Abstract

The printing machine is composed of an indirectly printing printing unit (A), and a sheet transport device (B), composed solely of drums (18, 19, 20, 22, 23, 24), and of a following intaglio printing unit (C). The indirectly printing printing unit (A) has two interacting blanket cylinders (3, 5), each of which is inked with several colors by several plate cylinders (12, 15; 7, 10). The sheets are passed onto one of the blanket cylinders (3) from a carry-over drum (2) and, after passing through the nip between two blanket cylinders (3, 5), thereby being printed on both sides, are taken over by a transfer drum (18) of the sheet transport device. The circumferential region which is located between the carry-over drum (2) and transfer drum (8) and over which the sheet passes extends over at most 180 DEG , preferably less than 150 DEG , so that that free circumferential region of this blanket cylinder not covered by the sheet is available for accommodating several plate cylinders.

Description

Die Erfindung bezieht sich auf eine kombinierte Bogen­rotationsdruckmaschine für Wertscheine, insbesondere Banknoten, gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a combined sheet-fed rotary printing machine for banknotes, in particular banknotes, according to the preamble of patent claim 1.

Eine derartige Druckmaschine ist in der EP-B 0 136 972 beschrieben. Das indirekt druckende Druckwerk dieser bekannten Druckmaschine besteht aus einem von mehreren Offsetplattenzylindern eingefärbten Gummizylinder und einem mit diesem zusammenwirkenden Druckzylinder und erlaubt daher nur eine der Bogenseiten zu bedrucken. Ueberführungstrommel und Uebergabetrommel arbeiten mit dem Druckzylinder zusammen, dessen Bogengreifer einen Bogen von der Ueberführungstrommel übernehmen und ihn unter Anlage am Druckzylinderumfang bis zum Erfassen durch die Greifer der Uebergabetrommel mitnehmen. Dabei ist der zwischen Ueberführungstrommel und Uebergabetrommel liegende Umfangsbereich, in welchem der Bogen auf dem Druckzylinder mitgenommen wird, wesentlich grösser als der halbe Druckzylinderumfang. Ausserdem fungiert die Uebergabetrommel gleichzeitig als Bogenwendetrommel einer Bogenwendevorrichtung und hat aus diesem Grunde eine der Länge zweier Bogen entsprechende Grösse, so dass ihr Durchmesser doppelt so gross ist wie der Durchmesser der Plattenzylinder und der Ueberführungstrommel, welche üblicherweise eine einem einzigen Bogen entsprechende Grösse haben, während der Gummizylinder und der Druckzylinder dem Format dreier Bogen angepasst sind und daher einen dreimal so grossen Durchmesser aufweisen wie die Plattenzylinder und die Ueberführungstrommel.Such a printing press is described in EP-B 0 136 972. The indirectly printing printing unit of this known printing press consists of a rubber cylinder colored by a plurality of offset plate cylinders and a printing cylinder interacting with it and therefore allows only one of the sheet sides to be printed. The transfer drum and the transfer drum work together with the printing cylinder, the sheet grippers of which take over a sheet from the transfer drum and take it along against the circumference of the printing cylinder until they are gripped by the grippers of the transfer drum. The circumferential area between the transfer drum and the transfer drum, in which the sheet is carried on the impression cylinder, is considerably larger than half the impression cylinder circumference. In addition, the transfer drum also functions as a sheet turning drum of a sheet turning device and is therefore of a size corresponding to the length of two sheets, so that its diameter is twice as large as the diameter of the plate cylinder and the transfer drum, which are usually of a size corresponding to a single sheet, while the blanket cylinder and the impression cylinder are adapted to the format of three sheets and therefore have a diameter three times as large as the plate cylinder and the transfer drum.

Die Bogentransportvorrichtung bei der bekannten kom­binierten Druckmaschine besteht, wie erwähnt, aus einer mit dem Druckzylinder des indirekt druckenden Druck­werks zusammenwirkenden Bogenwendetrommel, die als Uebergabetrommel fungiert, einer zur Bogenwendevorrich­tung gehörenden kleinen Trommel, die der Grösse eines Bogens angepasst ist, einer doppelt so grossen Trocknungstrommel, in deren Umfangsnähe eine Trock­nungseinrichtung angeordnet ist, einer das Register korrigierenden Registertrommel sowie einer Transport­trommel, welche die Bogen auf den Druckzylinder des Stichtiefdruckwerks übergibt und deren Grosse, ebenso wie die Grösse der Registertrommel, der Grösse eines Bogens entspricht. Da diese Transportvorrichtung, unter Verzicht auf Kettengreifersysteme, nur mit zusammen­wirkenden Trommeln arbeitet, bei denen der Bogen von einer Trommel unmittelbar auf die folgende Trommel ge­langt, wird während des gesamten Bogentransports zwi­schen dem indirekt druckenden Druckwerk und dem Stich­tiefdruckwerk ein vollkommenes Register mit grosser Zu­verlässigkeit aufrechterhalten, so dass im allgemeinen eine eventuelle Registerkorrektur allenfalls nach einer Bogenwendung erforderlich und dann automatisch von der Registertrommel durchgeführt wird.As mentioned, the sheet transport device in the known combined printing press consists of a sheet turning drum which interacts with the printing cylinder of the indirectly printing printing unit and functions as a transfer drum, a small drum belonging to the sheet turning device which is adapted to the size of a sheet, a drying drum which is twice as large, in the vicinity of which a drying device is arranged, a register drum correcting the register and a transport drum which transfers the sheets to the printing cylinder of the intaglio printing unit and whose size, like the size of the register drum, corresponds to the size of a sheet. Since this transport device, without the need for chain gripper systems, only works with interacting drums, in which the sheet passes directly from one drum to the following drum, a perfect register is maintained with great reliability during the entire sheet transport between the indirectly printing printing unit and the intaglio printing unit. so that a possible register correction is generally necessary after a sheet has been turned and is then carried out automatically by the register drum.

