ABSTRACT OF THE DISCLOSURE A method of, and means for, controlling the manufacture of a winding for an inductive apparatus, for example a trans- former winding or a reactor winding, which winding is of the kind comprising a plurality of turns of a sheet composed of an electrically conductive metallic foil and an electrically insulating film on each side of the metallic foil. During the winding of the sheet, the metallic foil together with the insulating films is passed through at least one electrode device which comprises at least two rolls arranged one on each side of the sheet and having a different voltage compared with the metallic foil. At the electrode device, the insulating films are pressed with a certain pressure against the metallic foil across the entire width of the latter by means of the rolls, and the electrical insulation of both sides of the sheet is checked by separately sensing the leakage current which via each of the rolls passes through the respective insulating film.
