Description

Die Erfindung betrifft ein Verfahren zum Überführen eines Aufführstreifens einer Materialbahn, insbesondere Papier- oder Kartonbahn, auf eine Wickelvorrichtung zum Aufwickeln der Materialbahn auf einen Tambour, bei der die Matetrialbahn bzw. der Aufführstreifen über eine Tragtrommel geführt und zwischen der Tragtrommel und dem Tambour ein Wickelspalt gebildet wird. Sie betrifft ferner eine Wickelvorrichtung gemäß dem Oberbegriff des Anspruchs 17.The invention relates to a method for transferring a Aufführstreifens a material web, in particular paper or board web, on a winding device for winding the web onto a spool in which the Matetrialbahn or the Aufführstreifen performed on a carrier drum and between the carrier drum and the spool a winding nip is formed. It further relates to a winding device according to the preamble of claim 17.

Wickelvorrichtungen der zuvor genannten Art sind beispielsweise aus den Druckschriften DE 198 22 261 A1 , DE 198 52 257 A1 , DE 199 39 506 A1 , WO 98/52858 und EP 0 483 092 B1 bekannt.Winding devices of the aforementioned type are for example from the publications DE 198 22 261 A1 . DE 198 52 257 A1 . DE 199 39 506 A1 . WO 98/52858 and EP 0 483 092 B1 known.

Der bisher übliche allgemeine Ablauf eines entsprechenden Aufführvorgangs an einer Papiermaschine umfasst die folgenden Schritte:

  • Am Ende der Trockenpartie, d.h. am letzten Trockenzylinder, wird die Papierbahn bahnbreit in den Pulper oder Stoffauflöser gefahren.
  • Beispielsweise mittels eines Spitzenschneiders wird ein Streifen geschnitten.
  • Der Streifen wird vom letzten Trockenzylinder abgenommen und beispielsweise mittels einer Seilführung, Vakuumbändern, Luftblechen und/oder dergleichen auf eine Wickelvorrichtung oder Roller überführt.
  • Der Streifen wird aufgeholt und stramm gezogen.
  • Der Streifen wird auf volle Bahnbreite gefahren.
The hitherto usual general procedure of a corresponding threading operation on a paper machine comprises the following steps:
  • At the end of the dryer section, ie at the last drying cylinder, the paper web is moved to the web width in the pulper or material dissolver.
  • For example, by means of a lace cutter, a strip is cut.
  • The strip is removed from the last drying cylinder and transferred for example by means of a cable guide, vacuum bands, air sheets and / or the like on a winding device or roller.
  • The strip is caught up and pulled tight.
  • The strip is driven to full web width.

Als Klemmstelle für den Streifen dient hierbei der zwischen einer Tragtrommel und einem Leertambour gebildete Wickelspalt oder Nip.As a nip for the strip is used here formed between a carrier drum and a hollow spool winding nip or nip.

Die Linienkraft im Nip wird durch Anpressung erzeugt, wobei der Leertambour entsprechend gegen die Tragtrommel oder die Tragtrommel entsprechend gegen den Leertambour gepresst wird.The line force in the nip is generated by contact pressure, wherein the empty bobbin is pressed against the corresponding corresponding to the carrier drum or the carrier drum against the empty bambour.

Die Anpressung des Leertambours gegen die Tragtrommel bzw. der Tragtrommel gegen den Leertambour erfolgt üblicherweise mittels zweier Hydraulikzylinder, von denen einer auf der Führerseite und einer auf der Triebseite vorgesehen ist und die mit gleichem Druck beaufschlagt werden. Durch die gleichmäßige Anpressung bzw. gleiche Anpresskraft auf der Führerseite und der Triebseite ergibt sich ein über seine gesamte Breite geschlossener Nip.The pressing of the empty drum against the carrier drum or the carrier drum against the empty drum is usually carried out by means of two hydraulic cylinders, one of which is provided on the driver's side and one on the drive side and which are acted upon by the same pressure. Due to the uniform contact pressure or the same contact pressure on the driver's side and the drive side results in a closed over its entire width nip.

