such as in particular a paper or cardboard web on a reel, at
which the material web is guided over a carrying drum and between the
Carrier drum and the drum a winding gap is formed and the
Material web is cut for a respective reel change. she
further relates to a winding machine according to the preamble of
Eine entsprechende Wickelmaschine wird beispielsweise am Ende einer der Herstellung oder Veredelung einer Materialbahn dienenden Maschine eingesetzt. Sie kann beispielsweise aber auch dazu dienen, eine bereits fertig gewickelte Wickelrolle umzuwickeln. Bei der betreffenden Maschine kann es sich beispielsweise um eine Papier-, Karton- oder Tissuemaschine handeln.A corresponding winding machine is, for example, at the end of a the manufacture or refinement of a machine that serves as a material web used. However, it can also serve, for example, to already have one to wind the finished wound reel. On the machine in question it can be, for example, a paper, cardboard or tissue machine act.
Bei den bisher üblichen Wickelmaschinen der eingangs genannten Art wird die Materialbahn in der Regel mittels Kreismessern, Abschlagmessern oder Wasserstrahldüsen über die gesamte Breite getrennt.In the previously used winding machines of the type mentioned the material web is usually using circular knives, knives or water jet nozzles separated over the entire width.
In der EP 0 543 788 A1 ist ein Trennverfahren beschrieben, bei dem z.B.
zwei Wasserstrahldüsen von der Bahnmitte aus zu den Bahnrändern bewegt
werden und somit die Materialbahn vollständig vom Startpunkt des
Schneidvorgangs bis zum Bahnrand trennen. Die Startpunkte können einen
Abstand besitzen, so daß je nach Bewegungsrichtung der Düsen ein
nicht geschnittener Steg einer bestimmten Breite verbleibt oder eine Spitze
entsteht.
In der deutschen Offenlegungsschrift DE 44 01 804 A1 ist ein
Verfahren und eine Wickelmaschine zum Aufwickeln einer Bahn aus
Papier, Folie oder dergleichen zu einem Wickel beschrieben. Die
dargestellte Wickelmaschine weist eine Trennvorrichtung in Form
eines Rohres auf, welches die Bahn vor Beginn des Trennvorgangs in
Form einer Schleife auslenkt. In der ausgelenkten Position wird ein
Messer aus der Mantelfläche des Rohres ausgefahren und die Bahn
durchtrennt. Das Messer kann sich jedoch nur über einen Teil der
Länge des Rohres erstrecken. Es genügt, die Bahn nur an einer Stelle
zu schwächen. Nach dem Anritzen der Bahn kann an das Rohrinnere
Luftdruck angeschlossen werden, so daß Luft durch entsprechende
Schlitze im Rohr austritt und die Bahn restlos durchtrennt.In German published
Weiterhin offenbart die PCT-Anmeldung WO 97/48632 eine Wickelmaschine zum Aufwickeln einer Materialbahn wie insbesondere einer Papier- oder Kartonbahn auf einen Tambour, bei der die Materialbahn über eine Tragtrommel geführt und zwischen der Tragtrommel und dem Tambour ein Wickelspalt gebildet wird und die Materialbahn für einen jeweiligen Tambourwechsel durchtrennt wird, wobei wenigstens ein allgemein quer zur Bahnlaufrichtung verfahrbares Schneidelement über eine Steuer- und/oder Regeleinrichtung so beaufschlagbar ist, daß die Materialbahn mittels dieses Schneidelements lediglich über einen Teil der Bahnbreite durchtrennt wird.Furthermore, PCT application WO 97/48632 discloses one Winding machine for winding a material web like in particular a paper or cardboard web on a reel, at of the material web over a support drum and between the winding drum and the drum a winding gap is formed and cuts the material web for a respective reel change , at least one generally transverse to the direction of web travel movable cutting element via a control and / or Control device can be acted on so that the material web by means of this cutting element only over part of the web width is severed.
