Weitere Teile der Klappschachtel sind ebenfalls durch Klebung miteinander verbunden. Insbesondere sind Kragen und der Packungsinhalt - ein aus Zigarettengruppe und Innenumhüllung bestehender Zigarettenblock - durch Klebung in der Klappschachtel fixiert. Hierzu wird üblicherweise Kaltleim bzw. Nassleim verwendet. In der US 3,956,865 wird als aftemativer Kleber die Verwendung von Hotmelt-Leim erwähnt.A characteristic feature of this type of pack are double-layer box side walls and lid side walls. Inner and outer box side walls and the lid side walls cover one another in whole or in part and are glued together to form the side walls. Other parts of the Hinged boxes are also connected to each other by gluing. In particular are the collar and the contents of the pack - one made of a cigarette group and inner wrapping existing cigarette block - by gluing in the hinged box fixed. Cold glue or wet glue is usually used for this. In the US 3,956,865 the use of hotmelt glue is mentioned as an adhesive adhesive.

Auch bei der Fertigung von anderen Packungsformen ist der Einsatz von Heißklebern bzw. Hotmelt-Leim bereits bekannt. Diese werden bei Packungen aus Papier auf die Materialbahn zur Bildung von (Papier-)Zuschnitten im Zusammenhang mit der Fertigung von Gebindepackungen aufgebracht. Die Zuschnitte werden sodann von der Bahn abgetrennt, um den Packungsinhalt, also um die Gruppe der Zigarettenpackungen herumgefaltet, wobei Leimstellen durch Wärme reaktiviert werden (EP 0 765 811 A1). Bekannt ist der Einsatz von Heißklebern auch bereits bei Packungen, nämlich Faltschachteln aus Karton. Dabei geht es um die Beleimung von einzelnen Faltlappen, die individuell mit Leim dieses Typs versehen und entsprechend verarbeitet werden (DE 36 12 570 A1; US 3 966 113).The use of hot glue is also used in the manufacture of other pack shapes or hot melt glue already known. These are made out of packs Paper related to the web of material to form (paper) blanks applied with the production of packaging. The cuts will be then separated from the web by the package contents, ie by the group of the cigarette packs folded up, whereby glue spots are reactivated by heat (EP 0 765 811 A1). The use of hot glue is also known already with packs, namely cardboard boxes. It's about the Gluing of individual folding flaps, which are individually provided with glue of this type and processed accordingly (DE 36 12 570 A1; US 3 966 113).

    Klappschachteln bzw. Hinge-Lid-Packungen für Zigaretten oder dergleichen haben einen allgemein üblichen Grundaufbau. Fig. 1 zeigt einen typischen Zuschnitt 10 für die Fertigung einer Klappschachtel. Aus dem einstückigen Zuschnitt 10 aus dünnem Karton oder ähnlichem Verpackungsmaterial wird ein (unterer) Schachtelteil 11 und ein mit diesem verbundener Deckel 12 gefaltet.Hinged lid boxes for cigarettes or The like have a generally common basic structure. Fig. 1 shows a typical blank 10 for the production of a Folding box. From the one-piece blank 10 made of thin Carton or similar packaging material is a (lower) Box part 11 and a lid 12 connected to it folded.

    Zum Schachtelteil 11 gehören eine Schachtel-Vorderwand 13, eine Schachtel-Rückwand 14, eine Bodenwand 15 sowie innenliegende Schachtel-Seitenlappen 16 und außenliegende Schachtel-Seitenlappen 17. Diese bilden zusammen Schachtel-Seitenwände.The box part 11 includes a box front wall 13, one Box rear wall 14, a bottom wall 15 and internal Box side tabs 16 and outside box side tabs 17. Together they form box side walls.

    Analog besteht der Deckel 12 aus Deckel-Vorderwand 18, Deckel-Rückwand 19, Stirnwand 20 sowie inneren Deckel-Seitenlappen 21 und äußeren Deckel-Seitenlappen 22. Letzere bilden zusammen jeweils Deckel-Seitenwände.Similarly, the cover 12 consists of the cover front wall 18 and the cover rear wall 19, end wall 20 and inner cover side tabs 21 and outer lid side tabs 22. The latter together form each Lid side walls.