Mit der erwähnten bekannten Druckmaschine kann ent­weder, ohne Wendung der Bogen, ein und dieselbe Bogen­seite mit einem Mehrfarben-Offsetdruck und mit einem Mehrfarben-Stahlstichdruck bedruckt werden oder, bei Wendung der Bogen, die eine Bogenseite einen Mehr­farben-Offsetdruck und die andere Bogenseite einen Mehrfarben-Stahlstichdruck erhalten.With the known printing machine mentioned, one and the same sheet side can either be printed with a multicolor offset print and with a multicolor steel engraving print, without turning the sheets, or, when the sheets are turned, the one sheet side is a multicolor offset print and the other sheet side is a multicolor - received steel engraving print.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine kombinierte Bogenrotationsdruckmaschine der im Oberbegriff des Anspruchs 1 beschriebenen Art unter Beibehaltung einer nur aus Trommeln aufgebauten Bogen­transportvorrichtung so zu gestalten, dass das indirekt druckende Druckwerk im Schön- und Widerdruck arbeiten und auf beiden Bogenseiten je ein Mehrfarbenbild er­zeugen kann.The present invention is based on the object of designing a combined sheet-fed rotary printing press of the type described in the preamble of claim 1 while maintaining a sheet transport device constructed only from drums so that the indirectly printing printing unit works in face and reverse printing and generates a multicolor image on both sides of the sheet can.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Durch die Ausbildung und die Anordnung der Ueberfüh­rungstrommel und der Uebergabetrommel im indirekt druckenden Druckwerk wird der nicht von einem Bogen be­deckte freie Umfangsbereich des zweiten, als Gummizylinder ausgebildeten Zylinders so weit vergrössert, dass längs dieses Umfangsbereichs mehrere, insbesondere drei oder vier Offsetplattenzylinder und ihre Farbwerke installiert werden können, so dass auf einfache Weise ein das indirekt druckende Druckwerk passierender Bogen nicht nur auf seiner dem ersten Gummizylinder zugewandten Seite, sondern auch auf der am zweiten Gummizylinder anliegenden Seite je einen Mehrfarbendruck erhält. Bei diesen Mehrfarbendrucken handelt es sich im Falle von Banknoten vorzugsweise um je einen mehrfarbigen Sicherheitsuntergrund, der auf der einen Bogenseite im Stichtiefdruckwerk durch einen das Hauptmuster darstellenden Mehrfarben-Stahl­stichdruck ergänzt wird. Auf diese Weise sind mit dieser Druckmaschine in einem Arbeitsgang vollständige Banknotendrucke herstellbar, bei denen die Vorderseite ein mehrfarbiges Hauptmuster und einen mehrfarbigen Sicherheitsuntergrund und die Rückseite einen mehrfarbigen Sicherheitsuntergrund aufweist, wie das insbesondere bei Banknoten niedriger Werte häufig üblich ist. Darüberhinaus lässt sich jedoch auch auf der Rückseite ein Hauptmuster dadurch erzeugen, dass wenigstens einer der Plattenzylinder des indirekt druckenden Druckwerks mit einer ein Hauptmuster aufweisenden Nassoffsetdruckplatte, vorzugsweise in Form einer angefeuchteten Tiefdruckplatte, ausgerüstet ist.Due to the design and arrangement of the transfer drum and the transfer drum in the indirectly printing printing unit, the free peripheral area of the second cylinder, which is designed as a rubber cylinder and not covered by an arc, is enlarged to such an extent that several, in particular three or four offset plate cylinders and their inking units are installed along this peripheral area can be, so that a sheet passing through the indirectly printing printing unit receives a multicolor print not only on its side facing the first rubber cylinder, but also on the side adjacent to the second rubber cylinder. In the case of banknotes, these multicolor prints are preferably each a multicolor security background, which is supplemented on one side of the sheet in the intaglio printing unit by a multicolor steel engraving print representing the main pattern. In this way, with this printing machine, complete banknote prints can be produced in one operation, in which the front side has a multicolored main pattern and a multicolored security background and the back side one has a multicolored security background, as is often the case especially with banknotes of low values. In addition, however, a main pattern can also be produced on the back in that at least one of the plate cylinders of the indirectly printing printing unit is equipped with a wet offset printing plate having a main pattern, preferably in the form of a moistened gravure printing plate.

Zweckmässige Ausgestaltungen der Druckmaschine nach der Erfindung ergeben sich aus den abhängigen Ansprüchen. Eine besonders zweckmässige Ausführungsform, gemäss welcher das indirekt druckende Druckwerk konvertierbar ist und auf der einen Bogenseite je nach Einstellung einen Mehrfarben-Offsetdruck oder einen Mehrfarben-­Sammeldruck zu erzeugen erlaubt, wird im Anspruch 11 beschrieben.Appropriate configurations of the printing press according to the invention result from the dependent claims. A particularly expedient embodiment, according to which the indirectly printing printing unit can be converted and on the one side of the sheet, depending on the setting, allows a multicolor offset print or a multicolor collective print to be produced is described in claim 11.

The invention is explained in more detail with reference to the drawings of exemplary embodiments. Show it:
  • FIG. 1 shows a first exemplary embodiment of a combined sheet-fed rotary printing press, in which the indirectly printing printing unit supplies multicolor offset printing on both sides,
  • 2 shows a variant of the printing machine according to FIG. 1 with a different sheet feeding system and a different arrangement of the plate cylinders on the upper blanket cylinder of the indirectly printing printing unit,
  • Figure 3 shows a second embodiment, in which the indirectly printing unit on one sheet side, a multi-color offset printing and on the other sheet side provides a color batch print,
  • FIGS. 4 to 6 show a third exemplary embodiment in which the indirectly printing printing unit is convertible and can assume three different working positions to achieve different printing combinations, the lower printing unit half according to FIG. 4 being a collective printing position, according to FIG. 5 a first offset printing position and according to FIG. 6 a second offset printing position occupies.

