Cooling Fans
The cooling fans on the Premier 4 are used during lamination with 3-mil, 5-mil, 7-mil,
and 10-mil film. The fans cool the plastic as it leaves the laminating rollers and before it
enters the pull rollers. As mentioned earlier, the fans prevent heat wrinkling and help
insure lamination that is
smooth and flat. The pull rollers on a Premier 4 turn a little
faster than the laminating rollers, insuring that the film is perfectly flat while it is being
cooled.
NOTE:
It is possible that variances from recommended temperature settings may be
necessary due to material thickness, ambient temperature, humidity, or the quality or
thickness of the material being laminated.
Please note the wide range of temperatures listed, especially for heavier films. This
does not mean any film that thick can be run anywhere within the given range. There
are “standard” (high-temperature) and ‘low-melt” (low-temperature) versions of all film
thicknesses. Some low-melt films work at lower temperatures than others. It is
important you buy your film from a vendor who can tell you the following information
about any film you choose:
•
the thickness
•
the clarity
•
suggested melt-temperature range
•
polyester/polyethylene content
•
how well the adhesive will stick to the kinds of images you’ll be protecting and
enhancing
Temperatures may exceed 300º when laminating poster board or other thick items with
1.5-mil film on a continuous basis, but when the machine is stopped, turn the heat off if
the setting is in excess of 310º.
Never set the heat above 300º with film in the
laminator. Temperatures over 300º are not needed except with special use films.
Film that is 3 mils or thicker is generally run at 280º or less.
Special Note when using 10 mil films:
The Premier 4 is capable of laminating 10-mil films but is not designed as a
continuous 10-mil production machine. Allow occasional cooling off periods
when using film this heavy.
