Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A method of producing a flexible electric line having at least one insulated conductor, by which method at least one metallic covering comprising a plurality of metallic individual elements is applied as a winding and an insulation of the conductor; the method comprising the steps of: winding a metal tape, as covering, around the insulation of the conductor; and separating the tape into individual elements by cuts extending parallel to the direction of the tape directly before an engagement of the tape with the insulation during said step of winding.
Claim 2
Independent Claim
90 words
A method of producing a flexible electric line having at least one insulated conductor, by which method at least one metallic covering comprising a plurality of metallic individual elements is applied as a winding and an insulation of the conductor; the method comprising the steps of: winding a metal tape, as covering, around the insulation of the conductor; and separating the tape into individual elements by cuts extending parallel to the direction of the tape directly before an engagement of the tape with the insulation during said step of winding.
Claim 3
Dependent Claim
18 words
A method according to claim 1, comprising a step of tensioning the metal tape during said winding step.
Claim 4
Dependent Claim
42 words
A method according to claim 1 wherein said step of separating provides that the individual elements have approximately the same length from beginnings of the cuts up to the points of engagement of the individual elements with a winding encircling the insulation.
Claim 5
Dependent Claim
21 words
A method according to claim 1, wherein said step of separating includes a cutting of the tape by rotatably mounted knives.
Claim 6
Dependent Claim
15 words
A method according to claim 4, wherein said cutting is accomplished by driving the knives.
Claim 7
Dependent Claim
46 words
A method according to claim 1 wherein said step of winding includes a winding of two metal tapes as covering of the insulation; and said step of separating includes separating the two tapes into individual elements which are applied as windings with opposite direction of lay.
Claim 8
Dependent Claim
42 words
A method according to claim 6, wherein the width of the individual elements of one of said tapes in a winding of one lay differs from the width of the individual elements of the tape in the winding of the other lay.
Claim 9
Dependent Claim
23 words
A method according to claim 1, further comprising a step of forming a jacket upon the metal covering concurrently with said winding step.
