der Kragen 10 entsprechen. Beim Transport der Materialbahn 14 zwischen den Schneidwalzen 38, 39 hindurch werden die einzelnen Kragen 10 hergestellt und durch anschließende Förderwalzen 40 mit etwas höherer Geschwindigkeit als die der Materialbahn 14 weitertransportiert. Die Kragen 10 werden dadurch mit einem größer werdenden Abstand voneinander der Formstation 18 zugefördert.The material web 14 is pulled through by pulling rollers 19 following the embossing station 16 between the embossing rollers 23 on the one hand and 24, 25 on the other hand. In the conveying direction, the cutting rollers 17 are followed by the cutting rollers 17, which here consist of two cutting rollers 38, 39 located opposite one another. Knives are arranged on the circumference thereof, which correspond to the cutting contour and so that the special design of the collar 10 correspond. When the material web 14 is transported between the cutting rollers 38, 39, the individual collars 10 are produced and transported further by subsequent conveyor rollers 40 at a somewhat higher speed than that of the material web 14. The collars 10 are thereby fed to the forming station 18 with an increasing distance from one another.

Durch Förderwalzen 41 gelangt der Kragen innerhalb der Formstation 18 auf eine auskragende, lediglich am Ende abgestützte Formplatte 42. Diese ist an die Gestaltung und Abmessung der Kragen 10 angepaßt. Längsseiten der Formplatte 42 sind als Rundkanten 43 ausgebildet. Diese erstrecken sich im Bereich der Prägestreifen 21, 22 und damit im Bereich der herzustellenden Rundkanten. Dies bedeutet, daß die Kragenseitenwände 12 seitlich über die Formplatte 42 hinwegragen.Conveyor rollers 41 bring the collar within the forming station 18 to a cantilevered molding plate 42 which is only supported at the end. This is adapted to the design and dimensions of the collar 10. Long sides of the molding plate 42 are designed as round edges 43. These extend in the area of the embossing strips 21, 22 and thus in the area of the round edges to be produced. This means that the collar side walls 12 protrude laterally over the mold plate 42.

Durch Formwerkzeuge werden die Kragenseitenwände 12 zu beiden Seiten der Formplatte 42 nach abwärts um die Rundkanten 43 geformt, bis unterhalb der Formplatte 42. Hierfür ist ein besonderes Formaggregat 44 vorgesehen, welches zwei quer über die Formplatte 42 bewegbare Formrollen 45 aufweist. Deren Drehachse erstreckt sich in Förderrichtung der Kragen 10.The side walls of the collar 12 are shaped downward on both sides of the molding plate 42 around the round edges 43, to below the molding plate 42. For this purpose, a special molding unit 44 is provided, which has two molding rollers 45 which can be moved transversely over the molding plate 42. Their axis of rotation extends in the conveying direction of the collar 10.

Zur Verformung der Kragenseitenwände 12 in der beschriebenen Weise werden die Formrollen 45 etwa mittig von oben auf den Kragen 10 auf der Formplatte 42 aufgesetzt, sodann in entgegengesetzter Richtung zu den Rändern, nämlich Rundkanten 43 bewegt, an diesen entlanggefahren bis gegen die Unterseite der Formplatte 42. Dabei werden die Kragenseitenwände 12 entsprechend gefaltet unter Bildung einer Abrundung entsprechend der Gestalt der Rundkanten 43 im Bereich der Prägestreifen 21, 22.To deform the collar side walls 12 in the manner described, the shaping rollers 45 are placed approximately centrally from above on the collar 10 on the shaping plate 42, then moved in the opposite direction to the edges, namely round edges 43, along these edges as far as against the underside of the shaping plate 42 The collar side walls 12 are folded accordingly to form a rounding corresponding to the shape of the round edges 43 in the region of the embossing strips 21, 22.

