The intermediate plate (6) can be locked in its position of rest retracted from the duct roller by a locking rod (21), the end (21b) of which engages in a notch in the intermediate plate. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Farbwerk für eine Druckmaschine, mit einer Duktorwalze und einem Farbkasten, welcher einen Boden und wenigstens eine Trennwand aufweist, wobei der Boden wenigstens in dem der Duktorwalze benachbarten Bereich durch eine Rakel gebildet wird, deren Vorderkante an der Duktorwalze anliegt.The invention relates to an inking unit for a printing press, having a duct roller and an ink fountain, which has a bottom and at least one partition, the bottom being formed at least in the region adjacent to the duct roller by a doctor blade, the front edge of which abuts the duct roller.

Farbkästen mit Trennwänden dienen zur Aufnahme unterschiedlicher Farben in den durch eine Trennwand unterteilten Abschnitten und werden immer dann eingesetzt, wenn die Duktorwalze und damit die einzufärbende Druckplatte gleichzeitig mit zwei oder mehreren, unmittelbar nebeneinander liegenden unterschiedlichen Farben eingefärbt werden soll, wie es beispielsweise beim sogenannten Iris-Druck üblich ist.Ink boxes with dividing walls serve to hold different colors in the sections divided by a dividing wall and are always used when the duct roller and thus the printing plate to be inked are to be colored simultaneously with two or more different colors lying directly next to each other, such as the so-called Iris - Printing is common.

Bei einem aus der US-PS 2 525 363 bekannten Farbwerk besteht die Trennwand des Farbkastens aus drei fest zusammengenieteten Platten, von denen die beiden äusseren Platten mit ihren unteren und ihren vorderen, der Duktorwalze zugewandten Rändern die dazwischenliegende mittlere Platte derart überragen, dass zwischen den erwähnten Rändern der beiden äusseren Platten eine Umfangsnut gebildet wird. In dieser Umfangsnut ist ein biegsamer, die Ränder der beiden äusseren Platten überragender Dichtungsstreifen, beispielsweise aus Filz, angeordnet, der sich mit dem Boden des Farbkastens und, an seinem konkaven, dem Umfang der Duktorwalze angepassten vorderen Rand, mit dieser Duktorwalze in Berührung befindet. Die gesamte Trennwand ist mittels Befestigungsschrauben an einer den Farbkasten überragenden Trägerstange aufgehängt, die an der Rückwand des Farbkastens befestigt ist. Um die Trennwand zu justieren, sind in der Trägerstange Justierschrauben vorgesehen, welche auf den oberen Rand der Trennwand wirken und diese, solange ihre Befestigungsschrauben noch nicht angezogen sind, zu verstellen erlauben. Ausserdem sind zwischen den beiden äusseren Platten, in einer dafür vorgesehenen Kammer, ein verschiebbarer Gummikörper, welcher an dem gekrümmten, die Duktorwalze berührenden Abschnitt des Dichtungsstreifens anliegt, und ein mit diesem Gummikörper zusammenwirkender Keil vorgesehen, der in Abwärtsrichtung durch eine Schraube beaufschlagt wird. Die Anordnung ist so getroffen, dass der durch die Schraube nach unten gedrückte Keil den Gummikörper nach vorn verschiebt, wodurch der erwähnte Abschnitt des Dichtungsstreifens gegen die Duktorwalze gepresst wird, um einen dichten Kontakt mit dieser zu ermöglichen.In an inking unit known from US Pat. No. 2,525,363, the partition of the ink fountain consists of three firmly riveted plates, of which the two outer plates, with their lower and their front edges facing the ductor roller, project beyond the intermediate central plate in such a way that between the mentioned edges of the two outer plates a circumferential groove is formed. Arranged in this circumferential groove is a flexible sealing strip, for example made of felt, projecting beyond the edges of the two outer plates, which is in contact with the bottom of the ink fountain and, on its concave front edge, which is adapted to the circumference of the duct roller, with this duct roller. The entire partition is suspended by means of fastening screws on a support rod which projects beyond the ink fountain and is fastened to the rear wall of the ink fountain. In order to adjust the partition, adjusting screws are provided in the support bar, which are on the upper edge of the partition and allow it to be adjusted as long as its fastening screws are not tightened. In addition, between the two outer plates, in a chamber provided for this purpose, there is a displaceable rubber body which bears on the curved section of the sealing strip which contacts the ductor roller, and a wedge which interacts with this rubber body and is acted upon in the downward direction by a screw. The arrangement is such that the wedge pushed down by the screw pushes the rubber body forward, whereby the mentioned section of the sealing strip is pressed against the ductor roller in order to enable a tight contact with it.

