    Die in den Zeichnungen dargestellten Beispiele befassen sich mit der Fertigung von quaderförmigen Verpackungen 10, und zwar von Zigaretten-Verpackungen des Typs Klappschachtel bzw. Hinge-Lid. Ein solcher Typ einer Verpackung 10 ist in Fig. 2 gezeigt. Die aus dünnem Karton bestehende Verpackung ist von einer Außenumhüllung 11 umgeben. Diese besteht aus einer durchsichtigen bzw. klarsichtigen Folie, insbesondere Kunststoffolie.The examples shown in the drawings deal with each other with the production of cuboid packaging 10, and of cigarette packaging of the hinged box type or Hinged-lid. Such a type of packaging 10 is shown in FIG. 2 shown. The packaging made of thin cardboard is from surrounded by an outer casing 11. This consists of a transparent or clear film, especially plastic film.

    Fig. 1 zeigt einen ausgebreiteten Zuschnitt für eine derartige Außenumhüllung 11. Für die Ingebrauchnahme der Verpackung 10 ist die Außenumhüllung 11 mit einem Aufreißstreifen 12 versehen. Dieser erstreckt sich in Längsrichtung des Zuschnitts der Außenumhüllung 11, die zugleich der Längserstreckung einer Folienbahn 13 für die Herstellung der Zuschnitte entspricht. Der Aufreißstreifen 12 verläuft über die gesamte Abmessung des Zuschnitts, derart, daß in einem oberen Bereich der Verpackung 10 die Außenumhüllung 11 ringsherum mit einem Aufreißstreifen 12 versehen ist. Bei Ingebrauchnahme der Verpackung 10 wird durch Betätigen des Aufreißstreifens 12 ein oberer, kappenförmiger Bereich der Außenumhüllung 11 abgetrennt.Fig. 1 shows a spread blank for such Outer wrapping 11. For using the packaging 10 is the outer covering 11 with a tear strip 12 provided. This extends in the longitudinal direction of the Cutting the outer envelope 11, which is also the longitudinal extent a film web 13 for the production of the blanks equivalent. The tear strip 12 runs over the overall dimension of the blank, such that in an upper Area of packaging 10 around the outer wrapper 11 is provided with a tear strip 12. When put into use the package 10 is opened by pressing the tear strip 12 an upper, cap-shaped area of the Outer casing 11 separated.

    Zum Erfassen des Aufreißstreifens 12 ist die Außenumhüllung 11 mit einer Zunge im Bereich eines freien Griffendes 14 des Aufreißstreifens 12 versehen.The outer covering is for gripping the tear strip 12 11 with a tongue in the region of a free handle end 14 of the Tear strip 12 provided.

    Das Griffende 14 des Aufreißstreifens 12 ist nicht immer leicht zu erkennen. Insbesondere bei Aufreißstreifen 12 aus durchsichtigem bzw. klarsichtigem Werkstoff ist es mühsam, das gegebenenfalls an einer Packungsfläche anliegende Griffende 14 zu finden. Aus diesem Grunde ist das Griffende 14 ganz oder teilweise mit einer farbigen bzw. dunklen Markierung versehen. Diese besteht im vorliegenden Fall aus einem farbigen bzw. dunklen Etikett oder Strip 15, der gesondert hergestellt und als eigenständiges Element an der gezeigten Position auf die Außenumhüllung 11 aufgebracht und mit dieser verbunden ist. Der Strip 15, der hier etwa deckungsgleich mit dem Aufreißstreifen 12 im Bereich des Griffendes 14 positioniert ist, erleichtert das Auffinden des Griffendes 14.The handle end 14 of the tear strip 12 is not always easy to recognize. Especially in the case of tear strips 12 transparent or clear material, it is tedious that, if applicable, on a packing surface Finding handle end 14. For this reason, the handle end 14 in whole or in part with a colored or dark marking Mistake. In the present case, this consists of a colored or dark label or strip 15, which is separate manufactured and as an independent element on the shown Position applied to the outer casing 11 and connected to it. The Strip 15, which is about here congruent with the tear strip 12 in the area of Handle end 14 is positioned, makes it easier to find the Handle end 14.

