Die in Fig. 1 gezeigte Vorrichtung enthält einen Träger 1, der als Profil ausgebildet ist, das heißt einen profilförmigen Querschnitt besitzt, wie in Fig. 2 gezeigt. Der Träger 1 beinhaltet in seiner Längsrichtung nebeneinander angeordnet zwölf Arbeitszylinder 2 bis 13, die in jeweils eine Bohrung 14 eingesteckt und befestigt sind. Statt der pneumatischen Arbeitszylinder 2 bis 13 könnten auch hydraulische Arbeitszylinder zur Anwendung kommen. Die Arbeitszylinder 2 bis 13 weisen vorteilhaft einen topfförmigen Zylinder 15 auf, in dem sich ein Kolben 16 nebst Kolbenstange 17 befindet. An jeder Kolbenstange 17 ist eine Achse 18 befestigt, auf der zwei Andrückrollen 19 drehbar gelagert sind (Fig. 1, 6). Stattdessen könnte beispielsweise an einer Kolbenstange 17 auch nur eine Andrückrolle 19 in einer Gabel gelagert sein.In the Fig. 1 The apparatus shown comprises a carrier 1, which is formed as a profile, that is, has a profile-shaped cross-section, as in Fig. 2 shown. The carrier 1 includes in its longitudinal direction juxtaposed twelve working cylinder 2 to 13, which are inserted and secured in a respective bore 14. Instead of the pneumatic cylinder 2 to 13 and hydraulic cylinder could be used. The working cylinders 2 to 13 advantageously have a cup-shaped cylinder 15, in which a piston 16 together with the piston rod 17 is located. On each piston rod 17, an axle 18 is fixed, on which two pressure rollers 19 are rotatably mounted ( Fig. 1 . 6 ). Instead, for example, on a piston rod 17, only one pressure roller 19 could be mounted in a fork.

