Abstract
Abstract An electrolysis device for electrolytic deposition of a metal on at least one surface of the tape which has been precoated with a metal provides an electrolytic metal deposition band in which there is a first electrode for connection to a first voltage source. A tape drive is provided for moving the tape through the bath including first guide rollers defining a single loop for the tape through the bath. A second electrode is provided in the tape path and mounted to contact the tape above the entrance to the bath and over an area of the one metallized surface and is connected to a second source potential. Second guide rollers along the tape path downstream of the bath, including a second guide roller contact the metallized surface and is connected to a third source potential.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
142 words
An electrolysis device for electrolytic deposition of a metal on at least one surface of a tape which has been precoated with a metal on that surface, comprising: an electrolytic metal deposition bath; first electrode means in said bath for connection to a first pole of a source; tape drive means for moving the tape through the bath including first guide rollers defining a single tape loop through the bath; second electrode means in the tape path and mounted immediately above the bath to provide areal wiping contact of the tape over an area of the one metallized surface immediately prior to entrance into said bath and connected to a second pole of the source; and second guide rollers along the tape path downstream of the bath including a second guide roller contacting the metallized surface and connected to a respective source.
Claim 2
Dependent Claim
142 words
An electrolysis device for electrolytic deposition of a metal on at least one surface of a tape which has been precoated with a metal on that surface, comprising: an electrolytic metal deposition bath; first electrode means in said bath for connection to a first pole of a source; tape drive means for moving the tape through the bath including first guide rollers defining a single tape loop through the bath; second electrode means in the tape path and mounted immediately above the bath to provide areal wiping contact of the tape over an area of the one metallized surface immediately prior to entrance into said bath and connected to a second pole of the source; and second guide rollers along the tape path downstream of the bath including a second guide roller contacting the metallized surface and connected to a respective source.
Claim 3
Dependent Claim
62 words
The electrolysis device of claim 1, wherein both sides of the tape are precoated with metal, and wherein: said second electrode means comprises first and second electrodes including respective rods each including an arcuate-shaped surface and positioned with respect to one another to provide an S-shaped portion of the tape path for areal wiping contact with both metallized surface of the tape.
Claim 4
Dependent Claim
23 words
The electrolysis device of claim 1, and further comprising: cooling means mounted for and operative to cool the tape after leaving said bath.
Claim 5
Dependent Claim
24 words
The electrolysis device of claim 1, and further comprising: cooling means mounted for and operative to cool the tape at said second electrode means.
Claim 6
Dependent Claim
38 words
The electrolysis device of claim 4, wherein: said cooling means comprises chamber means defining at least one chamber including first and second electrodes therein and ports communicating with said chamber for supporting a flow of a coolant therethrough.
