ABSTRACT:
An inking device for a printing machine, which has both a nip pressure adjusting mechanism, adjustable from the outside during the running of the machine, and a follow-up mechanism of a nip pressure to a movement of a plate cylinder and increase a degree of freedom in handling each member for the inking device enable the setting thereof to be easier. The inking device is equipped with two supporting levers 14 which rotatably supports the second and third form rollers 13b and 13c and are usually biased by compression coil springs 23 to push the second and third form rollers 13b and 13c against a plate cylinder 4, and two rolling member supporting levers 25 supporting a bearing roller 27 to contact a roller-lifting cam 7 and another bearing roller 27 to contact a plate cylinder follow-up cam 6 supported by the second eccentric bearing 2, wherein each of the supporting levers 14 and each of the rolling member supporting levers 25 are interconnected by a screw rod 29. A pitch of a screw to be screwed into the supporting lever 14 and a pitch of a screw to be screwed into the rolling member supporting lever 25 are different from each other so that a relative position between the supporting lever 14 and the rolling member supporting levers 25 is made alterable.