Dieses bekannte Farbwerk ist verhältnismässig kompliziert aufgebaut, und die Justierung der Trennwand sowie die Wartung und Reinigung des Farbkastens sind schwierig und zeitraubend.This known inking unit has a relatively complicated structure, and the adjustment of the partition as well as the maintenance and cleaning of the ink fountain are difficult and time-consuming.

Bei einem in der US-PS 2 301 535 beschriebenen Farbkasten mit Trennwand besteht diese aus zwei im Abstand voneinander liegenden Platten, zwischen denen ein nachgiebiges Dichtungsmaterial in Form eines dicken Streifens, beispielsweise aus Filz oder Gummi, angeordnet ist und über die Plattenränder vorsteht. Mehrere, zwischen den Platten befestigte Blöcke mit Gewindeöffnungen dienen zur Aufnahme von Schrauben, welche die Innenränder des Dichtungsmaterials, unter Zwischenlage von Druckstreifen, beaufschlagen und mit denen das Dichtungsmaterial einerseits gegen den Boden des Farbkastens und andererseits gegen die Duktorwalze gedrückt werden kann.In a paint box with partition described in US Pat. No. 2,301,535, it consists of two spaced-apart plates, between which a resilient sealing material in the form of a thick strip, for example made of felt or rubber, is arranged and protrudes beyond the plate edges. Several blocks with threaded openings fastened between the plates serve to hold screws which act on the inner edges of the sealing material, with the interposition of pressure strips, and with which the sealing material can be pressed on the one hand against the bottom of the ink fountain and on the other hand against the duct roller.

Der Erfindung liegt die Aufgabe zugrunde, ein Farbwerk mit einem wenigstens eine Trennwand aufweisenden Farbkasten zu schaffen, bei welchem mit einfachen Mitteln eine vollkommene Dichtheit zwischen Trennwand und Duktorwalze einerseits und Boden andererseits gewährleistet ist, welcher einfach gewartet und gehandhabt werden kann und dessen Trennwand leicht zu justieren ist.The invention has for its object to provide an inking unit with an ink fountain having at least one partition, in which, with simple means, a perfect seal between the partition and duct roller on the one hand and floor on the other hand, which is easy to maintain and handle and whose partition is easy to adjust.

Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of claim 1.

Die Erfindung bietet den Vorteil, dass die durch Dichtungsstreifen am unteren Rand der äusseren Metallplatten der Trennwand gewährleistete Abdichtung zwischen Trennwand und Boden des Farbkastens völlig unabhängig von der zwischen Trennwand und Duktorwalze bestehenden Abdichtung ist, welche durch die Zwischenplatte aus Kunststoff sichergestellt wird; diese relativ zu den Metallplatten verschiebbare Zwischenplatte ragt vorn zwischen den Metallplatten, die die Duktorwalze nicht berühren, heraus und wird durch die Anpresselemente selbständig in Bezug auf die Duktorwalze justiert.The invention offers the advantage that the seal between the partition and the bottom of the ink fountain, which is ensured by sealing strips on the lower edge of the outer metal plates of the partition, is completely independent of the seal existing between the partition and the duct roller, which is ensured by the intermediate plate made of plastic; this intermediate plate, which is displaceable relative to the metal plates, protrudes at the front between the metal plates which do not touch the duct roller and is automatically adjusted with respect to the duct roller by the pressing elements.

