Description

Die vorstehende Erfindung betrifft eine Vorrichtung zur Registereinstellung in Laengs- als auch in Querrichtung einer zu bedruckenden Bahn gegenueber dem Druckzylinder einer Rotationsdruckmaschine.The above invention relates to a device for register adjustment in the longitudinal as well as in the transverse direction of a web to be printed relative to the printing cylinder of a rotary printing press.

Es ist bekannt, dass Rotationsdruckmaschinen Einrichtungen fuer die Registereinstellung zwischen zwei Farbwerken aufweisen.It is known that rotary printing presses have devices for register adjustment between two inking units.

Die bekannten Einrichtungen dieser Art bestehen im wesentlichen aus einer Fuehrungsrolle fuer die Papierbahn, die in den Seitenteilen des Druckelementes montiert ist und sich ueblicherweise im Inneren einer Anzahl weiterer horizontal angeordneter Fuehrungsrollen befinden, die fuer andere Aufgaben vorgesehen sind. Die Fuehrungsrolle der in Laengsrichtung der zu bedruckenden Bahn wirksam werdenden Registereinstellvorrichtung ist hoehenverstellbar gegenueber dem Gestell der Druckeinheit gelagert.The known devices of this type consist essentially of a guide roller for the paper web, which is mounted in the side parts of the pressure element and are usually located inside a number of further horizontally arranged guide rollers, which are provided for other tasks. The guide roller of the register adjustment device, which becomes effective in the longitudinal direction of the web to be printed, is mounted such that it can be adjusted in height relative to the frame of the printing unit.

Um in den bekannten Maschinen auch eine Einstellung des Querregisters zu ermoeglichen, ist es bekannt, im Inneren des Druckelementes eine weitere Fuehrungsrolle der Papierbahn vorzusehen. Diese Fuehrungsrolle fuehrt fuer die Registereinstellung eine Schwenkbewegung um eine Achse durch, die senkrecht zur Laengsachse der Fuehrungsrolle angeordnet ist.In order to enable adjustment of the cross register in the known machines, it is known to provide a further guide roller of the paper web inside the printing element. For the register setting, this guide roller carries out a pivoting movement about an axis which is arranged perpendicular to the longitudinal axis of the guide roller.

Es ist verstaendlich, dass die Notwendigkeit, im Inneren des Maschinengestells eines Druckelementes einer Rotationsdruckmaschine neben mehreren Fuehrungsrollen, die mit anderen Zylindern oder Rollen zusammenarbeiten, auch zusaetzliche Stellvorrichtungen bekannter Ausfuehrung vorzusehen, die Anordnung und Montage der Registereinstellvorrichtung schwierig werden lassen, besonders wenn man beruecksichtigt, dass der im Inneren eines Druckelementes zur Verfuegung stehende Raum aeusserst beschraenkt ist.It is understandable that the need to provide additional adjusting devices of known design in the interior of the machine frame of a printing element of a rotary printing press, in addition to several guide rollers which work together with other cylinders or rollers, can make the arrangement and assembly of the register adjusting device difficult, especially when taking into account that the space available inside a pressure element is extremely limited.

Des weiteren ist die Durchfuehrung von Instandhaltungs- oder Reparaturarbeiten im Inneren eines Druckelementes nicht einfach, einmal weil die Einrichtungen fuer die Registereinstellung in Laengsrichtung als auch in Querrichtung, im Inneren des Druckelementes zwischen zusaetzlich erforderlichen Rollen oder Zylindern angeordnet sind und die Vorrichtung zum Einstellen des Registers in Laengsrichtung mechanisch und funktionell von der Rolle fuer die Einstellung des Querregisters getrennt angeordnet ist. Es sei noch darauf hingewiesen, dass die Montage der bekannten Einrichtung, deren Instandhaltung, sowie anfallende Reparaturarbeiten oder Montagevorgaenge, z.B. fuer den Austausch der Vorrichtungen, nur aeusserst aufwendig durchfuehrbar sind.Furthermore, performing maintenance or repair work inside a pressure element is not easy, firstly because the devices for register adjustment in the longitudinal direction as well as in the transverse direction, inside the pressure element, are arranged between additionally required rollers or cylinders and the device for adjusting the register mechanically and functionally from the roll in the longitudinal direction is arranged separately for setting the cross register. It should also be pointed out that the assembly of the known device, its maintenance, as well as any repair work or assembly operations, for example for the replacement of the devices, can only be carried out with great effort.

