Orca 80-99 Operation and Maintenance Manual
4.
Center the film by sliding it back and forth on the
shaft until centered. As soon as the film is unwound
from the shaft, the core support will lock the roll into
position.
5.
Recheck the centering of the film roll with a tape
measure.
WARNING:
Normal operation of the Orca 80 laminator
involves the application of large amounts of heat
to the process materials. The surfaces of the rolls
are at a high enough temperature to cause burns if
they are touched.
Operators are cautioned not to touch, lean or fall
against the rolls of an operating laminator. Do not
become unbalanced when working near an
operating laminator.
Heating
The following instructions should be employed when
heating one or both of the laminating rolls. The
procedure is the same for top and bottom:
1.
Set the heater switch to
ON
.
2.
Adjust the temperature controller for the desired
operating temperature using the controller push
bottoms.
For the Syrlec type controller use the up and down
arrows to adjust the set point. Hold down the desired
arrow until the correct set point is achieved.
For the CAL3200 it is necessary to press the
*
button
at the same time as the up or down arrow to adjust the
set point temperature.
3.
When heating the rolls, keep the top roll down and
turning at a moderate speed to prevent uneven heating.
4.
It will take approximately 25 minutes for the
laminating roller(s) to reach operating temperature.
When the pre-set operating temperature has been
reached, the machine is ready to use.
Cooling
(with optional cooling fans)
The following procedure is the fastest way to cool
down the machine. Natural cooling can also be
employed:
1.
Set the heater switches to
OFF
.
2.
Position the two rear fan banks so that they are tilted
to direct air flow at the rolls.
3.
Set the Laminator Roll Control to the
DOWN
position.
4.
Set the Forward/Reverse switch to the
FORWARD
position.
5.
Set the speed control to 5 fpm (150 cpm).
6.
Let the machine run until the laminating rolls return to
room temperature.
Paper Tips
1.
Always cut the leading edge of a print straight so they
can be fed perpendicular to the laminating rolls.
Process Control Charts
Chart 2-1 and 2-1B show a blank set of process
control charts for the ORCA 80. These charts are
where you record the way you thread film through the
machine’s rolls and idlers (called webbing) and the
setting of controls and switches for each product and
process.
GBC Pro-Tech laminators respond in a very accurate
and repeatable manner. The charts provide a way to set
up each time, every time, for repeatable performance
by assuring all controls are set to optimum.
