Abstract
Abstract Methods of radially transposing radially adjacent electrically conductive sheet materials in an electrical winding, which include forming notches in opposite edges of the conductors to be transposed and directing each conductor through the notch in the other. The notches are formed, while increasing the crosssectional area of the conductor adjacent the notch, by folding back a section of conductor to form a notch, and electrically joining certain of the edges of the folded section to the surface of the adjacent sheet material. The transposition is performed by directing each sheet through the notch in the other, and changing the relative positions of the supply roll of sheet material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
295 words
A method of transposing superposed electrically conductivesheet materials, comprising the steps of: cutting a first sheet material, having first and second edges, from the first edge thereof, at first and second spaced points, to form first and second cuts having predetermined angles relative to the first edge, the first and second cuts proceeding at least to the midpoint of the sheet width, folding the section of sheet material disposed between the first and second cuts against the portion of the sheet material located between the ends of the first and second cuts and the second edge of the sheet material, to form a notch in the first edge of the first sheet material, electrically joining the edges of the folded section to the portion of the sheet material it is folded against, cutting a second sheet material having first and second edges, from the second edge thereof, at first and second spaced points to form first and second cuts having predetermined angles relative to the second edge, with the first and second cuts proceeding at least to the midpoint of the sheet width, folding the section of sheet material disposed between the first and second cuts against the portion of the sheet material located between the ends of the first and second cuts and the first edge of the sheet material, to form a notch in the second edge of the second sheet material, electrically joining the edges of the folded section to the portion of the sheet material it is folded against, and transposing the relative positions of the superposed first and second sheet materials by directing the first sheet material through the notch in the second sheet material, and by directing the second sheet material through the notch in the first sheet material.
Claim 2
Independent Claim
295 words
A method of transposing superposed electrically conductivesheet materials, comprising the steps of: cutting a first sheet material, having first and second edges, from the first edge thereof, at first and second spaced points, to form first and second cuts having predetermined angles relative to the first edge, the first and second cuts proceeding at least to the midpoint of the sheet width, folding the section of sheet material disposed between the first and second cuts against the portion of the sheet material located between the ends of the first and second cuts and the second edge of the sheet material, to form a notch in the first edge of the first sheet material, electrically joining the edges of the folded section to the portion of the sheet material it is folded against, cutting a second sheet material having first and second edges, from the second edge thereof, at first and second spaced points to form first and second cuts having predetermined angles relative to the second edge, with the first and second cuts proceeding at least to the midpoint of the sheet width, folding the section of sheet material disposed between the first and second cuts against the portion of the sheet material located between the ends of the first and second cuts and the first edge of the sheet material, to form a notch in the second edge of the second sheet material, electrically joining the edges of the folded section to the portion of the sheet material it is folded against, and transposing the relative positions of the superposed first and second sheet materials by directing the first sheet material through the notch in the second sheet material, and by directing the second sheet material through the notch in the first sheet material.
Claim 3
Dependent Claim
111 words
The method of claim 1 including the step of providing a sheet of electrical insulating material having first and second edges, cutting the sheet of electrical insulating material to provide first and second cuts which extend inwardly from the first and second edges thereof, respectively, for a predetermined dimension, disposing the sheet of electrical insulating material between the first and second sheets of electrically conductive material, with the first sheet of electrical conductive material proceeding through the second cut in the sheet of insulating material, and the second sheet of electrical conductive material proceeding through the first cut, at the point of transposing the first and second electrically conductive sheet materials.
Claim 4
Dependent Claim
114 words
The method of claim 1 including the step of providing first and second sheets of electrical insulating material each having first and second edges, cutting each of the first and second sheets of electrical insulating materials inwardly from one edge thereof, and interleaving the first and second sheets of electrical insulating material with the transposed first and second sheets of electrically conductive material, with the first electrically conductive sheet material and the first sheet of insulating material proceeding through the cut in the second sheet of insulating material, and with the second electrically conductive sheet material and the second sheet of insulating material proceeding through the cut in the first sheet of insulating material.