Zunehmende Maschinengeschwindigkeiten und -breiten erfordern immer größer werdende Schneidgeschwindigkeiten der Schneidelemente quer zur Bahnlaufrichtung. Wird das Geschwindigkeitsverhältnis zwischen Schneidelement und Papierbahn zu klein, so wird die Wickelqualität, die beispielsweise von der Wickelhärte und der Durchmesserkonstanz abhängt, insbesondere im Kernbereich des Wickels über die Breite aufgrund einer unterschiedlichen Anzahl von Wickellagen ungleichmäßig. Dies führt dazu, daß größere Mengen Papier aus dem Kernbereich nicht nutzbar sind und verworfen werden müssen.Increasing machine speeds and widths always require increasing cutting speeds of the cutting elements across Web direction. If the speed ratio between Cutting element and paper web too small, so the winding quality for example depends on the winding hardness and the constant diameter, especially in the core area of the roll due to the width a different number of winding layers unevenly. this leads to to the fact that larger amounts of paper from the core area are unusable and have to be discarded.
Ziel der Erfindung ist es, ein Verfahren sowie eine Wickelmaschine der eingangs genannten Art zu schaffen, mit denen sich die Dauer des Trennvorgangs verkürzen läßt und die Wickelqualität sowie die Wirtschaftlichkeit erhöht werden.The aim of the invention is to provide a method and a winding machine to create the type mentioned above, with which the duration of the separation process can shorten and the winding quality and economy increase.
Hinsichtlich des Verfahrens wird diese Aufgabe dadurch gelöst, daß die Reißspannung in Abhängigkeit von der Papiersorte, dem Flächengewicht und/oder der gewünschten minimalen Breite der durch die beiden Randabschnitte gebildeten Zone (III) bzw. des beispielsweise mittleren Bahnabschnitts gewählt und einem Regler (44) vorgegeben wird. Der Regler kann wieder Teil einer entsprechenden Steuer- und/oder Regelüngseinrichtung sein. With regard to the method, this object is achieved by that the tensile strength depends on the type of paper, the basis weight and / or the desired minimum width by the two edge sections formed zone (III) or the middle section, for example, selected and a controller (44) is specified. The controller can part again a corresponding control and / or regulation device his.
Die erfindungsgemäße Wickelmaschine ist dadurch gekennzeichnet, daß die Reißspannung in Abhängigkeit von der Papiersorte, dem Flächengewicht und/oder der gewünschten minimalen Breite der durch die beiden Randabschnitte gebildeten Zone (III) bzw. des beispielsweise mittleren Bahnabschnitts wählbar ist und einem Regler vorgegeben wird.The winding machine according to the invention is characterized in that that the tensile strength depends on the type of paper, the basis weight and / or the desired minimum width by the two edge sections formed zone (III) or the middle section, for example, selectable and is given to a controller.
Der Grundgedanke der Erfindung besteht somit darin, die Materialbahn durch das bzw. die Schneidelemente lediglich teilweise zu durchtrennen und den verbindenden Teil anschließend abzureißen.The basic idea of the invention is therefore the material web only partially cut by the cutting element or elements and then tear off the connecting part.
Dabei kann eine Zone den Bahnschwanz mit der Bahnspitze zur sicheren Führung zum neuen Tambour verbinden.A zone can secure the web tail with the web tip Connect the tour to the new drum.
In bestimmten Fällen ist es zweckmäßig, wenn die Reißspannung zumindest teilweise durch Erhöhen des Drehmoments des vollen Tambours erzeugt wird. Hierbei kann die Drehzahl der Walzen einer den Papierzug aufrechterhaltenden Einrichtung wie beispielsweise eines Glättwerks oder dergleichen beibehalten werden.In certain cases it is useful if the tensile strength at least generated in part by increasing the torque of the full reel becomes. The speed of the rollers can maintain the paper tension Equipment such as a smoothing machine or the like can be maintained.
Grundsätzlich ist es auch möglich, die Reißspannung zumindest teilweise durch Verringern des Drehmoments des neuen Tambours zu erzeugen. Dabei kann die Zugspannung über die Bahnbreite auf die abzureißende Zone verlagert werden.In principle, it is also possible to at least partially tear the tensile stress by reducing the torque of the new drum. The tension can be torn across the width of the web Zone.
Die Reißspannung kann zumindest teilweise auch durch Erhöhen des Drehmoments der Tragtrommel erzeugt werden.The tensile strength can be at least partially increased by increasing the Torque of the support drum are generated.
Bei einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Wickelmaschine wird die Reißspannung zumindest teilweise durch Erhöhen des Drehmoments der Tragtrommel und durch Erhöhen des Drehmoments des neuen Tambours erzeugt.In an expedient practical embodiment of the invention Method or the winding machine according to the invention is the Tear stress at least in part by increasing the torque of the Carrying drum and by increasing the torque of the new drum generated.
