Definitions
- the invention relates to a support roller winding machine for winding material webs, in particular paper or cardboard webs, on sleeves according to the preamble of claim 1.
- Such winding machines are used to produce winding rolls from the material webs divided by longitudinal section. When winding, the winding rolls lie axially aligned on the two support rollers.
- WO 92/03366 a generic carrier roller winding machine is known, in which an overpressure is generated by means of compressed air in the space delimited by the carrier rollers and the winding rollers.
- the air box can be swung down from an upper working position, in which its side surfaces lie sealingly against the support rollers, into a position below a support roller.
- the swiveling down creates space for a separate separating knife, which can be raised from below through the support roller nip, on the tear-off blade of which the web tears off when the full winding rolls are ejected.
- the invention has for its object to improve a generic support roller winding machine so that a roll change can be carried out in a shorter time with a space-saving design.
- the arrangement of the cutting knife support with the tear-off blade in the air box takes up less space than a separate cutting knife.
- the air box does not need to be lowered for a roll change. Lowering is only necessary to insert a new web or in the event of a paper jam.
- the roll change can be carried out more quickly, since the tear-off blade of the separating knife can be moved up into its separating position in the roller bed without first swiveling the air box away.
- the carrier roller winding machine has two driven carrier rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers 4 rest on the carrier rollers 1, 2 during winding.
- the material web 5, which is subdivided in the longitudinal direction into individual webs - preferably a paper or cardboard web - is deflected by the support roller 1 from below through the gap between the support rollers 1, 2 into the support roller bed 3 and wound there on sleeves 6 aligned.
- the completely wound winding rolls 4 are pressed by an ejection bar, not shown, over the support roller 2 onto a lowering platform 7, from which the winding rolls 4 are lowered for unloading.
- an excess pressure can be generated with compressed air in the space delimited by the support rollers 1, 2 and the winding rollers 6.
- an air box 8 with a compressed air supply is in the lower gusset between the two support rollers 1, 2 9 arranged, which extends over the axial length of the support rollers 1, 2 and the side surfaces facing the support rollers 1, 2 are curved in the upper part adapted to the lateral surfaces of the support rollers 1, 2, so that they can seal against them.
- a plurality of axially extending felt strips are inserted on the outside, which seal the air box 8 against the support rollers 2 with minimal friction.
- the air box 8 is attached to swivel arms 10 which are mounted in the frame of the machine. It can thus be lowered from its upper sealing position to a rest position - shown in broken lines in FIG. 1 - for example in order to introduce a new web 5. In the upper sealing position, its upper part extends to the narrowest point between the two support rollers 1, 2.
- the upper boundary surface facing the support roller gap has an air outlet slot 11 which extends at least over the minimum web width and is on both machine sides as a guide surface for two End-side sealing elements 12 arranged on both sides of the machine are formed.
- the shape of the end sealing elements 12 is adapted to the free cross-sectional area between the support rollers 1, 2, its upper part being elongated in a rectangular shape up to above the connecting line between the two vertices of the support rollers 1, 2, in order to provide a sufficient sealing surface for winding rollers 4 with a large diameter to back up. They are slidably mounted in the axial direction - that is to say transversely to the path 5 - on lateral pivot arms 13, the pivot axis of which runs somewhat eccentrically offset to the outside on the connecting line between the two carrier roller axes.
- the sealing elements 12 can thus be pivoted out of the roller bed 3 over the support roller 2 into a position in which the lateral guide heads can be moved into the sleeves 6.
- the low eccentricity means that the side surfaces of the sealing elements 12 facing the support rollers 1, 2 move somewhat away from the respective support roller surface when swiveling out, for example in order to be able to remove paper residues.
- a separating knife 14 is arranged with a tear-off blade 15 which, in the sealing position of the air box 8, can be moved up into the roller bed 3 and lowered into the air box 8.
- the tear-off blade 15 is lowered in FIG. 2, and in FIG. 3 it is in its separation position in the roller bed 3.
- the tear-off blade 15 extends over the entire length of the feed slot 15, that is to say essentially over the entire machine width. It is attached to the end of a likewise machine-wide holder 16 in the form of a two-sided lever, which is articulated approximately in the middle at the end of a vertical support 18 about an axis 17 parallel to the support roller axes.
- the support 18 is attached to the end of the piston rods 19 by vertical, hydraulic piston-cylinder units, the cylinders 20 of which are screwed onto the bottom of the air box 8 and are thus supported on the latter.
