Die Etikettiermaschine 1 ist zum Etikettieren von offenen, konischen Bechern 2 aus Kunststoff, wie sie beispielsweise für Joghurt verwendet werden, eingerichtet. Sie weist ein Gehäuse 17 auf, an dessen Oberseite ein Drehtisch 3, ein Einlaufstern 10 und ein Auslaufstern 12, alle mit senkrechter Drehachse, sowie eine Etikettierstation 5 in Form eines Spenders für Selbstklebeetiketten angeordnet sind. Der Drehtisch 3, der Einlaufstern 10 und der Auslaufstern 12 werden durch nicht gezeigte Antriebseinrichtungen innerhalb des Gehäuses i7 in Pfeilrichtung kontinuierlich angetrieben.The labeling machine 1 is for labeling open, conical cups 2 made of plastic, such as used for yogurt set up. She instructs Housing 17 on the top of which a turntable 3, a Inlet star 10 and an outlet star 12, all with vertical Axis of rotation, and a labeling station 5 in the form of a Dispensers for self-adhesive labels are arranged. The Turntable 3, the inlet star 10 and the outlet star 12 are within drive means, not shown of the housing i7 continuously driven in the direction of the arrow.

Im Drehtisch 3 sind gleichmäßig über den Umfang verteilt mehrere Wellen 8 mit polygonförmigem Querschnitt drehbar gelagert und zwar parallel zur Drehachse des Drehtisches 3. Auf jeder Welle 8 ist ein sich nach oben hin konisch verjüngender Dorn 4 mit einer entsprechend polygonförmigen Bohrung höhenverschiebbar aufgenommen. Innerhalb des Drehtisches 3 ist eine erste Kurvensteuerung 15 angeordnet, welche bei einem Umlauf des Drehtisches 3 den Wellen 8 bzw. Dornen 4 im Bereich der Etikettierstation 5 und ggf. nicht gezeigter Etikettenandrückorgane die gewünschte Dreh- oder Schwenkbewegung erteilt. Für die Höhenbewegung der Dorne 4 ist eine zweite Kurvensteuerung 16 vorgesehen, welche bei einem Umlauf des Drehtisches 3 den Dornen 4 im Bereich des Einlaufsterns 10 und Auslaufsterns 12 die gewünschte Hubbewegung erteilt.In the turntable 3 are evenly distributed over the circumference several shafts 8 with a polygonal cross section rotatable stored and parallel to the axis of rotation of the turntable 3. On each shaft 8 is a conical upwards tapering mandrel 4 with a correspondingly polygonal Bore height adjustable added. Within the A first cam control 15 is arranged on the rotary table 3, which, when the rotary table 3 rotates, the shafts 8 or Thorns 4 in the area of the labeling station 5 and possibly not shown label pressing organs the desired rotary or Swivel movement granted. For the height movement of the mandrels 4 a second cam control 16 is provided, which at one revolution of the rotary table 3 the thorns 4 in the area of Inlet star 10 and outlet star 12 the desired Lift movement issued.