Bei einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Wickelvorrichtung umfaßt der zunächst verbleibende und anschließend abzureißende Teil der Materialbahn wenigstens einen einem jeweiligen Bahnrand benachbarten Randabschnitt.In an expedient practical embodiment of the invention Method or the winding device according to the invention comprises the part of the material web that is initially remaining and then to be torn off at least one adjacent to a respective web edge Edge section.
Grundsätzlich kann der zunächst verbleibende und anschließend abzureißende Teil der Materialbahn auch einen in Querrichtung betrachtet beispielsweise mittleren Bahnabschnitt umfassen.Basically, the one that remains initially and then can be demolished Part of the material web also viewed in the transverse direction, for example include middle track section.
Eine zweckmäßige praktische Ausführungsform zeichnet sich dadurch aus, daß der zunächst verbleibende und anschließend abzureißende Teil der Materialbahn wenigstens einen einem jeweiligen Bahnrand benachbarten Randabschnitt umfaßt und ein den Bahnschwanz mit der neu gebildeten Bahnspitze verbindender beispielsweise mittlerer Bahnabschnitt erzeugt wird oder daß der zunächst verbleibende und anschließend abzureißende Teil der Materialbahn einen beispielsweise mittleren Bahnabschnitt umfaßt und wenigstens ein den Bahnschwanz mit der neu gebildeten Bahnspitze verbindender Randabschnitt erzeugt wird.An expedient practical embodiment is characterized by this from that the first remaining and then demolished part the material web at least one adjacent to a respective web edge Edge section includes and a web tail with the newly formed For example, a central section of the web connecting the web tip is generated or that the remaining one and then demolished Part of the material web, for example a middle web section comprises and at least one of the web tail with the newly formed Edge section connecting the web tip is generated.
Dabei können die beiden Schneidelemente beispielsweise im Abstand voneinander in einem in Querrichtung beispielsweise mittleren Bahnbereich angesetzt und anschließend bei laufender Materialbahn in entgegengesetzter Richtung nach außen verfahren werden. In diesem Fall werden die beiden Randabschnitte der Materialbahn anschließend abgerissen.The two cutting elements can be spaced apart, for example in a transverse web area, for example in the middle applied and then in the opposite direction while the material web is running Outward direction. In this case, the then torn off the two edge sections of the material web.
Die Breite der durch die beiden Randabschnitte gebildeten Zone kann beispielsweise größer sein als die des beispielsweise mittleren Bahnabschnitts. Alternativ oder zusätzlich kann die Breite dieser Zone in Abhängigkeit von der Papiersorte und/oder dem Flächengewicht gewählt werden.The width of the zone formed by the two edge sections can, for example be greater than that of the middle path section, for example. Alternatively or additionally, the width of this zone can be dependent be selected from the paper type and / or the basis weight.
Die Breite der durch die beiden Randabschnitte gebildeten Zone beträgt beispielsweise etwa 1/24, insbesondere etwa 1/12 und vorzugsweise etwa 1/4 der Bahnbreite.The width of the zone formed by the two edge sections is for example about 1/24, in particular about 1/12 and preferably about 1/4 of the web width.
Bei einer bevorzugten praktischen Ausführungsform wird die Bahnspannung beim Erreichen der vorgebbaren minimalen Breite der durch die beiden Randabschnitte gebildeten Zone kurzzeitig erhöht, um diese Zone abzureißen. In a preferred practical embodiment, the web tension when the predetermined minimum width is reached by the two Edge sections formed zone briefly increased to tear off this zone.
Von Vorteil ist auch, wenn die Bahnspannung im Bereich des bzw. der Schneidelemente so gewählt wird, daß die durch die beiden Randabschnitte gebildete Zone der Materialbahn bei Erreichen einer vorgebbaren minimalen Zonenbreite reißt.It is also advantageous if the web tension in the area of the Cutting elements is chosen so that by the two edge sections formed zone of the material web upon reaching a predeterminable minimum zone width tears.
Bei einer weiteren vorteilhaften Ausführungsform werden die beiden Schneidelemente in jeweiligen Abstand von den beiden Bahnrändern angesetzt und anschließend bei laufender Materialbahn nach innen verfahren. In diesem Fall wird der beispielsweise mittlere Bahnabschnitt abgerissen.In a further advantageous embodiment, the two Cutting elements set at a respective distance from the two web edges and then move inwards while the material web is running. In this case, the middle section of the web, for example, is torn off.
