Bei dieser Lösung geraten automatisch bei Anstellung der oberen bzw. unteren Plätten bzw. Gummituchzylinder auch immer die Gummituchzylinder untereinander in Kontakt. Diese zwangsweise Koppelung der Gummituchzylinderverstellung erschwert die Automatisierung des Druckformwechsels nicht unerheblich. Die zwischen den Gummituchzylindern im Druckwerk verbleibende Materialbahn kann beim Druckformwechsel bzw. beim Aufbringen der Druckform auf den Plattenzylinder reißen, was ein aufwendiges Wiedereinführen der Materialbahn und damit Zeitverlust zur Folge hat.With this solution, the top and bottom plates or Blanket cylinder always the blanket cylinder in contact with each other. This Forced coupling of the blanket cylinder adjustment makes automation more difficult the printing form change is not insignificant. The between the blanket cylinders in the The web of material remaining in the printing unit can change the printing form or apply it tear the printing form on the plate cylinder, which is a complex reintroduction of the Material web and thus loss of time.

Abhilfe kann zwar dadurch geschaffen werden, das untere bzw. die Gummituchhülse am unteren Gummituchzylinder zu entfernen, um die Druckform am oberen Plattenzylinder auszutauschen und umgekehrt - allein dies ist ebenfalls eine zeitraubende Lösung.Remedy can be created by the lower or the rubber blanket sleeve on Lower blanket cylinder to remove the printing form on the upper plate cylinder exchange and vice versa - this alone is also a time-consuming solution.

Ausgehend vom skizzierten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Verstellung der oberen bzw. unteren Druckwerkzylinder zu ermöglichen, ohne daß eine im Druckwerk befindliche Materialbahn im Spalt zwischen den Gummizylindern beschädigt wird.Starting from the outlined prior art, the invention is based on the object To allow adjustment of the upper or lower printing cylinder without an Material web located in the printing unit in the gap between the rubber cylinders damaged becomes.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the features of patent claim 1.

Durch die erfindungsgemäße Lösung ergibt sich in vorteilhafter Weise die Möglichkeit, bei im Druckwerk verbleibender Materialbahn sowohl in der unteren als auch in der oberen Druckeinheit die Druckform auszutauschen. Da die jeweiligen Druckwerkzylinder in der oberen bzw. in der unteren Druckeinheit aneinander angestellt bzw. voneinander abgestellt werden können, ohne daß der Spalt zwischen den Oberflächen der Übertragungszylinder, durch welchen die Bahn geführt ist, beeinträchtigt wird, können die Druckformen unter Ausnutzung des Andrückeffektes durch die jeweils abgestellten Übertragungszylinder vorgespannt und fertig aufgespannt werden. Die Rißgefahr für die Materialbahn besteht nicht mehr, ein Neueinfädeln der Materialbahn kann entfallen.The solution according to the invention advantageously gives the possibility of Material web remaining in the printing unit in both the lower and the upper Printing unit to replace the printing form. Since the respective printing cylinder in the in the upper or in the lower printing unit without the gap between the surfaces of the transfer cylinders, through which the web is guided, the printing forms can be affected Exploitation of the pressure effect by the respective switched off transfer cylinder pre-tensioned and fully tensioned. There is no risk of tearing for the material web more, there is no need to re-thread the material web.

In weiteren Ausgestaltungen des der Erfindung zugrunde liegenden Gedankens hebt eine Stelleinheit den in einer ersten Stellposition des oberen Druckformzylinders gebildeten oberen Spalt zum Übertragungszylinder unabhängig von der Stellung der Übertragungszylinder auf oder erzeugt eben diesen. Dadurch kann am oberen Druckwerk die Druckform ausgewechselt werden, ohne die Stellposition der den Spalt für die Materialbahn bildenden Übertragungszylinder zu verändern.In further refinements of the idea on which the invention is based, a Actuator the upper formed in a first position of the upper printing plate cylinder Gap to the transfer cylinder regardless of the position of the transfer cylinder or creates this. This allows the printing plate to be replaced on the upper printing unit without the position of the gap forming the material web Change transfer cylinder.

