Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Reinigen einer Walze oder eines Zylinders zu schaffen.The invention has for its object to provide a device for cleaning a roller or a cylinder.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß bei einem vergleichsweise einfachem Aufbau der Vorrichtung eine hohe und zuverlässige Reinigungswirkung erzielbar ist, wobei ein insbesondere flüssiges Reinigungsmittel Verwendung finden kann. Das Reinigungsmittel kann zudem wiederaufbereitet und im Umlauf geführt werden, wobei gleichzeitig eine Selbstreinigung der Vorrichtung ermöglicht ist.The advantages which can be achieved with the invention consist in particular in that a high and reliable cleaning effect can be achieved with a comparatively simple construction of the device, in particular a liquid cleaning agent Can be used.

Im folgenden ist die Erfindung anhand lediglich ein Ausführungsbeispiel zeigender Zeichnungen näher erläutert. Es zeigen:

The invention is explained in more detail below with reference to drawings showing only one exemplary embodiment. Show it:

Die erfindungsgemäße Vorrichtung 01 ist in unmittelbarer Nähe einer zu reinigenden Walze 02 oder Zylinders, beispielsweise eines Formzylinders oder einer Leitwalze einer nicht dargestellten Druckmaschine, angeordnet. Die Vorrichtung 01 weist zunächst einmal ein erstes Trägerelement 03 in Form eines Zahnriemens auf, der über zwei axial beabstandete drehbare Führungselemente in Form von Riemenscheiben 04 bzw. 05 geführt wird. Dadurch wird ein schlaufenartig endlos umlaufendes Trägerelement mit einem zur Walze 02 weisenden ersten Trum 06 und einem von der Walze wegweisenden zweiten Trum 07 gebildet.The device 01 according to the invention is arranged in the immediate vicinity of a roller 02 or cylinder to be cleaned, for example a forme cylinder or a guide roller of a printing machine, not shown. First of all, the device 01 has a first carrier element 03 in the form of a toothed belt, which is guided over two axially spaced rotatable guide elements in the form of pulleys 04 and 05, respectively. As a result, a loop-like, endlessly circulating carrier element is formed with a first strand 06 facing the roller 02 and a second strand 07 pointing away from the roller.

Weiter ist ein nicht dargestellter Antrieb vorgesehen, der mindestens eine der Riemenscheiben 04 oder 05 mit einem Drehmoment beaufschlagt und so einen Antrieb des Zahnriemens 03 in Richtung F einer Längsachse der Walze 02 bewirkt. Die beiden Riemenscheiben 04 und 05, genauer deren senkrecht zur Zeichenebene verlaufende Mittelachsen 08 und 09, weisen einen axialen Abstand auf, der beim hier dargestellten Ausführungsbeispiel im wesentlichen der axialen Länge der zu reinigenden Walze 02 entspricht.Furthermore, a drive, not shown, is provided which applies torque to at least one of the pulleys 04 or 05 and thus drives the toothed belt 03 in the direction F of a longitudinal axis of the roller 02. The two pulleys 04 and 05, more precisely their central axes 08 and 09 running perpendicular to the plane of the drawing, have an axial spacing which, in the exemplary embodiment shown here, corresponds essentially to the axial length of the roller 02 to be cleaned.

Wie insbesondere der Darstellung nach Fig. 2 zu entnehmen ist, ist der Zahnriemen 03 mit Reinigungselementen 10 in Form von stirnbürstenartigen Borstenelementen versehen, die so am Zahnriemen 03 angeordnet sind, daß sie nach radial außen, bezogen auf die durch den Zahnriemen 03 gebildet Schlaufe, weisen. Weiter ist beim dargestellten Ausführungsbeispiel der Zahnriemen 03 nicht über seine gesamt Länge mit Borstenelementen 10 versehen; vielmehr ist der Zahnriemen nur 03 nur über seine halbe Länge beborstet. Dadurch kann der Zahnriemen 03 aus einer Position, in der ein Teil oder im wesentlichen alle der Borstenelemente 10 mit der Oberfläche der zu reinigenden Walze 02 in Eingriff bzw. an dieser zur Anlage gelangen (Arbeitsposition), in die in Fig. 2 gezeigte Position gebracht werden, in der sämtliche Borstenelemente 10 auf dem von der Walze 02 wegweisenden Trum 07 liegen (Ruheposition).2, the toothed belt 03 is provided with cleaning elements 10 in the form of bristle-like bristle elements which are arranged on the toothed belt 03 in such a way that they extend radially outward, with respect to the loop formed by the toothed belt 03, point. Furthermore, in the illustrated embodiment, the toothed belt 03 is not provided with bristle elements 10 over its entire length; rather, the timing belt is bristled only 03 over half its length. As a result, the toothed belt 03 can be brought into the position shown in FIG. 2 from a position in which a part or essentially all of the bristle elements 10 engage with the surface of the roller 02 to be cleaned or come to bear against it (working position) in which all the bristle elements 10 lie on the strand 07 pointing away from the roller 02 (rest position).

