Abstract

In the manufacture of packages, in particular folding boxes, of rigid packaging material (thin cardboard), individual blanks were hitherto delivered in stacks and introduced successively into the packaging machine. To facilitate the handling of the blanks and to increase the storage capacity, the blanks (23) are now interconnected by means of residual joints (25) to form a continuous web of material (24) wound as a reel (30). Inside the packaging machine, the blanks are successively separated from the web of material (24) by removing the residual joints, preferably by tearing. The residual joints (25) are formed in a region of the blanks (23) or in the region of folding tabs thereof, which are concealed by other folding tabs, that is to say lie on the inside, when the package (folding box) is complete. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Verpackungszuschnitten und zur Zuführung derselben zu einer Verpackungsmaschine, insbesondere für die Ferti­gung von Klappschachteln (Hinge-Lid-Packungen) aus (dün­nem) Karton oder dgl., wobei die Zuschnitte durch Stan­zen von Verpackungsmaterial gebildet werden.The invention relates to a method for producing packaging blanks and for feeding them to a packaging machine, in particular for the production of hinged boxes (hinge-lid packs) from (thin) cardboard or the like, the blanks being formed by punching packaging material.

Bei der Herstellung von Packungen aus dünnem Verpac­kungsmaterial wie Papier wird das Verpackungsmaterial als gewickelte Materialbahn (Bobine) der Verpackungsma schine zur Verfügung gestellt. In der Verpackungsma­schine wird die Materialbahn von der Bobine abgezogen und durch Trennmesser in Zuschnitte aufgeteilt, die dann zur Bildung der Verpackung gefaltet werden.In the production of packages from thin packaging material such as paper, the packaging material is made available to the packaging machine as a wound material web (bobbin). In the packaging machine, the material web is pulled off the bobbin and divided into cuts by cutting knives, which are then folded to form the packaging.

Bei Verpackungsmaterial größerer Steifigkeit, zum Beispiel bei Verpackungen aus Karton, werden Zuschnitte durch Stan­zen aus Materialbögen (Nutzen) fabrikmäßig vorgefertigt, in Stapeln angeliefert und so in die Verpackungsmaschine eingegeben. Diese ist mit einem Zuschnittmagazin für die Aufnahme der gestapelten Zuschnitte und zur Entnahme der­selben nacheinander ausgerüstet. In dieser Weise arbeiten insbesondere Verpackungsmaschinen für die Herstellung von Klappschachteln (Hinge-Lid-Packungen) zur Aufnahme von Zigaretten etc.In the case of packaging material with greater rigidity, for example in the case of packaging made of cardboard, blanks are prefabricated by punching from sheets of material (benefit), delivered in stacks and thus entered into the packaging machine. This is equipped with a blank magazine for taking the stacked blanks and removing them one after the other. This is how packaging machines for the production of hinged boxes (hinge-lid packs) for holding cigarettes etc. work.

Die Vorfertigung der Zuschnitte in gesonderten Ferti­gungsstätten, der Transport und die Handhabung der Zu­schnittstapel ist umständlich und aufwendig. Darüber hin­aus ist aus räumlichen Gründen die Aufnahmekapazität eines Zuschnittmagazins einer Verpackungsmaschine für Zuschnitt­stapel begrenzt.The prefabrication of the blanks in separate production facilities, the transport and handling of the blank stack is cumbersome and time-consuming. In addition, the spatial capacity of a blank magazine of a packaging machine for blank stacks is limited.

Hiervon ausgehend, liegt der Erfindung die Aufgabe zu­grunde, die Herstellung von Zuschnitten und Zuführung derselben zur Verpackungsmaschine bzw. zu Faltaggregaten derselben zu verbessern, insbesondere die Beschickung von Verpackungsmaschinen mit Zuschnitten aus dickerem bzw. festerem Verpackungsmaterial (Karton) zu erleichtern.Proceeding from this, the object of the invention is to improve the production of blanks and the feeding thereof to the packaging machine or to the folding units thereof, in particular to facilitate the loading of packaging machines with blanks from thicker or firmer packaging material (cardboard).