- the cylinders 21 are fastened by pneumatic piston-cylinder units, the piston rods 22 of which extend vertically upwards.
- the end of the piston rods 22 is connected in an articulated manner to the holder via lever 23 in such a way that the articulation points 24 with the holder 16, when the piston rods 22 are completely retracted, are somewhat offset relative to the articulation points 25 with the piston rods 22 in the direction of the supporting roller 2.
- the tear-off blade 15 is clearly moved in the direction of the supporting roller 1 when the piston rods 22 are extended, as shown in FIG. 3. So that the holder 16 and the levers 23 can be stretched, the support 18 has cutouts in its upper part, into which these can be moved.
- the end of the lever 16 facing away from the tear-off blade 15 consists of individual, spaced-apart tabs, one of the levers 23 being articulated alternately at the end of the respective tabs or a freely rotatable wheel 26 being mounted.
- the axis of rotation of the freely rotatable wheels 26 extends coaxially to the articulation points 24.
- There are also recesses in the support 18 for the wheels 26 thus offset in the axial direction from the levers 23, into which they can be moved.
- the lower part of the support 18 with the piston-cylinder units 21, 22 is guided on vertical guides 27 which are arranged in the upper part of the air box 8.
- the entire cutting knife with its lifting mechanism is arranged in the air box 8. It is also possible to attach the cylinder 20 of the piston-cylinder unit 19, 20 to the outside on the underside of the air box 8 and to guide the piston rod 19 in a sealed manner through the bottom of the air box 8. This has the advantage that the supply lines for the piston-cylinder units 19, 20 can be arranged outside the air box 8. If it is necessary for the stability of the air box 8 to arrange vertical transverse bulkheads in it, the separating knife 14 can be divided into individual (e.g. four at 8 m working width) segments which are successively arranged in the axial direction.
- Each of these segments then consists of the parts which extend continuously across the segment width (tear-off blade 15, holder 16, support 18), which are moved up and down by two lateral piston-cylinder units 19, 20 and in which the tilting movement of the tear-off blade 15 is effected by 2 lateral piston-cylinder units 21, 22 fastened to the lower part of the support 8.
- the end sealing elements 12 are pivoted into the roll bed 3 and moved axially against the end faces of the winding rolls 4.
- the air box 8 is pivoted upward, so that the lower gusset between the support rollers 1, 2 is sealed and the sealing elements 12 can be placed on its upper boundary surface. They seal the air outlet slot 11 outside the winding roll area.
- the compressed air supply is switched off, the end sealing elements 12 are pivoted out of the roller bed 3 and the tear-off blade 15 of the cutting knife 14 is moved into the cutting position shown in FIG. 3.
- compressed air is first introduced into the cylinders 21 initiated and so the piston 22 biased.
- a tilting movement of the holder 16 is not yet possible since a lateral movement of the wheels 26 in the direction of the support roller 2 is prevented by the guide rails.
- the piston-cylinder units 19, 20 move the tear-off blade 15 upwards. As soon as the wheels 26 have left the air box 8 at the top, they are guided by the support roller 2.
- the tear-off blade 15 when the tear-off blade 15 is moved upward, a tilting movement takes place in the direction of the supporting roller 1 without the piston-cylinder units 21, 22 having to be controlled.
- the height of the support 18, the width of the holder 16 and the stroke of the pistons 22 are selected so that the tear-off blade 15 moves exactly into its separation position in the roller bed 3 with a short distance from the wrapped support roller 1 when the piston rods 19 are raised.
- the full winding rolls 4 are then ejected via the non-looped support roller 2, the web 5 tearing off on the tear-off blade 15.
- the new web start created in this way is held on the support roller 1, for example sucked onto it with a vacuum.
- the tear-off blade 15 is then sunk again into the air box 8.
- the piston-cylinder units 19, 20 move the support 18 with all the parts attached to it until the tear-off blade 15 is in the air box 8 is located.
- the support rollers 1, 2 are rotated again and the winding is started again.

