Description

Die Erfindung betrifft ein Rotationstiefdruckwerk mit den oberbegrifflichen Merkmalen von Anspruch 1 und ein Verfahren zum Warten eines solchen Rotationstiefdruckwerks mit den Merkmalen von Anspruch 7.The invention relates to a rotogravure printing unit with the preamble features of claim 1 and a method for servicing such a rotogravure printing unit having the features of claim 7.

Stand der TechnikState of the art

Eine geläufig eingesetzte Konfiguration eines Tiefdruckwerks ist beispielsweise im Dokument DE 42 42 582 C2 gezeigt. Die Mantelfläche eines Tiefdruckformzylinders, auch weiter unten vereinfacht als Formzylinder oder Druckzylinder bezeichnet, taucht wenigstens teilweise in eine mit Tiefdruckfarbe gefüllte Farbwanne ein, die unterhalb des Tiefdruckformzylinders angeordnet ist. Bei Rotation des Tiefdruckzylinders um seine Symmetrieachse füllen sich die die Wanne passierenden Vertiefungen in der Mantelfläche mit Tiefdruckfarbe. Überschüssige Farbe wird durch wenigstens ein gegen die Mantelfläche angestelltes Rakel abgestreift. In einem im oberen Winkelsektor des Tiefdruckformzylinders liegenden Druckspalt wird die Tiefdruckfarbe auf einen Bedruckstoff übertragen, welcher mittels eines Gegendruckzylinders, nachfolgend auch als Presseur bezeichnet, auf die eingefärbte Mantelfläche des Tiefdruckformzylinders gedrückt wird.A commonly used configuration of a gravure printing unit is, for example, in the document DE 42 42 582 C2 shown. The lateral surface of a gravure printing cylinder, also referred to below simplified as a plate cylinder or printing cylinder, at least partially immersed in a filled with gravure ink pan, which is located below the gravure cylinder. Upon rotation of the gravure cylinder about its axis of symmetry, the wells passing through the well in the lateral surface are filled with gravure ink. Excess paint is stripped off by at least one squeegee against the jacket surface. In a printing gap located in the upper angle sector of the gravure printing cylinder, the gravure ink is transferred to a printing material, which is pressed by means of a counter-pressure cylinder, hereinafter also referred to as impression roller, on the colored outer surface of the gravure printing cylinder.

Die DE 10 2004 009 492 B3 beschreibt ein Tiefdruckwerk mit einem Presseur, bei dem der Presseur gegen einen Formzylinder entlang eines ersten Verfahrweges anstellbar ist. Wird der Presseur von seiner Arbeitsstellung in eine Wartungsstelle verfahren, so sind Presseur und Formzylinder einfach zugänglich und können gewartet, also getauscht bzw. gereinigt werden. Soll die Bedruckstoffbahn während des Abhebens des Presseurs vom Formzylinder nicht angehalten werden und die Bedruckstoffbahn beispielsweise in einem davor oder danach angeordneten Druckwerk oder Bearbeitungsstation weiter bedruckt bzw. bearbeitet werden, so muss während dem Anheben des Presseurs ein Bahnspannungsausgleich erfolgen. So ist es allgemein bekannt und beispielsweise in dem Fachbuch " Kipphan: Handbuch der Printmedien, 2000" (Seite 288 ) beschrieben, für die Bahnspannungsregelung sogenannte Vorspannwerke bzw. Einzugwerke, welche vor dem ersten Druckwerk, oder sogenannte Auszugwerke, welche nach dem letzten Druckwerk angeordnet sind, zu nutzen. Den Bahnspannungsausgleich beim Abheben des Presseurs durch die bekannten Vorrichtungen zum Bahnspannungsausgleich zu regeln wird jedoch als aufwändig, wenig präzise und daher nachteilig erachtet.The DE 10 2004 009 492 B3 describes a gravure printing unit with a impression roller in which the impression roller can be set against a forme cylinder along a first travel path. If the impression roller is moved from its working position to a service point, the impression roller and the form cylinder are easily accessible and can be maintained, ie exchanged or cleaned. If the printing material web is not stopped during the lifting of the impression roller from the forme cylinder and the printing material are further printed or processed, for example, in a before or after arranged printing unit or processing station, so must during the lifting of the impression Web tension compensation done. So it is well known and for example in the textbook " Kipphan: Handbook of Print Media, 2000 "(page 288 ), for the web tension control so-called biasing or retraction works, which before the first printing unit, or so-called pull-out, which are arranged after the last printing unit to use. To regulate the web tension compensation when lifting the impression roller by the known devices for web tension compensation, however, is considered to be laborious, less precise and therefore disadvantageous.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es daher, ein Rotationstiefdruckwerk zu schaffen und ein Verfahren zum Warten eines solchen Rotationstiefdruckwerks zu beschreiben, wobei auch bei angehobenem Presseur in vorgelagerten und nachgelagerten Druckwerken bzw. Bearbeitungsstationen ein registergenaues Bedrucken bzw. Bearbeiten der Bedruckstoffbahn ermöglicht wird und die Nachteile des Standes der Technik zumindest reduziert werden.The object of the present invention is therefore to provide a rotogravure printing unit and to describe a method for servicing such a rotogravure printing unit, wherein a register-accurate printing or processing of the printing material web is made possible even with raised impression roller in upstream and downstream printing units or processing stations and the disadvantages of At least reduced prior art.