Die Vorrichtung ist längs eines Formzylinders 20 angeordnet, der in Achsrichtung nebeneinander vier Druckformen 21 bis 24 trägt. In Fig. 6 sind schematisch diese Druckformen 21 bis 24 dargestellt. Statt an einem Formzylinder könnte die Vorrichtung beispielsweise auch an einem Übertragungszylinder angeordnet sein, der als Bespannung ein Gummituch trägt. Der Träger 1 weist in Längsrichtung einen ersten Kanal 25 auf, der mit den Druckräumen 29 für das Einfahren der Andrückrollen 19, also mit den kolbenstangenseitigen Druckräumen, aller Arbeitszylinder 2 bis 13 in Strömungsverbindung steht. Hierzu weist der Zylinder 15 eine Bohrung 26 auf, die über ein Kanalsystem 27 mit dem ersten Kanal 25 in Verbindung steht (Fig. 2). Es stehen weiterhin von den einer Druckform 21 bis 24 zugeordneten Arbeitszylindern 2 bis 13 die Druckräume 28 für das Ausfahren der Andrückrollen 19, also die kolbenbodenseitigen Druckräume, jeweils mit einem separaten Kanal 30 bis 33 in Strömungsverbindung. Im einzelnen stehen die kolbenbodenseitigen Druckräume der Arbeitszylinder 2 bis 4 mit dem Kanal 30, die kolbenbodenseitigen Druckräume der Arbeitszylinder 5 bis 7 mit dem Kanal 32, die kolbenbodenseitigen Druckräume der Arbeitszylinder 8 bis 10 mit dem Kanal 32 und die kolbenbodenseitigen Druckräume der Arbeitszylinder 11 bis 13 mit dem Kanal 33 in Strömungsverbindung. Zur Herstellung dieser Verbindung ist der Boden des Zylinders 15 mit einem Loch 34 versehen. Außerdem steht die Bohrung 14 über eine Querbohrung 34 mit dem zugehörigen Kanal 30 bzw. 31 bzw. 32 bzw. 33 in Verbindung. Die Bohrung 14 ist zum Boden des Zylinders 15 mit einem Rundring 36 abgedichtet. An den längsseitigen Enden des Trägers 1 ist jeweils eine Endplatte 37 angeschraubt, die Gewindebohrungen 38 aufweist, in die die Kanäle 25, 30 bis 33 des Trägers 1 münden. Während in die eine Endplatte 37 Anschlussstücke 39 für den Anschluss der die Druckluft zuführenden Schläuche in die Gewindebohrungen 38 eingeschraubt sind (Fig. 1), sind die Gewindebohrungen 38 der anderen Endplatte 37 mit Verschlussschrauben 40 verschlossen. Letzteres wurde in Fig. 5 anstelle der darzustellenden Anschlussstücke 39 gezeigt. Dank dem immer gleichartigen Abschluss des Trägers 1 mit den Endplatten 37 sind einfach Vorrichtungen für verschieden lange Druckwerkzylinder realisierbar, da diese sich im Wesentlichen nur im Längenmaß des Trägers 1 und in der Anzahl von Bohrungen 14 zur Aufnahme der Arbeitszylinder 2 bis 13 unterscheiden. Die wahlweise Bestückung der Endplatten 37 mit Anschlussstücken 39 oder Verschlussschrauben 40 gibt die Möglichkeit, auch bei unterschiedlichen Einbaulagen der Vorrichtung, zum Beispiel an rechts- oder linksdrehende Druckwerkzylinder, die Druckluft in die Vorrichtung immer von der gleichen Gestellseite einer Druckeinheit zuzuführen. Der Träger 1 wird vorteilhaft aus einem Leichtmetall-Strangpressprofil hergestellt. Das Profil enthält als geschlossenes Profil bereits die Kanäle 25, 30 bis 33 für die Luftversorgung und kann mit weiteren Aussparungen versehen werden, die eine Optimierung von hoher Steifigkeit und geringer Masse zulassen.The device is arranged along a forme cylinder 20 which carries four printing plates 21 to 24 next to one another in the axial direction. In Fig. 6 These printing plates 21 to 24 are shown schematically. Instead of a forme cylinder, the device could for example also be arranged on a transfer cylinder, which carries a blanket as a covering. The carrier 1 has, in the longitudinal direction, a first channel 25, which communicates with the pressure chambers 29 for retracting the pressure rollers 19, that is to say with the piston rod-side pressure chambers, of all working cylinders 2 to 13. For this purpose, the cylinder 15 has a bore 26 which communicates via a channel system 27 with the first channel 25 ( Fig. 2 ). Furthermore, the pressure chambers 28 for the extension of the pressure rollers 19 are available from the working cylinders 2 to 13 assigned to a printing forme 21 to 24. So the piston bottom side pressure chambers, each with a separate channel 30 to 33 in flow communication. Specifically, the piston bottom side pressure chambers of the working cylinder 2 to 4 with the channel 30, the piston bottom side pressure chambers of the working cylinder 5 to 7 with the channel 32, the piston bottom side pressure chambers of the working cylinder 8 to 10 with the channel 32 and the piston bottom side pressure chambers of the working cylinder 11 to 13th with the channel 33 in fluid communication. To make this connection, the bottom of the cylinder 15 is provided with a hole 34. In addition, the bore 14 is connected via a transverse bore 34 with the associated channel 30 or 31 or 32 or 33 in conjunction. The bore 14 is sealed to the bottom of the cylinder 15 with a circular ring 36. At the longitudinal ends of the carrier 1 in each case an end plate 37 is screwed, which has threaded holes 38 into which the channels 25, 30 to 33 of the carrier 1 open. While in the one end plate 37 connecting pieces 39 for the connection of the compressed air supplying hoses are screwed into the threaded holes 38 ( Fig. 1 ), the threaded holes 38 of the other end plate 37 are closed with screw plugs 40. The latter was in Fig. 5 shown in place of the connecting pieces 39 to be shown. Thanks to the always similar conclusion of the carrier 1 with the end plates 37 devices for different lengths of printing cylinder are easy to implement, as they differ substantially only in the length of the carrier 1 and in the number of holes 14 for receiving the working cylinder 2 to 13. The optional equipping of the end plates 37 with connectors 39 or locking screws 40 makes it possible to supply the compressed air into the device always from the same frame side of a printing unit, even at different mounting positions of the device, for example, to right- or left-rotating printing cylinder. The carrier 1 is advantageously made of a light metal extruded profile. The profile contains as a closed profile already the channels 25, 30 to 33 for the air supply and can be provided with further recesses, which allow an optimization of high stiffness and low mass.