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschla­gen, daß die Zuschnitte von einer fortlaufenden Material­bahn in der Breite mindestens eines Zuschnitts abgetrennt werden, derart, daß zunächst bei der Herstellung der Mate­rialbahn die Zuschnitte bis auf Restverbindungen gestanzt und bei Benutzung, insbesondere innerhalb der Verpackungs­maschine, durch Abreißen von der Materialbahn getrennt werden.To achieve this object, it is proposed according to the invention that the blanks are separated from a continuous web of material in the width of at least one blank, such that the blanks are first punched down to residual connections during manufacture of the web of material and torn off when used, in particular within the packaging machine be separated from the material web.

Der Erfindung liegt die Erkenntnis zugrunde, daß die Her­ stellung kompletter Zuschnitte aus (dünnem) Karton inner­halb der Verpackungsmaschine durch Stanzen nicht durch­führbar ist. Aus diesem Grunde erfolgt eine Vorstanzung der Zuschnitte im Bereich der bisherigen Fertigungsstät­ten, insbesondere in der Kartonagenfabrik. Die Zuschnitte werden aber zusammenhängend über Restverbindungen angelie­fert und so der Verpackungsmaschine zur Verfügung ge­stellt. Im Bereich derselben werden dann die individuellen Zuschnitte durch Abreißen gebildet.The invention is based on the knowledge that the Her provision of complete blanks of (thin) cardboard within the packaging machine by punching is not feasible. For this reason, the blanks are pre-punched in the area of the previous production facilities, especially in the cardboard box factory. However, the blanks are delivered contiguously via residual connections and thus made available to the packaging machine. In the area of the same the individual blanks are then formed by tearing.

Erfindungsgemäß werden die so vorbereiteten Zuschnitte nicht mehr aus blattförmigen Nutzen gefertigt, sondern als fortlaufende, gewickelte, also eine Bobine bildende Mate­rialbahn angeliefert. Diese wird in die Verpackungsmaschi­ne eingesetzt. Die Materialbahn wird abgezogen. Von dieser werden dann nacheinander die Zuschnitte durch Abreißen hergestellt.According to the invention, the blanks prepared in this way are no longer produced from sheet-like panels, but are delivered as a continuous, wound, that is to say forming a bobbin, material web. This is used in the packaging machine. The material web is pulled off. The blanks are then successively produced by tearing them off.

Die innerhalb der Verpackungsmaschine zu beseitigende Restverbindung der Zuschnitte untereinander ist nach einem weiteren wichtigen Merkmal der Erfindung so angeordnet, daß die dabei freiwerdenden Kanten von Faltlappen verdeckt innerhalb der (fertig gefalteten) Packung liegen. Dies be­deutet, daß die durch Abreißen bzw. Abtrennen der Zu­schnitte gebildeten, unregelmäßig gestalteten Kanten an der fertigen Packung nicht sichtbar sind.The remaining connection of the blanks to one another to be eliminated within the packaging machine is arranged according to a further important feature of the invention in such a way that the edges of the folding tabs which are released in the process lie concealed within the (fully folded) package. This means that the irregularly shaped edges formed by tearing or severing the blanks are not visible on the finished package.

Die Zustellung von teilweise vorgefertigten, jedoch noch miteinander verbundenen Zuschnitten aus Karton oder dgl. ermöglicht die Lagerung und Präsentation als gewickelte Rolle (Bobine) größeren Durchmessers von z.B. 80 cm. Da­durch wird im Bereich der Verpackungsmaschine ein be­trächtlicher Vorrat geschaffen, der - je nach Leistungsfä­higkeit der Verpackungsmaschine - für etwa eine Stunde un­unterbrochener Fertigung der Verpackungsmaschine aus­reicht. Die Bobine ist zweckmäßigerweise auf eine Trommel gewickelt, die mit seitlichen Trommelflanschen zum Schutz der vorgestanzten Zuschnitte versehen ist. Der Durchmesser der Trommelflansche ist erfindungsgemäß größer als der Durchmesser der Bobine, so daß die gefüllte Trommel durch Abrollen auf den Trommelflanschen gehandhabt und transpor­tiert werden kann.The delivery of partially prefabricated, but still interconnected blanks of cardboard or the like enables storage and presentation as a wound roll (bobbin) of larger diameter, for example 80 cm. This creates a considerable supply in the area of the packaging machine, which - depending on the performance of the packaging machine - is sufficient for about an hour of uninterrupted production of the packaging machine. The bobbin is conveniently wound on a drum with side drum flanges for protection of the pre-cut blanks. According to the invention, the diameter of the drum flanges is larger than the diameter of the bobbin, so that the filled drum can be handled and transported by rolling on the drum flanges.