Besagte Stelleinheit hebt außerdem den in einer ersten Stellposition des unteren Druckwerkzylinders gebildeten unteren Spalt zum unteren Übertragungszylinder unabhängig von der Stellung dieses Übertragungszylinders auf oder erzeugt eben diesen. Die den Spalt für die Materialbahn aufrechterhaltende Zusatzstelleinheit kann der oberen Druckeinheit, der unteren Druckeinheit des Druckwerkes wie auch einer unteren Druckwerkzylinderlagerung zugeordnet sein. Die Zusatzstelleinheit ist in allen drei vorgenannten Fällen so plaziert, daß die Bewegung der Übertragungszylinder - die der Materialbahn nächstgelegene Zylinder - unterbunden bleibt.Said actuating unit also lifts the one in a first actuating position of the lower one Printing unit cylinder formed lower gap to the lower transfer cylinder independently from the position of this transfer cylinder or just generates this. The gap for the additional web unit maintaining the material web can the upper printing unit, the lower printing unit of the printing unit as well as a lower printing unit cylinder bearing be assigned. The additional control unit is placed in all three cases mentioned above in such a way that the movement of the transfer cylinders - the cylinders closest to the material web - remains prevented.

Die obere Druckeinheit 3 besteht aus einem oberen Druckwerkzylinder 5 - dem oberen Druckformzylinder - um eine Achse 10 rotierend, sowie einem oberen Übertragungszylinder 6, der jedoch in einer gehäusefesten Lagerung 14 aufgenommen ist und um eine Achse 11 rotiert. Die untere Druckeinheit 4 umfaßt einen unteren Übertragungszylinder 7 um eine Achse 12 rotierend, sowie einen unteren Druckformzylinder 8, der um eine Achse 13 rotiert.A double printing unit 2 printing a material web 1 on both sides comprises an upper one Printing unit 3 and a lower printing unit 4. The upper printing unit 3 consists of a upper printing unit cylinder 5 - the upper printing form cylinder - rotating about an axis 10, as well as an upper transfer cylinder 6, which, however, is in a bearing 14 fixed to the housing is recorded and rotates about an axis 11. The lower printing unit 4 includes one lower transfer cylinder 7 rotating about an axis 12, and a lower Printing form cylinder 8, which rotates about an axis 13.

Der obere Druckformzylinder 5 der oberen Druckeinheit 3 ist in einem oberen Dreharm 15 gelagert, der um einen Schwenkpunkt 15.1 bewegbar ist. Der untere Übertragungszylinder 7 der unteren Druckeinheit 4 ist in einem mittleren Dreharm 16 mit einer mittleren Lagerung 19 aufgenommen, wobei der Dreharm 16 um den Drehpunkt 16.1 verschwenkbar ist. Ebenso ist der untere Druckwerkzylinder 8 - der untere Druckformzylinder - in einem unteren Dreharm 17 aufgenommen, der um einen Drehpunkt 17.1 verschwenkbar ist. Im in Fig. 1 dargestellten Zustand sind die beiden Übertragungszylinder 6, 7 der jeweiligen Druckeinheiten 3, 4 voneinander abgestellt und bilden einen Spalt 44, den die Materialbahn 1 passiert. Innerhalb der oberen Druckeinheit 3 befinden sich der obere Druckformzylinder 5 und der obere Übertragungszylinder 6 in voneinander abgestelltem Zustand, so daß ein Spalt 45 in der oberen Druckeinheit 3 erzeugt ist. Der untere Druckformzylinder 8 und der untere Übertragungszylinder 7 der unteren Druckeinheit 4 bilden ebenfalls in voneinander abgestelltem Zustand einen Spalt 46 in der unteren Druckeinheit 4. An der bahneinlaufseitigen Seite des Druckwerkes 2 ist im in Fig. 1 gezeigten Beispiel eine Stelleinheit 21 aufgenommen, die die obere Lagerung 18 des oberen Druckformzylinders 5 mit der unteren Lagerung des unteren Druckformzylinders 8 verbindet. Die Stelleinheit 21 ist als Kolben/Zylinderstelleinheit 22, 23 ausgeführt und wirkt auf eine Kolbenstange 24.The upper printing form cylinder 5 of the upper printing unit 3 is in an upper rotating arm 15 stored, which is movable about a pivot point 15.1. The lower transfer cylinder 7 the lower printing unit 4 is in a middle pivot arm 16 with a middle bearing 19 added, the pivot arm 16 being pivotable about the pivot point 16.1. Likewise the lower printing unit cylinder 8 - the lower printing form cylinder - in a lower one Added pivot arm 17 which is pivotable about a pivot point 17.1. In Fig. 1 State shown are the two transfer cylinders 6, 7 of the respective Printing units 3, 4 are turned off from one another and form a gap 44 which the material web 1 happens. The upper printing form cylinder 5 is located within the upper printing unit 3 and the upper transfer cylinder 6 in the mutually shut-off state, so that a Gap 45 is generated in the upper printing unit 3. The lower plate cylinder 8 and the lower transfer cylinders 7 of the lower printing unit 4 also form one another switched off state, a gap 46 in the lower printing unit 4. On the web entry side On the side of the printing unit 2, in the example shown in FIG. 1, an adjusting unit 21 is accommodated, which is the upper one Bearing 18 of the upper printing form cylinder 5 with the lower bearing of the lower one Printing forme cylinder 8 connects. The actuator 21 is as Piston / cylinder actuating unit 22, 23 executed and acts on a piston rod 24.