Gelöst wird diese Aufgabe durch ein Rotationstiefdruckwerk für eine Druckmaschine zum Bedrucken eines bahnförmigen Bedruckstoffs, wobei das Rotationstiefdruckwerk einen Formzylinder, eine Farbauftragseinrichtung, einen Presseur und mindestens zwei Leitrollen zum Führen des Bedruckstoffes aufweist. Die erste Leitrolle ist dabei - in Bahnlaufrichtung gesehen - stromaufwärtig und die zweite Leitrolle - in Bahnlaufrichtung gesehen - stromabwärtig des Presseurs angeordnet.
Erfindungsgemäß besitzt das Rotationstiefdruckwerk einen dem Formzylinder zugeordneten Servoantrieb zum Antreiben des Formzylinders und einen dem Presseur zugeordneten Aktuator zur Höhenveränderung des Presseurs von einer Arbeitsstellung in eine deutlich beabstandete und leichter zugängliche Wartungsstellung. Auch dem Presseur kann ein Servoantrieb zum Antreiben des Presseurs zugeordnet sein. Insbesondere bei einem dünnen und/oder empfindlichen Bedruckstoff kann so der Presseur aktiv angetrieben werden und läuft nicht nur passiv mit. Zusätzlich ist in dem Rotationstiefdruckwerk selbst eine aktuatorisch ansteuerbare Einrichtung zum Bahnspannungsausgleich vorgesehen, um die Bahnspannung in diesem Rotationstiefdruckwerk konstant zu halten. Durch diese Ausgestaltung ist es in vorteilhafter Weise möglich, während dem Abheben des Presseurs vom Formzylinder unmittelbar im Rotationstiefdruckwerk selbst einen Bahnspannungsausgleich durchzuführen, so dass das Anheben des Presseurs keine Auswirkungen auf die Bahnspannung der Bedruckstoffbahn in vorgeordneten oder nachgeordneten Stationen hat.
In der Wartungsstellung wird die Wartung der Zylinder im weiteren Sinn ermöglicht, d.h. Reinigen, Reparieren, Umrüsten, Austauschen.This object is achieved by a rotogravure printing unit for a printing machine for printing a web-shaped substrate, wherein the rotogravure printing unit has a forme cylinder, an inking device, a impression roller and at least two guide rollers for guiding the printing material. The first guide roller is - seen in the web running direction - upstream and the second guide roller - as seen in the web running direction - arranged downstream of the impression.
According to the invention, the rotogravure printing unit has a servo drive assigned to the forme cylinder for driving the forme cylinder and an actuator assigned to the impression roller for changing the height of the impression roller from a working position to a clearly spaced and easily accessible maintenance position. The impression roller can also be assigned a servo drive for driving the impression roller. In particular, in the case of a thin and / or sensitive printing material, the impression roller can thus be actively driven and not only passes on passively. In addition, an actuatable device for web tension compensation is provided in the rotogravure printing unit itself in order to keep the web tension constant in this rotogravure printing unit. Through this Embodiment, it is possible in an advantageous manner, during the lifting of the impression from the forme cylinder directly in the rotogravure even perform a web tension compensation, so that the lifting of the impression has no effect on the web tension of the printing material in upstream or downstream stations.
In the maintenance position, cylinder maintenance is possible in a broader sense, ie cleaning, repair, changeover, replacement.