Weitere Merkmale der Erfindung beziehen sich auf die Ge­staltung der Zuschnitte, der Materialbahn sowie der Trom­mel zur Aufnahme der Bobine.

Die in den Zeichnungen dargestellten Ausführungsbeispiele betreffen quaderförmige Klappschachteln (Hinge-Lid-Packun­gen) für Zigaretten. Eine derartige Klappschachtel aus dünnem Karton besteht üblicherweise aus einem Schachtel­teil 10 und einem Klappdeckel 11. Der Schachtelteil 10 um­ faßt eine Vorderwand 12, eine gegenüberliegende Rückwand 13, eine diese miteinander verbindende Bodenwand 14 und (schmale) Seitenwände, die aus übereinanderliegenden, also einander überdeckenden äußeren Seitenlappen 15 und ent­sprechenden, etwa gleich breiten inneren Seitenlappen 16 gebildet sind. Die äußeren Seitenlappen 15 sind mit der Vorderwand 12 und die innenliegenden Seitenlappen 16 mit der Rückwand 13 verbunden. Bei der fertig gefalteten Klappschachtel liegen die vorgenannten Seitenlappen 15, 16 unter vollflächiger Überdeckung aneinander und sind mit­einander durch Klebung verbunden.The exemplary embodiments shown in the drawings relate to cuboid hinged boxes (hinge-lid packs) for cigarettes. Such a hinged box made of thin cardboard usually consists of a box part 10 and a hinged lid 11. The box part 10 um includes a front wall 12, an opposite rear wall 13, a bottom wall 14 connecting these to one another and (narrow) side walls which are formed from superimposed, that is to say overlapping, outer side tabs 15 and corresponding, approximately equally wide inner side tabs 16. The outer side tabs 15 are connected to the front wall 12 and the inner side tabs 16 to the rear wall 13. In the case of the folded folding box, the aforementioned side tabs 15, 16 lie against one another with full coverage and are connected to one another by adhesive bonding.

Der Klappdeckel 11, der im vorliegenden Falle ebenfalls nur teilweise gefaltet ist, steht mit dem Schachtelteil 10 bzw. der Rückwand 13 desselben über ein quergerichtetes Klappscharnier 17 in Verbindung. Hieran schließt eine Deckelrückwand 18, eine Deckeloberwand 19 und eine Deckel­vorderwand 20 an.The hinged lid 11, which is also only partially folded in the present case, is connected to the box part 10 or the rear wall 13 thereof via a transverse hinged hinge 17. This is followed by a lid rear wall 18, a lid upper wall 19 and a lid front wall 20.

Auch bei dem Klappdeckel 11 werden Seitenwände aus über­einanderliegenden und miteinander verklebten Deckelseiten­lappen gebildet, und zwar aus mit der Deckelvorderwand 20 verbundenen äußeren Deckelseitenlappen 21 und mit der Dek­kelrückwand 18 verbundenen inneren Deckelseitenlappen 22.In the case of the hinged cover 11, side walls are also formed from cover side tabs lying one above the other and bonded to one another, specifically from outer cover side tabs 21 connected to the front cover wall 20 and inner cover side tabs 22 connected to the rear cover wall 18.

Die so ausgebildete Verpackung (Klappschachtel) wird aus einem Zuschnitt 23 hergestellt, der vorgeprägte Faltlinien zur Begrenzung der beschriebenen Packungswände und Falt­lappen aufweist.The packaging (hinged box) formed in this way is produced from a blank 23 which has pre-embossed folding lines for delimiting the described packaging walls and folding flaps.

