Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
148 words
Apparatus for electroplating a metallic deposit on interconnected or bandoliered elongate metallic and/or metallized products, said apparatus comprising: (a) first means for guiding and displacing the elongate products along a first predetermined path; (b) a plurality of masking devices each one of which comprises a solid, non-flexible pin surrounded by a material in the shape of a tube, said plurality of masking devices being attached in a regular pattern to an endless member; (c) second means for guiding and displacing said endless member along a second predetermined path a part of which coincides that a part of said first predetermined path so that each one of the elongate products is received between and contacts two adjacent ones of said plurality of masking devices; and (d) third means for supplying electrolyte to the elongate products while the elongate products are moving along said part of said first predetermined path.
Claim 2
Dependent Claim
148 words
Apparatus for electroplating a metallic deposit on interconnected or bandoliered elongate metallic and/or metallized products, said apparatus comprising: (a) first means for guiding and displacing the elongate products along a first predetermined path; (b) a plurality of masking devices each one of which comprises a solid, non-flexible pin surrounded by a material in the shape of a tube, said plurality of masking devices being attached in a regular pattern to an endless member; (c) second means for guiding and displacing said endless member along a second predetermined path a part of which coincides that a part of said first predetermined path so that each one of the elongate products is received between and contacts two adjacent ones of said plurality of masking devices; and (d) third means for supplying electrolyte to the elongate products while the elongate products are moving along said part of said first predetermined path.
Claim 3
Dependent Claim
66 words
Apparatus as recited in claim 1 wherein: (a) said first means comprising a main guide wheel that is rotatable about a first axis and a plurality of auxiliary guide wheels that provide guidance for the elongate products along at least a part of the circumference of said main guide wheel and (b) said second means comprise a carrier wheel that is rotatable about said first axis.
Claim 4
Dependent Claim
38 words
Apparatus as recited in claim 1 wherein at least one masking belt made of non-conductive material cooperates with said main guide wheel to prevent metal deposition on those areas of the elongate products where no deposit is desired.
Claim 5
Dependent Claim
54 words
Apparatus as recited in claim 1 wherein: (a) a space is provided between said main guide wheel and said carrier wheel; (b) said space is in communication with said third means; and (c) said third means comprises a slot-shaped exit for jetting electrolyte outwardly towards the elongate product and said plurality of masking devices.
Claim 6
Dependent Claim
15 words
Apparatus as recited in claim 4 wherein said third means further comprises a stationary anode.
Claim 7
Dependent Claim
17 words
Apparatus as recited in claim 5 wherein said stationary anode is a part of said slot-shaped exit.
Claim 8
Dependent Claim
42 words
Apparatus as recited in claim 2 wherein said third means comprises a reservoir placed outside said main guide wheel and a slot-shaped exit concentric to said first axis for jetting electrolyte inwardly towards the elongate products and said plurality of masking devices.
Claim 9
Dependent Claim
15 words
Apparatus as recited in claim 7 wherein said third means further comprises a stationary anode.
Claim 10
Dependent Claim
17 words
Apparatus as recited in claim 8 wherein said stationary anode is a part of said slot-shaped exit.
Claim 11
Dependent Claim
56 words
Apparatus as recited in claim 1 wherein, in the positions where no elongate products are received between adjacent ones of said plurality of masking devices, there is some space between the inner wall of the flexible, resilient material and the outer wall of the solid, non-flexible pin in the direction of movement of the elongated products.
Claim 12
Dependent Claim
57 words
Apparatus as recited in claim 1 wherein: (a) said first means comprise two cooperating masking belts made of non-conductive material between which, during operation, the area of the elongate products requiring no metal deposition are clamped and (b) said second means comprises another belt that carries said plurality of masking devices between said two cooperating masking belts.
