Description

Die Erfindung betrifft ein Farb- und Feuchtwerk für ein umsteuerbares Druckwerk einer Rotations-Offsetdruckmaschine nach der im Oberbegriff des Anspruchs 1 genannten Gattung.The invention relates to an inking and dampening unit for a reversible printing unit of a rotary offset printing machine according to the type mentioned in the preamble of claim 1.

Ein derartiges umsteuerbares Druckwerk ist beispielsweise aus der CH-PS 557 238 bekannt. Im Farbwerk dieses Druckwerkes sind zwei zentrale Reibwalzen angeordnet, die über umstellbare Uebertragungswalzen miteinander verbindbar sind. Dabei wird die erste zentrale Reibwalze über eine Anzahl Farbwalzen, die die Farbe von einer Duktorwalze erhalten, eingefärbt. Die zweite zentrale Reibwalze erhält die Farbe von einer Uebertragungswalze, die mit beiden zentralen Reibzylindern in Anlage kommt. Die andere Uebertragungswalze verbindet die zweite zentrale Reibwalze mit einer weiteren Reibwalze, die die Farbe auf eine Auftragwalze überträgt. Symmetrisch zur zweiten zentralen Reibwalze ist ebenfalls eine Reibwalze angeordnet, die ihrerseits in Kontakt steht mit einer weiteren Auftragwalze. Die beiden Uebertragungswalzen sind auf um die zweite zentrale Reibwalze schwenkbaren Winkelhebeln drehbar gelagert. Die beiden Uebertragungswalzen stehen ständig in Kontakt mit der zweiten zentralen Reibwalze. In einer ersten Stellung verbindet eine Uebertragungswalze die erste zentrale Reibwalze mit der zweiten zentralen Reibwalze, während die andere Uebertragungswalze die zweite zentrale Reibwalze mit einer weiteren Reibwalze verbindet. Die symmetrische Reibwalze und die zugehörige Auftragwalze sind vom Farbfluss ausgeschaltet, und übernehmen die Aufgabe der Feuchtung, da den beiden symmetrischen Reibwalzen je ein Feuchtwerk zugeordnet ist. Beim gemeinsamen Umschwenken der Uebertragungswalzen erfolgt der Farbfluss über die andere Reibwalze, während die erstere Reibwalze die Feuchtung übernimmt.Such a reversible printing unit is known for example from CH-PS 557 238. In the inking unit of this printing unit, two central friction rollers are arranged, which can be connected to one another via convertible transfer rollers. The first central rubbing roller is inked over a number of inking rollers that receive the ink from a duct roller. The second central distribution roller receives the ink from a transfer roller, which comes into contact with both central distribution cylinders. The other transfer roller connects the second central distribution roller to another distribution roller, which transfers the ink to an application roller. Also arranged symmetrically to the second central distribution roller is a distribution roller, which in turn is in contact with another application roller. The two transfer rollers are rotatably mounted on angle levers pivotable about the second central friction roller. The two transfer rollers are in constant contact with the second central friction roller. In a first position, a transfer roller connects the first central distribution roller with the second central distribution roller, while the other transfer roller connects the second central distribution roller with another distribution roller. The symmetrical distribution roller and the associated application roller are switched off by the ink flow, and take on the task of dampening, since a dampening unit is assigned to each of the two symmetrical distribution rollers. When the transfer rollers are pivoted together, the ink flow takes place via the other distribution roller, while the former distribution roller takes over the dampening.

Mit dieser Einrichtung kann der Plattenzylinder immer vorgefeuchtet werden, d.h. das Feuchtmittel wird vor der Farbe auf den Plattenzylinder gebracht, auch wenn die Drehrichtung des Plattenzylinders umgekehrt wird. Dieses Vorfeuchten ist in manchen Fällen wünschenswert.With this device, the plate cylinder can always be pre-moistened, i.e. the dampening solution is applied to the plate cylinder before the ink, even if the direction of rotation of the plate cylinder is reversed. This pre-wetting is desirable in some cases.

