Description

Die Erfindung betrifft eine Vorrichtung zum Aufbringen einer Hülse auf einen Zylinder, insbesondere einer als Druckform dienenden oder gummibeschichteten Hülse auf den Zylinder einer Offset-Rotationsdruckmaschine, mit einer die Hülse durch eine Öffnung in der Druckwerkseitenwand achsparallel dem Zylinder zuführenden Hilfsvorrichtung, die vor der Freigabe des Achszapfenlagers in dieser Seitenwand mit einer Halterung den Zylinder stützt, wonach die Hülse über das Achszapfenlager auf den Zylinder aufschiebbar ist.The invention relates to a device for applying a sleeve to a cylinder, in particular a serving as a printing form or rubber-coated sleeve on the cylinder of an offset rotary printing press, with an auxiliary device which feeds the sleeve through an opening in the printing unit side wall, axially parallel to the cylinder, before the release of the Axle journal bearing in this side wall supports the cylinder with a bracket, after which the sleeve can be pushed onto the cylinder via the axle journal bearing.

Eine derartige Vorrichtung ist aus der DE-PS 470 937 für eine Rotationstiefdruckmaschine bekannt. Dort wird ein in der einen Druckwerkseitenwand angeordneter, das Achszapfenlager erfassender Träger in der Ebene der Druckwerkseitenwand abgesenkt, nachdem zuvor von einer die Hülse achsparallel zum Druckwerkzylinder zuführenden Hilfseinrichtung der Zylinder erfaßt, d.h. abgestützt wurde. Dadurch kann die Hülse über das Achszapfenlager auf den Tiefdruckzylinder aufgeschoben werden. Anschließend wird der Träger wieder gegen das Achszapfenlager hochgefahren und die Hilfsvorrichtung entfernt. Wie diese Vorveröffentlichung offenbart und auch allgemein bekannt ist, müssen derartige Tiefdruckzylinder nicht verschwenkt werden, so daß sie ortsfest in den beiden Druckwerkseitenwänden gelagert werden können. Die Druckträgerbahn ist mittels an die Tiefdruckzylinder anstellbaren Walzen, sogenannten Presseuren, in üblicher Weise bedruckbar. Sollen beispielsweise derartige Hülsen auf Druckwerkzylinder aufgebracht werden, die zur Anstellung an weitere benachbarte Druckwerkzylinder verstellbar, d.h. üblicherweise exzentrisch gelagert werden müssen, so ist eine sichere Aufbringung mit dieser bekannten Vorrichtung nicht angezeigt.Such a device is known from DE-PS 470 937 for a rotogravure printing machine. There, a carrier arranged in the printing unit side wall and grasping the journal bearing is lowered in the plane of the printing unit side wall after the cylinder has previously been gripped by an auxiliary device that supplies the sleeve parallel to the axis of the printing unit cylinder, i.e. was supported. This allows the sleeve to be pushed onto the gravure cylinder via the journal bearing. The carrier is then raised again against the journal bearing and the auxiliary device is removed. As this prior publication discloses and is also generally known, rotogravure cylinders of this type do not have to be pivoted so that they can be stored in a stationary manner in the two printing unit side walls. The print carrier web can be printed in the usual way by means of rollers, so-called impression rollers, which can be adjusted to the gravure cylinders. If, for example, sleeves of this type are to be applied to printing couple cylinders which are adjustable for engagement with other adjacent printing couple cylinders, i.e. Usually have to be stored eccentrically, safe application with this known device is not indicated.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Aufbringen von Hülsen auf verstellbar, vorzugsweise exzentrisch in Druckwerkseitenwänden gelagerte Zylinder aufzuzeigen, wie sie beispielsweise als Form- und/oder Gummi(Offset)zylinder in Hochdruck-, Flexodruck- und Offsetdruckmaschinen Verwendung finden, wobei sichergestellt werden soll, daß sich während des Aufbringvorganges der Achsabstand zu einem benachbarten Zylinder nicht verändert. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen schematisch:

