FRAMING TENSION
The amount of tension required to operate the framing lever (I) is adjustable, although a degree of
tension is required to prevent the film from “creeping” out of frame. The adjustment screw (B), held in position
by locknut (A), applies or relieves tension on the nylon tension plug (C). In turn, the tension plug (C) applies or
relieves pressure against the vertical framing shaft (D), regulating the coupler assembly (E). Torque applied to
framing lever (I) is transmitted through shaft (H) and gear (G). Rotation of the vertical framing shaft (D) moves
the coupler assembly on a horizontal plane, changing the frame position of the intermittent sprocket (F).
Framing tension is adjusted as follows:
1. Remove the framing lever and the rear quarter panel (see
“Shutter Timing”).
2. Remount the framing lever (I).
3. Loosen locknut (A) and tighten or loosen adjustment screw
(B) as required.The framing lever (I) should move with
relative ease, however, inadequate pressure on tension
plug (C) will allow film to “creep” out of frame.
4. Re-tighten locknut (A); remove framing lever (I).
5. Replace the rear quarter panel and the framing lever.
INTERMITTENT SPROCKET ALIGNMENT
The intermittent sprocket is secured to the outboard
intermittent sprocket shaft in a manner which permits a slight
degree of horizontal adjustment of the sprocket. This adjust-
ment is facilitated by use of a Studio Guide Gauge available
from Strong International Dealers. Gauge 3567-F (as shown)
is designed for Pro-35 projectors in current production; for
older models (without the lateral stabilizer plate), order Gauge
3568-F.
Place the gauge between the studio guides (A) as
shown. Loosen, but do not remove, screw (C). Slide the
sprocket on its shaft until it is centered on the narrow portion
of the gauge. Securely re-tighten screw (C).
NOTE:
3567-F = 1.377 in. wide
3568-F = 1.375 in. wide
