Appl. No.:

5/550348

Inventors:

Curtis N. Lovejoy - Walpole MA
Leo N. Kosowsky - Sharon MA
Paul C. Holte - Canton MA

Assignee:

National Plastics & Plating Supply - Terryville CT

International Classification:

C25D 502
C25D 1700

US Classification:

204202

Abstract:

Apparatus for selective electroplating of discreet areas of strips intermittently advanced through said apparatus. A particularly important aspect of the apparatus is the means whereby the strip is advanced intermittently but is, at all times, held under tension by a dual-clutch arrangement comprising two indexing wheels, a drag clutch positioned to control tension on a first wheel at one side of the electroplating bath, and another indexing wheel intermittently operated to advance the strip on intermittent engagement by controlled by a second clutch mechanism.

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.