Die Farb- und Feuchtwerkskonfiguration lässt nur diese eine Art der Zuführung des Feuchtmittels auf den Plattenzylinder zu, die sogenannte direkte Einfeuchtung.The ink and dampening unit configuration only allows this type of dampening solution supply to the plate cylinder, the so-called direct moistening.

Eine indirekte Feuchtung, d.h. dass das Feuchtmittel sowohl dem Plattenzylinder, als auch in das Farbwerk hinein aufgebracht wird, ist mit dieser Anordnung nicht möglich.Indirect dampening, i.e. With this arrangement it is not possible for the dampening solution to be applied both to the plate cylinder and into the inking unit.

Beim Wechsel von einer Druckfarbe auf eine andersfarbige muss das Farbwerk gereinigt werden, was normalerweise automatisch geschieht. Dabei müssen auch die Feuchtwerkswalzen gereinigt werden. Hierzu wird beispielsweise an eine der zentralen Reibwalzen eine Wascheinrichtung angestellt. Um ein Reinigen aller Farb- und Feuchtwerkswalzen zu ermöglichen, müsste die Reinigung über den Plattenzylinder erfolgen. Dies hat aber den Nachteil, dass ein schnelles und gründliches Reinigen der Farbwerk- und Feuchtwerkswalzen nicht möglich ist.When changing from one ink to another, the inking unit has to be cleaned, which normally happens automatically. The dampening unit rollers must also be cleaned. For this purpose, a washing device is placed on one of the central friction rollers, for example. To enable cleaning of all inking and dampening unit rollers, the cleaning would have to be carried out via the plate cylinder. However, this has the disadvantage that quick and thorough cleaning of the inking unit and dampening unit rollers is not possible.

Die Aufgabe der Erfindung besteht nun darin, die Farb- und Feuchtwerkswalzen eines umstellbaren Druckwerkes derart anzuordnen, dass die vielfältigen und produktabhängigen Feuchtmittelzuführmöglichkeiten gewährleistet sind, dass ein automatisches Waschen der Farbwerks- und Feuchtwerkswalzen schnell und gründlich durchführbar ist und dass auch bei einer Voreinfärbung der Farbwerkswalzen die Möglichkeit besteht, eine Feuchtung ins Farbwerk vornehmen zu können.The object of the invention is now to arrange the inking and dampening unit rollers of a convertible printing unit in such a way that the diverse and product-dependent fountain solution supply options are ensured that the inking unit and dampening unit rollers are automatically washed can be carried out quickly and thoroughly and that even if the inking unit rollers are pre-inked, there is the possibility of being able to wet the inking unit.

Erfindungsgemäss erfolgt die Lösung dieser Aufgabe durch die in der Kennzeichnung des Anspruchs 1 enthaltenen Merkmale.According to the invention, this object is achieved by the features contained in the characterizing part of claim 1.

Durch das Anordnen der Uebertragswalzen auf Schwenkhebeln, die um die erste Reibwalze bezw. zweite Reibwalze schwenkbar sind, und die demzufolge einzeln an die zentrale Reibwalze an- und abstellbar sind, ergibt sich die Möglichkeit, die unterschiedlichen Varianten der Einfeuchtung des Druckwerks und des Farbwerks zu gewährleisten.By arranging the transfer rollers on swivel levers which bezw around the first friction roller. second friction roller can be pivoted, and which consequently can be individually adjusted and disengaged from the central friction roller, there is the possibility of ensuring the different variants of the dampening of the printing unit and the inking unit.

