Abstract
A metal processing apparatus comprises a scale breaker apparatus having a plurality of rollers positioned in a staggered arrangement and engaging first and second surfaces of sheet metal. The staggered arrangement creates clearances between the rollers of the first and second surface rollers sufficient to enable the sheet metal to conform to a portion of an outer periphery of at least one of the rollers while passing between the first and second surface rollers under a tensile force. The metal processing apparatus further comprises a recoiler adapted to coil the length of sheet metal. The recoiler subjects the sheet metal passing through the scale breaking apparatus to a tensile force sufficient to conform the sheet metal to a portion of the outer periphery of at least one of the rollers with a wrap angle sufficient to break scale from the sheet metal.
