Definitions
- the invention relates to a printing unit with impression roller according to the preamble of patent claim 1 and 5, respectively.
- Such printing units are already known and are used for example for gravure printing.
- a forme cylinder is rotatably mounted in the side frames of a printing unit frame.
- a impression roller over which the printing material is guided, adjustable and also turned off again.
- the impression roller is usually mounted at both ends in Presseurplatten that can be moved relative to the side frames along a first path.
- guide rolls are generally present in such a printing unit, over which the printing material is guided and the frame-fixed or are mounted on the Presseurplatten.
- the lower edge of the protective grid must not be spaced more than 5 mm from the surface of the forme cylinder.
- the distance to the surface of the impression roller must not exceed a certain value during printing operation.
- the protective grid must maintain a minimum distance in order to thread the substrate manually between the impression roller and the protective grid.
- the DE 42 04 142 A1 shows such a printing unit that meets the accident prevention regulations.
- a printing unit is shown in which the impression roller in a position at a great distance to the forme cylinder - the so-called neutral position - is movable.
- the protective grid is moved with the impression roller or the impression plate, so that the access to the form cylinder is free, so that it can be replaced by a forme cylinder larger or smaller diameter - depending on the desired printing length of the forme cylinder.
- the cited document also shows guides in which the protective grid is guided along a second path, so that the distance between the protective grid and the forme cylinder when the impression roller is turned on is automatically no more than 5 mm for each diameter of the forme cylinder.
- the protective grid is moved along with the movement of the impression roller.
- the impression roller which has a soft pressurm coat
- the protective grid prevents free access to the impression roller.
- the protective grid makes it difficult to remove the printing material from the impression roller. However, this is necessary in order to change the impression roller or at least the Presseurmantel.
- the object of the invention is therefore to propose a generic printing unit and a generic method for positioning a protective grille, in which the protective grille makes it difficult neither free access to the impression roller when changing nor the removal of the printing material from the impression roller.
- the problem is solved by the characterizing features of claims 1 and 5.
- the second travel of the protective grid is smaller than the travel of the impression.
- the printing press can continue to print with all other printing units, while at the non-printing printing unit the Presseurmantel can be changed.
- the protective grid and the impression roller on a mechanical connection containing resilient elements. In this way, it is easily possible to move the protective grid with the impression roller, while providing another, such as a shorter, travel path.
- the second travel path of the protective grid is limited by a stop.
- This stop is advantageously fixed to the frame, so that it can be ruled out under all circumstances that the protective grid comes into contact with the printing material.
- the invention further comprises a method for positioning a protective grid for covering an inlet gap between the forme cylinder and the impression roller, in which the protective grate is moved along a second travel path when the impression roller is switched on or off by the forme cylinder and thereby moved along a first travel path.
- the protective grid is moved a smaller distance than the impression roller.
- This positioning can be carried out particularly advantageously if the process of the protective grid takes place at the same speed as the movement of the impression roller, at least for a certain period of time. This is possible in a simple manner in that the protective grid is kept at rest relative to the Presseurplatten during this period.
- the protective grid is held firmly towards the end of the movement relative to the machine frame.
- Fig. 1 shows an inventive printing unit 1, from the printing unit frame, the front side frame for reasons of clarity is not shown, so that the rear side frame 2 is visible.
- the guide rollers 3, 4, 5 are rotatably mounted in the printing unit frame.
- the substrate 6 is guided in the transport direction x through the printing unit 1.
- the printing substrate 6 is additionally guided over the impression roller 7.
- the impression roller 7 is employed against the forme cylinder 8.
- This form cylinder 8 rotates in the direction of rotation R and removes ink from a paint reservoir and transfers them to the substrate 6.
- the impression roller 7 is displaceable relative to the printing unit frame.
- the impression roller 7 is rotatably mounted in impression roller plates 9, of which only the rear one is visible in FIG. 1.
- invisible guides are mounted, which run on mounted on the side frames 2 tooth rails 10, so that a linear movability of the Presseurplatten is ensured.
- the procedure itself takes place by means of the method, which can be configured as a lifting drive 12.
- the lifting drive 12 acts on a pull rod 11.
- the lifting drive 12 facing away from the end of the pull rod 11 is connected to the Presseurplatte 9.
- the lifting drive 12 may be, for example, a known per se spindle drive or a piston-cylinder unit. Other forms of linear actuators can be used at this point.
