THREADING
Threading the projector correctly is one of the operator’s most important duties. Careful attention
during this operation pays off in improved performances and long print life.
Unlatch and open the turret. Rotate the framing handle (A)
to position the intermittent sprocket (B) at the center of its adjust-
ment range. Using the motor flywheel, turn the mechanism by
hand to rotate the intermittent sprocket (B) to its “rest” position.
In the “rest” position, the intermittent sprocket is in a locked,
stationary stage while the other sprockets continue to rotate.
Open the feed (C) and holdback (D) sprocket pad roller as-
semblies. Open the film gate by pulling the gate opening pin (E)
and sliding the film gate forward to the threading position. Open
the intermittent sprocket roller arm (F).
At this time, it is advisable to dismount the film gate
pressure pad by sliding the gate to its full forward position, and
loosening the thumb screw (G). Withdraw the pressure pad runner
from the film compartment and use a clean, dry cloth to wipe
down all film-bearing surfaces of the gate and trap. Replace the
pressure pad after cleaning and secure thumb screw (G). This
procedure should be performed at least once every day.
Thread the film as illustrated. Engage first the intermittent
sprocket (B), and check for correct frame position at the lighted
framing aperture (H). When correct, close the intermittent roller
arm (F). Secure the gate by pushing the gate into the trap until the
spring-loaded gate latching pin (E) engages. Form a two-finger
loop above the gate as illustrated, and on the loop chute below the
intermittent sprocket. Draw the film over the impedance drum (I)
and close the pad rollers over sprockets (C) and (D).
Rotate the motor flywheel by hand to advance a few frames of film. Do not “inch” the mechanism by
momentarily switching the drive motor on and off; in the event of a threading error, film may be damaged. Run
fingers over each sprocket (B, C, & D) to insure that the sprocket teeth are centered in the film perforations,
and the film is centered between the flanges of the pad rollers. Check again the position of the film in the
framing aperture (H). With the intermittent sprocket in its “rest” position, a correct frame image in the framing
aperture insures correct frame positioning in the picture aperture and on the screen. Use the framing handle (A)
to correct misframes. Close and latch the lens turret.
A slight degree of film tension is required above the upper feed sprocket (C) and below the holdback
sprocket (D). This measure prevents the film from snapping upon motor start.