Überdies ist bisher allgemein eine Aufführposition auf der Schiene oder zwischen der Wechselposition und der waagrechten Position auf der Schiene vorgesehen. Die Verteilung der Linienkraft ist bisher allgemein abhängig von den folgenden Größen:

  • Höhe der Anpresskraft
  • Wechselposition (Wechselwinkel)
  • Steifigkeit von Tragtrommel und Tambour
  • Ausführung der Oberflächen von Tragtrommel und Tambour (Stahl, Gummierung, Härte)
  • Durchmesser von Tragtrommel und Tambour.
Moreover, hitherto, generally, a threading position has been provided on the rail or between the change position and the horizontal position on the rail. The distribution of line power has been generally dependent on the following quantities:
  • Height of the contact pressure
  • Change position (change angle)
  • Stiffness of carrier drum and drum
  • Design of the surfaces of carrier drum and drum (steel, rubber, hardness)
  • Diameter of carrier drum and drum.

Dabei ist die Verteilung der Linienkraft bzw. Pressung bezüglich der Maschinenmitte bisher stets symmetrisch.The distribution of the line force or pressure with respect to the machine center has always been symmetrical.

Beim Auf- oder Überführen des Aufführstreifens kann es insbesondere bei einer eingelaufenen gummierten Tragtrommel zu Problemen kommen. So bedeutet eine eingelaufende Tragtrommel eine Durchmesserreduzierung. Die Nipkraft bzw. Pressung ist an der betreffenden Stelle geringer, wobei im Extremfall der Nip an der betreffenden Stelle sogar offen sein kann, d.h. nicht mehr vollständig geschlossen ist. Der Überführstreifen kann dann nicht mehr gegriffen werden.When mounting or transferring the Aufführstreifens there may be problems especially in a run-in rubberized carrier drum. Thus, a running-in carrying drum means a diameter reduction. The nip force or pressure is lower at the point concerned, in which case in extreme cases the nip may even be open at the relevant point, i. not completely closed. The transfer strip can then no longer be grasped.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren sowie eine verbesserte Wickelvorrichtung der eingangs genannten Art zu schaffen, bei denen die zuvor genannten Probleme beseitigt sind. Dabei soll insbesondere sichergestellt sein, dass der Wickelspalt oder Nip an der Stelle, an der der Überführstreifen ankommt, in jedem Fall geschlossen ist.The invention has for its object to provide an improved method and an improved winding device of the type mentioned, in which the aforementioned problems are eliminated. In particular, it should be ensured that the winding nip or nip at the point where the transfer strip arrives, is closed in any case.

Bezüglich des Verfahrens wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass die Linienkraft im Wickelspalt beim Überführen des Aufführstreifes im Bereich des Aufführstreifens auf einen höheren Wert eingestellt wird als im restlichen Bereich des Wickelspaltes.With regard to the method, this object is achieved according to the invention in that the line force in the winding nip is adjusted to a higher value in the area of the threading strip during the transfer of the threading strip than in the remaining region of the winding nip.

Wird der Aufführstreifen in einem der beiden seitlichen Randbereiche durch den Wickelspalt geführt, so wird bevorzugt die Linienkraft in dem betreffenden seitlichen Randbereich des Wickelspaltes auf einen höheren Wert eingestellt als in dem anderen seitlichen Randbereich. Dabei kann die Linienkraft in dem anderen seitlichen Randbereich insbesondere auch auf den Wert Null eingestellt werden.If the leader strip is guided through the winding nip in one of the two lateral edge regions, the line force in the relevant lateral edge region of the winding nip is preferably set to a higher value than in the other lateral edge region. In this case, the line force in the other lateral edge region can in particular also be set to the value zero.

Gemäß einer bevorzugten praktischen Ausgestaltung des erfindungsgemäßen Verfahrens wird die Linienkraft auf der Führerseite und auf der Triebseite des Wickelspaltes auf unterschiedlich hohe Werte eingestellt, wobei sie auf der Seite des Aufführstreifens auf den höheren Wert eingestellt wird.According to a preferred practical embodiment of the method according to the invention, the line force on the leader side and on the drive side of the winding nip is adjusted to different high values, being set to the higher value on the side of the leader strip.

