Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Zuschnitten, insbesondere Kragen, aus Verpackungsmaterial, vorzugsweise für Packungen von Zigaretten, wobei eine Materialbahn mindestens einer Prägewalze zugeführt wird, die die Materialbahn bezogen auf eine volle Umdrehung der Prägewalze um 360° während mindestens einer Teilrotationsphase mit Prägungen versieht und die während mindestens einer anderen Teilrotationsphase keine Prägungen in die Materialbahn einbringt, und wobei eine nachfolgende Trennschnittwalze die Materialbahn zur Bildung von einzelnen Zuschnitten mit Trennschnitten versieht. Darüber hinaus betrifft die Erfindung eine entsprechende Vorrichtung zur Durchführung des Verfahrens sowie eine Prägewalze, die in einer solchen Vorrichtung eingesetzt werden kann.The invention relates to a method for the production of blanks, in particular collars, from packaging material, preferably for packs of cigarettes, wherein a material web is fed to at least one embossing roll, the material web based on a full revolution of the embossing roll by 360 ° during at least a partial rotation phase with embossing provides and during at least one other partial rotation phase does not introduce embossments in the material web, and wherein a subsequent separating cutting roller provides the material web to form individual blanks with separating cuts. In addition, the invention relates to a corresponding device for carrying out the method and an embossing roller, which can be used in such a device.

Derartige Verfahren und Vorrichtungen sind in der DE 10 2005 056 627 A1 der Anmelderin offenbart. Darin ist gezeigt, die Umfangsfläche einer Prägewalze zur Prägung von Innenumhüllungen für Zigarettenpackungen mit einer Freimachung auszurüsten. Die auf diese Weise segmentierte Prägewalze ermöglicht es, den entsprechenden Zuschnitt mit einem ungeprägten Bereich zu versehen bzw. nicht den gesamten Zuschnitt prägen zu müssen. Sollten Fehlstellungen zwischen zu prägender Materialbahn und Prägewalze detektiert werden, kann zudem die Relativposition zwischen Prägewalze und Materialbahn angepasst werden. Eine Anpassung der Relativlage zwischen Materialbahn und Prägewalze erfolgt dabei in der DE 10 2005 056 627 A1 dadurch, dass in den Phasen, in denen die Materialbahn aufgrund der vorgenannten Ausnehmung von der Prägewalze nicht geprägt wird, also an der Prägewalze frei läuft, die Materialbahngeschwindigkeit verändert wird Hierzu wird die Geschwindigkeit einer separaten Vorzugswalze verändert. Die Verwendung solcher Vorzugswalzen hat allerdings Nachteile. Unter anderem haben diese Vorzugswalzen einen hohen Platzbedarf, sodass Trennschnittwalze, Prägewalze und Vorzugswalze regelmäßig nicht innerhalb eines gemeinsamen Gehäuses Platz finden.Such methods and devices are in the DE 10 2005 056 627 A1 the applicant discloses. It is shown to provide the peripheral surface of an embossing roll for embossing inner wrappers for cigarette packs with a franking. The embossing roller segmented in this way makes it possible to provide the corresponding blank with an unembossed area or not to have to emboss the entire blank. If misalignments between the material web to be embossed and the embossing roll are detected, the relative position between the embossing roll and the material web can also be adapted. An adaptation of the relative position between the material web and the embossing roller takes place in the DE 10 2005 056 627 A1 The fact that in the phases in which the material web is not embossed by the embossing roll due to the aforementioned recess, that is, the web speed is changed, the web speed is changed For this purpose, the speed of a separate feed roller is changed. However, the use of such feed rollers has disadvantages. Among other things, these feed rollers have a high Required space, so that separating cutting roller, embossing roller and feed roller regularly do not fit within a common housing.

In der DE 10 2009 030 069 A1 wird eine Vorrichtung zum Prägen von insbesondere Kragen einer Klappschachtel für Zigaretten gezeigt, bei der ein Sensor Druckmarken an der Materialbahn abtastet und so die Walzen zum Prägen und Zuschneiden steuert. Auf diese Weise kann eine Prägung positionsgenau angebracht werden.In the DE 10 2009 030 069 A1 a device for embossing particular collar of a folding box for cigarettes is shown in which a sensor scans printed marks on the material web and thus controls the rolls for embossing and cutting. In this way, an embossing can be accurately positioned.

Die US 2009/0050001 A1 offenbart eine Vorrichtung zum Bearbeiten von Verpackungsfolien. Darin sind Prägewalzen zum Prägen von Faltknicken vorgesehen, deren Rotationsgeschwindigkeit verändert werden kann. Beispielsweise werden die Prägewalzen vor dem Prägen abgebremst, so dass das Prägen mit verlangsamter Rotationsgeschwindigkeit erfolgt. Auf diese Weise soll die Qualität der Prägung verbessert werden. Anschließend, das heißt, in einer Phase, in der keine Prägung erfolgt, werden die Prägewalzen beschleunigt, damit die Position der Materialbahn wieder an den folgenden Prozess angepasst wird.The US 2009/0050001 A1 discloses an apparatus for processing packaging films. This embossing rollers are provided for embossing folding creases whose rotational speed can be changed. For example, the embossing rollers are decelerated before embossing, so that the embossing is carried out at a slower rotational speed. In this way, the quality of the embossing is to be improved. Subsequently, that is, in a phase in which no embossing takes place, the embossing rollers are accelerated so that the position of the web is adapted to the following process again.

Aus der US 5,022,950 geht eine Vorrichtung zum Prägen und Schneiden von bedruckten Labels hervor. Dabei werden Fehlstellungen zwischen den Prägewalzen und der Materialbahn ausgeglichen.From the US 5,022,950 goes out a device for embossing and cutting of printed labels. In this case, misalignments between the embossing rollers and the material web are compensated.

Des Weiteren ist aus der WO 02/092295 A1 eine Vorrichtung bekannt, bei der eine Position einer bedruckten und geprägten Materialbahn mit einer Trennschnittwalze synchronisiert wird. Dazu kann die Rotationsgeschwindigkeit der Prägewalzen verändert werden.Furthermore, from the WO 02/092295 A1 a device is known in which a position of a printed and embossed material web is synchronized with a separating cutting roller. For this purpose, the rotational speed of the embossing rollers can be changed.

Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, das eingangs genannte Verfahren und die eingangs genannte Vorrichtung weiterzuentwickeln. Dies insbesondere im Hinblick auf einen möglichst kompakten Herstellprozess mit möglichst wenigen Organen.Proceeding from this, it is an object of the present invention to further develop the aforementioned method and the device mentioned. This particular with regard to a compact manufacturing process with as few organs.

Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1 und einer Vorrichtung mit den Merkmalen des Anspruchs 4.This object is achieved by a method having the features of claim 1 and a device having the features of claim 4.

