Abstract
A cleaning apparatus for the inking mechanism of an offset printing machine including an ink fountain roller, an ink lifter roller and ink take-off roller associated with an ink roller train wherein the ink lifter roller is journalled for rotation on one end of a lever arm pivotally supported intermediate the ends thereof by an eccentric coupling. A working cylinder and an articulated link rotate the eccentric coupling and move the lever arm and ink lifter roller between a cleaning position, wherein the ink lifter roller simultaneously contacts the ink fountain roller and the ink take-off roller, and a printing position, wherein the lever arm pivots about the eccentric coupling to oscillate the lifter roller between contact with the ink fountain roller and the ink take-off roller. A cam follower disposed at a second end of the lever arm is engageable with a rotatable control device for pivoting the lever arm about the eccentric coupling to oscillate the ink lifter roller between contact with the ink fountain roller and the ink take-off roller when the lever arm is moved to the printing position; the cam follower being disengaged from contact when the control means with the lever arm is moved to the cleaning position.
