An eine Rasterwalze 1 eines Kurzfarbwerkes ist eine insgesamt mit 2 bezeichnete Kammerrakeleinrichtung anstellbar. Die Kammerrakeleinrichtung 2 kann aus einer Farbwanne 3 mit einem etwa U-förmigen Profil bestehen, welche sich mit einer Länge l unterhalb und achsparallel zur Rasterwalze 1 erstreckt. Die Länge l der Farbwanne 3 kann ein Viertel der Gesamtlänge der Rasterwalze 1 betragen, so daß vier verschiedene Farbwannen 3 unter der Rasterwalze 1 angeordnet sein können. Jede Farbwanne 3 weist stirnseitige Schließbleche 4, 6 auf, welche das U-Profil beidseitig z. B. mittels Schrauben verschließen. Die Schließbleche 4; 6 sind mit ihrer der Rasterwalze 1 zugewandten Seite der Peripherie der Rasterwalze 1 angepaßt. An beiden Schließblechen 4; 6 sind in achsparalleler Richtung zur Rasterwalze 1 sowie ins Innere der Kammerrakeleinrichtung 2 weisende Achszapfen 7; 8 befestigt, auf welchen über Kugellager 9; 11 beidendig eine Walze, z. B. Gummiwalze 12 rotierbar gelagert ist. Die Gummiwalze 12 weist auf ihrem Mantel 15 Erhebungen 13 auf, die z. B. rhombenförmig ausgebildet sein können (in Fig. 2 ausschnittsweise dargestellt). Die Gummiwalze 12 ist in einem solchen Abstand a zur Rasterwalze 1 angeordnet, daß diese bei Drehung der Rasterwalze 1 durch Reibung angetrieben werden kann, wobei sich zwischen der Rasterwalze 1 sowie der Gummiwalze 12 ein auf die Rasterwalze 1 zu übertragender Film von Druckfarbe befindet. Die Gummiwalze 12 kann auch separat durch eine nichtdargestellte Antriebseinheit, z. B. einen Elektromotor, angetrieben werden. Am Boden 14 der Farbwanne 3, d. h. in einem geringen Abstand zu diesem sowie in einem Abstand b zum Mantel 15 der Gummiwalze 12 sind mehrere, z. ß. zwei in achsparalleler Richtung nebeneinander befindliche angetriebene Scheiben 17; 18 angeordnet, deren Antriebswellen 19; 21 rechtwinklig zur Rotationsachse 22 verlaufen und zu außerhalb der Kammerrakeleinrichtung 2 befindlichen, nichtdargestellten Antrieben führen können. Die Antriebe können z. B. außen am Boden 14 der Farbwanne 3 angeflanscht sein. Der Abstand b der Scheiben 17; 18 zur Gummiwalze 12 ist für jede Scheibe 17; 18 einzeln einstellbar. Es ist aber auch möglich, daß der Abstand b der Scheiben 17; 18 zur Gummiwalze 12 für beide Scheiben 17; 18 gemeinsam einstellbar ist. Die Kammerrakeleinrichtung 2 weist zwei in einem Abstand zueinander angeordnete, an die Gummiwalze 12 anstellbare federnde Rakelblätter - eine Arbeitsrakel 23 sowie eine Schließrakel 24 - auf, die sich in achsparalleler Richtung zur Rasterwalze 1 erstrecken und in leistenförmigen Haltern 26; 27 festgeklemmt sind. Die Halter 26; 27 für die Rakel 23; 24 sind beidendig formschlüssig mit den Schließblechen 4; 6 der Kammerrakeleinrichtung 2 verbunden.A chambered doctor blade device, designated as a whole by 2, can be placed on an anilox roller 1 of a short inking unit. The chamber doctor blade device 2 can consist of an ink tray 3 with an approximately U-shaped profile, which extends with a length l below and axially parallel to the anilox roller 1. The length l of the ink tray 3 can be a quarter of the total length of the anilox roller 1 amount, so that four different ink tanks 3 can be arranged under the anilox roller 1. Each paint tray 3 has end plates 4, 6, which the U-profile on both sides z. B. close with screws. The striking plates 4; 6 are adapted with their side facing the anilox roller 1 to the periphery of the anilox roller 1. On both striking plates 4; 6 are in the axis-parallel direction to the anilox roller 1 and inside the chamber doctor device 2 pointing axles 7; 8 attached, on which via ball bearings 9; 11 both ends of a roller, e.g. B. rubber