A system of rollers can transfer fluid from a reservoir to an electrically conductive wire feeding past the reservoir. The system can include a first cylinder that contacts the reservoir and rotates to pick up fluid from the reservoir. A second cylinder can contact the first cylinder and rotate. Fluid can transfer between the first cylinder and the second cylinder. The second cylinder can contact the feeding wire such that the second cylinder applies the fluid to the wire as the wire feeds past the second cylinder. Accordingly, two rotating cylinders can cooperatively transfer fluid from the reservoir to the moving wire.

A system for manufacturing wire having a mill and a finishing station configured to receive the wire output from the mill in a continuous fashion. The mill has first and second dies and first and second capstans. The first die is configured to receive a wire having a first cross-sectional area and to reduce the cross-sectional area of the wire as it passes through the first die. The first capstan is configured to receive the wire from the first die and apply a first force on the wire. The second die is configured to receive the wire from the first capstan and to further reduce the cross-sectional area of the wire as it passes through the second die. The second capstan is configured to receive the wire from the second die and apply a second force on the wire. The wire exits the mill having a second cross-sectional area that is smaller than the first cross-sectional area, and is finished by the finishing station.
