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 whilst metal is being electrolytically deposited on the fibres.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
63 words
A device for depositing electrolytically a metal on conductive fibers forming a skeleton, said device comprising an electrolytic cell for lodging the electrolytic bath and said conductive fibers, a carding apparatus situated in said electrolytic cell and comprising at least two sets of teeth, and means for continuously imparting to said two sets of teeth a relative movement with respect to each other.
Claim 2
Independent Claim
63 words
A device for depositing electrolytically a metal on conductive fibers forming a skeleton, said device comprising an electrolytic cell for lodging the electrolytic bath and said conductive fibers, a carding apparatus situated in said electrolytic cell and comprising at least two sets of teeth, and means for continuously imparting to said two sets of teeth a relative movement with respect to each other.
Claim 3
Dependent Claim
15 words
A device according to claim 1, in which the electrolytic cell comprises a rotatable drum.
Claim 4
Independent Claim
161 words
A device for preparing fibrous metal material wherein metal is electrolytically deposited on conductive fibers forming a skeleton, the device comprising a rotatable drum containing a fiber-carding device which fiber-carding device operates during rotation of the drum to card fibers situated within the drum whilst metal is being electrolytically deposited on the fibers, the axis of rotation of the drum being about 20° to about 40° with respect to the vertical and in which the fiber-carding device comprises a stationary comb secured to a holder of the drum the comb having teeth disposed substantially parallel to the axis of rotation of the drum, the free ends of the teeth being near an end of the drum and also comprises finger-like projections disposed in circles and secured to the said end of the drum and being substantially parallel to the axis of rotation of the drum such that the projections move between the teeth of the comb during rotation of the drum.
Claim 5
Independent Claim
161 words
