Zusammenfassung:PURPOSE:To improve the inspection processing capability by releasing pinch rolls holding a metal board when an abnormality is detected through an inspection table and cutting the abnormal portion while storing the metal board between a feed roll and the inspection table without stopping the feed roll. CONSTITUTION:When an abnormality is detected on an inspection table 1, an upper pinch roll 4A is lifted and separated from a steel board 2. Consequently, the steel board 2 does not advance into a fixed shear 5 but stops there or stored between a bridle roll 3 and the table 1 while being looped because the bridle roll 3 is rotating continuously. The fixed shear 5 interlocked with the roll 4A cuts off the abnormal portion which is discarded into a crop bag 7. In the process, the roll 4A continues rotation and lowers after the abnormal portion is cut off, then the steel board 2 is held again by the pinch rolls 4A, 4B and carried through the shear 5 to the outside of the system.