Weiterhin ist in Fig. 1 eine Zusatzstelleinheit 25 aufgenommen, die ein translatorisch verschiebbares Stellglied 26 einschließt. Im in Fig. 1 gezeigtem Ausführungsbeispiel ist die Zusatzstelleinheit 25 der oberen Druckeinheit 3 gegenüberliegend angeordnet. Das Stellelement 26 - hier trapezförmig ausgebildet - ist zwischen die gestellfeste Lagerung 14 und die mittleren Lagerung 19, an der eine Anschlagfläche 27 ausgebildet ist, einfahrbar. Dadurch wird im abgestellten Zustand der der Materialbahn 1 nächstgelegenen Übertragungszylinder 6, 7 der Spalt 44 offengehalten. Über die Stelleinheit 21 ist jedoch ein Anstellung des oberen bzw. unteren Druckformzylinders 5, 8 an die durch die Zusatzstelleinheit 25 festgesetzten Übertragungszylinder 6, 7 möglich.

This is the closest to the material web 1 in the parked state Transfer cylinder 6, 7 of the gap 44 kept open. Via the control unit 21 is, however Employment of the upper and lower printing form cylinders 5, 8 to the by Additional actuator 25 fixed transfer cylinder 6, 7 possible.

So kann beispielsweise auf den oberen Druckformzylinder 5 der oberen Druckeinheit 3 eine neue Druckform an deren Vorderkante eingehangen werden. Zum korrekten Aufziehen der Druckform auf die Zylinderoberfläche des oberen Druckformzylinders 5 werden zunächst die beiden Übertragungszylinder 6, 7 durch die Stelleinheit 25 blockiert, d.h. der Spalt 44 wird gesichert, die Materialbahn 1 ist frei. Danach kann der obere Druckformzylinder 5 an den oberen Übertragungszylinder 6 angestellt werden, die Druckform wird durch die Oberfläche des oberen Übertragungszylinders 6 gleichmäßig auf den oberen Druckformzylinder 5 aufgespannt, so daß anschließend eine korrekte die Druckform spannende Hinterkantenklemmung der Druckform erfolgen kann. Die Umfangsfläche des oberen Übertragungszylinders 6 kann so als Anpreßfläche für die neu aufzuziehende Druckform genutzt werden.For example, one can be on the upper printing form cylinder 5 of the upper printing unit 3 new printing form is hung on the front edge. For correct mounting of the Printing form on the cylinder surface of the upper printing form cylinder 5 are the first both transfer cylinders 6, 7 blocked by the actuator 25, i.e. the gap 44 becomes secured, the material web 1 is free. Then the upper plate cylinder 5 to the upper transfer cylinder 6 are used, the printing form is through the surface of the upper transfer cylinder 6 evenly onto the upper printing form cylinder 5 stretched, so that subsequently a correct exciting the printing form Trailing edge clamping of the printing form can take place. The peripheral surface of the top Transfer cylinder 6 can be used as a contact surface for the new printing form be used.

Fig. 2 zeigt ein Doppeldruckwerk mit einer Zusatzstelleinheit, der mittleren Lagerung 19 gegenüberliegend angeordnet.2 shows a double printing unit with an additional setting unit, the middle bearing 19 arranged opposite each other.

