Abstract
A method for connecting lamination parts to form a lamination stack in which lamination parts are stamped out from an electrical strip that is coated with an activatable adhesive layer on at least one of its flat sides and the stamped-out lamination parts are stacked and glued to form lamination stacks, wherein before the lamination parts are stamped out, the electrical strip is embossed in a first sub-region, which produces multiple protruding spacers on at least one flat side of the electrical strip, which spacers, after a first lamination part is stamped out from this first sub-region, facilitate a detachment of the stacked and glued lamination parts into lamination stacks.