  • Fig. 1 Einen exzentrisch gelagerten Druckwerkzylinder,
  • Fig. 2 eine Hilfsvorrichtung zum Aufbringen einer Hülse auf den in Fig. 1 dargestellten Druckwerkzylinder,
  • Fig. 3 und 4 in Seitenansicht die Lagerung von Druckwerkzylindern, auf die Hülsen aufgebracht werden sollen und
  • Fig. 5 die Auführungsformen gemäß Fig. 3 in einer anderen Ansicht.
The object of the invention is to provide a device for applying sleeves to adjustable, preferably eccentrically mounted cylinders in the printing unit side walls, as are used, for example, as form and / or rubber (offset) cylinders in high-pressure, flexographic and offset printing machines, thereby ensuring should be that the center distance to an adjacent cylinder does not change during the application process. This object is achieved by applying the features of the characterizing part of claim 1. Further developments of the invention result from the subclaims and from the description in conjunction with the drawings. These show schematically:
  • 1 an eccentrically mounted printing cylinder,
  • 2 shows an auxiliary device for applying a sleeve to the printing group cylinder shown in FIG. 1,
  • 3 and 4 in side view the storage of printing unit cylinders to be applied to the sleeves and
  • Fig. 5 shows the embodiment of FIG. 3 in another view.

Gemäß der schematischen Darstellung nach Fig. 1 wird zwischen zwei Druckwerkseitenwänden 1, 2 ein Zylinder, beispielsweise ein sogenannter Offsetzylinder 3 mit einer Gummibeschichtung über seine Achszapfen 4, 5 gelagert. Solche Zylinder müssen zwecks Anstellung an andere Zylinder, z.B. an einen Plattenzylinder und/oder an einen Gegendruckzylinder verschieb- bzw. verschwenkbar gelagert sein, weshalb auf den Achszapfen 4, 5 über Lager 8, 9 in Umfangsrichtung verdrehbare Exzenter 11, 12 verwendet werden, die ihrerseits in in den Druckwerkseitenwänden 1, 2 vorgesehenen Seitenwandöffnungen 6, 7 positioniert sind. Für den Antrieb des Zylinders 3 ist an dem verlängerten über die Druckwerkseitenwand 2 hinausragenden Achszapfen 4 ein üblicherweise schräg verzahntes Antriebszahnrad 10 aufgezogen. In den dargestellten Ausführungsformen ist jeweils nur ein Exzenter gezeigt, jedoch versteht es sich, daß für entsprechende Verstell- bzw. Bewegungsmöglichkeiten auch zwei übereinanderliegende Exzenter im Rahmen der Erfindung zur Anwendung kommen können.According to the schematic representation according to FIG. 1, a cylinder, for example a so-called offset cylinder 3 with a rubber coating, is mounted between two printing unit side walls 1, 2 via its axle journals 4, 5. Such cylinders have to be used against other cylinders, e.g. be mounted on a plate cylinder and / or on an impression cylinder so as to be displaceable or pivotable, which is why eccentrics 11, 12 which can be rotated in the circumferential direction on bearings 4, 5 via bearings 8, 9 are used, which in turn are provided in side wall openings provided in printing unit side walls 1, 2 6, 7 are positioned. For driving the cylinder 3, a drive gear 10, which is usually helically toothed, is mounted on the elongated axle journal 4 which projects beyond the printing unit side wall 2. In the illustrated embodiments, only one eccentric is shown, but it goes without saying that two eccentrics lying one above the other can also be used within the scope of the invention for corresponding adjustment or movement possibilities.