Abstract
Description
Die Erfindung betrifft eine Tragwalzen-Wickelmaschine zum Aufwickeln von Materialbahnen, insbesondere Papier- oder Kartonbahnen, auf Hülsen gemäß dem Oberbegriff des Patentanspruchs 1. Derartige Wickelmaschinen dienen zur Herstellung von Wickelrollen aus der durch Längsschnitt unterteilten Materialbahnen. Die Wickelrollen liegen beim Aufwickeln axial fluchtend auf den beiden Tragwalzen.The invention relates to a support roller winding machine for winding material webs, in particular paper or cardboard webs, on sleeves according to the preamble of claim 1. Such winding machines are used to produce winding rolls from the material webs divided by longitudinal section. When winding, the winding rolls lie axially aligned on the two support rollers.
Um die durch einen Wickelrollenwechsel bedingten Maschinenstillstandszeiten möglichst gering zu halten, ist es aus der DE-OS 2920707 bekannt, die Materialbahn in dem von den Tragwalzen gebildeten Walzenbett mittels einer durch den Tragwalzenspalt hochfahrbaren Trenneinrichtung mit einer Abreißklinge beim Ausstoßen der vollen Wickelrollen durchzutrennen. Der beim Durchtrennen neu geschaffene Bahnanfang wird durch Unterdruck auf der umschlungenen Tragwalze festgehalten, bis ein Satz neuer Hülsen in das Walzenbett eingelegt ist.In order to keep the machine downtimes caused by changing the winding reels as short as possible, it is known from DE-OS 2920707 to sever the material web in the roller bed formed by the supporting rollers by means of a separating device which can be raised by the supporting roller gap with a tear-off blade when the full winding reels are ejected. The newly created path start is cut by negative pressure on the wrapped roller until a set of new sleeves is inserted into the roller bed.
Aus der WO 92/03366 ist eine gattungsgemäße Tragwalzen-Wickelmaschine bekannt, bei der in dem von den Tragwalzen und den Wickelrollen begrenzten Raum mittels Druckluft ein Überdruck erzeugt wird. Der Überdruck verringert das Auflagegewicht und somit die Linienlast (= Auflagengewicht pro Breite einer Wickelrolle) an den beiden Auflagelinien der Wickelrollen auf den Tragwalzen, von der die Wickelhärte einer Wickelrolle entscheidend beeinflußt wird. Durch die Entlastung lassen sich Wickelrollen mit sehr großem Durchmesser (mehr als 800 mm) mit sehr guter Wickelqualtiät wickeln. Nach einer Ausführungsform ist im Bereich des unteren Zwickels zwischen den Tragwalzen ein Luftkasten angeordnet, der sich über die gesamte Arbeitsbreite (= axiale Länge der Tragwalzen) erstreckt und mit einer Druckluftzufuhr versehen ist. Der Luftkasten ist von einer oberen Arbeitsposition, in der seine Seitenflächen dichtend an den Tragwalzen anliegen bis in eine Position unterhalb einer Tragwalze niederschwenkbar. Das Niederschwenken schafft Platz für ein getrenntes, von unten durch den Tragwalzenspalt hochfahrbares Trennmesser, an dessen Abreißklinge die Bahn beim Ausstoßen der vollen Wickelrollen abreißt.From WO 92/03366 a generic carrier roller winding machine is known, in which an overpressure is generated by means of compressed air in the space delimited by the carrier rollers and the winding rollers. The overpressure reduces the support weight and thus the line load (= support weight per width of a winding roll) on the two contact lines of the winding rolls on the support rollers, which decisively influences the winding hardness of a winding roll. Due to the relief, winding rolls with a very large diameter (more than 800 mm) can be wound with very good winding quality. According to one embodiment, an air box is arranged in the area of the lower gusset between the support rollers and extends over the entire working width (= axial length of the support rollers) and is provided with a compressed air supply. The air box can be swung down from an upper working position, in which its side surfaces lie sealingly against the support rollers, into a position below a support roller. The swiveling down creates space for a separate separating knife, which can be raised from below through the support roller nip, on the tear-off blade of which the web tears off when the full winding rolls are ejected.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Tragwalzen-Wickelmaschine so zu verbessern, daß bei platzsparender Bauweise ein Rollenwechsel in kürzerer Zeit durchgeführt werden kann.The invention has for its object to improve a generic support roller winding machine so that a roll change can be carried out in a shorter time with a space-saving design.
Dieser Aufgabe wird mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the characterizing features of patent claim 1.
