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...
In an apparatus for producing filaments from a rod of high melting point material wherein said apparatus includes means for liquefying said rod to provide a pendant drop at one end thereof and a rotating heat extracting member for engaging said pendant drop, the improvement wherein said means for liquefying said rod comprises: first heating means for heating both said end of said rod and a region adjoining said end by thermal radiation to a first temperature immediately below the melting point of said material, said first heating means substantially non-...