roller 12 is rotatably mounted. The rubber roller 12 has on its jacket 15 elevations 13 which, for. B. can be rhomboidal (shown in detail in Fig. 2). The rubber roller 12 is arranged at such a distance a from the anilox roller 1 that it can be driven by friction when the anilox roller 1 rotates, with a film of printing ink to be transferred to the anilox roller 1 between the anilox roller 1 and the rubber roller 12. The rubber roller 12 can also be separately by a drive unit, not shown, for. B. an electric motor. At the bottom 14 of the ink pan 3, ie at a short distance from it and at a distance b from the jacket 15 of the rubber roller 12, several, for. ß. two driven disks 17 located next to one another in the axis-parallel direction; 18 arranged, the drive shafts 19; 21 run at right angles to the axis of rotation 22 and to outside of Chamber doctor device 2 located, not shown drives can lead. The drives can e.g. B. flanged outside on the bottom 14 of the ink pan 3. The distance b between the disks 17; 18 to the rubber roller 12 is for each disc 17; 18 individually adjustable. But it is also possible that the distance b of the disks 17; 18 to the rubber roller 12 for both disks 17; 18 is adjustable together. The chambered doctor device 2 has two resilient doctor blades - a working doctor blade 23 and a closing doctor blade 24 - which are arranged at a distance from one another and can be adjusted, which extend in the axis-parallel direction to the anilox roller 1 and in strip-shaped holders 26; 27 are clamped. The holder 26; 27 for the squeegee 23; 24 are form-fitting on both ends with the striking plates 4; 6 of the chamber doctor blade device 2 connected.

Nach einem weiteren Ausführungsbeispiel ist es möglich, statt einer oder mehrerer angetriebener Scheiben 17; 18 unterhalb und achsparallel zur Walze 12 eine zweite in einem Abstand b beabstandete nichtdargestellte Walze anzuordnen, welche sich mitläufig zur Walze 12, d. h. im Uhrzeigersinn (Fig. 1), dreht. Der Antrieb der zweiten Walze kann synchron zum Antrieb der Walze 12 erfolgen. Das Material sowie die Oberfläche der zweiten Walze kann so beschaffen sein, wie bei der Walze 12 ausgeführt. Die zweite Walze kann auch einen Stahlmantel aufweisen. Der Durchmesser der zweiten Walze kann vom Durchmesser der Walze 12 abweichen. Sollte die zweite Walze von der Walze 12 mittels Friktionsantrieb bewegt werden, so würde ein geringerer Durchmesser der zweiten Walze von Vorteil sein. Die Farbwanne 3 kann um einen Winkel Alpha verschwenkbar angeordnet sein.According to a further exemplary embodiment, it is possible, instead of one or more driven disks 17; 18 below and axially parallel to the roller 12 to arrange a second roller, not shown, spaced at a distance b, which rotates along with the roller 12, ie clockwise (FIG. 1). The second roller can be driven synchronously with the drive of the roller 12. The material as well as the surface of the second roller can be designed as described for the roller 12. The second roller can also have a steel jacket. The diameter of the second roller can vary from the diameter of the Roller 12 deviate. Should the second roller be moved by the roller 12 by means of a friction drive, a smaller diameter of the second roller would be advantageous. The ink tray 3 can be arranged so as to be pivotable by an angle alpha.

Der Winkel Alpha kann zwischen Null und 45° liegen. Eine Füllhöhe h der Druckfarbe 20 kann zwischen einem Viertel bis zur Hälfte des Durchmessers der Walze 12 betragen.The angle alpha can be between zero and 45 °. A filling height h of the printing ink 20 can be between a quarter to half the diameter of the roller 12.