Eine in der horizontalen Ebene in der Querrichtung schwenkbare Vorrichtung zur Führung von laufenden Materialbahnen, ist aus der US-A-3583615 bekannt.A device for guiding running material webs, which can be pivoted in the transverse direction in the horizontal plane, is known from US-A-3583615.

Es ist Aufgabe der vorstehenden Erfindung, die Nachteile des Standes der Technik zu vermeiden und eine einzige kompakte und modular ausgebildete Vorrichtung, sowohl Euer die Einstellung des Laengsregisters als auch fuer die Einstellung des Querregisters bei einer zu bedruckenden Bahn gegenueber einem Druckzylinder, vorzuschlagen und zu ermoeglichen, dass die Einstellung des Laengsregisters als auch die Einstellung des Querregisters unter Zuhilfenahme einer einzigen Fuehrungsrolle fuer die zu bedruckende Bahn durchfuehrbar ist und dass es ferner moeglich wird, die Registereinstellvorrichtung als einzige kompakte Baueinheit auf dem Gestell eines Druckelements anzuordnen und dadurch eine einfache und ungehinderte Zugaenglichkeit zur Durchfuehrung von Instandhaltungsarbeiten, Einstellarbeiten und Reparaturarbeiten zu ermoeglichen und bei Auftreten schwerwiegender Stoerungen die Moeglichkeit zu eroeffnen, die gesamte Registereinstellvorrichtung dank ihres kompakten und modularen Aufbaus innerhalb kurzer Zeit gesamthaft abzubauen und die Montage einer Ersatzvorrichtung mit einer neuen Registereinstellvorrichtung zu ermoeglichen und dadurch die Stillstandszeit der Druckmaschine wesentlich einzuschraenken.It is an object of the above invention to avoid the disadvantages of the prior art and to propose and enable a single compact and modular device, both your setting of the longitudinal register and for the setting of the transverse register in the case of a web to be printed relative to a printing cylinder that the setting of the longitudinal register and the setting of the transverse register can be carried out with the aid of a single guide roller for the web to be printed, and that it also becomes possible to arrange the register setting device as a single compact unit on the frame of a printing element and thereby a simple and unobstructed access for carrying out maintenance work, adjustment work and repair work and, in the event of serious malfunctions, the possibility to open the entire register setting device thanks to its compact and modular structure dismantled in a short time and the assembly of a To enable replacement device with a new register setting device and thereby significantly reduce the downtime of the printing press.

Die erfindungsgemaesse Aufgabe wird dadurch geloest, dass die Vorrichtung fuer die Registereinstellung aus seitlichen Lagerungen besteht, die mit dem Gestell des Druckelementes verbunden sind, dass zwischen diesen Lagerungen ein Rahmen angeordnet ist, der einen Fuehrungszylinder aufnimmt, der gesteuert in einer vertikalen Ebene verschiebbar ist, dass der Rahmen einen weiteren Fuehrungszylinder in ortsfester Lage aufnimmt und dass zwischen dem Rahmen zur Aufnahme der Fuehrungszylinder und den seitlichen Lagerungen Schwenklager angeordnet sind und der Rahmen mit einer steuerbaren Schwenkvorrichtung verbunden ist.The object according to the invention is achieved in that the device for register adjustment consists of lateral bearings which are connected to the frame of the pressure element, that a frame is arranged between these bearings, which receives a guide cylinder which can be displaced in a controlled manner in a vertical plane, that the frame receives a further guide cylinder in a fixed position and that pivot bearings are arranged between the frame for receiving the guide cylinders and the lateral bearings and the frame is connected to a controllable pivoting device.

Mit einer Vorrichtung dieser Art wird eine Einrichtung zur Registereinstellung geschaffen, die kompakte, baukastenartige Bauform aufweist und die Moeglichkeit eroeffnet, den zwei Fuehrungsrollen fuer die Registereinstellung sowohl eine gesteuerte Laengsbewegung als auch eine gesteuerte Schwenkbewegung zu verleihen und dadurch die Moeglichkeit zu schaffen, dass unter Zuhilfenahme von nur zwei Fuehrungsrollen die Registereinstellung sowohl in Laengsrichtung als auch in Querrichtung zwischen zwei Farbpunkten erfolgen kann. Der Erfindungsgegenstand wird nun genauer beschrieben und anhand eines Ausfuehrungsbeispieles in den Zeichnungen dargestellt. Es zeigen:

