Zunächst wird auf Fig. 1 und 2 Bezug genommen. Eine im Übrigen nicht näher dargestellte Flexodruckmaschine umfasst mehrere, beispielsweise zwei nebeneinander angeordnete Drucktürme 01, von denen ein jeder mehrere, insbesondere zwei übereinander angeordnete Druckeinheit 03, insbesondere Satellitendruckeinheiten 03 umfasst, durch die hindurch Bedruckstoffbahnen 02, insbesondere Papierbahnen 02 zum zweiseitigen, mehrfarbigen Bedrucken geführt sind. Die Drucktürme 01 können auf einem nicht dargestellten Maschinenpodest angeordnet sein und unterhalb des Podests können nicht dargestellte Rollenwechsler angeordnet sein, die die Drucktürme 01 mit den Papierbahnen 02 speisen. Die Drucktürme 01 werden von den Papierbahnen 02 in Transportrichtung von unten nach oben durchlaufen. Bedruckte, aus den Drucktürmen 01 herausgeführte Papierbahnen 02 können in einem nicht dargestellten Oberbau der Druckmaschine zusammengeführt und einer oder mehreren Bearbeitungsstationen wie beispielsweise einer Schneidstation sowie einer oder mehreren Nachbearbeitungsstationen wie beispielsweise einem Falzwerk zugeführt werden.First, reference is made to FIGS. 1 and 2. An otherwise not shown flexographic printing machine comprises several, for example, two juxtaposed printing towers 01, each of which several, especially two superimposed printing unit 03, in particular satellite printing units 03, through which printed material webs 02, in particular paper webs 02 for two-sided, multi-color printing are. The printing towers 01 can be arranged on a machine platform, not shown, and underneath the pedestal can be arranged roll changers, not shown, which feed the printing towers 01 with the paper webs 02. The printing towers 01 are traversed by the paper webs 02 in the transport direction from bottom to top. Printed, led out of the towers 01 paper webs 02 can be merged in a superstructure of the printing machine, not shown, and one or more processing stations such as a cutting station and one or more post-processing stations such as a folding unit supplied.

Jede Satellitendruckeinheit 03 umfasst einen als Gegendruckzylinder 05 dienenden zentralen Zylinder 05, nämlich den Satellitenzylinder 05, sowie mehrere, vorzugsweise mindestens vier, im Falle des Ausführungsbeispiels genau vier am Satellitenzylinder 05 angeordnete Druckwerke 04. Jedes Druckwerk 04 ist für den Hochdruck ausgebildet, insbesondere für den Flexodruck. Der allgemeine Aufbau und die Funktionsweise von Flexodruckwerken 04 ist allgemeiner Stand der Technik, so dass hierauf nicht mehr im Detail eingegangen werden muss. In der stark schematisierten Darstellung gemäß Fig. 1 und 2 sind der Übersichtlichkeit halber daher jeweils nur die beiden Zylinder 06; 07, nämlich der am Satellitenzylinder 05 anliegende und mit diesem einen Druckspalt bildende Formzylinder 06 und die am Formzylinder 06 anliegende Rasterwalze 07 (Bauteil 07), sowie ein die Rasterwalze 07 mit Druckfarbe speisendes Bauteil 08, z. B. Kammerrakel 08, schematisch skizziert.Each satellite printing unit 03 comprises a counter-pressure cylinder 05 serving central cylinder 05, namely the satellite cylinder 05, and a plurality, preferably at least four, in the case of the embodiment exactly four arranged on the satellite cylinder 05 printing units 04. Each printing unit 04 is designed for high pressure, especially for flexographic printing. The general structure and operation of flexographic printing units 04 is generally state of the art, so that it need not be discussed in detail. In the highly schematic representation according to FIGS. 1 and 2, for the sake of clarity, only the two cylinders 06; 07, namely the voltage applied to the satellite cylinder 05 and with this a pressure nip forming cylinder 06 and the cylinder 06 resting on the anilox roller 07 (component 07), and an anilox roller 07 with ink-feeding component 08, z. B. chambered doctor blade 08, schematically outlined.

