FILM TENSION ADJUSTMENT
Proper film tension, known as brake tension, is the mini­
mum amount of tension required to eliminate wrinkles in
the finished item. The film tension is set at the factory.
Periodic adjustments should not be necessary unless
other than 1.0 or 1.5 mil GBC film is used or the lamination
is curling up or down. Film tension may be checked occa­
sionally to assure that the adjustment is not required.
The film should be taut. A properly adjusted roll of film
should not require excessive force to turn by hand. Film
tension should be enough to introduce a minor amount of
drag as the film unrolls. Insufficient tension cause wrinkles
while too much tension causes stretching (necking).
Uneven tension between the top and bottom rolls create
curl. Too much upper tension creates upward curl while
too much bottom tension causes downward curl.
1. To adjust the bottom brake. Push and hold the brake
lever, (Figure 11), located on the left side frame by the
roll of film. Rotate the roll of film until the lever engages
the internal mechanism.
2. Refer to Figure 10 for the proper rotation of the film to
increase or decrease the tension.
3. Release the brake lever and check the tension by rotating
the roll of film. Resistance should be slight, not forced.
4. To adjust the top brake repeat steps 1 through 3.
5. Laminate some test samples to check for proper tension.
Further adjust if necessary.
CLEARING A FILM JAM (Wrap-up)
Film jams (wrap-up) may occur if the film is loaded on
backwards or if the area at which film exits the equipment
is blocked. The film, when jammed, wraps around heat or
pull rollers. To clear a jam it is necessary to rotate the
rollers in the reverse direction. When pressed, REVERSE
® on the control panel will cause the rollers to go in
reverse. To clear a jam:
1. Immediately stop the laminator by pressing STOP |@1.
2. Set the speed indicator to 2.
3. Raise the safety shield and remove the feed tray.
4. Cut the top and bottom film webs.
5. Grasp the loose ends of the web, pull straight out,
install the feed tray so the web is on top of the tray.
Lower the safety shield, press REVERSE Sl and guide
the film out of the heat rollers.
6. Once the jam has cleared the heat rollers press
STOPl^.
7. Thread the film per section FILM LOADING & THREADING.
SPEED GUIDE AND THE ART OF LAMINATION
Do not attempt to laminate abrasive or metal objects
such as staples, paper clips and glitter as they may dam­
age the heat or pull rollers.
Do not force items into the nip area of the heat rollers.
An item that is not easily drawn into the laminator by the
heat rollers is probably too thick to laminate.
Wrinkles may result if an attempt is made to reposition an
item once it has been grasped by the heat rollers.
Do not stop the laminator before an item has completely
exited the pull rollers. Even a momentary stop will cause
a mark (heat line) on the laminated item.
Good, consistent lamination is a result of combining proper
heat, tension and dwell time. Dwell time is the amount of
time the material to be laminated is compressed between
the heat rollers and is control by the speed control. When
one of the film gauge buttons is selected the laminator
automatically sets the speed and temperature for that film
and 20 lb. paper.
As a general rule thicker items and films as well as dark or
full ink coverage, need to run at slower speeds because
they extract more heat from the rollers at a quicker rate.
Setting the speed control at slower settings gives the lami­
nator longer dwell time thus allowing proper lamination of
thick items. Thinner items, such as standard copier paper
(20 lb. bond) and tissue paper, extract less heat from the
rollers and can be run at faster speeds.
The WAIT E3 lamp may illuminate if the speed is set too
fast for the material being laminated. Either lower the
speed setting or press STOP ^ and wait until the READY
Olamp illuminates.
Operation of the laminator for more than thirty minutes at a
time may necessitate a lower speed setting. It is recom­
mended that during periods of long runs the items being
laminated are alternated between thick and thin. Do not
combine thick and thin items at the same time as this will
result in a poor edge seal around the thinner material. If
you are unsure that the laminator is set at the proper
speed for your item, run a test piece (scrap) of the same
or similar material through the laminator. This procedure is
recommend because rotating the heat rollers prior to lami­
nation will more evenly distribute the heat. Make speed
adjustments as necessary.
The following chart provides general guidelines for proper
speed settings to use on certain materials and laminating
film combinations. This chart is only a general guide.
Different settings may become necessary as the warm up
time, lamination time and materials change.