Die Linienkraft im Wickelspalt kann beispielsweise über einen verfahrbaren bzw. verstellbaren Tambour und/oder über eine verfahrbare bzw. verstellbare Tragtrommel eingestellt werden.The line force in the winding nip can be adjusted for example by means of a movable or adjustable drum and / or by means of a movable or adjustable carrying drum.

Ist die Linienkraft im Wickelspalt über einen verfahrbaren bzw. verstellbaren Tambour einstellbar, so wird Vorteilhafterweise der Tambour im Bereich des Aufführstreifens stärker gegen die Tragtrommel gepresst als im restlichen Bereich des Wickelspaltes.If the line force in the winding nip is adjustable by way of a movable or adjustable spool, the spool in the region of the threading strip is advantageously pressed more strongly against the carrying drum than in the remaining region of the winding nip.

Der Tambour kann insbesondere auch bezüglich der Tragtrommel schräg gestellt werden.The tambour can also be inclined in particular with respect to the carrier drum.

Zweckmäßigerweise wird eine ortsfeste Tragtrommel eingesetzt.Conveniently, a stationary carrier drum is used.

Der Aufführstreifen kann beispielsweise im Primärbereich oder im Sekundärbereich der Wickelvorrichtung aufgeführt werden. Was unter einem solchen Primär- bzw. Sekundärbereich der Wickelvorrichtung zu verstehen ist, ist dem Fachmann geläufig und ergibt sich z.B. aus den eingangs genannten Druckschriften. So kann z.B. im Primärbereich ein neuer Tambour bereitgestellt und in eine Tambourwechselposition verbracht werden, in der er mit der Tragtrommel einen neuen Wickel-spalt bildet. Dazu kann z.B. eine Primär-Transporteinrichtung vorgesehen sein. Anschließend kann dann beispielsweise eine Sekundär-Transpörteinrichtung den neuen Tambour mit der angefangenen neuen Wickelrolle übernehmen.The Aufführstreifen can be listed, for example, in the primary area or in the secondary area of the winding device. What is meant by such a primary or secondary region of the winding device is familiar to the person skilled in the art and results, for example, in from the publications mentioned above. Thus, e.g. in the primary area a new drum is provided and spent in a Tambourwechselposition in which he forms a new winding nip with the carrying drum. For this, e.g. be provided a primary transport device. Then then, for example, a secondary transfer device to take over the new drum with the new roll started.

Die Erfindung kann also beispielsweise bei einer solchen Wickelvorrichtung angewandt werden, wie sie in der EP 0 483 092 B1 beschrieben und bei der die Linienkraft im Wickelspalt über einen verfahrbaren bzw. verstellbaren Tambour einstellbar ist.The invention can thus be applied for example in such a winding device, as shown in the EP 0 483 092 B1 described and in which the line force in the winding nip is adjustable via a movable or adjustable spool.

Gemäß einer alternativen zweckmäßigen Ausgestaltung des erfindungsgemäßen Verfahrens wird die Linienkraft im Wickelspalt über eine verfahrbare bzw. verstellbare Tragtrommel eingestellt.According to an alternative expedient embodiment of the method according to the invention, the line force in the winding nip is adjusted via a movable or adjustable carrying drum.

Wird die Linienkraft im Wickelspalt über eine verfahrbare bzw. verstellbare Tragtrommel eingestellt, so wird bevorzugt die Tragtrommel im Bereich des Aufführstreifens stärker gegen den Tambour gepresst als im restlichen Bereich des Wickelspaltes.If the line force in the winding nip is adjusted by means of a movable or adjustable carrying drum, the carrying drum is preferably pressed more strongly against the tambour in the region of the tipping strip than in the remaining region of the winding nip.

Zweckmäßigerweise wird die Tragtrommel bezüglich des Tambours schräg gestellt.Conveniently, the carrier drum is tilted with respect to the drum.

Der Tambour kann insbesondere ortsfest bzw. zur Kompensation der Zunahme des Wickeldurchmessers verfahrbar sein.The spool can in particular be stationary or to compensate for the increase of the winding diameter movable.

Der Aufführstreifen kann entweder im Primärbereich oder im Sekundärbereich der Wickelvorrichtung aufgeführt werden.The leader strip can be listed either in the primary area or in the secondary area of the winding device.

