Description

Die Erfindung betrifft einen Wendewickler einer Gießfolienanlage, umfassend einen Rahmen, in dem Wickelvorrichtungen für das Aufwickeln von Folie angeordnet sind, wobei mindestens drei Wickelvorrichtungen im Rahmen angeordnet sind, wobei zwei Wickelvorrichtungen auf einem ersten Höhenniveau und eine dritte Wickelvorrichtung auf einem zweiten, vom ersten Höhenniveau unterschiedlichen Höhenniveau angeordnet ist, wobei jede Wickelvorrichtung mindestens zwei Wickelwellen zum Aufwickeln von Folie aufweist und wobei die mindestens zwei Wickelwellen in einem Wendekreuz gelagert sind.The invention relates to a turret winder of a cast film plant, comprising a frame in which winding devices for winding film are arranged, wherein at least three winding devices are arranged in the frame, wherein two winding devices at a first height level and a third winding device at a second, from the first height level is arranged at different levels of height, each winding device has at least two winding shafts for winding foil and wherein the at least two winding shafts are mounted in a turning cross.

Wendewickler dieser Art sind beispielsweise aus der DE 32 39 661 A1 bekannt. Hier sind mehrere Wickelvorrichtungen auf verschiedenen Höhenniveaus angeordnet. Eine ähnliche Lösung zeigt die FR 1 120 135 A . Mit dem Aufwickeln von bandförmigem Gut zu Bobinen beschäftigen sich auch die US 6 283 401 B1 , die US 5 909 856 und die EP 2 067 724 A1 . Dokument US 5 941 474 zeigt auch eine Wickelvorrichtung mit vertikal verschwenkbaren Wickelwellen.Turret winder of this kind are for example from the DE 32 39 661 A1 known. Here several winding devices are arranged at different height levels. A similar solution shows the FR 1 120 135 A , The winding of tape-shaped good to reels also deal with the US Pat. No. 6,283,401 B1 that US 5,909,856 and the EP 2 067 724 A1 , document US 5,941,474 also shows a winding device with vertically pivotable winding shafts.

Wendewickler einer Gießfolienanlage, umfassend einen Rahmen, in dem Wickelvorrichtungen für das Aufwickeln von Folie angeordnet sind.Turret winder of a cast film plant, comprising a frame in which winding devices for the winding of film are arranged.

Eine Gießfolienanlage zur Herstellung von Folien weist im wesentlichen eine Extrudereinheit auf, in der Kunststoffmaterial plastifiziert wird. Der Extrudereinheit schließt sich die Gießstation an, in der aus der Kunststoffschmelze die Folie geformt wird. Hinter der Gießstation ist zumeist eine Einrichtung zur Messung der Dicke der gegossenen Folie angeordnet. Hinter einer sog. Corona-Einheit folgt dann besagter Wendewickler, in dem die Folie aufgewickelt und für die weitere Handhabung vorbereitet wird. Hier ist insbesondere an ein Wenden der Folie gedacht, um verschiedene Folienlagen zu konfigurieren und bereitzustellen.A cast film plant for producing films essentially has an extruder unit in which plastic material is plasticized. The extruder unit is followed by the casting station in which the film is formed from the plastic melt. A device for measuring the thickness of the cast film is usually arranged behind the casting station. Behind a so-called corona unit then follows said turret winder, in which the film is wound and prepared for further handling. Here, in particular, a turning of the film is intended to configure and provide various film layers.

Die genannte Anlage kann beispielsweise als sog. Stretchfolienanlage ausgebildet sein, wobei dann auf ihr beispielsweise die Herstellung sog. Palettenstretchfolie erfolgen kann.The abovementioned installation can be designed, for example, as a so-called stretch film installation, in which case, for example, the production of so-called pallet stretch film can take place.

Derartige Anlagen können für eine gewisse Folienbreite konzipiert werden (z. B. 4 x 500 mm Nettofolienbreite als sog. 4-up-Ausführung oder 8 x 500 mm Nettofolienbreite als sog. 8-up-Ausführung).Such systems can be designed for a certain film width (eg 4 x 500 mm net film width as a so-called 4-up version or 8 x 500 mm net film width as a so-called 8-up version).

