Abstract

In a method for producing a lamination stack for rotors and/or stators of electric motors or generators, laminations are punched from electrical steel, a light-activated adhesive is applied to at least one side of the laminations, respectively, and the adhesive is irradiated and activated with a light of a required wavelength immediately before the adhesive exits from an application unit. The laminations are then stacked to a lamination stack. An adhesive application device for carrying out the method has at least one application unit with at least one valve for discharging an adhesive. At least one radiation source is arranged in a region of the valve and emits a radiation and directs the radiation to the adhesive provided in the region of the at least one valve.
