I work maintenance in a roll mill and this is a common occurance, maybe an average of 3 or 4 times in a 12 hour shift, depending mostly on what size is running. The smaller the product the harder it is to get it to the end, the difference between pushing a broom stick or a spaghetti noodle. Every set of rolls it goes through reduces it's diameter by maybe 10 to 20 percent, but that material has to go somewhere, so it grows in length. Which means it also picks up speed by that same 10 to 20 percent every millstand it goes through, in our mill there's 18 millstands. The 5-1/2" billet enters #1 at about 2 mph and exits #18 as a 180' long railroad spike 1600 degrees travelling about 40+ mph. So as you can imagine that it doesn't take a much of problem to cause a cobble. I would guess that an average cobble takes about 30 min to clean up and get back to running, not a very fun part of the process.