    Der Deckel 12 ist über eine Gelenklinie 65 im Bereich der Deckel-Rückwand 19 mit der Schachtel-Rückwand 14 schwenkbar verbunden. Am freien Ende der Deckel-Vorderwand 18 ist ein Deckel-Innenlappen 23 angeordnet, der bei der fertigen Klappschachtel gegen die Innenseite der Deckel-Vorderwand 18 gefaltet ist.The lid 12 is on a hinge line 65 in the area of Lid rear wall 19 with the box rear wall 14 pivotable connected. At the free end of the lid front wall 18 is a Lid inner tab 23 arranged in the finished hinged box folded against the inside of the lid front wall 18 is.

    Der Zuschnitt 10 ist an verschiedenen Stellen mit Leim zu versehen, einerseits um Faltlappen miteinander zu verbinden, andererseits um einen aus einem gesonderten Zuschnitt gefertigten Kragen (nicht gezeigt) und den Packungsinhalt, insbesondere einen Zigarettenblock, zu fixieren.The blank 10 is to be provided with glue at various points, on the one hand to connect folding flaps to each other, on the other hand around a made from a separate blank Collar (not shown) and the contents of the pack, in particular to fix a block of cigarettes.

    Die äußeren Schachtel-Seitenlappen 17 sowie die äußeren Deckel-Seitenlappen 22 sind mit Leimstreifen 24 bzw. Leimflächen 25 versehen. Diese Leimbilder dienen zur Verbindung der äußeren Schachtel-Seitenlappen 17 mit den inneren Schachtel-Seitenlappen 16 sowie zur Verbindung der äußeren Deckel-Seitenlappen 22 mit den inneren Deckel-Seitenlappen 21 in entsprechender Faltstellung der Klappschachtel. Diese Verbindung der Seitenlappen 16, 17; 21, 22 erfolgt üblicherweise unmittelbar mit der Fertigstellung der Klappschachtel, wenn die äußeren Seitenlappen 17, 22 aus der Ausgangsstellung bis zur Anlage an die bereits gefalteten inneren Seitenlappen 16, 21 umgefaltet werden.The outer box side tabs 17 and the outer lid side tabs 22 are with glue strips 24 or glue surfaces 25 Mistake. These glue patterns are used to connect the outer Box side tabs 17 with the inner box side tabs 16 and for connecting the outer cover side tabs 22 with the inner lid side tabs 21 in a corresponding folded position the hinged box. This connection of the side lobes 16, 17; 21, 22 usually takes place immediately upon completion the hinged box when the outer side tabs 17, 22 from the starting position to the plant on the already folded inner side tabs 16, 21 are folded over.

    Die Schachtel-Vorderwand 13 ist innenseitig mit (zwei parallelen) Leimstreifen 26 versehen. Diese erstrecken sich bis unmittelbar zum freien Rand der Schachtel-Vorderwand 13. Die Leimstreifen 26 dienen im oberen Bereich - der freien Kante zugeordnet - zum Fixieren eines Kragens. Der untere Teil dient zum Verankern des Packungsinhalts, also des Zigarettenblocks. The inside of the box front wall 13 is provided with (two parallel) Glue strips 26 provided. These extend to immediately to the free edge of the front of the box 13. The strips of glue 26 serve in the upper area - assigned to the free edge - to fix a collar. The lower part is used for Anchoring the contents of the pack, i.e. the cigarette block.

    Auch im Bereich der Schachtel-Rückwand 14 sind innenseitig Leimstreifen 27 angeordnet. Diese haben den Zweck, den Packungsinhalt im Bereich der Rückseite der Klappschachtel zu fixieren.Also in the area of the box rear wall 14 are on the inside Glue strips 27 arranged. These have the purpose of Package contents in the area of the back of the hinged box fix.

    Leimflächen 28 im Bereich der Deckel-Vorderwand 18, nämlich an deren Innenseite, dienen zum Verkleben des Deckel-Innenlappens 23 nach dem Umfalten desselben.Glue surfaces 28 in the area of the lid front wall 18, namely on the inside of them are used to glue the inner flap of the lid 23 after folding it over.

    Mindestens die Beleimung der Seitenlappen 17 und 22, vorzugsweise aber alle Leimbilder, werden auf den ungefalteten Zuschnitt 10 aufgebracht. Zu diesem Zweck wird ein Leim verwendet, der unmittelbar nach dem Aufbringen inaktiv wird und zu einem späteren Zeitpunkt, nämlich entsprechend dem Fertigungsverlauf für die Klappschachtel, wieder aktiviert wird und die Verklebung ermöglicht. Diese Eigenschaft hat Hotmelt-Kleber bekannter Ausführung bzw. Zusammensetzung.At least the gluing of the side tabs 17 and 22, preferably but all glue pictures are on the unfolded blank 10 applied. For this purpose, a glue is used which becomes inactive immediately after application and to a later point in time, namely according to the production process for the hinged box, is reactivated and the gluing enables. This property has hot melt adhesive known execution or composition.

