Next, the nip adjustment strips have to be loosened on either side of the machine. See figure 28 and

bearing housing during the pressure adjustment procedure.

Note:
The figures shown above, show the adjustment
strips on the ProSeal 25; the adjustment strips on
the ProSeal 44 are positioned under the bearing
housing, they are larger, and mounted with two
bolts.
Make sure that there is some space between the
adjustment strips and the bearing housings, see
figure 30.
At the left-hand side of the machine, the
overtemperature switch has to be turned away, to
the right. In order to do this, remove the M4 socket
screw at the top of the switch, and loosen the other
fig. 30
M4 socket screw a bit, using the Allen key 3mm.
See figure 31, (2).
To place the pressure
sensors between the
2
supports, it is necessary
to open the roller nip fully.
In order to do this, push and
rotate the nip adjustment
knob, situated on the right-
hand side of the machine,
inward, and fully clockwise.
Insert the supports, together
with the sensor, all the way
into the roller journals. The
1
sensor supports should
have their flat sides facing
each other (see fig. 31, 1),
and the holes in the sensor
should fit over the pins in the
supports.
