    Abstract: The invention relates to a method for manufacture of a transformer core made of ferromagnetic material, such as amorphous metal or silicon iron, which is provided as a single ribbon layer or as multiple ribbon layers,
    characterized by the following steps
    a) the single ribbon layers or bundle of ribbon layers of ferromagnetic material, such as amorphous metal or silicon iron, are continuously wound into loops, whereas the shape of the core loops is effected by means of an appropriate mandrel to be directly formed into its final shape;
    b) the single or multiple ribbon layers of the loops are being cut in that
    - a mechanical device or a laser is used for cutting, allowing fast and precise cutting of the ribbons, and in that
    - all ribbons of the loops are cut at at least one position along the circumference of each ribbon layer.

    Furthermore the invention relates to a method of manufacture of a transformer having a core manufactured according to the method being illustrated before as well as to a transformer provided with such a core manufactured according to the claimed method.
