Zwischen Zylinder und Gummituch kann auch zu diesem Zweck eine Unterlage angeordnet sein, die nicht über die gesamte Länge des Gummituches in Umfangsrichtung weist und eine Unterbrechung aufweist. Zur Aufnahme der unterbrochenen Untedage ist neben dem Spannkanal für das Gummituch ein Einsteckschlitz auf dem Umfang des Zylinders vorgesehen. Die in Längsrichtung des Übertragungszylinders angeordneten Ausnehmungen und der das Gummituch aufnehmende Kanal werden so angeordnet, dass sie im Berührungsbereich jeweils mit dem Kanal des Plattenzylinders zusammen wirken.In DE 34 41 175 C2 are for the purpose of relaxation of the blanket Recesses proposed in the cylinder surface of the transfer cylinder. Between cylinder and blanket can also for this purpose a pad be arranged, not over the entire length of the blanket in the circumferential direction points and has an interruption. To record the interrupted Untedage is next to the clamping channel for the blanket, a slot on the circumference of the Cylinder provided. The arranged in the longitudinal direction of the transfer cylinder Recesses and the rubber cloth receiving channel are arranged so that in the contact area in each case with the channel of the plate cylinder together Act.

Die DE 197 40 575 A1 zeigt zusammen wirkende Form- und Übertragungszylinder, wobei in einem Ausführungsbeispiel die Übertragungszylinder in Umfangsrichtung hintereinander zwei Spannkanäle und zwei in den Spannkanälen gehaltene Gummitücher aufweisen. Ein doppelt großer Übertragungszylinder wirkt in einem anderen Beispiel mit einem doppelt großen Formzylinder zusammen, wobei jedoch beide Zylinder in Umfangsrichtung nur einen Spannkanal aufweisen. In allen Beispielen rollen die Kanäle nicht aufeinander ab.DE 197 40 575 A1 shows cooperating forming and transfer cylinders, wherein in one embodiment, the transfer cylinders in the circumferential direction two clamping channels and two rubber blankets held in the clamping channels exhibit. A double-sized transfer cylinder acts in another example a double-sized form cylinder together, but both cylinders in Have circumferential direction only one clamping channel. In all examples, the channels are rolling not off each other.

Durch die DE-OS 19 60 635 ist ein einzelner Formzylinder offenbart, welcher auf seinem Umfang in Umfangsrichtung mehrere Kanäle zur Befestigung von Druckformen aufweist. Bei Belegung des Formzylinders mit einer Druckform in Umfangsrichtung, kann zumindest einer der Kanäle überdeckt sein.From DE-OS 19 60 635 a single form cylinder is disclosed which on his Circumference in the circumferential direction has several channels for the attachment of printing plates.

Die Anordnung jeweils mehrerer in Längsrichtung des Form- und/oder Übertragungszylinders verlaufender Kanäle wird den verschiedensten Anforderungen je nach Bedarf gerecht, ohne den Zylinder bei wechselnden Anforderungen an bestehende Druckmaschinen austauschen zu müssen bzw. in der Fertigung jedes Anforderungsprofil einzeln zu berücksichtigen.The arrangement in each case a plurality in the longitudinal direction of the forming and / or Transfer cylinder extending channels will meet a variety of requirements depending as required, without the cylinder with changing requirements to existing To have to exchange printing machines or in the production of each requirement profile to be considered individually.

Vorteilhaft ist insbesondere, dass sowohl verschiedene Formate der Aufzüge, in Umfangs- und Längsrichtung der Zylinder, als auch verschiedene Konstellationen und Phasenverschiebungen der wechselseitig miteinander zusammen wirkenden Zylinder berücksichtigbar, und dadurch hinsichtlich der z.T. konkurrierenden Anforderungen an Registerhaltigkeit, Vibrationsarmut, Anordnung der aneinander abrollenden Druckbereiche und Minimierung des nicht bedruckbaren Papiers bedarfsweise optimierbar sind.In particular, it is advantageous that both different formats of elevators, in Perimeter and longitudinal direction of the cylinder, as well as different constellations and Phase shifts of mutually interacting cylinders considered, and thereby z.T. competing requirements Register stability, low vibration, arrangement of the rolling pressure ranges and minimizing the non-printable paper can be optimized as needed.

