  • Detachable inking device for a flexographic printing machine, its embodiment, cleaning and use in such a machine
    Patent number: 6543359
    Abstract: Detachable inking device for a flexographic printing machine, its embodiment, cleaning and use in such a machine. This device comprises a chambered doctor blade (9) mounted on two lever-supports (13, 14) crossed by duct joining pieces (15, 16) respectively. The lever-supports are rigidly attached to a shaft (11) about which they are pivotable and which is held between the frames (34) of said flexographic printing machine. Said chambered doctor blade (9) consists of a body (25) made of light metal material, crossed at one of its ends by a tube (26) emgerging from the bottom (28) of said body (25), and at the other end by a tube (40) having its opening part (29) at level with the bottom (28) of the body (25). The latter rests on seals (38, 39) secured to the lever-supports (13, 14) to which are attached centering and fixing means (17, 18) allowing a quick loosening of the chambered doctor blade (9) without the help of any tool.

  • Detachable inking device for a flexographic printing machine, its embodiment, cleaning and use in such a machine
    Patent number: 6530323
    Abstract: A detachable inking device for a flexographic printing machine, a manipulating device for removing and replacing the inking device, a cleaning device, and a repair station for refurbishing the inking device. The inking device itself is a chambered doctor blade (9) mounted on two lever-supports (13, 14) through which ink is supplied from a reservoir. The lever-supports are rigidly attached to a shaft (11) which is pivotable between the frames (34) of the flexographic printing machine. The chambered doctor blade has a body (25) made of light material, crossed at one of its ends by a tube (26) emerging from the bottom (28) of body (25), and at the other end by a tube (40) having its opening part (29) at level with the bottom (28) of the body (25). The latter rests on seals (38, 39) secured to the lever-supports (13, 14) to which are attached centering and fixing means (17, 18) allowing a quick loosening of the chambered doctor blade (9) without the help of any tool.