    Weiterhin ist die Außenumhüllung 11 bei dem Beispiel der Fig. 1 mit Bedruckungen versehen, und zwar mit bildlichen und/oder schriftlichen Markierungen, Marken oder dergleichen. Auch diese Bedruckungen bestehen aus kleinen Etiketten 16, die mit der Bedruckung gesondert gefertigt und auf die Außenumhüllung 11 aufgebracht werden, und zwar durch Kleben oder durch thermisches Siegeln.Furthermore, the outer casing 11 in the example of FIG. 1 provided with prints, with pictorial and / or written markings, brands or the like. Also these prints consist of small labels 16 with the printing made separately and on the outer wrapping 11 are applied, by gluing or by thermal sealing.

    Beide Kleinzuschnitte, nämlich Strip 15 und Etiketten 16, werden im Bereich einer Verpackungsmaschine bzw. eines Verpackungsaggregats, wie es beispielshaft in Fig. 3 gezeigt ist, auf die Folienbahn 13 zum Herstellen der Zuschnitte für die Außenumhüllung 11 aufgebracht. Strips 15 oder Etiketten 16 werden dabei von einem fortlaufenden Materialstreifen 17 abgetrennt und mit der Außenumhüllung 11 bzw. mit der Folienbahn 13 vor dem Abtrennen der Zuschnitte verbunden. Bei dem vorliegenden Ausführungsbeispiel besteht der Materialstreifen 17 aus einer selbstklebenden Bahn, so daß die Strips 15 bzw. Etiketten 16 positionsgerecht durch Klebung mit der Folienbahn 13 verbunden werden, und zwar auf der bei der fertigen Verpackung 10 innenliegenden Seite der Außenumhüllung 11. Für die Herstellung von Strips 15 kann der Materialstreifen 17 durchgehend gefärbt sein. Für die Herstellung von Etiketten 16 ist der Materialstreifen 17 mit Aufdrucken versehen, derart, daß einzelne, je mit einem Aufdruck versehene Etiketten 16 abgetrennt und mit der Folienbahn 13 verbunden werden können. Die Bedruckung des Materialstreifens 17 kann dabei auf der mit einem Klebstoff versehenen oder auf der klebstofffreien Seite des Materialstreifens 17 angebracht sein. Both small cuts, namely strip 15 and labels 16, are in the area of a packaging machine or a packaging unit, as shown by way of example in FIG. 3 is on the film web 13 for producing the blanks for the outer casing 11 applied. Strips 15 or labels 16 are from a continuous strip of material 17th separated and with the outer casing 11 or with the film web 13 connected before cutting the blanks. In which The present exemplary embodiment consists of the material strip 17 from a self-adhesive sheet, so that the strips 15 or Labels 16 in the correct position by gluing with the film web 13 are connected, namely on the finished Packaging 10 inner side of the outer wrapper 11. For the production of strips 15, the material strip 17 be colored throughout. For the production of labels 16, the material strip 17 is provided with prints, such that individual ones, each with an imprint Labels 16 separated and connected to the film web 13 can be. The printing of the material strip 17 can thereby on the one provided with an adhesive or on the Adhesive-free side of the material strip 17 attached his.

    Der Materialstreifen 17 ist von einer Streifenbobine 18 abziehbar. Er wird über Umlenkrollen 19 einem Anlegeaggregat 20 zugeführt. Im Bereich desselben werden die Strips 15 bzw. Etiketten 16 vom Materialstreifen 17 abgetrennt und an die Folienbahn 13 übertragen.The material strip 17 can be pulled off a strip bobbin 18. It is a guide unit 20 via pulleys 19 fed. In the area of the strips 15 or Labels 16 separated from the strip of material 17 and to the Transfer film web 13.

    Die Folienbahn 13 wird von einer Folienbobine 21 abgezogen und über Umlenkwalzen 22 in den Bereich des Anlegeaggregats 20 gefördert. Hier wird die Folienbahn 13 über Führungswalzen 23, 24 geleitet und über eine zwischen den Führungswalzen 23, 24 gelagerten Stützwalze 25. In deren Bereich wird der Strip 15 oder das Etikett 16 von oben an die Folienbahn 13 angelegt bzw. angedrückt.The film web 13 is pulled off a film reel 21 and over deflecting rollers 22 in the area of the application unit 20 promoted. Here the film web 13 over guide rollers 23, 24 guided and via a between the guide rollers 23, 24 supported backup roller 25. In the area of the strip 15 or the label 16 applied to the film web 13 from above or pressed.

