Which component helps keep the film flat across the frame by seating it against the surface of the gate?

• A. Intermittent Mechanism
• B. Pressure Plate
• C. Film Loop
• D. Gate

Answer: (B)

Keeping the film perfectly flat across the frame hinges on pressing it firmly against the gate’s surface so that every frame lies in the same plane during exposure. The pressure plate sits right over the film inside the gate and is spring-loaded to apply uniform downward pressure. This seating prevents the film from bowing or curling and ensures the image stays in sharp focus from edge to edge while also keeping the perforations properly registered with the gate window. The gate defines the exact opening for the frame, while the intermittent mechanism and film loop handle timing and transport; they don’t actively press the film flat against the gate. So the component that does this crucial seating and flattening is the pressure plate.
