Ink Kneading Mechanism
A gear [C] on the drum shaft drives the ink [A] and doctor [B] rollers. The doctor
roller spreads the ink evenly on the ink roller. The ink roller drive gear [D] has a
one-way clutch to prevent the ink roller from being manually turned in the reverse
direction.
The ink roller only touches the screen during the printing process. During the
printing process, ink passes to the paper through holes in the screens and the
master. This is because the pressure cylinder below the drum holds the drum
screen and the master against the ink roller during printing.
The ink roller blade [E] (white plastic) and separation plate [F] (white plastic) scrape
off ink build-up on both ends of the ink and doctor rollers.
Metal plates [G] and [H] reduce the amount of ink leakage, if a leak occurs.
