Abstract

PURPOSE:To cancel the deviation in the thickness of a laminated core for an accurate electric device by inverting desired number of core pieces as much as half in the course of laminating. CONSTITUTION:Core pieces which are punched by a movable punch 15 are sequentially laminated in a rotary die 8 upon downward movement of an upper die unit 2. When the number of the laminated pieces becomes as prescribed, an air cylinder is driven to instantaneously move the punch 15 to the position of the punch 15' while the punch 15' to the position of the punch 15. The die 8 is inverted at 180 deg.. Then, when the number of laminated core pieces in the die 8' becomes as prescribed, the punches 15, 15' are similarly moved, and the die 8' is inverted at 180 deg.. This operation is repeated, thereby forming a core which is laminated and integrated in the prescribed thickness.