    Bei dem in den Zeichnungen dargestellten, bevorzugten Ausführungsbeispiel werden die Zuschnitte 10 für die Klappschachteln im Bereich einer Verpackungsmaschine ganz oder teilweise gefertigt. Bei dem vorliegenden Ausführungsbeispiel wird der Verpackungsmaschine eine Materialbahn 29 zur Verfügung gestellt, die gemäß Fig. 2 fabrikmäßig teilweise für die Fertigung der Zuschnitte 10 vorbereitet ist.

    Das Verpackungsmaterial, nämlich die Materialbahn 29 (aus dünnem Karton) wird als Bobine 35 mit einer Ersatzbobine 36 zur Verfügung gestellt. Die Materialbahn 29 wird von der aktiven Bobine 35 abgezogen und durch ein Verbindungsaggregat 37 hindurchgeführt. Dieses dient zur Verbindung einer abgelaufenen Materialbahn mit einer neuen.The packaging material, namely the material web 29 (made of thin Carton) is used as a bobbin 35 with a replacement bobbin 36 Provided. The material web 29 is the active Bobine 35 withdrawn and passed through a connecting unit 37. This is used to connect an expired one Material web with a new one.

    Die Materialbahn 29 wird nach dem Verlassen des Verbindungsaggregats 37 umgelenkt und in einem äußersten Seitenbereich der Zuschnittvorrichtung 31 nach oben geführt. Im Bereich einer obere Ecke ist eine Umlenkwalze 38 für die Materialbahn positioniert. Diese lenkt die Materialbahn in eine horizontale Ebene und in den Bereich eines Bahnspeichers 39. Dieser ist als Bahnschleife ausgelegt mit einer Mehrzahl von Umlenkwalzen und einem beweglichen Ausgleichsorgan 40. Dieses weist ebenfalls mehrere Umlenkwalzen für die Materialbahn 29 auf und ist in horizontaler Ebene entlang einer geradlinigen Bewegungsbahn hinund herbewegbar zur Vergrößerung oder Verkleinerung des Bahnspeichers 39. Der Bahnspeicher 39 ist vor allem beim Wechsel der Bobinen 35, 36 aktiv, wenn die Vorrichtung mit reduzierter Geschwindigkeit gefahren wird.The material web 29 is after leaving the connection unit 37 deflected and in an outermost side area of the Cutting device 31 guided upwards. In the area of one a corner roller 38 is positioned for the material web. This directs the material web into a horizontal one Level and in the area of a railway store 39. This is as Web loop designed with a plurality of guide rollers and a movable compensating member 40. This also points several deflecting rollers for the material web 29 and is horizontal Level along a straight line of motion can be moved to enlarge or reduce the web storage 39. The web store 39 is especially when changing of bobbins 35, 36 active when the device is reduced Speed is driven.

    Die Materialbahn 29 wird nach dem Verlassen des Bahnspeichers 39 nach erneuter, abwärts gerichteter Umlenkung einer Zuschnitteinheit 41 zugeführt. Diese besteht aus mehreren in horizontaler Richtung nebeneinander angeordneten Bearbeitungsorganen für die Materialbahn 29 zum Herstellen kompletter Zuschnitte 10. Diese werden nach Verlassen der Zuschnitteinheit 41 einem Verpackungsaggregat zugeführt, insbesondere einem Faltrevolver. Beim vorliegenden Ausführungsbeispiel werden Zuschnittstapel 42 gebildet, die der Verpackungsmaschine bzw. einem Zuschnittmagazin übergeben werden.The material web 29 is after leaving the web store 39 after another, downward deflection of a cutting unit 41 fed. This consists of several in horizontal Direction of processing elements arranged side by side for the material web 29 for producing complete blanks 10. These are left after leaving the cutting unit 41 fed to a packaging unit, in particular one Folding turret. In the present embodiment, blank stacks 42 formed which the packaging machine or be handed over to a blank magazine.