Die Ausführungsform nach Fig. 2 unterscheidet sich von der Ausführungsform nach Fig. 1 im Wesentlichen lediglich durch die jeweils etwas unterschiedliche Anordnung der Druckwerke 04 am Satellitenzylinder 05.The embodiment according to FIG. 2 differs from the embodiment according to FIG. 1 essentially only by the respectively somewhat different arrangement of the printing units 04 on the satellite cylinder 05.

Die Flexodruckmaschine ist beispielsweise für den Zeitungsdruck ausgebildet. Die Breite der Maschine ist, in axialer Richtung der Zylinder 05; 06; 07 gesehen, derart, dass die Formzylinder 06 in axialer Richtung als Druckbild mindestens zwei, vorzugsweise vier Zeitungsseiten aufweisen. Der Durchmesser der Formzylinder 06 ist vorzugsweise so gewählt, dass die Formzylinder 06 in Umfangsrichtung als Druckbild vier Zeitungsseiten aufweisen. Insbesondere kann der Ballen des Formzylinders 06 einen Umfang von 1.100 mm bis 1.300 mm und eine Länge von 1.400 mm bis 1.800 mm aufweisen.The flexographic printing machine is designed, for example, for newspaper printing. The width of the machine is, in the axial direction of the cylinder 05; 06; 07, such that the forme cylinder 06 in the axial direction as a printed image at least two, preferably four newspaper pages. The diameter of the forme cylinder 06 is preferably selected so that the forme cylinder 06 has four newspaper pages in the circumferential direction as a printed image. In particular, the bale of the forme cylinder 06 can have a circumference of 1,100 mm to 1,300 mm and a length of 1,400 mm to 1,800 mm.

Vorzugsweise tragen die Formzylinder 06 in axialer Richtung vier (hier nicht dargestellte) Flexodruckplatten nebeneinander und in Umfangsrichtung zwei Flexodruckplatten hintereinander. Vorzugsweise trägt jede der Druckplatten als Druckbild genau eine stehende Zeitungsseite oder zwei liegende Zeitungsseiten.Preferably, the forme cylinders 06 bear four flexographic printing plates side by side in the axial direction (not shown here) and two flexographic printing plates in succession in the circumferential direction. Preferably, each of the printing plates bears as a printed image exactly one newspaper page standing or two lying newspaper pages.

Der Durchmesser des Satellitenzylinders 05 ist vorzugsweise ein ganzzahliges Vielfaches, insbesondere ein Dreifaches des Durchmessers der zugeordneten Formzylinder 06; es kann jedoch auch vorteilhaft sein, den Satellitenzylinder 05 so zu dimensionieren, dass sein Durchmesser insbesondere ein 2,5-faches des Durchmessers der zugeordneten Formzylinder 06 beträgt. Gemäß einem weiteren Aspekt ist es vorteilhaft, den Umfang des Satellitenzylinders 05 so zu dimensionieren, dass er einem ganzzahligen Vielfachen der Abschnittlänge eines mit der Flexodruckmaschine gefertigten Druckprodukts entspricht.The diameter of the satellite cylinder 05 is preferably an integer multiple, in particular a triple of the diameter of the associated forme cylinder 06; However, it may also be advantageous to dimension the satellite cylinder 05 so that its diameter is in particular a 2.5 times the diameter of the associated forme cylinder 06. According to a further aspect, it is advantageous to dimension the circumference of the satellite cylinder 05 so that it corresponds to an integer multiple of the section length of a printed product manufactured with the flexographic printing press.

Der Formzylinder 06, die Rasterwalze 07 und die Kammerrakel 08 eines jeden Druckwerks 04 sind jeweils so geführt, dass sie an den Satellitenzylinder 05 anstellbar und von diesem abstellbar sind. Hierzu sind die Formzylinder 06, die Rasterwalzen 07 und die Kammerrakeln 08 jeweils in Lagereinheiten 14 gelagert, vgl. Fig. 2, die, zusätzlich zu einer rotatorischen Lagerung, jeweils auch eine Linearlagerung 15 umfassen. Vorzugsweise ist jedem Formzylinder 06, jeder Rasterwalze 07 und jeder Kammerrakel 08 jeweils eine eigene Linearlagerung 15 zugeordnet. Die Lagereinheiten 14 bzw. Linearlagerungen 15 der Formzylinder 06 und der Rasterwalzen 07 einerseits und der Kammerrakeln 08 andererseits können konstruktiv im Einzelnen jeweils unterschiedlich ausgebildet sein.The forme cylinder 06, the anilox roller 07 and the chamber doctor blade 08 of each printing unit 04 are each guided so that they can be adjusted to the satellite cylinder 05 and offset from this. For this purpose, the forme cylinder 06, the anilox rollers 07 and the chamber doctor blades 08 are each mounted in bearing units 14, cf. Fig. 2, in addition to a rotary bearing, each also comprise a linear bearing 15. Preferably, each forme cylinder 06, each anilox roller 07 and each chambered doctor blade 08 each have its own linear bearing 15 assigned. The bearing units 14 or linear bearings 15 of the forme cylinder 06 and the anilox rollers 07 on the one hand and the chambered doctor blades 08 on the other hand can be structurally designed in each case differently.

