MANUAL OUTER FOLD ROLLERS Section 8<br />
Note ........Permissible lateral movement is less than 0.025mm<br />
(0.001”). and can be felt either at the top or the bottom of<br />
the calliper.<br />
4. Using a suitable punch, lightly tap (towards the calliper),the<br />
end of the left-hand linear bearing that is allowing sideways<br />
movement and repeat check 3.<br />
5. Check the moving calliper for movement and if it will not<br />
slide up and down go to step 6 .If it will slide up and down<br />
go to step 7<br />
6. Using a suitable punch, give both of the screw heads a light<br />
tap and repeat checks 3 and 5 after each tap.<br />
7. Fully tighten the clamp screws for the left-hand linear<br />
bearing, repeat checks 3 and 5, and carry out the above<br />
procedure as often as is necessary to obtain the correct<br />
setting.<br />
8. Push the right-hand linear bearing (after slackening both<br />
screws) against the bearing plate (as indicated) and lightly<br />
tighten both screws.<br />
9. Carry out the above procedure from step 5 for the righthand<br />
linear bearing, ( going back to step 3 as required).<br />
Note ........All the screws must be fully tightened on completion.<br />
8.3 .......Outer Fold Rollers - Pressure Springs<br />
The pressure springs should be adjusted so that the 2mm<br />
dimension as shown in fig 8.41 is obtained between the pressure<br />
pad and the calliper.<br />
Carry out the adjustment using a 2.5mm allen key in the adjusting<br />
screw, (it may be easier if the allen key is shortened enough to<br />
pass over the fold roller),<br />
Note ........An excessive gap will limit how wide the callipers will<br />
open to accept paper, but must be equal both sides.<br />