    Das Anlegeaggregat 20 ist mit einem Förderorgan zum Transport eines Abschnitts des Materialstreifens 17 und des von diesem abgetrennten Strips 15 oder Etiketts 16 versehen. Es handelt sich dabei um eine Förderwalze 26. Der Materialstreifen 17 wird oben an den Umfang der Förderwalze 26 angelegt. Etwa im Bereich einer horizontalen Mittelebene werden die Strips 15 bzw. Etiketten 16 von dem Materialstreifen 17 abgetrennt. Im unteren Bereich der um eine horizontale Achse drehenden Förderwalze 26 werden die Strips 15 bzw. Etiketten 16 an die Folienbahn 13 übergeben.The application unit 20 is with a conveyor for transport a portion of the strip of material 17 and the portion thereof separated strips 15 or labels 16 provided. It deals is a conveyor roller 26. The material strip 17 is applied to the top of the conveyor roller 26 at the top. About in Strips 15 become the area of a horizontal central plane or labels 16 separated from the material strip 17. in the lower area of the conveyor roller rotating about a horizontal axis 26 the strips 15 or labels 16 on the film web 13 passed.

    Das vorliegende Ausführungsbeispiel bezieht sich auf die Anbringung eines Strips 15, so daß nachfolgend dieses stellvertretend für die in Betracht kommenden Etiketten, Zuschnitte etc. genannt wird.The present embodiment relates to the attachment a strip 15, so that this is representative for the labels, cuts to be considered etc. is called.

    Benachbart zur Förderwalze 26 und oberhalb derselben ist achsparallel eine Vorzugrolle 27 positioniert. Diese bewirkt den gesteuerten Antrieb bzw. Vorschub des Materialstreifens 17, derart, daß dieser taktweise - in Übereinstimmung mit dem Maschinentakt - um die Länge eines Strips 15 vorgeschoben wird. Die Vorzugrolle 27 ist hier zweckmäßigerweise mit gerändelter Mantelfläche ausgebildet, da bei einem Materialstreifen 17 mit einseitiger Klebefläche diese am Umfang der Vorzugrolle 27 anliegt.Is adjacent to the conveyor roller 26 and above it A preferred roller 27 is positioned axially parallel. This causes the controlled drive or feed of the material strip 17, such that this is clocked - in accordance with the Machine cycle - advanced by the length of a strip 15 becomes. The preferred roller 27 is expediently here knurled outer surface formed because of a strip of material 17 with one-sided adhesive surface on the circumference of the Preferred roller 27 abuts.

    Die Förderwalze wird taktweise angetrieben, und zwar je um eine volle Umdrehung. Während dieser Bewegung wird der Materialstreifen 17 lediglich um einen der Länge des Strips 15 entsprechenden Abschnitt weitergefördert. Im übrigen liegt der Materialstreifen 17 während der Drehung schlupfend bzw. gleitend am Umfang der Förderwalze 26 an.The conveyor roller is driven intermittently, each by a full turn. During this movement, the strip of material 17 only by one of the length of the strip 15 appropriate section promoted. Otherwise lies the material strip 17 slipping or rotating during the rotation sliding on the circumference of the conveyor roller 26.

    Der Materialstreifen 17 wird in einem mittleren Bereich an den Umfang der Förderwalze 26 angelegt. Diese ist mit einer in Radialrichtung nach außen vorstehenden, ringförmigen Anlagefläche 28 für Materialstreifen 17 und Etikett 16 versehen. Die Anlagefläche 28, die zweckmäßigerweise geringfügig breiter ist als der Materialstreifen 17, wird auf einer ringförmigen, radial nach außen vorspringenden Rippe 29 der Förderwalze 26 gebildet.The material strip 17 is in a middle area the circumference of the conveyor roller 26 is applied. This is with one in the radial direction outwardly projecting, annular contact surface 28 provided for material strips 17 and label 16. The contact surface 28, which is expediently slight is wider than the material strip 17, is placed on an annular, radially outwardly projecting rib 29 of the conveyor roller 26 formed.