Die kombinierte Bogenrotationsdruckmaschine besteht nach Figur 1 aus einem indirekt druckenden Druckwerk A, das die Bogen zuerst durchlaufen, aus einer nachge­schalteten Bogentransportvorrichtung B, die sich aus­schliesslich aus Trommeln zusammensetzt, und aus einem Stichtiefdruckwerk C, in welches die Bogen am Ende der Transportvorrichtung B gelangen.According to FIG. 1, the combined sheet-fed rotary printing press consists of an indirectly printing printing unit A, through which the sheets first pass, a downstream sheet transport device B, which is composed exclusively of drums, and an intaglio printing unit C, into which the sheets arrive at the end of the transport device B.

Das indirekt druckende Druckwerk A, bei dem es sich um ein im Schön- und Widerdruck arbeitendes Druckwerk han­delt, weist zwei zusammenwirkende, senkrecht übereinan­derliegende Gummizylinder 3 und 5 auf, die jeder mit mehreren, Offsetdruckplatten tragenden Plattenzylindern 12, 15 bzw. 7, 10 in Berührung stehen und zwischen denen die Bogen gleichzeitig auf beiden Seiten bedruckt werden. Ueber mehrere Transporttrommeln 1 und eine mit dem Gummizylinder 3 zusammenwirkende Ueberführungs­trommel 2 gelangen die Bogen auf den Gummizylinder 3, von dessen Bogengreifern sie mitgenommen werden. Die Drehrichtung der beiden Gummizylinder 3 und 5 ist durch Pfeile angedeutet. Nachdem ein vom Gummizylinder 3 mit­genommener Bogen die Druckstelle zwischen beiden Gummi­zylindern passiert hat, wird er von einer mit dem Gummizylinder 3 zusammenwirkenden Uebergabetrommel 18 erfasst, welche die erste Transporttrommel der Bogen­transportvorrichtung B darstellt. Der zwischen der Ueberführungstrommel 2 und der Uebergabetrommel 18 liegende Umfangsbereich, in welchem ein Bogen vom Gummizylinder 3 mitgenommen wird, ist höchstens so gross wie dessen halber Umfang und erstreckt sich im betrachteten Beispiel über ungefähr 135°. Allgemein ist es vorteilhaft, wenn sich dieser Umfangsbereich über einen Winkel von weniger als etwa 150° erstreckt.The indirectly printing printing unit A, which is a printing unit working in perfecting and printing, has two interacting, vertically superimposed rubber cylinders 3 and 5, each with a plurality of plate cylinders 12, 15 and 7, 10 in, respectively, carrying offset printing plates Stand in touch and between which the sheets are printed on both sides at the same time. Via several transport drums 1 and a transfer drum 2 which interacts with the rubber cylinder 3, the sheets reach the rubber cylinder 3, from the sheet grippers of which they are taken along. The direction of rotation of the two rubber cylinders 3 and 5 is indicated by arrows. After a sheet entrained by the blanket cylinder 3 has passed the pressure point between the two blanket cylinders, it is transferred from a transfer drum 18 which interacts with the blanket cylinder 3 detected, which represents the first transport drum of the sheet transport device B. The circumferential area between the transfer drum 2 and the transfer drum 18, in which an arc is carried by the rubber cylinder 3, is at most as large as half its circumference and extends in the example under consideration over approximately 135 °. In general, it is advantageous if this peripheral region extends over an angle of less than approximately 150 °.

Die Uebergabetrommel 18 hat den gleichen Durchmesser wie die Ueberführungstrommel 2 und die Plattenzylinder 7, 10 und 12, 15, welche wie üblich kleine, nur eine Druckplatte tragende Zylinder sind, deren Umfangslänge der Grösse eines Bogens angepasst ist. Die Gummizylinder 3 und 5 sind zur Aufnahme je dreier Bogen bestimmt und daher dreimal so gross.The transfer drum 18 has the same diameter as the transfer drum 2 and the plate cylinders 7, 10 and 12, 15, which, as usual, are small cylinders with only one pressure plate, the circumferential length of which is adapted to the size of a sheet. The rubber cylinders 3 and 5 are designed to hold three sheets each and are therefore three times as large.

Aufgrund der Anordnung und Ausbildung der Ueberfüh­rungstrommel 2 und der Uebergabetrommel 18 ist der freie, nicht von einem Bogen bedeckte obere Umfangs­bereich des Gummizylinders 3 wenigstens so gross wie der halbe Zylinderumfang; er erstreckt sich im betrachteten Beispiel über etwa 225° und bietet genügend Platz zur Unterbringung mehrerer Platten­zylinder, im betrachteten Beispiel von vier Platten­zylindern, von denen nach Figur 1 die beiden Plattenzylinder 12 rechts der vertikalen Mittellinie und die beiden Plattenzylinder 15 links der vertikalen Mittellinie des Gummizylinders 3 angeordnet sind.Due to the arrangement and design of the transfer drum 2 and the transfer drum 18, the free upper circumferential area of the blanket cylinder 3, which is not covered by an arc, is at least as large as half the circumference of the cylinder; in the example considered, it extends over approximately 225 ° and offers sufficient space for accommodating a plurality of plate cylinders, in the example considered four plate cylinders, of which, according to FIG. 1, the two plate cylinders 12 to the right of the vertical center line and the two plate cylinders 15 to the left of the vertical center line of the rubber cylinder 3 are arranged.

Im betrachteten Beispiel ist angenommen, dass die Plattenzylinder 12 und 15 Nassoffsetplatten tragen. Diese werden von je einem Farbwerk 13 bzw. 16 einge­färbt und von je einem Feuchtwerk 13′ bzw. 16′ angefeuchtet. Die Farbwerke 13 und die Feuchtwerke 13′ sind in einem Farbwerkgestell 14, die Farbwerke 16 und die Feuchtwerke 16′ in einem Farbwerkgestell 17 untergebracht.In the example considered, it is assumed that the plate cylinders 12 and 15 carry wet offset plates. These are inked by a respective inking unit 13 or 16 and by a dampening unit 13 'or 16' moistened. The inking units 13 and the dampening units 13 'are housed in an inking unit frame 14, the inking units 16 and the dampening units 16' in an inking unit frame 17.

