If the film curls up as it leaves the machine, loosen the top supply roll
mandrel (turn counterclockwise) and/or tighten the bottom supply roll
mandrel (turn clockwise).
If the film curls down after it leaves the machine, tighten the top supply roll
mandrel (turn clockwise) and/or loosen the bottom supply roll mandrel (turn
counter-clockwise). In making these adjustments, make sure that top and
bottom supply roll tension are kept about equal.
8. When running films of 3 mil or above turn the fans on before beginning to
laminate. “Waves” or “ripples” tending to run through the center of the
laminated web are usually caused by forgetting to run the fans or setting too
high a temperature for the film being used.
“Heat wrinkles”
are formed when the film as not cooled enough before
coming out the back of the machine. For the best results the film should be
cooled below melt temperature while it is pulled tight and perfectly flat
between the laminating rollers and the pull rollers. If it gets out the back of
the machine while still at or above melt temperature heat wrinkles can form.
The major reason for fans on a laminator is to cool the laminate not to cool
the machine.
9.
This machine is equipped with a directional switch:
forward/neutral/reverse. Turn to the forward position to laminate, or to
reverse as required. The manufacturer recommends the stop switch be used
to stop the laminator rather than the neutral position of the directional switch.
To remove anything which may become lodged between the rubber
laminating or pull rollers, remove the feed tray assembly and open rollers.
Switch control to reverse if required.
10. A unique feature of the laminator is the provision for driving both top and
bottom pull rollers and laminating rollers. This feature provides an even
distribution of heat on a continuous basis to the laminating rollers prior to
startup or when laminating production is temporarily halted.
The laminator becomes capable of accepting thick materials, without roll
slippage because the top and bottom rollers are driven. Driven rollers also
minimize the “curling effect” in the finished lamination by providing balanced
power to the laminating and pull rollers.
11. The laminator is designed to operate with the operator directly facing the
control panels and feed tray assembly.
For operator safety the feed table/heat shoe guard, an integral
component of the feed table assembly, MUST BE IN ITS
DESIGNATED POSITION when the temperature of the heat shoes is in