- the inlet gap between the impression roller 7 and the forme cylinder 8 is covered by a protective grid 13.
- the lower edge of the protective grid 13 to the peripheral surface of the forme cylinder 8 has a small distance of a maximum of 5 mm.
- the protective grid 13 is attached at both ends to curved pieces 14. These curved pieces 14 are guided by rollers which are mounted between the fasteners 15 and the lever arm 16.
- the lever arm 16 is rotatably mounted in a side plate 17. In this fulcrum, a link 18 is additionally rotatably mounted.
- a connecting rod 19 is pivotally mounted, which transmits the rotational movement of the handlebar 18 on the curved piece 14, so that ultimately the protective grid 13 can perform a rotation on a circular path concentrically around the impression roller 7 by a rotation of the arm 18 ,
- the handlebar 18 in turn is set by a mounted on the side frame 2 guide 20 in a rotary motion.
- the handlebar 18 carries at its end facing away from the connecting rod 19 a roller or a sliding block, which runs along the guide 20 during a lifting movement of the side plate 17.
- the guide 20 is shaped so that when lifting the side plate 17, which is raised over a certain stroke distance together with the Presseurplatte 9, and the guard 13 is moved along a right turn.
- the protective grille moves accordingly on a left turn.
- the distance between the lower edge of the protective grid 13 and the forme cylinder is kept smaller than 5 mm in this way, even with different sized cylinders 8, the different heights of the impression roller 7 and thus the protective grid 13 necessary.
- the arm 16 has on its side facing away from the protective grid on a guide groove 21 in which a roller 22 attached to the Presseurplatte 9 runs. If now the Presseurplatte 9 is displaced relative to the side plate 17, the roller 22 along the guide groove 21 along, which is formed such that then the lower end of the lever arm 16 and thus the protective grid 13 is pivoted away from the impression roller 7.
- the guide groove 21 may be attached to the side frame 2.
- the lever arm 16 in this case carries the roller 22, which then runs in the guide groove 21 and moves the lever arm 16 in accordance with the course of the guide groove 21. In this embodiment, the lever arm 16 is pivoted immediately with the lifting of the Presseurplatte 9 of the impression roller 7.
- the impression roller plate 9 is raised, first the side plate 17, which, as can be seen from FIG. 2, is suspended by means of springs 23 on the impression roller plate 9, is first lifted with it.
- the role of the handlebar 18 runs, as already described, along the guide 20. After a certain stroke, the side plate 17 abuts against a fixed to the side frame 2 and not visible in FIG. 2 stop 24.
- the impression plate 9 can be moved further upwards, while the side plate 17 remains in its assumed position. In this way, the impression roller 7 can be lifted from the printing material 6, while the protective grid 13 remains below the printing substrate 6. This situation is shown in FIG.
- the printing material 6 can thus be printed and processed by other printing units or other processing machines while the illustrated printing unit 1 is being maintained or prepared for another print job.
- FIG. 3 shows a detail of the side view of the printing unit 1, which is located in the position shown in Fig. 2. From this figure is the Way visible to which the Presseurplatte 9 and the side plate 17 are interconnected. At the lower edge of the side plate 17, a plate 25 is fixed substantially at right angles. On the plate turn two hooks 26, only one of which is visible, screwed. In the hooks 26 springs 23 are mounted. The other ends of the springs 23 are fixed to bolts 27 which are fixed to the Presseurplatten 9. The length of the springs 23 is determined so that they are still slightly under tension even when pulled together, so for example when the printing unit is in printing position.
- the impression roller plate 9 is first lifted by means of the lifting drive 12. About the springs 23, the side plate 17 is also raised. After a certain stroke, the plate 25 abuts against the frame-fixed stop 24, so that the side plate 17 can not move further up. The position of the stop 24 is set at a height, so that the protective grid 13 remains below the printing material 6. However, the impression roller plate 9 can be raised further until the impression roller 7 has a sufficient distance for maintenance to the printing material 6.