Hierbei kann die Breite des beispielsweise mittleren Bahnabschnitts beispielsweise größer sein als die der durch die beiden Randabschnitte gebildeten Zone. Alternativ oder zusätzlich kann die Breite dieses beispielsweise mittleren Bahnabschnitts in Abhängigkeit von der Papiersorte und/oder dem Flächengewicht gewählt werden.The width of the middle web section, for example, can be used here be larger than that formed by the two edge sections Zone. Alternatively or additionally, the width of this can be, for example middle web section depending on the paper type and / or the basis weight can be selected.
Die Breite dieses beispielsweise mittleren Bahnabschnitts beträgt zweckmäßigerweise etwa 1/24, insbesondere etwa 1/12 und vorzugsweise etwa 1/4 der Bahnbreite.The width of this, for example, middle web section is expediently about 1/24, especially about 1/12 and preferably about 1/4 of the web width.

Von Vorteil ist auch, wenn die Bahnspannung im Bereich des bzw. der Schneidelemente so gewählt wird, daß der beispielsweise mittlere Abschnitt bei Erreichen einer vorgebbaren minimalen Breite dieses Abschnitts reißt.It is also advantageous if the web tension in the area of the Cutting elements is chosen so that the middle section, for example when a predeterminable minimum width of this section is reached tears.
Als jeweiliges Schneidelement kann beispielsweise ein Wasserstrahl- oder Laserstrahl-Schneidelement verwendet werden. Grundsätzlich ist jedoch auch der Einsatz anderer Schneidelemente denkbar.A water jet or Laser beam cutting element can be used. Basically, however the use of other cutting elements is also conceivable.
Vorzugsweise wird wenigstens ein Schneidelement so verfahren, daß die sich durch dieses Schneidelement ergebende Schnittlinie eine parabelartige Form besitzen. Dabei besitzt die jeweilige Parabelform zweckmäßigerweise eine nach außen zu den Bahnrändern hin gerichtete Wölbung. Grundsätzlich ist jedoch auch eine nach innen gerichtete Wölbung der betreffenden Parabelform denkbar.Preferably, at least one cutting element is moved so that the a cutting line resulting from this cutting element is a parabolic To have shape. The respective parabolic shape expediently has an outward curvature towards the edges of the web. In principle, however, an inward curvature is also the concerned parabolic shape conceivable.
In bestimmten Fällen ist es von Vorteil, wenn wenigstens ein Schneidelement so verfahren wird, daß die sich durch dieses Schneidelement ergebende Schnittlinie zumindest angenähert eine S-Form besitzt.In certain cases it is advantageous if at least one cutting element is operated so that the resultant by this cutting element Cutting line has at least approximately an S shape.
Die Bahnlaufgeschwindigkeit kann zweckmäßigerweise größer oder gleich etwa 1700 m/min, insbesondere größer oder gleich etwa 1800 m/min und vorzugsweise größer oder gleich etwa 2000 m/min gewählt werden.The web running speed can expediently be greater or equal about 1700 m / min, in particular greater than or equal to about 1800 m / min and preferably greater than or equal to about 2000 m / min.
Bei der Materialbahn kann es sich beispielsweise um eine Papierbahn mit einem Flächengewicht kleiner oder gleich etwa 250 g/m2 und vorzugsweise kleiner oder gleich etwa 150 g/m2 handeln.The material web can be, for example, a paper web with a basis weight less than or equal to about 250 g / m 2 and preferably less than or equal to about 150 g / m 2 .
Die Materialbahn kann von der Oberseite oder auch von der Unterseite her geschnitten werden. The material web can be from the top or from the bottom be cut here.

Hierzu kann insbesondere eine entsprechende Steuer- und/oder Regeleinrichtung vorgesehen sein. In a preferred practical embodiment, this is accomplished the minimum width that can be specified by the two edge sections formed zone or reaching the predetermined minimum width of the for example middle section by means of at least one position sensor detected about the position of the cutting element or elements, the corresponding is compared with a relevant setpoint.