Zur Durchführung der erfindungsgemäßen Maßnahmen ist es erforderlich, daß eine Druckwerkseitenwand, hier die Druckwerkseitenwand 1 eine Seitenwandöffnung 7 aufweisen muß, deren Durchmesser dw größer als der Durchmesser D des Druckwerkzylinders 3 ist, wobei der Durchmesser dL einer auf den Lagern, hier dem Lager 9 angeordneten Buchse oder Exzenter 11 kleiner als der Durchmesser D des Druckwerkzylinders ist. Die Ausbildung und Anordnung auf der anderen Seite, d.h. an der Druckwerkseitenwand 2 kann im Prinzip in bekannter Weise erfolgen, jedoch können auch hier Teilmerkmale der Erfindung, wie noch im nachfolgenden beschrieben wird, angewendet werden.To carry out the measures according to the invention, it is necessary for a printing unit side wall, here the printing unit side wall 1, to have a side wall opening 7 whose diameter dw is greater than the diameter D of the printing unit cylinder 3, the diameter dL being arranged on the bearings, here the bearing 9 Bushing or eccentric 11 is smaller than the diameter D of the printing unit cylinder. The formation and arrangement on the other hand, i.e. In principle, the printing unit side wall 2 can be made in a known manner, but partial features of the invention can also be used here, as will be described below.

Gemäß der Erfindung ist in oder an der Seitenwand 1 ein Backenfutter 13 vorgesehen, das mindestens zwei Backen aufweisen muß. Bei der Ausführungsform gemäß Fig. 1 ist ein Dreibackenfutter zweckmäßig. Das Backenfutter 13 ist in Richtung des Doppelpfeiles 14 in der Ebene der Druckwerkseitenwand 1 gegenläufig verschiebbar, um das Aufbringen der in Fig. 2 angedeuteten Hülse 15 durch die Wandöffnung 7 zu ermöglichen. Wird eine Hülse auf den Plattenzylinder einer Offset-Rotationsdruckmaschine oder auf den Formzylinder einer Flexo- oder Hochdruckmaschine aufgebracht, so trägt diese ein durch z.B. chemische Behandlung erzeugtes Druckbild. Wird die Hülse 15, wie gemäß Fig. 1, 2, auf einen Gummituchzylinder (Offsetzylinder) einer Offset-Rotationsdruckmaschine aufgebracht, so ist sie mit einer Gummischicht versehen, die beispielsweise aufvulkanisiert sein kann.According to the invention, a jaw chuck 13 is provided in or on the side wall 1, which must have at least two jaws. In the embodiment according to FIG. 1, a three-jaw chuck is useful. The jaw chuck 13 can be displaced in the opposite direction in the direction of the double arrow 14 in the plane of the printing unit side wall 1 in order to enable the sleeve 15 indicated in FIG. 2 to be applied through the wall opening 7. If a sleeve is applied to the plate cylinder of an offset rotary printing machine or to the form cylinder of a flexographic or high-pressure machine, this is entered by e.g. chemical treatment generated print image. If the sleeve 15, as shown in FIGS. 1, 2, is applied to a blanket cylinder (offset cylinder) of an offset rotary printing press, it is provided with a rubber layer, which can be vulcanized on, for example.

Vor dem Aufschieben der Hülse 15 auf den Zylinder 3 muß von der Seite her an die Druckwerkseitenwand eine Hilfsvorrichtung 16 angesetzt werden, die beispielsweise über nicht näher bezeichnete Räder herangefahren werden kann. Diese trägt auf einem zylindrischen Träger 17 die auf den Zylinder 3 aufzuschiebende Hülse 15. An diesem ist eine Halterung 18 angeordnet, die im einfachsten fall aus einer Spitze bestehen kann, die in eine entsprechende Vertiefung 19 am Zapfen 5 eingreift, um beim Aufschiebevorgang den Zylinder 3 an der linken Seite zu halten. Danach kann das Backenfutter 13 auseinandergefahren werden, so daß die Hülse 15 durch die Seitenwandöffnung 7 hindurch auf den Zylinder 3 aufgeschoben werden kann. Aus zeichnerischen Gründen ist in Fig. 2 der Träger 17 und die Hülse 15 etwas kürzer dargestellt.Before the sleeve 15 is slid onto the cylinder 3, an auxiliary device 16 must be attached from the side to the printing unit side wall, which can be moved up, for example, by means of wheels that are not specified. This carries on a cylindrical support 17 to be pushed onto the cylinder 3 sleeve 15. On this a holder 18 is arranged, which in the simplest case can consist of a tip which engages in a corresponding recess 19 on the pin 5 to the cylinder during the sliding process 3 on the lin to keep one side. Then the jaw chuck 13 can be moved apart so that the sleeve 15 can be pushed onto the cylinder 3 through the side wall opening 7. For drawing reasons, the carrier 17 and the sleeve 15 are shown somewhat shorter in FIG. 2.