    Bei der Vorbereitung der Materialbahn 29 zur Fertigung der Zuschnitte 10 werden als erstes die Leimbilder auf die Materialbahn 29 aufgebracht. Zu diesem Zweck ist im Bereich eines seitlichen, vertikalen Förderabschnitts der Materialbahn 29 ein Leimaggregat 43 angeordnet. Dieses weist ein Leimorgan 44 auf, welches zum Auftragen der Leimstreifen und Leimflächen 24..28 dient. Das Leimorgan 44 ist mit Leimdüsen 45, 46, 47, 48 versehen. Diese sind an einem Leimkopf 49 gebildet. Die Materialbahn 29 ist so geführt, daß sie zeitweilig oder ständig unter gleitender Anlage an dem Leimkopf 49 vorbeigeführt wird. Die Materialbahn 29 liegt dabei auch an den Leimdüsen 45..48 an. Während einer exakt steuerbaren Öffnungsphase der verschließbaren Leimdüsen 45..48 werden die beschriebenen Leimbilder gemäß Fig. 1 übertragen. Die Öffnungsdauer der Leimdüsen 45..48 bestimmt bei vorgegebener Fördergeschwindigkeit der Materialbahn 29 die Abmessung der Leimstreifen und Flächen in Bewegungsrichtung der Materialbahn. Die Länge der schlitzförmigen Leimdüsen 45..48 bestimmt die Abmessung in Richtung quer zur Förderbewegung.When preparing the material web 29 for the production of the blanks 10 are first the glue pictures on the material web 29 applied. For this purpose, in the area of a side, vertical conveyor section of the material web 29 Glue unit 43 arranged. This has a glue organ 44 which is used to apply the glue strips and glue surfaces 24..28 serves. The glue organ 44 is provided with glue nozzles 45, 46, 47, 48. These are formed on a glue head 49. The web of material 29 is managed so that it is temporarily or constantly under sliding system past the glue head 49. The Material web 29 also lies against the glue nozzles 45..48. During a precisely controllable opening phase of the lockable Glue nozzles 45..48 are the described glue patterns according to Fig. 1 transferred. The opening time of the glue nozzles 45..48 determined at a given conveying speed of the material web 29 the dimensions of the glue strips and surfaces in the direction of movement the material web. The length of the slit-shaped Glue nozzles 45..48 determine the dimension in the direction transverse to Conveying movement.

    Bei dem vorliegenden Ausführungsbeispiel werden die im Format langgestreckten Zuschnitte 10 in Richtung quer zu deren Längserstreckung transportiert aufgrund entsprechend quergerichteter Anordnung innerhalb der Materialbahn 29. In Förderrichtung derselben wird demnach die Breite der Leimstreifen und Leimflächen 24..28 bestimmt. Die Abmessungen in Längsrichtung des Zuschnitts 10 ergeben sich durch die Länge der schlitzförmigen Leimdüsen 45..48. Auch deren Relativstellung am Leimkopf 49 ist auf die Position der Leimbilder im Bereich der Zuschnitte 10 abgestimmt.In the present embodiment, they are in the format elongated blanks 10 in the direction transverse to their longitudinal extent transported due to the corresponding cross direction Arrangement within the material web 29. In the conveying direction of the same accordingly the width of the glue strips and glue areas 24..28 determined. The dimensions in the longitudinal direction of the blank 10 result from the length of the slit-shaped Glue nozzles 45..48. Their relative position on the glue head 49 is also on the position of the glue patterns in the area of the blanks 10 Voted.

    Bei einer Bewegungsrichtung der Zuschnitte 10 quer zu deren Längserstreckung werden nebeneinanderliegende Leimbilder während der Förderbewegung aufeinanderfolgend gebildet. So werden die Leimstreifen 24 und 26 durch dieselbe Leimdüse 45 aufgebracht, und zwar zunächst der in Förderrichtung vornliegende Leimstreifen 24, sodann die beiden Leimstreifen 26 und schließlich der zweite Leimstreifen 24. Diese Leimbilder sind demnach aufgrund der Leimdüse 45 mit gleicher Länge ausgebildet. Unterschiedliche Breiten ergeben sich aus der Öffnungs- bzw. Wirkungsdauer der Leimdüse 45. With a direction of movement of the blanks 10 transversely to their Adjacent glue patterns are used during longitudinal extension of the conveying movement formed successively. So be the glue strips 24 and 26 applied by the same glue nozzle 45, first of all in the conveying direction Glue strips 24, then the two glue strips 26 and finally the second strip of glue 24. These glue patterns are accordingly formed with the same length due to the glue nozzle 45. different Widths result from the opening or duration of action the glue nozzle 45.

