Abstract: A transformer winding is formed of a tape-like conductor running helically in a plurality of layers in which the tape advances successively from one end of the layer to the other in overlapping relationship with the overlap increasing from layer to layer so that the length of the layers becomes progressively shorter towards the outside. Insulation between the successive helical coils is wound on at the same time that the layers are formed.

Abstract: AN INSULATING TAPE WITH SPACERS FOR FORMING AXIAL CHANNELS IN WINDINGS OF COILS FOR TRANSFORMERS IS FORMED BY APPLYING AT SPACED INTERVALS ALONG A SIDE OF A CONTINUOUS BASE INSULATING TAPE COATED WITH AN ADHESIVE ROLLS OF AN INSULATING TAPE LIKEWISE COATED ON ONE SIDE WITH AN ADHESIVE AND APPLYING HEAT AND PRESSURE. EACH ROLL HAS A PROJECTING PORTION ALSO ADHESIVELY SECURED TO THE MAIN TAPE.