Die Anordnung der Trennmesserstütze mit der Abreißklinge in dem Luftkasten benötigt weniger Platz als ein getrenntes Trennmesser. Darüber hinaus braucht der Luftkasten für einen Rollenwechsel nicht abgesenkt zu werden. Ein Absenken ist nur zum Einführen einer neuen Bahn oder bei einem Papierstau erforderlich. Der Rollenwechsel läßt sich beschleunigt durchführen, da die Abreißklinge des Trennmessers ohne vorheriges Wegschwenken der Luftkastens in ihre Trennposition im Walzenbett hochbewegt werden kann.The arrangement of the cutting knife support with the tear-off blade in the air box takes up less space than a separate cutting knife. In addition, the air box does not need to be lowered for a roll change. Lowering is only necessary to insert a new web or in the event of a paper jam. The roll change can be carried out more quickly, since the tear-off blade of the separating knife can be moved up into its separating position in the roller bed without first swiveling the air box away.

Die Tragwalzen-Wickelmaschine weist zwei angetriebene Tragwalzen 1, 2 auf, zwischen denen ein Walzenbett 3 ausgebildet ist, in dem die Wickelrollen 4 während des Aufwickelns auf den Tragwalzen 1, 2 aufliegen. Die in Längsrichtung in Einzelbahnen unterteilte Materialbahn 5 - vorzugsweise eine Papier- oder Kartonbahn - wird von der Tragwalze 1 umgelenkt von unten durch den Spalt zwischen den Tragwalzen 1, 2 in das Tragwalzenbett 3 geführt und dort auf fluchtend aufgereihte Hülsen 6 aufgewickelt. Die fertiggewickelten Wickelrollen 4 werden von einem nicht dargestellten Ausstoßbalken über die Tragwalze 2 auf eine Absenkbühne 7 gedrückt, von der die Wickelrollen 4 zum Entladen abgesenkt werden.The carrier roller winding machine has two driven carrier rollers 1, 2, between which a
Zur Verminderung des Auflagegewichts der Wickelrollen 4 auf den Tragwalzen 1, 2 kann in den durch die Tragwalzen 1, 2 und die Wickelrollen 6 begrenzten Raum mit Druckluft ein Überdruck erzeugt werden. Dazu ist im unteren Zwickel zwischen den beiden Tragwalzen 1, 2 ein Luftkasten 8 mit einer Druckluftzufuhr 9 angeordnet, der sich über die axiale Länge der Tragwalzen 1, 2 erstreckt und dessen den Tragwalzen 1, 2 zugewandte Seitenflächen im oberen Teil den Mantelflächen der Tragwalzen 1, 2 angepaßt gekrümmt sind, damit sie sich dichtend an diese anlegen können. In die gekrümmten Seitenflächen sind mehrere axial sich erstreckende Filzstreifen außen eingelegt, die bei minimaler Reibung den Luftkasten 8 gegen die Tragwalzen 2 abdichten. Der Luftkasten 8 ist an Schwenkarmen 10 befestigt, die im Gestell der Maschine gelagert sind. Er kann so von seiner oberen Dichtposition bis in eine Ruheposition abgesenkt werden - in Fig. 1 strichpunktiert gezeichnet -, z.B. um eine neue Bahn 5 einzuführen. In der oberen Dichtposition reicht sein oberer Teil bis an die engste Stelle zwischen den beiden Tragwalzen 1, 2. Die obere, dem Tragwalzenspalt zugewandte Begrenzungsfläche weist einen sich zumindest über die minimale Bahnbreite erstreckenden Luftaustrittsschlitz 11 auf und ist an beiden Maschinenseiten als Führungsfläche für zwei an beiden Seiten der Maschine angeordnete stirnseitige Dichtelemente 12 ausgebildet. Die Form der stirnseitigen Dichtelemente 12 ist der freien Querschnittsfläche zwischen den Tragwalzen 1, 2 angepaßt, wobei ihr oberer Teil rechteckförmig bis oberhalb der Verbindungslinie zwischen den beiden Scheitelpunkten der Tragwalzen 1, 2 verlängert ist, um bei Wickelrollen 4 mit großem Durchmesser eine ausreichende Dichtfläche zu sichern. Sie sind in axialer Richtung - also quer zur Bahn 5 - verschiebbar an seitlichen Schwenkarmen 13 befestigt, deren