9.6 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 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.
