Abstract
Abstract A corona discharge wire made of electrically conducting wire of high tensile strength to which is connected a metallic fixing element on both sides of the discharge portion. The element forms a fused mass disposed in a zone surrounding the wire and solidified around it. The fixing element may consist of two parallel pieces of wire interconnected by an annular extension.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
109 words
A method of producing a corona discharge wire comprising disposing an electrically conductive wire of high tensile strength between two spaced mounting elements, each mounting element being bent to have two portions in spaced parallel relation surround said corona discharge wire which is passing through the middle of a securing hole provided in each mounting element, pre-stressing said discharge wire across clamping and tensioning points outside and beyond the mounting elements, said clamping and tensioning points being aligned with the mounting elements, and spot-welding said mounting elements to said discharge wire to form a solidified fused mass to include and to fix said discharge wire to the mounting elements.
Claim 2
Independent Claim
109 words
A method of producing a corona discharge wire comprising disposing an electrically conductive wire of high tensile strength between two spaced mounting elements, each mounting element being bent to have two portions in spaced parallel relation surround said corona discharge wire which is passing through the middle of a securing hole provided in each mounting element, pre-stressing said discharge wire across clamping and tensioning points outside and beyond the mounting elements, said clamping and tensioning points being aligned with the mounting elements, and spot-welding said mounting elements to said discharge wire to form a solidified fused mass to include and to fix said discharge wire to the mounting elements.
Claim 3
Dependent Claim
41 words
The method as claimed in claim 1, wherein said pre-stressing is applied to said corona discharge wire in the direction in which said two portions of said mounting elements extend during the fusing of said discharge wire with each mounting element.
