5 .3 Threading for Projection Operation
5 .3 .1 General Threading
• Put the full reel on the upper reel
shaft or prepare the platter system.
• Open the sprocket pad shoe.
- Thread the film in the feed
sprocket
(all perforations engaged in
sprocket teeth).
- Close the pad shoe.
• Thread the film in the film gate.
- Close the film pressure skate.
- One whole frame must be centred
vertically in front of the aperture
opening. There is a small light
inside the aperture to assist in
centring.
- Assure the film is centred
horizontally between the ceramic
discs.
A film loop of about 4 frames - 16 perforations (35 mm film) must be left both just
above and just below the gate! If the loops are too big the film will touch station-
ary parts and be scratched . If the loops are too small the film may break, the im-
age may jump, or the sound may warble .
• Thread the film through the guide rollers to the sound head (35 mm film) and then to
the bottom sprocket. The sound pressure roller may be lifted to ease threading.
• Open the sprocket pad shoe.
- Thread the film in the holdback/bottom sprocket (all perforations engaged in
sprocket teeth).
- Close the pad shoe.
- Verify the loop below the gate is still OK.
• Wind-up the film several times around the take-up reel or lead film to “take-up” level
of platter system.

NOTE
Z When operating the projector with the handwheel, do not jerk (quickly twist) the
handwheel; instead start its rotation gently and smoothly. Abusing the handwheel
can break teeth from the lower CSS shaft’s fibre cog.
Z If a DTS reader is installed, the film has run from the top of the spool - spool turns
right.