Im Bereich des von der Walze 02 wegweisenden Trums 07 ist die Vorrichtung 01 mit einer Reihe hintereinander angeordneter Reinigungskammern 11, 12, 13, 14 und 15 versehen, die nacheinander vom Zahnriemen 03 und damit den Borstenelementen 10 durchlaufen werden. In diesen Reinigungskammern 11, 12, 13, 14 und 15 werden die Borstenelemente 10 von der Oberfläche der Walze 02 aufgenommenen Verunreinigungen zumindest teilweise befreit. Dies kann beispielsweise durch nicht dargestellte Abstreifer erreicht oder zumindest unterstützt werden, die in den jeweiligen Reinigungskammern angeordnet sind.In the area of the strand 07 pointing away from the roller 02, the device 01 is provided with a series of cleaning chambers 11, 12, 13, 14 and 15 arranged one behind the other, through which the toothed belt 03 and thus the bristle elements 10 pass in succession. In these cleaning chambers 11, 12, 13, 14 and 15, the bristle elements 10 are at least partially freed from impurities picked up from the surface of the roller 02. This can, for example, be achieved or at least supported by scrapers, not shown, which are arranged in the respective cleaning chambers.

Beim in den Figuren gezeigten Ausführungsbeispiel weist jede Reinigungskammer 11, 12, 13, 14 und 15 einen Zulauf 16 für ein Reinigungsmittel zu Reinigung der Borstenelemente 10 auf. Als Reinigungsmittel kann dabei eine Reinigungsflüssigkeit, beispielsweise Wasser, gegebenenfalls auch unter Zusatz von Lösungsmitteln, Seifen, Laugen oder dergleichen, Verwendung finden. Durch diesen Zulauf 16 wird das Reinigungsmittel in die Reinigungskammern 11, 12, 13, 14 und 15 gespült, wobei die durch die Reinigungskammern geführten Borstenelemente 10 benetzt und von ihrer Schmutzfracht befreit werden.In the exemplary embodiment shown in the figures, each cleaning chamber 11, 12, 13, 14 and 15 has an inlet 16 for a cleaning agent for cleaning the bristle elements 10. A cleaning liquid, for example water, optionally also with the addition of solvents, soaps, alkalis or the like, can be used as the cleaning agent. The cleaning agent is flushed into the cleaning chambers 11, 12, 13, 14 and 15 through this inlet 16, the bristle elements 10 guided through the cleaning chambers being wetted and freed of their dirt load.

Weiter weist jede Reinigungskammer 11, 12, 13, 14 und 15 einen Ablauf 17 für das nach der Reinigung der Borstenelemente 10 verschmutzte Reinigungsmittel auf.Furthermore, each cleaning chamber 11, 12, 13, 14 and 15 has an outlet 17 for the cleaning agent soiled after cleaning the bristle elements 10.

