Size the coil loop and feed slack between the straightener and feeder to keep material tension-free.
A slack loop between the straightener and the feed decouples the heavy coil from the precise feed motion. Too little loop puts tension on the feed and snaps stock; too much drags the floor.
Size the loop pit so it always holds enough slack for the feed to pull freely at full speed.
Formula: Loop must hold ≥ one feed progression of slack at all speeds