In diese Konfiguration eines Doppeldruckwerkes 2 mit ebenfalls zwei Druckeinheiten 3, 4 wird die Materialbahn 1 beidseits bedruckt. Analog zur in Fig. 1 dargestellten Anordnung ist der obere um eine Achse 10 rotierende Druckformzylinder 5 in einem um den Drehpunkt 15.1 gelagerten Dreharm verschwenkbar. Der zur oberen Druckeinheit 3 gehörende obere Übertragungszylinder 6 ist in einer gestellfesten Lagerung 14 aufgenommen. Bei der unteren Druckeinheit 4 verhält es sich analog. Dort ist der untere Druckformzylinder 8 um den Drehpunkt 17.1 verschwenkbar, ebenso wie der untere Übertragungszylinder 7 der unteren Druckeinheit 4 um den Drehpunkt 16.1 bewegbar ist.In this configuration a double printing unit 2 with two printing units 3, 4 the material web 1 is printed on both sides. It is analogous to the arrangement shown in FIG. 1 the upper printing form cylinder 5 rotating about an axis 10 in a around the pivot point 15.1 mounted swivel arm. The upper one belonging to the upper printing unit 3 Transfer cylinder 6 is received in a mounting 14 fixed to the frame. At the bottom Printing unit 4 behaves analogously. There is the lower printing plate cylinder 8 around Pivot point 17.1 is pivotable, as is the lower transfer cylinder 7 of the lower one Printing unit 4 is movable about the pivot point 16.1.

Mittels der Stelleinheit 21, die als Kolben/Zylinderstelleinheit 22, 23 ausgeführt sein kann und auf die Kolbenstange 24 wirkt, werden die Druckwerkzylinder 5, 7 und 8 voneinander ab- bzw. aneinander angestellt, wobei der obere Übertragungszylinder 6 gestellfest gelagert ist. Im hier gezeigten Zustand sind die Oberflächen sämtlicher Druckwerkzylinder 5, 6, 7 und 8 im voneinander abgestellten Zustand dargestellt. Dadurch ist zwischen dem oberen Übertragungszylinder 6 und dem oberen Druckformzylinder 5 ein Spalt 45 gebildet. Ferner besteht nach Abstellung aller Druckwerkzylinder 5, 6, 7 und 8 voneinander, sowohl zwischen den Druckwerkzylinderpaaren einer jeden Druckeinheit 3 bzw. 4 ein oberer bzw. ein unterer Spalt 45, 46. Zwischen den Übertragungszylindern 6 und 7, die beidseits der Materialbahn 1 angeordnet sind, besteht ein Spalt 44, den die Materialbahn 1 passiert und in welchem diese unbeschädigt verbleiben kann, wenn die mittlere Lagerung 19 über die hier dieser zugeordnete Zusatzstelleinheit blockiert wird. Im hier dargestellten Ausführungsbeispiel wird die mittlere Lagerung 19 durch das Stellglied 26, welches hier eine keilförmige Anschlagfläche aufweist, blockiert. Die keilförmige Anschlagfläche des Stellgliedes 26 fährt über einen ebenfalls mit einer keilförmigen Stellfläche versehenen Anschlag 28 an der mittleren Lagerung 19 und hemmt somit deren Schwenkbewegung, so daß der untere Übertragungszylinder 7 in seiner Position verbleibt, um den Spalt 44 offen zu halten, in welchem sich die Materialbahn 1 befindet.By means of the actuating unit 21, which can be designed as a piston / cylinder actuating unit 22, 23 and acts on the piston rod 24, the printing couple cylinders 5, 7 and 8 are separated or adjusted to each other, the upper transfer cylinder 6 being fixed to the frame. in the state shown here are the surfaces of all printing cylinders 5, 6, 7 and 8 in shown from each other. This is between the top Transfer cylinder 6 and the upper printing form cylinder 5, a gap 45 is formed. Further exists after all printing unit cylinders 5, 6, 7 and 8 have been turned off, both between the printing unit cylinder pairs of each printing unit 3 or 4 an upper or a lower one Gap 45, 46. Between the transfer cylinders 6 and 7, which is on both sides of the material web 1st are arranged, there is a gap 44 through which the material web 1 passes and in which this can remain undamaged if the middle bearing 19 via the one assigned here Additional control unit is blocked. In the embodiment shown here, the middle one Bearing 19 by the actuator 26, which here has a wedge-shaped stop surface, blocked. The wedge-shaped stop surface of the actuator 26 also moves with one a wedge-shaped footprint 28 provided on the middle bearing 19 and thus inhibits their pivoting movement, so that the lower transfer cylinder 7 in its Position remains in order to keep the gap 44 open, in which the material web 1 located.