In vorteilhafter Weiterbildung des erfindungsgemäßen Rotationstiefdruckwerks sind die erste und zweite Leitrolle zwischen dem Höhenniveau des Presseurs in seiner Arbeitsstellung und dem Höhenniveau des Presseurs in seiner Wartungsstellung angeordnet. Wenn der Presseur von seiner Arbeitsstellung in seine Wartungsstellung angehoben wird, verläuft die Bedruckstoffbahn direkt von der ersten zur zweiten Leitrolle und wird jeweils entlang eines Teilumfangs einer jeweiligen Leitrolle durch diese geführt.In an advantageous embodiment of the rotogravure printing unit according to the invention, the first and second guide rollers are arranged between the height level of the impression roller in its working position and the height level of the impression roller in its maintenance position. When the impression roller is raised from its working position to its maintenance position, the printing material web runs directly from the first to the second guide roller and is guided in each case along a partial circumference of a respective guide roller through this.

In einer besonders vorteilhaften und daher bevorzugten Ausführungsform ist der dem Presseur zugeordnete Aktuator als Elektromotor, insbesondere als Servomotor, ausgeführt zum Verschieben des Presseurs entlang einer Führung, welche insbesondere vertikal ausgerichtet ist. Die Ausführung des Aktuators als Elektromotor ermöglicht zum einen eine sehr genaue Wegführung und zum anderen die Rückmeldung einer jeweils aktuellen IstPosition.In a particularly advantageous and therefore preferred embodiment, the actuator assigned to the impression roller is designed as an electric motor, in particular as a servomotor, for displacing the impression roller along a guide, which is in particular vertically aligned. The design of the actuator as an electric motor allows for a very accurate routing and on the other hand, the feedback of each current IstPosition.

In einer vorteilhaften Weiterbildung des erfindungsgemäßen Rotationstiefdruckwerks besitzt die Einrichtung zum Bahnspannungsausgleich eine weitere Leitrolle und einen Elektromotor zum Verschieben der weiteren Leitrolle entlang einer Führung. Diese Führung kann dabei insbesondere horizontal ausgerichtet sein.In an advantageous embodiment of the rotogravure printing unit according to the invention, the device for web tension compensation has a further guide roller and an electric motor for displacing the further guide roller along a guide. This guide can be oriented horizontally in particular.

In einer besonders vorteilhaften und daher bevorzugten Variante des erfindungsgemäßen Rotationstiefdruckwerks sind die Achsen der weiteren Leitrolle und des Presseurs in seiner Arbeitsstellung in Betrieb des Rotationstiefdruckwerks in einer vertikalen Ebene angeordnet. In anderen Worten: im Betrieb des Rotationstiefdruckwerks befindet sich die weitere Leitrolle vertikal oberhalb des Presseurs. Die erste Leitrolle, zweite Leitrolle, weitere Leitrolle und der Presseur als auch der Formzylinder sind spiegelsymmetrisch zu einer Mittelebene durch Formzylinder und Presseur, also zur zuvor genannten vertikalen Ebene angeordnet. Dadurch wird in vorteilhafter Weise ermöglicht, dass das Rotationstiefdruckwerk laufrichtungsunabhängig ist. Das heißt, die Bedruckstoffbahn kann nach Anpassung des Bahnlaufs in beide mögliche Richtungen durch das Rotationstiefdruckwerk hindurch und in diesem bearbeitet werden. Dies ist besonders dann von Bedeutung, wenn die Bedruckstoffbahn beidseitig bedruckt werden soll, d.h. in einem ersten Durchlauf auf der Schöndruckseite und in einem zweiten Durchlauf in umgekehrter Bahnlaufrichtung von der Widerdruckseite.In a particularly advantageous and therefore preferred variant of the rotogravure printing unit according to the invention, the axes of the further guide roller and the impression roller in its working position in operation of the rotogravure printing unit are arranged in a vertical plane. In other words: during operation of the rotogravure printing unit, the further guide roller is located vertically above the impression roller. The first guiding role, second guiding role, another idler roller and the impression roller as well as the forme cylinder are arranged mirror-symmetrically to a center plane through the form cylinder and impression roller, ie to the aforementioned vertical plane. This advantageously makes it possible for the rotogravure printing unit to be independent of the direction of travel. That is, the substrate web can be processed by the rotogravure printing unit in and through this after adjustment of the web run in both possible directions. This is particularly important if the substrate web is to be printed on both sides, ie in a first pass on the recto printing side and in a second pass in the reverse web direction from the counterpressure side.