Es ist aber auch denkbar, die erste und die zweite Uebertragswalze in je zwei Walzenschlössern zu lagern, die mit Linearantrieben ausgerüstet sind, mit welchen die beiden Uebertragungswalzen an die zentrale Reibwalze an- und abgestellt werden können. Die Linearantriebe können vorzugsweise in tangentialer Richtung zur ersten bezw. zweiten Reibwalze angeordnet sein. Es ist auch vorteilhaft, in jedem Walzenschloss einen weiteren Linearantrieb in radialer Richtung zur ersten bezw. zweiten Reibwalze anzubringen, um auch die Lage der entsprechenden Uebertragswalze zur ersten bezw. Reibwalzen einstellen zu können.However, it is also conceivable to store the first and the second transfer roller in two roller locks each, which are equipped with linear drives with which the two transfer rollers can be turned on and off on the central friction roller. The linear drives can preferably be in the tangential direction to the first. second friction roller may be arranged. It is also advantageous to place a further linear drive in the radial direction of the first one in each roller lock. to attach the second roller to also the position of the corresponding transfer roller relative to the first one. To be able to adjust friction rollers.

Eine Feuchtung des Farbwerks während des Voreinfärbvorgangs beim vom Plattenzylinder abgestellten Auftragswalzen ist möglich. Dadurch wird bereits beim Voreinfärben des Farbwerks im Farbwerk ein Farbe-Wasser-Gleichgewicht geschaffen, was dann bei Produktionsbeginn zu weniger Makulatur führt.It is possible to dampen the inking unit during the pre-inking process with the application roller set off the plate cylinder. This creates an ink-water balance when the inking unit is pre-inked in the inking unit, which then leads to less waste at the start of production.

In vorteilhafterweise werden als Feuchtwerke sogenannte kontaktlose Feuchtwerke verwendet. Dies können beispielsweise kontaktlose Bürstenfeuchtwerke oder kontaktlose Sprühfeuchtwerke sein. Diese haben den Vorteil, dass sie nicht in direktem Kontakt mit einer Walze stehen müssen, und demzufolge unabhängig von einem Verstellweg einer Walze diese einfeuchten können.So-called contactless dampening systems are advantageously used as dampening units. These can be, for example, contactless brush dampening systems or contactless spray dampening systems. These have the advantage of being do not have to be in direct contact with a roller, and consequently can dampen it regardless of an adjustment path of a roller.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing and described in more detail below.

Das in Fig. 1 dargestellte Druckwerk besteht aus einem Gummituchzylinder 1, der mit einem weiteren Zylinder 2, der als Gegendruckzylinder oder Gummituchzylinder eines benachbarten Druckwerks ausgebildet ist, und einem Plattenzylinder 3. Die Papierbahn 4, die zwischen Gummituchzylinder 1 und Zylinder 2 hindurchläuft, bewegt sich beim hier dargestellten rechtsdrehenden Gummituchzylinder 1 von oben nach unten.The printing unit shown in Fig. 1 consists of a blanket cylinder 1, which with another cylinder 2, which is designed as a impression cylinder or blanket cylinder of an adjacent printing unit, and a plate cylinder 3. The paper web 4, which runs between the blanket cylinder 1 and cylinder 2, moves the right-handed blanket cylinder 1 shown here from top to bottom.

An den Plattenzylinder 3 ist eine erste Auftragswalze 5 angestellt. Die erste Auftragswalze 5 steht in Kontakt mit einer ersten Reibwalze 6. Um die Drehachse der ersten Reibwalze 6 ist stirnseitig je ein Schwenkhebel 7 schwenkbar angeordnet, auf welchen die erste Uebertragswalze 8 frei drehbar gelagert ist. Die erste Uebertragswalze 8 ist durch das Stellglied 11 von der zentralen Reibwalze 9 abgestellt und erhält über ein kontaktloses Feuchtwerk 10 das Feuchtmittel aufgesprüht. Die erste Uebertragswalze 8, die erste Reibwalze 6 und die erste Auftragswalze 5 übertragen das Feuchtmittel auf den Plattenzylinder 3, man erhält so die gewünschte Vorfeuchtung.A first applicator roller 5 is set on the plate cylinder 3. The first applicator roller 5 is in contact with a first friction roller 6. A swivel lever 7 is pivotally arranged on each end about the axis of rotation of the first distributor roller 6, on which the first transfer roller 8 is freely rotatably mounted. The first transfer roller 8 is switched off from the central friction roller 9 by the actuator 11 and receives the dampening solution sprayed on via a contactless dampening unit 10. The first transfer roller 8, the first friction roller 6 and the first application roller 5 transfer the dampening solution to the plate cylinder 3, thus obtaining the desired pre-wetting.

