Abstract: A high speed aluminum wire anodizing machine and process are provided which includes anodizing aluminum wire in an anodizer tank having wire ingress and egress openings. At least two adjacent rotatable wire accumulator drums are provided in the tank, preferably with means for producing a flow of anodizing electrolytes into each of the drums through an end hub thereof and out of the sidewalls of the drums passed circumferential wire separators. An anode is located proximal to the wire ingress opening, preferably in a contact cell which has an adjustable wire egress window. At least one cathode is provided in the tank. The cathode is preferably either between the drums or a pair of cathodes are provided above and below the drums adjacent to the sidwalls thereof, or both.
