Description

Die Erfindung betrifft eine Bogen-Rotationsdruckmaschine zur Herstellung von einseitigem Mehrfarbendruck oder Schön- und Widerdruck in Reihenbauart mit mindestens einer Wendeeinrichtung sowie Einrichtungen zur Verarbeitung sowohl von Papier als auch von Karton.The invention relates to a sheet-fed rotary printing machine for the production of single-sided multi-color printing or face and face printing in a row design with at least one turning device and devices for processing both paper and cardboard.

Eine Mehrfarben-Bogenrotationsdruckmaschine der oben umrissenen Art ist bereits aus der DE-OS 24 52 167 bekannt. Der Gegendruckzylinder jedes Druckwerkes dieser Maschine und der zwischen zwei Druckwerken angeordnete Wendezylinder haben doppelten Durchmesser. Im Tangentenpunkt beider Zylinder erfaßt ein am Wendezylinder vorgesehenes Saugersystem die Hinterkante des auf der glatten Bogenführungsfläche des Gegendruckzylinders liegenden frisch bedruckten Bogens. Nach Einschwenken innerhalb des Umfangs des Wendezylinders übergibt das Saugersystem die erfaßte Bogenhinterkante an ein Greifersystem, welches daraufhin während der weiteren Drehbewegung des Wendezylinders wieder ausschwenkt und den Bogen nunmehr mit der Hinterkante voran an das Greifersystem des nachfolgenden Gegendruckzylinders übergibt. Zur Erzielung einer registerhaltigen Bogenübergabe ist das Saugersystem als Teil einer Koppel einer Doppelschwinge ausgeführt.A multi-color sheet-fed rotary printing press of the type outlined above is already known from DE-OS 24 52 167. The impression cylinder of each printing unit of this machine and the turning cylinder arranged between two printing units are double in diameter. At the tangent point of both cylinders, a suction system provided on the turning cylinder detects the rear edge of the freshly printed sheet lying on the smooth sheet guiding surface of the impression cylinder. After swiveling in within the circumference of the turning cylinder, the suction system transfers the detected sheet trailing edge to a gripper system, which then swings out again during the further rotational movement of the turning cylinder and now transfers the sheet with the trailing edge first to the gripper system of the subsequent impression cylinder. In order to achieve a sheet transfer that is in register, the suction system is designed as part of a coupling of a double swing arm.

Wegen der relativ großen Durchmesser der bogenführenden Zylinder ist die bekannte Mehrfarben-Bogenrotationsdruckmaschine grundsätzlich zwar zur Verarbeitung von Karton geeignet. Da jedoch das Abnehmen der Bogenhinterkante von der glatten Gegendruckfläche des Druckzylinders mittels eines Saugersystems erfolgen muß, ist während des Übergabevorganges der Bogenhinterkante an das Greifersystem des Wendezylinders trotz der Verwendung einer Doppelschwinge ein Abknicken des hinteren Bogenbereiches unvermeidlich, wodurch die Verarbeitung von dickerem Karton, wenn überhaupt, nur in sehr niedrigen Geschwindigkeitsbereichen möglich ist. Das erwähnte Abknicken der Bogenhinterkante verursacht nämlich wegen der Steifigkeit des Kartons bei höheren Maschinenleistungen in zunehmendem Ausmaß ein Abreißen des Bogens vom Saugersystem.Because of the relatively large diameter of the sheet-guiding cylinders, the known multi-color sheet-fed rotary printing press is basically suitable for processing cardboard. However, since the trailing edge of the sheet must be removed from the smooth counter-pressure surface of the impression cylinder by means of a suction system, a buckling of the rear sheet area is inevitable during the transfer process of the trailing edge of the sheet to the gripper system of the turning cylinder, despite the use of a double rocker arm, which means that processing thicker cardboard, if at all , only in very low speed ranges is possible. The above-mentioned kinking of the trailing edge of the sheet increasingly causes the sheet to be torn off the suction system due to the stiffness of the carton at higher machine outputs.