Nach diesem Formvorgang werden die Formrollen 45 in entgegengesetzter Richtung in die Ausgangsposition zurückgefahren, und zwar mit einem Abstand oberhalb der Formplatte 42. Zu diesem Zweck sind die Formrollen 45 jeweils an einem Betätigungsarm 46 des Formaggregats 44 angebracht. Jeder Betätigungsarm 46 ist im Sinne einer Parallelverschiebung bewegbar, und zwar über zwei Kurbeltriebe 47, 48. Diese wiederum werden durch ein hin- und hergehend wirkenden Antrieb 49 innerhalb eines Getriebekastens 50 angetrieben.After this molding process, the molding rollers 45 are moved back in the opposite direction to the starting position, namely at a distance above the molding plate 42. For this purpose, the molding rollers 45 are each attached to an actuating arm 46 of the molding unit 44. Each actuating arm 46 can be moved in the sense of a parallel displacement, specifically by means of two crank drives 47, 48. These in turn are driven by a drive 49 acting to and fro within a gear box 50.

Die in der beschriebenen Weise verformten Kragenseitenwände 12 kehren infolge der Rückstellkräfte des Materials in eine Position unter einem stumpfen Winkel zur Kragenvorderwand 11 zurück. In dieser Stellung wird der Kragen 10 auf eine Abförderplatte 51 geschoben. Für diese taktweise Förderbewegung des Kragens ist ein Förderhebel 52 im wesentlichen unterhalb der Transportebene der Kragen 10 angeordnet. Der Förderhebel 52 erfaßt jeweils einen Kragen 10 auf der Formplatte 42 und schiebt den Kragen durch Schwenkbewegung im Gegenuhrzeigersinn auf die Abförderplatte 51.The collar side walls 12 deformed in the manner described return due to the restoring forces of the material into a position at an obtuse angle to the collar front wall 11. In this position, the collar 10 is pushed onto a discharge plate 51. For this cyclical conveying movement of the collar, a conveying lever 52 is arranged essentially below the transport plane of the collar 10. The conveyor lever 52 each detects a collar 10 on the mold plate 42 and pushes the collar onto the discharge plate 51 by pivoting it counterclockwise.

Der Förderhebel 52 ist in doppelter Ausführung vorhanden, derart, daß je ein Förderhebel 52 zu beiden Seiten der Formplatte 42 bewegbar ist. Die beiden Förderhebel 52 sind darüber hinaus quer zur Förderrichtung bewegbar, nämlich spreizbar. Dadurch ist es möglich, bei der Rückkehrbewegung in die Ausgangsstellung die Förderhebel 52 an einem nachfolgenden Kragen 10 auf der Formplatte 42 seitlich vorbeizuführen in die Ausgangsposition an der Rückseite des Kragens 10.The conveyor lever 52 is provided in duplicate, such that one conveyor lever 52 is movable on both sides of the mold plate 42. The two conveyor levers 52 can also be moved transversely to the conveying direction, namely expandable. This makes it possible, when returning to the starting position, to laterally move the conveying levers 52 past a subsequent collar 10 on the mold plate 42 into the starting position on the rear side of the collar 10.

Auch für den Transport des Kragens 10 in die exakte Position auf der Formplatte 42 ist hier ein Schwenkhebel 54 im wesentlichen unterhalb der Formplatte 42 gelagert. Auch dieser Schwenkhebel 54 ist zweckmäßigerweise doppelt ausgebildet, erstreckt sich demnach mit einem oberen, hakenförmigen Mitnehmerende zu beiden Seiten der Formplatte 42. Der Schwenkhebel 54 ist aus der Ausgangsstellung gemäß Fig. 1 im Bereich der Förderwalzen 41 bis in die Position gemäß Fig. 4 bewegbar, die der exakten Lage des Kragens 10 auf der Formplatte 42 entspricht.Also for the transport of the collar 10 into the exact position on the mold plate 42, a pivot lever 54 is mounted essentially below the mold plate 42. This pivot lever 54 is also expediently double, and accordingly extends with an upper, hook-shaped driver end on both sides of the molding plate 42. The pivot lever 54 is from the starting position according to FIG. 1 in the area of the conveyor rollers 41 can be moved into the position according to FIG. 4, which corresponds to the exact position of the collar 10 on the molding plate 42.

Beim Aufschieben des verformten Kragens 10 auf die Abförderplatte 51 werden die nach unten gerichteten Kragenseiten wände 12 durch Auflaufen auf eine schräge Formfläche 55 am Rand der Abförderplatte 51 in eine annährend horizontale Stellung zurückgeformt.When pushing the deformed collar 10 onto the discharge plate 51, the downward-facing collar sides 12 are formed back into an approximately horizontal position by running onto an oblique shaped surface 55 at the edge of the discharge plate 51.

