Claim 14:
15. A method for electrically insulating at least one turn of an electrical coil conductor of a coil of an electric machine, the method comprising:
applying a first, electrically conductive layer of an insulating arrangement onto a second, electrically insulating layer of the insulating arrangement to provide a sheet-like slot insulation;
placing the sheet-like slot insulation in a spatial region between a first tooth and a tooth adjacent to the first tooth of the electric machine such that the first, electrically conductive layer enters into electrical contact with an electrically conductive component of the electric machine; and
winding the electrical coil conductor of the respective coil onto each tooth of the electric machine that is in electrical contact with the sheet-like slot insulation, so that the sheet-like slot insulation is positioned between the first tooth and the electrical coil conductor wound onto this first tooth,
wherein, as viewed in an axial direction of the electric machine, the second, electrically insulating layer is dimensioned in such a way that the second, electrically insulating layer protrudes beyond axial ends of the electrically conductive component, and
wherein the first, electrically conductive layer is dimensioned in such a way that the first, electrically conductive layer does not protrude beyond the axial ends of the electrically conductive component.
