ABSTRACT:
A method for the manufacture of a layer winding for transformers, measuring transformers, choke coils or the like is to be so improved that the insulation of such a layer winding exhibits practically no free spaces in the insulating tape edge areas. This is assured in that when reaching the outer end face (12) of a layer winding edge (4), the insulating tape (2) is continued to be wound and the band portion (13) of the insulating tape (2) which projects beyond the edge face (12) is continuously cut off. The remaining residual portion of the insulating tape (15) is then continued to be wound with zero pitch for such length of time until the free spaces which otherwise occur at the layer winding edge (4') are filled out.
