Abstract
In manufacturing a laminated iron core by laminating and bonding iron core laminates blanked from a sheet steel strip into a prescribed profile, the adhesive agent can be applied to the iron core laminates in a stable manner without regard to the arrangement and the number of the application spots on each iron core laminate. The metallic die machine (1) is provided with an adhesive agent application unit (12) configured to apply an adhesive agent to a prescribed area of the sheet steel strip (W) corresponding to the iron core laminates (2), and the adhesive agent application unit is provided with a casing (44) defining a plurality of adhesive agent storage chambers (55-57) for storing the adhesive agent before the adhesive agent is applied to the prescribed area. The casing is provided with a plurality of ejection orifices (H1 to H3) each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent.
