ABSTRACT:
There is described an improved apparatus for producing filaments from a high melting point material by forming a pendant drop at the end of the material and engaging the drop with a rotating heat extracting member (e.g. copper disc). The improvement to the apparatus comprises a pair of heating components to heat the material to a temperature immediately below its melting point and thereafter heat only the end of the material to the melting point. The result is a vibration free pendant drop suspended from the rod's end. A method for making the filament is also described.