Erfindungsgemäß ist demnach vorgesehen, die segmentierte Prägewalze mit einer Antriebseinrichtung motorisch anzutreiben, sodass sie Förderkräfte auf die Materialbahn übertragen kann. Die Antriebseinrichtung kann ein ausschließlich der mindestens einen Prägewalze zugeordneter, lokaler Servomotor sein. Theoretisch kann die Antriebseinrichtung aber auch eine zentrale Antriebseinrichtung der Vorrichtung zur Herstellung der Zuschnitte sein, mit der die Prägewalze getrieblich verbunden ist. Wichtig ist, dass die Prägewalze mit anderen Worten die Funktion einer (angetriebenen) Vorzugswalze übernimmt. Regelmäßig werden erfindungsgemäß die vorgenannten Förderkräfte durch das mindestens eine bzw. die vorzugweise mehreren Prägesegment(e) der Prägewalze übertragen. Um gleichzeitig im Bedarfsfall eine Anpassung der Relativlage zwischen Prägewalze und Materialbahn zu ermöglichen, kann die Drehgeschwindigkeit der Prägewalze, die im Normal- bzw. Standardbetrieb, das heißt außerhalb der Anpassphase, zweckmäßigerweise an den Maschinentakt der Herstellvorrichtung gekoppelt ist, übergangsweise verändert bzw. variiert werden. Nämlich in der mindestens einen Teilrotationsphase bzw. in den Teilrotationsphasen, in der/in denen die Prägewalze keine Förderkräfte überträgt. Dies sind regelmäßig die Teilrotationsphasen, in denen die Materialbahn an der Prägewalze frei läuft, in denen also das Freisegment der Materialbahn gegenüberliegt, während die Materialbahn entlang des Freisegments geführt wird.According to the invention, it is accordingly provided to drive the segmented embossing roll by means of a drive device, so that it can transmit conveying forces to the material web. The drive device may be one of only the at least one Embossing roller assigned to be local servo motor. Theoretically, however, the drive device can also be a central drive device of the device for producing the blanks with which the embossing roller is connected in a gear. It is important that the embossing roller in other words takes over the function of a (driven) feed roller. According to the invention, the aforementioned conveying forces are regularly transmitted by the at least one or preferably several embossing segments (e) of the embossing roller. At the same time to allow an adjustment of the relative position between the embossing roller and the material web when needed, the rotational speed of the embossing roller, which is in normal or standard operation, that is outside the fitting phase, expediently coupled to the machine cycle of the manufacturing device, can be transitionally changed or varied , Namely, in the at least one partial rotation phase or in the partial rotation phases in which the embossing roller does not transfer conveying forces. These are regularly the partial rotation phases in which the material web runs free on the embossing roll, ie in which the release segment of the material web is opposite, while the material web is guided along the release segment.

Die Geschwindigkeit der Prägewalze kann innerhalb dieser jeweiligen Teilrotationsphasen beispielsweise kurzzeitig über die vorherige, von dem Maschinentakt abgeleitete Standard-Drehgeschwindigkeit der Prägewalze erhöht oder erniedrigt und spätestens zum Abschluss dieser Teilrotationsphase wieder auf die Standard-Geschwindigkeit abgebremst bzw. beschleunigt werden. Nämlich spätestens bis zu dem Zeitpunkt, zu dem das nächste Prägesegment im Rahmen der weiteren Drehung der Prägewalze mit der Materialbahn in Eingriff gerät und entsprechend wieder Förderkräfte überträgt. Mit anderen Worten werden die Teilrotationsphasen, in denen die Materialbahn an der Prägewalze frei läuft, ausgenutzt, um eine Änderung der Relativlage zwischen Prägewalze und Materialbahn herbeizuführen. Dies natürlich regelmäßig nur dann, wenn eine solche Änderung auch notwendig ist, also bedarfsweise. Wenn demnach mittels geeigneter, im Stand der Technik bekannter Maßnahmen eine Fehlstellung zwischen Materialbahn und Prägewalze detektiert wurde, die dazu führt oder führen würde, dass die Prägungen nicht positionsgerecht auf die Materialbahn aufgebracht werden/würden. Für die Detektion von Fehlstellungen können beispielsweise die Positionen von auf der Materialbahn bezogen auf die Materialbahnlängsrichtung in konstanten Abständen aufgebrachten Markierungen, insbesondere Druckmarken, erfasst und mit ermittelten Ist-Drehlagen der Prägewalze verglichen werden.The speed of the embossing roller can be increased or decreased within these respective partial rotation phases, for example briefly over the previous, derived from the machine cycle standard rotational speed of the embossing roller and braked or accelerated to the standard speed again at the latest at the conclusion of this partial rotation phase. Namely at the latest until the time at which the next embossing segment engages in the course of the further rotation of the embossing roll with the material web and correspondingly transfers conveying forces again. In other words, the partial rotation phases in which the material web runs free on the embossing roller are utilized in order to bring about a change in the relative position between the embossing roller and the material web. This, of course, regularly only if such a change is necessary, so if necessary. Accordingly, if a malposition between the material web and the embossing roll has been detected by means of suitable measures known from the prior art, which would lead or lead to the embossings not being applied to the material web in the correct position. For the detection of misalignments, for example, the positions of the material web on the material web longitudinally applied at constant intervals marks, in particular print marks, detected and compared with determined actual rotational positions of the embossing roll.

Alternativ oder zusätzlich (im Rahmen der Anmeldung, insbesondere den Ansprüchen, wird für die Wendung "alternativ oder zusätzlich" auch "und/oder" im Sinne von "und" oder "oder" benutzt) kann vorgesehen sein, durch übergangsweise Anpassung der Rotationsgeschwindigkeit der Prägewalze auch bedarfsweise die Relativlage zwischen Trennschnittwalze einerseits und Materialbahn andererseits zu verändern. Dies allerdings durch Geschwindigkeitsanpassungen in Teilrotationsphasen, in denen die Prägewalze Förderkräfte auf die Materialbahn überträgt und die Prägewalze als Vorzugswalze die Geschwindigkeit (mit-)bestimmt, mit der die Materialbahn an der Trennschnittwalze entlang geführt wird, sodass entsprechend eine Drehgeschwindigkeitsanpassung der Prägewalze in diesen Phasen auch zu einer Anpassung der Materialbahngeschwindigkeit führt. Wenn die Materialbahn dabei gleichzeitig an der Trennschnittwalze frei bzw. im Wesentlichen frei läuft, kann auf diese Weise die Relativlage zwischen Materialbahn und Trennschnittwalze in gewünschter Weise beeinflusst werden.Alternatively or additionally (in the context of the application, in particular the claims, for the phrase "alternatively or additionally" also "and / or" in the sense of "and" or "or" used) can be provided by transitional adaptation of the rotational speed of Embossing roller also, if necessary, to change the relative position between separating cutting roller on the one hand and material web on the other. This, however, by speed adjustments in partial rotation phases in which the embossing roller transmits conveying forces to the web and the embossing roller as a preferred roller (speed) determines the speed at which the web is guided along the separating cutting roll, so also a rotational speed adjustment of the embossing roll in these phases leads to an adjustment of the material web speed. If the material web at the same time free or substantially free runs on the separating cutting roller, in this way the relative position between the material web and the separating cutting roll can be influenced in the desired manner.