Weiterhin sind vorzugsweise alle Zylinder 05; 06; 07, also insbesondere der Satellitenzylinder 05, die Formzylinder 06 und die Rasterwalzen 07 von jeweils eigenen, in Fig. 1 und 2 nicht dargestellten Antriebsmotoren angetrieben, bei denen es sich insbesondere jeweils um winkellagegeregelte Elektromotoren, vorzugsweise um einen Synchronmotor und/oder einen Antriebsmotor mit Permanentmagneterregung handeln kann.Furthermore, preferably all cylinders 05; 06; 07, ie in particular the satellite cylinder 05, the forme cylinder 06 and the anilox rollers 07 each driven by their own, not shown in Fig. 1 and 2 drive motors, which in particular each angular position controlled electric motors, preferably a synchronous motor and / or a drive motor with Permanent magnet excitation can act.

Gemäß einem vorteilhaften Aspekt der Erfindung, der im Folgenden im Zusammenhang mit Fig. 3 und 4 erläutert wird, wird die Möglichkeit geschaffen, mit einfachen Mitteln das Bedrucken von unterschiedlichen Papierbahnbreiten zu ermöglichen.According to an advantageous aspect of the invention, which will be explained in the following in connection with FIGS. 3 and 4, the possibility is created by simple means that To print on different web widths.

Fig. 3 zeigt schematisch die Anordnung von formzylinderseitigen Registerelementen 51; 52; 53; 54, insbesondere Registeranschlägen 51; 52; 53; 54 in den Verschlüssen eines (hier nicht dargestellten) Formzylinders 06 mit vier Druckplatten 56 bzw. 56A; 56B; 56C; 56D in der Breite zum Bedrucken einer (hier nicht dargestellten) Bedruckstoffbahn 02 bzw. Papierbahn 02 einer vorgegebenen (maximalen) Breite b. In der Regel werden die mit entsprechenden druckplattenseitigen Registerelementen 57 wie insbesondere Ausstanzungen 57 zusammenwirkenden bzw. in Eingriff stehenden Registeranschläge 51; 52; 53; 54 in den Verschlüssen wie in Fig. 3 dargestellt so platziert, dass das Abstandsmaß zwischen den einzelnen Registeranschlägen 51; 52; 53; 54 immer gleich ist. Mit einer solchen Anordnung ist es auch möglich, schmälere Papierbahnen 02 mit vier Seiten in der Breite zu bedrucken, wenn entweder das Druckbild auf den Druckplatten 56A; 56B; 56C; 56D relativ zur Plattenmitte in der Breite versetzt wird oder aber durch den Einsatz von Panoramaplatten.Fig. 3 shows schematically the arrangement of form cylinder side register elements 51; 52; 53; 54, in particular register stops 51; 52; 53; 54 in the closures of a (not shown here) forme cylinder 06 with four pressure plates 56 and 56A; 56B; 56C; 56D in width for printing a (not shown here) printing substrate 02 or paper web 02 a predetermined (maximum) width b. In general, the corresponding with pressure plate side register elements 57 such as punching in particular 57 cooperating or engaged register stops 51; 52; 53; 54 is placed in the closures as shown in FIG. 3 such that the distance between the individual register stops 51; 52; 53; 54 is always the same. With such an arrangement, it is also possible to print narrower paper webs 02 having four sides in width when either the print image on the printing plates 56A; 56B; 56C; 56D relative to the center of the plate is offset in width or by the use of panoramic panels.