Figur 1 zeigt in rein schematischer Darstellung eine beispielhafte Ausführungsform
einer erfindungsgemäßen Wickelmaschine 10 zum Aufwickeln
einer Materialbahn 12 auf einen Tambour 14, 14'. Bei der Materialbahn
12 kann es sich insbesondere um eine Papier- oder Kartonbahn handeln. Figure 1 shows a purely schematic representation of an exemplary embodiment
a winding
Die Wickelmaschine 10 kann somit insbesondere am Ende einer Papier-,
Karton- oder Tissuemaschine vorgesehen sein.The winding
Zur Herstellung einer Wickelrolle 16 wird die Materialbahn 12 im Anschluß
an eine Breitstreckwalze 18 über eine Tragtrommel 20 geführt, die
mit einem leeren Tambour 14' bzw. der entstehenden Wickelrolle 16 eines
bereits angewickelten Tambours 14 einen Wickelspalt 22 bildet. Die Tragtrommel
20 und die entstehende Wickelrolle 16 werden während des Wikkelvorgangs
miteinander in Kontakt gehalten, um diesen Wickelspalt 16
aufrechtzuerhalten. In der Figur 1 ist zudem ein oberhalb der Tragtrommel
20 bereitgestellter neuer Tambour 14" zu erkennen, der beim vorliegenden
Ausführungsbeispiel zum Anwickeln in die Position überführt
wird, die in der Figur 1 der neue Tambour 14' einnimmt.To produce a winding
Die Tragtrommel 20 ist über einer zu einem darunter liegenden Ausschußauflöser
24 führenden Öffnung 26 eines Fundaments 28 angeordnet
und in einem unteren Bereich mit einem Schaber 30 versehen.The
In Bahnlaufrichtung L vor der Tragtrommel sowie vor der Breitstreckwalze
18 ist die Materialbahn 12 durch einen zwischen zwei angetriebenen Walzen
30, 32 gebildeten Spalt geführt. Über diese beiden angetriebenen Walzen
32, 34, die beispielsweise einem Glättwerk zugeordnet sein können,
kann während des Betriebs ein vorgebbarer Bahnzug eingehalten werden.In the web running direction L in front of the carrier drum and in front of the
Wie anhand der Figur 1 zu erkennen ist, sind beim dargestellten Ausführungsbeispiel
auch die Tragtrommel 20 und der Tambour 14, 14' vorzugsweise
durch einen jeweiligen Zentrumsantrieb angetrieben. As can be seen from FIG. 1, the exemplary embodiment shown is
the carrying
Für einen jeweiligen Tambourwechsel muß die Materialbahn 12 durchtrennt
werden. Dazu umfaßt die Wickelmaschine 10 eine wenigstens ein
Schneidelement 34, 36 (vgl. auch die Figuren 3 bis 6) umfassende
Schneideinrichtung 34. Als Schneidelement 36, 38 kann beispielsweise
ein Wasserstrahl- oder Laserstrahl-Schneidelement vorgesehen sein. Beim
in der Figur 1 dargestellten Ausführungsbeispiel ist die wenigstens ein
Schneidelement 36, 38 umfassende Schneideinrichtung 34 in Bahnlaufrichtung
L vor der Tragtrommel 20 auf der Oberseite der Materialbahn 12
angeordnet. Dabei wird die Materialbahn 12 zwischen der Breitstreckwalze
18 und der Tragtrommel 20 geschnitten.The
Ein jeweiliger Trennvorgang wird vorzugsweise über eine Steuer- und/oder
Regeleinheit 40 so beeinflußt, daß die Materialbahn 12 mittels wenigstens
eines allgemein quer zur Bahnlaufrichtung L verfahrbaren Schneidelements
36, 38 lediglich über einen Teil II der Bahnbreite B durchtrennt
und anschließend wenigstens ein verbleibender Teil III der Materialbahn
12 abgerissen wird (vgl. auch die Figuren 3 bis 5). Die Materialbahn 12
wird somit durch das bzw. die Schneidelemente 36, 38 der Schneideinrichtung
34 lediglich teilweise getrennt, während der verbindende Teil III
abgerissen wird.A respective separation process is preferably carried out via a control and / or
Figur 2 zeigt eine weitere Ausführungsform einer Wickelmaschine 10, die
sich von der Ausführungsform gemäß Figur 1 in erster Linie dadurch unterscheidet,
