Abstract
Abstract Apparatus for electroplating selected areas on consecutive segments of metal strip, the apparatus comprising means to advance the strip, means for isolating inertial movement of the strip to hold the strip in a fixed position at all times advancement is not required, and an electroplating cell formed of two parts adapted to clamp together hydraulically isolating all but the aforesaid selected areas from contact with the electroplating fluid. In one embodiment of the invention there is an electronic means to sense whether the proper advancement of the strip has been achieved.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
92 words
In apparatus for electroplating pre-selected portion of a continuous metallic strip and comprising A. advancement means adapted to engage said strip and move it forward intermittently; B. an electroplating cell adapted to clamp and seal portions of the surface of said strip to hydraulically seal portions of said strip against exposure to electroplating fluid and to hydraulically seal a plurality of other pre-selected portions of the surface to be electroplated into a conduit forming means to supply electroplating fluid to said plurality of surfaces; and C. means to wind up said strip.
Claim 2
Dependent Claim
