Abstract

PURPOSE:To reduce the man-hour of a blanking process while improving the yield of core material by continuously blanking core plates alternately in semicircle from a belt-shaped core material having a width half the outerdiameter of the intended circular core. CONSTITUTION:The belt-shaped core material 9 having a width half the outerdiameter of the intended circular core is prepared and core plates of semicircle are blanked alternately in a manner opposite to each other by way of a small blanking margin 10a. Accordingly, continuous blanking of core plates can reduce the man-hour of blanking while improving the yield of the core material 9 by a degree equivalent to a lengthwise overlap 11.