Am Ende des Trums 07 und damit in Laufrichtung des Zahnriemens 03 hinter den Reinigungskammern 11, 12, 13, 14 und 15 ist eine weitere Kammer 18 angeordnet, die ebenfalls vom Zahnriemen 03 und den Borstenelementen 10 durchlaufen wird. In dieser Kammer 18, in die kein Reinigungsmittel zugeführt wird, erfolgt eine gezielte Entfeuchtung der Borstenelemente 10 bis auf einen in Abhängigkeit vom jeweiligen Anwendungsfall vorzugebenden Grad. Dabei kann diese Entfeuchtung beispielsweise durch ein nicht dargestelltes Abstreifelement, das mit den Borstenelementen 10 in Eingriff kommt, oder durch Einblasen von Druckluft oder dergleichen erfolgen. Das abgestreifte oder abgeblasene Reinigungsmittel wird durch einen Ablauf 19 aus der Kammer 18 abgeführt.At the end of the run 07 and thus in the running direction of the toothed belt 03 behind the cleaning chambers 11, 12, 13, 14 and 15, a further chamber 18 is arranged, which is likewise passed through by the toothed belt 03 and the bristle elements 10. In this chamber 18, into which no cleaning agent is supplied, the bristle elements 10 are dehumidified to a certain degree depending on the respective application. This dehumidification can take place, for example, by means of a stripping element, not shown, which comes into engagement with the bristle elements 10, or by blowing in compressed air or the like. The stripped or blown-off cleaning agent is discharged from the chamber 18 through an outlet 19.

Wie aus Fig. 1 ersichtlich, münden die Abläufe 17 der Reinigungskammern 11, 12, 13, 14 und 15 sowie der Ablauf 19 der Kammer 18 in einen gemeinsamen Sammelkanal 20. Der Sammelkanal 20 ist über eine Leitung 21 mit einem Sammelgefäß 22 verbunden, in welches das verschmutzte Reinigungsmittel geleitet wird.As can be seen from FIG. 1, the outlets 17 of the cleaning chambers 11, 12, 13, 14 and 15 and the outlet 19 of the chamber 18 open into a common collecting duct 20. The collecting duct 20 is connected to a collecting vessel 22 via a line 21, in which the dirty detergent is directed.

Das verschmutzte Reinigungsmittel wird im oder im Anschluß an das Sammelgefäß 22 durch ein Filterelement 23 geführt und dort von den Verunreinigungen gereinigt.The contaminated cleaning agent is passed through a filter element 23 in or subsequent to the collecting vessel 22 and is cleaned of the contaminants there.

Anschließend wird das so wiederaufbereitete und gegebenenfalls nachdosierte Reinigungsmittel in einem zweiten Sammelgefäß 24 gespeichert und von dort mittels einer Pumpe 25 und eine Leitung 26 wieder über die Zuläufe 16 in die Reinigungskammern 11, 12, 13, 14 und 15 gegeben. Insgesamt läßt sich daher ein im wesentlichen geschlossener Reinigungsmittelkreislauf realisieren.The cleaning agent which has been reprocessed in this way and optionally replenished is then stored in a second collecting vessel 24 and from there it is returned to the cleaning chambers 11, 12, 13, 14 and 15 via the inlets 16 by means of a pump 25 and a line 26. Overall, an essentially closed detergent circuit can therefore be implemented.

Wie insbesondere aus der Darstellung nach Fig. 2 ersichtlich ist, sind beim hier gezeigten Ausführungsbeispiel zwei Zahnriemen 03 und 27 bezogen auf die Umfangsrichtung der Walze 02 hintereinander, d. h. übereinander angeordnet. Dabei ist der zweite Zahnriemen 27 in gleicher Weise wie der erste Zahnriemen 03 über seine halbe Länge mit Borstenelementen 28 versehen. Der Zahnriemen 27 ist in grundsätzlich der gleichen Weise wie der Zahnriemen 03 über nicht dargestellte Riemenscheiben geführt, deren Mittelachsen mit den Mittelachsen 08 und 09 der Riemenscheiben 04 und 05 fluchten. Zumindest eine der Riemenscheiben des Zahnriemens 27 weist einen Antrieb auf, mit dem diese Riemenscheibe mit einem Drehmoment zum Antrieb des Zahnriemens 27 beaufschlagbar ist. Der Antrieb des Zahnriemens 03 und der Antrieb des Zahnriemens 27 sind dabei grundsätzlich unabhängig. Beim hier dargestellten Ausführungsbeispiel sind der Antrieb des Zahnriemens 03 und der Antrieb des Zahnriemens 27 gegenläufig, so daß auch die Drehrichtung der Riemenscheiben und damit der Zahnriemen 03 und 27 selbst gegenläufig sind. Die Drehrichtungen der Antriebe können umkehrbar sein.As can be seen in particular from the illustration according to FIG. 2, in the exemplary embodiment shown here two toothed belts 03 and 27 are connected one behind the other in relation to the circumferential direction of the roller 02; H. arranged one above the other. The second toothed belt 27 is provided with bristle elements 28 over its half length in the same way as the first toothed belt 03. The toothed belt 27 is guided in the same way as the toothed belt 03 over pulleys, not shown, whose central axes are aligned with the central axes 08 and 09 of the pulleys 04 and 05. At least one of the belt pulleys of the toothed belt 27 has a drive with which this belt pulley can be acted upon with a torque for driving the toothed belt 27. The drive of the toothed belt 03 and the drive of the toothed belt 27 are basically independent. In the embodiment shown here, the drive of the toothed belt 03 and the drive of the toothed belt 27 are in opposite directions, so that the direction of rotation of the belt pulleys and thus the toothed belt 03 and 27 itself are in opposite directions. The directions of rotation of the drives can be reversible.

