Beschreibung
Zusammenfassung:	An apparatus for spinning fine polymer fibers, comprising: a spinneret having at least one polymer supply inlet connected to at least one spinning nozzle outlet from which an uncharged, electrically conductive, polymer-containing liquid stream issues in a downstream direction; a corona charging system comprising an electrically-charged point-electrode, downstream of an insulated from said spinneret and positioned such that an ion field is created by said point-electrode and is intersected by said polymer-containing liquid stream, and a target-electrode which is said uncharged, electrically-conductive, polymer-containing liquid stream; and a collector positioned downstream of said ion field for collecting said fine polymer fibers.
