PURPOSE: To enable overlapping part at the junction part of each core block to be retained exceeding a specified size by eliminating one unit laminated body every time a specified number of laminated body blocks are formed at a process for forming the laminated body block.
CONSTITUTION: When forming each laminated body block 9a of n unit laminated bodies 90. one unit laminated body 90 is eliminated when specified number of laminated body blocks 9 consisting of n unit laminated bodies 90 are formed and then the laminated body block 9 is formed by n unit laminated bodies 90. Thus, the average length of the laminated body block 9 formed after eliminating one unit laminated body 90 call be made longer than that when one unit laminated body 90 is not eliminated. It allows the overlapping part of the core block to the original size and can maintain the overlapping part of the junction part of each core block exceeding a prescribed size.
