Center each supply roll on the shafts by doing
the following.
Use a ruler to measure the distance
between the left edge of the roll to the
brake hub support.
Measure the distance between the right
side of the roll to the bearing support
side. Shift the roll side to side to ensue
that it is centered on the shaft.
It is important that the edges of the films
are aligned so that adhesive does not get
on the rollers.
Center the take-up core on its shaft.
Adjust the brake tension of the supply and take
up shafts if necessary.
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. The take up roll should
keep the release liner tight without excessive
pulling.
Refer to the Film Tension section in this chapter
for more information.

To load films onto the supply shafts:
If the supply shaft is on the laminator, remove it
by lifting the right end out of its bearing cradle
and then pull the hex end out of the left side.
This applies to the top and bottom supply shafts.
Slide the new roll on to the shaft and core
adaptors, referring to Fig. 6-2 to determine how
the film unwinds from the roll.
Tip: Twisting the shaft in the opposite direction
as the grippers point as you push the roll makes
it easier to insert the shaft.
Use the set screws in the core adaptors to move
the adaptors if needed. They should be out
towards the ends of the film roll. The grippers
on the core adaptors should be pointing in the
opposite direction that the film unwinds from the
roll. See Fig. 6-6.

Insert the hex end of the shaft into the brake hub
on the left and then set the bearing end in its
cradle.