Abstract
Description
Die Erfindung betrifft ein Druckwerk mit Presseur gemäß dem Oberbegriff des Patentanspruchs 1 bzw. 5.The invention relates to a printing unit with impression roller according to the preamble of
Derartige Druckwerke sind bereits bekannt und werden beispielsweise für den Tiefdruck eingesetzt. Bei solchen Druckwerken, von denen mehrere in einer Druckmaschine vorhanden sein können, ist ein Formzylinder drehbar in den Seitengestellen eines Druckwerkrahmens gelagert. Gegen diesen Formzylinder ist ein Presseur, über den der Bedruckstoff geführt wird, anstellbar und auch wieder abstellbar. Hierzu ist der Presseur gewöhnlich beidendig in Presseurplatten gelagert, die relativ zu den Seitengestellen entlang eines ersten Verfahrweges verfahren werden können. Weiterhin sind in einem derartigen Druckwerk in der Regel Leitwalzen vorhanden, über welche der Bedruckstoff geführt wird und die gestellfest oder an den Presseurplatten gelagert sind.Such printing units are already known and are used for example for gravure printing. In such printing units, several of which may be present in a printing press, a forme cylinder is rotatably mounted in the side frames of a printing unit frame. Against this forme cylinder is a impression roller over which the printing material is guided, adjustable and also turned off again. For this purpose, the impression roller is usually mounted at both ends in Presseurplatten that can be moved relative to the side frames along a first path. Furthermore, guide rolls are generally present in such a printing unit, over which the printing material is guided and the frame-fixed or are mounted on the Presseurplatten.
Unfallverhütungsvorschriften schreiben vor, dass an einem solchen Druckwerk der Einlaufspalt zwischen Presseur und Formzylinder mit einem Schutzgitter so abgedeckt sein muss, dass beispielsweise das Bedienpersonal nicht unbeabsichtigt in den Einlaufspalt fassen kann. Dazu darf die untere Kante des Schutzgitters nicht weiter als 5 mm zur Oberfläche des Formzylinders beabstandet sein. Der Abstand zur Oberfläche des Presseurs darf ebenfalls im Druckbetrieb einen bestimmten Wert nicht überschreiten. Andererseits muss das Schutzgitter einen Mindestabstand einhalten, um den Bedruckstoff händisch zwischen Presseur und Schutzgitter einfädeln zu können.Accident prevention regulations stipulate that at such a printing unit, the inlet gap between impression roller and form cylinder with a protective grid must be covered so that, for example, the operator can not inadvertently grasp in the inlet gap. For this purpose, the lower edge of the protective grid must not be spaced more than 5 mm from the surface of the forme cylinder. The distance to the surface of the impression roller must not exceed a certain value during printing operation. On the other hand, the protective grid must maintain a minimum distance in order to thread the substrate manually between the impression roller and the protective grid.
Die
Bei einer gattungsgemäßen Druckmaschine unterliegt der Presseur, der einen weichen Presseurmantel aufweist, einem ständigen Verschleiß, so dass dieser oder zumindest der Presseurmantel nach gewissen Standzeiten ausgewechselt werden muss. Dabei verhindert allerdings das Schutzgitter einen freien Zugriff auf den Presseur. Zudem erschwert das Schutzgitter das Entfernen des Bedruckstoffes vom Presseur. Dies ist allerdings notwendig, um den Presseur oder zumindest den Presseurmantel wechseln zu können.In a generic printing machine, the impression roller, which has a soft pressurm coat, is subject to constant wear, so that this or at least the pressurm coat must be replaced after a certain service life. However, the protective grid prevents free access to the impression roller. In addition, the protective grid makes it difficult to remove the printing material from the impression roller. However, this is necessary in order to change the impression roller or at least the Presseurmantel.
Die Aufgabe der Erfindung ist es daher, ein gattungsgemäßes Druckwerk und ein gattungsgemäßes Verfahren zum Positionieren eines Schutzgitters vorzuschlagen, bei_ dem das Schutzgitter weder den freien Zugriff auf den Presseur beim Wechseln noch das Entfernen des Bedruckstoffes vom Presseur erschwert.
Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale der Ansprüche 1 und 5.The object of the invention is therefore to propose a generic printing unit and a generic method for positioning a protective grille, in which the protective grille makes it difficult neither free access to the impression roller when changing nor the removal of the printing material from the impression roller.