Schwenkachse etwas exzentrisch versetzt nach außen auf der Verbindungslinie zwischen den beiden Tragwalzenachsen verläuft. Die Dichtelemente 12 können so aus dem Walzenbett 3 über die Tragwalze 2 in eine Position geschwenkt werden, bei der das Einfahren von seitlichen Führungsköpfen in die Hülsen 6 möglich ist. Die geringe Exzentrizität führt dazu, daß die den Tragwalzen 1, 2 zugewandten Seitenflächen der Dichtelemente 12 sich beim Ausschwenken etwas von der jeweiligen Tragwalzenoberfläche wegbewegen, z.B. um Papierreste entfernen zu können.To reduce the bearing weight of the
In den Luftkasten 8 ist ein Trennmesser 14 mit einer Abreißklinge 15 angeordnet, die sich in Dichtposition des Luftkastens 8 bis in das Walzenbett 3 hochbewegen und bis in den Luftkasten 8 absenken läßt. In Fig. 2 ist die Abreißklinge 15 abgesenkt, in Fig. 3 befindet sich sich in ihrer Trennposition in dem Walzenbett 3.In the
Die Abreißklinge 15 erstreckt sich über die gesamte Länge des Zufuhrschlitzes 15, also im wesentlichen über die gesamte Maschinenbreite. Sie ist am Ende eines ebenfalls maschinenbreiten Halters 16 in Form eines zweiseitigen Hebels befestigt, der etwa in seiner Mitte um eine zu den Tragwalzenachsen parallele Achse 17 drehbar am Ende einer senkrechten Stütze 18 angelenkt ist. Die Stütze 18 ist am Ende der Kolbenstangen 19 von senkrechten, hydraulischen Kolben-Zylinder-Einheiten befestigt, deren Zylinder 20 am Boden des Luftkastens 8 festgeschraubt sind und sich so an diesem abstützen. Am unteren Teil der Stütze 18 sind die Zylinder 21 von pneumatischen Kolben-Zylinder-Einheiten befestigt, deren Kolbenstangen 22 sich senkrecht nach oben erstrecken. Das Ende der Kolbenstangen 22 ist über Hebel 23 gelenkig mit dem Halter so verbunden, daß die Gelenkpunkte 24 mit dem Halter 16 bei vollständig eingefahrenen Kolbenstangen 22 gegenüber den Gelenkpunkten 25 mit den Kolbenstangen 22 etwas in Richtung zur Tragwalze 2 versetzt liegen. Dadurch wird die Abreißklinge 15 beim Ausfahren der Kolbenstangen 22 eindeutig in Richtung zur Tragwalze 1 bewegt, wie in Fig. 3 dargestellt ist. Damit der Halter 16 und die Hebel 23 gestreckt werden können, weist die Stütze 18 in ihrem oberen Teil Aussparungen auf, in die diese hineinbewegt werden können. Das der Abreißklinge 15 abgewandte Ende des Hebels 16 besteht aus einzelnen, mit Abstand voneinander angeordneten Laschen, wobei am Ende der jeweiligen Laschen abwechselnd einer der Hebel 23 angelenkt ist oder ein frei drehbares Rad 26 gelagert ist. Die Drehachse der frei drehbaren Räder 26 verläuft koaxial zu den Gelenkpunkten 24. Auch für die so in axialer Richtung versetzt zu den Hebeln 23 angeordneten Räder 26 sind Aussparungen in der Stütze 18 vorhanden, in die sie bewegt werden können. Der untere Teil der Stütze 18 mit den Kolben-Zylinder-Einheiten 21, 22 ist an senkrechten Führungen 27 geführt, die im oberen Teil des Luftkastens 8 angeordnet sind. An der Seite zur Tragwalze 2 sind in axialer Richtung versetzt zu den Führungen 27 weitere senkrechte Führungsschienen für die Räder 26 im oberen Teil des Luftkastens 8 befestigt, von denen die Kippstellung des Halters 16 bestimmt wird, während sich die Räder 26 noch im Luftkasten 8 befinden. Sobald die Räder 26 den Luftkasten 8 nach oben verlassen, werden sie von der Tragwalze 2 geführt und so die Kippbewegung des Halters 16 mit der Abreißklinge 15 festgelegt.The tear-off
