Abstract

Abstract Metallic copper or other metal, such as nickel, to be subjected to electrolytic refining is formed into a continuous slab strip of anode width and thickness. The strip is cut transversely of its width to form successive, rectangularly shaped, anode slab blanks, each having a pair of elongate members extending longitudinally of the strip at one set of corners of the blank. The so-formed blanks are passed individually through a bending operation, by which the elongate members of each blank are bent outwardly laterally of the blank and preferably within the plane thereof and intermediate the lengths of such members to form suspension lugs wholly integral with the remainder, i.e. slab body, of the blank, while being held preferably at the notched other set of corners of the blank from which the elongate members of the immediately preceeding blank were cut. The individual anodes, as articles of manufacture, have respective slab bodies, with wholly integral and upwardly and laterally outwardly projecting lugs at the upper corners thereof to serve as suspension hangers. These anodes are characterized by elongate notches at the lower corners of the respective slab bodies, such notches extending upwardly along the lateral margins of the slab bodies.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 64 words
A method in accordance with claim 1, wherein the slab strip is continuously ejected from a casting machine, and the successively cut slab segments are separated from the continuous slab strip as it travels by conveying each slab segment, in turn, away from the slab strip in the direction of slab strip travel, but at a speed faster than the slab strip is traveling.
Claim 2
Dependent Claim 18 words
A method in accordance with claim 1, wherein the elongate lugs or ears are bent intermediate their lengths.
Claim 3
Dependent Claim 85 words
A method in accordance with claim 3, wherein the elongate members are bent over respective anvil blocks by means of reciprocating rollers. 5. A method in accordance with claim 4, wherein the individual anode blanks are held during the bending operation by rigid blocks inserted in the pair of elongate notches that are left at the opposite set of corners of the slab body by the cutting of the elongate lugs or ears from the strip, said blocks being held stationary during the bending operation.