The problem is solved by the characterizing features of
Demnach ist der zweite Verfahrweg des Schutzgitters kleiner als der Verfahrweg des Presseurs. Damit ist es möglich, dass der Presseur weiter von dem Formzylinder entfernt wird als das Schutzgitter. Dabei ist es sogar möglich, dass der Presseur soweit angehoben wird, dass er nicht mehr mit dem Bedruckstoff in Kontakt steht, während das Schutzgitter nur soweit angehoben wird, dass es noch nicht den Bedruckstoff, welcher nunmehr nur noch über die Leitwalzen des Druckwerkes geführt wird, berührt. In diesem Fall kann die Druckmaschine mit allen anderen Druckwerken weiter drucken, während an dem nicht druckenden Druckwerk der Presseurmantel gewechselt werden kann.Accordingly, the second travel of the protective grid is smaller than the travel of the impression. This makes it possible for the impression roller to be further removed from the forme cylinder than the protective grille. It is even possible that the impression roller is raised so far that he no longer with the Substrate is in contact while the protective grid is raised only so far that it does not touch the substrate, which is now only performed on the guide rollers of the printing unit. In this case, the printing press can continue to print with all other printing units, while at the non-printing printing unit the Presseurmantel can be changed.
In bevorzugter Ausgestaltung der Erfindung weisen das Schutzgitter und der Presseur eine mechanische Verbindung auf, die federnde Elemente enthält. Auf diese Weise ist es einfach möglich, das Schutzgitter mit dem Presseur zu verfahren, dabei aber einen anderen, etwa einen kürzeren, Verfahrweg vorzusehen.In a preferred embodiment of the invention, the protective grid and the impression roller on a mechanical connection containing resilient elements. In this way, it is easily possible to move the protective grid with the impression roller, while providing another, such as a shorter, travel path.
Von besonderem Vorteil ist es, wenn der zweite Verfahrweg des Schutzgitters durch einen Anschlag begrenzt ist. Dieser Anschlag ist vorteilhafterweise gestellfest, so dass unter allen Umständen ausgeschlossen werden kann, dass das Schutzgitter mit dem Bedruckstoff in Kontakt kommt.It is particularly advantageous if the second travel path of the protective grid is limited by a stop. This stop is advantageously fixed to the frame, so that it can be ruled out under all circumstances that the protective grid comes into contact with the printing material.
Die Erfindung umfasst weiterhin ein Verfahren zum Positionieren eines Schutzgitters zur Abdeckung eines Einlaufspalts zwischen Formzylinder und Presseur, bei welchem das Schutzgitter entlang eines zweiten Verfahrweges verfahren wird, wenn der Presseur von dem Formzylinder an- oder abgestellt und dabei entlang eines ersten Verfahrweges verfahren wird. Dabei wird das Schutzgitter um eine kleinere Strecke als der Presseur verfahren.The invention further comprises a method for positioning a protective grid for covering an inlet gap between the forme cylinder and the impression roller, in which the protective grate is moved along a second travel path when the impression roller is switched on or off by the forme cylinder and thereby moved along a first travel path. The protective grid is moved a smaller distance than the impression roller.
Besonders vorteilhaft lässt sich dieses Positionieren ausführen, wenn das Verfahren des Schutzgitters zumindest während einer bestimmten Zeitspanne mit gleicher Geschwindigkeit wie das Verfahren des Presseurs erfolgt. Dieses ist auf einfache Weise dadurch möglich, dass das Schutzgitter während dieser Zeitspanne relativ zu den Presseurplatten in Ruhe gehalten wird.This positioning can be carried out particularly advantageously if the process of the protective grid takes place at the same speed as the movement of the impression roller, at least for a certain period of time. This is possible in a simple manner in that the protective grid is kept at rest relative to the Presseurplatten during this period.
In weiterer Ausgestaltung des Verfahrens ist" vorgesehen, dass nach dieser Zeitspanne, in welcher das Schutzgitter mit gleicher Geschwindigkeit wie das Verfahren des Presseurs erfolgt, die Geschwindigkeit im weiteren Verlauf der Verfahrbewegung des Presseurs gesenkt wird. Auf diese Weise wird der Verfahrweg des Schutzgitters kleiner als der des Presseurs gehalten. In bevorzugter Ausgestaltung wird das Schutzgitter gegen Ende der Verfahrbewegung relativ zum Maschinengestell fest gehalten.In a further embodiment of the method, it is provided that, after this period of time in which the protective grid takes place at the same speed as the method of the impression roller, the speed is reduced in the further course of the movement of the impression roller Travel of the protective grid is kept smaller than that of the impression roller. In a preferred embodiment, the protective grid is held firmly towards the end of the movement relative to the machine frame.