    Der Materialstreifen 17 liegt etwa im Bereich eines Viertelkreises am Umfang der Förderwalze 26 bzw. der Rippe 29 an, und zwar bis zu einem Trennorgan. Dieses ist im vorliegenden Falle geringfügig oberhalb der horizontalen Mittelebene der Förderwalze 26 angeordnet. Das Trennaggregat besteht aus einem Trennmesser 30 und einem feststehenden Gegenmesser 31. Das Trennmesser 30 ist an der umlaufenden Förderwalze 26 angeordnet und ragt mit einer Schneidkante 32 geringfügig über den Umfang der Förderwalze 26 bzw. der Anlagefläche 28 hinweg. Dadurch kommt während jeder Umdrehung der Förderwalze 26 ein Trennschnitt im Materialstreifen 17 zustande, durch den ein Strip 15 abgetrennt wird.The material strip 17 lies approximately in the area of a quarter circle on the circumference of the conveyor roller 26 or the rib 29, up to a separating organ. This is in the present Case slightly above the horizontal median plane of the Conveyor roller 26 arranged. The separation unit consists of a cutting knife 30 and a fixed counter knife 31. The separating knife 30 is arranged on the rotating conveyor roller 26 and protrudes slightly with a cutting edge 32 the circumference of the conveyor roller 26 or the contact surface 28. As a result, the conveying roller 26 comes during each revolution a separating cut in the material strip 17, through which a strip 15 is separated.

    Das plattenförmige Trennmesser 30 ist auswechselbar an der Förderwalze 26 angebracht. Zu diesem Zweck ist im Querschnitt ein annähernd dreieckförmiger Ausschnitt 33 in der Förderwalze 26 gebildet. Das Trennmesser 30 liegt positionsgenau innerhalb dieses Ausschnitts 33. Das Trennmesser 30 wird dabei durch Halteschrauben 34 fixiert, die vom Außenumfang der Förderwalze 26 betätigt werden können. Der freie Bereich des Ausschnitts 33 ist durch ein Füllstück 35 abgedeckt, das einerseits das Trennmesser 30 in der Schneidposition fixiert und andererseits die Außenkontur der Förderwalze 26 ergänzt. Das Füllstück 35 ist ebenfalls mit quergerichteten Verbindungsschrauben 36 gehalten.The plate-shaped separating knife 30 is replaceable on the Conveyor roller 26 attached. For this purpose is in cross section an approximately triangular cutout 33 in the Conveyor roller 26 formed. The separating knife 30 is positioned exactly within this section 33. The cutting knife 30 is fixed by retaining screws 34, which are from the outer circumference the conveyor roller 26 can be operated. The free area the section 33 is covered by a filler 35, on the one hand the cutting knife 30 in the cutting position fixed and on the other hand the outer contour of the conveyor roller 26 added. The filler 35 is also transverse Connection screws 36 held.

    Die Halteschrauben 34 und die Verbindungsschrauben 36 - je zwei Stück - sind neben der Rippe 29 angeordnet, also in einem Bereich der Förderwalze 26 mit geringerem Durchmesser. Dadurch wird die zylindrische Anlagefläche 28 für den Materialstreifen 17 nicht unterbrochen.The retaining screws 34 and the connecting screws 36 - each two pieces - are arranged next to the rib 29, ie in a region of the conveyor roller 26 with a smaller diameter. This makes the cylindrical contact surface 28 for the strip of material 17 not interrupted.

