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.

Abstract: Provided is a method of manufacturing laminated steel plates by laminating a plurality of steel plates, the method including an application process of applying an adhesive agent on a surface of each of the steel plates, and a lamination process of laminating a steel plate, to which the adhesive agent is applied, and another steel plate while shifting positions of the steel plates about an axis with each other, and causing the steel plate to adhere to a laminated body using the adhesive agent, wherein, in the application process, the adhesive agent is applied such that the adhesive agent becomes in a shape that is continuous about a central axis when the steel plate and the other steel plate are adhered by the adhesive agent in the lamination process.