Der andere Gummizylinder 5 arbeitet mit vier Offset­druckplatten tragenden Plattenzylindern zusammen, von denen nach Figur 1 drei Plattenzylinder 7 rechts der vertikalen Mittellinie und ein Plattenzylinder 10 links der vertikalen Mittellinie des Gummizylinders 5 installiert sind. Wiederum ist angenommen, dass diese Plattenzylinder Nassoffsetplatten tragen. Die drei Plattenzylinder 7 arbeiten mit Farbwerken 8 und Feucht­werken 8′ in einem abfahrbaren Farbwerkgestell 9 zusammen, während der Plattenzylinder 10 mit einem Farbwerk 11 und einem Feuchtwerk 11′ zusammenarbeitet.The other rubber cylinder 5 works together with four plate cylinders carrying offset printing plates, of which, according to FIG. 1, three plate cylinders 7 are installed to the right of the vertical center line and one plate cylinder 10 to the left of the vertical center line of the rubber cylinder 5. Again, it is assumed that these plate cylinders have wet offset plates. The three plate cylinders 7 work with inking units 8 and dampening units 8 'in a removable inking unit frame 9, while the plate cylinder 10 works with an inking unit 11 and a dampening unit 11'.

Nach Figur 1 sind ferner in Umfangsnähe der Ueberfüh­rungstrommel 2 und der vorangehenden Transporttrommel 1 Papierstaub-Absaugvorrichtungen 32 vorgesehen; diese auf die einen und die anderen Bogenseiten wirkenden Ab­saugvorrichtungen können auch in Umfangsnähe von wenigstens zwei aufeinanderfolgenden Transporttrommeln 1 angeordnet sein. Im unteren Umfangsbereich des Gummi­zylinders 3 und des Gummizylinders 5 sind ferner auto­matisch arbeitende Gummituch-Waschvorrichtungen 4 bzw. 6 vorgesehen, die natürlich beim Druckbetrieb des Druckwerks eine von den Gummizylindern abgerückte Ausserbetriebsstellung einnehmen.According to FIG. 1, paper dust suction devices 32 are also provided in the vicinity of the circumference of the transfer drum 2 and the preceding transport drum 1; these suction devices acting on the one and the other sides of the sheet can also be arranged in the vicinity of the circumference of at least two successive transport drums 1. In the lower circumferential area of the blanket cylinder 3 and the blanket cylinder 5, automatically operating blanket washing devices 4 and 6 are also provided, which of course assume an out-of-operation position moved away from the blanket cylinders during the printing operation of the printing unit.

Die Transportvorrichtung B weist im betrachteten Beispiel neun Transporttrommeln auf, und zwar die Uebertragungstrommel 18, eine Trommel 19, vier Trommeln 20, in deren Umfangsnähe Trocknungsvorrichtungen 21 zum Trocknen beider bedruckten Bogenseiten angeordnet sind, eine zu einer Bogenwendevorrichtung gehörende Bogen­wendetrommel 22, eine Trommel 23, die als Register­trommel und gleichzeitig als Teil der Bogen­wendevorrichtung fungiert, und eine weitere Trommel 24, welche die Bogen in das Stichtiefdruckwerk C eingibt. Die Trommeln 18, 19, 20, 23 und 24 haben alle die gleiche, einem Bogen angepasste Grösse, während die Bogenwendetrommel 22 der Grösse zweier Bogen angepasst ist und daher einen doppelt so grossen Durchmesser hatIn the example considered, the transport device B has nine transport drums, namely the transfer drum 18, one drum 19, four drums 20, in the circumferential vicinity of which drying devices 21 for drying both printed sheet sides are arranged, a sheet turning drum 22 belonging to a sheet turning device, a drum 23 which functions as a register drum and at the same time as part of the sheet turning device, and a further drum 24 which feeds the sheets into the intaglio printing unit C. The drums 18, 19, 20, 23 and 24 all have the same size adapted to an arc, while the sheet turning drum 22 is adapted to the size of two arcs and therefore has a diameter twice as large

Diese Bogenwendevorrichtung ist bekannt und ihre Funktion wird beispielsweise in der EP-B 0 136 972 erläutert. Wenn ein Bogen, welcher sich auf der im Sinne des Pfeils rotierenden Trommel 22 befindet, nicht gewendet werden soll, dann wird er in üblicher Weise unmittelbar von der Trommel 23 übernommen, indem deren Greifer die Vorderkante des auf der Trommel 22 ankommenden Bogens erfassen. Im Falle einer Bogenwendung wird der Bogen, nachdem er vollständig den Spalt zwischen den Trommeln 22 und 23 passiert hat, an seiner Hinterkante von den schwenkbar an der Trommel 23 montierten und entsprechend gesteuerten Greifern erfasst und im Sinne des geraden Pfeils F auf die Trommel 23 gezogen, wobei die bisherige Bogenhinterkante zur Vorderkante des Bogens wird, der gleichzeitig von den Greifern der Trommel 22 freigegeben wird.This sheet turning device is known and its function is explained for example in EP-B 0 136 972. If a sheet, which is located on the drum 22 rotating in the direction of the arrow, is not to be turned, then it is taken over directly by the drum 23 in the usual manner, in that its grippers grip the leading edge of the sheet arriving on the drum 22. In the event of a sheet turning, the sheet, after it has completely passed the gap between the drums 22 and 23, is gripped at its rear edge by the grippers, which are pivotably mounted on the drum 23 and controlled accordingly, and are drawn onto the drum 23 in the direction of the straight arrow F. , with the previous trailing edge of the sheet becoming the leading edge of the sheet which is simultaneously released by the grippers of the drum 22.

In ihrer Funktion als Registertrommel sorgt die Trommel 23 dafür, dass eventuelle Abweichungen der Bogen­positionen vom exakten Register korrigiert werden. Ein derartiges System zur Registerkorrektur und seine Funktion sind in der genannten EP-B 0 136 972 beschrieben.In its function as a register drum, the drum 23 ensures that any deviations in the sheet positions from the exact register are corrected. Such a system for register correction and its function are described in the aforementioned EP-B 0 136 972.

