Abstract
Abstract A method and apparatus for the continuous application of strip-, ribbon- or patch-shaped coatings of a noble metal to an electrically conductive tape by utilizing non-conductive belt means moving in concert with the tape as they simultaneously traverse an electrolitic solution. The non-conductive belt means shields the tape from the solution in those areas where a coating is not desired.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
176 words
An apparatus for continuously electroplating a longitudinally moving elongated strip with a conductive surface, comprising: a frame; a wheel mounted on said frame for rotation about a horizontal axis and having a circumferential face; guide means for guiding said moving strip into engagement with said face over a predetermined portion thereof and in the direction of rotation of said wheel; a masking strip continuously guided over said elongated strip for selectively masking areas on said elongated strip which are not to be electroplated; a tank; said tank adapted to contain an electrolyte at a predetermined level, said tank being positioned relative to said wheel and framework whereby the lower portion of said wheel is immersed in said electrolyte; a tubular member in said tank opposite the circumferential face of said wheel with respect to the portion of said wheel immersed in said electrolyte; spray openings in said tubular member and directed toward said face; means for supplying electrolyte under pressure to said tubular member; and an anode arranged in said tank independently of said tubular member.
Claim 2
Independent Claim
176 words
An apparatus for continuously electroplating a longitudinally moving elongated strip with a conductive surface, comprising: a frame; a wheel mounted on said frame for rotation about a horizontal axis and having a circumferential face; guide means for guiding said moving strip into engagement with said face over a predetermined portion thereof and in the direction of rotation of said wheel; a masking strip continuously guided over said elongated strip for selectively masking areas on said elongated strip which are not to be electroplated; a tank; said tank adapted to contain an electrolyte at a predetermined level, said tank being positioned relative to said wheel and framework whereby the lower portion of said wheel is immersed in said electrolyte; a tubular member in said tank opposite the circumferential face of said wheel with respect to the portion of said wheel immersed in said electrolyte; spray openings in said tubular member and directed toward said face; means for supplying electrolyte under pressure to said tubular member; and an anode arranged in said tank independently of said tubular member.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 and including means for insuring accurate registration of said masking strip with said elongated strip.
Claim 4
Dependent Claim
13 words
The apparatus of claim 1 and including tensioning means for said masking strip.
Claim 5
Dependent Claim
13 words
The apparatus of claim 1 and including means for cleaning said masking strip.
Claim 6
Dependent Claim
17 words
The apparatus of claim 1 wherein the circumferential face of the wheel is of a resiient material.
Claim 7
Dependent Claim
28 words
The apparatus of claim 1 wherein said tubular member is arranged beside the wheel, when seen in a direction perpendicular to the axis of rotation of the wheel.
Claim 8
Dependent Claim
14 words
The apparatus of claim 1 and including a second tubular member in said tank.
Claim 9
Dependent Claim
45 words
The apparatus of claim 7 and including plural masking strips lying against the outer surface of the elongated strip laterally spaced from each other to expose longitudinal areas on said elongated strip, said tubular members being arranged opposite the exposed portions of the elongated strip.
Claim 10
Dependent Claim
23 words
The apparatus of claim 1 wherein a second tubular member is arranged at a distance from the axis of rotation of the wheel.