Dabei kann die Geschwindigkeit der Prägewalze - ähnlich wie bei der Anpassung der Relativlage zwischen Prägewalze und Materialbahn - beispielsweise kurzzeitig über die von dem Maschinentakt abgeleitete Standard-Drehgeschwindigkeit der Prägewalze erhöht oder erniedrigt und spätestens zum Abschluss dieser Teilrotationsphase wieder auf die Standard-Geschwindigkeit abgebremst bzw. beschleunigt werden.The speed of the embossing roller - similar to the adjustment of the relative position between embossing roll and material web - for example, increased or decreased briefly over the derived from the machine cycle standard rotational speed of the embossing roll and braked at the latest at the conclusion of this partial rotation phase back to the standard speed or be accelerated.

Indem die Prägewalze in der vorgenannten Weise als angetriebenes Förderorgan eingesetzt wird, kann erfindungsgemäß grundsätzlich auf eine separate Vorzugswalze verzichtet werden. Hierfür ist es allerdings zweckmäßig sicherzustellen, dass in den Teilrotationsphasen, in denen die Materialbahn an der Prägewalze frei läuft, ein anderes angetriebenes Förderorgan die Materialbahnförderung übernimmt.By the embossing roller is used in the aforementioned manner as a driven conveying member, according to the invention can basically be dispensed with a separate feed roller. For this purpose, however, it is expedient to ensure that in the partial rotation phases in which the material web runs free on the embossing roll, another driven conveying element takes over the material web conveying.

Erfindungsgemäß übernimmt dies die vorzugsweise im Maschinentakt mittels einer geeigneten Antriebsteinrichtung angetriebene bzw. in einer daraus abgeleiteten Geschwindigkeit rotierende Trennschnittwalze, die hierfür mit mindestens einem geeigneten Mitnahmesegment, regelmäßig mehreren Mitnehmersegmenten, ausgestattet ist, mit dem bzw. mit denen in den genannten Teilrotationsphasen Förderkräfte auf die Materialbahn übertragen werden. Regelmäßig ist dabei die Antriebseinrichtung gleichzeitig der zentrale Maschinenantrieb, mit dem die Welle der Trennschnittwalze getrieblich verbunden ist. Alternativ kann aber auch ein der Trennschnittwalze zugeordneter Servomotor als separater bzw. lokaler Antrieb eingesetzt werden.According to the invention this assumes the preferably driven in the machine cycle by means of a suitable drive device direction or in a derived speed rotating separating cutting roller, which is equipped with at least one suitable driving segment, regularly several Mitnehmersegmenten, with or with those in the said partial rotation phases conveying forces on the Material web are transmitted. Regularly, the drive device is at the same time the central machine drive, with which the shaft of the separating cutting roller is connected by gearing. Alternatively, however, a servo motor assigned to the separating cutting roller can also be used as a separate or local drive.

Mit anderen Worten sind die Trennschnittwalze einerseits und die Prägewalze andererseits bzw. deren Geschwindigkeiten und Relativdrehlagen im Standardbetrieb, das heißt außerhalb etwaiger Anpassphasen, in denen die Relativposition der Materialbahn in Bezug auf die Prägewalze oder die Trennschnittwalze angepasst wird, so aufeinander abgestimmt bzw. synchronisiert, dass mindestens entweder die eine Walze oder die andere Walze als Vorzugswalze die Materialbahn (weiter-)fördert.In other words, the separating cutting roll on the one hand and the embossing roll on the other hand or their speeds and relative rotational positions in standard operation, that is outside of any adjustment phases in which the relative position of the material web is adjusted with respect to the embossing roller or the separating cutting roller, so matched or synchronized, in that at least either one roller or the other roller advances the material web as an advancing roller.

Die Erfindung wird am Beispiel der Fertigung einer Packung 10 für Zigaretten des Typs Hinge-Lid näher beschrieben. Von dem gesamten Fertigungs- oder Verpackungsprozess für Zigarettenpackungen bzw. Zigaretten wird nur der für die Erfindung wichtige Teil dargestellt. Die nicht beschriebenen Teilprozesse der Herstellung von Zigarettenpackungen können in konventioneller und dem Fachmann bekannter Weise umgesetzt sein.The invention is described in more detail using the example of the production of a package 10 for cigarettes of the hinge-lid type. Of the entire manufacturing or packaging process for cigarette packs or cigarettes only the important part of the invention is shown. The non-described sub-processes of the production of cigarette packs can be implemented in conventional manner known to those skilled in the art.

Die Packung 10 besteht aus den Komponenten Schachtelteil 11, Deckel 12 und Kragen 13". Der Kragen 13" (Fig. 1) ist, wie bei Hinge-Lid-Packungen üblich, im Inneren des Schachtelteils 11 angeordnet und steht aus dem oben offenen Schachtelteil 11 heraus. In Schließstellung des Deckels 12 wird der Kragen 13" von diesem umfasst. Der Kragen 13" erstreckt sich im Bereich von Schachtel-Vorderwand 14 und Schachtel-Seitenwänden 15. Im Bereich der Schachtel-Rückwand 16 ist kein Kragen 13" angeordnet. Der Kragen 13" wird entsprechend durch eine Kragen-Vorderwand 17 und Kragen-Seitenwände 18 gebildet, die sich entlang entsprechender Wandungen des Schachtelteils 11 erstrecken.The package 10 consists of the components box part 11, cover 12 and collar 13 ". Fig. 1 ) is, as usual with hinge-lid packs, arranged inside the box part 11 and stands out of the box part 11 open at the top. The collar 13 "extends in the closed position of the cover 12. The collar 13" extends in the area of the box front wall 14 and the box side walls 15. No collar 13 "is arranged in the area of the box rear wall 16. The collar 13 is correspondingly formed by a collar front wall 17 and collar side walls 18, which extend along corresponding walls of the box part 11.

In an sich bekannter Weise dient das Schachtelteil 11 als Aufnahmeraum für einen Packungsinhalt, nämlich im vorliegenden Fall für einen Zigarettenblock. Bei dem Zigarettenblock handelt es sich um eine Gruppe von Zigaretten, die in eine gemeinsame Umhüllung bzw. einen Innerliner 19 eingehüllt ist. Bei der Packung 10 handelt es sich um eine an sich bekannte Oktogonal-Packung. Die Packung 10 kann natürlich auch andere Grundrissformen aufweisen.In a manner known per se, the box part 11 serves as a receiving space for a package contents, namely in the present case for a cigarette block. The cigarette block is a group of cigarettes wrapped in a common wrapper or innerliner 19. The pack 10 is a known per se octagonal packing. Of course, the package 10 may also have other layouts.

Eine Besonderheit der Packung 10 besteht darin, dass der Kragen 13" Prägungen aufweist.A peculiarity of the pack 10 is that the collar 13 "has embossments.