Im Beispiel nach Figur 1 liegen alle Trommeln der Transportvorrichtung B sowie die Ueberführungstrommel 2 und die davor angeordneten Transporttrommeln 1 wenigstens näherungsweise waagerecht nebeneinander bzw. in einer horizontalen Ebene.In the example according to FIG. 1, all the drums of the transport device B and the transfer drum 2 and the transport drums 1 arranged in front of them are at least approximately horizontally next to one another or in a horizontal plane.

Das Stichtiefdruckwerk C besteht aus einem Druck­zylinder 25, auf den die Bogen von der Transporttrommel 24 gelangen, einem mit dem Druckzylinder 25 zusammen­wirkenden Plattenzylinder 26, der Stichdruckplatten trägt, vier Schablonenwalzen 27, die von Farbwerken 28 mit verschiedenen Farben eingefärbt werden und die Stichdruckplatten auf dem Plattenzylinder 26 einfärben, und aus einer Wischvorrichtung 30. Alle Farbwerke 28 sind in einem abfahrbaren Farbwerkgestell 29 installiert. Die im Stichdruckwerk C bedruckten Bogen werden anschliessend von einem Transportsystem 31, ins­besondere einem Kettengreifersystem, übernommen.The intaglio printing unit C consists of a printing cylinder 25, on which the sheets from the transport drum 24 arrive, a plate cylinder 26, which cooperates with the printing cylinder 25 and carries engraving printing plates, four stencil rollers 27, which are colored by inking units 28 with different colors, and the engraving printing plates on the Color plate cylinder 26 and from a wiper device 30. All inking units 28 are installed in a removable inking unit frame 29. The sheets printed in the engraving printing unit C are then taken over by a transport system 31, in particular a chain gripper system.

Mit der beschriebenen Druckmaschine können Banknoten auf beiden Seiten mit jeweils einem vierfarbigen Offsetdruck, der einen Sicherheitsuntergrund dar­stellt, und ausserdem auf einer ihrer Seiten, je nach Einstellung der Bogenwendevorrichtung, mit einem vier­farbigen Stahlstichdruck als Hauptmuster versehen werden. Gegebenenfalls kann auch die andere Bogenseite im Druckwerk A mit einem Hauptmuster versehen werden, wozu dann einer der Plattenzylinder dient, der in diesem Falle vorzugsweise mit einer ein Hauptmuster aufweisenden Tiefdruckplatte versehen ist, deren Ober­fläche ausserhalb der Vertiefungen vom entsprechenden Feuchtwerk angefeuchtet wird, damit sie bei der Ein­färbung der Druckplatte keine Farbe annimmt.With the printing machine described, banknotes can be provided on both sides with a four-color offset print, which represents a security background, and also on one of their sides, depending on the setting of the sheet turning device, with a four-color steel engraving print as the main pattern. If necessary, the other sheet side in the printing unit A can also be provided with a main pattern, for which purpose one of the plate cylinders is used, which in this case is preferably provided with a gravure printing plate having a main pattern, the surface of which outside the recesses is moistened by the corresponding dampening unit, so that it the color of the printing plate does not take on any color.

Die Druckmaschine nach Figur 2 unterscheidet sich von der nach Figur 1 dadurch, dass die Transporttrommeln 1 nach Figur 1 durch ein anderes bekanntes Bogenzufüh­rungssystem 33, beispielsweise durch Bogentransport­bänder, ersetzt sind. Am Ende dieses Bogentransport­systems 33 gelangen die Bogen über eine Stopptrommel 33a und eine Ueberführungstrommel 2 auf den Gummi­zylinder 3. Ein weiterer Unterschied zur Druckmaschine nach Figur 1 besteht darin, dass im oberen Farbwerk­gestell 14 des indirekt druckenden Druckwerks A nur ein Plattenzylinder 12 mit seinem Farbwerk, dafür jedoch im anderen Farbwerkgestell 17 drei Plattenzylinder 15 mit ihren Farbwerken installiert sind. Bei dieser Druck­maschine erstreckt sich der von einem Bogen durch­laufene Umfangsbereich des Gummizylinders 3 über einen Winkel von ungefähr 145°. Alle übrigen Bauteile des indirekt druckenden Druckwerks A, der Bogentransport­vorrichtung B und des Stichtiefdruckwerks C sind die gleichen wie beim Ausführungsbeispiel nach Figur 1.The printing machine according to FIG. 2 differs from that according to FIG. 1 in that the transport drums 1 according to FIG. 1 are replaced by another known sheet feed system 33, for example by sheet transport belts. At the end of this sheet transport system 33, the sheets reach the rubber cylinder 3 via a stop drum 33a and a transfer drum 2. Another difference from the printing machine according to FIG. 1 is that in the upper inking unit frame 14 of the indirectly printing printing unit A only one plate cylinder 12 with its inking unit, however, three plate cylinders 15 with their inking units are installed in the other inking unit frame 17. In this printing machine, the circumferential region of the blanket cylinder 3, through which an arc runs, extends over an angle of approximately 145 °. All other components of the indirectly printing printing unit A, the sheet transport device B and the intaglio printing unit C are the same as in the exemplary embodiment according to FIG. 1.

