ABSTRACT:
In an inking apparatus for a printing press, a rotary lever is rotated by adjusting means disposed between a roller arm and the rotary lever around an axis parallel to a swing shaft of the roller arm to move a cam follower mounted to the rotary lever, and a cam mounted coaxially with a plate cylinder is rotated by cam driving means to select pressing state and unpressing state of the ink form roller through the cam follower, thereby preventing the nip pressure from being varied by skewing adjustment of the plate cylinder.