    Der Materialstreifen 17 und der Strip 15 werden durch Saugluft am Umfang der Förderwalze 26 bzw. an der Anlagefläche 28 der Rippe 29 gehalten. Zu diesem Zweck ist die Rippe 29 ringsherum mit einer Reihe von in Umfangsrichtung nebeneinanderliegenden Saugbohrungen 37 versehen. Diese münden an der Anlagefläche 28. Die radial gerichteten Saugbohrungen 37 sind mit quergerichteten, also achsparallel verlaufenden Anschlußbohrungen 38 verbunden, die im Körper der Förderwalze 26 verlaufen und die mit ortsfesten Saugsegmenten 39 zeitweilig in Verbindung stehen. Die in Gestalt eines Teilkreisbogens ausgebildeten Saugsegmente 39 sind als offene Nuten in einem feststehenden Organ der Vorrichtung gebildet und mit einer Unterdruckquelle verbunden. Im vorliegenden Falle sind die Saugsegmente 39 auf einer der Förderwalze 26 zugekehrten Seite einer feststehenden Stützscheibe 40 angeordnet. Die Förderwalze 26 liegt an der Stützscheibe 40 an und gleitet an dieser während der Drehung. Bei dem vorliegenden Ausführungsbeispiel ist zwischen der Förderwalze 26 und der Stützscheibe 40 eine gesonderte Anlaufscheibe 41 positioniert. Diese besteht aus einem verschleißfesten Material. Die Anlaufscheibe 41 ist mit der Förderwalze 26 verbunden, dreht also mit dieser. Die Anschlußbohrungen 38 laufen durch die Anlaufscheibe 41 hindurch bis zum Saugsegment 39 im Bereich der Stützscheibe 40. Die Stützscheibe 40 wird federnd, nämlich durch eine Feder 42, an die drehende Anlaufscheibe 41 angedrückt.The material strip 17 and the strip 15 are by suction air on the circumference of the conveyor roller 26 or on the contact surface 28 the rib 29 held. For this purpose the rib is 29 all around with a series of circumferentially adjacent Provided suction holes 37. These lead to the Contact surface 28. The radially directed suction bores 37 are with transverse bores, i.e. axially parallel 38 connected in the body of the conveyor roller 26 run and temporarily with fixed suction segments 39 stay in contact. That in the form of a partial arc Trained suction segments 39 are in as open grooves a fixed organ of the device and formed with connected to a vacuum source. In the present case the suction segments 39 facing one of the conveyor roller 26 Side of a fixed support plate 40 is arranged. The Conveyor roller 26 lies against the support disk 40 and slides on this during the rotation. In the present embodiment is between the conveyor roller 26 and the support disc 40 positioned a separate thrust washer 41. This consists of a wear-resistant material. The thrust washer 41 is connected to the conveyor roller 26, rotates so with this. The connection bores 38 run through the Thrust washer 41 through to the suction segment 39 in the area the support disc 40. The support disc 40 becomes resilient, namely by a spring 42 to the rotating thrust washer 41 pressed.

    Bei dem gezeigten Ausführungsbeispiel erstreckt sich das Saugsegment 39 annähernd über den halben Umfang der Förderwalze 26, und zwar von oben im Bereich der Zuführung des Materialstreifens 17 bis etwa zur Übergabeposition des Strips 15 an die Folienbahn 13. In diesem Umfangsbereich sind die Saugbohrungen 37 wirksam.In the embodiment shown, this extends Suction segment 39 approximately over half the circumference of the conveyor roller 26, from above in the area of the feed of the material strip 17 to about the transfer position of the strip 15 to the film web 13. In this circumferential area Suction bores 37 effective.

    Die Folienbahn 13 wird in einem Übergabebereich für den Strip 15 durch eine besondere Führung, im vorliegenden Falle durch die Stützwalze 25 in Verbindung mit den zu beiden Seiten angeordneten Führungswalzen 23, 24, in Richtung auf den unteren Umfangsbereich der Förderwalze 26 ausgelenkt.The film web 13 is in a transfer area for the strip 15 through a special tour, in the present case through the support roller 25 in connection with the arranged on both sides Guide rollers 23, 24, towards the lower one Circumferential region of the conveyor roller 26 deflected.