Die zweite Uebertragswalze 12, die ihrerseits in Schwenkhebeln 14 frei drehbar gelagert ist, welche schwenkbar um die zweite Reibwalze 22 angeordnet sind, ist mittels des Stellgliedes 15 an die zentrale Reibwalze 9 angestellt. Die zentrale Reibwalze 9 wird über die umstellbare Farbwalze 16, über die Farbfilmwalze 17, über den Farbduktor 18, auf welchem die Farbe über Farbmesser, angeordnet im Farbmesserbalken 19, dosiert wird, und über die Schöpfwalze 20, welche in die Farbe in der Farbwanne 21 eintaucht, in bekannter Weise eingefärbt.The second transfer roller 12, which in turn is freely rotatably mounted in pivoting levers 14 which are arranged pivotably about the second distribution roller 22, is set against the central distribution roller 9 by means of the actuator 15. The central rubbing roller 9 is moved over the convertible inking roller 16, over the inking film roller 17, over the inking roller 18, on which the ink is metered via inking knife, arranged in the inking knife bar 19, and over the scoop roller 20, which is in the ink in the inking tank 21st dipped in, dyed in a known manner.

Die zweite Uebertragungswalze 12 überträgt somit die Farbe von der zentralen Reibwalze 9 auf die zweite Reibwalze 22, von wo sie über die zweite Auftragwalze 23 auf den Plattenzylinder 3 auftragen wird. Das Feuchtwerk 24 ist in dieser Betriebsart des Druckwerkes nicht in Betrieb.The second transfer roller 12 thus transfers the ink from the central distribution roller 9 to the second distribution roller 22, from where it is applied to the plate cylinder 3 via the second application roller 23. The dampening unit 24 is not in operation in this operating mode of the printing unit.

Zwischen der ersten Auftragwalze 5 und der zweiten Auftragwalze 23 ist eine zusätzliche Farbauftragwalze 25 angeordnet, die mit der zentralen Reibwalze 9 in Kontakt steht und somit den Plattenzylinder 3 miteinfärbt. In dieser in Fig. 1 dargestellten Funktionsweise für rechtsdrehenden Gummituchzylinder 1 erfüllen die Walzen 8, 6 und 5 voll die Funktion von reinen Feuchtwerkswalzen, während die Walzen 12, 22 und 23 voll die Funktion von reinen Farbwerkswalzen erfüllen. Man erhält somit eine für den Zeitungsdruck optimale direkte Vorfeuchtung des Plattenzylinders 3.Between the first applicator roller 5 and the second applicator roller 23, an additional inking roller 25 is arranged, which is in contact with the central friction roller 9 and thus inks the plate cylinder 3. In this mode of operation shown in Fig. 1 for right-handed blanket cylinder 1, the rollers 8, 6 and 5 fully perform the function of pure dampening unit rollers, while rollers 12, 22 and 23 fully fulfill the function of pure inking unit rollers. This results in optimal pre-wetting of the plate cylinder 3 for newspaper printing.

Fig. 2 zeigt dasselbe Druckwerk wie Fig. 1, aber für einen linksdrehenden Gummituchzylinder 1. Um auch bei dieser Betriebsart die optimale direkte Vorfeuchtung des Plattenzylinders 3 zu erhalten, wird die erste Uebertragswalze 8 an die zentrale Reibwalze 9 angestellt.Fig. 2 shows the same printing unit as Fig. 1, but for a left-handed blanket cylinder 1. In order to obtain the optimal direct pre-moistening of the plate cylinder 3 in this operating mode, the first transfer roller 8 is placed against the central friction roller 9.