Die Andrückrollen 19 sind in einem Schutzgehäuse 41 angeordnet, das zum Formzylinder 20 hin mit vier nebeneinander angeordneten Öffnungsklappen 42 bis 45 abschließt. Dabei ist jeder Druckform 21 bis 24 jeweils eine Öffnungsklappe 42 bis 45 zugeordnet (Fig. 6). Die Öffnungsklappen 42 bis 45 sind aus einem zwischen den Andrückrollen 19 und dem Formzylinder 20 befindlichen Verstellbereich der Andrückrollen 19 wegbewegbar. Hierzu sind die Öffnungsklappen 42 bis 45 schwenkbar an dem Schutzgehäuse 41 gelagert und tragen ein Drehgelenk 46, an dem eine Koppel 47 angelenkt ist, die schwenkbar mit der Kolbenstange 17 eines Arbeitszylinders 2 bis 13 verbunden ist. Vorteilhaft ist die Koppel 47 drehbar auf der an der Kolbenstange 17 befestigten Achse 18 gelagert (Fig. 6 und 2). Die Kolbenstange 17, die Koppel 47, die Öffnungsklappe 42 bis 45 und das Schutzgehäuse 41 bilden ein Schubkurbelgetriebe. Durch diese Getriebeverbindung der Öffnungsklappen 42 bis 45 mit jeweils einem Arbeitszylinder werden unter Entfall separater Antriebe beim Aus- und Einfahren der Andrückrollen 19 die Öffnungsklappen 42 bis 45 geöffnet bzw. geschlossen. Die Anwendbarkeit des Antriebes der Öffnungsklappen ist nicht auf die beschriebene Ausführung des Trägers der Vorrichtung zum Andrücken einer Bespannung beschränkt.The pressure rollers 19 are arranged in a protective housing 41, which closes the forme cylinder 20 with four side by side opening flaps 42 to 45. Each printing plate 21 to 24 is assigned an opening flap 42 to 45 ( Fig. 6 ). The opening flaps 42 to 45 are from an intermediate the pressure rollers 19 and the forme cylinder 20 located adjustment range of the pressure rollers 19 wegbewegbar. For this purpose, the opening flaps 42 to 45 are pivotally mounted on the protective housing 41 and carry a swivel joint 46, on which a coupling 47 is articulated, which is pivotally connected to the piston rod 17 of a working cylinder 2 to 13. Advantageously, the coupling 47 is rotatably mounted on the attached to the piston rod 17 axis 18 ( Fig. 6 and 2 ). The piston rod 17, the coupling 47, the opening flap 42 to 45 and the protective housing 41 form a slider-crank mechanism. Through this gear connection of the opening flaps 42 to 45, each with a working cylinder, the opening flaps 42 to 45 are opened or closed with the elimination of separate drives when extending and retracting the pressure rollers 19. The applicability of the drive of the opening flaps is not limited to the described embodiment of the support of the device for pressing a fabric.

Das Schutzgehäuse 41 hat einen U-förmigen Querschnitt, wobei ein Schenkel 48 sowie die Öffnungsklappe 42 bis 45 im geöffneten Zustand als Schutz für die Einlaufspalte zwischen den Andrückrollen 19 und dem Formzylinder 20 dienen. Dabei ist auf den einen Schenkel 48 eine zu dem Einlaufspalt verstellbare Leiste 49 geschraubt (Fig. 2 und 3).The protective housing 41 has a U-shaped cross section, wherein a leg 48 and the opening flap 42 to 45 in the open state serve as protection for the inlet gaps between the pressure rollers 19 and the forme cylinder 20. In this case, on the one leg 48, an adjustable to the inlet gap bar 49 is screwed ( Fig. 2 and 3 ).

Die Vorrichtung ist um eine Achse 50 von dem Formzylinder wegschwenkbar. Hierzu ist die Vorrichtung auf zwei in das Gestell eingeschraubten, auf der Achse 50 angeordneten Gewindebolzen 51 gelagert (Fig. 4). Im einzelnen ist an den Enden des Trägers 1 jeweils eine Tragplatte 53 befestigt, die eine Senkbohrung 52 enthält, mit der die Tragplatte 53 auf einem Bund 54 des Gewindebolzens 51 lagert. Jeder Gewindebolzen 51 ist mittelbar in das Gestell der Rotationsdruckmaschine geschraubt, und zwar in eine Buchse 55, die an ein Seitenblech 56 angeschraubt ist, das im Gestell der Rotationsdruckmaschine befestigt ist. Zentrisch zur Senkbohrung 52 weist die Tragplatte 53 noch eine durchgehende Bohrung 57 auf, in die ein zylindrischer Ansatz 58 der Buchse 55 ragt. Von dieser Bohrung 57 führt eine die Senkbohrung 52 mit erfassende Ausschlitzung 59 zum Rand der Tragplatte 53.The device is pivotable about an axis 50 of the forme cylinder. For this purpose, the device is mounted on two threaded into the frame, mounted on the axis 50 threaded bolt 51 ( Fig. 4 ). In particular, at the ends of the carrier 1 in each case a support plate 53 is fixed, which includes a counterbore 52, with which the support plate 53 bears on a collar 54 of the threaded bolt 51. Each stud 51 is indirectly screwed into the frame of the rotary printing press, in a bushing 55 which is screwed to a side plate 56 which is fixed in the frame of the rotary printing press. Centrally to the counterbore 52, the support plate 53 still has a through hole 57 into which a cylindrical projection 58 of the sleeve 55 projects. From this bore 57 performs a counterbore 52 with detected Ausschlitzung 59 to the edge of the support plate 53rd