  • Fig. 1 in perspektivischer Darstellung die neue Vorrichtung fuer die Registereinstellung in Verbindung mit den Seitenwaenden eines Druckelements;
  • Fig. 2 die erfindungsgemaesse Vorrichtung schematisch in Seitenansicht zur Darstellung der Vorrichtung fuer die Einstellung des Registers in Laengsrichtung, und

With a device of this type, a device for register adjustment is created, which has a compact, modular design and opens up the possibility of imparting both a controlled longitudinal movement and a controlled pivoting movement to the two guide rollers for register adjustment and thereby creating the possibility of using this The register can be adjusted between two color dots in both the longitudinal and transverse directions using only two guide rollers. The subject of the invention is now described in more detail and shown in the drawings using an exemplary embodiment. Show it:
  • Figure 1 is a perspective view of the new device for register setting in connection with the side walls of a printing element.
  • Fig. 2 shows the device according to the invention schematically in side view to show the device for adjusting the register in the longitudinal direction, and
  • Fig. 3 shows schematically in a plan view a part of the inventive device for displaying the devices for register adjustment in the transverse direction.

Wie der Fig. 1 zu entnehmen ist, besteht die gesamthaft mit 1 gekennzeichnete Vorrichtung zur Registereinstellung aus zwei seitlichen Lagerungen 2 und 3, die fest mit den Wandteilen eines Druckelementes (nicht dargestellt) verbunden sind. Zwischen den Lagerungen 2 und 3 ist ein stabiler Rahmen angeordnet, der gesamthaft mit 4 gekennzeichnet ist.As can be seen from FIG. 1, the device for register adjustment, identified overall by 1, consists of two lateral bearings 2 and 3, which are fixedly connected to the wall parts of a pressure element (not shown). Between the bearings 2 and 3, a stable frame is arranged, which is identified overall by 4.

Der Rahmen 4 besteht aus zwei Streben 5 und 6, die parallel zu den Lagerungen 2 und 3 angeordnet sind und untereinander mittels Querstreben 7 und 8 verbunden sind. Parallel zu den Querstreben 7 und 8 sind Rollen 9 und 10 angeordnet, die als Fuehrungsrollen fuer die Papierbahn oder ein anderes zu bedruckendes Material, das ueblicherweise in Rotationsdruckmaschinen zum Einsatz kommen kann, dienen. Die Fuehrungsrollen 9 und 10 sind frei drehbar im Rahmen 4 gelagert und erlauben der Papierbahn 11 eine ungehinderte Bewegung in Richtung des Pfeiles f. Die vordere Fuehrungsrolle 9 ist an beiden Enden frei drehbar in einem Lagerblock 12 gelagert. Jeder Lagerblock 12 ist verschiebbar von einer senkrecht angeordneten Fuehrungssaeule 13 aufgenommen, ferner steht der Lagerblock 12 mit einer Verstellschraube 14 in Wirkverbindung. Das obere und untere Ende einer jeden Fuehrungssaeule 13, sowie der zugeordneten Verstellschraube 14 sind von Halteplatten 15 und 16 aufgenommen. Die Halteplatten sind mit den Streben 5 und 6 des Rahmens 4 verbunden. Eine weitere Beschreibung dieser Bauteile ist dem folgenden Text zu entnehmen:
Auch die rueckwaertig angeordnete Fuehrungsrolle 10 ist in Aufnahmeplatten 18 und 19 gelagert.The frame 4 consists of two struts 5 and 6, which are arranged parallel to the bearings 2 and 3 and are interconnected by means of cross struts 7 and 8. Parallel to the cross struts 7 and 8 are arranged rollers 9 and 10, which serve as guide rollers for the paper web or another material to be printed, which can usually be used in rotary printing machines. The Guide rollers 9 and 10 are freely rotatable in the frame 4 and allow the paper web 11 an unimpeded movement in the direction of arrow f. The front guide roller 9 is freely rotatably supported in a bearing block 12 at both ends. Each bearing block 12 is slidably received by a vertically arranged guide column 13, and the bearing block 12 is operatively connected to an adjusting screw 14. The upper and lower ends of each guide column 13 and the associated adjusting screw 14 are received by holding plates 15 and 16. The holding plates are connected to the struts 5 and 6 of the frame 4. A further description of these components can be found in the following text:
The backward arranged guide roller 10 is also mounted in receiving plates 18 and 19.