daß der Spalt zwischen der Tragtrommel 20 und dem vollen
Tambour 14 während des Trennvorgangs geöffnet und die wenigstens ein
Schneidelement 36, 38 umfassende Schneideinrichtung 34 in Bahnlaufrichtung
L hinter der Tragtrommel 20 auf der Unterseite der Materialbahn
12 angeordnet ist. Die Materialbahn 12 wird in diesem Fall somit nicht
nur hinter der Tragtrommel 20, sondern auch von der Unterseite her geschnitten.Figure 2 shows a further embodiment of a winding
Der neue Tambour 14' ist während des Trennvorgangs nicht mehr auf
gleicher Höhe wie die Tragtrommel 20 (vgl. Figur 1), sondern schräg oberhalb
dieser Tragtrommel 20 sowie zwischen dieser und dem abgesetzten
vollen Tambour 14 angeordnet.The new drum 14 'is no longer open during the separation process
same height as the carrying drum 20 (see FIG. 1), but diagonally above

Diese Figur 2 zeigt die Wickelmaschine 10 in einer Betriebsphase unmittelbar
vor einem Tambourwechsel, für den die Materialbahn 12 wieder
durchtrennt werden muß. Die fertige Wickelrolle 16 wurde bereits von der
Tragtrommel 20 entfernt. Sie nimmt ihre Wechselposition ein. In dem Bereich
zwischen der Tragtrommel 20 und der fertigen Wickelrolle 16 ist bereits
der neue, noch leere Tambour 14' bereitgehalten. Es ist auch bereits
ein Wickelspalt 22 zwischen der Tragtrommel 20 und dem neuen Tambour
14' gebildet.FIG. 2 shows the winding
Auch in diesem Fall wird ein jeweiliger Trennvorgang vorzugsweise über
eine Steuer- und/oder Regeleinrichtung 40 wieder so beeinflußt, daß die
Materialbahn 12 mittels wenigstens eines allgemein quer zur Bahnlaufrichtung
L verfahrbaren Schneidelements 36, 38 der Schneideinrichtung
34 lediglich über einen Teil II der Bahnbreite B durchtrennt und anschließend
ein verbleibender Teil III der Materialbahn 12 abgerissen wird (vgl.
auch wieder die Figuren 3 bis 5).In this case too, a respective separation process is preferably carried out
a control and / or regulating
Im übrigen besitzt die Ausführungsform gemäß Figur 2 zumindest im wesentlichen den gleichen Aufbau wie die der Figur 1. Einander entsprechende Teile sind mit gleichen Bezugszeichen versehen. Otherwise, the embodiment according to FIG. 2 has at least essentially the same structure as that of Figure 1. Corresponding to each other Parts have the same reference numerals.
Figur 3 zeigt in schematischer Darstellung ein Ausführungsbeispiel für
einen Schneidvorgang, bei dem zwei Schneidelemente 36, 38 verwendet
werden, die, wie durch die Pfeile angedeutet, von innen nach außen geführt
werden. Dabei werden die beiden Schneidelemente 36, 38 im Abstand
voneinander in einem in Querrichtung beispielsweise mittleren
Bahnbereich I angesetzt und anschließend bei laufender Materialbahn 12
in entgegengesetzter Richtung nach außen verfahren. Die Schnittlinien
enden jedoch im Abstand von den Bahnrändern. Die Materialbahn 12 wird
demzufolge lediglich über einen Teil II der Bahnbreite B geschnitten. Der
zunächst verbleibende und anschließend abzureißende Teil III der Materialbahn
12 umfaßt entsprechend zwei den beiden Bahnrändern benachbarte
Randabschnitte. Der beispielsweise mittlere Bahnabschnitt bildet
eine Zone I, die den Bahnschwanz mit der Bahnspitze zur sicheren
Führung zu dem neuen Tambour 14' verbindet.Figure 3 shows a schematic representation of an embodiment for
a cutting process in which two cutting
Die Breite der durch die beiden Randabschnitte gebildeten Zone III kann beispielsweise größer sein als die des beispielsweise mittleren Bahnabschnitts I.The width of the zone III formed by the two edge sections can For example, be larger than that of the middle section, for example I.
