Abstract

Abstract A method of electrolytic treating elongated materials such as hoop materials, rods and wires and an apparatus for carrying out the method comprising a treating unit consisting of unit halves comprising a through passage for feeding the material to be treated, insulating passages for flowing a treating liquid onto the surfaces of the material to be treated, electrodes for flowing electric current between the material and the electrodes and an insulating shield for shielding portions of the material not to be treated. When the material is fed continuously or intermittently through the treating unit while electric current flows between the electrodes and the material, the material is subjected to the electrolytic treatment or plating, of which plated portions are of desired size, shape and location on the material.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 109 words
A method of electrolytic treating elongated materials such as hoop materials, rods and wires comprising: providing at least one insulating shield for shielding portions not to be treated of at least one material simultaneously to be treated, supplying a treating liquid to be confined in at least one flow path with a supplying direction transversely of a direction of feeding said material and substantially in a plane including said material whereby said treating liquid flows transversely past substantially an entire surface of said material, causing electric current to flow through said confined liquid in said flow path to said unshielded material, and feeding said material past said flow path.
Claim 2
Independent Claim 109 words
A method of electrolytic treating elongated materials such as hoop materials, rods and wires comprising: providing at least one insulating shield for shielding portions not to be treated of at least one material simultaneously to be treated, supplying a treating liquid to be confined in at least one flow path with a supplying direction transversely of a direction of feeding said material and substantially in a plane including said material whereby said treating liquid flows transversely past substantially an entire surface of said material, causing electric current to flow through said confined liquid in said flow path to said unshielded material, and feeding said material past said flow path.
Claim 3
Dependent Claim 23 words
A method as set forth in claim 1, wherein said treating liquid is confined to flow only across one surface of said material.
Claim 4
Dependent Claim 33 words
A method as set forth in claim 1, wherein a plurality of materials arranged one above another are simultaneously treated by separately confining said treating liquid in separate flow paths across each material.
Claim 5
Dependent Claim 35 words
A method as set forth in claim 1, wherein a plurality of materials arranged side by side are simultaneously treated by confining said treating liquid to flow in a single flow path across each material.
Claim 6
Dependent Claim 14 words
A method as set forth in claim 1, wherein said material is fed intermittently.
Claim 7
Dependent Claim 14 words
A method as set forth in claim 1, wherein said material is fed continuously.
Claim 8
Dependent Claim 26 words
A method as set forth in claim 1, wherein said insulating shield is formed endless and is moved in contact and in synchronism with said material.