Gemäß der Erfindung ist es wesentlich, daß vor der Entlastung, d.h. vor der Freigabe der Lagerung des Achszapfens 5 eine auf dem Lager 9 angeordnete Hülse bzw. Exzenter 12 in Umfangsrichtung fixiert wird, und zwar in einer umnfangsmäßigen Stellung, die für die gewünschte axiale Lage bzw. den erforderlichen Achsmittelabstand zu einem oder mehreren benachbarten Zylindern eingestellt wird, um die Hülse 15 aufschieben zu können. Gemäß Fig. 1 kann die umfangsmäßige Fixierung des dort gezeigten Exzenters 12 dadurch erreicht werden, daß der Exzenter 12 vor dem Auseinanderfahren des Backenfutters 13 durch eine mechanische oder magnetische oder sonstige gegebenenfalls eine Längenveränderung ermöglichende Halte- bzw. Fixiervorrichtung mit der Druckwerkseitenwand 1 oder mit dem Backenfutter 13 verbunden wird. Eine solche bei 57 angedeutete Verriegelung kann beispielsweise durch eine Scheibenbremse oder mit Hilfe von eleketromagnetischen Einrichtungen erfolgen.According to the invention it is essential that prior to unloading, i.e. Before the bearing of the axle 5 is released, a sleeve or eccentric 12 arranged on the bearing 9 is fixed in the circumferential direction, in a circumferential position which is set for the desired axial position or the required center-to-center distance from one or more adjacent cylinders to be able to slide on the sleeve 15. 1, the circumferential fixation of the eccentric 12 shown there can be achieved in that the eccentric 12 before the jaw chuck 13 is moved apart by a mechanical or magnetic or other holding or fixing device, which possibly allows a change in length, with the printing unit side wall 1 or with the Jaw chuck 13 is connected. Such locking, indicated at 57, can take place, for example, by means of a disc brake or with the aid of electromagnetic devices.

Durch die Verriegelung bzw. umfangsmäßige Fixierung des Exzenters 12 ist sichergestellt, daß der Achsmittelabstand des Zylinders 3 während des Aufschiebevorganges zu weiteren Zylindern beibehalten wird. Nach dem Aufschieben der Hülse 15 auf den Druckwerkzylinder 3 kann die Hilfsvorrichtung 16 wieder zurückgefahren werden, nachdem zuvor das Backenfutter 13 wieder zusammengefahren und die Verriegelung 57 gelöst wurde. Es ist zweckmäßig zur geringfügigen Aufweitung der Hülse 15, beispielsweise mittels aus dem Zylindermantel des Zylinders 3 ausströmender Druckluft, den Aufschiebevorgang zu erleichtern. Gegebenfalls kann auch eine Stütze 20 verwendet werden, die etwa in der Mitte des Zylinder 3 in Richtung des Pfeiles 21 in den Zylinder 3 angestellt werden kann, um zu Beginn des Aufschiebevorganges diesen zu stützen bis die Hülse 15 weit genug aufgeschoben ist. Bei genügend langer Hilfsvorrichtung 16 kann jedoch gegebenenfalls auf die Stütze 20 verzichtet werden.The locking or circumferential fixation of the eccentric 12 ensures that the center-to-center distance of the cylinder 3 is maintained during the pushing-on process to other cylinders. After the sleeve 15 has been pushed onto the printing unit cylinder 3, the auxiliary device 16 can be moved back again after the jaw chuck 13 has been moved together again and the locking mechanism 57 has been released. It is expedient for the slight expansion of the sleeve 15, for example by means of compressed air flowing out of the cylinder jacket of the cylinder 3, to facilitate the sliding-on process. If necessary, a support 20 can also be used, which can be placed approximately in the middle of the cylinder 3 in the direction of arrow 21 in the cylinder 3 in order to support it at the beginning of the pushing-on process until the sleeve 15 has been pushed on far enough. If the auxiliary device 16 is long enough, however, the support 20 may be dispensed with.