Die Arbeitsstellung der Vorrichtung wird mittels jeweils einer in die Tragplatten 53 eingeschraubten Schraube 60, die zur Achse 50 beabstandet ist, fixiert. Jede Schraube 60 ragt mit einem Ansatz in eine Fixierplatte 61, die eine Justierung des Anstellwinkels α der Vorrichtung an dem Formzylinder 20 ermöglichend einstellbar am Seitenblech 56 angeschraubt ist.The working position of the device is fixed by means of one screwed into the support plates 53 screw 60, which is spaced from the axis 50. each Screw 60 protrudes with a projection into a fixing plate 61, which is an adjustment of the angle of attack α of the device on the forme cylinder 20 enabling adjustable on the side plate 56 is screwed.

Längsseitig an dem Träger 1 ist ein Bedienkanal 62 angeordnet (Fig. 2, 3), der Sensoren 63 zur Signalisierung des Öffnungszustandes der Öffnungsklappen 42 bis 45 sowie jedem Bereich einer Druckform 21 bis 24 zugeordnet einen Bedienschalter 64 zur Steuerung eines Wechselprozesses der Druckformen 21 bis 24 enthält. Der Sensor 63 kann beispielsweise ein Magnetfeld des Kolbens 16 desjenigen Arbeitszylinders 2 bis 13 abtasten, der über die Koppel 47 die Öffnungsklappe 42 bis 45 antreibt. Die Elemente des Bedienkanals 62 sind symmetrisch angeordnet. Weiterhin sind die Schlauchanschlüsse und Anschlüsse für die elektrischen Leitungen wahlweise an jedem Ende des Bedienkanals 62 herausführbar. Dies gestattet eine Vorinstallation aller Bauelemente. Außerdem kann der Bedienkanal 62 unabhängig von der Einbaulage der Vorrichtung auf der dem Drucker zugewandten Seite aufgeschraubt werden. Durch diese Möglichkeiten des Zusammenbaus des Bedienkanals 62 und der Vorrichtung können vorteilhaft alle geforderten Einbauvarianten realisiert werden.Longitudinally on the carrier 1, an operating channel 62 is arranged ( Fig. 2 . 3 ), the sensors 63 for signaling the opening state of the opening flaps 42 to 45 and each area of a printing form 21 to 24 associated with an operating switch 64 for controlling a changing process of the printing plates 21 to 24 contains. The sensor 63 can, for example, scan a magnetic field of the piston 16 of that working cylinder 2 to 13, which drives the opening flap 42 to 45 via the coupling 47. The elements of the control channel 62 are arranged symmetrically. Furthermore, the hose connections and connections for the electrical lines can be brought out optionally at each end of the control channel 62. This allows pre-installation of all components. In addition, the operating channel 62 can be screwed independently of the installation position of the device on the printer-facing side. By means of these possibilities of assembling the operating channel 62 and the device, all the required installation variants can advantageously be realized.

