A quick question regarding poyester film in movie cameras / projectors. Couldn't they mitigate the damage risk of jammed films by using a sacrificial key on the shaft and sprockets? Much the same as props on outboard motors. Any serious jam would shear the key. Disassemble cleanup replace key and away you go again. In more sophisticated applications I thought they would have employed clutches on the shafts which would slip or disengage at preset loads.
Just a thought or two.