In den Fig. 3 bis 5 ist eine Zylinderkonfiguration für eine Offset-Rotationsdruckmaschine gezeigt. Der hier als Offset- bzw. als Gummizylinder ausgebildete Zylinder 3 ist, ebenso wie die weiteren verwendeten Zylinder, in den Wandöffnungen 6, 7 der Druckwerkseitenwände 1, 2 positioniert.3 to 5, a cylinder configuration for an offset rotary printing press is shown. The cylinder 3 designed here as an offset or rubber cylinder, like the other cylinders used, is positioned in the wall openings 6, 7 of the printing unit side walls 1, 2.

Dem als Offsetzylinder verwendeten Zylinder 3 ist ein Gegendruckzylinder 22 und ein Plattenzylinder 23 zugeordnet. Durch die exzentrische Lagerung des Zylinders 3 kann dieser zumindest an den Plattenzylinder 23 und gegebenenfalls auch an den Gegendruckzylinder 22 angestellt werden. Es kann aber auch der Gegendruckzylinder 21 mittels einer entsprechenden exzentrischen Lagerung an den Zylinder 3 herangefahren werden, um eine zwischen diesen durchlaufende Druckträgerbahn 24 zu bedrucken.An impression cylinder 22 and a plate cylinder 23 are assigned to the cylinder 3 used as the offset cylinder. Due to the eccentric mounting of the cylinder 3, the latter can be placed at least on the plate cylinder 23 and possibly also on the impression cylinder 22. However, the counter-pressure cylinder 21 can also be moved to the cylinder 3 by means of a corresponding eccentric bearing in order to print on a print carrier web 24 passing between them.

In der Druckwerkseitenwand 1 sind gemäß den Fig. 4, 5 in deren Öffnung 7 seitlich verschiebbare Backen 27, 28 für den Zylinder 3 und 29, 30 für den Plattenzylinder 23 positioniert. Diese Anordnung kann auch außen an der Druckwerkseitenwand angesetzt werden, wenn dies aufgrund der bestehenden Platzverhältnisse erforderlich ist. Die Backenfutter 27, 28 bzw. 29, 30 sind in der Öffnung 7 der Druckwerkseitenwand 1 gegenläufig verschiebbar, wie durch die Doppelpfeile 31, 32 angedeutet wurde. Gemäß den Fig. 3 bis 5 ist auf dem dort mit 25 bezeichneten Zapfen des Zylinders 3 wenigstens ein Exzenter 33 angeordnet, mit dessen Hilfe der Zylinder 3 in seine An- und seine Abstellpositionen 34, 34' gebracht werden kann. Es versteht sich, daß, wie in Fig. 5 gezeigt, auch auf der anderen Seite des Zylinders eine entsprechende exzentrische Lagerung hierfür erforderlich wird.4, 5 laterally displaceable jaws 27, 28 for the cylinder 3 and 29, 30 for the plate cylinder 23 are positioned in the opening 7 of the printing unit. This arrangement can also be applied to the outside of the printing unit side wall if this is necessary due to the available space. The jaw chucks 27, 28 and 29, 30 are displaceable in opposite directions in the opening 7 of the printing unit side wall 1, as was indicated by the double arrows 31, 32. According to FIGS. 3 to 5, at least one eccentric 33 is arranged on the pin of the cylinder 3, designated 25, by means of which the cylinder 3 can be brought into its on and off positions 34, 34 '. It is understood that, as shown in Fig. 5, a corresponding eccentric bearing is required for this on the other side of the cylinder.