Aus der DE-AS 23 05 132 ist des weiteren eine Bogenwendevorrichtung für Rotations-Druckmaschinen in Reihenbauart bekannt, bei der die Druckzylinder aufeinanderfolgender Druckwerke durch eine einzige Bogenübergabetrommel verbunden sind. Zum Wenden des Bogens sind zwei Paar aus zwei zusammenwirkenden Klemmgreiferreihen bestehende Greifersysteme in dem Druckzylinder angeordnet, welcher der Bogenübergabetrommel in Transportrichtung folgt. Druckzylinder und Bogenübergabetrommeln haben doppelten Durchmesser. Oberhalb der Bogenübergabetrommel sind Saugkästen vorgesehen, die den zu wendenden Bogen geringfügig von der Mantelfläche der Bogenübergabetrommel abheben, sobald eine Klemmgreiferreihe des nachfolgenden Druckzylinders die Bogenhinterkante erfaßt hat. Während des Wendevorganges, d.h. während der Übergabe der Bogenhinterkante von -dem einen Greifersystem an das andere, wird der zu wendende Bogen von den Saugkästen straff gehalten. Zwar saugen die Saugkästen die nicht bedruckte Seite des Bogens an, sobald aber die Greifersysteme des Druckzylinders nach dem Wendevorgang die nunmehr hintere Bogenkante von dem letzten Saugkasten abzieht, kann die bedruckte Unterseite des Bogens entweder auf die Oberfläche der Bogenübergabetrommel oder auf die Mantelfläche des nunmehr den Bogen transportierenden Druckzylinders aufschlagen, wodurch ein Verschmieren des Druckbildes unvermeidbar ist. Abgesehen von diesem Nachteil läßt sich mit den zwei Greiferreihen, die bei der jeweiligen Bogenwendung in Aktion treten, die Bogenhinterkante kaum ohne Abknicken übergeben. Damit erhielte ein dickerer Karton bleibende Verformungen, die nicht hingenommen werden können und außerdem Betriebsstörungen verursachen.From DE-AS 23 05 132 a sheet turning device for rotary printing presses in series is also known, in which the printing cylinders of successive printing units are connected by a single sheet transfer drum. To turn the sheet, two pairs of gripper systems consisting of two interacting rows of clamping grippers are arranged in the printing cylinder, which follows the sheet transfer drum in the transport direction. Printing cylinders and sheet transfer drums are double in diameter. Above the sheet transfer drum, suction boxes are provided which slightly lift the sheet to be turned from the outer surface of the sheet transfer drum as soon as a row of clamping grippers of the subsequent printing cylinder has gripped the trailing edge of the sheet. During the turning process, i.e. During the transfer of the trailing edge of the sheet from one gripper system to the other, the sheet to be turned is kept taut by the suction boxes. Although the suction boxes suck on the non-printed side of the sheet, as soon as the gripper systems of the printing cylinder after the turning process pulls the rear sheet edge from the last suction box, the printed underside of the sheet can either be on the surface of the sheet transfer drum or on the lateral surface of the now Open the sheet transporting printing cylinder, whereby smearing of the printed image is inevitable. Apart from this disadvantage, the trailing edge of the sheet can hardly be transferred without kinking with the two rows of grippers that come into action when the sheet is turned. This would result in permanent deformation of a thicker cardboard box, which cannot be accepted and which also cause malfunctions.

Aufgabe der Erfindung ist die Schaffung einer umstellbaren Hochleistungs-Bogen-Rotationsoffsetdruckmaschine der eingangs genannten Gattung für die abschmierfreie Verarbeitung von Papier bis zu dickem Karton.The object of the invention is to provide a convertible high-performance sheet-fed rotary offset printing machine of the type mentioned at the outset for the smudge-free processing of paper up to thick cardboard.

