Laminating Pressure Adjustment

Note:
•
To perform the following adjustments, it is necessary to remove both plastic side covers
first. See Section 4-3: Disassembly / Reassembly Plastic Side Covers.
•
Note: the top roller must be at room temperature, before this procedure is being performed.
•
Next, the heating element, including both heater brackets, has to be removed. See the
'Heating Element' Procedure described in Section 4-4.
•
After completion of the Laminating Pressure Adjustment procedure, it is mandatory to
continue with the Nip Adjustment Procedure described in Section 5-2.
Necessary tools: 10mm open-ended spanner, small flat-head screwdriver, Allen key 2mm.
Approximate time: 15 minutes.
To adjust or set the laminating pressure, the following special devices are required:
The Pressure Display Unit (PDU).
This unit has to be plugged in a wall
socket; the two pressure sensors can be
plugged in at either side of the PDU. The
pressure (actually: force) display reads in
Kilograms. See figure 25.
Together with the PDU, a set of sensor-supports has to be used. Each machine type needs a different
set of sensor-supports. For the ProSeal 25, a set, shown in figure 26 is necessary; figure 27 shows the
set for the ProSeal 44.
Note: each figure shows only half the set.
