Abstract

PURPOSE:To obtain a laminated core in high accuracy without increasing the steps by forming a projection in response to the deviation in the thickness of a laminated core piece at the thin part to the reference part, thereby making the effective thickness uniform and simply correcting the thickness of the plate at the laminating time. CONSTITUTION:When a laminated core piece 20 is punched from a strip core material 2, a projection 3a of height delta responsive to the deviation in the thickness of the plate is formed at suitably positions 2c-2d of a thin side 2a of the material 2, and the effective thickness of the piece 20 is uniformalized to be laminated. In this manner, the influence of the deviation of the thickness can be eliminated, thereby inexpensively producing a laminated core in high accuracy.
