To be fair, punch machines are _terrifying_, and the stories about why anti-tie-down circuits exist just make me cringe thinking about it. Again, operators are immensely clever, and, well, many consider safeties an inconvenience. And then they bring their cleverness to bear on it and someone loses a $BODY_PART$. As for your patent, I'll raise you a "but the patent doesn't cover a _five_ blade fan pointed at a _fifteen_ degree declination at the conveyor", with this leading to a new patent. Technically, that's what patents are all about, but it sure seems silly written out like that. But you're right, that's what happens.