Bei dem vorliegenden Ausführungsbeispiel sind die Zu­schnitte 23 zu einer fortlaufenden Materialbahn 24 des Verpackungsmaterials miteinander verbunden. Die Material­bahn 24 (Fig. 2) besteht aus mit ihrer Längserstreckung quergerichteten Zuschnitten 23, die vorgestanzt und vorge­prägt sind. Die nebeneinanderliegenden Zuschnitte 23 sind nur in Teilbereichen der aneinander stoßenden Ränder mit­ einander verbunden, und zwar über Restverbindungen 25, die durch kurze Stanzungen 26 mit Abstand voneinander entste­hen. Außerhalb des Bereichs dieser Restverbindungen 25 sind die Zuschnitte 23 aufgrund durchgehender Stanzschnit­te 27 bzw. 28 voneinander getrennt. Durch die Restverbin­dungen 25 werden die Zuschnitte 23 zu einer fortlaufenden Materialbahn 24 zusammengehalten, deren Breite der Länge der Zuschnitte 23 entspricht. Die Randkonturen der Mate­rialbahn 24 entsprechen der Gestaltung der Zuschnitte in den Endbereichen.In the present exemplary embodiment, the blanks 23 are connected to one another to form a continuous material web 24 of the packaging material. The material web 24 (FIG. 2) consists of blanks 23 which are transverse with their longitudinal extension and which are pre-punched and pre-embossed. The adjacent blanks 23 are only included in partial areas of the abutting edges connected to each other, via residual connections 25, which are formed by short punchings 26 at a distance from one another. Outside the area of these residual connections 25, the blanks 23 are separated from one another due to continuous punch cuts 27 and 28, respectively. The blanks 23 are held together by the remaining connections 25 to form a continuous material web 24, the width of which corresponds to the length of the blanks 23. The edge contours of the material web 24 correspond to the design of the blanks in the end areas.

Die Restverbindungen 25 sind im Bereich von Zuschnitteilen gebildet, die bei der fertigen Klappschachtel innen bzw. verdeckt liegen. Bei dem gezeigten Ausführungsbeispiel sind die benachbarten Zuschnitte 23 im Bereich der innen­liegenden Seitenlappen 16 sowie der ebenfalls innenliegen­den Deckelseitenlappen 22 miteinander verbunden, also in einem mittleren Bereich der Materialbahn 24.The remaining connections 25 are formed in the area of blank parts which are inside or hidden in the finished folding box. In the exemplary embodiment shown, the adjacent blanks 23 are connected to one another in the region of the inner side flaps 16 and also the inner side flaps 22, that is to say in a central region of the material web 24.

Für die Verarbeitung der Zuschnitte 23 werden diese nach­einander von der Materialbahn 24 abgetrennt, nämlich abge­rissen. Die dadurch entstehenden freie Ränder 29 der Sei­tenlappen 16 und Deckelseitenlappen 22 haben eine unregel­mäßige, zackenförmige Gestalt (Fig. 1). Wie geschildert, sind diese Ränder 29 durch die äußeren Seitenlappen 15 bzw. Deckelseitenlappen 21 bei der fertigen Verpackung überdeckt und nach außen nicht sichtbar.For the processing of the blanks 23, these are separated from the material web 24 one after the other, namely torn off. The resulting free edges 29 of the side tabs 16 and lid side tabs 22 have an irregular, jagged shape (FIG. 1). As described, these edges 29 are covered by the outer side tabs 15 or lid side tabs 21 in the finished packaging and are not visible from the outside.

Die gemäß Fig. 2 ausgebildete Materialbahn 24 wird vor­zugsweise zu einer Rolle bzw. Bobine 30 gewickelt. In die­ser raumsparenden Anordnung ist die Materialbahn 24 gün­stig zu transportieren, zu lagern und in der Verpackungs­maschine zu handhaben. Die Bobine 30 ist auf einer Trommel 31 angeordnet, die gemäß Ausführungsbeispiel der Fig. 3 aus einem Trommelkern 32 und seitlichen Trommelflanschen 33 und 34 besteht. Letztere schützen die durch Stanzungen unregelmäßigen Ränder der Materialbahn 24 bzw. Bobine 30.The material web 24 designed according to FIG. 2 is preferably wound into a roll or bobbin 30. In this space-saving arrangement, the material web 24 is inexpensive to transport, store and handle in the packaging machine. The bobbin 30 is arranged on a drum 31 which, according to the exemplary embodiment in FIG. 3, consists of a drum core 32 and lateral drum flanges 33 and 34. The latter protect the irregular edges of the material web 24 or bobbin 30 by punching.

Die Trommelflansche 33, 34 sind so bemessen, daß sie um einen ausreichenden Abstand 35 über den Außenumfang der Bobine 30 hinwegragen. Dadurch kann die gefüllte Trommel 31 durch Rollen auf dem Untergrund transportiert und auf den Trommelflanschen 33, 34 stehend gelagert werden.The drum flanges 33, 34 are dimensioned such that they protrude a sufficient distance 35 over the outer circumference of the bobbin 30. As a result, the filled drum 31 can be transported by rollers on the ground and stored standing on the drum flanges 33, 34.

