Abstract

The polymer granular melt (1) is whirled out of a rotating nozzle head (6) through a plurality of exit holes (24) with fibre formation (32) and the fibres formed (9) are deposited on a collecting surface (12) in web form (15). This polymer melt is introduced into the nozzle head (6) under a preliminary pressure of 1 bar to 200 bar, preferably 1 bar to 50 bar. Furthermore, the fibres (32) are deflected by a high-speed gas stream (7, 8) in a radial direction at a radial distance of 10 mm to 200 mm from the exit holes (24) and, in the course of being deflected, are simultaneously drawn and stretched. The melt streams (32) exiting from the exit holes (24) can be additionally drawn by gas streams (26, 34) exiting in the vicinity of the exit holes (24) at the nozzle head (6) with a predominantly radial component before coming under the influence of the axial deflecting gas stream (7, 8).
