Supply boxes for presses 21 to 24. Aug 19 night shift, 10:55 pm. Camera 9.
A torn pellet bag on a supply box just after the jam
What it shows: Five minutes after the jam, a torn, empty pellet bag lies on one box and presses 23 and 24 are still running.
Why it proves the point: The jam came before these presses stopped, so it began at the supply, likely with a strip torn from this bag.
