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 rubber cap on the non drive end bearing
housing can be removed and the hexagon end of the shaft turned using a spanner.
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 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. 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 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.
