position of the eccentric sleeve (if the positive rotation indentation widens, The
reverse rotation indentation becomes narrower; At this point, the core shaft of the
form dampening roller will rotate together with the eccentric sleeve of the roller),
and the indentation width will be reviewed until the indentation width meets the
requirements. After the adjustment is completed, the fastening screws on the nested
shaft heads on both sides must be tightened, and the nested shaft heads must be
firmly fixed with the coiled shaft of the form dampening roller.
4.2.6、Fine adjustment of the pressure between the form inking roller 11 and
the plate cylinder
Fig.4.2.6 Fine adjustment of the pressure between the form inking roller 11 and the
plate cylinder
Adjustment method: see Fig.4.2.6, The same as above uses light ink(such as yellow
ink) and indentation method inspection, requiring the indentation width between the
form inking roller 11 and the printing plate is 5mm, and the indentation width is
uniform in the length direction. If the indentation width does not meet the
requirements, the adjustment device at both ends of the form inking roller 11 needs
to be adjusted.
When adjusting, loosen the tightening screws on the eccentric sleeve on both sides
of the form inking roller (Note: Do not release the roller tightening screws on the
eccentric sleeve of the roller at both ends), rotate and adjust the eccentric
position of the eccentric sleeve of the steering wheel(if the positive rotation
indentation widens, The reverse rotation indentation becomes narrower; At this point,