Wie ebenfalls aus den Figuren ersichtlich ist, ist zwischen den Riemenscheiben 04 und 05 des Zahnriemens 03 und den nicht dargestellten Riemenscheiben des Zahnriemens 27 ein Führungselement 29 vorgesehen, das sich beim hier dargestellten Ausführungsbeispiel im wesentlichen über den gesamten Zwischenraum zwischen den jeweiligen Riemenscheiben erstreckt. Das Führungselement 29 weist beidseitig übereinander angeordnete nutartige Vertiefungen 30, 31 bzw. 32, 33 auf, in denen die jeweiligen Trume der Zahnriemen 03 und 27 geführt sind. Dabei erfolgt sowohl eine Führung senkrecht zur durch die Zahnriemenschlaufen gebildeten Hauptebenen als auch eine Abstützung der Zahnriemen 03 und 27 gegen den Nutgrund.As can also be seen from the figures, a guide element 29 is provided between the pulleys 04 and 05 of the toothed belt 03 and the not shown pulleys of the toothed belt 27, which extends in the embodiment shown here essentially over the entire space between the respective pulleys. The guide element 29 has groove-like depressions 30, 31 and 32, 33, one above the other, in which the respective strands of the toothed belts 03 and 27 are guided. This involves both Guide perpendicular to the main planes formed by the toothed belt loops and a support of the toothed belts 03 and 27 against the groove base.

Im Bereich des von der Walze wegweisenden Trums der Zahnriemen 03 und 27 ist am Führungselement 29 ein Bauteil 34 angeordnet, in dem die Reinigungskammern 11, 12, 13, 14 und 15 sowie die Kammer 18 für den oberen Zahnriemen 03 und, in grundsätzlich der gleichen Weise, die Reinigungskammern 35 und die Kammer für den unteren Zahnriemen 27 ausgebildet sind. Sämtliche Kammern münden dabei mit ihrem Ablauf 17 bzw. 19 (oberer Zahnriemen 03) und 36 (unterer Zahnriemen 27) in den gemeinsamen Sammelkanal 20, der ebenfalls unmittelbar im Bauteil 34 ausgebildet ist.In the region of the run of the toothed belt 03 and 27 pointing away from the roller, a component 34 is arranged on the guide element 29, in which the cleaning chambers 11, 12, 13, 14 and 15 and the chamber 18 for the upper toothed belt 03 and, in principle, the same Way, the cleaning chambers 35 and the chamber for the lower toothed belt 27 are formed. All chambers open with their outlet 17 or 19 (upper toothed belt 03) and 36 (lower toothed belt 27) into the common collecting duct 20, which is likewise formed directly in component 34.

Im Bauteil 34 sind weiter die Zuläufe 16 (oberer Zahnriemen 03) und 37 (unterer Zahnriemen 27) für den Zufluß von Reinigungsmittel die Reinigungskammer 11, 12, 13, 14 und 15 bzw. 35 angeordnet. Die Zuläufe 16 und 37 münden dabei in seitlich oben und unten am Bauteil 34 angesetzte Sammelleitungen 38 und 39, die über die Leitung 26 von Pumpe 25 mit Reinigungsmittel versorgt werden.In the component 34, the inlets 16 (upper toothed belt 03) and 37 (lower toothed belt 27) for the inflow of cleaning agent, the cleaning chamber 11, 12, 13, 14 and 15 and 35 are also arranged. Inlets 16 and 37 open into manifolds 38 and 39 attached laterally at the top and bottom of component 34, which are supplied with cleaning agent by pump 25 via line 26.