Fig. 1 zeigt ein erfindungsgemäßes Druckwerk 1, von dessen Druckwerksrahmen das vordere Seitengestell aus Gründen der besseren Übersichtlichkeit nicht dargestellt ist, so dass das hintere Seitengestell 2 sichtbar ist. Über ebenfalls nicht dargestellte Anbauten an die Seitengestelle 2 sind die Leitwalzen 3, 4, 5 drehbar im Druckwerksrahmen gelagert. Über diese Leitwalzen 3, 4, 5 wird der Bedruckstoff 6 in Transportrichtung x durch das Druckwerk 1 geführt. Im in Fig. 1 dargestellten Druckbetrieb wird der Bedruckstoff 6 zusätzlich über den Presseur 7 geführt. Der Presseur 7 ist dabei gegen den Formzylinder 8 angestellt. Dieser Formzylinder 8 rotiert in der Rotationsrichtung R und entnimmt Druckfarbe aus einem Farbreservoir und überträgt diese auf den Bedruckstoff 6. Um den Presseur 7 vom Formzylinder 8 und auch vom Bedruckstoff 6 abheben zu können, aber auch um die Position des Presseurs 7 auf die verschiedenen Umfänge des Formzylinders 8 anpassen zu können, ist der Presseur 7 relativ zum Druckwerksrahmen verschiebbar. Zu diesem Zweck ist der Presseur 7 in Presseurplatten 9, von denen in der Fig. 1 nur die hintere sichtbar ist, drehbar gelagert. An den Presseurplatten 9 sind nicht sichtbare Führungen angebracht, die auf an den Seitengestellen 2 angebrachten Zahnschienen 10 laufen, so dass eine lineare Verfahrbarkeit der Presseurplatten sichergestellt ist. Das Verfahren selbst erfolgt durch Mittel zum Verfahren, welche als Hubantrieb 12 ausgestaltet sein können. Der Hubantrieb 12 wirkt auf eine Zugstange 11. Das dem Hubantrieb 12 abgewandte Ende der Zugstange 11 ist mit der Presseurplatte 9 verbunden. Der Hubantrieb 12 kann beispielweise ein an sich bekannter Spindelantrieb oder auch eine Kolbenzylindereinheit sein. Auch weitere Formen von Hubantrieben sind an dieser Stelle einsetzbar.Fig. 1 shows an
Der Einlaufspalt zwischen dem Presseur 7 und dem Formzylinder 8 ist durch ein Schutzgitter 13 abgedeckt. Im dargestellten Druckbetrieb hat die Unterkante des Schutzgitters 13 zur Umfangsfläche des Formzylinders 8 einen geringen Abstand von maximal 5 mm. Das Schutzgitter 13 ist beidendig an Kurvenstücken 14 befestigt. Diese Kurvenstücke 14 werden von Rollen geführt, die zwischen den Befestigungen 15 und dem Hebelarm 16 angebracht sind. Der Hebelarm 16 ist in einer Seitenplatte 17 drehbar gelagert. In diesem Drehpunkt ist zusätzlich ein Lenker 18 drehbar gelagert. An einem Ende des Lenkers 18 ist eine Verbindungsstange 19 gelenkig angebracht, die die Drehbewegung des Lenkers 18 auf das Kurvenstück 14 überträgt, so dass letztendlich das Schutzgitter 13 durch eine Drehung des Lenkers 18 eine Bewegung auf einer Kreisbahn konzentrisch um den Presseur 7 herum vollführen kann. Der Lenker 18 wiederum wird durch eine am Seitengestell 2 befestigte Führung 20 in eine Drehbewegung versetzt. Dazu trägt der Lenker 18 an seinem der Verbindungsstange 19 abgewandten Ende eine Rolle oder einen Gleitstein, die oder der bei einer Hubbewegung der Seitenplatte 17 entlang der Führung 20 verläuft. Die Führung 20 ist dabei so geformt, dass bei einem Anheben der Seitenplatte 17, die über eine bestimmte Hubstrecke gemeinsam mit der Presseurplatte 9 anhebbar ist, auch das Schutzgitter 13 entlang einer Rechtskurve bewegt wird. In einer Ausführung der Erfindung, bei der der Formzylinder 8 links herum rotiert, bewegt sich das Schutzgitter entsprechend auf einer Linkskurve. Insgesamt wird auf diese Weise auch bei verschieden großen Formzylindern 8, die verschiedene Höhenlagen des Presseurs 7 und damit des Schutzgitters 13 notwendig machen, der Abstand zwischen der Unterkante des Schutzgitters 13 und dem Formzylinder kleiner als 5 mm gehalten.The inlet gap between the