Gemäss einer bevorzugten Ausführungsform der Erfindung wird die Zwischenplatte zwischen den beiden Metallplatten mit satter Reibung gehalten und mittels einer metallischen Stange geführt, die an den beiden Metallplatten befestigt ist und ein Langloch in der Zwischenplatte durchsetzt. Vorteilhafterweise bestehen die auf die Zwischenplatte wirkenden Anpresselemente aus wenigstens zwei Federn, welche zwei in unterschiedlichen Höhen liegende, vertikale Abschnitte des hinteren Randes der Zwischenplatte beaufschlagen.According to a preferred embodiment of the invention, the intermediate plate is held between the two metal plates with a high degree of friction and is guided by means of a metallic rod which is fastened to the two metal plates and penetrates an elongated hole in the intermediate plate. Advantageously, the pressing elements acting on the intermediate plate consist of at least two springs which act on two vertical sections of the rear edge of the intermediate plate lying at different heights.

Ferner ist der obere Rand der Zwischenplatte vorteilhafterweise mit einer Kerbe versehen, über der eine axial verschiebbare Verriegelungsstange vorgesehen ist, welche in ihrer unteren Lage zwecks Verriegelung der Zwischenplatte in ihrer von der Duktorwalze zurückgezogenen Stellung in die Kerbe eingreift und in ihrer angehobenen Lage die Zwischenplatte freigibt.Furthermore, the upper edge of the intermediate plate is advantageously provided with a notch, above which an axially displaceable locking rod is provided, which in its lower position engages in the notch in its position withdrawn from the duct roller and into the intermediate plate releases their raised position.

Zweckmässigerweise haben die beiden Metallplatten geneigte Vorderränder, über welche der vordere Teil der Zwischenplatte vorsteht. Im oberen Bereich der Trennwand wird vorzugsweise die Dichtheit zwischen den Metallplatten und der Zwischenplatte durch Dichtungsstreifen gewährleistet, die in Nuten eingesetzt sind, welche längs der geneigten Vorderränder der Metallplatten auf deren Innenseite angebracht sind.The two metal plates expediently have inclined front edges, over which the front part of the intermediate plate protrudes. In the upper region of the partition, the tightness between the metal plates and the intermediate plate is preferably ensured by sealing strips which are inserted in grooves which are provided along the inclined front edges of the metal plates on the inside thereof.

Weitere zweckmässige Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Further expedient refinements of the invention result from the dependent claims.

In order to illustrate an application of the inking units, stencil rollers C assigned to them are shown, which ink the intaglio printing plates, not shown, on the plate cylinder D of an intaglio printing machine.

Die Figuren 2 bis 5 zeigen die erfindungsgemässe Trennwand, die am Boden 2 des Farbkastens befestigt wird, um diesen mit zwei unterschiedlichen Farben verwenden zu können. Diese Trennwand besteht aus zwei, die Duktorwalze 1 nicht berührenden Metallplatten 4, 5, die näherungsweise die gleiche Form haben und, mit Abstand gegenüberliegend, miteinander befestigt sind, und aus einer zwischen diesen Metallplatten 4, 5 mit satter Reibung angeordneten Zwischenplatte 6 aus Kunststoff, welche vorn die Metallplatten 4, 5 überragt und relativ zu diesen in begrenztem Umfang verschoben und gekippt werden kann, wie das nachstehend erläutert wird. Die beiden Metallplatten 4, 5 haben einen geneigten Vorderrand 4a, 5a, der in ein leicht gebogenes Ende ausläuft und den unteren Rand 4b, 5b der Metallplatten 4, 5 unter einem spitzen Winkel schneidet.Figures 2 to 5 show the partition according to the invention, which is attached to the bottom 2 of the ink fountain so that it can be used with two different colors. This partition consists of two metal plates 4, 5 which do not touch the duct roller 1, which have approximately the same shape and are attached to one another at a distance from each other, and an intermediate plate 6 made of plastic arranged between these metal plates 4, 5 with a high degree of friction, which projects above the metal plates 4, 5 and can be displaced and tilted to a limited extent relative to these, as will be explained below. The two metal plates 4, 5 have an inclined front edge 4a, 5a, which ends in a slightly curved end and the lower edge 4b, 5b of the metal plates 4, 5 cuts at an acute angle.