Die Lösung dieser Aufgabe beschreibt Anspruch l. Speichertrommel und Wendzylinder weisen vorzugsweise doppelten Durchmesser auf. In dem Druckwerk, dessen Druckzylinder als Speichertrommel ausgeführt ist, wird der zugeordnete Gummizylinder zweckmäßigerweise abgestellt.The solution to this problem is described in claim 1. Storage drum and turning cylinder are preferably double in diameter. In the printing unit, the printing cylinder of which is designed as a storage drum, the associated blanket cylinder is expediently parked.

Durch die Umrüstbarkeit eines Druckzylinders in eine Speichertrommel müssen beim Wendevorgang zur Abnahme der Bogenhinterkante keine Saugersysteme Verwendung finden, da eine Speichertromael keine durchgehende Bogenauflagefläche aufweist und somit die Greifer selbst bei verschiedenen Bogenlängen die Hinterkante des zu wendenden Bogens erfassen können. Die Verwendung von Zangengreifersystemen in dem Wendezylinder gewährleistet darüberhinaus ein abknickfreies Führen der Bogenhinterkante während des gesamten Wendevorganges. Alle drei Maßnahmen, die Bogenführung'mit Zylindern doppelten Durchmessers, Umrüstung des Druckzylinders auf eine Speichertrommel und der Einsatz von Zangengreifern ermöglicht ein paßgenaues Drucken von dickem Karton sowohl nach dem einseitigen Mehrfarben- als auch nach dem Schön- und Widerdruckverfahren bei hohen Druckgeschwindigkeiten. Alle Druckwerkseinheiten, selbst diejenigen, die auf eine Wendeeinrichtung umrüstbar sind, weisen gleiche Seitenteile auf.Due to the convertibility of a printing cylinder into a storage drum, no suction systems need to be used during the turning process to remove the trailing edge of the sheet, since a storage drum does not have a continuous sheet contact surface and the grippers can therefore grasp the trailing edge of the sheet to be turned even with different sheet lengths. The use of pliers gripper systems in the turning cylinder also ensures that the trailing edge of the sheet is guided without kinks during the entire turning process. All three measures, sheet guiding with double-diameter cylinders, conversion of the printing cylinder to a storage drum and the use of pliers grippers enable the precise printing of thick cardboard using both the single-sided multi-color as well as the perfect and reverse printing process at high printing speeds. All printing unit units, even those that can be converted to a turning device, have the same side parts.

Zur Vermeidung von Abschmieren der bedruckten Bogenseiten bei Schön-und Widerdruck sind zumindest die Bogenführungsflächen des dem Wendezylinder unmittelbar folgenden Druckzylinders mit farbabgebenden Aufzügen versehen. Diese Aufzüge weisen eine strukturierte Bogentragfläche auf und sind aus einem verschleißfesten, chemisch beständigen, farbabgabefreudigen Material hergestellt, wie beispielsweise Nickel oder Chrom.In order to avoid smearing of the printed sheet sides in the case of perfect and reverse printing, at least the sheet guide surfaces of the printing cylinder immediately following the reversing cylinder are provided with ink-releasing elevators. These lifts have a structured arch support surface and are made of a wear-resistant, chemically resistant, color-friendly material, such as nickel or chrome.

In vorteilhafter Ausgestaltung der Erfindung können die Bogenführungsflächen eines umrüstbaren Druckzylinders mit herausnehmbaren, stabilen Schalen bestückt sein.In an advantageous embodiment of the invention, the sheet guiding surfaces of a convertible impression cylinder can be equipped with removable, stable shells.

Um ein Verrutschen oder Vorfallen dünnerer Bogen zu vermeiden, können in den Schalen wahlweise einschaltbare, an einen Unterdruckerzeuger angeschlossene Saugkaxmern vorgesehen sein, die über Saugbohrungen in der Mantelfläche der Schale mit der Atmosphäre in Verbindung stehen und den jeweils hinteren Bereich der Bogen verschiedenen Formats durch Ansaugen am Verrutschen oder Vorfallen hindern.In order to prevent slipping or slipping of thinner sheets, suction cups that can be switched on and are connected to a vacuum generator can be provided in the trays, which are connected to the atmosphere via suction holes in the lateral surface of the tray and the respective rear area of the sheets of different formats by suction prevent slipping or falling.

