Abstract
The apparatus is provided with a wire guiding means disposed in a liquid bath for turning the direction of a wire to feed the wire into and out of the bath contained by the liquid. The wire guiding means includes a tubular conduit having a first open end disposed in the liquid, a second open end disposed above the liquid, and a middle curved portion for guiding the wire through the tubular conduit. The tubular conduit can be at least partially filled with the liquid. Preferably, the treatment liquid is an electrodeposition liquid. A plurality of the tubular conduits may be disposed in the bath substantially parallel with each other. Preferably the first open end is connected to a bottom portion of the bath through a coupling such that the treatment liquid in the bath can flows into the tubular conduit. The second open end is positioned higher than the first open end. Preferably, the apparatus further includes a main supporting shaft and a secondary supporting shaft positioned opposed to the main supporting shaft. The main supporting shaft has a channel defined on an outer peripheral surface thereof for receiving and contacting an inner curvature surface of the curved portion of the…
