摘要 PURPOSE:To prevent an inconvenience caused by a cutting work from occurring by omitting the cutting work of a coupler provided to hole the positional relationship between pole members. CONSTITUTION:A cross-shaped hole 20a is formed at an iron plate 20 by a punch 36, a cross-shaped coupling member 21a is press-fitted to the hole 20a from a nonmagnetic plate 21 by a punch 37, and the plate 20 is cut by a punch 38. In this case, the plate 21 is pressed by a punch stripper, and the plate 20 is pressed by the lower surface of a middle die 34 by moving the die 34 downward. When an upper die support 35 moves from the bottom dead center upward, and the punches 36, 37, 38 and the plate 21, the plate 20 is fed in the prescribed distance by feed rollers 26a, 26b, and the plate 21 is similarly fed by the feed rollers.