Jedem Dorn 4 ist eine ringförmige Aufnahme 6 für den offenen, unteren Rand eines Bechers 2 zugeordnet, die konzentrisch zum Dorn 4 ohne Verbindung mit diesem angeordnet ist. Wie die Fig. 2 zeigt, sind die Aufnahmen 6 an den oberen Enden von senkrechten Stangen 18 befestigt, derart, daß sie höhenfest in einer gemeinsamen horizontalen Transportebene liegen. Am äußeren Rand der kreisförmigen Aufnahmen 6 ist eine erhöhte, abgerundete Zentrierfläche 7 ausgebildet, die entsprechend dem äußeren Becherrand kreisförmig ist und diesen mit leichtem Spiel umfaßt. Durch die Zentrierfläche 7 werden die Becher 2 somit exakt in der Aufnahme 6 gegenüber den Dornen 4 ausgerichtet. Die Höhe der Zentrierflächen 7 ist relativ gering, so daß, in Verbindung mit ihrer Rundung oder Abschrägung, die Becher 2 leicht in die Aufnahmen 6 hinein- bzw. aus diesen herausschlüpfen können.Each mandrel 4 is an annular receptacle 6 for the assigned to the open, lower edge of a cup 2, the arranged concentrically to the mandrel 4 without connection to it is. 2 shows, the recordings 6 are on the upper Fixed ends of vertical rods 18 such that they fixed in height in a common horizontal transport level lie. At the outer edge of the circular receptacles 6 is an increased, rounded centering surface 7 is formed is circular according to the outer rim of the cup and includes this with easy play. Through the centering surface 7 the cups 2 are thus exactly opposite in the receptacle 6 the thorns 4 aligned. The height of the centering surfaces 7 is relatively low, so that, in connection with their rounding or Bevel, the cups 2 slightly into the receptacles 6 or can slip out of these.

Auf den jeweils zu einer Aufnahme 6 gehörenden parallelen Stangen 18, die auf dem Drehtisch 3 befestigt sind, ist ein U-förmiger Schlitten 19 höhenbeweglich gelagert. Dieser greift einerseits mittels Nasen in eine Ringnut am zugehörigen Dorn 4 und andererseits mittels einer Rolle 27 in eine ortsfeste Hubkurve 20 ein. Die letztgenannten Teile bilden die zweite Kurvensteuerung 16 des Hub-Drehgetriebes 9. Auch die erste Kurvensteuerung 15 weist eine ortsfeste Nutkurve 21 auf, in welche über Getriebe mit den Wellen 8 verbundene Rollenhebel 28 eingreifen. Die Hubkurve 20 und die Nutkurve 21 sind derart geformt, daß sich die weiter unten beschriebene Funktion der Etikettiermaschine 1 einstellt.On the parallel to each receptacle 6 Rods 18, which are attached to the turntable 3, is a U-shaped carriage 19 is mounted so as to be vertically movable. This engages in an annular groove on the one hand by means of lugs associated mandrel 4 and on the other hand by means of a roller 27 in a fixed stroke curve 20 a. The latter parts form the second cam control 16 of the lifting rotary gear 9. The first cam controller 15 also has a fixed one Groove curve 21, in which gear with the shaft 8 engage connected roller lever 28. The stroke curve 20 and the Groove curve 21 are shaped such that the further below sets described function of the labeling machine 1.

Jeder Dorn 4 weist eine zentrale Bohrung mit einer in die obere Stirnfläche einmündenden Öffnung 14 auf. Diese ist über eine weitere zentrale Bohrung in der Welle 8 und eine Querbohrung mit einem auf den Drehtisch 3 angeordneten Drehverteiler 22 verbunden. Die Drehverteiler 22 aller Dorne 4 stehen mit einem konzentrisch zur Drehachse des Drehtisches 3 angeordneten Zentralverteiler 24 in Verbindung, der sie an den gewünschten Stellen ihrer Umlaufbahn wahlweise mit einer Vakuumquelle, einer Druckluftquelle oder der Atmosphäre verbindet. Der Zentralverteiler 24 ist derart ausgebildet, daß sich die nachstehende Funktion der Etikettiermaschine 1 ergibt.Each mandrel 4 has a central bore with one in the upper end face opening opening 14. This is over another central bore in shaft 8 and one Cross hole with a arranged on the turntable 3 Rotary distributor 22 connected. The rotary distributor 22 of all mandrels 4 are concentric with the axis of rotation of the turntable 3 arranged central distributor 24 in connection of them to the desired points of your orbit with either Vacuum source, a compressed air source or the atmosphere connects. The central distributor 24 is designed such that the following function of the labeling machine 1 results.