Durch die Anordnung mindestens zweier in Längsrichtung annähernd durchgehender Kanäle auf einem Übertragungszylinder werden eine Vielzahl von Möglichkeiten zur Anordnung von Aufzügen, beispielsweise Drucktüchern geschaffen.Due to the arrangement of at least two longitudinally approximately continuous Channels on a transfer cylinder are used in a variety of ways Arrangement of lifts, created for example blankets.

Es ist vorteilhaft, Formzylinder und Übertragungszylinder so anzuordnen, dass der Kanal des Formzylinders auf einem Kanal des Übertragungszylinders abrollt.It is advantageous to arrange the form cylinder and transfer cylinder so that the channel of the forme cylinder rolls on a channel of the transfer cylinder.

Wesentlich ist die Ausbildung der Aufzüge für den Übertragungszylinder als mehrlagiges oder mehrschichtiges Drucktuch, welches eine Trägerplatte und eine mit dieser verbundenen Auflage bzw. Schicht aufweist. Insbesondere bei großen Dimensionen ist für ein über den Umfang des Zylinders konstant gute und registergenaue Druckqualität eine möglichst dimensionsstabile Ausbildung vorteilhaft.Essential is the design of the lifts for the transfer cylinder as a multilayer or multilayer blanket, which has a backing plate and one with this having associated support or layer. Especially for large dimensions is for an over the circumference of the cylinder constantly good and register accurate print quality preferably dimensionally stable training advantageous.

Vorteilhaft ist auch die Ausbildung der Kanäle mit einer schmalen Öffnung zur Mantelfläche des Zylinders hin, z. B. zur Reduzierung des Papierverbrauchs. Für Kanäle des Formzylinders ist eine schmale Öffnung besonders vorteilhaft, insbesondere für Kanäle, welche zumindest zu einem Teil abgedeckt sind. Beispielsweise kann hierdurch die Bruchgefahr weiter verringert werden.Also advantageous is the formation of the channels with a narrow opening to Lateral surface of the cylinder, z. B. to reduce paper consumption. For channels of the forme cylinder is a narrow opening particularly advantageous, especially for Channels which are at least partially covered. For example, this can the risk of breakage is further reduced.

Weiterhin ist es vorteilhaft das Umfangsverhältnis des Übertragungs- zum Formzylinder ganzzahlig auszuführen und die Kanäle auf dem Zylinder in Umfangsrichtung symmetrisch anzuordnen.Furthermore, it is advantageous the circumferential ratio of the transmission to the forme cylinder integral and the channels on the cylinder in the circumferential direction symmetrical to arrange.

Ein Druckwerk einer Rotationsdruckmaschine weist mindestens ein Zylinderpaar 01 bestehend aus zwei Zylindern 02; 03, beispielsweise einem Übertragungszylinder 02 und einem mit diesem zusammen wirkenden Formzylinder 03 auf. Der Übertragungszylinder 02 kann über den zu bedruckenden Bedruckstoff 04 mit einem nicht dargestellten Gegendruckzylinder oder aber mit einem Übertragungszylinder 07 eines zweiten Zylinderpaares 06 zusammen wirken, dem seinerseits ein Formzylinder 08 zugeordnet ist. Die Übertragungszylinder 02; 07 sind jeweils mit mindestens zwei in Umfangsrichtung hintereinander angeordneten Aufzügen 09, beispielsweise Drucktüchern 09, und die Formzylinder 03; 08 jeweils mit mindestens einem Aufzug 11, beispielsweise einer Druckform 11, belegbar.A printing unit of a rotary printing press has at least one pair of cylinders 01 consisting of two cylinders 02; 03, for example, a transfer cylinder 02 and a cooperating with this form cylinder 03. The transfer cylinder 02 can be printed on the substrate to be printed 04 with a not shown Impression cylinder or with a transfer cylinder 07 of a second Cylinder pair 06 act together, which in turn is associated with a forme cylinder 08. The transfer cylinder 02; 07 are each with at least two in the circumferential direction successively arranged elevators 09, for example blankets 09, and the Form cylinder 03; 08 each with at least one elevator 11, for example one Printing form 11, assignable.

