Safety Statements
The ProSealTM laminators have been designed with operator safety as a primary objective; however,
operators must be familiar with the controls, as well as the operation before using the unit.
The electrical and drive-system components are isolated from contact with the operator by enclosing
them within plastic end covers that are bolted on. Only qualified service technicians should remove
these protective covers after power to the machine is removed including disconnecting the power
cord.
The heated top roller can reach temperatures of 160C (320°F). For operator safety, a protective heat-
shield is mounted over the top roller, and attached to the top aluminum extrusion. Adequate ventilation
is guaranteed; because of this, the outside temperature of the extrusion will never exceed 45°C
(113°F).
Only qualified service technicians should remove the top extrusion in order to clean
the rollers if necessary.
Safety Features
The material inlet opening has a height that is in accordance with EN294 clause 4.5.2; the IEC1032
test finger cannot enter this opening.
The heating system is provided with an over-temperature device, which will shut off the top roller-
heating element once a heating system failure occurs.
Caution
Everyone working around the laminator must avoid wearing loose fitting clothing
(ties!) or dangling jewelry, which could catch in the laminator rollers.
Technical Service hazards
Fire hazard – The laminator contains a heated roller which reaches temperatures of 160°C
(320° F). There is a danger of severe burns if the heated roller is touched during servicing.
Mechanical hazard – Failure to use caution near exposed rollers could result in physical
injury.

2-1-2. Workspace Requirements
•This unit should be situated away from heat sources such as heat registers or stoves.
•The laminator’s location or position should not interfere with its proper ventilation.
•There should be enough space around the laminator to feed-in, exit, and trim mounted and/or
laminated images.
•The background dust level must not exceed that found in a typical office/computer room
environment.
•The work area should be level, flat, and well lit.
2-2. Setup
Procedure:
1. Open the box, and lift the machine out (at least two persons necessary!). Grasp the machine 8”-
10” (200mm-250mm) from either side, at the bottom aluminum extrusions. Be careful: the
polyethylene bag is slippery!
2. Place the machine on the work area described under 2-1-2.
3. Remove the protective polystyrene foam end covers.
4. Remove the polyethylene bag.
5. Remove the protective sheet, placed between the rollers. To do this: push the knob, situated at
the right-hand side, fully inward, and rotate fully clockwise.
6. Check for damages.
7. Plug the power cable into the grounded outlet as described under 2-1-1. The machine will now
start and heat up.

Theory of Operation
February 20003-1
Section 3. Theory of Operation
3-1. Control Knob
The Control Knob (see figure 4) is located on the right hand side of the laminator and is operated from
the front of the machine. The Control Knob has four (4) purposes:
1. Turn the power on.
2. Turn the heat on.
3. Turn the rollers on.
4. Adjust the height of the rollers.
The Control Knob can be operated by pushing it in
approximately 1/4” (6mm) to the left. Once the
knob has disengaged from the stop, it may be
rotated forward or backward (clockwise or counter-
clockwise, viewed from the right hand side of the
unit).
To switch the power on, push the knob in and
rotate it slowly towards you (counter clockwise as
viewed from the right side of the unit). The top LED
will light up to indicate that the power is on.
Continue to rotate the knob until the desired measurement corresponds with the indicator window at
the base of the knob. Inside the window, the rotation possibilities are shown. Select the measurement
that indicates the thickness of the material you will be using with the machine. Releasing the knob so
that it moves back to the right and clicks into place will set the rollers for use. The measurements on
the knob, ¼”, 3/16”, 1/8” and 1/16” (6, 5, 3, 1.5 mm) correspond to ‘Pouch board thickness’. There is
also a fully closed stop for future film only applications.
To turn the laminator off, grasp the control knob and push to the left, rotate the knob away from you
as far as it will go (clockwise). This will shut off the machine and open the rollers to permit objects to
be removed.
Internal functionality
See figure 5.
Inside the machine, a rod is mounted
between the left- and righthand framesheets.
The knob is mounted on the rod; it allows
axial movement, but no radial movement. The
knob is provided with a pin (1), that falls in the
indents (2) of a bracket (3). The same rod is
provided with an eccentric (4) on either side
of the machine. These eccentrics push or pull
the arms (5), where the top roller is mounted
in, upward or downward. The mains switch is
mounted in such a way, that it switches the
power off once the are is in its highest
position.

