Claims
- 1. An apparatus for the production of filament from a melt of normally solid material comprising:
- a. a melting chamber adapted to receive said material, said chamber including means to melt said material and means to control the environment therein;
- b. an extrusion orifice in the bottom of said melting chamber, adapted for extruding a filament of molten material;
- c. an interface chamber below said orifice through which said filament is adapted to pass, said interface chamber including means for providing an evacuated space or controlled gaseous atmosphere therein; and
- d. reservoir disposed below said interface chamber into which filament is adapted to be introduced, said reservoir comprising a liquid quenching medium adapted to move cocurrently with the molten filament introduced therein.
- 2. The apparatus of claim 1 including a vertical standpipe immersed below the surface of the liquid quench medium adapted to receive the liquid quench medium in an essentially vertical direction.
- 3. The apparatus of claim 1 including means adapted to prevent vortex formation positioned continguous to the point in reservoir (d) into which the molten filament is adapted to be introduced.
- 4. The apparatus of claim 2 including means for injecting jets of the quench medium into the upper end of said standpipe to inhibit vortex formation in said quench medium.
- 5. The apparatus of claim 3 including a rotating cylinder positioned continguous to said point into which the molten filament is adapted to be introduced, said cylinder adapted to rotate so as to move the quench medium surface in a direction cocurrent with the movement of the filament.
- 6. The apparatus of claim 1 including a weir in said reservoir adapted for overflow of the liquid quench medium in an essentially vertical direction.
