Abstract
A chambered doctor blade assembly which can be placed against a roller of an inking unit of a printing machine, in particular onto an engraved roller, has a chamber connected to the surface of the roller by means of an orifice through which printing ink can flow. The orifice can be closed and re-opened by means of a closing element which is arranged within the chamber and which can be brought into a closing position. When the closing element is in the closing position, printing ink can continue to flow through the chamber.