Die in den Figuren 6 und 7 getrennt dargestellte Zwischenplatte 6 hat eine Vorderkante 6a in Form eines Kreisbogens, dessen Krümmungsradius dem des Umfangs der Duktorwalze 1 entspricht, an welcher sie genau anliegt. Diese Vorderkante 6a endet nach oben in zwei abgeschrägten Facetten 6f (Figur 3). Der hintere Rand der Zwischenplatte 6 ist stufenförmig unter Bildung zweier vertikaler Abschnitte 6b, 6c ausgebildet. Die Zwischenplatte 6 hat in ihrem vorderen Bereich ein Langloch 6e (Figur 6), das zu ihrer Führung dient, im hinteren Bereich ein Loch 6g zur Befestigung einer Positionierungsstange 18 und in der die beiden vertikalen Abschnitte 6b und 6c verbindenden horizontalen Wand eine Kerbe 6d.The intermediate plate 6 shown separately in FIGS. 6 and 7 has a front edge 6a in the form of a circular arc, the radius of curvature of which corresponds to that of the circumference of the duct roller 1, against which it lies precisely. This front edge 6a ends at the top in two bevelled facets 6f (FIG. 3). The rear edge of the intermediate plate 6 is stepped to form two vertical sections 6b, 6c. The intermediate plate 6 has an elongated hole 6e (FIG. 6) in its front area, which is used for guiding it, a hole 6g in the rear area for fastening a positioning rod 18 and a notch 6d in the horizontal wall connecting the two vertical sections 6b and 6c.

Zur Befestigung der beiden Metallplatten 4 und 5 miteinander dient im oberen Bereich ein erstes Befestigungsteil 7 in Form eines Winkelstücks, das mit einer ein Abstandsstück bildenden Rippe 7a versehen ist, die zwischen die beiden Metallplatten 4, 5 eingreift, wobei die Verbindung mittels dreier Befestigungsschrauben 15 erfolgt, welche die Rippe 7a und die Metallplatten 4, 5 durchsetzen. Im unteren, hinteren Bereich dient zur Befestigung ein zweites Befestigungsteil 8, das ebenfalls mit einer ein Abstandstück bildenden Rippe 8a versehen ist, die dieselbe Dicke wie das erste Befestigungsteil 7 hat und ebenfalls zwischen die beiden Metallwände 4, 5 eingreift; die Verbindung erfolgt mit zwei Befestigungsschrauben 16, welche die Rippe 8a und die Metallplatten 4, 5 durchsetzen. Die Metallplatte 4 hat an dieser Stelle eine Verdickung 4c, und das Befestigungsteil 8 ist ausserdem an der Metallplatte 4 mittels einer Schraube 27a befestigt, die ein Loch 27 in diesem Befestigungsteil 8 durchsetzt und in die Verdickung 4c hineinragt, wo sie angeschraubt ist (Figur 5).To fasten the two metal plates 4 and 5 to one another, a first fastening part 7 in the form of an angle piece is used in the upper region, which is provided with a rib 7a forming a spacer, which engages between the two metal plates 4, 5, the connection being made by means of three fastening screws 15 takes place, which penetrate the rib 7a and the metal plates 4, 5. In the lower, rear area, a second fastening part 8 is used for fastening, which is also provided with a rib 8a forming a spacer, which has the same thickness as the first fastening part 7 and also engages between the two metal walls 4, 5; the connection is made with two fastening screws 16 which penetrate the rib 8a and the metal plates 4, 5. The metal plate 4 has a thickening 4c at this point, and the fastening part 8 is also fastened to the metal plate 4 by means of a screw 27a which passes through a hole 27 in this fastening part 8 and in the thickening 4c protrudes where it is screwed (Figure 5).