Im normalen Etikettierbetrieb werden die in Form einer senkrechten Säule mit nach unten weisender Öffnung gestapelten Becher 2 durch eine herkömmliche Zuteilvorrichtung 23, die über dem Einlaufstern 10 stationär angeordnet ist, in dessen Taschen eingeworfen. Die Zuteilvorrichtung 23 weist beispielsweise mehrere nicht dargestellte, synchron zum Einlaufstern 10 angetriebene senkrechte Förderschnecken auf, welche die Becher 2 teilungsgerecht exakt in den Einlaufstern 10 einführen. Dessen Taschen sind gegenüber dem Querschnitt der Becher 2 in ümlaufrichtung erweitert, so daß ausreichend Zeit für die Zufuhr der Becher 2 zur Verfügung steht.In normal labeling, they are in the form of a vertical column with opening pointing downwards stacked cup 2 by a conventional one Allotment device 23, which is stationary over the inlet star 10 is arranged, thrown into the pockets. The Allotment device 23 does not have several, for example shown, driven synchronously to the inlet star 10 vertical screw conveyors, which the cups 2 Insert exactly into the inlet star 10 according to the division. Its pockets are in relation to the cross section of the cup 2 in Umlaufrichtung expanded so that enough time for the Feed the cup 2 is available.

Anschließend werden die Becher 2 durch die Taschen des Einlaufsterns 10 zum Drehtisch 3 transportiert, wobei sie mit ihrem offenen Randbereich auf der ebenen Gleitfläche 11 aufliegen und durch einen zwischen Einlaufstern 10 und Auslaufstern 12 angeordneten stationären Führungsbogen 25 exakt geführt werden. Die Gleitfläche 11 liegt auf Höhe des oberen Randes der Zentrierfläche 7 der Aufnahmen 6. Durch die Taschen des Einlaufsterns 10, die Gleitfläche 11 und den Führungsbogen 25 wird jeder Becher 2 exakt mittig über eine Aufnahme 6 geschoben, wonach er zwischen die Zentrierfläche 7 einsinkt und mit seinem unteren Rand auf der Aufnahme 6 aufliegt. Der entsprechende Dorn 4 nimmt hierbei seine in Fig. 2 auf der rechten Seite gezeigte untere Endposition ein, in welcher er vollständig unter seine Aufnahme 6 abgesenkt und seine Öffnung 14 mit der Atmosphäre verbunden ist. Statt dessen ist es auch möglich, die obere Stirnfläche des Dorns 4 mit dem oberen Rand der Zentrierfläche 7 fluchten zu lassen.Then the cups 2 through the pockets of the Inlet star 10 transported to the rotary table 3, with its open edge area on the flat sliding surface 11 rest and by a between inlet star 10 and Spout star 12 arranged stationary guide bend 25 be guided exactly. The sliding surface 11 is at the level of upper edge of the centering surface 7 of the receptacles 6 Pockets of the inlet star 10, the sliding surface 11 and the Guide bow 25, each cup 2 is exactly centered over a Recording 6 pushed, after which he between the centering surface 7th sinks and with its lower edge on the recording 6 lies on. The corresponding mandrel 4 takes its in 2 a lower end position shown on the right, in which it is completely lowered under its receptacle 6 and its opening 14 is connected to the atmosphere. Instead of which is also possible, the upper end face of the mandrel 4th to align with the upper edge of the centering surface 7.

Nunmehr wird der Dorn 4 mit der Vakuumquelle verbunden, um den Becher 2 sicher zu positionieren, und er wird unter Einwirkung der zweiten Kurvensteuerung 16 über die in Fig. 2 in der Mitte gezeigte Zwischenposition in die auf der linken Seite gezeigte obere Endposition angehoben. In der Endphase dieser Hubbewegung wird der betreffende Becher 2 von der Aufnahme 6 etwas abgehoben und dann ausschließlich durch den Dorn 4 getragen, festgehalten durch das weiter wirkende Vakuum an der Öffnung 14.Now the mandrel 4 is connected to the vacuum source in order position the cup 2 securely and it will be under Action of the second cam controller 16 via that in FIG. 2 intermediate position shown in the middle to that on the left Upper end position shown on the side raised. In the final phase this lifting movement is the relevant cup 2 from the Recording 6 slightly lifted and then exclusively through the Mandrel 4 worn, held by the further acting Vacuum at the opening 14.

