摘要： A flexographic printing unit (17) for a converting machine (10). The flexographic printing unit comprises a flexographic printing assembly (28) including a printing cylinder (30), an anilox cylinder, a counter cylinder (32) and a doctor blade chamber (36). The printing cylinder being arranged vertically above the counter cylinder and configured to print on a top side (S1) of a sheet (1). The flexographic printing unit comprises a fixed frame portion (102) and a movable frame portion (104), and the printing cylinder, anilox cylinder and the doctor blade chamber are attached to the movable frame portion and the counter cylinder is attached to the fixed frame portion. The movable frame portion being vertically movable between an operating position where the printing cylinder is positioned against the counter cylinder and a service position where the printing cylinder is further distanced from the counter cylinder.

摘要： A doctor blade for spreading a coating solution supplied to a roll surface of an anilox roll rotatable about a rotation axis over the roll surface is in a longitudinal plate shape. The doctor blade includes a long edge and bent portions. The long edge is set against the roll surface of the anilox roll along the rotation axis. The bent portions are at ends of the long edge and at angles to the long edge.

摘要： A device for printing on hollow bodies has a plurality of printing units each having a printing cylinder. At least one of the printing units has an inking unit having a chambered doctor blade that provides printing ink. The chambered doctor blade system has at least one ink pan and a doctor blade holder in a single assembly. The single assembly of the chambered doctor blade system is retained in the inking unit only on one side. The assembly of the chambered doctor blade system forms a cantilever arm on a side frame of the inking unit. The assembly of the chambered doctor blade system can be moved axially parallel to the anilox roller and can be removed from the inking unit by that movement.

摘要： An apparatus includes a washing water supplying path connected to an ink chamber, including a seal blade and a doctor blade slidably contacting an outer circumference of an anilox roll; a washing water supplier for supplying washing water to an inside of the ink chamber through the washing water supplying path; a supplying path opening/closing device that opens and closes the washing water supplying path; a washing water recovering paths connected to the ink chamber; a suction recovering device that recovers the washing water in the ink chamber by suction through the washing water recovering path; and a controller that controls operations of the washing water supplier, the supplying path opening/closing device, and the suction recovering device. The control mode includes a decompression control mode in which the seal blade is elastically deformed towards the ink chamber by decompressing the inside of the ink chamber by recovering the washing water.