Zu beachten ist bei den in Rede stehenden Wendewicklern, dass sie aufgrund der zu verarbeitenden Größe (maximal 450 mm Durchmesser bei Stretchfolienwicklern) eine gewisse kritische Durchbiegung erreichen, bei der die Welle bruchgefährdet ist und die Rotation der Wickelwelle instabil wird und dementsprechend ein unbefriedigendes Wickelergebnis vorliegt. Daher werden Wickler (Wickelvorrichtungen) im allgemeinen nur bis zu einer gewissen Folienbreite gebaut. Bekannt geworden ist es auch, für den Fall breiterer Lösung zwei nebeneinander angeordnete Wickler im Wendewickler anzuordnen.It should be noted in the present Wendewicklern that they reach a certain critical deflection due to the size to be processed (maximum 450 mm diameter in stretch film winder), in which the shaft is at risk of breakage and the rotation of the winding shaft is unstable and accordingly there is an unsatisfactory winding result , Therefore, winders (winders) are generally built only up to a certain film width. It has also become known to arrange two juxtaposed winder in the turret winder for the case of a wider solution.

Nachteilig ist, dass eine beliebige Aufteilung der Folie auf mehrere Wickler zu Platzproblemen führen kann, insbesondere was die Bestückung der Wickelwelle mit (Wickel)Hülsen und die Entnahme der fertig gewickelten Bobinen anbelangt.The disadvantage is that any division of the film on several winder can lead to space problems, in particular as regards the placement of the winding shaft with (winding) sleeves and the removal of the finished wound bobbins.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Wendewickler der eingangs genannten Art so fortzubilden, dass auch größere Anlagen problemlos ausgeführt werden können, wobei zum einen darauf Wert gelegt wird, dass eine einwandfreie Wicklung hinreichend beabstandet von kritischen Wicklerdrehzahlen erfolgen kann und wobei zum anderen wesentlich ist, dass die erzeugte Folie vorteilhaft gehandhabt werden kann. Ein weiterer wichtiger Aspekt ist, dass der Platzbedarf für den Wendewickler möglichst gering sein soll, so dass eine entsprechend große Anlage ohne wesentliche Mehrkosten - was den Raumbedarf anbelangt - realisierbar ist. Dabei kommt der Entnahme fertiger Bobinen von den Wickelwellen und deren Bestückung mit Hülsen eine wesentliche Bedeutung zu; diesbezüglich soll eine platzsparende und gut automatisierbare Lösung vorgeschlagen werden, wodurch also eine platzsparende Bauweise und ein effizienter Betrieb ermöglicht werden soll.The invention is therefore based on the object , a turret winder of the type mentioned in such a way that even larger systems can be performed easily, on the one hand it is important that a proper winding can be sufficiently spaced from critical winder speeds and where on the other essential is that the film produced can be handled advantageously. Another important aspect is that the space required for the turret winder should be as low as possible, so that a correspondingly large system without significant additional costs - in terms of space requirements - is feasible. It is the removal of finished bobbins from the winding shafts and their placement with sleeves essential to; In this regard, a space-saving and easy to automate solution to be proposed, which is thus a space-saving design and efficient operation should be possible.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass die Wickelwellen im Wendekreuz um eine vertikal angeordnete Achse verschwenkbar angeordnet sind, wobei der Schwenkpunkt der Wickelwelle in einem axialen Endbereich der Wickelwelle angeordnet ist, wobei die Schwenkpunkte zweier Wickelwellen, die sich auf dem gleichen Höhenniveau befinden, in benachbarten axialen Endbereichen der Wickelwelle liegen.The solution of this problem by the invention is characterized in that the winding shafts are arranged pivotably about a vertically arranged axis in the turning cross, wherein the pivot point of the winding shaft is disposed in an axial end portion of the winding shaft, wherein the pivot points of two winding shafts, which are on the same Height level are located in adjacent axial end portions of the winding shaft.

Der maximale Schwenkwinkel beträgt dabei vorzugsweise 20°, besonders bevorzugt maximal 15°.The maximum pivot angle is preferably 20 °, more preferably a maximum of 15 °.

