ABSTRACT:
Fiberization of thermoplastic materials is effected by a technique employing an attenuating blast having a Coanda surface on the blast nozzle lip, the arrangement providing for delivery of a stream of molten material into the region of gaseous currents flowing over the Coanda surface into the blast. Provision is also made for employment of a secondary jet directed to flow over at least a part of the Coanda surface into the blast.
