Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a product measurement position correction method and a crop part shearing method for a rolled steel plate, with additional information such as crop shape in addition to bending amount, a total length, and a total width of a steel plate taken into account.SOLUTION: The crop part shearing method for a rolled steel plate is characterized in that upon shearing a crop part by using the crop shape information of the rolled steep plate, an horn length is calculated from a valley position based on the crop measurement data of a planar shape meter, and a cutting position is set according to L-L=A (mm), L(mm) being a long horn length, L(mm) being a short horn length, the maximum value CLmax (mm) of a crop length limit, a minimum value CLmin (mm), and a margin α(mm) when the vicinity of the valley is sheared in crop conveyor equipment.
