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.

Claim 5
Dependent Claim
22 words
CLAMPING SAID STRIP IN FIXED POSITION BETWEEN THE INTERMITTENT MOVEMENTS THEREOF, SAID CLAMPING BEING BETWEEN SAID WINDING APPARATUS AND SAID ELECTROPLATING CELL,
Claim 6
Dependent Claim
22 words
CLAMPING SAID STRIP IN FIXED POSITION BETWEEN THE INTERMITTENT MOVEMENTS THEREOF, SAID CLAMPING BEING BETWEEN SAID WINDING APPARATUS AND SAID ELECTROPLATING CELL,
Claim 7
Dependent Claim
66 words
A process as defined in claim 1 wherein said strip is a fenestrated strip and further comprising the steps of (1) actuating a displacement sensor to feel for a pre-determined placement of an aperture in said strip and (2) stopping the operation of said apparatus in response to the position of said sensor if the displacement sensed is indicative that it has not entered said aperture.
Claim 8
Dependent Claim
22 words
clamping said strip in fixed position between the intermittent movements thereof, said clamping being between said winding apparatus and said electroplating cell,
Claim 9
Dependent Claim
22 words
clamping said strip in fixed position between the intermittent movements thereof, said clamping being between said winding apparatus and said electroplating cell,
Claim 10
Dependent Claim
28 words
WINDING THE ELECTROPLATED STRIP DURING SAID CLAMPING ACTION, THEREBY MECHANICALLY ISOLATING AND WINDING MOVEMENT FROM THE PORTION OF SAID STRIP ON THE ELECTOPLATING CELL-SIDE OF SAID CLAMPING ACTION.
Claim 11
Dependent Claim
28 words
WINDING THE ELECTROPLATED STRIP DURING SAID CLAMPING ACTION, THEREBY MECHANICALLY ISOLATING AND WINDING MOVEMENT FROM THE PORTION OF SAID STRIP ON THE ELECTOPLATING CELL-SIDE OF SAID CLAMPING ACTION.
Claim 12
Dependent Claim
28 words
winding the electroplated strip during said clamping action, thereby mechanically isolating and winding movement from the portion of said strip on the electroplating cell-side of said clamping action.
Claim 13
Dependent Claim
28 words
winding the electroplated strip during said clamping action, thereby mechanically isolating and winding movement from the portion of said strip on the electroplating cell-side of said clamping action.
