A method for producing an electromagnetic component for an electric machine is provided. The method includes providing a metal sheet as a starting material; punching out a number of lamellae from the metal sheet; heat-treating the lamellae; and joining the heat-treated lamellae to form the component or a portion of the component. The electromagnetic component to be produced can be a laminated core, for example a stator core or a rotor core, and can be provided for use with the electric machine such as an electric motor.

The invention relates to a method for producing a lamination stack, e.g. a stator package or a rotor package. The method comprises the following steps: A) providing a metal sheet () with an adhesive coating; B) transporting the metal sheet in an in-line system comprising a cutting means (), a separating means () and an activation means (); C) cutting a molded part () with the cutting means (); D) activating the adhesive coating; E) separating the molded part (); F) placing the molded part (); G) repeating steps C) to F), wherein the adhesive coating of some molded parts () is provided with a treatment fluid by means of a treatment device () in order to allow for target breaking points for separating a molded part stack ('). In some cases a subsequent compaction can be carried out by a compaction station (). The invention also relates to a lamination stack and an electric machine.

An apparatus and a method for the treatment of a flat steel product, taking place in throughput. The apparatus includes an indirectly heated annealing furnace chamber, a conveyor device for continuously conveying the flat steel product over a conveyor path leading from an entry to an exit of the annealing furnace chamber, and nozzle arrangements for feeding atmosphere gas, which is reactive in relation to the flat steel product, into the annealing furnace chamber. A controlled treatment of the flat steel product includes a first nozzle arrangement, from which a gas jet induces a first gas flow towards the entry of the annealing furnace chamber and sweeping over the surface of flat steel product to be treated. A second nozzle arrangement includes a gas jet which induces a second gas flow directed towards the exit of the annealing furnace chamber and sweeping over the surface of flat steel product.