Die Erfindung ist also insbesondere auch bei einer solchen Wickelvorrichtung anwendbar, wie sie z.B. in der WO 98/52858 beschrieben ist und bei der die Linienkraft im Wickelspalt über eine verfahrbare bzw. verstellbare Tragtrommel einstellbar ist.The invention is therefore particularly applicable to such a winding device, as for example in the WO 98/52858 is described and in which the line force in the winding nip is adjustable via a movable or adjustable support drum.

Aufgrund des erfindungsgemäßen Verfahrens ist ein sicheres Schließen des Wickeilspalts oder Nips an der Stelle sichergestellt, an der der Überführstreifen ankommt. In den meisten Fällen wird der Überführstreifen auf der Führerseite zugeführt werden. Ein entsprechendes zuverlässiges Schließen des Nips wird insbesondere durch ein stärkeres Anpressen an der betreffenden Stelle des Wickelspaltes erreicht, wobei der Wickelspalt oder Nip auf der Gegenseite sogar geöffnet werden kann, d.h. auf der Gegenseite kann die Linienkraft auch auf den Wert Null reduziert werden.Due to the method according to the invention a secure closing of the Wickeilspalts or nip is ensured at the point where the transfer strip arrives. In most cases, the transfer strip will be fed to the driver's side. A corresponding reliable closing of the nip is achieved in particular by a stronger pressing at the relevant point of the winding nip, wherein the winding nip or even on the opposite side can be opened, ie on the opposite side, the line force can also be reduced to the value zero.

Es wird also für eine asymmetrische Verteilung der Linienkraft gesorgt, wobei insbesondere die Linienkraft auf der Führerseite von der auf der Triebseite verschieden sein kann.Thus, an asymmetrical distribution of the line force is provided, wherein in particular the line force on the driver side can be different from that on the drive side.

Auf der vom Aufführstreifen abgewandten Seite kann die Tragtrommel bzw. der Tambour schief gestellt werden. Auf der vom Aufführstreifen abgewandten Seite, z.B. der Triebseite, ergibt sich dann eine Linienkraft Null.On the side facing away from the leader strip, the carrier drum or the drum can be skewed. On the side facing away from the leader, e.g. the drive side, then results in a line force zero.

Beispielsweise in dem Fall, dass die Linienkraft im Wickelspalt über eine verfahrbare bzw. verstellbare Tragtrommel einstellbar ist, kann beispielsweise wie folgt vorgegangen werden:

  • Zum Öffnen der vom Aufführstreifen abgewandten Seite des Nips wird die Tragtrommel schief gestellt. Dies kann beispielsweise wie folgt geschehen:
    • Die Tragtrommel wird beispielsweise hydraulisch über Zylinder der Tragtrommelanpressung weggefahren, wobei die Position des Leertambours im Primärarm der Primärlagerung fixiert sein kann.
    • Alternativ kann die Tragtrommel über einen zusätzlichen Zylinder weggefahren werden.
    • Der Tambour kann beispielsweise über einen Elektroantrieb, beispielsweise einen Servomotor oder dergleichen weggefahren werden. Die Tragtrommel auf der betreffenden Seite kann gegen einen Anschlag fahren.
For example, in the case that the line force in the winding nip is adjustable via a movable or adjustable carrying drum, for example, the following procedure can be adopted:
  • To open the side facing away from the leader strip of the nip the carrier drum is skewed. This can be done, for example, as follows:
    • The carrier drum is moved away, for example, hydraulically via cylinders of the carrier drum pressing, wherein the position of the empty drum in the primary arm of the primary storage can be fixed.
    • Alternatively, the carrier drum can be moved away via an additional cylinder.
    • The spool can be moved away, for example via an electric drive, such as a servo motor or the like. The carrier drum on the relevant side can move against a stop.

Der Aufführstreifen kann z.B. im Primärbereich (Position Leertambour im Primärarm fixiert) oder im Sekundärbereich (Position Leertambour durch Sekundärschlitten gegeben) aufgeführt werden.For example, the leader strip can be listed in the primary area (empty bobbin position fixed in the primary arm) or in the secondary area (empty bobbin position by secondary slide).