Die Erfindung betrifft auch eine Schmalbahn-Rotationsdruckmaschine mit einer Mehrzahl von Druckwerken, wobei mindestens eines der Druckwerke wie obenstehend ausgeführt ist. Zusätzlich kann die Schmalbahn-Rotationsdruckmaschine ein aus dem Stand der Technik bekanntes Einzugwerk und Auszugwerk besitzen.The invention also relates to a narrow-web rotary printing press with a plurality of printing units, wherein at least one of the printing units is designed as described above. In addition, the narrow-web rotary printing press may have a known from the prior art retraction and extraction.

Weiter betrifft die Erfindung ein Verfahren zum Warten eines wie obenstehend beschriebenen Rotationstiefdruckwerks, wobei der Presseur von dem Formzylinder abgehoben wird, so dass beide für Wartungsarbeiten zugänglich werden. Zugänglich werden meint in diesem Zusammenhang, dass der Maschinenbediener Reinigungsarbeiten an Presseur oder Formzylinder durchführen kann, dass Presseur oder Formzylinder ausgetauscht werden können, dass Tiefdrucksleeves auf den Tiefdruckzylinder aufgeschoben werden können, etc. Während dem Abheben des Presseurs durch eine Verschiebebewegung von seiner Arbeitsstellung in seine Wartungsstellung wird dabei eine Einrichtung zum Bahnspannungsausgleich angesteuert, derart, dass die Bahnspannung annähernd konstant gehalten wird und wobei der bahnförmige Bedruckstoff nicht angehalten wird. Dadurch wird in vorteilhafter Weise ermöglicht, dass vorgelagerte und nachgelagerte Druckwerke bzw. Bearbeitungsstationen während dem Warten des Rotationstiefdruckwerks weiter arbeiten können.Furthermore, the invention relates to a method for servicing a rotogravure printing unit as described above, wherein the impression roller is lifted off the forme cylinder, so that both are accessible for maintenance. Becoming accessible in this context means that the machine operator can perform cleaning work on impression roller or forme cylinder, that impression roller or forme cylinder can be exchanged, that intaglio sleeves can be pushed onto the gravure cylinder, etc. During lifting of the impression roller by a displacement movement from its working position into its Maintenance position while a device for web tension compensation is controlled, such that the web tension is kept approximately constant and wherein the web-shaped substrate is not stopped. This advantageously makes it possible for upstream and downstream printing units or processing stations to continue working while the rotogravure printing unit is being maintained.

In vorteilhafter Weiterbildung des erfindungsgemäßen Verfahrens, nämlich dann, wenn dem Presseur ein steuerbarer Elektromotor und der Einrichtung zum Bahnspannungsausgleich ebenfalls ein steuerbarer Elektromotor zugeordnet sind, werden die Elektromotoren von einer gemeinsamen Steuereinheit angesteuert, derart, dass die Längung der Bedruckstoffbahn durch das Anheben des Presseurs von der Einrichtung zum Bahnspannungsausgleich zeitgleich ausgeglichen wird. Entsprechende Ansteuerungsregeln können in der Steuereinheit hinterlegt sein.In an advantageous embodiment of the method according to the invention, namely when the impression roller, a controllable electric motor and the device for web tension compensation are also assigned a controllable electric motor are the electric motors driven by a common control unit, such that the elongation of the printing material is offset by the lifting of the impression of the device for web tension compensation at the same time. Corresponding control rules can be stored in the control unit.

Einander entsprechende Elemente und Bauteile sind in den Figuren mit gleichen Bezugszeichen versehen.Corresponding elements and components are provided in the figures with the same reference numerals.