Theory of Operation
February 20003-2
3-2. Control Panel
The Control Panel (see figure 6) is located on the front right of the machine and has three LED
indicators. A diagram of the Control Panel is shown in figure 7.
1. The top LED when lit indicates the machine is
plugged in and the power is on.
2. The middle LED indicates if the heat is on. Heat
is required for ProSeal Pouch Boards and
ProSeal Flexible Pouches. If lit, the laminator is
in Hot Operation Mode and will heat up to its
factory setting. If not lit, the laminator is in Cold
Operation Mode.
3. The bottom LED is the Temperature Ready
Indicator. If flashing slowly this indicates the
laminator is heating up and has not yet reached
process temperature. A steady light indicates
the unit has reached process temperature and
is ready for use. A rapid blinking light indicates
that the machine is too hot. This occurs when changing from Hot Mode to Cold Mode. In this case,
a steady light indicates the machine has cooled sufficiently for cold processes.
Below the LED lights are two Push Buttons.
1. The top button controls the heating of the roller; it switches the heater on or off. Pushing this
button toggles the machine from Hot to Cold or Cold to Hot Operation. The bottom LED light when
constantly on, will indicate the appropriate temperature as been reached.
2. The lower button reverses the direction of the motor. The motor will continue to run in reverse until
the button is released. This is used to clear jams or foreign objects, should one be drawn into the
laminator.

Section 4. Disassembly / Reassembly Procedures
4-1. Opening / Closing the Aluminum Top Cover
Necessary tools: medium flat head screwdriver.
Approximate time: 1 minute.
To open the cover, do the following steps:
1. Insert the screwdriver in one of the holes,
situated on the top of the cover. Make sure,
that the head fits in the screw, mounted
directly underneath this hole. See figure 8.
2. Rotate the screwdriver approximately ¼
turn; the direction is not important, as the
screw is a so-called ‘quarter-turn snap-in
screw’.
3. Repeat this at the other side of the top
cover.
4. Open the top cover, until it rests on the
feed-in table.
To close and lock the cover, proceed with the following steps:
1. Do not close the cover yet, but rotate both screws back ¼ turn (to their original position). This is
easier when the cover is still open.
2. Now close the cover.
3. Press, using the screwdriver, both screws until they snap back into their locks.
Note:
When performing the Temperature Adjustment Procedure, it is convenient to close the cover without
locking the screws. This is called the ‘unlocked position’.
Note:
Please make sure, that after any procedure, requiring the top cover to be opened,
the top cover is closed and locked. For safety reasons the operator is not allowed
to have free access to the hot roller and roller nip.

4-2. Feed-in Table
Necessary tools: medium flat head screwdriver.
Approximate time: 1 minute.
To remove the feed-in table, do the following steps:
Insert the screwdriver in one of the holes,
situated on the feed-in table. See figure 9.
1. Rotate the screwdriver approximately ¼
turn; the direction is not important, as the
screw is a so-called ‘quarter-turn snap-in
screw’.
2. Repeat this at the other side of the top
cover.
3. Lift the table approximately 20 mm (3/8”) by
means of the two knurled knobs, and slide it
straight out of the machine.
To insert and lock the feed-in table, proceed
with the following steps:
1. Insert the table back into the machine, and make sure that it goes in straight, otherwise it might
get stuck.
2. Once the table falls into it’s position, rotate the screws back ¼ turn (to their original position). Use
the same screwdriver to press both screws until they snap back into their locks.
Note:
Please make sure, that after any procedure, requiring the feed-in table to be
removed, the feed-in table is closed and locked. For safety reasons the operator is
not allowed to have free access to the hot roller and roller nip.
4-3. Plastic Side Covers
Necessary tools: hexalobular screwdriver TX25, Allen key 4mm.
Approximate time: 5 minutes.
Note:
To remove the covers, it is necessary to
perform the ‘Opening / Closing the
Aluminum Top Cover’ Procedure, described
in Section 4-1.
To remove the side covers, do the following
steps:
1. Remove the two self-tapping screws, using
the TX25 driver, as shown in figure 10. The

4. Loosen the screw, which attaches the heater wire to the Solid State Relay. See figure 17.
5. Remove the heater bracket on the right hand side of the machine (see figure 18), and slide the
heater wire out of the slot, that’s in the heater bracket.
Now, the heating element can be taken out of the roller.
Note:
When a heating element has to be installed into the roller, the quartz tube has to be cleaned first.
Proceed as follows:
Insert the heating element, with the end having the shortest wire, into the roller core. Make sure,
that the wire is bent straight, to smoothen the insertion.
Whilst inserting, clean the quartz tube with a lint-free cloth, lightly dampened with IPA (Isopropanol).
Do not touch the quartz tube with your fingers!
This is important, because fingerprints will burn when the heater is on, and can possibly damage the
quartz tube.
See figure 19.
Always be very careful
when using IPA! IPA is
very flammable!
The flash point of IPA is
11°C (51.8°F). The self-
ignition temperature is
400°C (752°F).
Once the element is placed in the roller,
reassemble all parts in the reverse order.

Adjustment Procedures
February 20005-1
Section 5. Adjustment Procedures
5-1. 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.
The tools shown above have to be inserted in the roller journals, at either side of the machine.
To insert the tools into the top roller, the heating element, including both brackets, has to be removed
first. See the disassembly / reassembly procedure in Section 4-4.
