Abstract: Design of the ARRIFLEX 765 65mm camera was a challenging engineering task. This article outlines how a single pulldown claw can accommodate rates of 2 to 100 frames/sec at standard loop adjustment. Development of this pulldown claw involved determining the force rate required and designing a film-transport system having a double-sided, one-toothed registration pin and a double-sided, three-toothed pulldown claw. Picture steadiness of <0.1% of frame height and noise level <25 dBA at 24/25 frames/sec were achieved. Use of ball bearings rather than slide bearings makes the camera maintenance-free for an extended period.