Der Arm 16 weist an seiner dem Schutzgitter abgewandten Seite eine Führungsnut 21 auf, in der eine an der Presseurplatte 9 befestigte Rolle 22 läuft. Wird nun die Presseurplatte 9 relativ zur Seitenplatte 17 verschoben, so läuft die Rolle 22 die Führungsnut 21 entlang, die derart ausgeformt ist, dass dann das untere Ende des Hebelarms 16 und damit das Schutzgitter 13 vom Presseur 7 abgeschwenkt wird. In einer anderen Ausführungsform der Erfindung kann aber auch die Führungsnut 21 am Seitengestell 2 befestigt sein. Der Hebelarm 16 trägt in diesem Fall die Rolle 22, welche dann in der Führungsnut 21 läuft und den Hebelarm 16 entsprechend des Verlaufs der Führungsnut 21 bewegt. In dieser Ausführungsform wird der Hebelarm 16 unmittelbar mit dem Anheben der Presseurplatte 9 von dem Presseur 7 abgeschwenkt.The
Wird nun die Presseurplatte 9 angehoben, so wird zunächst die Seitenplatte 17, die, wie aus der Fig. 2 ersichtlich, über Federn 23 an der Presseurplatte 9 aufgehängt ist, zunächst mit angehoben. Die Rolle des Lenkers 18 läuft, wie bereits beschrieben, entlang der Führung 20. Nach einer gewissen Hubstrecke stößt die Seitenplatte 17 gegen einen am Seitengestell 2 befestigten und in der Fig. 2 nicht sichtbaren Anschlag 24. Die Presseurplatte 9 kann weiter aufwärts bewegt werden, während die Seitenplatte 17 in ihrer eingenommenen Position verbleibt. Auf diese Weise kann der Presseur 7 vom Bedruckstoff 6 abgehoben werden, während das Schutzgitter 13 unterhalb des Bedruckstoffes 6 verbleibt. Diese Situation ist in Fig. 2 dargestellt. Hat der Presseur 7 seine dargestellte, obere Neutralposition erreicht, in der er einen größeren Abstand zum Bedruckstoff 6 eingenommen hat, können Wartungsarbeiten, beispielsweise das Wechseln des Presseurmantels, durchgeführt werden, während der Bedruckstoff weiterhin über die Leitwalzen 3, 4, 5 ungehindert durch das Druckwerk geführt werden kann. Der Bedruckstoff 6 kann also, während das gezeigte Druckwerk 1 gewartet oder für einen anderen Druckauftrag gerüstet wird, von anderen Druckwerken oder anderen Verarbeitungsmaschinen bedruckt und verarbeitet werden.If now the
Die Fig. 3 zeigt einen Ausschnitt der Seitenansicht auf das Druckwerk 1, das sich in der in Fig. 2 dargestellten Position befindet. Aus dieser Figur ist die Weise ersichtlich, auf die die Presseurplatte 9 und die Seitenplatte 17 miteinander verbunden sind. An der Unterkante der Seitenplatte 17 ist im wesentlichen rechtwinklig ein Platte 25 befestigt. An der Platte wiederum sind zwei Haken 26, von denen nur einer sichtbar ist, eingeschraubt. In die Haken 26 sind Federn 23 eingehängt. Die anderen Enden der Federn 23 sind an Bolzen 27 befestigt, welche an den Presseurplatten 9 befestigt sind. Die Länge der Federn 23 ist so bestimmt, dass sie auch in zusammen gezogenem Zustand, also beispielsweise wenn das Druckwerk in Druckposition ist, noch leicht unter Zugspannung stehen.3 shows a detail of the side view of the
Zum Erreichen der dargestellten Position wird zunächst die Presseurplatte 9 mithilfe des Hubantriebes 12 angehoben. Über die Federn 23 wird ebenso die Seitenplatte 17 angehoben. Nach einer gewissen Hubstrecke stößt die Platte 25 gegen den gestellfesten Anschlag 24, so dass sich die Seitenplatte 17 nicht weiter aufwärts bewegen lässt. Die Position des Anschlags 24 ist auf eine Höhe festgelegt, so dass das Schutzgitter 13 unterhalb des Bedruckstoffes 6 verbleibt. Die Presseurplatte 9 kann jedoch weiter angehoben werden, bis der Presseur 7 einen für Wartungsarbeiten ausreichenden Abstand zum Bedruckstoff 6 hat.
