Abstract
Abstract In a procedure of preparing fibrous metal material by electrolytically deiting metal on conductive fibres forming a skeleton, the fibres are carded during deposition of the metal. The fibres are carded in a rotatable drum containing a fibre carding device which operates during rotation of the drum to card fibres while metal is being electrolytically deposited on the fibres.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
57 words
In a process for preparing fibrous metal material wherein the metal is electrolytically deposited on conductive fibres forming a skeleton, the improvement comprising continuously carding the fibres during deposition of the metal thereof, said carding comprising subjecting said fibres to the action of at least two sets of teeth in relative movement with respect to each other.
Claim 2
Dependent Claim
57 words
In a process for preparing fibrous metal material wherein the metal is electrolytically deposited on conductive fibres forming a skeleton, the improvement comprising continuously carding the fibres during deposition of the metal thereof, said carding comprising subjecting said fibres to the action of at least two sets of teeth in relative movement with respect to each other.
Claim 3
Dependent Claim
21 words
The process of claim 1, in which the fibres of the skeleton are carbon fibres, the metal being deposited being nickel.
Claim 4
Dependent Claim
21 words
The process of claim 1, in which the fibres of the skeleton are carbon fibres, the metal being deposited being lead.
Claim 5
Dependent Claim
30 words
The process of claim 1, in which the fibres are situate in a rotating drum and a fibre-carding device in the drum operates during rotation thereof to card the fibres.
Claim 6
Dependent Claim
24 words
Carbon-core metal fibres which comprises metal electrolytically deposited on conductive fibres forming a skeleton, the fibres having been carded during deposition of the metal.
Claim 7
Dependent Claim
24 words
Carbon-core metal fibres which comprises metal electrolytically deposited on conductive fibres forming a skeleton, the fibres having been carded during deposition of the metal.
Claim 8
Dependent Claim
28 words