Die Metallplatten 4, 5 sind so miteinander verbunden, dass die Zwischenplatte 6 mit satter Reibung zwischen diesen Metallplatten 4 und 5 verschiebbar ist. Die Führung der Zwischenplatte 6 zwischen den Metallplatten 4 und 5 erfolgt mittels einer zwischen diesen befestigten metallischen Stange 17, welche das Langloch 6e in dieser Zwischenplatte 6 durchsetzt.The metal plates 4, 5 are connected to one another in such a way that the intermediate plate 6 can be displaced with a firm friction between these metal plates 4 and 5. The intermediate plate 6 is guided between the metal plates 4 and 5 by means of a metallic rod 17 fastened between them, which passes through the elongated hole 6e in this intermediate plate 6.

Um einen dichten Kontakt zwischen der Vorderkante 6a der Zwischenplatte 6 und dem Umfang der Duktorwalze 1 zu erzielen, sind Anpresselemente vorgesehen, die in zwei verschiedenen Höhen auf den hinteren Rand der Zwischenplatte 6 wirken, um diese in ihre in Figur 2 strichpunktiert dargestellte Arbeitsstellung 6'a zu bringen. Diese Anpresselemente bestehen aus einer ersten mit einer Feder 10 versehenen Teleskopstange 9, die sich mit ihrem Kopf 9a am vertikalen Abschnitt 6b der Zwischenplatte 6 abstützt. Die Teleskopstange 9 wird am vertikalen Schenkel des Befestigungsteils 7 durch eine hohle Schraube 11 mit einer Gegenmutter 11a gehalten. Diese Teleskopstange 9 kann in der hohlen Schraube 11 gleiten und ist von der Feder 10 umgeben, die sich vorn am erwähnten Kopf 9a der Teleskopstange 9 und hinten an einem Federteller abstützt, der sich am Ende der Schraube 11 befindet. Durch die Stellung dieser Schraube 11 wird die Feder 10 komprimiert, um die zum sicheren Anpressen der Vorderkante 6a gegen die Duktorwalze 1 erforderliche Kraft zu erzeugen und damit eine gute Dichtheit zu erhalten. In der in Figur 2 mit vollen Linien dargestellten rückgezogenen Stellung greift die Teleskopstange 9 in die hohle Schraube 11 ein.In order to achieve a tight contact between the front edge 6a of the intermediate plate 6 and the circumference of the duct roller 1, pressing elements are provided which act on the rear edge of the intermediate plate 6 at two different heights in order to move it into the working position 6 'shown in broken lines in FIG. to bring a. These pressing elements consist of a first telescopic rod 9 provided with a spring 10, which is supported with its head 9a on the vertical section 6b of the intermediate plate 6. The telescopic rod 9 is held on the vertical leg of the fastening part 7 by a hollow screw 11 with a lock nut 11a. This telescopic rod 9 can slide in the hollow screw 11 and is surrounded by the spring 10, which is supported at the front on the mentioned head 9a of the telescopic rod 9 and at the rear on a spring plate which is located at the end of the screw 11. The position of this screw 11 compresses the spring 10 in order to generate the force required for securely pressing the front edge 6a against the duct roller 1 and thus to maintain a good seal. In the retracted position shown in FIG. 2 with full lines, the telescopic rod 9 engages in the hollow screw 11.