Das An- bezw. Abstellen erfolgt hier über einem im nichtdargestellten Walzenschloss angeordneten Linearantrieb 31, der pneumatisch oder elektrisch angetrieben sein kann.The offer Parking takes place here via a linear drive 31 arranged in the roller lock (not shown), which can be pneumatically or electrically driven.

Demgegenüber wird die zweite Uebertragswalze 12 von der zentralen Reibwalze 9 abgestellt. Auch hier erfolgt das An-bezw. Abstellen über einen im nichtdargestellten Walzenschloss angeordneten Linearantrieb 32, elektrisch oder pneumatisch angetrieben. Das Feuchtwerk 10 wird ausser Betrieb gesetzt. Die Walzen 8, 6 und 5 erfüllen somit die volle Funktion von Farbwerkswalzen, die Walzen 12, 22 und 23 werden als reine Feuchtwerkswalzen eingesetzt.In contrast, the second transfer roller 12 is turned off by the central friction roller 9. This is also the case here. Parking via a linear drive 32 arranged in the roller lock (not shown), electrically or pneumatically driven. The dampening unit 10 is put out of operation. The rollers 8, 6 and 5 thus fulfill the full function of inking unit rollers, the rollers 12, 22 and 23 are used as pure dampening unit rollers.

Insbesondere die beiden mit einer harten oder hartelastischen Oberfläche versehenen Reibwalzen 6 und 22, müssen sowohl die Funktion als Feuchtwalze als auch die Funktion als Farbwalze erfüllen. Versuche haben gezeigt, dass mit einer Oberfläche aus Kupfer diese doppelte Funktion sehr gut erfüllt. Es wäre auch denkbar, diese beiden Reibwalzen 6 und 22 aus einem geeigneten Kunststoff oder einem keramischen Werkstoff herzustellen.In particular, the two rubbing rollers 6 and 22, which are provided with a hard or hard-elastic surface, must fulfill both the function as a dampening roller and the function as an inking roller. Tests have shown that with a surface made of copper this double function is very well fulfilled. It would also be conceivable to produce these two friction rollers 6 and 22 from a suitable plastic or a ceramic material.

Da in der Betriebsart nach Fig. 2 auch die zentrale Reibwalze 9 die Drehrichtung gegenüber der Betriebsart nach Fig. 1 umkehrt, Schöpfwalze 20, Farbduktor 18, Farbfilmwalze 17 und die umstellbare Farbwalze 16 aber immer dieselbe Drehrichtung aufweisen sollen, ist deshalb die umstellbare Farbwalze 16 von der zentralen Reibwalze 9 abstellbar und an eine Farbwalze 26 anstellbar, welche in ständigem Kontakt mit der zentralen Reibwalze 9 steht. Dadurch ist die Bewegungsumkehr ausgleichbar.Since the central friction roller 9 in the operating mode according to FIG. 2 also reverses the direction of rotation compared to the operating mode according to FIG. 1, scoop roller 20, ink duct roller 18, ink film roller 17 and the convertible inking roller 16 should always have the same direction of rotation, therefore the reversible inking roller 16 can be set down from the central distribution roller 9 and adjusted to an inking cylinder 26 which is in constant contact with the central distribution roller 9. The reversal of movement can thus be compensated for.