In dieser Position passiert der Dorn 4 mit dem aufgesteckten und angesaugten Becher 2 die Etikettierstation 5, wo ihm unter Einfluß der ersten Kurvensteuerung 15 eine Schwenkbewegung in Umlaufrichtung erteilt wird. Dabei wird ein Selbstklebeetikett an die Wandung des Bechers 2 angeheftet und angedrückt, erforderlichenfalls unter Einwirkung zusätzlicher Andrückrollen oder dgl..In this position the mandrel 4 passes with the plugged on and suction cup 2 the labeling station 5 where it under the influence of the first cam controller 15 Swiveling movement in the direction of rotation is issued. Doing so a self-adhesive label on the wall of the cup 2 pinned and pressed, if necessary under Action of additional pressure rollers or the like.

Nunmehr wird das Vakuum an der Öffnung 14 abgeschaltet und der Dorn wird umgekehrt wie in Fig. 2 dargestellt aus der oberen Endposition über eine Zwischenposition in die untere Endposition abgesenkt. Um das Lösen des Bechers 2 vom Dorn 4 zu erleichtern wird hierbei vorübergehend Druckluft der Öffnung 14 zugeleitet. In der Anfangsphase der Absenkbewegung trifft der Becher 2 mit seinem unteren Rand wieder auf die Aufnahme 6 auf und wird dort durch die Zentrierfläche 7 fixiert. Die Aufnahme 6 mit dem Becher 2 läuft nun zum Auslaufstern 12, wo der Becher 2 durch den Führungsbogen 25 aus der Aufnahme 6 heraus über die Zentrierfläche 7 hinweg auf die auslaufseitige Gleitfläche 13 und dabei in eine Tasche des Auslaufsterns 12 hineingeleitet wird. Die Gleitfläche 11 ist wiederum auf Höhe des oberen Randes der Zentrierfläche 7 angeordnet. Durch den Auslaufstern 12, die Gleitfläche 13 und den Führungsbogen 25 wird der etikettierte Becher 2 einem die Becher 2 abführenden Förderband 26 zugeführt. Während des Herausleitens des Bechers 2 aus der Aufnahme 6 befindet sich der entsprechende Dorn 4 vollständig unterhalb der Aufnahme 6 und ist mit der Atmosphäre verbunden, so daß er diesen Vorgang nicht beeinflußt. Im Bereich zwischen Auslaufstern 12 und Einlaufstern 10 verbleibt der Dorn 4 in seiner unteren Endposition, bis er nach dem Aufsetzen eines Bechers 2 auf seine Aufnahme 6 wiederum mit seinem Anstieg beginnt.The vacuum at the opening 14 is now switched off and the mandrel is reversed as shown in Fig. 2 from the upper end position via an intermediate position in the lower End position lowered. To release the cup 2 from the mandrel 4 This will temporarily facilitate compressed air Opening 14 fed. In the initial phase of the lowering movement the cup 2 meets with its lower edge again Recording 6 and is there through the centering surface 7th fixed. The receptacle 6 with the cup 2 now runs to Outlet star 12, where the cup 2 through the guide arc 25th out of the receptacle 6 over the centering surface 7 on the outlet-side sliding surface 13 and thereby in a Pocket of the outlet star 12 is passed. The Sliding surface 11 is in turn at the level of the upper edge of the Centering surface 7 arranged. Through the outlet star 12, the Sliding surface 13 and the guide sheet 25 is the labeled Bucket 2 to a conveyor belt 26 that removes the buckets 2 fed. During the extraction of the cup 2 from the Recording 6 is the corresponding mandrel 4 completely below the shot 6 and is with the atmosphere connected so that it does not affect this process. in the Area between outlet star 12 and inlet star 10 the mandrel 4 remains in its lower end position until it after placing a cup 2 on its receptacle 6 again begins with its rise.

