To remove a film loop:
- Place GAM FILM/FX loop machine onto a
level surface with the
Motor on the right hand side.
- Lift the top Hatch Cover A up until it
springs upwards.
- Lift the Loop Tension Door B upwards
until it springs open.
- Lift the Motor and Upper Roller C
forward out of the Loop
Carrier.
Frame D and slide out from inside the Film Loop (left to right).
* Be Careful that the brass end stops don't catch on any Film Loop image
details.
- The Lower Roller will slip out of its
locating slots as the Film
Loop is removed.

To insert a film loop:
- Place the Lower Roller E inside the Film
Loop.
- Locate the Lower Roller E in its slots F
on the bottom of the Loop
Carrier Frame D .
- Draw the Film Loop towards the top of
the Loop Carrier Frame D.
- Insert the Upper Roller into the Film
Loop ,with the Motor on the
right hand side.
*Careful the brass end stops don't catch on any Film Loop image
details.*
- Lower the Upper Roller and Motor
Assembly into retainer
slots,ensuring
the Motor Locating Pin G is on the top.
- Lower the Loop Tension Door B onto the
loop gently.
- Lower the Top Hatch A.
- Apply power to the Film/FX machine to
check that the Film Loop moves
correctly.
- Insert into the Iris slot of the
appropriate fixture and focus as
required.
- Direction can be reversed by changing
the position of the GAM Film/FX in the

Tips for using the GAM
Film/FX
It is important to smooth focus the field of the ellipsoidal spotlight
before inserting the GAM Film/FX into the gate. Hot spots will cause uneven
wear on the Film/FX loops and shorten their useful life. Be sure that the
field is as even as possible with no hot center. Always have the Film/FX
loop in motion before the light comes on. Do not allow the Film/FX loop to
be still in the gate as this will allow one section to heat up and shorten
the life of the loop particularly if the excessive heat is focussed on the
seam.
Tips for improving FX/Loop life
- The FX/loops are delicate. The designs are etched in a 2/1000” thick stainless steel. Please handle with extreme care. Do not wrinkle, crinkle, bend, or fold in any way that might create friction points when it is used in the Film/FX™.
- Be careful when placing it on the drive rollers, see that it is positioned squarely between the brass guide edges of the drive roller.
- There is a precision welded seam on the FX/loop. Check that seam when you get a new one. If the seam of a new loop is separated, the loop may be defective. This will be a wear point and will shorten the loop life.
- One way to increase loop life is to observe the overlap and place the loop in a way that ensures that the seam does not overlap in the direction of travel as viewed from the back of the unit. That may cause the raised edge to rub against the metal edge. (See drawing.)