Nachteilig ist im ersten Fall, dass die Verschmälerung der Papierbahn 02 nur in einem sehr kleinen und zum wirtschaftlichen Nutzen in keinem Verhältnis stehenden Rahmen erfolgen kann, da in der Regel der seitlich nicht druckende Bereich bereits entsprechend optimiert wurde und zudem in der Druckvorstufe die Lage des Druckbildes zur Mittellinie der Druckplatte 56 bzw. 56A; 56B; 56C; 56D in Abhängigkeit von der endgültigen Lage der Druckplatte 56 bzw. 56A; 56B; 56C; 56D in der Maschine festgelegt werden muss, was vor allem bei großen Maschinenanlagen eine logistische Meisterleistung voraussetzt.A disadvantage in the first case that the narrowing of the paper web 02 can be done only in a very small and unprofitable frame for economic benefit, since usually the laterally non-printing area has already been optimized accordingly and also in the prepress stage, the location of the Printed image to the center line of the printing plate 56 or 56A; 56B; 56C; 56D depending on the final position of the pressure plate 56 or 56A; 56B; 56C; 56D must be set in the machine, which requires a logistical masterpiece, especially in large machinery.

Nachteilig ist im zweiten Fall, dass in der Druckvorstufe Panoramaplatten verarbeitet werden müssen, was in der Regel einen zusätzlichen Aufwand durch die Beschaffung separater Belichtereinrichtungen und Plattenbearbeitungsstraßen und deren Bereithaltung und Wartung bedingt. Negativ wirkt sich auch aus, dass bei einem teilweisen Aktualisierungswechsel der Zeitungsseiten auch nicht betroffene Zeitungsseiten gewechselt werden müssen, da sie auf der gleichen Panoramaplatte liegen wie die zu wechselnden Zeitungsseiten. Vorteilhaft ist andererseits, dass eine große Bandbreite an verschiedenen Papierbahnbreiten stufenlos zu realisieren ist. In der Praxis allerdings sind die zu bedruckenden Papierbahnbreiten fixiert, um auch die Papierlogistik sowie die der Druckmaschine nachgeordneten Transport- und Versandeinrichtungen nicht unnötig zu komplizieren.A disadvantage in the second case, that in the prepress panoramic slabs must be processed, which usually requires additional effort by the procurement of separate imagesetter and plate processing lines and their availability and maintenance. It also has a negative effect that newspaper pages that have not been affected have a partial change of newspaper pages must be changed because they are on the same panorama plate as the newspaper pages to be changed. On the other hand, it is advantageous that a wide range of different paper web widths can be realized steplessly. In practice, however, the paper web widths to be printed are fixed in order not to complicate the paper logistics as well as the transport and shipping facilities downstream of the printing machine.

Um diese Nachteile zu vermeiden und mit einfachen Mitteln das Bedrucken von zumindest drei unterschiedlichen Papierbahnbreiten realisieren zu können (wobei die maximale Verschmälerung abhängig ist von den konstruktiven Gegebenheiten der Verschlüsse und die Verschmälerung in Stufen gleicher Größe erfolgt und die Verschmälerung nicht nur Teilbahnen der größten Papierbahnbreite b beinhaltet), werden erfindungsgemäß die Registeranschläge 52; 53 der näher zur Maschinenlängsachse L angeordneten Druckplatten 56B; 56C um ein Maß zur Maschinenmitte hin versetzt, das um die Hälfte kleiner ist als das Maß a, das die geringste Papierbahnverschmälerung charakterisiert, vgl. Fig. 4.In order to avoid these disadvantages and to be able to realize the printing of at least three different paper web widths with simple means (the maximum narrowing depends on the structural conditions of the closures and the narrowing is done in stages of the same size and the narrowing not only partial webs of the largest paper web width b includes), according to the invention, the register stops 52; 53 arranged closer to the machine longitudinal axis L printing plates 56B; 56C is offset by one half of the machine center, which is smaller by half than the dimension a, which characterizes the lowest paper web narrowing, cf. Fig. 4.