In einer vorteilhaften Ausführungsform der Erfindung sind bei Ausbildung des Druckzylinders als Speichertrommel statt einer Schale zwei zueinander auf das zu verarbeitende Bogenformat einstellbare Gruppen von Bogentragsegmenten vorgesehen. Dabei kann eine Gruppe der Bogentragsegmente mit der Greiferbrücke zum Halten der Bogenvorderkante und die andere Gruppe mit einem Saugersystem zum Halten der Bogenhinterkante verbunden sein. Selbstredend muß der bogentragende Durchmesser der Bogentragsegmente identisch dem Durchmesser sein, den die in den Druckzylinder eingebauten Schalen aufweisen.In an advantageous embodiment of the invention, when the printing cylinder is designed as a storage drum, instead of a shell, two groups of sheet support segments that can be adjusted to the sheet format to be processed are provided. One group of the sheet support segments can be connected to the gripper bridge for holding the leading edge of the sheet and the other group can be connected to a suction system for holding the trailing edge of the sheet. Of course, the arch-carrying diameter of the arch-supporting segments must be identical to the diameter that the shells installed in the pressure cylinder have.

Die Erfindung wird im folgenden Anhang der Zeichnung erläutert.The invention is explained in the following appendix of the drawing.

Es zeigt:

  • Fig. 1 eine Fünffarben-Bogenrotationsdruckmaschine nach der Erfindung mit einer Wendeeinrichtung,
  • Fig. 2 einen Ausschnitt aus Fig. 1 und
  • Fig. 3 eine Sechsfarben-Bogenrotationsdruckmaschine mit zwei Wendeeinrichtungen.
It shows:
  • 1 is a five-color sheet-fed rotary printing press according to the invention with a turning device,
  • Fig. 2 shows a detail from Fig. 1 and
  • Fig. 3 shows a six-color sheet-fed rotary printing press with two turning devices.

Die Bogenrotationsdruckmaschine nach Fig. 1 ist für Fünffarben-Schöndruck oder für je Zweifarben-Schön-und Widerdruck vorgesehen. Sie weist fünf Druckwerke 1-5 auf. Dem Druckwerk 1 ist der Bogenanleger 6 vorgeschaltet. Dieser führt die einem Anlegestapel 7 entnommenen Bogen einer Bogenanlegetrommel 8 zu, die in den Seitenwänden des Druckwerkes 1 gelagert ist. Sie übergibt den Bogen an den Druckzylinder 9 des ersten Druckwerkes, der doppelten Durchmesser aufweist. Gummizylinder 10 und Plattenzylinder 11 haben dagegen nur einfachen Durchmesser. Der Druckzylinder 9 ist also mit zwei Bogenführungsflächen versehen. Er übergibt den jeweils bedruckten Bogen an die Bogenübergabetrommel 12 des Druckwerkes 2.The sheet-fed rotary printing machine according to FIG. 1 is provided for five-color face printing or for two-color face and reverse printing. It has five printing units 1-5. The sheet feeder 6 is connected upstream of the printing unit 1. This feeds the sheets taken from a stack 7 to a sheet feed drum 8 which is mounted in the side walls of the printing unit 1. It transfers the sheet to the printing cylinder 9 of the first printing unit, which has a double diameter. Rubber cylinder 10 and plate cylinder 11, on the other hand, have only a simple diameter. The printing cylinder 9 is therefore provided with two sheet guiding surfaces. It transfers the respectively printed sheet to the sheet transfer drum 12 of the printing unit 2.

