Abstract

Provided are a manufacturing device for a laminated core and a manufacturing method for a laminated core that facilitate the assembly of the adhesive applicator and reduce the time required for maintenance. The manufacturing device 1 for a laminated core 4 according to the present invention includes: an adhesive applicator 6 that applies an adhesive to portions of a steel sheet 2 corresponding to core sheets 3; a reciprocating drive portion 7 that switches whether or not to the adhesive is applied by the adhesive applicator 6; and a buffer member 8 that allows displacement of the adhesive applicator 6 in a reciprocating direction, wherein the adhesive applicator 6 has a discharge portion 60 that discharges the adhesive from a tip of a passage 60a, and when the application of the adhesive is performed, the adhesive applicator 6 is disposed such that the adhesive discharged from the tip of the discharge portion 60 is brought into contact with the steel sheet in response to an up and down movement of the steel sheet 2 accompanying the forming of the core sheets 3 by punching from the steel sheet 2, and the buffer member 8 is configured to adjust a contact pressure of the tip against the steel sheet 2.