In der Druckmaschine gemäss dem Ausführungsbeispiel nach Figur 3 druckt die untere Hälfte des indirekt druckenden Druckwerks A nach dem Sammeldruckverfahren, auch Orlof-Verfahren genannt, während die obere Hälfte, wie im Beispiel nach den Figuren 1 und 2, nach dem Offsetdruckverfahren druckt. Das Bogenzuführungssystem 33 mit der Stopptrommel 33a, von der die Bogen auf die Ueberführungstrommel 2 gelangen, entspricht dem der Druckmaschine nach Figur 2. In der Bogen­transportvorrichtung B sind vor der Bogenwendetrommel 22 nur vier kleine Transporttrommeln vorgesehen, nämlich die Uebergabetrommel 18 und die folgenden drei Trommeln 20, wobei in Umfangsnähe aller vier kleinen Trommeln Trocknungsvorrichtungen 21 angeordnet sind.In the printing press according to the exemplary embodiment according to FIG. 3, the lower half of the indirectly printing printing unit A prints according to the collective printing process, also known as the Orlof process, while the upper half, as in the example according to FIGS. 1 and 2, prints according to the offset printing process. The sheet feed system 33 with the stop drum 33a, from which the sheets reach the transfer drum 2, corresponds to that of the printing machine according to FIG. 2. In the sheet transport device B, only four small transport drums are provided in front of the sheet turning drum 22, namely the transfer drum 18 and the following three drums 20, wherein drying devices 21 are arranged in the vicinity of all four small drums.

Die übrigen Teile der Bogentransportvorrichtung B und das Stichtiefdruckwerk C entsprechen den Ausführungs­beispielen nach den Figuren 1 und 2.The remaining parts of the sheet transport device B and the intaglio printing unit C correspond to the exemplary embodiments according to FIGS. 1 and 2.

Zur Ausführung eines Farbsammeldrucks auf einer Bogen­seite ist die untere Hälfte des indirekt druckenden Druckwerks A gemäss Figur 3 folgendermassen ausgebil­det:The lower half of the indirectly printing printing unit A according to FIG. 3 is designed as follows to carry out color collective printing on one sheet side:

Die beiden Gummizylinder 3 und 5 sind voneinander ab­gerückt. Der am Gummizylinder 5 anliegende Platten­zylinder 10 trägt eine ein vollständiges Druckmuster aufweisende Sammeldruckplatte. Zwischen diesem Platten­zylinder 10 und dem Gummizylinder 3 ist ein zusätzli­cher kleiner Zylinder in Form eines Bildübertragungs­zylinders 34 vorgesehen, der sowohl am Plattenzylinder 10 als auch am Gummizylinder 3 anliegt. Rechts der vertikalen Mittellinie des Gummizylinders 5 sind nach Figur 3 vier Plattenzylinder 7 angeordnet, welche Farbselektionsplatten tragen, die von Farbwerken 8 mit verschiedenen Farben eingefärbt werden. Ferner ist wiederum in jedem Farbwerk 8 ein Feuchtwerk 8′ vorgesehen, das bei Verwendung einer Nassoffset­druckplatte diese anfeuchtet.The two rubber cylinders 3 and 5 have moved away from each other. The plate cylinder 10 abutting the blanket cylinder 5 carries a complete printing plate having a complete printing pattern. Between this plate cylinder 10 and the rubber cylinder 3, an additional small cylinder in the form of an image transfer cylinder 34 is provided, which bears against both the plate cylinder 10 and the rubber cylinder 3. According to FIG. 3, four plate cylinders 7 are arranged to the right of the vertical center line of the rubber cylinder 5, which carry color selection plates, which are colored by inking units 8 with different colors. Furthermore, a dampening unit 8 'is again provided in each inking unit 8, which moistens it when using a wet offset printing plate.

Die Farbselektionsplatten haben ausgeschnittene Re­liefs, die jeweils eingefärbt werden und den in einer bestimmten Farbe zu druckenden Bereichen der Sammeldruckplatte entsprechen, und übertragen ein Mehrfarbenbild mit nebeneinanderliegenden Farben auf den als Farbsammelzylinder fungierenden Gummizylinder 5, der seinerseits die Sammeldruckplatte auf dem Plattenzylinder 10 einfärbt. Das Mehrfarbenbild dieser eingefärbten Sammeldruckplatte wird vermittels des Bildübertragungszylinders 34 auf den Bogen übertragen, der zwischen Gummizylinder 3 und Bildübertragungszylin­der 34 hindurchläuft. Die Sammeldruckplatte besteht vorzugsweise aus einer Hochdruckplatte, kann jedoch auch aus einer Nassoffset-Druckplatte bestehen, wobei in diesem Falle diese Druckplatte durch ein Feuchtwerk angefeuchtet wird, welches, in Drehrichtung des Plattenzylinders 10 gesehen, hinter der Berüh­rungsstelle mit dem Bildübertragungszylinder 34 und vor der Berührungsstelle mit dem Gummizylinder 5 angeordnet ist.The color selection plates have cut-out reliefs, each of which is colored and correspond to the areas of the collecting printing plate to be printed in a specific color, and transfer a multicolor image with adjacent colors to the rubber cylinder 5, which acts as an ink collecting cylinder, which in turn colors the collecting printing plate on the plate cylinder 10. The multicolor image of this colored collective printing plate is transferred to the sheet by means of the image transfer cylinder 34, which passes between the blanket cylinder 3 and the image transfer cylinder 34. The collecting printing plate preferably consists of a high-pressure plate, but can also consist of a wet offset printing plate, in which case this printing plate is moistened by a dampening system which, seen in the direction of rotation of the plate cylinder 10, behind the point of contact with the image transfer cylinder 34 and in front of the point of contact is arranged with the rubber cylinder 5.

Um den Bildübertragungszylinder 34 bequem am Umfang des Gummizylinders 3 unterzubringen, ist der Gummizylinder 5 relativ zum darüberliegenden Gummizylinder 3 etwas nach aussen, das heisst gemäss Figur 3 etwas nach rechts versetzt angeordnet. Dadurch ergibt sich am Um­fang des Gummizylinders 5, rechts von dessen vertikaler Mittellinie, Platz zur Installation von vier Farbselek­tionsplatten tragenden Plattenzylindern 7, so dass der Gummizylinder 5 bei diesem Ausführungsbeispiel mit insgesamt fünf Plattenzylindern zusammenarbeitet.In order to accommodate the image transfer cylinder 34 comfortably on the circumference of the rubber cylinder 3, the rubber cylinder 5 is arranged somewhat outwards relative to the rubber cylinder 3 lying above it, that is to say offset slightly to the right according to FIG. This results in space on the circumference of the rubber cylinder 5, to the right of its vertical center line, for the installation of four plate cylinders 7 carrying four color selection plates, so that the rubber cylinder 5 cooperates with a total of five plate cylinders in this exemplary embodiment.