Eine zweite, mit einer Feder 13 versehene Teleskopstange 12 wird am zweiten Befestigungsteil 8 mit Hilfe einer hohlen Schraube 14 mit Gegenmutter 14a gehalten und drückt die Zwischenplatte 6 ebenfalls nach vorn in die Arbeitsstellung, wobei sich diese Teleskopstange 12 unter der Wirkung der Feder 13 gegen den vertikalen Abschnitt 6c der Zwischenplatte 6 abstützt. An der Stelle, wo die Enden der Teleskopstange 9 bzw. 12 angreifen, ist an der Zwischenplatte 6 vorzugsweise je ein metallischer Anschlag in U-Form vorgesehen, nämlich ein am vertikalen Abschnitt 6b befestigter Anschlag 28 bzw. ein am hinteren vertikalen Abschnitt 6c befestigter Anschlag 29.A second, provided with a spring 13 telescopic rod 12 is held on the second fastening part 8 by means of a hollow screw 14 with lock nut 14a and also presses the intermediate plate 6 forward into the working position, this telescopic rod 12 against the action of the spring 13 supports vertical section 6c of the intermediate plate 6. At the point where the ends of the telescopic rod 9 or 12 engage, a metallic stop in U-shape is preferably provided on the intermediate plate 6, namely a stop 28 fastened to the vertical section 6b or a stop fastened to the rear vertical section 6c 29.

Die Positionierungsstange 18, die im Loch 6g der Zwischenplatte 6 befestigt ist, durchquert ein in der Metallplatte 4 vorgesehenes Langloch 20; das Ende dieser Positionierungsstange 18 steht über der Trennwand vor und weist einen Griff 19 auf, mit dem die Zwischenplatte 6 manuell zurückgezogen und im Abstand von der Duktorwalze 1 ausser Betrieb gesetzt werden kann. Da der Boden 2 des Farbkastens in der Arbeitsstellung, wie sie in Figur 1 gezeigt ist, eine geneigte Lage hat, ist der Griff 19 wohlgemerkt nicht in die Farbe eingetaucht, deren Niveau sich unter diesem Griff 19 befindet. Es sind ausserdem Mittel zur Verriegelung der Zwischenplatte 6 in ihrer zurückgezogenen Stellung vorgesehen; diese Mittel bestehen aus einer Verriegelungsstange 21, die axial verschiebbar im horizontalen Abschnitt des Befestigungsteils 7 montiert und mit einem Kopf 21a versehen ist; ihr Ende 21b greift in die Kerbe 6d der Zwischenplatte 6 ein, um diese zu verriegeln, wenn sie sich in ihrer zurückgezogenen Stellung befindet. Der zwischen dem Kopf 21a und dem Befestigungsteil 7 befindliche Abschnitt der Verriegelungsstange 21 ist von einer Rückstellfeder 22 umgeben, welche die Verriegelungsstange 21 normalerweise in ihrer in Figur 2 strichpunktiert dargestellten angehobenen Stellung 21' hält.The positioning rod 18, which is fastened in the hole 6g of the intermediate plate 6, passes through an elongated hole 20 provided in the metal plate 4; the end of this positioning rod 18 protrudes above the partition and has a handle 19 with which the intermediate plate 6 can be manually withdrawn and put out of operation at a distance from the duct roller 1. Since the bottom 2 of the ink fountain in the working position, as shown in FIG. 1, has an inclined position, it should be noted that the handle 19 is not immersed in the paint, the level of which is below this handle 19. Means are also provided for locking the intermediate plate 6 in its retracted position; these means consist of a locking rod 21 which is mounted axially displaceably in the horizontal section of the fastening part 7 and is provided with a head 21a; its end 21b engages the notch 6d of the intermediate plate 6 to lock it when it is in its retracted position. The section of the locking rod 21 located between the head 21a and the fastening part 7 is surrounded by a return spring 22, which normally holds the locking bar 21 in its raised position 21 'shown in phantom in FIG. 2.

