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. The body (25) comprises two planar outwardly slanted projecting parts against which are adhesively attached two doctor blades elements. The doctor blade elements are also held at their ends by a supporting piece (21) havin…
