Claim:
A method of surface inspection of strip pieces ( 120 ) cut from a metal strip ( 210 ), characterized in that the strip pieces ( 120 ) have a length less than twice a circumference of a work roll ( 230 ) with which the metal strip ( 210 ) was rolled previously; upper and/or lower side of the cut-off strip pieces ( 120 ) is automatically checked with the aid of a camera system ( 150 ) and an analysis unit ( 300 ) in regard to any periodic types of defects that may be present which were caused by the work roll; the surface inspection process ends if periodically occurring types of defects are detected, or; the cut-off strip pieces ( 120 ) are fed to a strip inspection unit ( 140 ) for checking by inspection personnel for non-periodic types of defects if no periodic types of defects were detected previously.