    Damit bei der Übergabe des Strips 15 an die Folienbahn 13 diese nicht durch das über die Ebene der Anlagefläche 25 hinwegragende Trennmesser 30 zerstört wird, ist zwischen dem Umfang der Förderwalze 26 bzw. der Rippe 29 einerseits und der Folienbahn 13 auf der Stützwalze 25 ein ausreichender Abstand vorgesehen, so daß die Schneidkante 32 des Trennmessers 30 mit Sicherheit berührungslos an der Folienbahn 13 vorbeibewegt werden kann. Für die Übergabe des Strips 15 muß dieser Abstand mindestens zeitweilig überwunden werden, damit die Übergabe erfolgen kann.So that when the strip 15 is transferred to the film web 13 this is not due to the fact that it projects beyond the level of the contact surface 25 Cutting knife 30 is destroyed, is between the Scope of the conveyor roller 26 and the rib 29 on the one hand and the film web 13 on the support roller 25 a sufficient distance provided so that the cutting edge 32 of the cutting knife 30 moved past the film web 13 without contact can be. For the transfer of the strip 15, this must Distance at least temporarily to be overcome so that the Handover can take place.

    Zu diesem Zweck ist bei dem vorliegenden Ausführungsbeispiel die Förderwalze 26 mit einem Haltesegment 43 ausgerüstet. Dieses ist Teil der Förderwalze 26 und relativ zu dieser bewegbar, im vorliegenden Falle in Radialrichtung. In der Normalstellung ist das Haltesegment 43 bündig mit der Förderwalze 26 positioniert. Eine radial außenliegende Haltefläche 44 des Haltesegments 43 verläuft dabei bündig mit der Anlagefläche 28 der Rippe 29. Bei dem vorliegenden Beispiel hat das Haltesegment 43 überwiegend die Breite der Rippe 29, ist also Teil derselben. For this purpose, the present embodiment the conveyor roller 26 is equipped with a holding segment 43. This is part of the conveyor roller 26 and movable relative to it, in the present case in the radial direction. In the normal position the holding segment 43 is flush with the conveyor roller 26 positioned. A radially outer holding surface 44 of the holding segment 43 runs flush with the contact surface 28 of the rib 29. In the present example it has the holding segment 43 is predominantly the width of the rib 29 so part of the same.

    Das Haltesegment 43 ist mit der Haltefläche 44 so positioniert, daß ein vorn liegendes Endstück des Materialstreifens 17 durch entsprechende Vorschubbewegung der Vorzugrolle 27 an der Haltefläche 44 des Haltesegments 43 anliegt. Auch in diesem Bereich ist eine Reihe von in Umfangsrichtung dicht aneinanderliegenden Saugbohrungen 45 vorgesehen, um das Ende des Materialstreifens 17 bzw. den von diesem abgetrennten Strip 15 zu halten. Das Haltesegment 43 ist zu diesem Zweck so positioniert, daß es in Umfangsrichtung der Rippe 29 unmittelbar an das Trennmesser 30 anschließt. Der abgetrennte Strip 15 wird demnach in nahezu voller Länge durch das Haltesegment 43 erfaßt.The holding segment 43 is positioned with the holding surface 44 that a front end of the strip of material 17 by corresponding feed movement of the preferred roller 27 the holding surface 44 of the holding segment 43 abuts. Also in this area is a series of circumferentially dense adjacent suction bores 45 are provided around the end of the material strip 17 or those separated from it Hold Strip 15. The holding segment 43 is for this purpose positioned so that it is immediately in the circumferential direction of the rib 29 connects to the cutting knife 30. The severed Strip 15 is therefore almost full length through the holding segment 43 recorded.

    Zur Übergabe des Strips 15 an die Folienbahn 13 wird im unteren Bereich der Förderwalze 26 das Haltesegment 43 nach außen verschoben, also über die Umfangsfläche der Förderwalze 26 hinaus. Die Bewegung des Haltesegments 43 ist so gesteuert, daß der Abstand zur Folienbahn 13 im Bereich der Stützwalze 25 überwunden und der Strip 15 an die Folienbahn 13 durch das Haltesegment 43 angelegt bzw. angedrückt wird. Danach kehrt das Haltesegment 43 bei weiterer Drehung der Förderwalze 26 in die Ausgangsstellung zurück.To transfer the strip 15 to the film web 13 is in the lower Area of the conveyor roller 26, the holding segment 43 to the outside moved, that is, over the circumferential surface of the conveyor roller 26 out. The movement of the holding segment 43 is controlled that the distance to the film web 13 in the region of the support roller 25 overcome and the strip 15 to the film web 13 through the Holding segment 43 is applied or pressed. After that returns the holding segment 43 upon further rotation of the conveyor roller 26 back to the starting position.