In den Seitenwänden des Druckwerkes 2 sind vier Zylinder gelagert. Zunächst einmal sind es, genau wie im Druckwerk 1, die Platten- 11 und Gummizylinder 10. Die Bogenübergabetrommel 12 arbeitet mit dem Druckzylinder 13 zusammen. Sowohl die Bogenübergabetrommel 12 als auch der Druckzylinder 13 haben doppelten Durchmesser. Das nachfolgende Druckwerk 3 weist gleichfalls eine Bogenübergabetrommel 12 auf sowie natürlich Gummizylinder 10 und Plattenzylinder 11. Der Druckzylinder des Druckwerkes 3 hingegen ist auf eine Speichertrommel 14 umgerüstet. Der Gummizylinder 10 ist von der Mantelfläche der Speichertrommel 14 abgestellt und die beiden Bogenführungsflächen der erwähnten Speichtertrommel 14 bestehen aus je zwei Gruppen von kammartig ineinander verschiebbaren Bogentragsegmenten. Eine Gruppe dieser Bogentragsegmente ist jeweils mit der Greiferbrücke 15 fest verbunden, die andere Gruppe mit dem Saugersystem 16. Durch Verschieben der letztgenannten Gruppe der Bogentragsegmente um die Drehachse der Speichertrommel 14 kann das Saugersystem 16 dem Bogenformat jeweils angepaßt werden, so daß es stets das Bogenende erfaßt und aufgrund seiner besonderen Ausbildung eine Straffung des Bogens bewirkt.Four cylinders are mounted in the side walls of the printing unit 2. First of all, just like in the printing unit 1, there are the plate and rubber cylinders 10. The sheet transfer drum 12 works together with the printing cylinder 13. Both the sheet transfer drum 12 and the printing cylinder 13 are double in diameter. The following printing unit 3 likewise has a sheet transfer drum 12 and, of course, rubber cylinder 10 and plate cylinder 11. The printing cylinder of the printing unit 3, however, is converted to a storage drum 14. The rubber cylinder 10 is set down from the outer surface of the storage drum 14 and the two sheet guiding surfaces of the storage drum 14 mentioned each consist of two groups of sheet support segments which can be moved into one another like a comb. A group of these arch support segments is firmly connected to the gripper bridge 15, the other group to the suction system 16. By moving the latter group of arch support segments around the axis of rotation of the storage drum 14, the suction system 16 can be adapted to the sheet format, so that it is always the end of the sheet detected and due to its special training causes a tightening of the bow.

In dem Druckwerk 4 sind gleichfalls wie in den voraufgehenden Druckwerken 2 und 3 vier Zylinder untergebracht, nämlich Gummizylinder 10, Plattenzylinder 11 und Druckzylinder 13 mit doppeltem Durchmesser. Statt der Bogenübergabetrommel 12 ist ein Wendezylinder 18 vorgesehen. Er ist mit zwei Zangengreifersystemen 19, die je nach Einstellung der Fünffarben-Bogenrotationsdruckmaschine entweder die Bogenvorderkante im Schöndruckverfahren oder die Bogenhinterkante im Schön- und Widerdruckverfahren erfassen. Das letzte Druckwerk 5 weist dieselbe Zylinderanordnung wie Druckwerk 2 auf, d.h. es hat die Bogenübergabetrommel 12 mit doppeltem Durchmesser, den Druckzlyinder 13 mit gleichfalls doppeltem Durchmesser und die Gummi- 10 sowie Plattenzylinder 11. Dem Druckwerk 5 schließt sich der Bogenausleger 20 an, dessen Auslagetrommel 21 mit doppeltem Durchmesser versehen ist, und den entweder fünffach oder an beiden Seiten zweifach bedruckten Bogen vom Druckzylinder 13 des Druckwerkes 5 übernimmt. Ein Kettenausleger 22 fördert den bedruckten Bogen auf den Auslagestapel 23.As in the preceding printing units 2 and 3, four cylinders are accommodated in the printing unit 4, namely blanket cylinders 10, plate cylinders 11 and printing cylinders 13 with a double diameter. Instead of the sheet transfer drum 12, a turning cylinder 18 is provided. It is equipped with two pliers gripper systems 19 which, depending on the setting of the five-color sheet-fed rotary printing press, capture either the leading edge of the sheet in the straight printing process or the trailing edge of the sheet in the face and reverse printing processes. The last printing unit 5 has the same cylinder arrangement as printing unit 2, i.e. it has the sheet transfer drum 12 with a double diameter, the printing cylinder 13 with a double diameter and the rubber 10 and plate cylinder 11. The printing unit 5 is followed by the sheet delivery 20, the delivery drum 21 is provided with a double diameter, and either five times or more two-sided printed sheets from the printing cylinder 13 of the printing unit 5 takes over. A chain boom 22 conveys the printed sheet onto the delivery stack 23.

