Abstract
An apparatus and method for continuously manufacturing metal filaments in mass production. In accordance with the present invention, molten metal is hung in a state freely depending from the tip of a metal bar by its surface tension without using any vessel. The metal filament manufacturing apparatus includes an induction coil upwardly bent in the form of a nose shape at regions thereof where metal filaments are discharged while being soared up, respectively, so as to prevent the molten metal of each of the metal bars from being affected by the induction coil during soaring of the metal filaments. The apparatus also includes wiping assembly for removing residual metal materials left on a spinning disk.