Je nach Anforderung an die Druckformate und die Druckleistung, sowie die Möglichkeiten in der Papierführung sind die Zylinderpaare 01; 06 verschieden breit ausgeführt. Beispielsweise sind die Zylinderpaare 01; 06 für den Zeitungsdruck doppelt- oder dreifach breit ausgeführt, wobei einfach breit die Breite des Ballens, beispielsweise des Formzylinders 03, für zwei stehende oder liegende Zeitungsseiten bezeichnet. Im Akzidenzdruck wird unter doppeltbreit die erforderliche Breite für vier liegende oder sechs stehende A4-Seiten bezeichnet. Die Umfänge der Übertragungs- 02; 07 und der Formzylinder 03; 08 sind jeweils einfach oder doppelt ausgeführt, bezogen auf unterschiedlichste stehende oder liegende Formate, beispielsweise auf ein stehendes oder liegendes Zeitungsformat. Vorteilhafte Konstellationen im Zeitungsdruck sind beispielsweise ein doppelt großer Umfang, d. h. zwei Seiten in Umfangsrichtung, beim Übertragungszylinder 02; 07 zusammen wirkend mit einem doppelten oder einfachen Umfang beim Formzylinder 03; 08, jeweils doppelt breit.Depending on the requirements of the print formats and the printing performance, as well as the possibilities in the paper guide, the cylinder pairs 01; 06 different widths executed. For example, the cylinder pairs 01; 06 for newspaper printing double or three times wide, with just wide the width of the bale, such as the Form cylinder 03, for two standing or lying newspaper pages called. in the Commercial printing will be under double the required width for four or six standing A4 pages. The sizes of transmission 02; 07 and the Form cylinder 03; 08 are each made simple or double, based on Different standing or lying formats, for example, on a stationary or lying newspaper format. Advantageous constellations in newspaper printing are for example, twice the size, i. H. two sides in the circumferential direction, at Transfer cylinder 02; 07 acting together with a double or simple Circumference of the forme cylinder 03; 08, each double width.

Fig. 1 zeigt ein doppelt breites Zylinderpaar 01, wobei der nicht beanspruchte Übertragungszylinder 02 und der Formzylinder 03 jeweils einen doppelten Umfang aufweisen. Der Formzylinder 03 weist zwei in Längsrichtung verlaufende und in Umfangsrichtung voneinander beabstandete Kanäle 12; 13 zur Aufnahme der Enden mindestens einer Druckform 11, der Übertragungszylinder 02 einen Kanal 14 zur Aufnahme der Enden mindestens eines Drucktuches 09 auf. Die Kanäle 12; 13 des Formzylinders 03, 08 sind zumindest auf einem Teilabschnitt in Längsrichtung des Formzylinders 03; 08, in einem senkrecht zur Rotationsachse liegenden Querschnitt betrachtet, in Umfangsrichtung hintereinander angeordnet. Der Formzylinder 03 ist im Beispiel mit vier in Längsrichtung des Zylinders nebeneinander angeordneten Druckformen 11, beispielsweise Druckplatten 11 belegt, die jeweils mit ihren beiden Enden im Kanal 12 gehalten sind, sich bis auf den Bereich des Kanals 12 jeweils um den gesamten Umfang erstrecken und jeweils den Kanal 13 überdecken. Um einer Bruchgefahr vorzubeugen, sind Formzylinder 03 und Übertragungszylinder 02 vorteilhafter Weise so zueinander angeordnet, dass der überdeckte Kanal 13 beim Abrollen der Zylinder mit dem Kanal 14 des Übertragungszylinders 02 zusammen wirkt. Letzteres ist nicht erforderlich, wenn z. B. der Kanal 13 mittels eines lösbaren Deckels verschließbar ist oder die Kanalbreite so klein ist, dass ein Bruch vermieden wird. Der Formzylinder 03 kann doppelt- und dreifach breit ausgeführt sein. Er kann flexibel auf vielfältige Weise, z. B. mit einer durchgehenden, oder zwei oder mehreren in Längsrichtung nebeneinander angeordneten Druckplatten 11 verschiedenster Formate (z. B. einfach, Panorama) belegt sein. Im Bedarfsfall kann der Formzylinder 03 auch mehr als zwei in Längsrichtung verlaufende und in Umfangsrichtung voneinander beabstandete Kanäle 12; 13 aufweisen. Der nicht erfindungsgemäße Übertragungszylinder 02 der Fig. 1 kann einen durchgehenden Kanal 14 aufweisen, in dem in axialer Richtung nebeneinander zwei Drucktücher 09 gehalten sind. Es können jedoch auch zwei in axialer Richtung nebeneinander, jedoch zueinander versetzte, z. B. um 180°, Kanälen 14; 16 angeordnet sein, wobei die nebeneinander angeordneten Drucktücher ebenfalls zueinander versetzt angeordnet sind (nicht explizit dargestellt, zweiter Kanal 16 wäre in Fig. 1 verdeckt und nicht sichtbar).Fig. 1 shows a double-wide cylinder pair 01, wherein the unclaimed Transfer cylinder 02 and the forme cylinder 03 each have a double circumference exhibit. The forme cylinder 03 has two longitudinally extending and in Circumferentially spaced channels 12; 13 for receiving the ends at least one printing plate 11, the transfer cylinder 02 a channel 14 for Receiving the ends of at least one blanket 09 on. The channels 12; 13 of the Form cylinder 03, 08 are at least on a section in the longitudinal direction of the Form cylinder 03; 08, in a cross-section perpendicular to the axis of rotation considered arranged in the circumferential direction one behind the other. The forme cylinder 03 is in Example with four arranged side by side in the longitudinal direction of the cylinder Printing forms 11, for example, printing plates 11 occupied, each with their two Ends are held in the channel 12, except for the area of the channel 12 each to the extend the entire circumference and each cover the channel 13. To one To prevent the risk of breakage, form cylinder 03 and transfer cylinder 02 advantageously arranged to each other so that the covered channel 13 at Rolling the cylinder with the channel 14 of the transfer cylinder 02 cooperates. The latter is not required if z. B. the channel 13 by means of a detachable lid is closable or the channel width is so small that a break is avoided. Of the Form cylinder 03 can be made twice and three times wide. He can be flexible diverse way, z. B. with one continuous, or two or more in Longitudinally juxtaposed printing plates 11 different formats (eg simple, panorama). If necessary, the forme cylinder 03 can also do more as two longitudinal and circumferentially spaced apart Channels 12; 13 have. The non-inventive transfer cylinder 02 of FIG. 1 may have a continuous channel 14 in which in the axial direction next to each other two blankets 09 are held. However, there may be two in axial Direction next to each other, but staggered, z. B. by 180 °, channels 14; 16 be arranged, wherein the juxtaposed blankets also are arranged offset to each other (not explicitly shown, second channel 16 would be in Fig. 1 hidden and not visible).

