Abstract:
An apparatus for fabricating a laminated core includes a lower mold including a die including a die hole, an upper mold including a punch, a stripper plate operable to restrict upward and downward movements of a metal sheet at a lowest descending position during punching out of the metal sheet by the punch, an adhesive applicator included in the lower mold and operable to apply an adhesive onto a lower surface of the metal sheet, and a controller configured or programmed to control the stripper plate and the adhesive applicator. The controller is configured or programmed to include a movement controller to control upward and downward movements of the stripper plate, and an applicator controller to cause the adhesive applicator to apply the adhesive onto the lower surface of the metal sheet while the stripper plate is not located at the lowest descending position.
