1. An apparatus for fabricating a laminated core in which a plurality of iron core elements are laminated and bonded to each other, the apparatus comprising:
a lower mold including a die including a die hole;
an upper mold including a punch corresponding to the die hole;
a stripper plate included in the upper mold and movable downward to a lowest descending position that is a lowermost position, the stripper plate being operable to restrict upward and downward movements of a metal sheet during punching out of the metal sheet by the punch;
an adhesive applicator included in the lower mold, located below the metal sheet, 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; wherein
the lower mold includes a lifter to push the metal sheet upward and move downward when the metal sheet is pushed downward by the stripper plate; and
the controller is configured or programmed to include:
a movement controller configured or programmed to control upward and downward movements of the stripper plate; and
an application controller configured or programmed to cause the adhesive applicator to apply the adhesive onto the lower surface of the metal sheet only while the stripper plate is not located at the lowest descending position.
