Section 6 OUTPUT SHAFTS
Note: ...... Before removing the upper & lower hubs from their
shafts, study the hubs and note the orientation of the
tapped holes in the hub faces. It is important that the
orientation is maintained during re-assembly as it will be
impossible to follow the setting instructions for
perforating & slitting (See the operators guide), if the
hubs are incorrectly installed.
Re assemble in reverse order (see Note above) , but note that
bearings are a slide fit in their housings so if ANY force is required,
something is wrong and should be investigated before proceeding.
There are no adjustments for the input rollers or output shafts, but
you should ensure that the shafts are free to move sideways under
the control of their springs
(waved washers or disc springs -Note
1) .
Check this by holding each shaft or input roller in turn & pulling it
against it’s springs. The shafts should return to their operating
positions upon release.
(See Note 3 below)
Note 1* ... Some machines may have their control springs (waved
washers or disc springs) on the clutch side.
Note 2..... Before carrying out this check, you should ensure that
any perforating, slitting or scoring units are separated.
Note 3..... Input rollers may not return to their operating position
immediately, due to the friction between them so rotate
the machine by hand and they should move back within a
few turns.
Note 4..... The operator side bearings on the output shafts are a
press fit and do not normally need replacing, but if they
do, they should be pressed off and on to the shaft using a
proper bearing press and following the bearing
manufacturers guide-lines.