Die Etikettierstation 5 (Fig. 3) weist eine Transfertrommel 33 mit einer konisch geformten Mantelfläche 37 und eine Etikettenzuführstation 40 auf, die im wesentlichen aus einer die Mantelfläche tangierenden Spendekante 32 und einer gesteuert intermittierend antreibbaren Etikettenbandvorschubeinrichtung (nicht dargestellt) für die auf einem Trägerband 31 angebrachten Haftetiketten 30, sogenannten Selbstklebeetiketten, besteht. Im Bereich der Spendekante 32 lösen sich die einzelnen Etikettenzuschnitte vom Trägerband 31. Das von der Spendekante wegfuhrende, nunmehr etikettenfreie Trägerband 31' wird in an sich bekannter Weise aufgewickelt.The labeling station 5 (FIG. 3) has a transfer drum 33 with a conically shaped surface 37 and a Label feed station 40, which consists essentially of a the outer surface tangent dispensing edge 32 and one controlled driven intermittently Label tape feed device (not shown) for the adhesive labels 30 attached to a carrier tape 31, so-called self-adhesive labels. In the field of Dispensing edge 32 detach the individual label blanks from the carrier tape 31. The one leading away from the dispensing edge now label-free carrier tape 31 'becomes in itself known way wound.

Im konischen Mantel der Transfertrommel 33 sind in regelmäßigen Abständen umfangsmäßig versetzt Vakuumbohrungen 36 vorhanden, mit deren Hilfe die sich an der Spendekante 32 vom Trägerband ablösende, vorlaufende Kante 30a eines Etikettenzuschnitts 30 erfasst werden kann. Insoweit stimmt der Grundaufbau der Etikettierstation 5 mit der EP 0 501 105 B1 überein. In the conical shell of the transfer drum 33 are in Vacuum holes offset circumferentially at regular intervals 36 available, with the help of which on the dispensing edge 32 leading edge 30a separating from the carrier tape Label cut 30 can be detected. So far that's true the basic structure of the labeling station 5 with EP 0 501 105 B1 match.

Die entscheidende Besonderheit besteht nun darin, dass die Vakuumbohrungen 36 sich nicht direkt in der Mantelfläche 37 der Transfertrommel befinden, sondern jeweils auf einem leistenförmigen Schieber 34, der in der konischen Mantelfläche 37 im wesentlichen quer zur Umlaufebene E (Fig.4) der Transfertrommel 33 gesteuert verschiebbar gelagert ist und dessen Oberfläche bündig in der Mantelfläche liegt oder geringfügig radial nach außen überstehend ausgebildet ist.The decisive peculiarity is that the Vacuum bores 36 are not directly in the lateral surface 37 the transfer drum, but each on one strip-shaped slide 34, which in the conical Shell surface 37 substantially transversely to the plane of rotation E (Fig.4) of the transfer drum 33 can be moved in a controlled manner is stored and its surface is flush with the outer surface lies or protrudes slightly radially outwards is trained.

Die Steuerung der Schieber 34 erfolgt durch eine im Inneren der Transfertrommel verdrehfest angeordnete Steuerkurve 38 (Nutkurve) in Verbindung mit einem die Steuerkurve abtastenden, mit dem Schieber 34 verbundenen Steuerelement 39, z.B. Kurvenrolle, in Abhängigkeit der Drehstellung der Transfertrommel.The control of the slide 34 is carried out by an inside of the transfer drum arranged in a rotationally fixed control curve 38 (Groove curve) in connection with a the control curve sensing control connected to the slider 34 39, e.g. Cam roller, depending on the rotational position of the Transfer drum.

