!!!THE FAN SWITCH MUST REMAIN IN THE OFF POSITION WHEN THE ROLLERS ARE
STATIONARY!!!
Failure to turn off the fans while the laminator is in an idle state will result in abnormal roller cooling,
especially on the bottom roller. This may show as cold spots (foggy areas perpendicular to the film path)
or failure of bottom lamination. To remedy this either:
I. Allow the rollers to stabilize by gaping the rollers and leaving them undisturbed in this position for
5-15 min (with fans off)
II. In extreme cases shut down the laminator (see shutdown, page 58) and allow the machine to cool to
room temperature and then reheat.
III. In minor cases, the rollers may be stabilized by very slowly running film through until the cloudy
spots disappear. This however, may not be an economical solution.
Mounting:
It may be desirable for heat activated foam board to cool under pressure which would mean you would
have to turn the fans off and allow the rear rollers to cool the adhesive when the board contacts them
Speed:
Speed is a function that is very much related to roller temperature, paper temperature, room temperature,
laminate thickness or paper thickness however, several guidelines may help.
- Typically when the film is cold it is somewhat foggy and when it heats up to temperature it
becomes clear while laminating, a good guideline for general lamination is to watch the film as it
comes over the roller, it should become clear before it hits the nip on the laminating rollers
-
The thicker the film the slower the speed-
- The higher temperature rating of the film the slower the speed -
-
The thicker the paper the slower the speed -
- Foam board – keep the machine running very slowly possibly 1-3 feet per minute depending on
your model –
