Abstract

A method for producing an electric strip laminate wound into a coil is disclosed, in which at least two metallic electric strips that are electrically insulated from each other are integrally bonded to form an electric strip laminate and in another step, are wound into a coil. In order to ensure a reproducible method, the invention proposes that the electrical strips, which are each electrically insulated on at least one flat side with a baked enamel layer, be joined to each other by means of baked enamel layers facing each other and be integrally bonded to form an electric strip laminate by activating the chemical cross-linking of the two baked enamel layers.
