9 ADJUSTMENTS
9.5 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.
The paper should 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 ADJUSTHANDWHEEL 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. NEVER 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 cylinder 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.
