ABSTRACT:
The wiping device operates with at least one cylinder (3) which receives the ink raised from the printing plates and against which rests a doctor blade (4) which removes the ink from said cylinder (3). In order to clean the doctor blade (4) reliably from ink during the printing operation, there are mounted on the opposite longitudinal edges of said doctor blade (4) wall parts (6) which are U-shaped in the plan view and whose U-limbs (6a) are directed towards one another. Between said U-limbs (6a), an ink slide (8) is moved constantly back and forth on the doctor blade surface by a drive device, the side parts of said ink slide facing the wall parts being adapted to the design of said wall parts. Installed on the back of the doctor blade (4) on each side is an ink pump whose slot-shaped inlet opening (12) extends between the U-limbs of the relevant wall part (6). The ink slide (8) which is moved back and forth acts like a displacement body and pushes the ink passing onto the doctor blade alternately into the inside space bounded by the one or by the other wall part (6), where it is conveyed away by the ink pump and fed to a container.
