Front Matter
Safety Statements
The ProSeal
T M
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 heatshield 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 rollerheating 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.

Theory of Operation
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 counterclockwise, 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.
fig. 4
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.

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 fig. 6 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.

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.
fig. 8
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.

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 selfignition temperature is
400°C (752°F).
Once the element is placed in the roller, reassemble all parts in the reverse order.

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.
fig. 33
If necessary, change these values as described above.
After the adjustment, remove the pressure sensors and the supports.
fig. 34
Assemble all parts in reverse order.
Now, it is mandatory to continue with the Nip Adjustment Procedure described in Section 5-2.

Adjustment Procedures
5-2. Nip 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.
Necessary tools: Allen key 4mm.
In addition, a metal adjustment sheet, having a specific thickness, is necessary.
For the ProSeal 25, the thickness of this sheet must be 0.5 mm; size: 700x250 mm.
For the ProSeal 44, the thickness of this sheet must be 1.25 mm; size: 1150x250 mm.
Approximate time: 5 minutes.
Note: the top roller must be at room temperature, before this procedure is being performed.
1. Set the roller nip opening to its maximum position by pushing and turning the nip setting knob fully
clockwise .
2. Next, the nip adjustment strips have to be loosened on either side of the machine (if not loosened already in case the previous procedure has been performed). See figure 35 and 36; the detailed adjustment strip is shown figure 37. Note that the strip must not touch the top roller bearing housing.
adjustment strip fig. 35 fig. 36
Note:
The figures 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.
3. Make sure that there is some space between the adjustment strips and the bearing housings, see figure 37.
4. Place the adjustment sheet between the rollers.
Make sure that the sheet covers the bottom roller completely.

5. Push and rotate the nip setting knob fully
counter-clockwise , until the pin, mounted in the knob, reaches its lowest position in the indent bracket. See figure 38.
The top roller is now applying pressure on the adjustment sheet.
lowest position fig. 38
6. Push the adjustment strip against the top roller bearing housing. Whilst holding the strip in this position, fasten the M5 bolt(s) firmly using the Allen key 4mm. See figure
39.
7. Perform the previous step at either side of the machine.
8. Open the roller nip again, to remove the adjustment sheet.

Adjustment Procedures
5-3.
Temperature Adjustment
Note:
•
To perform the following adjustments, it is necessary to remove the right-hand plastic side cover first; see Section 4-3: Disassembly / Reassembly Plastic Side Covers.
•
To measure the temperature of the top roller, it is necessary to have the interlocking bolts of the top cover in the unlocked position; see Section 4-1: Opening / Closing the
Aluminium Top Cover.
Necessary tools: Infrared Temperature meter, small flat head screwdriver.
Approximate time: 30-60 minutes.
The top roller temperature should be set to 160°C, ± 4°C (320°F, ± 7.5°F).
Changing the temperature to a higher value (in case it is too low) goes faster than the other way around, as the roller is heating up faster than it will cool down. Therefore it is necessary to open the top cover if the roller has to cool down, and wait approx. 15 - 20 minutes to assure that the temperature is well under the correct value.
1. Before taking a temperature measurement, the top cover has to be closed for at least 5 minutes. To do the measurement: open the top cover, and quickly measure the temperature of the top side of the top roller;
close to the middle of the machine.
See figure 40.
2. Close the cover again.
3. To change the temperature setting, insert the screwdriver in the trimpot as shown in figure 41. Rotating clockwise increases the temperature, counter clockwise rotation will decrease the temperature.
fig. 40
4. A five-degree turn of the trimpot will increase/decrease the temperature by approximately 10°C (18°F).
5. Repeat the previous steps if the temperature is not correct.
After this adjustment procedure, assemble the right-hand cover again.
fig. 41
Note:
Please do not forget to lock the top cover, as the user of the machine is not allowed to open it.

Maintenance
Section 6.
Maintenance
6-1.
Cleaning of the Machine
The laminator may be cleaned by the operator with a lint-free cloth, lightly dampened with a mild soap and water solution. Spray-on cleaners are not to be used. No part of the machine is to be immersed in water or other liquids.
6-2.
Regular Cleaning of the Rollers by the Operator
The laminating rollers of the machine should be periodically cleaned of adhesive build up that might occur during normal operation. This should be performed a few times per day, using the ProSeal
Cleaning Board.
ProSeal Cleaning Boards are specially designed to attract and capture any adhesive that may be clinging to the rollers. They are made from materials that will not damage or cause excessive wear to the ProSeal Laminator.
1.
2.
Turn on the unit and set for Hot Temperature Operation. Once the machine has reached process temperature set the Control Knob to 3/16”.
Slowly insert the Cleaning Board into the inlet opening. Ensure that the board enters centered and straight. A gentle push may be required to start the board into the machine. Hold the edges of the board until it is engaged in the unit and the laminator begins pulling it on its own.
3. The board will feed through the laminator and automatically exit at the rear of the unit. THE
BOARD WILL BE HOT! Allow the board to lie flat while cooling.
Note:
This is the only roller cleaning method operators are allowed to do.
6-3.
Cleaning of the Rollers by Service Technicians
Only service technicians are allowed to perform a thorough surface maintenance of the rollers.
This should be done once or twice per year.
To perform this cleaning procedure, the top cover has to be opened. See Section 4-1 ‘Opening /
Closing the Aluminum Top Cover. On the ProSeal 44, the feed-in table should be removed as well, see Section 4-2 ‘Feed-In Table’.
The rollers should be cleaned with a lint-free cloth, lightly dampened with IPA (Isopropanol).
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). Please make sure that the top roller is cooled down before cleaning.
6-1
February 2000
Maintenance
It’s best practice to clean the top roller first; adhesive from the top roller is likely to fall on the bottom roller.
See figure 42: cleaning the top roller, and figure 43: cleaning the bottom roller.