Die in Figur 1 gezeigte Bogenrotationsdruckmaschine bedruckt aufgrund der Anordnung der Speichertrommel 14 und des Wendezylinders 18 den Bogen sowohl an der Unter- als auch an der Oberseite je zweimal. Durch die Kette der relativ großen Bogenfuhrungszylinder 9, 12, 13, 14, 18 und 21 kann diese Maschine sehr gut dicken Karton verarbeiten, dies um so mehr, als die Zangengreifersysteme 19 die Bogenhinterkante derart erfassen können, daß ein Abknicken des relativ steifen Kartons nicht erfolgt. Aber auch relativ dünne Papiere können sehr gut verarbeitet werden, da das Saugersystem 16 der Speichertrommel 14 diese dünnen Bogen straff spannt und eine paßgenaue Übergabe der Bogenhinterkante an die Zangengrifersysteme 19 gewährleistet. Besonderer Vorzug dieser Maschine ist, daß die Druckwerke 2, 3, 4 und 5 hinsichtlich ihrer Seitengestelle absolut gleich ausgeführt werden können.The sheet-fed rotary printing machine shown in FIG. 1 prints the sheet twice on both the bottom and the top due to the arrangement of the storage drum 14 and the reversing cylinder 18. Due to the chain of the relatively large sheet guide cylinders 9, 12, 13, 14, 18 and 21, this machine can process very thick cardboard, all the more because the gripper systems 19 can grasp the trailing edge of the sheet in such a way that the relatively rigid cardboard does not kink he follows. However, relatively thin papers can also be processed very well, since the suction system 16 of the storage drum 14 tightens these thin sheets and ensures that the trailing edge of the sheet is transferred to the gripper systems 19 with a precise fit. A particular advantage of this machine is that the printing units 2, 3, 4 and 5 can be made absolutely identical in terms of their side frames.

