BOTTOM LOADING AND THREADING
1.
Remove the bottom polyofin take up roller shaft.
2.
Remove the bottom film supply roller shaft.
3.
Fit the other spare cardboard tube between the two core supports of the bottom polyofin take up roller
shaft.
4.
Fit the second roll of DRY FILM between the two core supports of the bottom supply roller shaft.
5.
Replace the bottom supply roller shaft with roll of film onto the machine, the round bearing end fits in the
side with the steel spring clip first and the hexagon end fits into the hexagon film tension socket. Ensure
the film roll is loaded the correct way, film dropping off the front of the roll.
6.
Replace the bottom polyofin take up roller shaft.
7.
Adjust the lateral position of the bottom DRY FILM roll to align with the top DRY FILM roll, measure if
necessary from the side plate to the side of each roll to ensure accurate alignment. If these rolls are miss-
aligned then a build up of emulsion from the dry film will be come attached to the silicon front heat and
rear pressure rollers causing problems.
8.
Adjust the lateral position of the bottom polyofin cardboard
tube to align with the dry film roll.
9.
Remove the end of the bottom polyofin film and tread up the
bottom section as per the threading diagram, the bottom guide
idle roller can be easily pulled forward via the curved slots to
allow easy threading ( see diagram ). Stick the edge of the
polyofin film to the bottom take up roller tube with masking
tape across the tube width.
10.
Roll both rolls together to allow excess film to feed upwards
above the heat rolls and feed up behind the safety guard and
back over so to remain in position.
11.
Lift the pressure release lever on the right side of the laminator
until vertical, this separates the rollers, then feed a scrap piece
of board between the rollers forcing both films through the rollers.
12.
Lower the pressure release lever and secure in working
position. See Diagram ( This position is adjustable for
different thickness of panels giving increase roller pressure
the lower the handle ).
13.
Lower the safety guard. ( the guard has two switch
interlocks both ends which inhibit the motor rotation )
14.
Switch the machine on with the ON/OFF rocker switch at
the rear of the laminator adjacent to the mains input cable
entry, the temperature defaults to zero degrees centigrade,
adjust the motor speed on the front panel to No 4 and switch
the motor on with “ RUN”, allow to feed so that the scrap
card exits fully from the rear of the laminator and then stop
the motor with “ STOP”. If during this operation film jam
problems occur then the “REVERSE” button can be
pressed to eject the film and allow this operation to be
repeated.
15.
Re-position the bottom guide roller via the curved slots to the top running position.
16.
At this point some tension should be put onto both the film rolls via the two knobs marked “ TENSION “
at the end of the film roll shaft this is to ensure that when the machine is run the film does not snake and
over run when the machine stops. To little tension will cause creasing to much tension will cause the film
to stretch and break, a good starting point is to slacken the tension knob just from the spring and add two
full turns of the tension knob. This is a good starting point, the tension will also need to be adjusted
between different thickness of films and also different manufacturers of films.
17.
Run off about 1 metre of film to allow creases and misalignment to be corrected.
18.
If both films entry point into the heat rollers are aligned then the laminator is filmed, if not check the
positions of both dry film rolls from the end plates and re-adjust if necessary. Replace the machine table
and align the work feed stop to within 5 mm of the inside edge of the dry film.
The laminator is now threaded with film and ready to run, it is advisable to check with the manufacturer the
recommended laminating temperature of the dry film, the feed speed and the exit temperature required. As
with some Dry Films the peelable POLYOFIN sheet can have a low melting temperature. The guide roller
adjacent to the machine guard which is situated above the top heat roller can get hot. When the machine is
switched off this POLYOFIN film can stick to the cooling guide roller. When next the machine is switched on
and the drive motor activated this POLYOFIN film can break, if this happens then use the alternative treading
diagram on page 5.