Bei einem Aufführen im Primärbereich kann die Tragtrommel z.B. hydraulisch über Zylinder der Tragtrommelanpressung auf der vom Aufführstreifen abgewandten Seite, z.B. der Triebseite, weggefahren werden, wodurch sich ein entsprechender Spalt ergibt. Es kann auch die Tragtrommel auf der vom Aufführstreifen abgewandten Seite, z.B. der Triebseite, gegen einen Anschlag fahren, wodurch sich ebenfalls wieder ein entsprechender Spalt ergibt.For example, in the primary area, the carrier drum can be used e.g. hydraulically via cylinders of the carrier drum presser on the side facing away from the leader, e.g. the drive side, are driven away, resulting in a corresponding gap. It may also be the carrier drum on the side facing away from the leader strip, e.g. the drive side, drive against a stop, which also results in a corresponding gap again.

Beim Aufführen des Aufführstreifens im Sekundärbereich kann die Tragtrommel auf der vom Aufführstreifen abgewandten Seite, insbesondere der Triebseite, beispielsweise wieder hydraulisch über Zylinder der Tragtrommelanpressung weggefahren werden, wodurch sich ein entsprechender Spalt ergibt. Es kann auch der Sekundärschlitten auf der vom Aufführstreifen abgewandten Seite, z.B. der Triebseite, soweit weggefahren werden, dass die Tragtrommel auf der vom Aufführstreifen abgewandten Seite gegen einen Anschlag fährt, wodurch sich wieder ein entsprechender Spalt ergibt.When performing the Aufführstreifens in the secondary area, the carrier drum on the side facing away from the tail strip, in particular the drive side, for example, be moved back hydraulically cylinder over the Tragtrommelanpressung, resulting in a corresponding gap. The secondary carriage may also be located on the side facing away from the leader strip, e.g. the drive side, as far as being driven away, that the carrier drum moves on the side facing away from the leader side against a stop, which again results in a corresponding gap.

Auch dann, wenn die Linienkraft im Wickelspalt über einen verfahrbaren bzw. verstellbaren Tambour einstellbar ist, kann das Aufführen beispielsweise wieder im Primärbereich oder im Sekundärbereich der Wickelvorrichtung erfolgen.Even if the line force in the winding nip is adjustable via a movable or adjustable spool, the threading can, for example, again take place in the primary area or in the secondary area of the winding device.

Bei einem Aufführen im Primärbereich (Leertambour im Primärschlitten geklemmt/Primärschlitten relativ zum Primärarm der Primärlagerung beweglich) sind beispielsweise die folgenden Schritte denkbar:

  • Der Primärschlitten wird beispielsweise hydraulisch auf der vom Aufführstreifen abgewandten Seite, z.B. der Triebseite, weggefahren, wodurch sich ein entsprechender Spalt ergibt.
  • Der Primärschlitten wird auf Anschlag gefahren, wodurch sich wieder ein entsprechender Spalt ergibt.
For example, the following steps are conceivable when performing in the primary area (empty mandrel clamped in the primary carriage / primary carriage movable relative to the primary arm of the primary storage):
  • The primary carriage is, for example, hydraulically moved away on the side facing away from the guide strip, for example the drive side, resulting in a corresponding gap.
  • The primary carriage is driven to stop, which again results in a corresponding gap.

Bei einem solchen Aufführen im Primärbereich kann generell der Tambourhalter etwas geöffnet werden.With such a performance in the primary area, the tambour holder can generally be opened somewhat.

Beim Aufführen im Sekundärbereich (Leertambour im Sekundärschlitten geklemmt) kann im vorliegenden Fall einer entsprechenden Beeinflussung der Linienkraft über den verfahrbaren bzw. verstellbaren Tambour z.B. wie folgt vorgegangen werden:

  • Der Sekundärschlitten wird beispielsweise hydraulisch von der Tragtrommel auf der vom Aufführstreifen abgewandten Seite, z.B. auf der Triebseite, weggefahren, wodurch sich ein entsprechender Spalt ergibt.
  • Der Sekundärschlitten wird auf Anschlag gefahren, wodurch sich ein entsprechender Spalt ergibt.
When performing in the secondary area (empty mandrel clamped in the secondary carriage), in the present case, a corresponding influencing of the line force via the movable or adjustable spool can be carried out, for example, as follows:
  • The secondary carriage is, for example, hydraulically moved away from the carrier drum on the side facing away from the guide strip, for example on the drive side, resulting in a corresponding gap.
  • The secondary carriage is driven to stop, resulting in a corresponding gap.