Der in Figur 2 gezeigte Ausschnitt aus Figur 1 betrifft die drei Druckwerke 2, 3 und 4. Die Ausbildung aller drei Druckwerke ist gleich mit einer einzigen Ausnahme. Die Speichertrommel 14 ist in einen Druckzylinder 25 umgerüstet worden. Die Umrüstung besteht darin, daß statt der o.e. kammartig ineinander greifenden Gruppen von bogentragsegmenten je eine stabile Schale 26 vorgesehen ist. Der Außendurchmesser beider Schalen 26 entspricht dem Durchmesser der bogentragenden Fläche der herausgenommenen Bogentragsegmente. Die Schalen 26 sind stabil ausgebildet und leicht herausnehmbar am Kern des Druckzylinders 25 befestigt. Sie können mit Saugkammern versehen sein, die wahlweise einschaltbar an einem nicht dargestellten Unterdruckerzeuger angeschlossen sind. Saugbohrungen in der Mantelfläche der Schalen verbinden die Saugkammern mit der Atmosphäre. Durch Erzeugen eines Unterdruckes in den erwähnten Saugkammern kann der jeweilig von der Schale 26 geführte Bogen nach dem Bedrucken in seinem hinteren Bereich angesaugt werden, damit auch bei der Übernahme der Bogenvorderkante durch das Zangengreifersystem 19 ein Vorfallen oder Durchrutschen des Bogens verhindert wird. Bei Verarbeitung des maximalen Bogenformats kann das bereits in der Speichertrommel 14 verwendete Saugersystem 16 zum Halten des Bogens herangezogen werden. Nach dem Einsetzen der Schalen 26 in den Druckzylinder 25 wird der Gummizylinder 10 des Druckwerkes 3 angestellt. In dieser Schaltstellung ist es möglich, daß die Bogenrotationsdruckmaschine nach Figur 1 einen Bogen fünffarbig bedruckt.The detail shown in Figure 2 from Figure 1 relates to the three printing units 2, 3 and 4. The formation of all three printing units is the same with a single exception. The storage drum 14 has been converted into a pressure cylinder 25. The conversion consists in that instead of the above-mentioned interdigitated groups of arch support segments, a stable shell 26 is provided. The outer diameter of both shells 26 corresponds to the diameter of the arch-bearing surface of the arch-support segments removed. The shells 26 are designed to be stable and are attached to the core of the pressure cylinder 25 in an easily removable manner. They can be provided with suction chambers, which can be optionally connected to a vacuum generator, not shown. Suction bores in the outer surface of the shells connect the suction chambers to the atmosphere. By generating a negative pressure in the said suction chambers of the respective run from the shell 26 sheets can be sucked after printing in its rear region, so that even when the acquisition of the sheet leading edge orfallen a V by the collet gripper system 19 or slippage of the sheet is prevented. When processing the maximum sheet format, the suction system 16 already used in the storage drum 14 can be used to hold the sheet. After inserting the shells 26 into the impression cylinder 25, the rubber cylinder 10 of the printing unit 3 is turned on. In this switch position it is possible for the sheet-fed rotary printing machine according to FIG. 1 to print a sheet in five colors.

Die in Figur 3 dargestellte Sechsfarben-Bogenrotationsdruckmaschine unterscheidet sich von der zuvor beschriebenen lediglich dadurch, daß zwei Wendeeinrichtungen vorgesehen sind. Das erste Druckwerk 31 besitzt einen Druckzylinder 9 mit doppeltem Durchmesser, einen Gummizylinder 10 und einen Plattenzylinder 11 mit einfachem Durchmesser. Die Anlegetrommel 8 erhält die von ihr dem Druckzylinder 9 zugeführten Bogen von dem Bogenanleger 6. Das nächste Druckwerk 32 ist mit einer normalen Bogenübergabetrommel 12, einer Speichertrommel 14, dem Gummizylinder 10 und dem Plattenzylinder 11 bestuckt. Bogenübergabetrommel 12 und Speichertrommel 14 weisen doppelten Durchmesser auf. Der Gummizylinder 10 ist natürlich abgestellt. Das folgende Druckwerk 33 hat einen Wendezylinder 18, einen mit zwei Schalen 26 bestückten umrüstbaren Druckzylinder 25 sowie Gummi- 10 und Plattenzylinder 11. Das nächstfolgende Druckwerk 34 besitzt einen Wendezylinder 18, einen Druckzylinder 13, beide haben doppelten Durchmesser und wie üblich Gummizylinder 10 sowie Plattenzylinder 11.The six-color sheet-fed rotary printing press shown in FIG. 3 differs from the previously described only in that two turning devices are provided. The first printing unit 31 has a printing cylinder 9 with a double diameter, a rubber cylinder 10 and a plate cylinder 11 with a single diameter. The feed drum 8 receives the printing cylinder 9 from it fed sheets from the sheet feeder 6. The next printing unit 32 is equipped with a normal sheet transfer drum 12, a storage drum 14, the rubber cylinder 10 and the plate cylinder 11. Sheet transfer drum 12 and storage drum 14 have a double diameter. The rubber cylinder 10 is of course turned off. The following printing unit 33 has a turning cylinder 18, a convertible printing cylinder 25 equipped with two shells 26, as well as rubber 10 and plate cylinders 11. The next printing unit 34 has a turning cylinder 18, a printing cylinder 13, both have double diameters and, as usual, rubber cylinders 10 and plate cylinders 11.