Im folgenden sei eine mögliche Betriebsweise der in den Figuren dargestellten erfindungsgemäßen Vorrichtung näher erläutert:A possible mode of operation of the device according to the invention shown in the figures is explained in more detail below:

Die zu reinigende Walze 02 weist an ihrer Oberfläche eine Platte 40 für Flexodruck auf, die nach einem bestimmungsgemäß beendeten Druckvorgang von Verunreinigungen, insbesondere Farbresten befreit werden soll.The roller 02 to be cleaned has a plate 40 for flexographic printing on its surface, which is to be freed of impurities, in particular ink residues, after a printing process which has ended as intended.

In der Ruheposition der Vorrichtung 1, wie sie insbesondere in Fig. 2 dargestellt ist, sind sämtliche Borstenelemente 10 und 28 am von der Walze 02 abgewandten Trum der Zahnriemen 03 und 27 angeordnet, so daß kein Eingriff an der Walze 02 bzw. an der flexographischen Platte 40 erfolgt. Gleichzeitig aber ist der Abstand der Vorrichtung 01 von der Walze 02 so gewählt, daß in der Arbeitsposition, d.h. das mit den Borstenelementen 10 versehene Trum des Zahnriemens weist nun zur Walze 02, die Borstenelemente mit der Walzenoberfläche in mechanischen Eingriff bzw. an der Walzenoberfläche zur Anlage gelangen können. Somit kann die erfindungsgemäße Vorrichtung 01 während des Druckvorgangs in unveränderter Position an der Walze verbleiben, so daß teure Rüstzeiten entfallen.In the rest position of the device 1, as is shown in particular in FIG. 2, all the bristle elements 10 and 28 are arranged on the run of the toothed belts 03 and 27 facing away from the roller 02, so that no engagement with the roller 02 or with the flexographic Plate 40 is done. At the same time, however, the distance of the device 01 from the roller 02 is selected so that in the working position, ie with the Bristle elements 10 provided strand of the toothed belt now points to the roller 02, the bristle elements with the roller surface in mechanical engagement or can come to rest on the roller surface. Thus, the device 01 according to the invention can remain in the unchanged position on the roller during the printing process, so that expensive makeready times are eliminated.

Der Einfachheit halber soll zunächst lediglich die Wirkung eines Zahnriemens 03 beschrieben werden.For the sake of simplicity, only the effect of a toothed belt 03 will be described first.

Soll nun nach Beendigung des Druckvorgangs eine Reinigung der Walze 02 bzw. der flexographischen Platte 40 erfolgen, werden zunächst die Reinigungskammern 11, 12, 13, 14 und 15 mit Reinigungsflüssigkeit gespült und dadurch die Borstenelemente 10 benetzt. Beim nachfolgenden Antrieb des Zahnriemens 03 wandern die Borstenelemente 10 durch die hintereinander angeordneten Kammern und werden nach dem Spülen mit Reinigungsmittel in den Reinigungskammern 11, 12, 13, 14 und 15 benetzten Borstenelemente 10 in der zweiten Kammer 19 gerade soweit entfeuchtet, daß zum einen beim Überstreichen der Walzenoberfläche ein unerwünschtes Austreten von Reinigungsmittel aus dem Spalt zwischen der Walze 02 und der Vorrichtung 01 weitgehend verhindert wird, zum anderen aber beim Überstreichen der an der Walzenoberfläche angeordneten Platte 40 mit den Borstenelementen 10 eine ausreichende Menge von Reinigungsmittel auf die Platte übertragen wird, um die durch den Reinigungsvorgang zu entfernende Farbe anzuweichen.If the roller 02 or the flexographic plate 40 is to be cleaned after the printing process has ended, the cleaning chambers 11, 12, 13, 14 and 15 are first rinsed with cleaning liquid and the bristle elements 10 are thereby wetted. In the subsequent drive of the toothed belt 03, the bristle elements 10 migrate through the chambers arranged one behind the other and after rinsing with detergent in the cleaning chambers 11, 12, 13, 14 and 15, the bristle elements 10 in the second chamber 19 are dehumidified to the extent that on the one hand An undesirable leakage of cleaning agent from the gap between the roller 02 and the device 01 is largely prevented by sweeping over the roller surface, but on the other hand a sufficient amount of cleaning agent is transferred to the plate when the plate 40 arranged on the roller surface is covered with the bristle elements 10. to soften the color to be removed by the cleaning process.