Bei dem Kragen 13" der Fig. 1 und 3 ist dies zum einen ein Prägemuster 20", das sich vorzugsweise vollflächig, insbesondere nahezu über die volle Kragenbreite, über einen Großteil des oberen, für den Konsumenten sichtbaren Bereich des Kragens 13" erstreckt. Vorliegend oberhalb einer Schließkante 21 des Schachtelteils 11.In the collar 13 "of Fig. 1 and 3 On the one hand, this is an embossing pattern 20 "which preferably extends over the entire surface, in particular almost over the full collar width, over a large part of the upper region of the collar 13" visible to the consumer. In the present case above a closing edge 21 of the box part 11.

Weiterhin ist eine ein gedrucktes, dekoratives Element 22 umgebende Prägung 23 zu erkennen.Furthermore, a stamping 23 surrounding a printed decorative element 22 can be seen.

Die Fig. 2 und 4 zeigen alternative Kragen 13"' bzw. 13' mit alternativen bzw. sich von den jeweils anderen Prägemustern unterscheidenden Prägemustern 20'" und 20'.The Fig. 2 and 4 show alternative collar 13 '' and 13 'with alternative or different from the other embossing patterns embossing patterns 20''and20'.

Bei dem dekorativen Element 22 handelt es sich um eine Bedruckung, die zusammen mit einer Druckmarke 24 auf den jeweiligen Kragen 13'-13"' aufgebracht wird.The decorative element 22 is a print which is applied together with a print mark 24 on the respective collar 13'-13 "'.

Vorzugsweise werden die Bedruckungen, vorliegend das dekorative Element 22 und die Druckmarke 24, außerhalb des Verpackungsprozesses aufgebracht, das heißt, in einem separaten Prozess, innerhalb dessen die Materialbahn 25 hergestellt wird, auf die Materialbahn 25 aufgedruckt. Beispielsweise kann ein Zulieferer des Zigaretten(packungs)herstellers, der die Materialbahn 25 produziert, bereits die Bedruckungen 22, 24 aufbringen. Die Bedruckungen 22, 24 können aber natürlich auch im laufenden Verpackungsprozess erfolgen, in dem die Zigarettenpackungen 10 unter Befüllung mit entsprechenden Zigaretten produziert werden.Preferably, the imprints, in this case the decorative element 22 and the print mark 24, are applied outside the packaging process, that is, printed on the material web 25 in a separate process, within which the material web 25 is produced. For example, a supplier of the cigarette (pack) manufacturer, who produces the material web 25, already apply the imprints 22, 24. Of course, the imprints 22, 24 can also take place during the ongoing packaging process, in which the cigarette packs 10 are produced while being filled with corresponding cigarettes.

Die Materialbahn 25 ist in Längsrichtung in vorgegebenen Abständen mit den Bedruckungen 22, 24 versehen, wobei der Abstand zwischen zwei benachbarten identischen Bedruckungen, also beispielsweise zwei benachbarten dekorativen Elementen 22 und zwei benachbarten Druckmarken 24, der Länge eines einzelnen Zuschnitts 26 entspricht.The material web 25 is provided in the longitudinal direction at predetermined intervals with the imprints 22, 24, wherein the distance between two adjacent identical imprints, so for example two adjacent decorative Elements 22 and two adjacent print marks 24, the length of a single blank 26 corresponds.

Hergestellt werden sämtliche Kragen 13'-13'" mit den jeweiligen Prägungen 20'-20'" bzw. 23 in einem gemeinsamen Herstellungsprozess, indem nach den Prägevorgängen aus ein und derselben fortlaufenden Materialbahn 25 einzelne Zuschnitte 26 herausgetrennt werden. Der Herstellungsprozess ist dabei Teil des übergeordneten Verpackungsprozesses zur Verpackung von Zigaretten. Er findet vorliegend im Bereich einer entsprechenden Verpackungsmaschine statt. Üblicherweise wird der Teil der Verpackungsmaschine, in dem der Kragen hergestellt wird, als Kragenapparat bezeichnet.All collars 13'-13 '"with the respective embossings 20'-20'" and 23 are produced in a common production process by individual blanks 26 being cut out of one and the same continuous material web 25 after the embossing processes. The manufacturing process is part of the overall packaging process for packaging cigarettes. In the present case, it takes place in the area of a corresponding packaging machine. Usually, the part of the packaging machine in which the collar is made, referred to as collar apparatus.

Im Rahmen des Kragenherstellprozesses wird die Materialbahn 25 zunächst mit den Prägungen 20'-20'" bzw. 23 versehen. Alternativ könnte auch wenigstens eine Prägung 20'-20'" bzw. 23 außerhalb des eigentlichen Verpackungsprozesses eingebracht werden, also beispielsweise ebenfalls im Rahmen der Vorfertigung der Materialbahn 25.As part of the collar production process, the material web 25 is first provided with the embossments 20'-20 '"or 23. Alternatively, at least one embossment 20'-20'" or 23 could also be introduced outside the actual packaging process, ie, for example, also within the framework the prefabrication of the material web 25.

Die Prägungen 20'-20'" bzw. 23 werden mittels einer Prägeeinrichtung 27 eingebracht, die ein Prägewalzenpaar 28 umfasst.The embossings 20'-20 '"and 23 are introduced by means of an embossing device 27, which comprises an embossing roller pair 28.

Stromab des Prägewalzenpaares 28 ist eine Schneideinrichtung 29 mit einem Trennschnittwalzenpaar 37 angeordnet, mit der in die Materialbahn 25 unter Bildung einzelner Zuschnitte 26 bzw. einzelner Kragen 13'-13"' Trennschnitte eingebracht werden.Downstream of the embossing roller pair 28, a cutting device 29 is arranged with a separating cut roller pair 37, with which separating cuts are introduced into the material web 25 to form individual blanks 26 or individual collars 13 '- 13 ".

Ein Transportwalzenpaar 30 ist stromab der Schneideinrichtung 29 positioniert und führt die mit Trennschnitten versehene Materialbahn 25 weiter.A transport roller pair 30 is positioned downstream of the cutter 29 and continues to feed the web 25 provided with cuts.

Ein Beschleunigerwalzenpaar 31 zieht schließlich von der mit den Trennschnitten versehenen Materialbahn 25 unter Beschleunigung derselben die einzelnen Zuschnitte 26 bzw. Kragen 13'-13"' ab.Finally, an accelerator roller pair 31 pulls the individual blanks 26 or collars 13 '- 13 "' from the material web 25 provided with the separating cuts while accelerating them.

Die Materialbahn 25 bzw. im Bereich des Beschleunigerwalzenpaares 31 nur noch einzelne Zuschnitte 26 werden dabei entlang einer vorliegend horizontalen Transportbahn 48 jeweils zwischen den aufeinander folgenden Walzenpaaren 28, 37, 30, 31 hindurch gefördert.The material web 25 or in the area of the accelerator roller pair 31 only individual blanks 26 are conveyed along a presently horizontal transport path 48 in each case between the successive pairs of rollers 28, 37, 30, 31.