Die beiden letzten Druckwerke 35 und 36 sind genau gleich ausgebildet, nämlich mit einer gewöhnlichen Bogenübergabetrommel 12, einem Druckzyinder 13 und Gummi- 10 sowie Plattenzylinder 11. Der Bogenausleger 20 entspricht demgemäß der Ausführungsform nach Fig. l, d.h. auch er weist eine Auslagetrommel 21 mit doppeltem Durchmesser auf.The last two printing units 35 and 36 are of exactly the same design, namely with an ordinary sheet transfer drum 12, a printing cylinder 13 and rubber 10 and plate cylinder 11. The sheet delivery 20 accordingly corresponds to the embodiment according to FIG. it also has a delivery drum 21 with a double diameter.

In der dargestellten Ausführung erfolgt im Druckwerk 31 das einfarbige Bedrucken der einen Bogenseite und im Druckwerk 32 aufgrund der Anordnung der Speichertrommel 19 das Wenden des bedruckten Bogens. In den folgenden Druckwerken 33, 34, 35 und 36 wird auf die nunmehr obenliegende Bogenfläche ein Vierfarbenwiderdruck aufgebracht. Um ein Verschmieren der im ersten Druckwerk 31 bedruckten untenliegenden Bogenseite zu verhindern, können die Bogenführungsflächen der Druckzylinder 25 und 13 aller vier Druckwerke 33, 34, 35 und 36 mit farbabgebenden Aufzügen versehen sind, damit ein Verschmieren des vom Druckwerk 31 aufgebrachten Druckes verhindert wird. Findet eine schnelltrocknende Farbe Verwendung, so mag es genügen, wenn die Bogenführungsflächen der Druckzylinder 25 und 13 der Druckwerke 33 und 34 mit solchen Aufzügen bestückt werden. Durch Umrüstung der Speichertrommel 19 des Druckwerks 32 in einen Druckzylinder 25 sowie des Druckzylinders 25 des Druckwerkes 33 in eine Speichertrommel 19, besteht die Möglichkeit eines Zwei- farben-Schön- und eines Dreifarben-Widerdruckes zu erzielen. Für den Fall, daß ein Sechsfarben-Schöndruck gewünscht wird, können beide Druckwerke 32 und 33 mit Druckzylinder 25 bestückt werden. Die in den Fig. 1 bis 3 dargestellten Ausführungsformen können noch insofern eine Abwandlung erfahren, als beispielsweise Druckzylinder 25 und auch Druckzylinder 13 oder Bogenübergabetrommeln 12 und 18 oder Bogenübergabetrommel 12 und 18 dreifachen Durchmesser aufweisen, und demgemäß mit drei Bogenführungsflächen versehen sind.In the embodiment shown, the single-color printing of one sheet side takes place in the printing unit 31 and the printing sheet 32 is turned in the printing unit 32 due to the arrangement of the storage drum. In the following printing units 33, 34, 35 and 36, a four-color counterprint is applied to the sheet surface now on top. In order to prevent smearing of the lower sheet side printed in the first printing unit 31, the sheet guiding surfaces of the printing cylinders 25 and 13 of all four printing units 33, 34, 35 and 36 can be provided with ink-releasing lifts, so that smearing of the print applied by the printing unit 31 is prevented. If a fast-drying ink is used, it may be sufficient if the sheet guiding surfaces of the printing cylinders 25 and 13 of the printing units 33 and 34 are equipped with such elevators. By converting the storage drum 19 of the printing unit 32 into a printing cylinder 25 and the printing cylinder 25 of the printing unit 33 in a storage drum 19, there is the possibility of achieving a two-color perfect and a three-color counterprint. In the event that a six-color fine print is desired, both printing units 32 and 33 can be equipped with printing cylinder 25. The embodiments shown in FIGS. 1 to 3 can also be modified insofar as, for example, impression cylinders 25 and also impression cylinders 13 or sheet transfer drums 12 and 18 or sheet transfer drums 12 and 18 have three times the diameter and are accordingly provided with three sheet guide surfaces.