    Die gesteuerte Bewegung des Haltesegments 43 in Radialrichtung wird im vorliegenden Falle durch mechanische Organe bewirkt. Seitlich ist zu diesem Zweck ein Ansatz 46 am Haltesegment 43 gebildet. An diesem Ansatz 46 wiederum ist eine seitwärts gerichtete Tastrolle 47 angebracht. Diese läuft auf einer geschlossenen, ringförmigen Kurvenbahn 48 ab. Diese ist Teil einer Führungsnut 49 in einer feststehenden, konzentrisch zur Förderwalze 26 angeordneten Scheibe 50.The controlled movement of the holding segment 43 in the radial direction is effected in the present case by mechanical organs. For this purpose there is an extension 46 on the side of the holding segment 43 formed. At this approach 46 in turn is one sideways-facing feeler roller 47 attached. This runs up a closed, annular cam track 48. This is Part of a guide groove 49 in a fixed, Disc 50 arranged concentrically with the conveyor roller 26.

    Die Saugbohrungen 45 des Haltesegments 43 sind in der im Zusammenhang mit den Saugbohrungen 37 beschriebenen Weise mit dem Saugsegment 39 während der Drehung verbunden. An die Saugbohrungen 45 schließen zu diesem Zweck Anschlußbohrungen 51 an, die im vorliegenden Falle mindestens in einem dem Saugsegment 39 zugekehrten Bereich mit einem länglichen bzw. langlochartigen Querschnitt ausgestaltet sind. Dadurch ist gewährleistet, daß mindestens ein Teilbereich der Anschlußbohrungen 51 auch während der radialen Verschiebung des Haltesegments 43 mit dem gemeinsamen Saugsegment 39 in Verbindung bleibt.The suction bores 45 of the holding segment 43 are related described with the suction holes 37 with connected to the suction segment 39 during the rotation. To the Suction bores 45 close connection bores for this purpose 51, which in the present case at least in one of the Suction segment 39 facing area with an elongated or slot-like cross section are designed. This is ensures that at least a portion of the connection holes 51 also during the radial displacement of the holding segment 43 in connection with the common suction segment 39 remains.

    Im Übergabebereich des Strips 15 an die Folienbahn 13, also etwa in der vertikalen Mittelebene der Förderwalze 26, endet das Saugsegment 39. Stattdessen ist hier eine Entlüftungsbohrung 52 vorgesehen, so daß in der radialen Endstellung der Strip 15 nicht mehr durch Saugluft am Haltesegment 43 fixiert ist.In the transfer area of the strip 15 to the film web 13, that is approximately in the vertical central plane of the conveyor roller 26 ends the suction segment 39. Instead there is a vent hole 52 provided so that in the radial end position Strip 15 no longer fixed by suction air on the holding segment 43 is.

    Die kontinuierlich drehend angetriebene Förderwalze 26 sitzt auf dem Ende einer Antriebswelle 53. Ein zur Förderwalze 26 benachbarter Endbereich der Antriebswelle 53 ist durch ein Kegelrollenlager 54 in einer Gehäusewand 55 der Verpackungsmaschine abgestützt.The continuously rotating conveyor roller 26 is seated on the end of a drive shaft 53. One to the conveyor roller 26 adjacent end region of the drive shaft 53 is by a Tapered roller bearings 54 in a housing wall 55 of the packaging machine supported.

    Die Stützscheibe 40 auf der gegenüberliegenden Seite der Förderwalze 26 ist an einer queraxial verlaufenden Traverse 56 angebracht. Diese ist ebenfalls mit dem Traggestell bzw. Maschinengehäuse verbunden. Die Traverse verläuft in einer diametralen Ausnehmung 57 der Stützscheibe 40.The support disc 40 on the opposite side of the conveyor roller 26 is on a cross-axial traverse 56 appropriate. This is also with the support frame or machine housing connected. The traverse runs in one diametrical recess 57 of the support disk 40.