Im weiteren Verlauf werden die auf diese Weise hergestellten Kragen 13'-13'" im Rahmen des übergeordneten Verpackungsprozesses in der Verpackungsmaschine in an sich bekannter Weise weiterverarbeitet.In the further course, the collars 13'-13 '"produced in this way are further processed in a manner known per se in the context of the superordinate packaging process in the packaging machine.

Eine Besonderheit betrifft die Prägeeinrichtung 27. Sie verfügt über eine auf die Kragen-Vorderwand 17 einwirkende, im vorliegenden Fall obere Prägewalze 27a sowie über eine im vorliegenden Fall untere, betrieblich mit der Prägewalze 27a gekoppelte Gegenwalze 27b. Die Gegenwalze 27b ist gegenüber der Prägewalze 27a auf der entgegengesetzten Kragen-Seite angeordnet, vorliegend der Kragen-Rückwand. Die Prägewalze 27a weist mehrere, vorliegend drei, in Umfangsrichtung voneinander beabstandete bzw. verteilt angeordnete Prägesegmente 32a-32c auf. Die Prägesegmente 32a-32c sind jeweils um ca. 120° versetzt zueinander angeordnet.A special feature concerns the embossing device 27. It has an embossing roller 27a which acts on the collar front wall 17, in the present case an upper embossing roller 27a, and a counter roller 27b, which in the present case is lower and is operatively coupled to the embossing roller 27a. The counter roll 27b is disposed opposite to the embossing roll 27a on the opposite side of the collar, in the present case the collar rear wall. The embossing roll 27a has a plurality of presently three, circumferentially spaced apart or distributed embossed segments 32a-32c. The embossing segments 32a-32c are each offset by approximately 120 °.

Die getrieblich mit der Prägewalze 27a verbundene Gegenwalze 27b weist entsprechende, über den Umfang der Gegenwalze 27b verteilte, voneinander beabstandete Gegensegmente 34a-34c auf. Jeweils ein Gegensegment drückt während der Prägung durch das jeweilige Segment 32a-32c der Prägewalze 27a von unten gegen die Materialbahn 25. Die beiden Walzen 27a, 27b sind so gesteuert bzw. aufeinander abgestimmt, dass die vorgenannten Segmente 32a, 34a; 32b, 34b; 32c, 34c jeweils paarweise mindestens bereichsweise miteinander in Eingriff stehen, sodass die zwischen den beiden Walzen 27a, 27b hindurchgeführte Materialbahn 25 durch die jeweiligen Segmentpaare bereichsweise geprägt wird. Die Segmente 32a-32c bzw. 34a-34c sind dabei im Bereich ihrer jeweiligen Umfangsfläche mit kleinen Erhebungen und Vertiefungen als Prägemittel versehen, die zu den entsprechenden Prägungen 20'-20'" bzw. 23 führen.The counter-roller 27b, which is connected to the embossing roller 27a by means of a gear, has corresponding counterpart segments 34a-34c which are distributed over the circumference of the counter-roller 27b and are spaced apart from each other. In each case a counter segment presses during the embossing by the respective segment 32a-32c of the embossing roller 27a from below against the material web 25. The two rollers 27a, 27b are controlled or coordinated so that the aforementioned segments 32a, 34a; 32b, 34b; 32c, 34c are in pairs at least partially engaged with each other, so that the guided between the two rollers 27a, 27b material web 25 is partially embossed by the respective segment pairs. The segments 32a-32c and 34a-34c are provided in the region of their respective peripheral surface with small elevations and depressions as embossing means, which lead to the corresponding embossings 20'-20 '"and 23, respectively.

Das Prägesegmentpaar 32a; 34a weist Prägemittel auf, die das Prägemuster 20"' einbringen, das Prägesegmentpaar 32b; 34b verfügt über andere Prägemittel, die das Prägemuster 20" einbringen und das Prägesegmentpaar 32c; 34c über nochmals andere Prägemittel für das Prägemuster 20'. Daneben wird von jedem Prägesegmentpaar bzw. von jedem Prägemittel des jeweiligen Prägesegmentpaares jeweils noch die Prägung 23 eingebracht.The embossing segment pair 32a; 34a has embossing means which bring in the embossing pattern 20 "', the embossing segment pair 32b; 34b has other embossing means which introduce the embossing pattern 20" and the embossing segment pair 32c; 34c on yet another embossing means for the embossing pattern 20 '. In addition, each of the embossing segment pair or of each embossing agent of the respective embossing segment pair still introduces the embossment 23.

Mit der Prägeeinrichtung 27 bzw. den auf diese Weise segmentierten Prägewalzen 27a, 27b können demnach im Ergebnis in ein und dieselbe Materialbahn 25 jeweils nacheinander mehrere unterschiedliche Prägungen eingebracht werden, was letztlich die Herstellung der drei unterschiedlichen Kragen 13'-13"' ermöglicht.As a result, a plurality of different embossings can successively be introduced one after the other into the same material web 25 with the embossing device 27 or the embossing rollers 27a, 27b segmented in this way, which ultimately enables the production of the three different collars 13'-13 "'.

In Umfangsrichtung zwischen den einzelnen Prägesegmenten 32a-32c der Prägewalze 27a befinden sich jeweils Freisegmente 33a-33c. Vorliegend sind diese ebenfalls jeweils um 120° zueinander versetzt angeordnet. Bei den Freisegmenten 33a-33c handelt es sich um sich insbesondere über die volle Breite der Umfangsfläche erstreckende Vertiefungen oder Freimachungen in der Umfangsfläche der Prägewalze 27a.In the circumferential direction between the individual embossed segments 32a-32c of the embossing roll 27a, there are respective free segments 33a-33c. In the present case, these are also each offset by 120 ° to each other. The clearance segments 33a-33c are recesses or clearances extending in particular over the full width of the peripheral surface in the peripheral surface of the embossing roller 27a.

Die Relativlage der Bedruckungen 22, 24 einerseits und der Prägungen 20'-20'" bzw. 23 andererseits bzw. der Bedruckungen 22, 24 und dem Prägewalzenpaar 28 wird über einen Druckmarkenleser 35 und einen das Walzenpaar 28 antreibenden Antrieb 36, vorliegend einen Servomotor, mittels einer geeigneten Steuerung so gesteuert, dass die Prägungen 20'-20"' bzw. 23 jeweils an der richtigen Stelle in Bezug auf die Druckmarken 24 bzw. die Bedruckungen 22 positioniert sind. Dies wird später noch näher erläutert.The relative position of the printings 22, 24 on the one hand and the embossments 20'-20 '"or 23 on the other hand or the printings 22, 24 and the embossing roller pair 28 is transmitted via a print mark reader 35 and a drive 36 driving the pair of rollers 28, in this case a servomotor, controlled by suitable control so that the embossments 20'-20 "'and 23 are positioned at the correct position with respect to the print marks 24 and the printings 22, respectively. This will be explained later.

