A device is designed to sealingly close an end of a chambered doctor blade (K). The chambered doctor blade (K) has an elongate frame (K1) and two elongate doctor blades (K6, K7), which are arranged on the frame (K1) and define, together with the latter, an elongate chamber (K10), which is adapted to hold, for instance, ink. The chambered doctor blade (K) has an elongate opening (K11) for abutment, in an operative position of the chambered doctor blade (K), against a rotatable cylinder (V) included in a printing unit. The end sealing device comprises first and second sealing sheets (20, 30) which are mountable to at least partially overlap each other and sealingly close an opening (K11) in one end of said chamber (K10). The sealing sheets (20, 30) are arranged relative to each other in such manner that the first sealing sheet (20) is sealingly applicable against said frame (K1) and, in the operative position of the chambered doctor blade (K), is located at a distance from a circumferential surface of said cylinder (V) and in such manner that the second sealing sheet (30) is sealingly applicable against said doctor blades (K6, K7), and, in the operative position of the chambered doctor blade (K), abuts against said circumferential surface.