    Bei der Anbringung von (bedruckten) Etiketten 16 an der Folienbahn 13 wird ähnlich verfahren. Es werden demnach Abschnitte eines Materialstreifens 17 mit den Etiketten 16 abgetrennt. Dabei können auch je Drehung der Förderwalze 26 mehrere Etiketten 16 nacheinander abgetrennt und der Folienbahn 13 in kürzeren Abständen zugeführt werden. Alternativ kann auch die Förderwalze während.einer Drehung mit relativ höherer Geschwindigkeit angetrieben werden, so daß während des Vorzugs der Folienbahn 13 um einen Zuschnitt für die Außenumhüllung 11 mehrere Etiketten 16 nacheinander übertragbar sind. When attaching (printed) labels 16 to the film web 13 is handled similarly. So there will be sections a strip of material 17 separated with the labels 16. It is also possible for each rotation of the conveying roller 26 several labels 16 separated one after the other and the film web 13 can be fed at shorter intervals. alternative the conveyor roller can also be rotated relatively be driven at a higher speed so that during the preference of the film web 13 by a cut for the Outer wrapping 11 several labels 16 can be transferred one after the other are.

    Die Relativbewegung zur Übergabe des Strips 15 an die Folienbahn 13 kann auch durch eine andere Relativbewegung erfolgen, zum Beispiel durch kurzzeitiges Bewegen der Folienbahn 13 in Richtung zur Förderwalze 26. Alternativ kann auch das Trennmesser 30 verschiebbar gelagert sein, so daß es zur Übergabe des Strips 15 an die Folienbahn 13 kurzzeitig aus der Schneidstellung nach innen in die Förderwalze 26 zurückgezogen wird. Bei dieser Lösung bedarf es keines Abstandes zwischen der Förderwalze 26 und der Folienbahn 13.The relative movement for transferring the strip 15 to the film web 13 can also be done by another relative movement, for example by briefly moving the film web 13 in Direction to the conveyor roller 26. Alternatively, the cutting knife 30 be slidably mounted so that it can be handed over of the strip 15 to the film web 13 briefly from the Cutting position withdrawn inwards into the conveyor roller 26 becomes. With this solution there is no distance between the conveyor roller 26 and the film web 13.

    Die mit einem Strip 15 und/oder gegebenenfalls mehreren Etiketten 16 versehene Folienbahn wird weitertransportiert. Dabei wird ein von einer Fadenbobine 58 abgezogener Aufreißstreifen 12 an die Folienbahn 13 fortlaufend angelegt, und zwar so, daß der Strip 15 durch den Aufreißstreifen 12 überdeckt wird. Danach gelangt die so komplettierte Folienbahn 13 in den Bereich eines Zuschnittaggregats 59. Hier werden die einzelnen Zuschnitte für die Außenumhüllung (Fig. 1) hergestellt und in bekannter Weise um die Verpackungen 10 herumgefaltet.The one with a strip 15 and / or possibly several labels 16 provided film web is transported on. there becomes a tear strip pulled from a thread bobbin 58 12 continuously applied to the film web 13, and in such a way that the strip 15 is covered by the tear strip 12 becomes. The film web 13 thus completed then arrives in the area of a cutting unit 59. Here the individual blanks for the outer wrapping (Fig. 1) produced and in a known manner around the packaging 10 folded around.

    Die Förderwalze 26 kann auch mehrere, insbesondere zwei längs des Umfangs verteilte Trennmesser 30 aufweisen, wobei der Arbeitstakt der Förderwalze 26 entsprechend angepaßt ist. In besonderen Fällen kann die Förderwalze 26 auch taktweise angetrieben werden, insbesondere wenn zwei oder mehr Strips, Etiketten oder dergleichen pro Arbeitstakt verarbeitet werden.The conveyor roller 26 can also have several, in particular two, lengthways Distributing knife 30 distributed around the circumference, the work cycle the conveyor roller 26 is adapted accordingly. In In special cases, the conveyor roller 26 can also be cyclically driven especially if two or more strips Labels or the like are processed per work cycle.
