Cutterhead Cylinder to Bottom Blade
Adjustment
IMPORTANT: PREVENT DAMAGE - It is
essential that the relationship between the bot-
tom blades and the cutting cylinders is kept in
good adjustment in order to ensure good cutting
performance,
minimum power consumption and prolonged
life for the cutting edges.
Carry out the following procedure before com-
mencing work and
re-check the settings every few hours.
Check that the cutting cylinder is correctly set to
the bottom blade by holding a thin piece of paper
between the cutting cylinder and the bottom blade
as shown. Carefully rotate the cylinder as shown
and check that the paper is cut cleanly at all points
along the length of the blade. Hold the paper at 90̊
(right angles) to the bottom blade to obtain the
correct cutting action.
WARNING: PREVENT ACCIDENTS - Ensure
that people are clear of the cutting cylinders as
rotation of one may cause others to rotate.
If adjustment is necessary proceed as follows;
Release nut ‘A’ ¼ turn both ends.
Turn hand wheel ‘B’ each end alternately whilst
rotating the cutting cylinder backwards until the
bottom blade is in ‘fleeting’ contact with the cyl -
inder along its entire length. Re-check the cutting
action along the length of the bottom blade using a
thin piece of paper making marginal adjustments as
necessary.
Tighten nut ‘A’ both ends.
If it is impossible to obtain a good clean paper cut
across the entire length of the bottom blade it will
be necessary to carry out the back lapping proce-
dure to reprocess the cutting edges. In severe cases
it will be necessary to regrind the cutting cylinder
and the bottom blade, refer to BACK LAPPING /
GRINDING .