    Damit die Materialbahn 29 mindestens während der Beleimung mit einem vorgegebenen Druck am Leimkopf 49 anliegt, sind diesem entsprechend positionierte Andrückwalzen 50, 51 vor- und nachgeordnet. Diese sind im vorliegenden Falle oberhalb und unterhalb des Leimkopfes 49 positioniert. Die Materialbahn 29 wird aufgrund entsprechender Relativstellung der Andrückwalzen 50, 51 im Bereich des Leimkopfes 49 ausgelenkt. Das Leimorgan 44 ist beweglich, nämlich schwenkbar an einem Schwenkarm 52 gelagert. Der Leimkopf 49 kann demnach aus der Leimstellung zurückgezogen werden. Insbesondere wird der Leimkopf 49 von der Materialbahn 29 zurückbewegt, wenn diese stillsteht.So that the material web 29 at least during the gluing a predetermined pressure on the glue head 49 are this appropriately positioned pressure rollers 50, 51 upstream and downstream. In the present case, these are above and below of the glue head 49 positioned. The material web 29 is due to the corresponding relative position of the pressure rollers 50, 51 deflected in the area of the glue head 49. The glue organ 44 is movable, namely pivotably mounted on a pivot arm 52. The glue head 49 can therefore be withdrawn from the glue position become. In particular, the glue head 49 is removed from the material web 29 moved back when it stands still.

    In Förderrichtung der Materialbahn 29 folgt ein Druckmarkensensor 53. Dieser steuert aufgrund von Druckmarken an der Materialbahn 29 die exakte Arbeitsweise des Leimkopfes 49, derart, daß die Leimstreifen und Leimflächen in exakter Relativstellung auf die Materialbahn 29 bzw. auf die Zuschnitte 10 übertragen werden.A print mark sensor follows in the conveying direction of the material web 29 53. This controls on the basis of print marks on the material web 29 the exact mode of operation of the glue head 49, such that the glue strips and glue surfaces in exact relative position on the material web 29 or on the blanks 10 be transmitted.

    Weiterhin wird im Anschluß an das Leimaggregat 43 die korrekte Anordnung und Ausbildung der Leimbilder überprüft durch einen Leimsensor 54. Dieser ist im vorliegenden Falle als gabelförmiges Prüforgan ausgebildet, wobei die Materialbahn zwischen zwei Schenkeln hindurchläuft und dabei durch Sensoren, insbesondere durch kapazitive Sensoren, im Bereich der Leimbilder überprüft wird.Furthermore, the correct after the glue unit 43 Arrangement and formation of the glue patterns checked by a Glue sensor 54. In the present case, this is a fork-shaped one Test organ designed, the material web between two Thighs runs through and through sensors, in particular checked by capacitive sensors in the area of the glue patterns becomes.

    Die beleimte Materialbahn 29 wird sodann an einem Organ zum Aushärten bzw. Deaktivieren des Leims vorbeibewegt. Es handelt sich dabei im vorliegenden Falle um eine Kühlplatte 55, die aufgrund besonderer Ausgestaltung geeignet ist, Wärme und ggf. Feuchtigkeit kurzfristig abzuführen. Die Materialbahn 29 wird unter Anlage bzw. mit geringem Abstand an der Kühlplatte 55 vorbeigeführt.The glued material web 29 is then on an organ for Hardening or deactivating the glue. It deals in the present case is a cooling plate 55 which due to its special design, heat and possibly To remove moisture for a short time. The material web 29 is under contact or at a short distance on the cooling plate 55 past.

    Die hinsichtlich der Beleimung vorbereitete Materialbahn wird in der beschriebenen Weise der Zuschnitteinheit 41 zugeführt. Dieser vorgeordnet ist ein Verformungsaggregat 56, durch das die Materialbahn 29 hindurchläuft. Das Verformungsaggregat 56 ist mit mehreren gegenläufig wirkenden Anlagewalzen für die Materialbahn 29 ausgestattet, die eine Gegenverformung der Materialbahn bewirken gegen die sich aus der Gestalt der Bobinen 35, 36 ergebende gewölbte Verformung.The material web prepared with regard to the gluing is fed to the cutting unit 41 in the manner described. This is preceded by a deformation unit 56 through which the material web 29 runs through. The deformation unit 56 is with several opposing contact rollers for the material web 29 equipped with a counter-deformation of the material web affect against itself from the shape of the bobbin 35, 36 resulting domed deformation.