Auf dem Zapfen 25 ist ein ringförmiger Ansatz 35 vorgesehen, auf dem die Verriegelungs- bzw. Blockiervorrichtung in Form einer Kupplung oder einer Bremse 36 positioniert ist, die gegen die Innenbohrung des Exzenters wirkt, d.h. daß bei deren Aktivierung eine umfangsmäßige Blockierung des Exzenters 33 auf dem Achszapfen 25 erfolgt. Diese Blockierung erfolgt gemäß den vorangehenden Ausführungen im Rahmen der Erfindung jeweils vor der Freigabe der Achszapflagerung, d.h. vor dem Auseinanderfahren der Backen 27, 28 gemäß Fig. 4. In vorteilhafter Weise können die Backen 27 und 28 für den Zylinder 3 und die Backen 29, 30 für den Plattenzylinder 23 dadurch gegenläufig verschoben werden, daß an diesen und an der Seitenwandöffnung 7 Verzahnungen 37, 37' bzw. 38, 38' angebracht werden, in die jeweils ein verzahnter Antrieb, beispielsweise Stirnräder 40, 41, 42, 43 eingreifen. Bei deren Verdrehung in eine vorgegebene Richtung ist somit die gegenläufige Verschiebung der Backen 27 bis 30 möglich. Es kann zweckmäßig sein, die benachbarten oberen Backenbereiche durch einen Spalt zu trennen, wie bei 39 angedeutet wurde.An annular extension 35 is provided on the pin 25, on which the locking or blocking device is positioned in the form of a clutch or a brake 36 which acts against the inner bore of the eccentric, i.e. that when activated, there is a circumferential blocking of the eccentric 33 on the journal 25. This blocking takes place in accordance with the preceding statements within the scope of the invention in each case before the axle journal bearing is released, i.e. before the jaws 27, 28 move apart as shown in FIG. 4. In an advantageous manner, the jaws 27 and 28 for the cylinder 3 and the jaws 29, 30 for the plate cylinder 23 can be displaced in opposite directions by having 7 toothings on them and on the side wall opening 37, 37 'and 38, 38' are attached, in each of which a toothed drive, for example spur gears 40, 41, 42, 43, engage. When they are rotated in a predetermined direction, the opposing displacement of the jaws 27 to 30 is possible. It may be expedient to separate the adjacent upper jaw areas by a gap, as indicated at 39.

Wie die Fig 3 bis 5 erkennen lassen, ist hier lediglich der mittlere Zylinder 3 exzentrisch gelagert, während zumindest der Plattenzylinder 23 lediglich eine exzentrische Lagerung aufweist, was ausreichend ist, da dieser nicht verstellt wird. Doch ist im Rahmen der Erfindung auch hier der erfindungsgemäße Aufbau der Lagerung und die Aufschiebung einer Hülse möglich. Oberhalb des Plattenzylinders 23 sind einige Auftragwalzen 44, 45 eines nicht näher dargestellten Farb- und/oder Feuchtwerkes angedeutet.As can be seen from FIGS. 3 to 5, here only the middle cylinder 3 is mounted eccentrically, while at least the plate cylinder 23 only has an eccentric bearing, which is sufficient since this is not adjusted. However, within the scope of the invention, the construction of the mounting according to the invention and the pushing on of a sleeve are also possible here. Above the plate cylinder 23, some applicator rollers 44, 45 of an inking and / or dampening unit, not shown, are indicated.

