Abstract: A device (10) for fastening a doctor blade (3) to a doctor blade (1) chamber body (2) comprising: at least one clamping flange (11) configured to press the doctor blade (3) onto the doctor blade (1) chamber body (2), at least a first fastener (20), and at least one second fastener (30), wherein the first fastener (20) comprises at least a first retaining section (21) having an upper end (21a) and a lower end (21b), a second section (22) different from the first retaining section (21), and wherein the second fastener (30) comprises at least a first portion (31) having at least one retaining element (34a), a second portion (32) having at least one retaining element (34b), an intermediate portion (33) devoid of retaining element and arranged between the first portion (31) and the second portion (32).

Abstract: A main body of doctor blade chambers including a first portion configured to hold a first doctor blade, a second portion configured to hold a second doctor blade, a third portion connecting the first portion and the second portion, a cavity intended to receive ink and defined at least by the first portion, the second portion and the third portion, characterized in that the main body is a single closed hollow profile extending along a longitudinal main axis X-X, the main body being made of pultruded composite material.

Abstract: A doctor blade, intended for a doctor blade chamber (6) for a flexography printing unit (1) equipped with a screened cylinder (4), presents in the form of a rectangular blade, with a functional longitudinal side (34) of which a longitudinal edge is capable of making contact with the screened cylinder (4), a longitudinal fastening side (33) and two lateral sides (36, 37). The doctor blade comprises at least one opening located towards the functional longitudinal side (34) and towards the first of the two lateral sides (36, 37).

Abstract: Method for loading and exchanging the rollers of the printing units of a printing machine and a device for working the method, the device loading station including a handling carriage for engraved rollers, a storage station for rollers, a reserve station at each of the printing units, a robot for transporting the engraved rollers, either from the loading station or from the storage station to a ready position located in the reserve station. The robot takes an engraved roller either from a reserve position or from the storage station or from the loading station and brings the roller into a working position. The robot is also able to withdraw an engraved roller from its working position in order to bring it either into a reserve position, or into the storage station or into the loading station.
