ABSTRACT:
An apparatus and method for forming round wire from non-round wire has: a heat extracting drum having a semi-circular channel formed in and entirely around its outer circumferential surface; a feed device for directing a precursor wire into the channel; and a heater for melting the precursor wire in the channel. The wire is typically flat and is stood up on edge, perpendicular to the surface of the drum, melted with the heater, solidified and removed. The surface tension and wetting characteristics of the liquid metal cause it to "bead up", forming a near round wire when solidified.
