• Put the full reel on the upper reel
shaft or prepare the platter system.
• Open the sprocket pad shoe.
- Thread the lm in the feed
sprocket (all perforations engaged
in sprocket teeth).
- Close the pad shoe.
• Thread the lm in the lm gate.
- Close the lm 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 lm is centred
horizontally between the ceramic
discs.
• Thread the lm through the guide rollers to the sound head (35 mm lm) and then to
the bottom sprocket. The sound pressure roller may be lifted to ease threading
• Open the sprocket pad shoe. Thread the lm in the holdback/bottom sprocket (all per-
forations engaged in the sprocket teeth). Close the pad shoe. Verify the loop below
the gate is still OK.
• Wind-up the lm several times around the take-up reel or lead the lm to the “take-
up” level of the platter system.
If the projector was switched off with a threaded lm the lm loops and the lm position
must be checked when the projector is switched on again.
