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.

Note:

When performing procedures that require the side covers to be opened, ensure that

the power cable is disconnected from the mains. Several parts, like the mains switch

(1) and the overtemperature switch (2), could cause electrical shock if the power is not

disconnected!

Section 1. Machine Characteristics

1-1. Machine Description

The ProSealTM

25 and ProSealTM 44 laminators are electro-mechanical devices containing two silicone

rollers, a heating element for the top roller, an electronic PIZ controller for a fixed temperature, and a

synchronous drive AC motor to maintain a constant process speed.

The ProSealTM

laminators have been designed to be used with ProSealTM Pouch Boards and ProSealTM

Flexible Pouches. When used with these products, one is able to mount, mount and laminate, and

encapsulate prints in one step.

Each machine is provided with a User Manual; the purpose of this manual is to outline the materials

and processes when using ProSealTM

supplies using this laminator, to create signs, displays, and

flexible graphics with professional results. The manual includes instructions of various laminating

procedures, which are meant to give the user comprehensive information needed for the efficient use

of his laminator.

These machines have not been tested with any other materials and are not recommended for use with

products other than ProSealTM

supplies.

The US versions of the ProSealTM

machines are provided with fixed powercables and NEMA plugs; the

European versions are provided with Euro appliance inlets (see also Section 8).

The ProSealTM

laminators meet the Machinery Directive (89/392/EEC & applicable amendments). They

are ETL and cETL listed per directive UL 1950 3rd Edition 1995 and CAN/CSA C22.2 No. 950-95.

Section 2. Installation

2-1. Preinstallation

The following requirements are applicable:

2-1-1. Electrical Requirements

This unit should only be connected to a power supply outlet of the voltage, amperage, and frequency

marked on the rear panel. The laminator has a grounded plug (three prongs). To reduce the risk of

electrical shock, this plug is intended to fit only a grounded outlet of the proper amperage, and in only

one way.

The US versions of the ProSealTM

machines are provided with fixed powercables and NEMA plugs; the

European versions are provided with Euro appliance inlets (see also Section 8).

The electrical specifications of the machines are:

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.

fig. 5

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.

Disassembly / Reassembly Procedures

February 20004-1

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.

February 20004-2

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

Disassembly / Reassembly Procedures

February 20004-3

2. Remove the self-tapping screw, situated at the rear side of the machine, using the TX25 driver, as

shown in figure 11.

3. Remove, using the Allen key 4mm, the two M5 socket screws, situated at the bottom of the cover.

It’s best practice to slide the machine to the edge of the table or counter where it’s placed. See

figure 12.

4. Carefully remove the right hand cover from the

frame of the machine. Now, a flatcable,

connected to the Control PCB, will become

visible. Hold the cover with one hand, whilst

removing the flatcable connector from the

PCB. See arrow in figure 13.

5. The procedure for the left-hand cover is

similar, though it’s obvious that there’s no

flatcable on this side.

Assembly of the cover is in reverse order.

Note:

Make sure, that the flatcable has been placed back onto the PCB connector. Take

care, that the flatcable is not twisted.

4-4. Heating Element

Necessary tools: Allen key 3mm.

Approximate time: 10 minutes.

Note:

To disassemble / reassemble the heating element, it is necessary to perform the ‘Plastic Side

Covers’ Procedure, described in Section 4-3.

Make sure that the power cord is disconnected from the mains!

The heating element (see figure 14), is a quartz

tube, having a spiral wound filament mounted

inside.

The quartz tube is fragile; take care when

handling the element.

To exchange the heating element, perform the

following procedure:

1. Remove, on the left-hand side of the machine, the blue fast-on connector (1) from the

overtemperature switch (2). See figure 15.

2. Slide the heater wire out of the slot that’s in the heater bracket.

Disassembly / Reassembly Procedures

February 20004-5

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.

Note:

Do not forget to attach two new tie-wraps, and

mount them exactly as the two that were

removed previously.

behind it.

4. Now you can remove the Solid

State Relay, together with the

bent sheet.

5. When mounting the Relay,

make sure that the four

clamping screws and the two

M4 bolts are tight. Don’t forget the serrated washers that belong under the M4 bolt heads.

Note: make sure, that the relay is mounted in the proper way: the coding on the blue wires

should correspond with the numbers on the relay; the two black wires on clamp no. 1, the wire

from the heating element on clamp no. 2.

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.

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

29; the detailed adjustment strip is shown figure 30. Note that the strip must not touch the top roller

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

M4 socket screw a bit, using the Allen key 3mm.

See figure 31, (2).

To place the pressure

sensors between the

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

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.

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.

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.

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.

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

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.

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.

Note:

Please do not forget to lock the top cover, as the user of the machine is not

allowed to open it.

Maintenance

February 20006-1

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. Turn on the unit and set for Hot Temperature Operation. Once the machine has reached

process temperature set the Control Knob to 3/16”.

2. 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.

Maintenance

February 20006-2

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.
