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: 18
Claim 1
Independent Claim
143 words
An apparatus for electrolytic treating elongated materials such as hoop materials, rods and wires comprising: a casing having an opening for feeding the material to be treated; a treatment unit consisting of first and second unit halves one upon the other and enclosed in said casing; said unit halves including a through passage for feeding said material to be treated; at least one insulating passage for flowing a treating liquid onto surfaces of said material to be treated as it is transferred through said through passage; said insulating passage being made as a plurality of passages substantially perpendicular to said through passage and extending transversely across said material; electrodes for causing electric current to flow between the electrodes and said material; and at least one insulating shield between said insulating passages and said material for shielding portions of said material from being treated.
Claim 2
Independent Claim
143 words
An apparatus for electrolytic treating elongated materials such as hoop materials, rods and wires comprising: a casing having an opening for feeding the material to be treated; a treatment unit consisting of first and second unit halves one upon the other and enclosed in said casing; said unit halves including a through passage for feeding said material to be treated; at least one insulating passage for flowing a treating liquid onto surfaces of said material to be treated as it is transferred through said through passage; said insulating passage being made as a plurality of passages substantially perpendicular to said through passage and extending transversely across said material; electrodes for causing electric current to flow between the electrodes and said material; and at least one insulating shield between said insulating passages and said material for shielding portions of said material from being treated.
Claim 3
Dependent Claim
44 words
An apparatus as set forth in claim 1, wherein said insulating passages and said electrodes are disposed on both sides of said material, said electrodes being parallel to said insulating passages and substantially perpendicular to said through passage and extending transversely across said material.
Claim 4
Dependent Claim
50 words
An apparatus as set forth in claim 1, wherein said material is a sheet of material, and said insulating passages are disposed on both sides of said sheet with said electrodes disposed in the bottoms of said insulating passages, and said insulating passages including insulating partitions between each insulating passage.
Claim 5
Dependent Claim
52 words
An apparatus as set forth in claim 1, wherein one ends of said passages of the unit halves for the liquid are communicated with each other over a certain length and the shields are cut away to an extent facing said communicated portions of said passages, within which are settled said electrodes.
Claim 6
Dependent Claim
22 words
An apparatus as set forth in claim 4, wherein said communicated portions of said passages are arranged at more than one location.
Claim 7
Dependent Claim
31 words
An apparatus as set forth in claim 1, wherein said shields are formed with at least one through apertures corresponding in configuration to a portion on the material to be treated.
Claim 8
Dependent Claim
19 words
An apparatus as set forth in claim 1, wherein said electrodes extend all over the passage for the liquid.
Claim 9
Dependent Claim
37 words
An apparatus as set forth in claim 1, wherein one of said unit halves is provided only with flat cut portion but devoid of the other portions, such as said electrodes and said passages for the liquid.
Claim 10
Dependent Claim
29 words
An apparatus as set forth in claim 1, wherein said passages for the liquid are varied in shape and width corresponding to portions on the material to be treated.
Claim 11
Dependent Claim
26 words
An apparatus as set forth in claim 1, wherein said insulating shield is formed in endless and is driven contact and in synchronism with said material.
Claim 12
Dependent Claim
20 words
An appartus as set forth in claim 10, wherein said endless shield is arranged on each side of the material.
Claim 13
Dependent Claim
60 words
An apparatus as set forth in claim 1, wherein said through passage for the material is formed in a shape corresponding to a section of a material to be treated such as rods and wires having a section such as circular, polygonal and the like, and said electrodes and shields are formed in configuration corresponding to that of the passage.
Claim 14
Dependent Claim
25 words
An apparatus as set forth in claim 1, the treatment unit is so constructed that a plurality of materials are fed to be treated simultaneously.
Claim 15
Dependent Claim
27 words
An apparatus as set forth in claim 13, a plurality of the treatment units are piled up, thereby enabling a plurality of materials to be treated simultaneously.
Claim 16
Dependent Claim
29 words
An apparatus as set forth in claim 13, wherein said treatment unit is provided with a plurality of through passages for feeding said plurality materials to be treated simultaneously.
Claim 17
Dependent Claim
23 words
An apparatus as set forth in claim 1, wherein there are provided with a plurality of supply pipes for supplying the treating liquid.
Claim 18
Dependent Claim
20 words
An apparatus as set forth in claim 16, wherein said supply pipes are provided over and under said treatment unit.
