Johnwalkr had some good reasons. The machines are old, with gears and belts to transfer motion not something made with separate motors for each motion. I never saw the specific machine I am mentioning but I wouldn't be surprised if protective parts of the machines stayed off to make it easier to fix malfunctions. The machines were designed at a different time. I've been in the back of a few alleys as a kid and they seemed a few steps, but not that many, beyond the shops where all tools were driven by belts from the ceiling. For example power looms severely injured people in a time before they were designed with safety guards and that's just moving thread>
