The process begins with loading a coil of steel or master coil onto the uncoiler. The uncoiler can be a dual cone type for heavy gauges or a single end expanding mandrel type for heavy or light gauges. The coil can be loaded into the cones via a pusher type ramp or via a turnstyle and coil car that threads the mandrel of the single end into the inner diameter of the master coil.
The hold down presses onto the outside diameter of the master coil and the bands are cut on the master coil. The coil is rotated off the cones or mandrel and peeled to allow the head of the coil to enter edge guides prior to the flattener and leveler (if flatness is critical in downstream operations). Next, The slitter, which consists of two parallel arbors mounted with rotary cutting knives.