Zumindest eine Wickelwelle einer Wickelvorrichtung kann dabei auf dem ersten Höhenniveau und zumindest eine Wickelwelle einer Wickelvorrichtung auf dem zweiten Höhenniveau im selben Schwenksinn und parallel zueinander um die vertikal angeordnete Achse verschwenkbar angeordnet sein. Damit kann erreicht werden, dass die gewickelten Rollen (Bobinen) parallel von zwei Wickelwellen gleichzeitig abgezogen werden können. Hierdurch ist eine sehr platzsparende Anordnung möglich, die eine überlappende Konstruktion nutzt.At least one winding shaft of a winding device can be arranged pivotably on the first height level and at least one winding shaft of a winding device on the second height level in the same pivoting and parallel to each other about the vertically arranged axis. It can thus be achieved that the wound reels (bobbins) can be pulled off parallel from two winding shafts at the same time. As a result, a very space-saving arrangement is possible, which uses an overlapping construction.

Der Wendewickler hat vorzugsweise weiterhin mindestens einen Entnahmewagen für gewickelte Folie, wobei der Entnahmewagen auf einem sich zumindest abschnittsweise geradlinig erstreckenden Schienensystem translatorisch beweglich ist, wobei die Richtung des Schienensystems unter dem maximalen Schwenkwinkel zum Rahmen ausgerichtet ist.The turret winder preferably further has at least one taken-out trolley for wound film, wherein the pick-up trolley is translationally movable on a rail system extending at least in sections, wherein the direction of the rail system is aligned with the frame at the maximum pivoting angle.

Das erste Höhenniveau ist vorzugsweise niedriger als das zweite Höhenniveau.The first height level is preferably lower than the second height level.

Eine bevorzugte Weiterbildung sieht vor, dass zwei sich auf dem ersten Höhenniveau befindliche Wickelvorrichtungen an zwei seitlichen Endbereichen des Rahmens angrenzen und die benachbarten axialen Endbereiche der Wickelwellen in der Maschinenmitte liegen. Vorzugsweise ist dabei eine sich auf dem zweiten Höhenniveau befindliche Wickelvorrichtung zwischen den beiden seitlichen Endbereichen des Rahmens zentrisch angeordnet. Die axiale Erstreckung der sich auf dem zweiten Höhenniveau befindlichen Wickelvorrichtung kann weiterhin mit den axialen Erstreckungen der beiden sich auf dem ersten Höhenniveau befindlichen Wickelvorrichtungen überlappen; hierbei kann die Überlappung zwischen 5 % und 50 % der axialen Erstreckung einer der Wickelvorrichtungen betragen. Jede Wickelvorrichtung hat dabei bevorzugt die gleiche axiale Länge.A preferred embodiment provides that two winding devices located at the first height level adjoin two lateral end regions of the frame and the adjacent axial end regions of the winding shafts are located in the machine center. Preferably, a winding device located at the second height level is arranged centrally between the two lateral end regions of the frame. The axial extent of the located on the second level height winding device can continue with the axial extensions of the two located at the first level height winders overlap; In this case, the overlap between 5% and 50% of the axial extent of one of the winding devices amount. Each winding device preferably has the same axial length.

Die sich auf dem ersten Höhenniveau befindlichen Wickelvorrichtungen und eine sich auf dem zweiten Höhenniveau befindliche Wickelvorrichtung können in Richtung radial zur Drehachse der Wickelvorrichtungen und in Richtung der Horizontalen versetzt zueinander angeordnet sein.The winding devices located at the first height level and a winding device located at the second height level can be arranged offset in the direction radially to the axis of rotation of the winding devices and in the direction of the horizontal.

Jede der Wickelvorrichtungen kann dabei ausgelegt sein, um Folien bis zu einem Wickeldurchmesser von 600 mm aufzuwickeln.Each of the winding devices can be designed to wind up to a winding diameter of 600 mm foils.

Jeder Wickelvorrichtung kann eine Messrolle zur Bestimmung der Spannung in der aufzuwickelnden Folie zugeordnet sein.Each winding device may be associated with a measuring roller for determining the tension in the film to be wound.

Ferner kann jede Wickelvorrichtung mit einem Regelsystem zur Reduzierung oder Verhinderung von Schwingungen ausgestattet sein, um die kritische Drehzahl der Wickelvorrichtung verändern oder eliminieren zu können.Furthermore, each winding device can be equipped with a control system for reducing or preventing vibrations in order to be able to change or eliminate the critical speed of the winding device.

Der Rahmen hat bevorzugt zwei seitliche Wangen, die über Holme miteinander verbunden sind.The frame preferably has two lateral cheeks which are connected to each other via bars.