Der Trommelkern 32 ist in Axialrichtung so bemessen, daß die bei dem vorliegenden Beispiel außermittig gewickelte Bobine 30 auf der durch die Gestaltung der Zuschnitte 23 gegen mechanische Belastungen empfindlichen Seite, nämlich an den freien Rändern der Vorderwand 12 und der spitz aus­laufenden äußeren Seitenlappen 15, einen wirksamen Spalt 36 gegenüber dem benachbarten Trommelflansch 34 bildet. Dieser Spalt 36 verhindert mechanische Belastungen und damit Verformungen der Zuschnitte 23 durch Andrücken an den Trommelflansch 34.The drum core 32 is dimensioned in the axial direction so that the bobbin 30 wound off-center in the present example on the side sensitive to mechanical loads due to the design of the blanks 23, namely on the free edges of the front wall 12 and the tapered outer side tabs 15 effective gap 36 forms against the adjacent drum flange 34. This gap 36 prevents mechanical loads and thus deformations of the blanks 23 by pressing against the drum flange 34.

Zur besseren Handhabung und auch für eine störungsfreie Herstellung der Bobine 30 ist wenigstens ein Trommel­flansch 34 abnehmbar, also der der Vorderwand 12 zugekehr­te. Der Trommelflansch 34 ist zu diesem Zweck mit einer innenseitig angeordneten Steckhülse 37 versehen, die in eine entsprechend bemessene Ringausnehmung 38 des Trommel­kerns 32 formschlüssig aber lösbar eintritt. Der Trommel­kern 32 ist bei diesem Ausführungsbeispiel lediglich mit dem gegenüberliegenden Trommelflansch 33 verbunden.For better handling and also for trouble-free manufacture of the bobbin 30, at least one drum flange 34 can be removed, that is to say the one facing the front wall 12. For this purpose, the drum flange 34 is provided with an internally arranged plug-in sleeve 37 which enters into a correspondingly dimensioned ring recess 38 in the drum core 32 in a form-fitting but releasable manner. In this exemplary embodiment, the drum core 32 is only connected to the opposite drum flange 33.

Eine mittige, durchgehende Trommelöffnung 39 ermöglicht das Aufsetzen auf einen drehbaren Tragzapfen 40 in der Verpackungsmaschine.A central, continuous drum opening 39 enables placement on a rotatable support pin 40 in the packaging machine.

Die Zuschnitte 23 des vorliegenden Ausführungsbeispiels werden in einer Verpackungsmaschine für die Herstellung von Klappschachteln verarbeitet. In Fig. 4 und 5 sind im vorliegenden Zusammenhang interessierende Einzelheiten ei­ner derartigen (im Prinzip bekannten) Verpackungsmaschine gezeigt.The blanks 23 of the present exemplary embodiment are processed in a packaging machine for the production of hinged boxes. 4 and 5 show interesting details of such a packaging machine (known in principle) in the present context.

An der Rückseite eines Maschinengestells 41 ist der nach rückwärts weisende Tragzapfen 40 gelagert, und zwar mit einem solchen Abstand vom Boden, daß eine Bobine 30 bzw. eine Trommel 31 mit geringem Abstand oberhalb des Bodens gehalten wird. Der Tragzapfen 40 ist drehbar angetrieben, und zwar durch einen Motor über ein Ritzel 42 und ein Zahnrad 43.On the back of a machine frame 41, the rearward-facing support pin 40 is mounted at such a distance from the floor that a bobbin 30 or a drum 31 is held a short distance above the floor. The trunnion 40 is rotatably driven by a motor via a pinion 42 and a gear 43.

