ABSTRACT:
A method and apparatus for selectively removing target sections from a continuous coil of sheet metal and connecting those sections to one or more sheet metal take-up winders. Depending upon the thicknesses or amount of defects in each detected target section, the corresponding target can be connected to an appropriate continuous sheet metal winder which therein contains a specific classification of sheet metal. Defects, such as errant sheet metal thicknesses, can be removed from a continuous coil and placed on a raw sheet metal coil separate from a finished sheet metal coil containing substantially no defects.