Im vorliegenden Fall dient das Prägewalzenpaar 28 zudem als Förderorgan bzw. als Vorzugswalzenpaar, das jeweils Förderkräfte auf die Materialbahn 25 ausübt, sobald sich eines der Prägesegmente 32a-32c der Prägewalze 27a zusammen mit dem jeweiligen Prägesegment 34a-34c der Prägewalze 27b im Eingriff mit der Materialbahn 25 befindet bzw. die entsprechenden Prägungen einbringt.In the present case, the embossing roller pair 28 also serves as a conveying member or as an advancing roller pair which exerts conveying forces on the material web 25 as soon as one of the embossing segments 32a-32c of the embossing roller 27a engages with the respective embossing segment 34a-34c of the embossing roller 27b Material web 25 is located or brings the corresponding imprints.

Das Prägewalzenpaar 27a, 27b schiebt die Materialbahn 25 dabei stromab entlang des Trennschnittwalzenpaares 37 der Schneideinrichtung 29 in Richtung des Transportwalzenpaares 30. Auf ein separates Förderorgan bzw. eine separate Vorzugswalze kann somit verzichtet werden.The embossing roller pair 27a, 27b thereby pushes the material web 25 downstream along the separating cut roller pair 37 of the cutting device 29 in the direction of the transport roller pair 30. It is thus possible to dispense with a separate conveying element or a separate feed roller.

Der Vorschub der Materialbahn 25 erfolgt naturgemäß nicht, wenn die Materialbahn 25 durch das Prägewalzenpaar 28 hindurch läuft, während sich die Freisegmente 32a-32c entlang der Materialbahn 25 bewegen bzw. wenn keine Prägungen aufgebracht werden.The advance of the material web 25 naturally does not take place when the material web 25 passes through the embossing roller pair 28, while the release segments 32a-32c move along the material web 25 or when no imprints are applied.

Um auch für diesen Fall für einen Weitertransport der Materialbahn 25 zu sorgen, ist die Schneideinrichtung 29 bzw. das Walzenpaar 37 derselben in besonderer Weise ausgebildet. Es umfasst ein obere, auf der Kragenvorderwandseite 17 angeordnete Messerwalze 38a und eine untere, an der Kragenrückwandseite angeordnete Gegenwalze 38b. Die Messerwalze 38a weist über ihre Umfangsfläche verteilt voneinander beabstandete Schneidmittel 39 auf, vorliegend Messer. Die Messer 39 weisen jeweils identische Konturen 40 auf. Dies muss aber nicht so sein. Die Konturen der einzelnen Messer 39 können sich vielmehr auch voneinander unterscheiden.In order to provide for this case for a further transport of the web 25, the cutting device 29 and the roller pair 37 of the same is formed in a special way. It comprises an upper knife roll 38a arranged on the collar front wall side 17 and a lower counter roll 38b arranged on the collar rear wall side. The knife roller 38a has distributed over its peripheral surface spaced apart cutting means 39, in the present case knife. The knives 39 each have identical contours 40. But this does not have to be this way. The contours of the individual blades 39 can rather differ from each other.

Die Messer 39 bringen in die Materialbahn 25 geeignete Trennschnitte ein. Die Kontur 40 des jeweiligen Messers 39 definiert den Verlauf der jeweiligen Oberkante bzw. der jeweiligen Unterkante des späteren Kragens 13'-13"'. Die Trennschnitte werden eingebracht, während die Materialbahn 25 zwischen den beiden Walzen 38a, 38b hindurchbewegt wird.The knives 39 bring in the web 25 suitable separating cuts. The contour 40 of the respective knife 39 defines the course of the respective upper edge or the respective lower edge of the later collar 13'-13 "'. The separating cuts are introduced while the material web 25 is moved through between the two rollers 38a, 38b.

Besonders wichtig ist, dass jedem Messer 39 der Trennschnittwalze 38a ein bezogen auf die Drehrichtung der Messerwalze 38a vorauseilendes Mitnehmersegment 41 zugeordnet ist. Wie in Fig. 12 gezeigt ist, weist das Mitnehmersegment 41 im vorliegenden Fall eine in einem Teilbereich der Umfangsfläche der Messerwalze 38a angeordnete Zackenfläche auf, die die Materialbahn 25 greift, und zwar kurz bevor das jeweilige Messer 39 den entsprechenden Trennschnitt einbringt. Das Mitnehmersegment 41 hinterlässt dabei an der Materialbahn 25 jeweils einen Greifflächenabdruck 43.It is particularly important that each knife 39 of the separating cutting roll 38a is associated with a leading segment 41 leading in relation to the direction of rotation of the knife roll 38a. As in Fig. 12 is shown, the Mitnehmersegment 41 in the present case a arranged in a portion of the peripheral surface of the knife roller 38a serrated surface which engages the web 25, and shortly before the respective blade 39 brings the appropriate separating cut. The driver segment 41 leaves behind on the material web 25 each have a Greifflächenabdruck 43rd

Im Normalbetrieb bzw. im Standardbetrieb des Kragenapparates bzw. der Herstellvorrichtung zur Herstellung von Kragen sind die Drehbewegungen des Prägewalzenpaares 28 und des Trennschnittwalzenpaares 37 so aufeinander abgestimmt, dass das Mitnehmersegment 41 der Messerwalze 38a die Materialbahn 25 zu den Zeiten weiterfördert bzw. ergreift, zu denen das Prägewalzenpaar 28 gerade keine Prägungen in die Materialbahn 25 einbringt bzw. keine Förderkräfte auf die Materialbahn 25 überträgt. Hierdurch ist insgesamt im besten Fall ein kontinuierlicher Vortrieb der Materialbahn 25 gewährleistet.In normal operation or in standard operation of the collar apparatus or the manufacturing device for producing collars, the rotational movements of the embossing roller pair 28 and the separating cut roller pair 37 are coordinated so that the driver segment 41 of the knife roller 38a further advances or grips the material web 25 at the times the embossing roller pair 28 does not introduce any embossments into the material web 25 or transfers any conveying forces to the material web 25. As a result, a continuous propulsion of the material web 25 is ensured overall in the best case.

Sollte die Steuerung der Vorrichtung feststellen, dass die Relativlage der Materialbahn 25 in Bezug auf die Prägewalze 27a bzw. das Prägewalzenpaar 28 eine Fehlstellung aufweist, sodass die Positionen der einzubringenden bzw. bereits eingebrachten Prägungen 20'-20'" bzw. 23 relativ zu den Bedruckungen 22 bzw. 24 fehlerhaft sind oder wären, ändert die Steuerung diese Relativlage.Should the control of the device determine that the relative position of the material web 25 has a misalignment with respect to the embossing roll 27a or the embossing roll pair 28, so that the positions of the embossments 20'-20 '"or 23 introduced relative to the embossing or embossing positions Printings 22 and 24 are or would be incorrect, the controller changes this relative position.