In Fig. 1a ist ein erfindungsgemäßes Rotationstiefdruckwerk 10 dargestellt, in welchem eine Bedruckstoffbahn 100 bedruckt wird. Die Tragstruktur des Druckwerks 10 wird durch einen Druckwerksständer 1 gebildet. Wie durch den Pfeil b dargestellt, durchläuft die Bedruckstoffbahn 100 das Rotationstiefdruckwerk 10 dabei wie folgt: von einem nicht dargestellten vorangehenden Druckwerk oder einer nicht dargestellten vorangehenden Bearbeitungsstation läuft die Bedruckstoffbahn 100 in das Tiefdruckwerk 10 ein, wird durch eine erste Leitrolle 5 zwischen Tiefdruckzylinder 3 und Presseur 2 hindurch geführt, wo die Bedruckstoffbahn 100 bedruckt wird, nachfolgend von einer zweiten Leitrolle 5 geführt und dann über die weitere Leitrolle 41 der Einrichtung zum Bahnspannungsausgleich 4 geführt, bevor sie das Tiefdruckwerk 10 verlässt und zu einem nachgeordneten, nicht dargestellten weiteren Druckwerk oder einer nachgeordneten, nicht dargestellten Bearbeitungsstation weiter transportiert wird. In der Darstellung von Fig. 1a befindet sich der Presseur 2 in seiner Arbeitsstellung und auf einem Höhenniveau HA, während sich die weitere Leitrolle 41 in ihrer Nullstellung N befindet. Die weitere Leitrolle 41 als auch der Presseur 2 sind in einer vertikalen Ebene VE angeordnet.
Angetrieben wird der Formzylinder 3 von einem Servomotor 7, welcher sich nicht sichtbar hinter der Zeichnungsebene befindet. In den Figuren ist daher nur die Antriebsachse des Servomotors 7 angedeutet. Auch dem Presseur 2 kann ein Servomotor zu dessen Antrieb zugeordnet sein (nicht dargestellt).In Fig. 1a an inventive rotogravure printing unit 10 is shown, in which a printing substrate 100 is printed. The support structure of the printing unit 10 is formed by a printing unit stand 1. As shown by the arrow b, the passes through Substrate web 100 the rotogravure printing unit 10 thereby as follows: from a preceding printing unit not shown or a preceding processing station, the printing substrate 100 runs in the gravure printing unit 10, is passed through a first guide roller 5 between gravure cylinder 3 and impression roller 2, where the printing substrate 100th is printed, subsequently guided by a second guide roller 5 and then passed over the further guide roller 41 of the device for web tension compensation 4 before it leaves the gravure printing unit 10 and is transported to a downstream, not shown further printing unit or a downstream processing station, not shown. In the presentation of Fig. 1a the impression roller 2 is in its working position and at a height level HA, while the further guide roller 41 is in its zero position N. The further guide roller 41 and the impression roller 2 are arranged in a vertical plane VE.
The forme cylinder 3 is driven by a servomotor 7, which is not visible behind the plane of the drawing. In the figures, therefore, only the drive axis of the servomotor 7 is indicated. Also, the impression roller 2 may be associated with a servomotor to its drive (not shown).

Soll nun das Tiefdruckwerk 10 gewartet oder für einen nachfolgenden Auftrag umgerüstet werden, so wird der Presseur 2 entlang einer vertikalen Führung durch einen Aktuator 8 vom Tiefdruckzylinder 3 abgehoben. Der Presseur 2 wird dabei von seinem Höhenniveau der Arbeitsstellung HA auf sein Höhenniveau in Wartungsstellung HW angehoben. Der angehobene Zustand ist dabei in Fig. 1b dargestellt: Wie aus der Figur ersichtlich wird, wurde zeitgleich während dem Abheben des Presseurs 2 die Einrichtung zum Bahnspannungsausgleich 4 aktiviert, nämlich wurde die weitere Leitrolle 41 durch eine Ausgleichsbewegung a von ihrer Position in der vertikalen Ebene VE leicht nach rechts in eine Ausgleichsstellung A verschoben. Das heißt, die Verkürzung der Bahnlaufstrecke durch das Anheben des Presseurs 2 wird durch die Ausgleichsbewegung a, welche eine Längung der Bahnlaufstrecke bewirkt, ausgeglichen und die Bahnspannung konstant gehalten. Die Ansteuerung des dem Presseur 2 zugeordneten Aktuators 8 und des der weiteren Leitrolle 41 zugeordneten Elektromotors 42 wird von einer gemeinsamen Steuereinheit 9 ausgeführt. In dieser Steuereinheit 9 können entsprechende Zeit-Weg-Verläufe sowohl für den Aktuator 8 als auch für den Elektromotor 42 hinterlegt sein.If now the gravure printing unit 10 is to be serviced or converted for a subsequent order, the impression roller 2 is lifted off the gravure cylinder 3 along a vertical guide by an actuator 8. The impression roller 2 is thereby raised from its height level of the working position HA to its height level in the maintenance position HW. The raised state is in Fig. 1b As is apparent from the figure, at the same time during the lifting of the impression roller 2, the device for web tension compensation 4 was activated, namely, the further guide roller 41 was moved by a compensating movement a from its position in the vertical plane VE slightly to the right in a balancing position A. , That is, the shortening of the web path by lifting the impression roller 2 is compensated by the compensating movement a, which causes an elongation of the web running path, and the web tension is kept constant. The control of the pressurizer 2 associated actuator 8 and the further idler 41 associated electric motor 42 is performed by a common control unit 9. In this control unit 9 corresponding time-path curves for both the actuator 8 and for the electric motor 42 may be deposited.