Beim Aufführen im Sekundärbereich (Leertambour mittels Sekundärhebeln gegen Tragtrommel gepresst) kann beispielsweise auch wie folgt vorgegangen werden:

  • Der Sekundärhebel wird nicht vollständig angelegt, um einen entsprechenden Spalt zu erhalten.
  • Der Sekundärhebel wird auf Anschlag gefahren, um einen entsprechenden Spalt zu erhalten.
When performing in the secondary area (empty drum pressed by means of secondary levers against carrier drum) can for example also proceed as follows:
  • The secondary lever is not fully applied to obtain a corresponding gap.
  • The secondary lever is moved to stop to obtain a corresponding gap.

Beim Aufführen im Sekundärbereich kann bei einer entsprechenden Beeinflussung der Linienkraft über einen verfahrbaren bzw. verstellbaren Tambour also beispielsweise so vorgegangen werden, dass der Sekundärhebel bzw. Sekundärschlitten nicht vollständig angelegt wird, woraus folgt, dass der Leertambour nicht vollständig anliegt.When performing in the secondary area, it is thus possible, for example, to proceed with a corresponding influencing of the line force via a movable or adjustable drum so that the secondary lever or secondary carriage is not completely applied, as a result of which the empty drum is not fully seated.

Die erfindungsgemäße Wickelvorrichtung ist entsprechend dadurch gekennzeichnet, dass zum Überführen eines Aufführstreifes der Materialbahn die Linienkraft im Wickelspalt im Bereich des Aufführstreifens auf einen höheren Wert einstellbar ist als im restlichen Bereich des Wickelspaltes.The winding device according to the invention is characterized in that for transferring a Aufführstreifes the web, the line force in Winding gap in the area of the Aufführstreifens is set to a higher value than in the remaining area of the winding nip.

Bevorzugte Ausführungsformen der erfindungsgemäßen Wickelvorrichtung sind in den Unteransprüchen angegeben.Preferred embodiments of the winding device according to the invention are specified in the subclaims.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher beschrieben; in dieser zeigen:

Figur 1
eine schematische Draufsicht einer Wickelvorrichtung gemäß dem Stand der Technik, bei der eine verfahrbare bzw. verstellbare Tragtrommel bis zum Überführen des Aufführstreifens auf den beiden Seiten mit gleich großen Anpresskräften gegen den Tambour gepresst wird,
Figur 2
eine schematische Draufsicht einer erfindungsgemäßen Wickelvorrichtung, bei der die verfahrbare bzw. verstellbare Tragtrommel beim Überführen des Aufführstreifens auf der Seite des Aufführstreifens mit einer höheren Anpresskraft als auf der anderen Seite gegen den Tambour gepresst wird, wobei auf beiden Seiten jeweils eine Anpresskraft größer Null erzeugt wird, und
Figur 3
eine schematische Draufsicht einer weiteren Ausführungsform der erfindungsgemäßen Wickelvorrichtung, wobei im vorliegenden Fall die Tragtrommeln jedoch schräg gestellt, d.h. der Wickelspalt auf der vom Überführstreifen abgewandten Seite geöffnet wird, so dass auf dieser Seite die Anpresskraft auf Null reduziert ist.
The invention will be described in more detail below with reference to an embodiment with reference to the drawing; in this show:
FIG. 1
a schematic plan view of a winding device according to the prior art, in which a movable or adjustable carrier drum is pressed until transferring the Aufführstreifens on the two sides with equal pressing forces against the spool,
FIG. 2
a schematic plan view of a winding device according to the invention, in which the movable or adjustable support drum is pressed during transfer of the Aufführstreifens on the side of the Aufführstreifens with a higher contact force than on the other side against the spool, on both sides in each case a contact force greater than zero is generated , and
FIG. 3
a schematic plan view of another embodiment of the winding device according to the invention, in the present case, however, the support drums obliquely, ie the winding nip is opened on the side facing away from the transfer strip side, so that on this side, the contact pressure is reduced to zero.