Die Dichtheit zwischen der Trennwand und dem Boden 2 des Farbkastens wird durch Dichtungsstreifen 25, 26 gewährleistet, die in Nuten eingesetzt sind, welche an den unteren Rändern der Metallplatten 4 und 5, parallel zu diesen Rändern, angebracht sind.The tightness between the partition and the bottom 2 of the ink fountain is ensured by sealing strips 25, 26 which are inserted in grooves which are attached to the lower edges of the metal plates 4 and 5, parallel to these edges.

Die Dichtheit zwischen der Zwischenplatte 6 und den Metallplatten 4 und 5 wird im oberen Bereich der Trennwand ebenfalls durch Dichtungsstreifen 23, 24 erreicht, die in Nuten eingesetzt sind, welche auf der Innenfläche der Metallplatten 4 und 5 längs ihrer geneigten Vorderränder 4a bzw. 5a angebracht sind.The tightness between the intermediate plate 6 and the metal plates 4 and 5 is also achieved in the upper region of the partition by sealing strips 23, 24 which are inserted in grooves which are provided on the inner surface of the metal plates 4 and 5 along their inclined front edges 4a and 5a are.

Die Trennwand ist ausserdem mit Mitteln zur Befestigung am Boden 2 des Farbkastens bzw. am Träger 2a versehen, die teilweise strichpunktiert nur in Figur 2 gezeigt sind. Diese Mittel bestehen aus einer Schraube 30, die ein Langloch 8b (Figur 5) durchsetzt, das in dem die Basis der Trennwand überragenden Abschnitt des Befestigungsteils 8 vorgesehen ist; diese Schraube 30 ist in den Träger 2a eingeschraubt. Die grosse Achse des Langlochs 8b ist parallel zum Boden 2.The partition is also provided with means for fastening to the bottom 2 of the ink fountain or to the carrier 2a, which are shown only partially in broken lines in FIG. 2. These means consist of a screw 30 which passes through an elongated hole 8b (FIG. 5) which is provided in the section of the fastening part 8 which projects beyond the base of the partition wall; this screw 30 is screwed into the carrier 2a. The large axis of the elongated hole 8b is parallel to the bottom 2.

Um die Trennwand in ihre in Figur 2 strichpunktiert dargestellte Arbeitsstellung 6'a zu bringen, zieht der Bedienende den Kopf 21a der Verriegelungsstange 21 nach oben in die angehobene Stellung 21', wodurch diese Verriegelungsstange 21 aus der Kerbe 6d austritt. Die Zwischenplatte 6 wird nunmehr unter der Wirkung der Federn 10 und 13 durch die Teleskopstangen 9 und 12 nach vorn in ihre Arbeitsstellung 6'a gestossen, in der die gebogene Vorderkante 6a am Umfang der Duktorwalze 1 anliegt; die Teleskopstange 9 nimmt dann ihre Arbeitsstellung 9' ein.In order to bring the dividing wall into its working position 6'a shown in dash-dotted lines in FIG. 2, the operator pulls the head 21a of the locking rod 21 upwards into the raised position 21 ', as a result of which this locking rod 21 emerges from the notch 6d. The intermediate plate 6 is now pushed under the action of the springs 10 and 13 by the telescopic rods 9 and 12 forward into its working position 6'a, in which the curved front edge 6a abuts the circumference of the duct roller 1; the telescopic rod 9 then assumes its working position 9 '.

