Abstract

An apparatus and method for bonding sheet metal parts to a laminated core in which sheet metal parts are punched from an electrical steel strip, the punched sheet metal parts are stacked and bonded at least integrally to form a plurality of laminated cores, and in order to facilitate the separation of the integrally bonded sheet metal parts into laminated cores, a separating agent is provided at least between two stacked sheet metal parts in that with the punching stage for punching the sheet metal part, the separating agent is both punched from a separating agent support and provided to the sheet metal part. In order to embody the application of a geometrically accurate separating agent in a reproducible and simple way, it is proposed that the separating agent be punched from the sheet-like separating agent support that is supplied below the electrical steel strip.
