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.

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.

Abstract: Device (1) for the longitudinal alignment of plate elements (2) within an infeed station of a machine working them. The aforementioned device is secured by two lateral brackets (9, 10) between which is settled a conveyor track for the said plate elements, comprising two plates (5, 6) folded downwise according to a line (7) non-perpendicular in the meaning of the shifting (3) of the said plate elements (2). The latter are moved downstream by means of at least two conveyor belts running around at least two pulleys (15, 16) secured between unmovable bearings (11-14) at the input of the said device. The device (1) has on its leading edge a protection plate (39) over which are flaps (30-32) movable and interdependent of a transverse shaft (24) connecting the leading edges of the two lateral brackets (9, 10). This shaft is moved by an alternate rotation between 0 and 45 degrees, synchronized with the production speed of the machine in order to allow the successive alignment of the said plate elements (2).
