Page 7: Principles Of The Lamination Process
PRINCIPLES OF THE LAMINATION PROCESS The lamination process uses a specialised laminating film consisting of a heat stable base film (polyester) coated with an adhesive co-polymer resin. Whilst dry to touch at room temperatures, at approx 250 o F the resin softens into a very aggressive contact adhesive. -
Page 8: Warm Up (Without Film Loaded)
WARM-UP (Without film) (Refer to page 15 for warm up with film loaded). Connect machine to a single phase power source. Check that the Forward/Reverse control is in the OFF position. Switch 'ON' main power switch. The red "power" light should glow. Dial the thermostat (heater) knob to 270 o F. -
Page 9: Loading Laminating Film
The first steps in this process are to remove the remnants of the old roll of film (See Section 9.9, Page 18) and if necessary, to clean the nip rollers (See Section 10.1, Page 22). Also see page 8a for USI colour code. - Page 12 The bottom idler bar should be in the "load" position i.e. nearest the roll of film. Thread the bottom film web under the bottom idler bar and, pulling it towards you, align it with the top film web and place it against the top film surface, which should now be tacky so that they bond together. (See Fig 7.2).
- Page 13 It is essential that the bottom (moveable) idler bar is locked into the run position. With both hands on each end of the idler bar push it gently towards the back of the machine until it locks into place. Replace feed table and place feed plate in position. (See Fig.7.4) Fig 7.4 POSITIONING FEED PLATE 7.10 Select "Forward".

This could take 3 feet through the machine, depending on the accuracy of your original alignment, etc. 7.14 Turn the fans on, you are now ready to Laminate.

Page 17: Warm Up (With Film Loaded)
WARM-UP WITH LAMFILM ALREADY LOADED The normal method of warming up the machine will be with film loaded. Check that the "Forward/Reverse" knob is in the stop position. Turn on the main switch key (red power light should glow). Dial the thermostat (heater) knob to the warm up temperature of 270 o F. Wait at least 15 minutes. -
Page 18: Laminating
LAMINATING Cold Spots Good laminating film resins activate at around 212 o F and to produce adequate bond, they need to be laminated with hot nip rollers. The rubber nip rollers are heated by exposure to radiant heat from the surrounding heat shoes. -
Page 19: Feeding Technique
Feeding Techniques Ensure the article to be laminated is flat and free of curl or creases (See Section 12.1, De-curling, Page 24). Lay the article flat on the feed table and with your fingers slightly stretch it to the sides to flatten out any creases or curl on the leading edge. -
Page 20: Fan Control
Thick Stock Your laminator is designed to laminate items up to 1/8" in thickness, processing any item heavier than this may damage the gearbox (and void your warranty). The thickness of the item to be laminated has a major effect on the integrity of the bond. Thicker items soak up essential temperature from the laminating nip and if the nip is not thoroughly heated will affect the bond strength. - Page 21 CAUTION : Do not run the film remnants through the machine, always reverse film out of the machine. It is very difficult to cut remnant film webs in such a way that both film ends match. If the unmatched webs are run through the machine the tails will coat the laminating rollers with adhesive and require lengthy cleaning.
- Page 22 Fig 9.3 CUTTING BOTTOM WEB Switch to "Reverse" Holding the loose web firmly, reverse the film out of the machine, assisting its path by pulling towards you. (See Fig 9.4). Fig 9.4 REVERSING FILM OUT...

Page 23: Preventing Wrap Around
9.10 Preventing Wrap-Around When laminating with massive imbalance in film tension or with thinner gauge films, there can be a tendency for the finished laminate web to wind back up as it exits the rear pull rollers. This may happen to the degree that it could curl over and back onto itself and wrap around the rear pull rollers. To minimise the occurrence of wrap-around make sure the laminated web does not curl back on itself, especially when tensioning newly loaded film. -
Page 24: Cleaning
CLEANING 10.1 Cleaning The Nip Rollers With the machine at full laminating temperature and with no film through the machine. Rotate the rollers in reverse to avoid fingers or rags being dragged into the nip. Use a kerosene-soaked cloth, to rub the adhesive build-up line until it evaporates. -
Page 25: Manufacturers Recommendations
MANUFACTURER'S RECOMMENDATIONS 11.1 Film Types This machine has been specifically designed to run the low temperature co-polymer films. WARNING : It is strongly advised that lower quality monomer (Regular) grades of laminating films are not used. The excessive temperatures, high tensions and pressures these low quality films require to produce a result will produce excessive wear and tear on your laminator. -
Page 26: Laminating Tips
LAMINATING TIPS 12.1 De-Curling The sheet to be laminated needs to be generally flat and wrinkle free. Many items to be laminated are supplied to you in a rolled up form, this can cause feeding difficulty if the leading edge curls up leading into the laminating nip. -
Page 27: Fault Finding
FAULT FINDING 13.1 Poor Film Adhesion Problem: Material not laminating or laminating in patches. Nearly all instances of poor lamination adhesion is due to a lack of heat or pressure at the laminating nip. Possible Cause Lack of heat in the nip roller due to insufficient warm up period and/or lack of nip roller rotation during warm-up. -
Page 28: Lack Of Edge Seal Down
13.3 Lack of Edge Seal Down Lack of edge seal is the result of insufficient down pressure from the nip rollers. Possible Solution The article being laminated is too thick to achieve a satisfactory seal (See Section 9.5, Thick stock, Page 15). -
Page 29: Film Shrinkage
Possible Solution Remove film after use and clean machine. 13.7 Film Shrinkage Problem: Film shrinks or narrows from its original width during lamination. Excess tension and/or heat, especially with 1.5mil films. Possible Solution Reduce film tensions and if necessary reduce temperatures. 13.8 Undulations in Laminate Problem: The finished lamination has a "wave"... - Page 30 Warranty does not include damage due to operator error or general maintenance. When necessary, purchaser shall properly pack and return the unit to the nearest USI Service Center, freight and insurance prepaid.
