6-3 LOWER LOOP SETTER SYSTEM
A. Description
The lower loop setter mechanism is an integral part of the loading mechanism which is
controlled by the function switch. At the "STOP" position the loop setter gear (9) is raised
up away from the main drive belt. The loop setter arm (1) and the lower loop setter roller (2)
is locked in the down position, functioning as the lower loop former while loading the film.
Rotating the function switch to the "MIC" position, the stop plate (14) is pushed to the left
by the protruding tab of the main interlocking bracket until the loop setter interlocking arm
(5) is released away from the stop plate (14). While the protruding tab on the interlocking
bracket is pushing the stop plate, the film is seated in the #1 sprocket shoe and the film
gate is completely closed. The loop setter roller is then raised up away from the film and
the loop setter gear is lowered into position near the main drive belt. In this position the loop
setter is ready to be activated by any small amount of film pressure against the loop setter
roller. When the loop setter roller is activated, the loop setter gear engages with the main
drive belt, causing the eccentric gear to cycle the loop setter mechanism, pulling down the
film from the gate, thus forming a new loop. In "Rewind" and "Stop" the lower loop setter
roller is locked in position to guide and dampen the tension of the film during high speed
rewind.