Auf Grund dieser Konfiguration ist die Bogenzuführung zum Gummizylinder 3 gegenüber den Druckmaschinen nach den Figuren 1 und 2 etwas nach oben versetzt und daher der von einem Bogen durchlaufene Umfangsbereich des Gummizylinders 3 zwischen Ueberführungstrommel 2 und Uebergabetrommel 18 etwas grösser; er ist im be­trachteten Beispiel gleich dem halben Zylinderumfang, könnte gegebenenfalls jedoch ohne weiteres auch etwas kleiner gemacht werden. Im oberen freien Umfangsbereich des Gummizylinders 3 sind drei Plattenzylinder, nämlich rechts der vertikalen Mittellinie ein Plattenzylinder 12 mit seinem Farbwerk 13 im Farbwerkgestell 14 und links der vertikalen Mittelinie zwei Plattenzylinder 15 mit ihren Farbwerken 16 im Farbwerkgestell 17, vorge­sehen.Because of this configuration, the sheet feed to the blanket cylinder 3 is offset somewhat upwards compared to the printing presses according to FIGS. 1 and 2, and therefore the circumferential area of the blanket cylinder 3 between the transfer drum 2 and the transfer drum 18, which is traversed by an arc, is somewhat larger; in the example considered, it is equal to half the cylinder circumference, but could also be made somewhat smaller if necessary. In the upper free peripheral area of the blanket cylinder 3 are three plate cylinders, namely a plate cylinder 12 with its inking unit 13 in the inking unit frame 14 to the right of the vertical center line and two plate cylinders 15 to the left of the vertical center line with their inking units 16 in the inking unit frame 17.

Die Bogen erhalten also beim Durchlaufen des Druck­spalts zwischen Gummizylinder 3 und Bildübertragungs­zylinder 34 auf ihrer einen Seite einen Dreifarben-­Offsetdruck und auf ihrer anderen Seite einen Vierfarben-Sammeldruck. Es lassen sich also auf diese Weise auf beiden Banknotenseiten Sicherheitsuntergründe nach unterschiedlichen Druckverfahren herstellen, wobei das Offsetdruckverfahren Bilder mit überlagerten Farben und das Sammeldruckverfahren Bilder mit neben­einanderliegenden Farben liefert.The sheets are thus given a three-color offset print on one side and a four-color collective print on their other side as they pass through the printing gap between the blanket cylinder 3 and the image transfer cylinder 34. In this way, it is possible in this way to produce security substrates on both sides of the banknote using different printing methods, the offset printing method providing images with superimposed colors and the collective printing method providing images with adjacent colors.

Die Figuren 4 bis 6 zeigen ein weiteres Ausführungs­beispiel einer Druckmaschine, in welcher das indirekt druckende Druckwerk A konvertierbar ist und drei ver­schiedene Druckstellungen einnehmen kann. Die Druck­maschine nach den Figuren 4 bis 6 hat die gleiche Bogentransportvorrichtung B, das gleiche Stichtief­druckwerk C und ein im wesentlichen gleich aufgebautes Druckwerk A wie die bereits beschriebene Druckmaschine nach Figur 3. Gleiche Teile sind mit denselben Bezugs­zeichen bezeichnet.FIGS. 4 to 6 show a further exemplary embodiment of a printing press in which the indirectly printing printing unit A can be converted and can have three different printing positions. The printing machine according to FIGS. 4 to 6 has the same sheet transport device B, the same intaglio printing unit C and an essentially identical printing unit A as the printing machine according to FIG. 3 which has already been described. The same parts are identified by the same reference numerals.

Die Unterschiede bestehen darin, dass der Gummizylinder 5 zwischen einer Offsetdruckstellung (Figuren 5 und 6) und einer Sammeldruckstellung (Figur 4) verstellbar ist, dass der Bildübertragungszylinder 34 zwischen einer Arbeitsstellung, in der er sowohl am Gummi­zylinder 3 als auch am Plattenzylinder 10 anliegt, und einer von diesen beiden Zylindern abgerückten Ausser­betriebsstellung verstellbar ist, dass der Plattenzylinder 10 ebenfalls verstellbar ist, ein zugeordnetes Farbwerk 11 hat und entweder eine Offsetdruckplatte (Figuren 5 und 6) oder eine Sammeldruckplatte (Figur 4) trägt und dass schliesslich die den Gummizylinder 5 berührenden Plattenzylinder 7 entweder Offsetdruckplatten (Figuren 5 und 6) oder Farbselektionsplatten (Figur 4) tragen.The differences are that the rubber cylinder 5 is adjustable between an offset printing position (FIGS. 5 and 6) and a collective printing position (FIG. 4), that the image transfer cylinder 34 is between a working position in which it rests against both the rubber cylinder 3 and the plate cylinder 10. and an out-of-operation position moved away from these two cylinders is adjustable, that the plate cylinder 10 is also adjustable, has an assigned inking unit 11 and either one Offset printing plate (Figures 5 and 6) or a collective printing plate (Figure 4) and that finally the plate cylinder 7 touching the blanket cylinder 5 either carry offset printing plates (Figures 5 and 6) or color selection plates (Figure 4).

Das Bogenzuführungssystem 33 mit der Stopptrommel 33a ist das gleiche wie bei der Druckmaschine nach Figur 3. Dem Gummizylinder 5 sind ausser dem Plattenzylinder 10 mit seinem Farbwerk 11 wiederum vier Plattenzylinder 7 mit ihren Farbwerken 8 zugeordnet, die rechts der vertikalen Mittellinie des Gummizylinders 5 liegen. Der Gummizylinder 3 wird wiederum, wie bei der Druck­maschine nach Figur 3, von drei Offsetplatten tragenden Plattenzylindern 12 und 15 eingefärbt.The sheet feed system 33 with the stop drum 33a is the same as in the printing machine according to FIG. 3. In addition to the plate cylinder 10 with its inking unit 11, the blanket cylinder 5 is in turn associated with four plate cylinders 7 with their inking units 8, which are to the right of the vertical center line of the blanket cylinder 5. The rubber cylinder 3 is in turn, as in the printing machine according to Figure 3, colored by three offset plate plate cylinders 12 and 15.

