Abstract: Conveyance system for tensioning in order to post-treat a rapidly-solidified metal strip, and post-treatment method is provided. The invention relates to a conveyance system (1 to 5) for tensioning in order to post-treat a rapidly-solidified metal strip (6), and a post-treatment method. For this purpose, the conveyance system comprises a tension roller assembly (6 to 11) and a tensioning assembly (12), between which the metal strip (6) is conveyed in order to be continuously post-treated under a predetermined tensile stress. The tension roller assembly (6 to 11) comprises a single drive roller (13) and a freely-rotating pressing roller (14). The metal strip (6) is conveyed over an angle of wrap ? on the drive roller, and, with respect to the drive roller (13), the pressing roller (14) is arranged at a contact point (16) of the metal strip (6) that defines one end of an angle of wrap ?.

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.