Sobald die Zusatzstelleinheit 25 mittels des Stellgliedes 26 die Bewegung der mittleren Lagerung 19 blockiert hat und somit der Spalt 44 gesichert ist, können der obere bzw. der untere Druckformzylinder 5, 8 an die jeweiligen in ihren Positionen festgestellten Übertragungszylinder 6 bzw. 7 angestellt werden, beim Wechsel der Druckform beispielsweise. Die Möglichkeit, die beiden Druckformzylinder 5, 8 durch die Stelleinheit 21 unabhängig von den Übertragungszylindern 6 und 7 zu bewegen, erlaubt beim Wechsel der Druckform an den Druckformzylindern ein gleichmäßiges Aufbringen der Druckform durch Andrücken der Druckform mittels des jeweiligen Übertragungszylinders 6 oder 7. Dank der voneinander unabhängigen Stelleinheiten 21, 25 lassen sich die Druckformzylinder 5 und 8 unabhängig von der Stellposition der Übertragungszylinder 6 und 7 an- oder abstellen, so daß die Materialbahn 1 im Spalt 44 des Doppeldruckwerkes verbleiben kann.As soon as the additional setting unit 25 uses the actuator 26 to move the middle one Storage 19 has blocked and thus the gap 44 is secured, the upper or lower printing form cylinders 5, 8 to the respective in their positions Transfer cylinder 6 or 7 are turned on when changing the printing form for example. The possibility of the two printing form cylinders 5, 8 through the actuating unit 21 move independently of the transfer cylinders 6 and 7, when changing the allowed Printing form on the printing form cylinders by uniform application of the printing form Press the printing form using the respective transfer cylinder 6 or 7. Thanks to the mutually independent actuating units 21, 25, the printing form cylinders 5 and 8 regardless of the position of the transfer cylinders 6 and 7 on or off, so that the material web 1 can remain in the gap 44 of the double printing unit.

Im in Fig. 2 gezeigten Zustand werden bei Druckanstellung durch die Stelleinheit 21 nach Festsetzung der mittleren Lagerung 19 mittels der Zusatzstelleinheit 25 der untere Spalt 46 durch die Anstellung der unteren Lagerung 20, d.h. des Anschlages 20.1 an einen Anschlag 19.1 der mittleren Lagerung 19 aufgehoben, die Oberflächen des unteren Übertragungszylinders 7 und des unteren Druckformzylinders 8 sind in Kontakt miteinander. In analoger Weise kontaktiert bei Druckanstellung durch die Stelleinheit 21 ein Anschlag 18.1 der oberen Lagerung 18 die Oberseite der gestellfesten Lagerung 14 des oberen Übertragungszylinders 6. Somit kann bei Aufrechterhaltung des Spaltes 44 die Materialbahn 1 im Doppeldruckwerk 2 verbleiben, da die Anstellung der Druckformzylinder 5, 8 bei Druckformwechsel beispielsweise an die Übertragungszylinder 6, 7 eine Änderung von deren Position obsolet macht.In the state shown in FIG. 2, when actuated by the actuating unit 21, after Fixing the middle bearing 19 by means of the additional adjusting unit 25, the lower gap 46 by setting the lower bearing 20, i.e. of the attack 20.1 to one Stop 19.1 of the middle bearing 19 lifted the surfaces of the lower one Transfer cylinder 7 and the lower printing form cylinder 8 are in contact with each other. In an analogous manner, a stop 18.1 makes contact when pressure is set by the actuating unit 21 the upper bearing 18 the top of the fixed bearing 14 of the upper Transfer cylinder 6. Thus, while maintaining the gap 44, the material web 1 remain in the double printing unit 2, since the employment of the printing form cylinders 5, 8 at Change of printing form, for example, to the transfer cylinders 6, 7 a change of theirs Position makes obsolete.

Fig. 3 zeigt ein Doppeldruckwerk 2 mit einer gegenüber der unteren Lagerung 20 angeordneten Zusatzstelleinheit 25.3 shows a double printing unit 2 with a bearing 20 opposite the lower bearing arranged additional control unit 25.