Insbesondere für heikle Drucksujets ist es vorteilhaft, wenn der Plattenzylinder 3 indirekt eingefeuchtet werden kann. In Fig. 3 ist diese Betriebsart dargestellt. Der Gummituchzylinder 1 ist rechtsdrehend. Sowohl die erste Uebertragswalze 8 als auch die zweite Uebertragswalze 12 sind an die zentrale Reibwalze angestellt, dienen demzufolge als Farbwalzen. Das Feuchtwerk 10 ist in Betrieb und feuchtet die erste Uebertragswalze ein. Das Feuchtmittel gelangt somit ins eigentliche Farbwerk, aber auch über die Walze 6 und 5 direkt auf den Plattenzylinder 3.In particular for delicate printing subjects, it is advantageous if the plate cylinder 3 can be moistened indirectly. This operating mode is shown in FIG. 3. The blanket cylinder 1 is clockwise. Both the first transfer roller 8 and the second transfer roller 12 are set against the central friction roller and consequently serve as ink rollers. The dampening unit 10 is in operation and dampens the first transfer roller. The dampening solution thus gets into the actual inking unit, but also directly onto the plate cylinder 3 via the rollers 6 and 5.

Bevor mit einem derartigen Druckwerk die Druckproduktion aufgenommen wird, wird zur Einsparung von Makulatur das Farbwerk voreingefärbt. Zu diesem Zweck, wie dies in Fig. 4 dargestellt ist, wiederum für einen rechtsdrehenden Gummituchzylinder 1, sind die Auftragwalzen 5, 25 und 23 vom Plattenzylinder 3 abgestellt. Die erste Uebertragswalze 8 ist von der zentralen Reibwalze 9 abgestellt. Die zweite Uebertragwalze 12 ist an die zentrale Reibwalze 9 angestellt. Sämtliche Farbwerkswalzen werden nun durch Drehenlassen der Druckeinheit voreingefärbt. Zu diesem Zwecke können die Farbschrauben im Farbmesserbalken 19 ab Scanner entsprechend dem zu druckenden Sujet voreingestellt werden. Möglich ist aber auch, die Farbschrauben auf einen Mittelwert zu stellen. Mit dem Voreinfärben der Farbwerkswalzen wird das Ziel verfolgt, bei Druckbeginn wenig Makulatur zu erhalten. Diese Makulatur kann nochmals reduziert werden, wenn bereits beim Voreinfärben ein Farbe-Feuchtmittel-Gleichgewicht im Farbwerk geschaffen wird. Hierzu wird die erste Uebertragungswalze 8 kurzzeitig an die zentrale Reibwalze 9 angestellt, das Feuchtwerk 10 wird in Betrieb gesetzt und somit wird die erforderliche Menge Feuchtmittel ins Farbwerk abgegeben.Before printing production is started with such a printing unit, the inking unit is pre-inked to save waste. For this purpose, as shown in FIG. 4, again for a right-handed blanket cylinder 1, the application rollers 5, 25 and 23 are set off from the plate cylinder 3. The first transfer roller 8 is switched off from the central friction roller 9. The second transfer roller 12 is placed against the central friction roller 9. All inking rollers are now pre-inked by letting the printing unit rotate. For this purpose, the ink screws in the ink knife bar 19 can be preset from the scanner according to the subject to be printed. However, it is also possible to set the color screws to an average. With the pre-inking of the inking unit rollers, the aim is to minimize waste at the start of printing. This waste can be reduced again if a color-dampening solution balance is created in the inking unit during pre-inking. For this, the first transfer roller 8 briefly placed on the central friction roller 9, the dampening unit 10 is put into operation and thus the required amount of dampening solution is released into the inking unit.

Bei Druckbeginn werden die Auftragwalzen 5, 25 und 23 an den Plattenzylinder angestellt. Und weil im Farbwerk bereits ein Gleichgewicht Farbe-Feuchtmittel geschaffen wurde, erhält man sehr schnell einwandfreie Druckprodukte.At the start of printing, the application rollers 5, 25 and 23 are placed on the plate cylinder. And because an ink-fountain solution balance has already been created in the inking unit, you can get perfect printed products very quickly.