Auch der Übertragungszylinder 02 weist, wie beispielhaft in Fig. 2 an einem nicht unter das beanspruchte Druckwerk fallenden Übertragungszylinder 02 gezeigt, einen zweiten, z. B. diametral gegenüber liegenden und in Längsrichtung des Übertragungszylinder 02 verlaufenden Kanal 16 auf. Die Kanäle 14; 16 des Übertragungszylinders 02, 07 sind zumindest auf einem Teilabschnitt in Längsrichtung des Übertragungszylinders 03; 08, in einem senkrecht zur Rotationsachse liegenden Querschnitt betrachtet, in Umfangsrichtung hintereinander angeordnet. Im nicht erfindungsgemäßen Beispiel überdeckt ein einziges, sich bis auf den Bereich des Kanals 14 über die gesamte Länge des Ballens und nahezu über den gesamten Umfang erstreckendes Drucktuch 09 den Übertragungszylinder 02. Der Formzylinder ist hier beispielhaft mit zwei in Längsrichtung des Zylinders nebeneinander liegenden, und sich jeweils um nahezu den vollen Umfang erstreckenden Druckplatten 11 belegt. Der überdeckte Kanal 13 wirkt im Beispiel beim Abrollen des Zylinderpaares 01 mit dem ebenfalls überdeckten Kanal 16 des Übertragungszylinders 02 zusammen. Er kann jedoch, wie im ersten Ausführungsbeispiel, auf dem nicht überdeckten Kanal 14 abrollen.Also, the transfer cylinder 02 has, as exemplified in Fig. 2 at a not under the claimed printing unit falling transfer cylinder 02 shown a second, z. B. diametrically opposite and in the longitudinal direction of the transfer cylinder 02nd extending channel 16. The channels 14; 16 of the transfer cylinder 02, 07 are at least on a section in the longitudinal direction of the transfer cylinder 03; 08, in viewed in a direction perpendicular to the axis of rotation cross-section, in Circumferentially arranged one behind the other. In the example not according to the invention covers a single, down to the area of the channel 14 over the entire length the bale and almost over the entire circumference extending blanket 09 the Transfer cylinder 02. The form cylinder is exemplary here with two in the longitudinal direction the cylinder next to each other, and each to almost the full extent extending printing plates 11 occupied. The covered channel 13 acts in the example at Rolling of the cylinder pair 01 with the also covered channel 16 of the Transfer cylinder 02 together. However, he can, as in the first embodiment, unroll on the uncovered channel 14.