Alle Wickelvorrichtungen können einer gemeinsamen Schneidvorrichtung zugeordnet sein, die zum Längstrennen der Folienbahn ausgebildet ist.All winding devices may be associated with a common cutting device, which is designed for longitudinal separation of the film web.

Der Wendewickler ist gemäß einer bevorzugten Ausgestaltung der Erfindung Bestandteil einer Stretchfolienanlage.The turret winder is according to a preferred embodiment of the invention part of a stretch film plant.

Die vorgeschlagene Lösung macht es möglich, auch größere Anlagen (ausgeführt beispielsweise als sog. 12-up-Anlagen) zu realisieren, wobei das Wickeln der Folie im Wendewickler problemlos möglich ist.The proposed solution makes it possible to realize even larger systems (executed, for example, as so-called. 12-up systems), the winding of the film in the turret winder is easily possible.

Der vorgeschlagene Wendewickler erlaubt eine ausreichende Wickelgeschwindigkeit der Folie, wobei hinreichender Abstand von der oder den kritischen Wellendrehzahlen gehalten werden kann, so dass ein sauberes Aufwickeln sichergestellt ist.The proposed turret winder allows a sufficient winding speed of the film, with a sufficient distance from the critical shaft speeds or the rotational speeds can be maintained, so that a clean winding is ensured.

Weiterhin ist der Platzbedarf für den Wendewickler optimiert, da die genannten Anordnung der bevorzugt insgesamt drei Wickler (Wickelvorrichtungen) optimal im Rahmen erfolgt, so dass bei gegebener Stellfläche des Wendewicklers eine höchstmögliche Leistungsfähigkeit des Wicklers gegeben ist. Die Raumkosten werden so gering gehalten. Die gilt insbesondere unter Berücksichtigung der Entnahme fertig gewickelter Bobinen und der Bestückung der Wickelwellen mit Hülsen für das Aufwickeln von Folie. Die genannte Verschwenkbarkeit der Wickelwellen um eine Vertikalachse erlaubt bei der genannten Anordnung eine sehr kompakte Bauweise bei geringem Platzbedarf.Furthermore, the space required for the turret winder is optimized, since the said arrangement of preferably three winder (winder) optimally takes place in the frame, so that given the footprint of the turret winder a maximum performance of the winder is given. The room costs are kept so low. This applies in particular taking into account the removal of finished wound bobbins and the loading of the winding shafts with sleeves for the winding of film. The said pivoting of the winding shafts about a vertical axis allows in the said arrangement a very compact design with a small footprint.

In Fig. 1 ist ein Wendewickler 1 zu sehen, der Bestandteil einer Stretchfolienanlage ist. Der Wendewickler weist einen Rahmen 2 auf, dessen Hauptkomponenten zwei Wangen 8 und 9 sind, die über Holme 10 miteinander verbunden sind und auf definiertem Abstand gehalten werden.In Fig. 1 is to see a turret winder 1, which is part of a stretch film plant. The turret winder has a frame 2, the main components of which are two cheeks 8 and 9, which are connected to one another via bars 10 and are held at a defined distance.

Im Rahmen 2 sind insgesamt drei Wickelvorrichtungen 3, 4 und 5 gelagert, auf denen jeweils Folie aufgewickelt werden kann.In frame 2, a total of three winding devices 3, 4 and 5 are stored, on each of which film can be wound.

Jede Wickelvorrichtung 3, 4, 5 umfasst dabei mindestens zwei (dargestellt im Ausführungsbeispiel, gegebenenfalls auch drei oder vier) Wickelpositionen mit jeweiligen Wickelwellen 11, die in Wendekreuzen 12 drehbar angeordnet sind. Hierbei werden die freie Wickellänge verkürzt und die Wickelqualität beim Wenden erhöht. Dies ist im Stand der Technik allerdings bekannt, so dass Details hierzu nicht beschrieben werden müssen (s. den oben genannten Stand der Technik).Each winding device 3, 4, 5 comprises at least two (shown in the embodiment, optionally also three or four) winding positions with respective winding shafts 11 which are rotatably arranged in turning crosses 12. Hereby the free winding length is shortened and the winding quality is increased during turning. However, this is known in the prior art, so that details for this need not be described (see the above-mentioned prior art).

