ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an inking unit for inking a printing or formed cylinder of a rotogravure printing press. The inking unit includes a doctor blade device, an ink reservoir and a catch reservoir. Both the ink and catch reservoirs are height-adjustable.
DESCRIPTION OF THE PRIOR ART
DE 43 40 128 C2 describes an inking unit for a rotary rotogravure printing press with a height-adjustable ink reservoir and inking roller.
DE-AS 21 39 834 discloses an inking unit for a rotogravure printing press, wherein an ink reservoir and a doctor blade device are arranged on a height-adjustable work platform.
SUMMARY OF THE INVENTION
The present invention is based on the object of producing an inking unit for a rotogravure printing press.
In accordance with the invention, this object is attained by providing an inking unit that essentially consists of a doctor blade device, an ink reservoir and a catch reservoir. The ink reservoir is height-adjustable and the catch reservoir is also height-adjustable.
The advantages which can be obtained by means of the present invention reside, in particular, in that printing or formed cylinders with diameters of different sizes can be employed in a height-adjustable inking unit. Because of this, adjustment work previously required on account of differing diameters of the printing or formed cylinders is minimized.