Dies, indem die Geschwindigkeit des Prägewalzenpaares 28 in den Teilrotationsphasen, in denen keine Förderkräfte auf die Materialbahn 25 aufgebracht werden, in denen die Materialbahn 25 also aufgrund der Freisegmente 33a-33c zwischen den Prägewalzen 27a, 27b frei hindurch läuft, jeweils kurzfristig bzw. übergangsweise zur Anpassung der Relativlage verändert wird, nämlich genau während dieser Teilrotationsphasen.This is achieved by the speed of the embossing roller pair 28 in the partial rotation phases in which no conveying forces are applied to the material web 25, in which the material web 25 therefore passes freely between the embossing rollers 27a, 27b due to the release segments 33a-33c, respectively in the short term or transitional manner to adapt the relative position is changed, namely, precisely during these partial rotation phases.

So kann das Prägewalzenpaar 28 in einer oder mehreren dieser Phasen beispielsweise vorübergehend beschleunigt werden, um die Relativlage anzupassen. Spätestens am Ende der Teilrotationsphase wird das Prägewalzenpaar dann wieder auf den ursprünglichen Geschwindigkeitswert abgebremst, nämlich den Wert, der im Standardbetrieb eingestellt ist und der regelmäßig von dem Maschinentakt bzw. der Maschinengeschwindigkeit abgeleitet ist. Alternativ kann das Prägewalzenpaar 28 in diesen Teilrotationsphasen natürlich auch zunächst kurzfristig abgebremst und anschließend wieder auf den Ursprungswert bzw. den Standardwert beschleunigt werden.For example, in one or more of these phases, embossing roller pair 28 may be temporarily accelerated to adjust the relative position. At the latest at the end of the partial rotation phase, the embossing roller pair is then braked back to the original speed value, namely the value that is set in the standard mode and which is derived regularly from the machine cycle or the machine speed. Alternatively, the embossing roller pair 28 can of course also initially be braked for a short time in these partial rotation phases and then accelerated back to the original value or the standard value.

In Fig. 7 ist diejenige Drehlage des Prägewalzenpaares 28 zu erkennen, in der jeweils die Korrektur der Relativlage erfolgen kann. Bezogen auf die Materialbahn 25 kann die Korrektur in dem ungeprägten Bereich 42 (Fig. 8) zwischen zwei eingebrachten Prägemustern erfolgen, in der Fig. 8 beispielsweise den Prägemustern 20" und 20"'.In Fig. 7 is that rotational position of the embossing roller pair 28 to recognize, in each of which the correction of the relative position can take place. With respect to the material web 25, the correction in the unembossed region 42 (FIG. Fig. 8 ) between two embossed patterns, in which Fig. 8 for example, the embossing patterns 20 "and 20"'.

Während der Korrektur der Relativlage des Prägewalzenpaares 28 gegenüber der Materialbahn 25 durch Veränderung der Drehgeschwindigkeit derselben läuft die Materialbahn 25 im Übrigen regelmäßig mit weiterhin konstanter Standardgeschwindigkeit durch die Prägewalzen 27a, 27b hindurch, nämlich vorliegend bedingt durch die Förderkräfte des als Vorzugswalzen eingesetzten Walzenpaares 37 der Schneideinrichtung 29, dessen Drehgeschwindigkeit an den Maschinentakt gekoppelt ist bzw. von diesem abgeleitet ist.During the correction of the relative position of the embossing roller pair 28 relative to the material web 25 by changing the rotational speed thereof, the material web 25 otherwise regularly runs at a still constant standard speed through the embossing rollers 27a, 27b, namely in the present case due to the conveying forces of the roller pair 37 of the cutting device used as advancing rollers 29, whose rotational speed is coupled to the machine cycle or derived from this.

Falls die Steuerung anhand der Lage der Druckmarken 24 und der Drehlage des Walzenpaares 37 erkennt, dass eine Fehlstellung insbesondere der Messerwalze 38a relativ zur Materialbahn 25 vorliegt, dass demnach also die Trennschnitte an falschen Positionen erfolgen oder erfolgen würden, sorgt sie dafür, dass auch diese fehlerhafte Relativlage angepasst bzw. korrigiert wird.If the controller recognizes on the basis of the position of the print marks 24 and the rotational position of the roller pair 37 that there is a misalignment, in particular of the knife roller 38a relative to the material web 25, that accordingly the separating cuts take place or would take place at wrong positions, it ensures that these too incorrect relative position is adjusted or corrected.

Dies in Teilrotationsphasen des Walzenpaares 37, in denen sich die Mitnehmersegmente 41 der Messerwalze 38a nicht im Eingriff mit der Materialbahn 25 befinden und demnach keine Förderkräfte auf die Materialbahn 25 ausüben, vgl. Fig. 5. Bezogen auf die Materialbahn 25 entspricht diese Phase dem Bereich bzw. Abschnitt 56, vgl. Fig. 6. In diesen Phasen, insbesondere in den Rotationsphasen, in denen sich das jeweilige Mitnehmersegment 41 gerade von der Materialbahn 25 gelöst hat, bis zum nächsten Trennschnitt des in Drehrichtung nächst folgenden Messers 39 wird übergangsweise die (Förder-)Geschwindigkeit des Prägewalzenpaares 28 verändert. Nämlich bezogen auf die Drehungen des Prägewalzenpaares in den Phasen, in denen sich das Prägewalzenpaar 28 im prägenden und somit Förderkräfte übertragenden Eingriff mit der Materialbahn 25 befindet. Das Prägewalzenpaar 28 kann dann die Materialbahn 25 in geeigneter Weise beschleunigen oder abbremsen und entsprechend die Relativlage der Materialbahn 25 relativ zu dem Walzenpaar 38 beeinflussen bzw. anpassen.This in partial rotation phases of the roller pair 37, in which the driver segments 41 of the knife roller 38a are not in engagement with the material web 25 and therefore exert no conveying forces on the material web 25, cf. Fig. 5 , With reference to the material web 25, this phase corresponds to the region or section 56, cf. Fig. 6 , In these phases, in particular in the rotational phases in which the respective driver segment 41 has just disengaged from the material web 25 until the next severing cut of the knife 39 next following in the direction of rotation, the (conveying) speed of the embossing roller pair 28 is transitionally changed. Namely, based on the rotations of the embossing roller pair in the phases in which the embossing roller pair 28 is in the embossing and thus conveying forces transmitted engagement with the material web 25. The embossing roller pair 28 can then accelerate or decelerate the material web 25 in a suitable manner and In accordance with the relative position of the material web 25 relative to the pair of rollers 38 influence or adapt.

Wie in Fig. 9 gezeigt ist, verfügt die Messerwalze 37a im Übrigen noch über mehrere in Umfangsrichtung umlaufende, jeweils in axialer Richtung parallel voneinander beabstandete Rilleneindrücker 54, mit denen parallel zu den Materialbahnlängskanten verlaufende, von diesen jeweils beabstandete Rilllinien 55 in die Materialbahn 25 eingedrückt werden können. Entlang dieser Rilllinien 55 kann der Kragen 13'-13'" später in die in Fig. 1 gezeigte Form gefaltet werden.As in Fig. 9 is shown, the knife roller 37a also has a plurality of circumferential circumferential, in each case in the axial direction parallel spaced Rilleneindrücker 54, with which parallel to the web longitudinal edges extending, spaced therefrom each creasing lines 55 can be pressed into the web 25. Along this crease lines 55, the collar 13'-13 '"later in the in Fig. 1 be folded shown shape.