Durch die beiden Anpresselemente, nämlich die Federn 10 und 13, wird erreicht, dass der auf die Zwischenplatte 6 ausgeübte Druck eine vollkommene Anlage dieser Zwischenplatte 6 am Umfang der Duktorwalze 1 garantiert und dass die dadurch erzeugte Dichtheit selbst dann aufrechterhalten bleibt, wenn der Umfang der Duktorwalze 1 etwas abgenutzt wird. Unabhängig von dieser Massnahme wird die Dichtheit der Trennwand mit dem Boden 2 durch die Dichtungsstreifen 25, 26 der Metallplatten 4 und 5 erreicht. Wenn daher im Laufe des Betriebs die Zwischenplatte 6 infolge einer leichten Veränderung des Umfangs der Duktorwalze 1 eine kleine Verschiebung erfährt, beeinflusst das die Dichtheit der Trennwand mit dem Boden in keiner Weise.The two pressing elements, namely the springs 10 and 13, ensure that the pressure exerted on the intermediate plate 6 guarantees that this intermediate plate 6 is in perfect contact with the circumference of the duct roller 1 and that the tightness produced thereby is maintained even if the circumference of the Duct roller 1 is somewhat worn. Regardless of this measure, the tightness of the partition with the bottom 2 is achieved by the sealing strips 25, 26 of the metal plates 4 and 5. Therefore, if the intermediate plate 6 undergoes a small shift during operation as a result of a slight change in the circumference of the duct roller 1, this in no way influences the tightness of the partition wall with the floor.

Die anderen Dichtungsstreifen 23 und 24 verhindern, dass Farbe von oben nach unten zwischen die Metallplatten 4 und 5 eindringen kann. Der obere Bereich der Vorderkante 6a der Zwischenplatte 6 mit seinen beiden abgeschrägten Facetten 6f erlaubt es, dass die Farbe, die auf dem Umfang der sich im Sinne des Pfeils in Figur 1 drehenden Duktorwalze 1 nach deren Kontakt mit der Schablonenwalze C verblieben ist, gut getrennt wird und auf die beiden Seiten der Zwischenplatte 6 gelangt.The other sealing strips 23 and 24 prevent paint from penetrating between the metal plates 4 and 5 from top to bottom. The upper region of the front edge 6a of the intermediate plate 6 with its two beveled facets 6f allows the ink which remained on the circumference of the duct roller 1 rotating in the direction of the arrow in FIG. 1 after its contact with the stencil roller C to be separated well is and reaches the two sides of the intermediate plate 6.

Bei der Ausserbetriebsetzung des Farbwerks oder bei seiner Demontage zieht der Bedienende den Griff 19 nach hinten, wodurch die Zwischenplatte 6 gegen die Wirkung der Federn 10 und 13 zurückgezogen wird, und nachdem sie ihre zurückgezogene Stellung (Figur 2) erreicht hat, stösst er die Verriegelungsstange 21 gegen die Wirkung der Rückstellfeder 22 nach unten, bis ihr Ende 21b in die Kerbe 6d eingreift und auf diese Weise die Zwischenplatte 6 in ihrer zurückgezogenen Stellung verriegelt. In dieser Stellung bewirkt die von den stark zusammengedrückten Federn 10 und 13 auf die Zwischenplatte 6 ausgeübte Kraft, dass die Verriegelungsstange 21, deren unterer Bereich sich in der Kerbe 6d befindet, durch Reibung in dieser Kerbe gegen die Wirkung der Rückstellfeder 22 gehalten wird, die somit keine Wirkung ausüben kann.When the inking unit is taken out of service or disassembled, the operator pulls the handle 19 backwards, whereby the intermediate plate 6 is withdrawn against the action of the springs 10 and 13, and after it has reached its retracted position (FIG. 2), it pushes the locking rod 21 against the action of the return spring 22 down until its end 21b engages in the notch 6d and in this way locks the intermediate plate 6 in its retracted position. In this position, the strongly compressed springs 10 and 13 on the Intermediate plate 6 exerted force that the locking rod 21, the lower region of which is located in the notch 6d, is held by friction in this notch against the action of the return spring 22, which can therefore have no effect.

Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt, sondern schliesst zahlreiche Ausführungsvarianten, insbesondere anders ausgebildete Anpress- und Verriegelungselemente, ein.The invention is not limited to the exemplary embodiment described, but rather includes numerous design variants, in particular differently designed pressing and locking elements.