Die Materialbahn 24 wird durch ein erstes Paar von Zugwal­zen 44, 45 von der Bobine 30 bzw. Trommel 31 abgezogen. Die untere Zugwalze 45 mit größerem Durchmesser hat zu­gleich eine Umlenkfunktion. Mit Abstand über den Zugwalzen 44, 45 ist ein zweites Paar von Zugwalzen 46, 47 abge­ordnet, wobei wiederum die Zugwalze 47 mit größerem Durch­messer als Umlenkwalze wirkt zur Einförderung der Mate­rialbahn 24 in eine horizontale Förderbahn 48. Zwischen den Zugwalzen 44, 45 einerseits und den Zugwalzen 46, 47 andererseits ist ein freier Durchhang 49 der Materialbahn 24 als kleiner Bahnvorrat gebildet. Der Durchhang 49 wird hinsichlich der Größe durch eine Lichtschranke 50 über­wacht.The material web 24 is pulled off the bobbin 30 or drum 31 by a first pair of pull rollers 44, 45. The lower pulling roller 45 with a larger diameter also has a deflecting function. A second pair of pulling rollers 46, 47 is arranged at a distance above the pulling rollers 44, 45, the pulling roller 47 with a larger diameter again acting as a deflecting roller for feeding the material web 24 into a horizontal conveying path 48. Between the pulling rollers 44, 45 on the one hand and the Pull rollers 46, 47, on the other hand, a free sag 49 of the material web 24 is formed as a small web supply. The sag 49 is monitored in terms of size by a light barrier 50.

Im Bereich der horizontalen Förderbahn 48 erfolgt die Trennung der Zuschnitte 23 von der Materialbahn 24, und zwar durch Reißen. Zu diesem Zweck sind zwei Paare von Reißwalzen 51, 52 einerseits und 53 bzw. 54 andererseits mit Abstand in Förderrichtung voneinander angeordnet. Der Abstand der Reißwalzen 51, 52 einerseits von den Reißwal­zen 53, 54 andererseits ist etwas geringer als die Breite eines Zuschnitts 23. Die Reißwalzen 53, 54 werden mit grö­ßerer Geschwindigkeit angetrieben als die Reißwalzen 51, 52. Dadurch wird der jeweils vordere Zuschnitt 23 der Ma­terialbahn 24 von dieser abgerissen.In the area of the horizontal conveyor track 48, the blanks 23 are separated from the material track 24 by tearing. For this purpose, two pairs of tear rollers 51, 52 on the one hand and 53 and 54 on the other hand are arranged at a distance from one another in the conveying direction. The distance of the tearing rollers 51, 52 on the one hand from the tearing rollers 53, 54 on the other hand is slightly less than the width of a blank 23. The tearing rollers 53, 54 are driven at a higher speed than the tearing rollers 51, 52. As a result, the respective front blank 23 becomes Material web 24 torn from this.

Die abgetrennten Zuschnitte 23 werden beim vorliegenden Beispiel in einen aufrechten Zuschnittschacht 55 eingeför­dert, und zwar durch Förderwalzen 56. Dem Zuschnittschacht 55 werden nacheinander Zuschnittstapel 57 entnommen und durch einen Schieber 58 auf einen Querförderer 59 gegeben. Dieser transportiert aufeinanderfolgende Zuschnittstapel 57 in einen Bereich oberhalb eines in üblicher Weise aus­gebildeten Zuschnittmagazins 60. Der jeweils ankommende Zuschnittstapel 57 wird durch eine Absenkplattform 61 in den oberen Bereich des Zuschnittmagazins 60 durch Abwärts­bewegung eingeführt. Die Absenkplattform 61 wird in der unteren Stellung in Querrichtung zurückgezogen (strich­punktierte Stellungen) und dann in die obere Aufnahmestel­lung für den nächsten Zuschnittstapel 57 zurückbewegt, und zwar durch entsprechend angetriebene Lenker 62.In the present example, the cut blanks 23 are fed into an upright blanking chute 55, specifically by conveyor rollers 56. The blanking chute 55, stack of blanks 57 are removed one after the other and placed on a cross conveyor 59 by a slide 58. This transports successive blank stacks 57 into an area above a custom-designed blank magazine 60. The respectively arriving blank stack 57 is introduced through a lowering platform 61 into the upper area of the blank magazine 60 by downward movement. The lowering platform 61 is retracted in the transverse direction in the lower position (dash-dotted positions) and then moved back into the upper receiving position for the next blank stack 57, by means of correspondingly driven links 62.

An der Unterseite des Zuschnittmagazins 60 werden Zu­schnitte nacheinander durch einen bekannten Abroller 63 entnommen und über Förderorgane einem in Fig. 4 schema­tisch dargestellten Faltrevolver 64 zugeführt.On the underside of the blank magazine 60, blanks are removed one after the other by a known unwinder 63 and fed to a folding turret 64 shown schematically in FIG.

Die Verarbeitung der Zuschnitte 23 innerhalb einer Verpak­kungsmaschine kann auch in anderer Weise erfolgen.The processing of the blanks 23 within a packaging machine can also take place in another way.
