Beschreibung
Zusammenfassung:	The present disclosure relates to a method and a device for application of liquid polymeric material onto the active spinning zone of the cord of the spinning member of the spinning electrode, where the application means moving reversibly along the active spinning zone of the cord in the device for production of nanofibres through electrostatic spinning of liquid material in electrostatic field of high intensity between at least one spinning electrode and against it arranged collecting electrode. The liquid polymeric material is applied onto the cord around its whole circumference without any contact with gaseous environment in the spinning space, where the application means reversibly moves, whereas while the cord is leaving the application means the thickness of the layer of the liquid polymeric material is being reduced and immediately after leaving the application means the process of electrostatic spinning of the liquid polymeric material applied on the cord is started.