Bei der weiteren Bewegung des Zahnriemens 03 erfolgt also durch die Borstenelemente 10 zunächst sowohl eine Übertragung von Reinigungsmittel auf die zu reinigende Fläche als auch eine mechanisch abrasives Abtragen der Verschmutzung. Mit zunehmender Abgabe der Restfeuchte der Borstenelemente 10 auf die Oberfläche der Walze 02 bzw. der flexographischen Platte 40 sind die Borstenelemente 10 in der Lage, die Farbreste von der Walzenoberfläche aufzunehmen und über die Spülung in den Reinigungskammern 11, 12, 13, 14 und 15 zur Abscheidung abzugeben. Die Zykluszeit, d.h. insbesondere die Verweildauer und Menge des Reinigungsmittels auf der Walzenoberfläche, ist insbesondere durch die Anpassung der Drehzahl der Walze 02 und der Drehgeschwindigkeit des Zahnriemens, aber auch durch Einstellung des Restfeuchtegehalts der Borstenelemente 10 in der Kammer 18 in Abhängigkeit beispielsweise vom Verschmutzungsgrad in weiten Grenzen frei einstellbar.As the toothed belt 03 moves further, the bristle elements 10 initially transmit both cleaning agent to the surface to be cleaned and mechanically abrasive removal of the dirt. With increasing release of the residual moisture of the bristle elements 10 onto the surface of the roller 02 or the flexographic plate 40, the bristle elements 10 are able to take up the color residues from the roller surface and via the rinsing into the Dispense cleaning chambers 11, 12, 13, 14 and 15 for separation. The cycle time, that is to say in particular the dwell time and amount of the cleaning agent on the roller surface, is in particular due to the adaptation of the rotational speed of the roller 02 and the rotational speed of the toothed belt, but also by adjustment of the residual moisture content of the bristle elements 10 in the chamber 18 depending on, for example, the degree of contamination in wide limits freely adjustable.

Durch die Anordnung eines zweiten Zahnriemens 27, der in grundsätzlich der gleichen Weise wirkt, jedoch gegenläufig zum Zahnriemen 03 angetrieben ist, kann insbesondere die Reinigungsfläche vergrößert und dadurch die Reinigungszeit verkürzt werden. Aufgrund der gegenläufigen Bewegung der beiden Zahnriemen 03 und 27 unterliegen zudem die in Bewegungsrichtung der Zahnriemen 03 und 27 gegenüberliegenden Flanken der bestimmungsgemäßen Erhöhungen und/oder Vertiefungen der Walzenoberfläche einer gleichmäßigeren Reinigungswirkung, da "Schattenbereiche" weitestgehend verhindert werden.The arrangement of a second toothed belt 27, which acts in basically the same way, but is driven in the opposite direction to the toothed belt 03, in particular increases the cleaning area and thereby shortens the cleaning time. Due to the opposite movement of the two toothed belts 03 and 27, the flanks of the intended elevations and / or depressions of the roller surface opposite in the direction of movement of the toothed belts 03 and 27 are also subject to a more uniform cleaning effect, since "shadow areas" are largely prevented.

Die Vorrichtung 01 ist ferner mit einem Gehäuse 41 versehen, das zur Walze 02 hin offen ist. Die Kantenbereiche des Gehäuses 41 im Bereich beider Stirnseiten der Walze 02 weisen Spritzbleche 42 und 43 auf, die, in Abhängigkeit von der Drehrichtung der Zahnriemen 03 und 27, ein unkontrolliertes Abspritzen von Reinigungsmittel beim Austritt der Borstenelemente 10 aus der Kammer 18 bzw. von verschmutztem Reinigungsmittel beim Eintritt der Borstenelemente 10 in das Gehäuse 41 verhindern.The device 01 is also provided with a housing 41 which is open towards the roller 02. The edge areas of the housing 41 in the area of both end faces of the roller 02 have splash plates 42 and 43 which, depending on the direction of rotation of the toothed belts 03 and 27, cause uncontrolled spraying of cleaning agent when the bristle elements 10 emerge from the chamber 18 or contaminated Prevent cleaning agents when the bristle elements 10 enter the housing 41.
