I have seen MP film on Estar destroy a camera during a run at high speed. This was 35mm in a 1000 ft roll running at such a high speed that the entire roll was used in less than 1 minute. During the jam it tore the teeth off the sprocket wheels and bent the drive shaft rather than break.
Can you imagine what a jam would do to a coating machine at 1000 ft / min? It can bend the entire machine out of alignment.