In dieser annährend horizontalen Ausrichtung, jedoch mit vorgeformten Längskanten 13 wird der Kragen 10 auf der Abförderplatte 51 durch den Kragenförderer 15 quer zur bisherigen Förderrichtung abtransportiert. Der Kragenförderer 15 ist zu diesem Zweck mit einem Förderband, vorzugsweise einem Zahnriehmen 56 ausgerüstet, der an der Außenseite Mitnehmer 57, jeweils zum Erfassen eines Kragens am zugekehrten Rand aufweist. Der Zahnriehmen 56 befindet sich oberhalb der Abförderplatte 51, so daß die Kragen 10 mit dem unteren Trum des Zahnriehmens 56 transportiert werden. Die Abförderplatte 51 ist im Bereich des Zahnriehmens 56 mit einer rinnenartigen Vertiefung 58 versehen.In this approximately horizontal orientation, but with preformed longitudinal edges 13, the collar 10 is transported away on the discharge plate 51 by the collar conveyor 15 transversely to the previous conveying direction. For this purpose, the collar conveyor 15 is equipped with a conveyor belt, preferably a toothed belt 56, which has drivers 57 on the outside, each for gripping a collar on the facing edge. The toothed belt 56 is located above the discharge plate 51, so that the collars 10 are transported with the lower run of the toothed frame 56. The discharge plate 51 is provided in the region of the toothed frame 56 with a groove-like depression 58.

Ein Antrieb 59 für den Zahnriehmen 56 ist seitlich neben dem Kragenförderer 15 angeordnet.A drive 59 for the toothed belt 56 is arranged laterally next to the collar conveyor 15.

Die in der beschriebenen Weise im Bereich der zu bildenden Längskanten 14 bzw. Prägestreifen 21, 22 vorgeformten Kragen 10 können nun in üblicher Weise weiterverarbeitet werden, nämlich insbesondere auf einen Zigaretten-Block (eine in einen Stanniol-Zuschnitt eingehüllte Zigaretten-Gruppe) aufgelegt werden. Die seitlich überstehenden Kragenseitenwände 12 werden im weiteren Verlauf gegen die Seitenflächen des Zigaretten-Blocks umgefaltet und dieser sodann in eine Verpackung (Klappschachtel) eingeschoben, z. B. in der in US-A-4 612 756 beschriebenen Weise.The collars 10 preformed in the manner described in the area of the longitudinal edges 14 or embossing strips 21, 22 can now be processed in the usual way, namely in particular placed on a cigarette block (a cigarette group encased in a tinfoil blank) . The laterally projecting collar side walls 12 are folded over against the side surfaces of the cigarette block in the further course and this is then inserted into a package (hinged box), for. B. in the manner described in US-A-4,612,756.

Bei der Herstellung von Kragen für Packungen mit z.B. achteckigem Querschnitt, also mit abgeschrägten Längskanten gemäß US-A-4,753,384 wird - abweichend von dem beschriebenen Ausführungsbeispiel - so vorgegangen, daß die die Abschrägung bildenden zwei Längskanten nicht durch Prägen bzw. Rillen des Materials markiert sind, sondern durch eine Stanzlinie, ähnlich einer Perforation. Die beiden parallelen Perforationslinien für jede Längskante werden dabei zweckmäßigerweise im Bereich der Schneidstation 17 angebracht. Die Schneidwalze 39 kann längs des Umfangs mit Schneidkanten ausgerüstet sein, die Perforationslinien auf den Kragen 10 übertragen.When producing collars for packs with e.g. octagonal cross-section, i.e. with beveled longitudinal edges according to US-A-4,753,384 - in deviation from the exemplary embodiment described - the procedure is such that the two longitudinal edges forming the bevel are not marked by embossing or creasing the material, but by a punched line, similar to a perforation . The two parallel perforation lines for each longitudinal edge are expediently attached in the region of the cutting station 17. The cutting roller 39 can be equipped with cutting edges along the circumference, which transfer perforation lines to the collar 10.

Danach wird der so vorbereitete Kragen in der oben beschriebenen Weise weiterverarbeitet und behandelt.The collar thus prepared is then processed and treated in the manner described above.