Der Fig. 1 kann entnommen werden, dass unter Zuhilfenahme von Hebegetrieben 20, die unterschiedliche Ausbildung aufweisen koennen, der Rahmen 4 mit einer Betaetigungsvorrichtung 21 verbunden ist, die mit einer Antriebsschraube 22 wirkverbunden ist, wobei die Antriebsschraube 22 ueber einen steuerbaren Motor 23 antreibbar ist. Diese Vorrichtung ist gesamthaft an der Aussenseite der Lagerung 3 angebracht.1 that the frame 4 is connected to an actuating device 21, which is operatively connected to a drive screw 22, with the aid of lifting gears 20, which can have different designs, the drive screw 22 being drivable via a controllable motor 23 . This device is attached overall to the outside of the bearing 3.

Die Lagerplatten 16 und 17 sowie 18 und 19 bilden mit plattenfoermigen Bauteilen 24,25 und 26,27, die mit den Lagerungen 2 und 3 verbunden sind, Kugel- oder Rollenlager, um somit eine genaue Bewegung des Rahmens 4 gegenueber den Lagerungen 2 und 3 zu ermoeglichen. Zu diesem Zweck werden zwischen den Lagerplatten 16,25,17,24,18,26 und 19,27 Gleitbahnen 30 gebildet. Zwischen den Bahnen 30 sind Abrollmittel, z.B. Kugeln oder Rollen 31 eingesetzt. Auch wenn aufgrund zeichnerischer Vereinfachungen die Ablaufbahnen geradlinig dargestellt sind, ist darauf hinzuweisen, dass diese Abrollbahnen 30 bogenfoermigen Verlauf mit sehr grossem Bogenradius haben, wodurch eine genaue Schwenkbewegung des Rahmens 4 in einer horizontalen Ebene gegenueber den seitlichen Lagerungen 2 und 3 moeglich wird.The bearing plates 16 and 17 and 18 and 19 form with plate-shaped components 24, 25 and 26, 27, which are connected to the bearings 2 and 3, ball or roller bearings, in order to enable an exact movement of the frame 4 relative to the bearings 2 and 3. For this purpose, slideways 30 are formed between the bearing plates 16, 25, 17, 24, 18, 26 and 19, 27. Rolling means, for example balls or rollers 31, are inserted between the webs 30. Even if, due to the simplification of the drawings, the runways are shown in a straight line, it should be pointed out that these runways 30 have an arcuate shape with a very large radius of curvature, as a result of which a precise pivoting movement of the frame 4 in a horizontal plane relative to the lateral bearings 2 and 3 is possible.

Die zu bedruckende Bahn 11, die in Richtung des Pfeiles f laeuft, erreicht nach Ueberlaufen der Fuehrungsrolle 10 die vordere Rolle 9. Jeder Endzapfen des Zylinders 9 ist von einem Lagerblock 12 aufgenommen, und jeder Lagerblock 12 ist verschiebbar in Vertikalrichtung auf einer Fuehrungssaeule 13 angeordnet, die mit den Halteplatten 15 und 16 verbunden ist.The web 11 to be printed, which runs in the direction of the arrow f, reaches the front roller 9 after the guide roller 10 overflows , which is connected to the holding plates 15 and 16.

Mit den Halteplatten 15 und 16 ist ferner eine Antriebsschraube 14 verbunden, die mit dem Lagerblock 12 in Wirkverbindung steht. Ein Ende der Antriebsschraube 14 ist mit der Antriebswelle (nicht dargestellt) eines Reduziergetriebes 32 wirkverbunden, wobei die Antriebswelle 33 des Getriebes mit einem Antriebsmotor 34 wirkverbunden ist.A drive screw 14 is also connected to the holding plates 15 and 16 and is operatively connected to the bearing block 12. One end of the drive screw 14 is one with the drive shaft (not shown) Reduction gear 32 is operatively connected, the drive shaft 33 of the transmission being operatively connected to a drive motor 34.

In vorteilhafter Weise ist der Antriebsmotor 34 als bekannter Gleichstrommotor ausgebildet, der auf einfache Weise steuerbar ist. Dem Motor 34 bzw. der Antriebsschraube 4 ist ein Lageerkennungsmittel, z.B. ein Encoder oder ein aehnliches Geraet (nicht dargestellt), zugeordnet, wodurch es unter Verwendung bekannter Mittel, die auf dem Markt erhaeltlich sind, moeglich wird, mit Genauigkeit die jeweilige Lage der Fuehrungsrolle 9 gegenueber dem Rahmengestell 4 festzustellen.Advantageously, the drive motor 34 is designed as a known DC motor that can be controlled in a simple manner. A position detection means, e.g. an encoder or a similar device (not shown), which makes it possible, using known means that are available on the market, to determine with precision the respective position of the guide roller 9 relative to the frame 4.