Im vorliegenden Ausführungsbeispiel ist das gesamte Trennmesser mit seinem Hebemechanismus in dem Luftkasten 8 angeordnet. Ebenso ist es möglich, den Zylinder 20 der Kolben-Zylinder-Einheit 19, 20 außen an der Unterseite des Luftkastens 8 zu befestigen und die Kolbenstange 19 abgedichtet durch den Boden des Luftkastens 8 zu führen. Dies hat den Vorteil, daß die Versorgungsleitungen für die Kolben-Zylinder-Einheiten 19, 20 außerhalb des Luftkastens 8 angeordnet werden können. Falls es für die Stabilität des Luftkastens 8 erforderlich ist, senkrechte Querschotten in ihm anzuordnen, kann das Trennmesser 14 in einzelne (z.B. vier bei 8 m Arbeitsbreite) Segmente unterteilt werden, die in axialer Richtung aufeinanderfolgend angeordnet sind. Jedes dieser Segmente besteht dann aus den sich über die Segmentbreite durchgehend erstreckenden Teilen (Abreißklinge 15, Halter 16, Stütze 18), die von jeweils 2 seitlichen Kolben-Zylinder-Einheiten 19, 20 auf- und abbewegt werden und bei denen die Kippbewegung der Abreißklinge 15 durch 2 seitliche, am unteren Teil der Stütze 8 befestigten Kolben-Zylinder-Einheiten 21, 22 bewirkt wird.In the present exemplary embodiment, the entire cutting knife with its lifting mechanism is arranged in the
Sobald beim Aufwickeln das Auflagegewicht der Wickelrollen 4 einen bestimmten Wert überschreitet, werden die stirnseitigen Dichtelemente 12 in das Walzenbett 3 geschwenkt und axial gegen die Stirnseiten der Wickelrollen 4 bewegt. Der Luftkasten 8 ist hochgeschwenkt, so daß der untere Zwickel zwischen den Tragwalzen 1, 2 abgedichtet ist und die Dichtelemente 12 auf seine obere Begrenzungsfläche aufsetzen können. Dabei dichten sie den Luftaustrittsschlitz 11 außerhalb des Wickelrollenbereichs ab. Durch Einleiten von Druckluft in den Luftkasten 8 wird unter den Wickelrollen 4 ein Überdruck erzeugt, der das Auflagegewicht auf das gewünschte Maß vermindert. Die Druckluft tritt aus dem Luftaustrittsschlitz 11 aus, während alle Teile des Trennmessers 14 einschließlich der Abreißklinge 15 in den Luftkasten 8 versenkt sind. Diese Position ist in Fig. 2 dargestellt.As soon as the support weight of the winding
Nach Beendigung der Wicklung wird die Druckluftzufuhr abgeschaltet, die stirnseitigen Dichtelemente 12 werden aus dem Walzenbett 3 geschwenkt und die Abreißklinge 15 des Trennmessers 14 wird in die in Fig. 3 dargestellte Trennposition bewegt. Dazu wird zunächst Druckluft in die Zylinder 21 eingeleitet und so die Kolben 22 vorgespannt. Eine Kippbewegung des Halters 16 ist noch nicht möglich, da eine seitliche Bewegung der Räder 26 in Richtung zur Tragwalze 2 durch die Führungsschienen verhindert wird. Anschließend bewegen die Kolben-Zylinder-Einheiten 19, 20 die Abreißklinge 15 nach oben. Sobald die Räder 26 den Luftkasten 8 oben verlassen haben, werden sie von der Tragwalze 2 geführt. So erfolgt beim Hochbewegen der Abreißklinge 15 zugleich eine Kippbewegung in Richtung zur Tragwalze 1, ohne daß die Kolben-Zylinder-Einheiten 21, 22 gesteuert werden müssen. Die Höhe der Stütze 18, die Breite des Halters 16 und der Hub der Kolben 22 ist so gewählt, daß sich die Abreißklinge 15 beim Hochfahren der Kolbenstangen 19 exakt in ihre Trennposition im Walzenbett 3 mit geringem Abstand von der umschlungenen Tragwalze 1 bewegt. Anschließend werden die vollen Wickelrollen 4 über die nichtumschlungene Tragwalze 2 ausgestoßen, dabei reißt die Bahn 5 an der Abreißklinge 15 ab. Der so geschaffene neue Bahnanfang wird an der Tragwalze 1 gehalten, z.B. an dieser mit Unterdruck angesaugt. Anschließend wird die Abreißklinge 15 wieder in den Luftkasten 8 versenkt. Dazu wird zunächst die Abreißklinge 15 mit den Kolben-Zylinder-Einheiten 21, 22 in etwa senkrecht gestellt, anschließend bewegen die Kolben-Zylinder-Einheiten 19, 20 die Stütze 18 mit allen daran befestigten Teilen nach unten, bis sich die Abreißklinge 15 im Luftkasten 8 befindet.
