CUTTING CYLINDER TO BOTTOM BLADE ADJUSTMENT ______________
To check that the cutting cylinder is set to the bottom blade correctly, hold a piece of thin paper between the
edge of the blade and the spiral cutters and turn the cylinder manually using a tool (Section 7.11).
The paper must be cut cleanly along the total length of the bottom blade, if not, some adjustment may be
necessary, BUT DO NOT OVERTIGHTEN. Alternatively if the cylinder is worn it may require back lapping
before adjusting.
TO ADJUST HANDWHEEL TYPE:
1.
To adjust the cylinder to the bottom blade turn alternately left and right
hand handwheels (A) clockwise to put on cut. A 'notching' effect will be felt
as the handwheel is rotated in a clockwise direction this 'notching' is moving
the cylinder in increments of approximately 0.035mm (0.0014in) towards the
bottom blade.
2.
The correct 'on cut' must be achieved with the adjustment mechanism
'slack' (i.e. between 'notches'). A requirement of the hand adjustment is that
the cylinder must always be moved towards the bottom blade (i.e. clockwise
rotation of handwheels) to attain the correct cutting relationship of cylinder
and bottom blade. DO NOT PLACE CYLINDER HARD 'ON CUT', and by anticlockwise rotation of handwheel
try to attain the correct cutting relationship.
3.
If cylinder is placed too hard 'on cut' it must be adjusted to clear the bottom blade by anticlockwise rotation
of handwheel then re-adjusted back down to the bottom blade.
4.
THIS IS A SELF LOCKING MECHANISM THERE BEING NO NECESSITY TO UNLOCK OR
LOCK THE MECHANISM.
TO ADJUST SPANNER TYPE:
1.
Release the two nuts which hold the bearing housings to the side plates.
2.
To adjust the cylinder to the bottom blade turn alternately left and right
hand nuts, clockwise to put on cut
3.
If a is placed too hard 'on cut' it must be adjusted to clear the bottom
blade by anticlockwise rotation of nuts then re-adjusted back down to the
bottom blade.
4.
After adjusting securely tighten screws.