In Fig. 2 befinden sich die Fuehrungsrolle 9 und die mit Strichpunktlinien dargestellte Papierbahn in unterschiedlicher Hoehenanordnung, was unterschiedlichen Registereinstellungen in Laengsrichtung gleichzusetzen ist.In Fig. 2 are the guide roller 9 and the paper web shown with dashed lines in different heights, which is equivalent to different register settings in the longitudinal direction.

Der Fig. 3 kann in Draufsicht eine Seite des Rahmengestells 4 entnommen werden. Besonders kann man in dieser Zeichnung erkennen, dass die Lagerung 3, die mit der darunterliegenden Wand eines Druckelements verbunden ist, mit einem Lager 35 verbunden ist, das drehbar eine Gewindespindel 22 aufnimmt, die mit ihrem anderen Ende mit einem Reduktionsgetriebe 36 verbunden ist, das von einem Motor 23 angetrieben wird. Der Antriebsmotor 23 ist in vorteilhafter Weise als Gleichstrommotor ausgebildet und kann somit in einfacher Weise gesteuert werden. Ferner kann dem Motor 23 oder der Schraube 22 ein Lageanzeigemittel, z.B. ein nicht dargestellter Encoder, zugeordnet sein, womit praezise die oertliche Lage eines Antriebsschlittens, der mit der Schraube 22 in Wirkverbindung steht, angezeigt werden kann. Mit dem Schlitten 21 ist ein Hebelgetriebe 20 wirkverbunden, das gelenkig mit dem Rahmengestell 4, im dargestellten Beispiel mit dem Arm 7', der von der Strebe 7 absteht, verbunden ist.3, one side of the frame 4 can be seen in plan view. In particular, it can be seen in this drawing that the bearing 3, which is connected to the underlying wall of a pressure element, is connected to a bearing 35 which rotatably receives a threaded spindle 22 which is connected at its other end to a reduction gear 36 which is driven by a motor 23. The drive motor 23 is advantageously designed as a DC motor and can thus be controlled in a simple manner. Furthermore, the motor 23 or the screw 22 can be assigned a position indicator, for example an encoder (not shown), with which the local position of a drive carriage, which is in operative connection with the screw 22, can be displayed precisely. A lever mechanism 20 is operatively connected to the slide 21, which is articulatedly connected to the frame 4, in the example shown with the arm 7 ', which projects from the strut 7.

Durch gesteuerte Verschiebung des Schlittens 21 in Richtung des Pfeiles (g) wird es moeglich, den Rahmen 4 in der Horizontalebene (Zeichnungsebene) zu verschwenken. Durch diese Schwenkbewegung, die durch die bogenfoermig verlaufenden Abrollbahnen 30 der Lager 16 und 25 sowie 18 und 26 moeglich wird, eroeffnet sich die Moeglichkeit, die Lage der Achsen Y-Y1 bzw. der Fuehrungsrollen 9 und 10 gegenueber den Lagerungen 2 und 3, die den Rahmen 4 aufnehmen, zu aendern.Controlled displacement of the carriage 21 in the direction of the arrow (g) makes it possible to pivot the frame 4 in the horizontal plane (plane of the drawing). This pivoting movement, which is made possible by the curved rolling tracks 30 of the bearings 16 and 25 and 18 and 26, opens up the possibility of the position of the axes Y-Y1 or of the guide rollers 9 and 10 relative to the bearings 2 and 3, the record the frame 4 to change.

Somit, wie in der Zeichnung mit Strichpunktlinien dargestellt, erfolgt ein Aendern der Laufrichtung der zu bedruckenden Bahn in der horizontalen Ebene, was bedeutet, dass eine Registereinstellung der Bahn 11 in Querrichtung, wie durch den Pfeil (h) in Fig. 3 dargestellt ist, moeglich wird.Thus, as shown in the drawing with dash-dotted lines, there is a change in the running direction of the web to be printed in the horizontal plane, which means that a register setting of the web 11 in the transverse direction, as shown by the arrow (h) in FIG. 3, becomes possible.

