Adjustment Procedures
February 20005-3
To insert a sensor support
into the right-hand journal of
the bottom roller, the belt
tensioner assembly has to
be removed first (already
removed in figure 32). Use
the small screwdriver to
remove the retaining clip
from the tensioner arm pivot
axis.
See figure 32.
After disassembly of the belt
and tensioner, the supports
can be inserted (1) as
previously described.
Now, push and rotate the nip adjustment knob
until the pin, mounted in the knob, falls into the
first notch (relative to top) from the indent
bracket.
See figure 33.
Pressure will be applied to the pressure
sensors, and the pressure can be read on the
PDU.
To change the pressure, place the 10mm
open-ended spanner on the M6 nut, that’s
directly under the compression spring (so, the
upper jamnut).
On the left-hand side of the machine, it’s best
to remove the blue connector from the
overtemperature switch, to ease access with
the spanner. See figure 34.
Rotate clockwise to decrease the pressure,
counter-clockwise to increase the pressure
(seen from above).
The pressure settings for each PDU display
(so, for either side of the machine) should be
as follows:
ProSeal 25 – 35 kilograms.
ProSeal 44 – 46 kilograms.
If necessary, change these values as
described above.
After the adjustment, remove the pressure
sensors and the supports.
Assemble all parts in reverse order.
Now, it is mandatory to continue with the Nip Adjustment Procedure described in Section 5-2.