Dabei ist zu erkennen, dass die beiden unteren Wickelvorrichtungen 3 und 4 auf einem ersten unteren, d. h. niedrigerem Höhenniveau H1 angeordnet sind, während die dritte Wickelvorrichtung 5 auf einem höheren zweiten Höhenniveau H2 angeordnet ist. Demgemäß sind die beiden Wickelvorrichtungen 3 und 4 in Richtung der Vertikalen V tiefer im Rahmen angeordnet als die Wickelvorrichtung 5.It can be seen that the two lower winding devices 3 and 4 are arranged on a first lower, ie lower height level H 1 , while the third winding device 5 is arranged at a higher second height level H 2 . Accordingly, the two winding devices 3 and 4 in the direction of the vertical V are arranged deeper in the frame than the winding device. 5

Aber auch in Richtung der Horizontalen H, und zwar in radiale Richtung auf die Drehachsen der Wickelvorrichtungen 3, 4, 5 betrachtet, ist die Wickelvorrichtung 5 zu den Vorrichtungen 3 und 4 versetzt angeordnet im Rahmen 2 gelagert.But also in the direction of the horizontal H, and viewed in the radial direction on the axes of rotation of the winding devices 3, 4, 5, the winding device 5 is arranged offset to the devices 3 and 4 arranged in the frame 2.

Mit Blick auf die Anordnung der beiden unteren Wickelvorrichtungen 3, 4 im Rahmen 2 ist ferner zu sehen, dass diese beiden Vorrichtungen an die seitlichen Endbereiche 6 bzw. 7 angrenzen, während die obere Wickelvorrichtung 5 zentrisch zwischen den Endbereichen 6, 7, d. h. zentrisch zwischen den Wangen 8 und 9 angeordnet ist.With regard to the arrangement of the two lower winding devices 3, 4 in the frame 2 is further seen that these two devices adjacent to the side end portions 6 and 7, while the upper winding device 5 centrally between the end portions 6, 7, d. H. is arranged centrally between the cheeks 8 and 9.

Allerdings liegt eine Überlappung x - gesehen in axiale Richtung der Wickelvorrichtungen - zwischen der Wickelvorrichtung 3 und der Wickelvorrichtung 5 vor. Analoges gilt für die Wickelvorrichtungen 4 und 5.However, there is an overlap x - seen in the axial direction of the winding devices - between the winding device 3 and the winding device 5. The same applies to the winding devices 4 and 5.

Wesentlich ist, dass die Wickelwellen 11 im Wendekreuz 12 um eine vertikal angeordnete Achse A verschwenkbar angeordnet sind, wobei der Schwenkpunkt S der Wickelwelle 11 in einem axialen Endbereich 13 bzw. 14 der Wickelwelle 11 angeordnet ist. Die Schwenkpunkte S zweier Wickelwellen 11, die sich auf dem gleichen Höhenniveau H1 befinden, liegen dabei in benachbarten axialen Endbereichen 13 bzw. 14 der Wickelwelle 11.It is essential that the winding shafts 11 in the turning cross 12 are arranged pivotable about a vertically arranged axis A, wherein the pivot point S of the winding shaft 11 in an axial end portion 13 and 14 of the winding shaft 11 is arranged. The pivot points S of two winding shafts 11, which are located at the same height level H 1 , lie in adjacent axial end regions 13 and 14 of the winding shaft 11.

Wie es am besten in Fig. 2 und Fig. 3 gesehen werden kann, können demgemäß die Wickelwellen 11 zwecks Entnahme von Bobinen 17 (und zum Aufschieben von Hülsen 18) um einen Schwenkwinkel α um die vertikal ausgerichtete Achse A verschwenkt werden. Wie es sich für die beiden herausgeschwenkten Wickelwellen 11 der Wickelvorrichtungen 3 und 5 ergibt (s. insbesondere Fig. 3), können demgemäß die Wickelwellen 11 parallel zueinander ausgeschwenkt werden, so dass eine besonders platzsparende und simultane Entnahme der Bobinen 17 möglich ist.As it is best in Fig. 2 and Fig. 3 can be seen, therefore, the winding shafts 11 for the purpose of removing bobbins 17 (and for pushing sleeves 18) by a pivot angle α about the vertically oriented axis A can be pivoted. As it turns out for the two swung-out winding shafts 11 of the winding devices 3 and 5 (see, in particular Fig. 3 ), Accordingly, the winding shafts 11 can be swung out parallel to each other, so that a particularly space-saving and simultaneous removal of the bobbins 17 is possible.