Um mit dieser Konfiguration der Registeranschläge 51; 52; 53; 54 verschiedene Papierbahnbreiten bedrucken zu können, ist zusätzlich eine unterschiedliche Ausstanzung 57 (57.1; 57.2; 57.3) der Druckplatten 56 notwendig, deren Breite ebenfalls der Verschmälerung der Papierbahn 02 angepasst wird, wobei die Plattenbreite jeweils um ein Viertel des Maßes a reduziert wird. In der Druckvorstufe sind die schmäleren Druckplatten 56 mit den vorhandenen Plattenstraßen und Belichtungseinrichtungen mit gleichem Anschlagsystem verarbeitbar. Im Folgenden werden die Druckplatten 56 in ihrer ursprünglichen, maximalen Breite mit 56.1, in ihrer demgegenüber jeweils um den Betrag a/4 verringerten Breite mit 56.2 und in ihrer gegenüber der ursprünglichen Breite jeweils um den Betrag a/2 verringerten Breite mit 56.3 bezeichnet.In order with this configuration of register stops 51; 52; 53; To be able to print 54 different paper web widths, a different punching 57 (57.1, 57.2, 57.3) of the printing plates 56 is additionally necessary, the width of which is also adapted to the narrowing of the paper web 02, whereby the plate width is reduced by one quarter of the dimension a. In the pre-press, the narrower printing plates 56 can be processed with the existing plate lines and exposure devices with the same stop system. In the following, the printing plates 56 are denoted by 56.1 in their original, maximum width, 56.2 in their respective reduced width by the amount a / 4, and 56.3 in their width reduced by the amount a / 2 compared to the original width.

Bei der Produktion mit der größten Papierbahnbreite b müssen deshalb die Druckplatten 56.1 mit drei Ausstanzungen 57.1 symmetrisch zur Mitte der Druckplatte 56 versehen werden, deren Mittelabstand zueinander um das Maß a versetzt ist.For production with the largest paper web width b, therefore, the printing plates must 56.1 are provided with three punched 57.1 symmetrical to the center of the pressure plate 56, the center distance is offset from one another by the amount of a.

Bei der Produktion mit einer Papierbahn 02, die um das Maß a verschmälert wird, werden die Druckplatten 56.2, deren Breite jeweils um a/4 verringert wurde, mit zwei Ausstanzungen 57.2 symmetrisch zur Mitte der Druckplatte 56.2 versehen, wobei deren Mittelabstand zueinander um 3/4 des Maßes a versetzt ist.In the production with a paper web 02, which is narrowed by the dimension a, the pressure plates 56.2, whose width was reduced by a / 4, provided with two punched 57.2 symmetrically to the center of the pressure plate 56.2, wherein the center distance to each other by 3 / 4 of the measure a is offset.

Bei der Produktion mit einer Papierbahn 02, die um das doppelte Maß a verschmälert wird, werden die Druckplatten 56.3, deren Breite jeweils um a/2 verringert wurde, mit vier Ausstanzungen 57.3 symmetrisch zur Mitte der Druckplatte 56.3 versehen, wobei deren Mittelabstand zueinander um die Hälfte des Maßes a versetzt ist.In the production with a paper web 02, which is narrowed by twice the amount a, the printing plates 56.3, whose width was reduced by a / 2, provided with four punched 57.3 symmetrical to the center of the pressure plate 56.3, wherein the center distance to each other to the Half of the measure a is offset.

Die wesentlichen Vorteile des Verfahrens sind, dass auf allen Druckplatten 56 das Druckbild relativ zur Plattenmitte gleich platziert ist und somit in der Druckvorstufe keine Rücksicht auf die endgültige Lage der Druckplatte 56 in der Maschine genommen werden muss, dass der Plattenverbrauch durch die Verwendung schmälerer Druckplatten 56.2; 56.3 minimiert wird, dass die vorhandenen Belichtungssysteme und Plattenstraßen weiterhin verwendet werden können, und dass die direkt hintereinander erfolgenden Produktionen mit unterschiedlichen Papierbahnbreiten ohne zusätzliche Umrüstarbeiten in Kombination mit motorisch verschiebbaren Trichtern erfolgen können.The main advantages of the method are that on all printing plates 56, the printed image is placed the same relative to the plate center and thus no consideration must be taken in the prepress stage on the final position of the pressure plate 56 in the machine that the plate consumption by the use of narrower pressure plates 56.2 ; 56.3 is minimized, that the existing exposure systems and slabs can continue to be used, and that the direct succession of productions with different paper web widths can be done without additional retooling in combination with motorized hoppers.