Die in Fig. 3 abgebildete Transfertrommel 33 besitzt vier in Umfangsrichtung mit gleichmäßigem Abstand versetzte Vakuumschieber 34 und wird derart kontinuierlich synchron zum Drehtisch 3 angetrieben, dass sich die Transfertrommel beim Vorbeilaufen von vier Bechern 2 einmal vollständig dreht, wobei immer dann, wenn ein Becher die Transfertrommel 33 unter kurzzeitiger Linienberührung passiert, einer der Vakuumschieber 34 die vorlaufende Etikettenkante 30a eines Etiketts stellungsgerecht mit dem Becher in Eingriff bringt. In diesem Augenblick wird das Etikett durch Unterbrechen des Vakuums in dem entsprechenden Vakuumschieber freigegeben bzw. durch Einleiten von Druckluft die Übergabe auf den Becher unterstützt. Diese Vorgänge werden in bekannter Weise gesteuert, so dass auf eine detailliertere Beschreibung verzichtet wird. The transfer drum 33 shown in FIG. 3 has four in Stagger the circumferential direction with an even distance Vacuum slide 34 and is continuously synchronized to Turntable 3 driven that the transfer drum at Passing four cups 2 once completely rotates, wherever a cup transfers drum 33 happens under brief line contact, one of the Vacuum slide 34 the leading label edge 30a one Engages the label in the correct position with the mug. At this moment the label is removed by interrupting the Vacuum released in the corresponding vacuum slide or by transferring compressed air to the cup supported. These operations are done in a known manner controlled so that on a more detailed description is waived.

Aufgrund dieser gesteuert beweglichen Vakuumschieber 34 in der ansonsten keine Vakuumbohrungen aufweisenden Transfertrommel 33 besteht die Möglichkeit, das in Richtung L zulaufende Etikettenband 31, auf dem die einzelnen Etikettenzuschnitte 30 mit ihrer jeweiligen Symmetrieachse 30b im rechten Winkel zu der oberen und unteren Bandlängskante 31a, 31b ausgerichtet sind, schräg zur Umlaufebene E der Transfertrommel 33 tangential an deren Mantelfläche so anzuordnen, dass die vorlaufende Etikettenkante 30a parallel zur Längserstreckung bzw. Führungsachse des Vakuumschiebers 34 zugeführt und abgespendet wird.Due to this controlled movable vacuum slide 34 in the one that otherwise has no vacuum bores Transfer drum 33 there is the possibility that in the direction L tapering label tape 31 on which the individual Label blanks 30 with their respective axis of symmetry 30b at right angles to the top and bottom Longitudinal edge 31a, 31b are aligned, obliquely to Circumferential plane E of the transfer drum 33 tangentially at its Arrange the outer surface so that the leading Label edge 30a parallel to the longitudinal extension or Lead axis of the vacuum slide 34 and fed is donated.

Der mit a bezeichnete Anstellwinkel der Etikettenbandlaufrichtung L hängt ebenso wie die Konizität der Transfertrommel 33 von der Konizität der zu etikettierenden Becher 2 ab, da diese auch den Winkel der vorlaufenden Etikettenkante 30a eines einen oberen und unteren gekrümmten Etikettenrand aufweisenden Rundumetiketts 30 bezüglich der Laufrichtung L des Trägerbandes 31 bestimmt. Beim Übergang der vorlaufenden Etikettenkante 30a auf eine Vakuumleiste 34 liegt die Etikettenkante 30a in einer mit der Drehachse 35 der Transfertrommel 33 gemeinsamen, sich um die Drehachse 35 drehenden Ebene und verbleibt in dieser bis zum Ankleben der Etikettenkante 30a am Becher 2.The angle of attack marked with a Label tape running direction L depends as well as the taper the transfer drum 33 from the taper of the labeling cup 2, since this also the angle of leading label edge 30a of an upper and lower all-round label with curved label edge 30 determined with respect to the running direction L of the carrier tape 31. When the leading label edge 30a changes to a Vacuum strip 34 is the label edge 30a in one with the Axis of rotation 35 of the transfer drum 33 common, around the Axis of rotation 35 rotating plane and remains in this until Glue the label edge 30a to the cup 2.