Figur 1 zeigt in schematischer Draufsicht eine Wickelvorrichtung 10 gemäß dem Stand der Technik, bei der eine verfahrbare bzw. verstellbare Tragtrommel 12 beim Überführen des Aufführstreifens auf den beiden Seiten mit gleich großen Anpresskräften F1, F2 gegen den Tambour 14 gepresst wird. Im zwischen der Tragtrommel 12 und dem Tambour 14 gebildeten Nip oder Wickelspalt 16 ergibt sich somit eine symmetrische Verteilung der Linienkraft LK.Figure 1 shows a schematic plan view of a winding device 10 according to the prior art, in which a movable or adjustable support drum 12 during transfer of the Aufführstreifens on the two sides with equal pressing forces F 1 , F 2 is pressed against the spool 14. In formed between the carrier drum 12 and the spool 14 nip or winding nip 16 thus results in a symmetrical distribution of the line force LK.

Figur 2 zeigt in schematischer Draufsicht eine beispielhafte Ausführungsform einer erfindungsgemäßen Wickelvorrichtung 18 zum Aufwickeln einer Materialbahn, insbesondere Papier- oder Kartonbahn, auf einen Tambour 20, bei der die Materialbahn bzw. der Aufführstreifen wieder über eine Tragtrommel 22 geführt und zwischen der Tragtrommel 22 und dem Tambour 20 ein Wickelspalt 24 gebildet wird.Figure 2 shows a schematic plan view of an exemplary embodiment of a winding device 18 according to the invention for winding a material web, in particular paper or board web, on a spool 20, in which the material web or the Aufführstreifen again passed over a carrier drum 22 and between the carrier drum 22 and the Tambour 20 a winding nip 24 is formed.

Beim vorliegenden Ausführungsbeispiel der erfindungsgemäßen Wickelvorrichtung 18 wird die verfahrbare bzw. verstellbare Tragtrommel 22 beim Überführen des Aufführstreifens auf der Seite des Aufführstreifens mit einer höheren Anpresskraft F1 als auf der anderen Seite gegen den Tambour 20 gepresst. Im vorliegenden Fall wird auf beiden Seiten jeweils eine Anpresskraft größer Null erzeugt, was bedeutet, dass auch die gegenüber der Anpresskraft F1 kleinere Anpresskraft F2 auf der vom Aufführstreifen abgewandten Seite noch größer Null ist.
Figur 3 zeigt in schematischer Draufsicht eine weitere Ausführungsform der erfindungsgemäßen Wickelvorrichtung 18.In the present embodiment of the winding device 18 according to the invention, the movable or adjustable carrier drum 22 is pressed against the spool 20 when transferring the leader strip on the side of the leader strip with a higher contact pressure F 1 than on the other side. In the present case, a contact pressure greater than zero is generated on both sides, which means that even with respect to the contact pressure F 1 smaller contact force F 2 on the side facing away from the leader side is even greater zero.
FIG. 3 shows a schematic plan view of a further embodiment of the winding device 18 according to the invention.

Im vorliegenden Fall wird die Tragtrommel 22 bezüglich des Tambours 20 jedoch schräg gestellt, so dass die Tragtrommel 22 nur noch auf der Seite des Aufführstreifens mit der Anpresskraft F1 gegen den Tambour 20 gepresst wird, während der Wickelspalt 24 auf der vom Überführstreifen abgewandten Seite um den Betrag a geöffnet wird, so dass auf dieser Seite die Anpresskraft auf Null reduziert ist.In the present case, however, the carrier drum 22 is inclined relative to the main cylinder 20, so that the carrier drum 22 is pressed against the tambour 20 only on the side of the leader strip with the contact pressure F 1 , while the winding gap 24 on the side facing away from the transfer strip the amount a is opened, so that on this side the contact force is reduced to zero.

Auch im vorliegenden Fall ergibt sich somit wieder eine asymmetrische Verteilung der Linienkraft LK.In the present case, too, an asymmetrical distribution of the line force LK thus results again.