Mit dieser Anordnung kann nach Aktivierung der Zusatzstelleinheit 25 und Ausfahren des Stellgliedes 26 über den Anschlag 29 die untere Lagerung 20 festgesetzt werden. Der Spalt 46 kann demzufolge nur unwesentlich beeinflußt werden - die Anschläge 20.1 und 19.1 bleiben außer Kontakt. Mittels der Stelleinheit 21 kann jedoch der obere Spalt 45 in der oberen Druckeinheit 3 beeinflußt werden, da die obere Lagerung 18 nach wie vor verschwenkbar ist und somit der obere Druckformzylinder 5 an den oberen Übertragungszylinder 6 anstellbar ist, so daß der Spalt 45 dort aufgehoben ist. In der dargestellten Anordnung kann somit der Glättungseffekt beim Aufbringen der Druckform auf die Umfangsfläche des oberen Übertragungszylinders 5 ausgenutzt werden, wohingegen bei der unteren Druckeinheit 4 der Spalt 46 im wesentlichen konstant gehalten wird.With this arrangement, after activating the additional setting unit 25 and extending the Actuator 26, the lower bearing 20 are fixed via the stop 29. The gap 46 can therefore be influenced only insignificantly - the stops 20.1 and 19.1 remain out of contact. By means of the actuating unit 21, however, the upper gap 45 in the upper one Printing unit 3 can be influenced because the upper bearing 18 is still pivotable and thus the upper printing form cylinder 5 can be adjusted to the upper transfer cylinder 6, so that the gap 45 is canceled there. In the arrangement shown, the Smoothing effect when applying the printing form on the peripheral surface of the upper Transfer cylinder 5 are used, whereas in the lower printing unit 4 the Gap 46 is kept substantially constant.

In Fig. 4 schließlich ist eine an den Doppeldruckwerken bahneinlaufseitig montierte Bahnführungseinheit detaillierter wiedergegeben.Finally, in FIG. 4, one is mounted on the web printing end on the double printing units Web guide unit reproduced in more detail.

Die Bahnführungseinheit 30 umfaßt einen oberen Gehäuseteil 41, sowie einen unteren Gehäuseteil 43, in denen ein oberer bzw. ein unterer Schlitten 31, 32 verschiebbar gelagert sind. An den Schlitten 31, 32 sind Schutzelemente 33, 34 angebracht, die an ihren, dem Spalt 44 zuweisenden Enden jeweils eine leichte Krümmung 35, 36 aufweisen, die in etwa der Krümmung der Oberflächen der beiden beidseits der Materialbahn 1 angeordneten Übertragungszylinder 6, 7 entspricht. Die Schutzelemente 33, 34 sind an Lagerungen 37 bzw. 38 der Schlitten 31, 32 aufgenommen, die mit je einer separaten oberen bzw. unteren Stelleinheit 39, 40 betätigbar sind. Die hier nur schematisch angedeuteten Stelleinheiten 39 können sowohl hydraulisch oder pneumatisch betätigte sein, auch Stellmotoren jeglicher Art wären denkbar.The web guide unit 30 comprises an upper housing part 41 and a lower one Housing part 43, in which an upper or a lower slide 31, 32 slidably mounted are. Protective elements 33, 34 are attached to the slide 31, 32, which, on their Gaps 44 facing ends each have a slight curvature 35, 36, which is approximately the Curvature of the surfaces of the two arranged on both sides of the material web 1 Transfer cylinder 6, 7 corresponds. The protective elements 33, 34 are on bearings 37 or 38 of the slides 31, 32, each with a separate upper and lower Actuator 39, 40 are actuated. The actuating units 39 only indicated schematically here can be hydraulically or pneumatically operated, as well as servomotors of any kind would be conceivable.

Mittels der in den Spalt 44 verfahrbaren fingerförmigen Schutzelemente 35, 36 kann eine einzufädelnde Materialbahn 1 von den Oberflächen der Übertragungszylinder 6 und 7 weggehalten werden, so daß diese nicht durch an den Oberflächen anhaftenden Farbreste an den Oberflächen anklebt und sich um die Übertragungszylinder 6 und 7 wickelt. Die Krümmungen 35, 36 der Schutzelemente 33, 34 bilden eine Art trichterförmigen Einlauf, der die Materialbahn 1 auf der Einlaufseite des Spaltes 44 vor dem Kontakt mit den Übertragungszylindern 6, 7 schützt. By means of the finger-shaped protective elements 35, 36 which can be moved into the gap 44, a Material web 1 to be threaded from the surfaces of the transfer cylinders 6 and 7 are kept away so that they do not stick to paint residues adhering to the surfaces sticks to the surfaces and wraps around the transfer cylinders 6 and 7. The Curvatures 35, 36 of the protective elements 33, 34 form a kind of funnel-shaped inlet, which the material web 1 on the inlet side of the gap 44 before contact with the Transfer cylinders 6, 7 protects.
