Front Matter Safety Statements The ProSeal 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.

Front Matter 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! fig.
AC motor to maintain a constant process speed. The ProSeal laminators have been designed to be used with ProSeal Pouch Boards and ProSeal Flexible Pouches. When used with these products, one is able to mount, mount and laminate, and encapsulate prints in one step.
230VAC/50Hz 7A 230VAC/50Hz 9A The ProSeal machines must be installed next to the power outlet; extension cords are not to be used. The plug and the outlet must be easily accessible by the operator. For the US versions, there are two types of outlets (receptacles), shown below.
Installation Wirecolours: General (EU) Name Blue White Neutral Yellow/Green Yellow/Green Ground Brown Black Phase (Live) 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. •...
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.
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.
Disassembly / Reassembly Procedures 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.
Disassembly / Reassembly Procedures 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.

Disassembly / Reassembly Procedures 2. Remove the self-tapping screw, situated at the rear side of the machine, using the TX25 driver, as shown in figure 11. fig. 12 fig. 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.
Disassembly / Reassembly Procedures 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.

Disassembly / Reassembly Procedures 4. Loosen the screw, which attaches the heater wire to the Solid State Relay. See figure 17. fig. 17 fig. 18 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.
Disassembly / Reassembly Procedures 4-5. Software The Control System of the ProSeal Laminator is software driven. The software resides in a small embedded controller, mounted on the Control PCB. Necessary tools: small flat-head screwdriver. Approximate time: 3 minutes. Note: To change / upgrade the software, it is necessary to perform the ‘Plastic Side Covers’...
Disassembly / Reassembly Procedures 4-6. Rear Panel Necessary tools: Phillips crosshead screwdriver (medium), open-ended spanner 8mm, knife. Necessary materials: two tie-wraps (2.5 – 3 mm wide). Approximate time: 10 minutes. Note: To remove the rear panel, it is necessary to perform the ‘Plastic Side Covers’ Procedure (see Section 4-3) first.
Disassembly / Reassembly Procedures 9. Apply the two new tie-wraps exactly on the original positions (into the holes), put the blue connector back onto the overtemperature switch, and mount the ground wire back to it’s position. Put the serrated washers back the way they came off: one on either side of the two wire-eyelets. 4-7.
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.
Page 21
28 fig. 29 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.

(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.
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.

Adjustment Procedures 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.
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;...
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’.

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. fig. 43 fig. 42 February 2000...
Troubleshooting Section 7. Troubleshooting 7-1. Troubleshooting Problem: The power LED does not come on, when the nip setting knob has been set to one of the nip settings (board thicknesses). Causes: The power cable has not been plugged in the mains wall outlet. Solution: Plug the power cable into the mains outlet.
Page 29
The Pouchboard is too thick for the chosen nipsetting. Solution: Check the nipsetting that corresponds to the boards used. Boards of another make are used. Solution: Use only ProSeal Pouchboards. The nip adjustment is not correct. Solution: Perform the Nip Adjustment procedure (see Section 3-2). Problem: The quality of the lamination is poor: silvery areas on dark surfaces are visible, or the edges of the image are not sealed well.