In der Sammeldruckstellung nach Figur 4 ist der Gummi­zylinder 5 vom Gummizylinder 3 abgerückt; der Platten­zylinder 10 trägt die ein vollständiges Druckmuster aufweisende Sammeldruckplatte, liegt am Gummizylinder 5 an und ist von dem ihm zugeordneten Farbwerk 11 getrennt, was beispielsweise einfach durch Abstellung der benachbarten Farbwalzen bzw. Uebertragungswalzen erfolgen kann. Der Bildübertragungszylinder 34 nimmt seine Arbeitsstellung ein. Die vier Plattenzylinder 7 tragen Farbselektionsplatten. Die Sammeldruckstellung nach Figur 4 und das erzeugte Sammeldruckbild entsprechen genau der Konfiguration der beschriebenen Druckmaschine nach Figur 3 und dem dort erhaltenen Sammeldruckbild.4, the rubber cylinder 5 has moved away from the rubber cylinder 3; the plate cylinder 10 bears the complete printing plate having a complete printing pattern, rests on the blanket cylinder 5 and is separated from the inking unit 11 assigned to it, which can be done, for example, simply by switching off the adjacent inking rollers or transfer rollers. The image transfer cylinder 34 assumes its working position. The four plate cylinders 7 carry color selection plates. The collective print position according to FIG. 4 and the collective print image generated correspond exactly to the configuration of the described printing press according to FIG. 3 and the collective print image obtained there.

In der Offsetdruckstellung nach Figur 5 ist der Gummi­zylinder 5, wie im Falle der Druckmaschine nach Figur 1, gegen den Gummizylinder 3 gedrückt; der Platten­zylinder 10 trägt eine vom angestellten Farbwerk 11 eingefärbte Offsetdruckplatte, liegt am Gummizylinder 5 an und färbt diesen ein. Die Plattenzylinder 7 sind ebenfalls mit Offsetdruckplatten versehen. Der Bild­übertragungszylinder 34 nimmt seine Ausserbetriebs­stellung ein, in weicher er sowohl vom Plattenzylinder 10 als auch vom Gummizylinder 3 abgerückt ist. In diesem Falle wird der den Druckspalt zwischen den Druckzylindern 3 und 5 passierende Bogen auf seiner oberen Seite mit einem Dreifarben-Offsetdruck und auf seiner unteren Seite mit einem Fünffarben-Offsetdruck versehen.In the offset printing position according to FIG. 5, the rubber cylinder 5 is pressed against the rubber cylinder 3, as in the case of the printing machine according to FIG. 1; the plate cylinder 10 carries one of the employed inking unit 11 inked offset printing plate, lies against the rubber cylinder 5 and dyes this. The plate cylinders 7 are also provided with offset printing plates. The image transfer cylinder 34 assumes its inoperative position, in which it has moved away from both the plate cylinder 10 and the blanket cylinder 3. In this case, the sheet passing the printing nip between the printing cylinders 3 and 5 is provided with a three-color offset print on its upper side and with a five-color offset print on its lower side.

Figur 6 zeigt eine weitere Offsetdruckstellung des Druckwerks A, in welcher die Gummizylinder 3 und 5 wiederum gegeneinandergepresst sind, der Plattenzylin­der 10 jedoch vom Gummizylinder 5 abgerückt ist und mit dem seine Arbeitsstellung einnehmenden Bildüber­tragungszylinder 34 zusammenwirkt, der gegen den Gummizylinder 3 gedrückt ist. Der Plattenzylinder 10 trägt eine vom angestellten Farbwerk 11 eingefärbte Offsetdruckplatte, deren Bild mittels des Bildübertragungszylinders 34 auf den Bogen übertragen wird. Die vier Plattenzylinder 7 tragen den Gummi­zylinder 5 einfärbende Offsetdruckplatten. Auf diese Weise erhält ein Bogen zunächst im Druckspalt zwischen den Gummizylindern 3 und 5 auf seiner oberen Seite einen Dreifarben-Offsetdruck und auf seiner unteren Seite einen Vierfarben-Offsetdruck und anschliessend auf seiner unteren Seite durch den Bild­übertragungszylinder 34 einen weiteren Einfarben­offsetdruck.FIG. 6 shows a further offset printing position of the printing unit A, in which the rubber cylinders 3 and 5 are in turn pressed against one another, but the plate cylinder 10 has moved away from the rubber cylinder 5 and interacts with the image transfer cylinder 34 which assumes its working position and which is pressed against the rubber cylinder 3. The plate cylinder 10 carries an offset printing plate colored by the employed inking unit 11, the image of which is transferred to the sheet by means of the image transfer cylinder 34. The four plate cylinders 7 carry the offset printing plates which color the blanket 5. In this way, a sheet first receives a three-color offset print in the printing nip between the rubber cylinders 3 and 5 on its upper side and a four-color offset print on its lower side, and then a further single-color offset print on its lower side through the image transfer cylinder 34.

Die Erfindung ist nicht auf die beschriebenen Ausfüh­rungsbeispiele beschränkt, sondern lässt insbesondere hinsichtlich der Anzahl und genauen Anordnung der mit den Gummizylindern 3 und 5 zusammenwirkenden Platten­zylinder, des Aufbaus der aus Trommeln zusammenge­setzten Bogentransportvorrichtung sowie des Aufbaus des Stichtiefdruckwerks manigfache Varianten zu.The invention is not limited to the exemplary embodiments described, but rather allows for the number and exact arrangement of the the blanket cylinders 3 and 5 interacting plate cylinders, the construction of the sheet transport device composed of drums and the construction of the intaglio printing unit.