    Die ebene Materialbahn 29 gelangt nun in die Zuschnitteinheit 41, die je nach Vorgabe in verschiedener Weise ausgebildet sein kann. Im vorliegenden Falle durchläuft die Materialbahn 29 zuerst ein Vorzugaggregat 57 mit Walzen für den exakten Transport der Materialbahn 29. Es folgt danach ein Prägeaggregat 58 zum Anbringen von gestalterischen oder informativen Prägungen an der Materialbahn.The flat material web 29 now arrives in the cutting unit 41, which are designed in different ways depending on the specifications can. In the present case, the material web 29 passes through first a preferred unit 57 with rollers for precise transport the web of material 29. This is followed by an embossing unit 58 for Applying creative or informative imprints the material web.

    Danach tritt die Materialbahn in ein Rillaggregat 59 ein. Dieses bringt durch Rillen vorgeformte Längsfaltlinien 60 und Querfaltlinien 61 im Bereich der Materialbahn 29 durch Prägen an. Ein hieran anschließendes Schneidaggregat 62 dient in der Hauptsache zum Abtrennen der nun fertiggestellten Zuschnitte 10 von der Materialbahn 29. Des weiteren aber werden bestimmte, für den Zuschnitt 10 typische Stanzungen 63, 64 angebracht. Die nach dem Verlassen des Schneidaggregats 62 verarbeitungsfertigen Zuschnitte 10 werden in der beschriebenen Weise abtransportiert zur Bildung von Zuschnittstapeln 42.The material web then enters a creasing unit 59. This brings pre-formed longitudinal fold lines 60 and Cross fold lines 61 in the area of the material web 29 by embossing on. A cutting unit 62 adjoining this serves in the The main thing is to separate the now finished blanks 10 from the material web 29. However, certain for the blank 10 typical punchings 63, 64 attached. The ready for processing after leaving the cutting unit 62 Blanks 10 are removed in the manner described to form blank stacks 42.

    Im Bereich der Verpackungsmaschine werden die Leimstellen nach Ablauf des Verpackungsvorgangs reaktiviert, insbesondere durch Erwärmen. Üblicherweise werden als erstes die Leimflächen 28 reaktiviert, um den Deckel-Innenlappen 23 festzukleben. Danach werden beim Zuführen des Packungsinhalts einschließlich Kragen die Leimstreifen 26 und 27 reaktiviert. Schließlich werden die Leimstreifen 24 und Leimflächen 25 reaktiviert, und zwar üblicherweise im Bereich einer Packungsbahn im Anschluß an einen Faltrevolver.In the area of the packaging machine, the glue spots are removed Reactivation of the packaging process, especially through Heat. Usually, the glue surfaces 28 are first reactivated to glue the lid inner tab 23. After that the contents of the pack including the collar the glue strips 26 and 27 reactivated. Eventually they will Glue strips 24 and glue surfaces 25 reactivated, usually in the area of a packing lane following one Folding turret.

    Das Aufbringen der kompletten Beleimung auf einen Zuschnitt 10 für Klappschachteln kann auch bei der Verarbeitung von anderweitig gefertigten Einzelzuschnitten erfolgen. In diesem Falle wird der Leim auf die bereits fertiggestellten Zuschnitte 10 aufgebracht. Dabei ist es auch möglich, den Transport der Zuschnitte so durchzuführen, daß diese mit Ihrer Längserstreckung in Förderrichtung weisen. Applying the complete gluing to a blank 10 for folding boxes can also be used when processing otherwise manufactured individual cuts. In this case the glue is applied to the already finished blanks 10 applied. It is also possible to transport the blanks to be carried out in such a way that it extends along its length point in the direction of conveyance.

    Besonders vorteilhaft sind Verfahren und Vorrichtung anwendbar bei der Verarbeitung von insbesondere einstückigen Zuschnitten, also mit an einem Hauptzuschnitt angebrachtem Kragen, entsprechend DE 197 26 324.0. The method and device can be used particularly advantageously when processing one-piece blanks in particular, so with a collar attached to a main blank, accordingly DE 197 26 324.0.
