   Gegenstand der Erfindung ist ein mit der Rakel verbundenes Farbwerk für Tiefdruck-   Rotationsmaschinen, das   zur Erzeugung eines saubern Druckes bei wirtschaftlichem Farbverbrauche mitwirkt und zugleich ein bequemes Abnehmen der Teile ermöglicht. Bei dieser Neuerung kann der unterhalb und in unmittelbarer Berührung mit der Rakel angeordnete   Farbbehälter   als im Querschnitt dreieckiger Hohlkörper ausgebildet und in seiner Längsrichtung durch zwei   Abschlussplatten   begrenzt werden, wovon eine oder auch beide den Anschluss an

 Es ist Fig. l ein Querschnitt der neuen Vorrichtung, Fig. 2 ein Aufriss und Fig. 3 ein Seitenriss. 



   In Fig. 1 und 2 bezeichnet 0 den   Tiefdruck-Formzylinder,   die Rakel in beispielsweise horizontaler Stellung, 2 und 3 die zugehörigen Klemmschienen, 4 die erste in geringer Neigung zum Rakelblatt befindliche federnde Wand, 5 die zweite mehr tangential zur Oberfläche des

   Die Wirkungsweise des   neuen Rakelfarbwerks ist folgende :   In der Ruhestellung drückt die Rakel 1 infolge ihrer Federkraft die federnde Wand 4 fest auf die Kante der Wand 5, wodurch   ein dichter Abschluss des Farbkastens erzielt wird. Sobald die Rakel in Arbeitsstellung gebracht

 EMI1.1
 



   The subject matter of the invention is an inking unit for rotogravure printing presses connected to the doctor blade, which contributes to the production of a clean print with economical ink consumption and at the same time enables the parts to be removed easily. With this innovation, the ink container arranged below and in direct contact with the squeegee can be designed as a hollow body with a triangular cross-section and delimited in its longitudinal direction by two end plates, one or both of which are connected to
 EMI1.2
 FIG. 1 is a cross section of the new device, FIG. 2 is an elevation and FIG. 3 is a side elevation.



   In Fig. 1 and 2, 0 denotes the gravure forme cylinder, the squeegee in a horizontal position, for example, 2 and 3 the associated clamping rails, 4 the first resilient wall located at a slight incline to the squeegee blade, 5 the second more tangential to the surface of the
 EMI1.3
 



   The mode of operation of the new squeegee inking unit is as follows: In the rest position, the squeegee 1 presses the resilient wall 4 firmly on the edge of the wall 5 due to its spring force, whereby a tight seal of the ink fountain is achieved. As soon as the squeegee is brought into working position
