Abstract

An apparatus for producing filaments from meltable material utilizing centrifugal force includes a hollow body (2) rotating at high speed, whose bottom (5) the meltable material strikes from above in the solid state. The wall of the hollow body, shaped as a cylindrical casing, is formed by a heating device (4) which includes metal elements running in a rectangular and helical fashion, such that the interstices of the helix form the discharge openings for the molten material.