Es ist zweckmäßig, auch auf der anderen Seite des Zylinders 3, d.h. in oder an der Druckwerkseitenwand 2 eine Blockierung der zuvor beschriebenen Weise beim Aufziehen bzw. Aufscnieben einer Hülse vorzusehen. Hierdurch wird vermieden, daß sich der Achszapfen 48 über das Lager 49 in der Exzenterbüchse 50 sich im Rahmen des Zahnspieles verdreht, das be abgestelltem Zylinder 3 relativ groß sein kann. Deshalb ist auch hier wiederum ein Ansatz 57 vorhanden, auf dem eine Bremse oder Kupplung 58 angeordnet ist, die gegen die Innenbohrung des Exzenters 50 wirkt und diesen umfangsmäßig am Lagerzapfen 48 fixiert. Zur Verstellung der Exszenterbüchsen 33 und 50 sind jeweils entsprechende Mittel vorgesehen, die, wie bei 46 und 47 angedeutet wurde, Motoren sein können, die über eine Verzahnung mit den Exzentern 33, 50 in Eingriff stehen, so daß die erforderlichen An- und Abstellvorgänge durchgeführt werden können. Wie der untere Teil von Fig. 4 erkennen läßt, werden diese Exzenterverstellung 46, die an den Backen 28 angeordnet sind, mit auseinandergefahren, was vorteilhaft ist.It is expedient to provide for blocking on the other side of the cylinder 3, that is to say in or on the printing unit side wall 2, when a sleeve is being pulled open or snapped open. This avoids that the journal 48 on the bearing 49 in the eccentric bushing 50 rotates within the scope of the backlash, which can be turned off cylinder 3 can be relatively large. Therefore, here again there is an extension 57 on which a brake or clutch 58 is arranged, which acts against the inner bore of the eccentric 50 and this circumferentially fixed on the bearing journal 48. Appropriate means are provided for adjusting the eccentric bushes 33 and 50, which, as indicated at 46 and 47, can be motors which engage with the eccentrics 33, 50 via a toothing, so that the required starting and stopping processes are carried out can be. As can be seen in the lower part of FIG. 4, this eccentric adjustment 46, which are arranged on the jaws 28, are moved apart, which is advantageous.

Der Plattenzylinder ist gemäß Fig. 5 über seine Achszapfen 51, 54 über Lager 52, 55 in Buchsen 53, 56 positioniert, wobei die Buchse 56 im Backen 29 angeordnet ist, so daß in der vorangehend beschriebenen Weise auch die Aufbringung einer Hülse auf den Plattenzylinder 23 erfolgen kann. Nach Fig. 5 erfolgt der Antrieb der Zylinder 3, 23 in herkömmlicher Weise über Zahnräder, wobei das auf dem Achszapfen 48 angeordnete Zahnrand mit 59 bezeichnet wurde.The plate cylinder is positioned according to FIG. 5 via its axle journals 51, 54 via bearings 52, 55 in bushes 53, 56, the bush 56 being arranged in the jaws 29, so that the application of a sleeve to the plate cylinder is also carried out in the manner described above 23 can be done. 5, the cylinders 3, 23 are driven in a conventional manner via gearwheels, the toothed rim arranged on the journal 48 being designated 59.

Werden die Exzenter 12 an der Druckwerkseitenwand 1 oder an dem auseinanderfahrbaren Backenfutter 13 umfangsmäßig fixiert, so sollten sie einen zwei- oder mehrgeteilten Aufbau aufweisen.If the eccentrics 12 are fixed circumferentially on the printing unit side wall 1 or on the jaw chuck 13 which can be moved apart, they should have a two-part or multi-part construction.

Eine weitere vorteilhafte umfangmäßige Fixierung der Exzenter (z.B. 12) ist dadurch möglich, daß vorzugsweise an der Stirnseite des Zylinders 17 eine gegen den Exzenter 12 anstellbare Blockierung 60, z.B. in Form einer Spitze oder Bremse, vorgesehen wird, die beim Anfahren, d.h. Ansetzen der Hilfsvorrichtung 16 möglichst formschlüssig den Exzenter 12 festhält.A further advantageous, extensive fixing of the eccentrics (e.g. 12) is possible in that a blocking 60, e.g. in the form of a tip or brake, which is provided when starting, i.e. Attaching the auxiliary device 16 holds the eccentric 12 as positively as possible.