Die Bahnspannung kann bei Erreichen einer vorgebbaren minimalen
Breite der durch die beiden Randabschnitte gebildeten Zone III kurzzeitig
erhöht werden, um diese Zone III abzureißen. Es ist jedoch auch möglich,
die Bahnspannung im Bereich der Schneidelemente 36, 38 so zu wählen,
daß die Zone III bei Erreichen einer vorgebbaren minimalen Zonenbreite
reißt. The web tension can be reached when a predetermined minimum is reached
Width of zone III formed by the two edge sections for a short time
increased to demolish this Zone III. However, it is also possible
to select the web tension in the area of the cutting
Beim vorliegenden Ausführungsbeispiel werden die beiden Schneidelemente
36, 38 so verfahren, daß sich jeweils eine parabelartige, beispielsweise
nach außen gewölbte Schnittlinie ergibt. Die Schneidelemente 36,
38 können beispielsweise jedoch auch so verfahren werden, daß sich jeweils
eine gestrichelt dargestellte S-förmige Schnittlinie ergibt. In der Figur
3 ist der Wendepunkt einer solchen S-förmigen Schnittlinie mit II' angegeben.
Dieser Wendepunkt II' liegt im vorliegenden Fall in einem beispielsweise
mittleren Bereich der betreffenden Schnittlinie.In the present embodiment, the two cutting
Der Schneidvorgang erfolgt bei in Bahnlaufrichtung L bewegter Materialbahn 12.The cutting process takes place with the material web moving in the web running direction L. 12th
Figur 4 zeigt in schematischer Darstellung ein weiteres Ausführungsbeispiel
für einen Schneidvorgang, bei dem wieder zwei Schneidelemente 36,
38 verwendet werden. In diesem Fall werden die beiden Schneidelemente
36, 38 von außen nach innen geführt. Dabei werden die beiden Schneidelemente
36, 38 in einem jeweiligen Abstand von den beiden Bahnrändern
angesetzt und anschließend bei laufender Materialbahn 12 nach innen
verfahren. Im beispielsweise mittleren Bereich der Materialbahn 12 enden
die beiden Schnittlinien im Abstand voneinander.Figure 4 shows a schematic representation of another embodiment
for a cutting process in which two cutting
Der zunächst verbleibende und anschließend abzureißende Teil III der
Materialbahn 12 wird in diesem Fall durch einen in Querrichtung betrachtet
beispielsweise mittleren Bahnabschnitt gebildet. Die beiden
Randbereiche bilden eine Zone I, die den Bahnschwanz mit der Bahnspitze
zur sicheren Führung zum neuen Tambour 14' verbindet. The remaining part of III of the
In this case,
Die Breite der durch den beispielsweise mittleren Bahnabschnitt gebildeten Zone III kann beispielsweise größer sein als die der durch die beiden Randabschnitte gebildeten Zone I.The width of those formed by the middle section, for example Zone III, for example, may be larger than that of the two Edge sections formed zone I.
Die beiden Schneidelemente 36, 38 werden so verfahren, daß die sich
durch diese ergebenden Schnittlinien jeweils eine nach außen gewölbte
parabelartige Form besitzen. Die Schneidelemente 36, 38 können beispielsweise
aber auch so verfahren werden, daß sich jeweils eine gestrichelt
dargestellte S-förmige Schnittlinie ergibt. Der Wendepunkt II' einer
solchen S-förmigen Schnittlinie kann wieder in einem mittleren Bereich
der Schnittlinie liegen.The two
Die Bahnspannung kann bei Erreichen einer vorgebbaren minimalen Breite der durch den beispielsweise mittleren Bahnabschnitt gebildeten Zone III kurzzeitig erhöht werden, um diese Zone III abzureißen. Es ist beispielsweise jedoch auch möglich, die Bahnspannung der Schneidelemente 36, 38 so zu wählen, daß die Zone III bei Erreichen einer vorgebbaren minimalen Zonenbreite reißt.The web tension can be reached when a predetermined minimum is reached Width of that formed by the middle section of the web, for example Zone III can be briefly raised to demolish this Zone III. It is for example, however, the web tension of the cutting elements is also possible 36, 38 to be selected so that zone III is reached when a predefinable minimum zone width tears.