Die Funktionsweise der erfindungsgemaessen Vorrichtung 1 ist folgende:
Ist es erwuenscht, die Registereinstellung in Laengsrichtung zu aendern, so genuegt es, von Hand oder automatisch den Motor 34 zu betaetigen, z.B. ueber einen Betaetigungstaster oder eine Steuereinheit, Geraete die mit dem Motor wirkverbunden sind.The mode of operation of the device 1 according to the invention is the following:
If it is desired to change the register setting in the longitudinal direction, it is sufficient to actuate the motor 34 manually or automatically, for example via an actuation button or a control unit, devices which are operatively connected to the motor.

Dies fuehrt dazu, dass die vordere Fuehrungsrolle 9 nach oben oder nach unten verfahren wird, wie dies mit dem Pfeil (i) in Fig. 2 angedeutet ist. Dank der Vorsehung eines Reduziergetriebes 32 erfolgt das Verfahren in Richtung des Pfeiles (i) mit kleinster Teilung, was die Moeglichkeit schafft, eine Einstellung des Registers in Laengsrichtung der Papierbahn 11 mit hoechster Praezision vorzunehmen. Wird hingegen der Motor 23, der dem Schlitten 21 des Rahmens 4 zugeordnet ist, betaetigt, so kann eine Registereinstellung in Querrichtung der Papierbahn 11 erfolgen (Pfeil h in Fig. 3).This leads to the fact that the front guide roller 9 is moved up or down, as indicated by the arrow (i) in FIG. 2. Thanks to the provision of a reduction gear 32, the method is carried out in the direction of arrow (i) with the smallest pitch, which makes it possible to adjust the register in the longitudinal direction of the paper web 11 with the highest precision. If, on the other hand, the motor 23, which is assigned to the carriage 21 of the frame 4, is actuated, a register setting can be made in the transverse direction of the paper web 11 (arrow h in FIG. 3).

Auch diese Registereinstellung, dank der Vorsehung eines Reduziergetriebes 36, ermoeglicht eine Einstellung des Querregisters mit groesster Praezision. Auch der Motor 23 kann von Hand betaetigt werden oder ueber Steuersignale, die z.B. von einer Steuereinheit abgegeben werden, kann die Betaetigung des Motors auch automatisch erfolgen.This register setting, too, thanks to the provision of a reduction gear 36, enables the cross register to be set with the greatest precision. The motor 23 can also be operated manually or via control signals, e.g. are issued by a control unit, the engine can also be operated automatically.

Die erfindungsgemaesse Einrichtung 1 zur Einstellung des Registers hat den Vorteil, dass sie aus einer extrem kompakten und baukastenartigen Struktur besteht, was die Anordnung der Vorrichtung 1 an der Oberseite des Gestells eines jeden Druckelements erlaubt. Ferner zeichnet sich die erfindungsgemaesse Vorrichtung 1 durch erhoehte Funktionstuechtigkeit dank der Verwendung von funktionssicheren Bauelementen aus.The device 1 according to the invention for setting the register has the advantage that it consists of an extreme compact and modular structure, which allows the arrangement of the device 1 on the top of the frame of each pressure element. Furthermore, the device 1 according to the invention is characterized by increased functionality thanks to the use of functionally reliable components.

Bei Auftreten eines Schadens besteht die Moeglichkeit, die Reparaturarbeiten bequem an der Aussenseite des jeweiligen Druckelements durchzufuehren, ohne die Notwendigkeit, im Inneren des Gestells des Druckelements Zylinder oder Rollengruppen, die fuer andere Funktionen vorgesehen sind, ausbauen zu muessen. Sollte sich erweisen, dass die Reparaturen nicht kurzfristig durchfuehrbar sind, so besteht die Moeglichkeit, die Vorrichtung 1 gesamthaft abzubauen und durch eine neue Vorrichtung 1 fuer die Registereinstellung zu ersetzen. Somit werden die Stillstandszeiten der Druckmaschine auf ein Minimum reduziert.If damage occurs, it is possible to carry out the repair work comfortably on the outside of the respective pressure element without the need to remove cylinders or roller groups which are provided for other functions in the interior of the frame of the pressure element. If it turns out that the repairs cannot be carried out at short notice, it is possible to dismantle device 1 as a whole and to replace it with a new device 1 for register adjustment. This reduces the downtimes of the printing press to a minimum.
