Accumulating strip before the mill

 · For example if the tube mill runs at 100 feet per minute (FPM) (30 meters per minute MPM ) and it requires four minutes to complete the end joining operation 400 feet (122 meters) of strip will be used by the mill while end joining occurs. The accumulator must therefore have a capacity of at least 400 feet (122 meters). A tower can also be used.
