Abstract
A method producing soft magnetic strip material for roll tape-wound cores with the following steps: preparing a band-shaped material, applying a heat-treatment temperature to the band-shaped material, and applying a tensile force to the temperature-applied band-shaped material in one longitudinal direction of the band-shaped material in order to produce a tensile stress in the band-shaped material, to produce the soft magnetic strip material from the band-shaped material, the method, moreover, comprising determining at least one magnetic measurement value of the soft magnetic strip material that has been produced and controlling the tensile force for setting the tensile stress in a reaction to the determined magnetic measurement value. Furthermore, a device for carrying out the method and a roll tape-wound core produced by means of the method are made available.