Figur 5 zeigt in schematischer Darstellung ein weiteres Ausführungsbeispiel
für einen Schneidvorgang, bei dem lediglich ein Schneidelement 36
verwendet wird und dieses Schneidelement ausgehend von einem Bahnrand
zu einer dem gegenüberliegenden Bahnrand benachbarten und von
dieser beabstandeten Stelle S geführt wird. Demzufolge wird das Schneidelement
36 an einem Bahnrand angesetzt und anschließend bei laufender
Materialbahn 12 allgemein quer zur Bahnlaufrichtung L so weit verfahren,
daß der zunächst verbleibende und anschließend abzureißende
Teil III der Materialbahn 12 durch einen dem gegenüberliegenden Bahnrand
benachbarten Randabschnitt gebildet wird. Die Materialbahn 12 wird
somit auch in diesem Fall lediglich über einen Teil II der Bahnbreite B geschnitten.
Der verbleibende Teil III wird abgerissen.Figure 5 shows a schematic representation of another embodiment
for a cutting process in which only one cutting
Figur 6 zeigt in schematischer Darstellung ein weiteres Ausführungsbeispiel
für einen Schneidvorgang, bei dem zwei Schneidelemente 36, 38 verwendet
und die beiden Schneidelemente 36, 38 von außen nach innen
geführt werden. Insoweit ist dieses Ausführungsbeispiel vergleichbar mit
dem der Figur 3. Im vorliegenden Fall sind die beiden parabelartigen
Schnittlinien jeweils nach innen gewölbt.Figure 6 shows a schematic representation of another embodiment
for a cutting process in which two cutting
Die Steuer- und/oder Regeleinrichtung 40 kann wenigstens einen Positionssensor
42 (vgl. die Figuren 1 und 2) umfassen, um die Position zumindest
eines Schneidelements 36, 38 zu erfassen.The control and / or regulating
Das Erreichen der vorgebbaren minimalen Breite der durch die beiden
Randabschnitte bzw. durch den beispielsweise mittleren Abschnitt gebildeten
abzureißenden Zone III kann mittels wenigstens eines solchen Positionssensors
42 über die Position des bzw. der Schneidelemente 36, 38
erfaßt werden, die entsprechend mit einem betreffenden Sollwert verglichen
wird. Ein solcher Vergleich kann insbesondere in der Steuer-
und/oder Regeleinrichtung 40 erfolgen.Reaching the minimum width specified by the two
Edge sections or formed by the middle section, for example
Zone III can be demolished by means of at least one
Die Reißspannung kann in Abhängigkeit von der Papiersorte, dem Flächengewicht
und/oder der gewünschten minimalen Breite der durch zwei
Randabschnitte bzw. einen beispielsweise mittleren Bahnabschnitt gebildeten
abzureißenden Zone gewählt und vorzugsweise einem Regler 44 (vgl.
Figuren 1 und 2) vorgegeben werden. Ein solcher Regler 44 kann wieder
Teil der Steuer- und/ oder Regeleinrichtung 40 sein.The tensile strength can vary depending on the type of paper and the basis weight
and / or the desired minimum width by two
Edge sections or a middle section, for example, formed
selected zone and preferably a controller 44 (cf.
Figures 1 and 2) can be specified. Such a
Die Reißspannung kann zumindest teilweise durch Erhöhen des
Drehmoments des vollen Tambours 14 erzeugt werden. Alternativ oder zusätzlich
kann die Reißspannung zumindest teilweise durch Verringern des
Drehmoments des neuen Tambours 14' erzeugt werden. Alternativ oder
zusätzlich ist es auch möglich, die Reißspannung zumindest teilweise
durch Erhöhen des Drehmoments der Tragtrommel 20 zu erzeugen.The tensile stress can be at least partially increased by increasing the
Torque of the
In bestimmten Fällen kann es von Vorteil sein, wenn die Reißspannung
zumindest teilweise durch Erhöhen des Drehmoments der Tragtrommel 20
und durch Erhöhen des Drehmoments des neuen Tambours 14' erzeugt
wird.In certain cases it can be beneficial if the tear tension

Wie sich im Zusammenhang mit dem gestrichelt dargestellten Verlauf A
der Bahnspannung ergibt, kann diese Bahnspannung bei Erreichen einer
vorgebbaren minimalen Breite der abzureißenden Zone III kurzzeitig erhöht
werden, um die Materialbahn 12 abzureißen. Im vorliegenden Fall
wird diese vorgebbare Breite der Zone III zum Zeitpunkt t1 erreicht, zu
dem die Materialbahn 12 über eine entsprechende Zone II geschnitten
wurde. Beim dargestellten Ausführungsbeispiel wurde zu diesem Zeitpunkt
