The machine is not turned off or shut down. The rolls are programmed to turn/rotate at certain speeds so the desired end product is satisfactory and so the fibers don't break or wrap up. Speeds of the rollers at roll station 1 were programmed to be 96 feet per minute (fpm). There is an interlocked physical safety gate/door at roll station 1
