Abstract
A process and apparatus for the manufacture of fibers from fusible materials and particularly materials of low viscosity. The melt and gaseous flow medium is passed through a Laval-nozzle at a supersonic speed. The nozzle and speed are so selected as to cause an abrupt temperature drop in the flow medium within the nozzle which causes the melt to solidify into fibers.