Gemäß Fig. 2 ist die Vorrichtung mit einem spitzen Anstellwinkel α an dem Formzylinder 20 angestellt. Als Anstellwinkel α wird der Winkel zwischen der Schubrichtung eines Arbeitszylinders 2 bis 13 und der Tangente an den Formzylinder 20 im Anstellpunkt der Andrückrolle 19 definiert, gemessen an der Unterseite der Vorrichtung. Die Leiste 49 ist so am Schenkel 48 des Schutzgehäuses 41 angeschraubt, dass sich ein nur kleiner Einlaufspalt zum Formzylinder 20 einstellt. Im Vergleich dazu ist gemäß Fig. 3 die Vorrichtung mit einem stumpfen Anstellwinkel α am Formzylinder 20 angeordnet. Hier ist die Leiste 49 entsprechend versetzt am Schenkel 48 angeschraubt, um wiederum einen kleinen Einlaufspalt zu erhalten. Es wurde außerdem die Vorrichtung näher an dem Zylinder 20 angeordnet, das heißt, es wird mit einem kürzeren Anstellweg der Andrückrollen 19 gearbeitet, um mit der zugehörigen Position der geöffneten Öffnungsklappe 42 die gewünschte Größe des Einlaufspaltes an der Öffnungsklappe 42 einzustellen. Der ausgefahrene Zustand der Andrückrolle 19, das heißt ihr Anlagezustand am Formzylinder 20, ist in den Figuren 2 und 3 strichpunktiert dargestellt.According to Fig. 2 the device is employed with an acute angle of attack α on the forme cylinder 20. As the angle of attack α, the angle between the thrust direction of a working cylinder 2 to 13 and the tangent to the forme cylinder 20 is defined in the setting point of the pressure roller 19, measured at the bottom of the device. The strip 49 is screwed to the leg 48 of the protective housing 41 so that only a small inlet gap to the forme cylinder 20 is established. By comparison, according to Fig. 3 the device with an obtuse angle α on the forme cylinder 20 is arranged. Here, the bar 49 is screwed correspondingly offset on the leg 48, in turn, to obtain a small inlet gap. In addition, the device has been arranged closer to the cylinder 20, that is, it is worked with a shorter Anstellweg the pressure rollers 19 to set the desired size of the inlet gap on the opening flap 42 with the associated position of the opened opening flap 42. The extended state of the pressure roller 19, that is their investment state on the forme cylinder 20 is in the Figures 2 and 3 shown in phantom.

Für gewisse Bedienvorgänge, beispielsweise das Wechseln von Gummitüchern oder das Aus- und Einbauen von Farb- und Feuchtwalzen und deren Justierung, kann die Vorrichtung geschwenkt oder ausgebaut werden. Nach Lockern der Schrauben 60 und Herausdrehen ihres Ansatzes aus den Fixierpiatten 61 (Fig. 5) ist die Vorrichtung auf dem jeweiligen Bund 54 der Gewindebolzen 51 um die Achse 50 schwenkbar (Fig. 4). Nach Herausdrehen des Bundes 54 der Gewindebolzen 51 aus dem Bereich der Senkbohrungen 52 kann die Vorrichtung über die Ausschlitzungen 59 aus dem Bereich der Gewindebolzen 51 gezogen und aus der Rotationsdruckmaschine entnommen werden.For certain operations, such as changing blankets or the removal and installation of inking and dampening rollers and their adjustment, the device can be pivoted or removed. After loosening the screws 60 and unscrewing their approach from the Fixierpiatten 61 ( Fig. 5 ), the device on the respective collar 54 of the threaded bolt 51 is pivotable about the axis 50 ( Fig. 4 ). After unscrewing the collar 54 of the threaded bolt 51 from the region of the countersunk holes 52, the device can be pulled out of the region of the threaded bolt 51 via the cutouts 59 and removed from the rotary printing press.

Das Andrücken der Druckform 21 bis 24 erfolgt durch Ausfahren der ihr zugeordneten Andrückrollen 19 gegen den Formzylinder 20 im Rahmen eines Plattenwechselvorganges, der über die Maschinensteuerung oder an den Bedienschaltern 64 ausgelöst werden kann. Das Aus- und Einfahren der Andrückrollen 19 geschieht durch eine gezielte Beaufschlagung der Arbeitszylinder 2 bis 13, die mittels einer Ventilsteuereinheit 65 erfolgt (Fig. 6). Der Ventilsteuereinheit 65 wird Druckluft mit drei verschiedenen Drücken zugeführt, und zwar mit

  • p1 ≈ 1 bar
  • p2 ≈ 5 bar
  • p3 ≈ 3 bar.
The pressing of the printing forme 21 to 24 takes place by extending the associated pressure rollers 19 against the forme cylinder 20 in the context of a plate changing operation that can be triggered via the machine control or on the control switches 64. The extension and retraction of the pressure rollers 19 is done by a targeted actuation of the working cylinder 2 to 13, which takes place by means of a valve control unit 65 ( Fig. 6 ). The valve control unit 65 is supplied with compressed air at three different pressures, with
  • p1 ≈ 1 bar
  • p2 ≈ 5 bar
  • p3 ≈ 3 bar.