Durch das Anheben des Presseurs 2 wird es dem Maschinenbediener ermöglicht, Wartungs- und Umrüstarbeiten an dem Tiefdruckwerk 19 durchzuführen. Dazu wurde gemäß der Darstellungen von Fig. 1b das Rakel der Farbauftragseinrichtung 6 vom Tiefdruckzylinder 3 abgestellt, so dass auch der Tiefdruckzylinder 3 getauscht werden kann.By lifting the impression roller 2, it is possible for the machine operator to carry out maintenance and retooling work on the gravure printing unit 19. This was done according to the representations of Fig. 1b the squeegee of the inking device 6 turned off by the gravure cylinder 3, so that even the gravure cylinder 3 can be exchanged.

Fig. 2 zeigt das Rotationstiefdruckwerk 10 im Betrieb. Im Gegensatz zur Darstellung von Fig. 1a wird ein Tiefdruckzylinder 3 mit größerem Durchmesser eingesetzt. Der erforderliche Bahnspannungsausgleich, welcher aufgrund des größeren Tiefdruckzylinders 3 erforderlich ist, wird dabei von der Einrichtung zum Bahnspannungsausgleich 4 realisiert. Die weitere Leitrolle 41 wurde dazu von ihrer Nullstellung N durch eine Ausgleichsbewegung a in eine Ausgleichsstellung A leicht nach rechts verschoben. Fig. 2 shows the rotogravure printing unit 10 in operation. In contrast to the representation of Fig. 1a a gravure cylinder 3 is used with a larger diameter. The required web tension compensation, which is required due to the larger gravure cylinder 3, is realized by the device for web tension compensation 4. The further guide roller 41 has been moved from its zero position N by a compensating movement a in a balancing position A slightly to the right.

Fig. 3 zeigt das Rotationstiefdruckwerk 10 im Betrieb. Im Gegensatz zur Darstellung von Fig. 1a wurde die Laufrichtung b der Bedruckstoffbahn 100 umgekehrt. Dies ist auf Grund der symmetrischen Anordnung der Walzen 4, 5 und der Zylinder 2, 3 in der Nullstellung N problemlos möglich. Fig. 3 shows the rotogravure printing unit 10 in operation. In contrast to the representation of Fig. 1a the direction of travel b of the substrate web 100 was reversed. This is easily possible due to the symmetrical arrangement of the rollers 4, 5 and the cylinder 2, 3 in the neutral position N.

In Fig. 4 ist die Einrichtung zum Bahnspannungsausgleich 4 im Detail dargestellt: Die weitere Leitrolle 41 kann entlang einer horizontalen Führung 43 verschoben werden, sodass diese eine Ausgleichsbewegung a bewirkt. Die Verschiebung der weiteren Leitrolle 41 erfolgt durch einen Elektromotor 42, dessen Rotationsbewegung über ein Getriebe 44 mit Spindeln in eine Linearbewegung gewandelt und auf beide Lager der weiteren Leitrolle 41 übertragen wird.In Fig. 4 the device for web tension compensation 4 is shown in detail: The further guide roller 41 can be moved along a horizontal guide 43 so that it causes a compensating movement a. The displacement of the further guide roller 41 is effected by an electric motor 42, the rotational movement of which is converted by a gear 44 with spindles into a linear movement and is transmitted to both bearings of the further guide roller 41.