Es ist klar, dass die in Fig. 3 und Fig. 4 dargestellten Betriebsarten für rechtsdrehenden Gummituchzylinder 1 durch symmetrisches Vertauschen der Walzenstellungen auch für linksdrehenden Gummituchzylinder 1 einsetzbar sind.It is clear that the operating modes shown in FIGS. 3 and 4 for right-handed blanket cylinder 1 can also be used for left-handed blanket cylinder 1 by symmetrically interchanging the roller positions.

Bei Druckende oder wenn mit einer anderen Farbe gedruckt werden soll, muss das Farb- und Feuchtwerk gereinigt werden. Dies geschieht im vorliegenden Fall mit einer zustellbaren Wascheinrichtung 30 automatisch und ist in Fig. 5 dargestellt. Zum Waschen werden die Auftragwalzen 5, 25 und 23 vom Plattenzylinder 3 abgestellt. Die in bekannter Weise zustellbare Wascheinrichtung 30 besteht aus einem Aufsprühbalken 27, einer Rakel 28 und einem Auffangbecken 29 zum Auffangen der abgerakelten Reinigungsflüssigkeit. Die erste Uebertragswalze 8 und die zweite Uebertragswalze 12 sind beide an die zentrale Reibwalze 9 angestellt. Die auf die zentrale Reibwalze 9 aufgesprühte Reinigungsflüssigkeit wird schnell über alle Farb- und Feuchtwalzen verteilt. Die an die zentrale Reibwalze 9 zurückgelangende Reinigungsflüssigkeit wird vollständig von der Rakel 28 abgerakelt und dem Auffangbecken 29 zugeführt. Mit den in der beschriebenen Art gestellten Walzen ist ein schnelles und gründliches Waschen von Farbwerk und Feuchtwerk gemeinsam möglich.At the end of printing or when printing with a different color, the inking and dampening unit must be cleaned. In the present case, this is done automatically with an deliverable washing device 30 and is shown in FIG. 5. For washing, the application rollers 5, 25 and 23 are turned off by the plate cylinder 3. The washing device 30, which can be delivered in a known manner, consists of a spray bar 27, a doctor blade 28 and a collecting basin 29 for collecting the scraped-off cleaning liquid. The first transfer roller 8 and the second transfer roller 12 are both employed on the central friction roller 9. The cleaning liquid sprayed onto the central friction roller 9 is quickly distributed over all inking and dampening rollers. The cleaning liquid returning to the central friction roller 9 is completely doctored off by the doctor blade 28 and fed to the collecting basin 29. With the rollers provided in the manner described, a quick and thorough washing of the inking unit and dampening unit is possible together.

Möglich ist es auch, zuerst nur die Farbwerkswalzen zu waschen, was dadurch geschieht, dass die Feuchtwerkswalzen durch Abstellen der entsprechenden Uebertragswalze 8 oder 12 abgekuppelt sind. Wenn die Farbwerkswalzen sauber sind, kann das Feuchtwerk durch Anstellen der entsprechenden Uebertragswalze 8 oder 12 an die zentrale Reibwalze 9 zugekuppelt werden. Nun wird auch das Feuchtwerk noch gewaschen. Mit diesem Vorgang wird eine eventuelle Einfärbung der Feuchtwerkswalzen durch Restfarbe der Farbwerkswalzen verhindert.It is also possible to wash only the inking unit rollers first, which happens because the dampening unit rollers are uncoupled by turning off the corresponding transfer roller 8 or 12. When the inking rollers are clean, the dampening unit can be coupled to the central friction roller 9 by positioning the corresponding transfer roller 8 or 12. Now the dampening system is still being washed. This process prevents possible inking of the dampening unit rollers due to residual ink on the inking unit rollers.

Die Waschung erfolgt immer in der in Fig. 5 angegebenen Drehrichtung der Walzen. Selbstverständlich sind die Feuchtwerke 10 und 24 nicht in Betrieb.The washing is always carried out in the direction of rotation of the rollers shown in FIG. 5. Of course, the dampening units 10 and 24 are not in operation.