Um alle Andrückrollen 19 im eingefahrenen Zustand zu halten, wird dem ersten Kanal 25 Druckluft mit dem Druck p1 zugeführt. In allen Arbeitszylindern 2 bis 13 wird dabei eine einziehende Kraft F1 erzeugt. Um beispielsweise die den Druckformen 21 und 22 zugeordneten Andrückrollen 19 gegen diese und den Formzylinder 20 auszufahren (der Zustand ist in Fig. 1 gezeigt), wird den Kanälen 30 und 31 Druckluft mit dem Druck p2 zugeführt, die in den Druckräumen 28 für das Ausfahren in den Arbeitszylinder 2 bis 7 eine ausfahrende Kraft F2 erzeugt, die größer als die Kraft F1 ist. Für das Einfahren der den Druckformen 21 und 22 zugeordneten Andrückrollen 19 werden die Kanäle 30 und 31 druckfrei geschaltet. Dies bewirkt, dass die in den Druckräumen 29 für das Einfahren der Andrückrollen 19 der Arbeitszylinder 2 bis 7 wirkende Kraft F1 die Kolben 16 einzieht. Vorteilhaft ist es jedoch, wenn nunmehr an den ersten Kanal 25 Druckluft mit dem Druck p3 anqelegt wird, wobei in den Arbeitszylindern 2 bis 7 eine einziehende Kraft F3 erzeugt wird, die kleiner als die Kraft F2 ist. Trotz Wirkens der Kraft F3 üben gegebenenfalls weitere an den Formzylinder 20 angestellte Andrückrollen 19 weiterhin ausreichend ihre Andrückfunktion aus. Die Kräfte sind beispielsweise bemessen zu F1 ≈ 10 N, F2 ≈ 120 N und F3 ≈ 50 N.To keep all pressure rollers 19 in the retracted state, the first channel 25 compressed air is supplied to the pressure p1. In all working cylinders 2 to 13 while a retracting force F1 is generated. To extend, for example, the pressure rollers 21 and 22 associated pressure rollers 19 against these and the forme cylinder 20 (the state is in Fig. 1 shown), the ducts 30 and 31 is supplied with compressed air at the pressure p2, which generates in the pressure chambers 28 for the extension into the working cylinder 2 to 7 an extending force F2, which is greater than the force F1. For the retraction of the printing plates 21 and 22 associated pressure rollers 19, the channels 30 and 31 are switched pressure-free. This causes the force F1 acting in the pressure chambers 29 for retracting the pressure rollers 19 of the working cylinders 2 to 7 to retract the pistons 16. It is advantageous, however, if now attached to the first channel 25 compressed air at the pressure p3 is, wherein in the working cylinders 2 to 7 a retracting force F3 is generated, which is smaller than the force F2. In spite of the action of the force F3, further pressure rollers 19 that are attached to the forme cylinder 20 may continue to exert sufficient pressure. For example, the forces are given as F1 ≈ 10 N, F2 ≈ 120 N and F3 ≈ 50 N.

Für den Fall, dass nur eine Druckform, z. B. die Druckform 21, gewechselt werden soll und das Spannsystem des Formzylinders 20 gleichzeitig eine zweite Druckform 22 freigibt, wird letztere durch die zugehörigen Andrückrollen 19 weiterhin sicher auf dem Formzylinder 20 gehalten und mit dem Aufspannen der neuen Druckform 21 vom Spannsystem des Formzylinders 20 wieder mit festgespannt. Andererseits ist es möglich, bei Formzylindern 20 mit getrennten Spannsystemen pro Druckform 21 bis 24 durch Speisung des entsprechenden Kanals 30 bis 33 lediglich bei nur einer Druckform 21 bis 24 die Andrückrollen 19 anzustellen.In the event that only one printing form, z. B. the printing plate 21, to be changed and the clamping system of the forme cylinder 20 simultaneously releases a second printing plate 22, the latter is still held securely on the forme cylinder 20 by the associated pressure rollers 19 and with the clamping of the new printing plate 21 from the clamping system of the forme cylinder 20 again with tightened. On the other hand, it is possible to use the pressure rollers 19 in the form of cylinders 20 with separate clamping systems per printing plate 21 to 24 by feeding the corresponding channel 30 to 33 only in one printing plate 21 to 24.
