Abstract

PURPOSE:To obtain the punched out cores having the uniform thickness of a laminated layer by a method wherein the convexed section to be used for correction of the deviation of a plate thickness is formed on the surface of said cores. CONSTITUTION:The convexed section 5 equivalent in height to the deviation of the plate thickness 4at-4bt is formed on the left side 4b of the punched out cores 4. Then, a core is formed by laminating a plurality of the punched out cores 4. Through these procedures, the uniform cores can be obtained without making a rotation at an angle of 180 deg. or an inversion at the intermediary stage of the core laminating process.
