ABSTRACT:
An amorphous magnetic core is arranged to be obtained by cutting a plurality of amorphous sheets to have a predetermined cut length by a cutter device and supplying the cut sheets to a rectangularly forming device, the sheets being supplied from an uncoiler device including a plurality of reels around which the sheets are wound, by winding the sheets of a predetermined number around a forming mandrel successively to form them into a rectangular shape, thereby forming the magnetic core, and by subjecting the magnetic core to magnetic annealing in an annealing device.