Die Steuerkurve 38 der Vakuumschieber 34 ist so ausgebildet, dass ein Vakuumschieber 34 beim Passieren der Spendekante 32 während dem vollständigen Abspenden eines Etiketts 30 in Richtung S von oben nach unten quer zur Drehebene E in der Mantelfläche entlang einer Mantellinie der Transfertrommel so verfahren wird, dass zwischen dem abgespendeten Etikett 30 und dem zugeordneten Vakuumschieber Gleichlauf herrscht, d.h.keine die Lage bzw. Ausrichtung des Etiketts auf der Transfertrommel beeinflussende Relativbewegung vorhanden ist. Bei der Übergabe des Etiketts auf einen Becher erfolgt keine Bewegung der Vakuumschieber relativ zur Transfertrommel. Danach werden die Vakuumschieber vor Erreichen der Spendekante wieder nach oben in ihre Ausgangsstellung zurückgeschoben.The control curve 38 of the vacuum slide 34 is designed that a vacuum slide 34 when passing the dispensing edge 32 during the complete dispensing of a label 30 in Direction S from top to bottom across the plane of rotation E in the Lateral surface along a surface line of the transfer drum see above the procedure is that between the dispensed label 30 and the assigned vacuum slide is synchronized, i.e. no position or orientation of the label on the Relative movement influencing the transfer drum is present. When the label is handed over to a mug, there is no Movement of the vacuum slide relative to the transfer drum. After that, the vacuum gate valves are reached before Dispensing edge back up to its starting position pushed back.

Bei einer Umstellung der Etikettiermaschine auf einen Gegenstand mit einer anderen Konizität wird nicht nur die Transfertrommel ausgetauscht und der Anstellwinkel der Spendekante bzw. der Etikettenbandlaufrichtung verstellt, sondern auch die Steuerung für die Querbewegung der Vakuumschieber.When changing the labeling machine to one An object with a different conicity is not only the Transfer drum replaced and the angle of attack of the Dispensing edge or the label tape running direction adjusted, but also the control for the transverse movement of the Vacuum gate valve.

Bei der in Fig. 4 gezeigten Ausführung ist nicht nur das zur Spendekante zulaufende Etikettenband zur Umlaufebene E geneigt, sondern auch die Spendekante 32 ist um den Winkel α zur Längserstreckung bzw. Führungsachse der Vakuumschieber 34 geneigt. Diese Lösung ermöglicht eine zum zulaufenden Etikettenband 31 parallele Rückführung des etikettenfreien Trägerbandes 31' zu einer Aufwickelspule. Wegen der besseren Übersicht sind das Trägerband 31, 31' und die Spendekante 32 in der Fig. 4 nur mit gestrichelten Linien dargestellt.Die Spendekante könnte auch parallel zu den Vakuumschiebern und der vorlaufenden Etikettenkante 30a ausgerichtet werden, wobei die Spendekance dann bezüglich der Etikettenbandlaufrichtung L schiefwinklig positioniert wäre.In the embodiment shown in Fig. 4, not only that Dispensing edge tapering label tape to circulation level E inclined, but also the dispensing edge 32 is at the angle α for the longitudinal extension or guide axis of the vacuum slide 34 inclined. This solution enables one to run up Label tape 31 parallel return of the label-free Carrier tape 31 'to a take-up reel. Because of the better Overview is the carrier tape 31, 31 'and the dispensing edge 32 4 only shown with dashed lines Dispensing edge could also be parallel to the vacuum slides and the leading label edge 30a are aligned, the donation chance then with regard to the Label tape running direction L would be positioned at an oblique angle.
