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.

Chambered doctor blade assembly

A device for metering and equalizing an ink layer on the surface of a printing machine roller, in particular on the surface of an ink applicator roller in the inking unit of a printing machine, the surface being additionally wetted with dampening medium. The device contains at least two doctor blades which are arranged preferably at a short distance one behind the other in the direction of rotation of the roller and rest under pressure against the surface of the roller and of which a front doctor blade, with respect to the direction of rotation of the roller, has a doctor blade edge radius such that essentially only the dampening medium, but not the ink layer, can be wiped off from the surface of the roller by said front doctor blade, while a rear doctor blade, with respect to the direction of rotation of the roller, has, by comparison, a smaller doctor blade edge radius such that at least part of the ink layer which has remained on the surface of the roller can be wiped off.
