Abstract

A continuous strip method for producing an electric strip laminate which is wound into a coil is proposed in which at least two electric strips are pressed against each other on their flat sides and are integrally bonded to form an electric strip laminate and in a further step, this electric strip laminate is wound into a coil. More particularly, a first electric strip is coated on at least one of its flat sides with a first thermally activatable hot melt adhesive lacquer, the first hot melt adhesive lacquer on the first electric strip is thermally activated, and then the electric strips are pressed against each other on their flat sides with the activated first hot melt adhesive lacquer layer between these flat sides and a second electric strip is supplied to this pressing process at a temperature below the activation temperature of the first hot melt adhesive lacquer layer on the first electric strip.
