Ink applicator drive for rotary printing machine - has actuating shaft mounted inside hollow shaft of ductor roller.

摘要

The printing machine inking roller (9) is mounted on a swivel arm (16) which swings the roller between the ductor roller (1) and the ink spreading roller (25). The swivel arm is actuated by a cam (10) which acts on the lever, which is connected by a system of pivoted links and levers to the swivel arm. The two levers (13,14) are mounted on a common shaft (2), which passes through the hollow shaft on which the ductor roller is mounted. A compression spring (18) which acts on the swivel arm keeps the roller (11) on the lever (20) in contact with the cam. ADVANTAGE - The swivel motion of the applicator roller is carried out without extra swivel shaft.
