Abstract

For the production of a plate packet for magnet cores that have an opening in the longitudinal direction of the plate lamellae, inner plate lamellae with reduced cross-section are stacked in the region of the opening. Of these inner lamellae, at least two lie in one plate plane and together have a surface that is reduced in size by the cross-section of the opening in comparison to the size of the outer plate lamellae.