Eine weitere Besonderheit betrifft das Beschleunigerwalzenpaar 31. Es verfügt über eine vorliegend obere, der Kragenvorderwand 17 zugewandte Beschleunigerwalze 50a sowie über eine vorliegend untere, der Kragenrückwand zugewandte Gegenwalze 50b. Die Beschleunigerwalze 50a ist segmentiert. Deren Umfangsfläche verfügt über Freimachungen 51 und 52. Dabei dient die Freimachung 52 der Schonung der auf die jeweiligen Kragen 13'-13'" bzw. der einzelnen Zuschnitte 26 aufgebrachten Prägungen 20'-20'" bzw. 23. Die Beschleunigerwalze 50a ist so gesteuert, dass die Freimachung 52 den Prägungen 20'-20'" bzw. 23 beim Transport der fertigen Kragen 13'-13"' gegenüberliegt, sodass die Beschleunigerwalze 50a den Kragen 13'-13'" in den geprägten Bereichen nicht berührt. Die Freimachung 51 dient dem Eintauchen der jeweiligen Spitze der Kragen 13'-13", wenn sie jeweils in den Bereich der Walzen 50a, 50b übergeben werden. Zum Übertragen von Förderkräften bzw. zum Beschleunigen derselben werden die Kragen 13'-13" dann von einem Mitnehmersegment 53 in ungeprägten Bereichen des Zuschnitts gegriffen.Another special feature relates to the accelerator roller pair 31. It has an upper, the collar front wall 17 facing the accelerator roller 50a and a present lower, the collar rear wall facing counter roller 50b. The accelerator roller 50a is segmented. Their peripheral surface has clearances 51 and 52. In this case, the clearing 52 serves to protect the embossments 20'-20 '"and 23 applied to the respective collars 13'-13'" or the individual blanks 26, respectively. The accelerator roller 50a is thus that the indicia 52 is opposed to the embossments 20'-20 '' 'and 23, respectively, during transport of the finished collars 13'-13' 'so that the accelerator roller 50a does not contact the collar 13'-13' '' in the embossed areas Aiming 51 serves to immerse the respective tip of the collars 13'-13 "when they are respectively transferred to the area of the rollers 50a, 50b. To transmit conveying forces or to accelerate them, the collars 13'-13 "are then gripped by a driver segment 53 in unembossed regions of the blank.

In der Fig. 10 ist eine alternative Ausführungsform der Erfindung gezeigt, bei der die Messerwalze 38a - anders als bei der Ausführungsform gemäß Fig. 9 - keine Rilleneindrücker 54 aufweist. Dies hat den Vorteil, das die Materialbahn 25 für den Fall, dass in der oben beschriebenen Weise eine Anpassung der Relativlage zwischen Messerwalze 37a und Materialbahn 25 notwendig sein sollte, vollständig frei relativ zu der Messerwalze 37a bewegbar ist und diese Bewegung nicht durch den von dem Rilleneindrücker 54 aufgebrachten Druck behindert wird. Um dennoch Rilllinien 55 einbringen zu können, ist für diesen Fall vorgesehen, dass die Beschleunigerwalze 50a entlang ihrer Umfangsfläche entsprechende Rilleneindrücker 54' aufweist, um die Rilllinien 55 zu erzeugen.In the Fig. 10 an alternative embodiment of the invention is shown in which the knife roller 38a - unlike the embodiment according to FIG Fig. 9 - No groove indentor 54 has. This has the advantage that the material web 25 in the event that in the manner described above, an adjustment of the relative position between the knife roller 37 a and web 25 should be necessary, completely free relative to the knife roller 37 a is movable and this movement is not by that of the Rilleneindrücker 54 applied pressure is hindered. In order to still be able to bring in score lines 55, in this case provided that the accelerator roller 50a along their peripheral surface corresponding Rilleneindrücker 54 'to produce the score lines 55.

Zur Erhöhung der Biegesteifigkeit der Materialbahn 25 während des Vorschubtransports der Materialbahn 25 durch das Prägewalzenpaar 28 ist zwischen Prägewalzenpaar 28 und Schneideinrichtung 29 im Übrigen eine Einrichtung 44 zur Krümmung bzw. zum Biegen der Materialbahn 25 angeordnet. Vorliegend wird die Materialbahn 25 symmetrisch zur Längsmittelachse gewölbt, und zwar derart, dass die freien Längskanten derselben nach unten gebogen werden.In order to increase the bending stiffness of the material web 25 during the feed transport of the material web 25 through the embossing roller pair 28, a device 44 for bending or bending the material web 25 is disposed between the embossing roller pair 28 and the cutting device 29. In the present case, the material web 25 is arched symmetrically to the longitudinal central axis, in such a way that the free longitudinal edges thereof are bent downwards.

Die Einrichtung 44 umfasst ein erstes Führungsmittel 45, nämlich vorliegend eine an horizontalen Tragteilen 46 gelagerte Rolle. Die (vorliegend horizontale) Drehachse der Rolle ist quer zur Längserstreckung der Materialbahn 25 angeordnet. Die Rolle 45 ist zentral unterhalb der Längsmittelachse der Materialbahn 25 positioniert und dabei symmetrisch zu dieser ausgerichtet. Sie stützt die Materialbahn 25 von unten bzw. die Materialbahn 25 liegt in einem Mittelbereich auf der Umfangsfläche der Rolle 45 auf.The device 44 comprises a first guide means 45, namely in the present case a mounted on horizontal support members 46 role. The (in this case horizontal) axis of rotation of the roller is arranged transversely to the longitudinal extent of the material web 25. The roller 45 is positioned centrally below the longitudinal central axis of the material web 25 and thereby aligned symmetrically to this. It supports the material web 25 from below or the material web 25 lies in a central region on the peripheral surface of the roller 45.

Im Bereich jeder der freien Längskanten der Materialbahn 25 ist, jeweils etwas nach innen bzw. zur Längsmittelachse versetzt, jeweils auf der oberen Materialbahnseite ein weiteres Führungsmittel 47a, 47b angeordnet, nämlich jeweils eine Rolle 47a bzw. 47b. Die Rollen 47a, 47b sind derart gelagert, dass deren Umfangsflächen zusammen mit der Umfangsfläche der Rolle 45 insgesamt eine symmetrisch zur Längsmittelachse der Materialbahn gekrümmte Transportbahn 49 für die Materialbahn 25 definieren. Dabei drücken die Rollen 47a, b die Materialbahn 25 im Bereich ihrer Längskanten - wie bereits angedeutet - von oben nach unten.