Dies ergibt sich bei Ausstattung des Wendewicklers 1 mit drei Wickelvorrichtungen 3, 4 und 5 insbesondere dann, wenn zwei sich auf dem ersten Höhenniveau H1 befindliche Wickelvorrichtungen 3 und 4 an den beiden seitlichen Endbereichen 6 und 7 des Rahmens 2 angrenzen und die benachbarten axialen Endbereiche 13 und 14 der Wickelwellen 11 in der Maschinenmitte M liegen (s. Fig. 3).This results in the equipment of the turret winder 1 with three winding devices 3, 4 and 5 in particular when two winding devices 3 and 4 located at the first height level H 1 at the adjacent to both side end portions 6 and 7 of the frame 2 and the adjacent axial end portions 13 and 14 of the winding shafts 11 in the machine center M are (s. Fig. 3 ).

Die Entnahme fertig gewickelter Bobinen 17 und das Aufschieben von Hülsen 18 zum Aufwickeln des bandförmigen Materials erfolgt automatisch mittels einer Anzahl Entnahmewagen 15, die auf einem Schienensystem 16 verfahrbar sind.The removal of finished wound bobbins 17 and the pushing of sleeves 18 for winding the band-shaped material takes place automatically by means of a number of picking trolleys 15 which are movable on a rail system 16.

In den Figuren 4 bis 8 sind hierzu in der zeitlichen Abfolge verschiedene Verfahrensstadien skizziert.In the FIGS. 4 to 8 For this purpose, different stages of the process are outlined in chronological order.

Gemäß Fig. 4 befinden sich die Entnahmewagen 15 in der Warteposition. Zu sehen ist, dass auf den hinten angeordneten Wickelwellen 11' gerade noch Folie aufgewickelt wird, während auf den vorne angeordneten Wickelwellen 11" die Hülsen 18 für die nächste Wicklung aufgeschoben sind.According to Fig. 4 are the removal car 15 in the waiting position. It can be seen that on the winding shafts 11 'arranged at the rear, film is just being wound up, while on the winding shafts 11 "arranged at the front, the sleeves 18 for the next winding are pushed on.

Wie in Fig. 5 zu sehen, sind die Wickelwellen 11 nun durch die Wendekreuze gewendet worden, so dass die fertigen Bobinen 17 vorne zu liegen kommen und entnommen werden können. Hierzu sind die Wickelwellen 11 um die Achsen A aus dem Wendewickler herausgeschwenkt worden. Die Entnahmewagen 15 wurde vorher in Position gefahren und können die Bobinen 17 aufnehmen.As in Fig. 5 can be seen, the winding shafts 11 have now been turned by the turning crosses, so that the finished bobbins 17 come to lie in front and can be removed. For this purpose, the winding shafts 11 have been swung out about the axes A from the turret winder. The trolley 15 was previously moved into position and can accommodate the reels 17.

Der Abziehvorgang der Bobinen 17 von den Wickelwellen 11 ist in Fig. 6 illustriert. In Fig. 7 ist zu sehen, wie die Bobinen 17 alle abgezogen sind; es werden jetzt Hülsen 18 auf die leeren Wickelwellen aufgeschoben. Dieser Vorgang ist gemäß Fig. 8 abgeschlossen, d. h. die Hülsen 18 befinden sich auf den Wickelwellen, die als nächstes wieder eingeschwenkt werden.The peeling operation of the reels 17 of the winding shafts 11 is in Fig. 6 illustrated. In Fig. 7 you can see how the bobbins 17 are all taken off; now sleeves 18 are pushed onto the empty winding shafts. This process is according to Fig. 8 completed, ie the sleeves 18 are located on the winding shafts, which are next swung back.

Nachdem die im Wendewickler hinten gewickelten Bobinen 17 fertig gewickelt sind, erfolgt ein Wenden per Wendekreuz 12, so dass die auf die Wickelwellen 11 aufgefädelten Hülsen 18 in die Position zum Aufwickeln von Folie gebracht werden.After the wound in the turret winder reels 17 are finished wound, turning takes place by turning cross 12, so that the threaded on the winding shafts 11 sleeves 18 are brought into the position for winding of foil.

Der beschriebene Vorgang erfolgt aufs Neue.The process described is done again.
