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.
Always laminate some thinner items before starting on thicker items. In severe situations (winter
temperatures) try to warm the items to be laminated with a fan heater.
Edge seals are difficult to achieve on thicker items as the nip rollers are unable to achieve sufficient
down pressure around the edges. Presentation to the client "cut clean" to the edge is accepted as
normal. Learn to identify the weight of stock where edge seal is not practical so that it can be
discussed with your client before laminating.

Fan Control
The fans provide cooling to allow the hot resin to "set" before exiting the machine and avoiding
waves when using "soft" gauge films (this can become more pronounced on continuous run
quantities).
9.7
Temperature Settings
Your laminator should be set at 270 o F during the warm up process to accelerate heat absorption by
the nip rollers.
ONCE WARMED UP THE NORMAL OPERATING TEMPERATURE IS 250 o F
This is the recommended laminating temperature for all 76 micron film.
Do not increase heat excessively (i.e. beyond 270ºF) or it may produce a rippled surface or
bubbling as moisture is released from the paper substrate that is being laminated.
You will only ever need to raise the laminating temperature when laminating 38 micron film (See
11.2, Film Gauges, Page 23).
CAUTION :
Do not run your laminator at 280ºF or above. You run the risk of degrading the laminating rollers.
They will harden and crack with prolonged exposure to high laminating temperatures. They are very
expensive to replace.
9.8
Closing Down
Laminating film may be left in the machine until next required.
(a)
Switch to "STOP".
(b)
Turn off mains.
It is a good practice to occasionally remove film when closing down to facilitate cleaning
procedures.
9.9
Film Removal
The following procedure should be used when removing film remnants when you reach the end of a
supply roll.
