    • The present invention relates to an electrospinning apparatus comprising a spinning tube having a plurality of spouting holes, in which the spinning tube which is rotatable and having a plurality of spouting holes instead of conventional nozzles is employed as means for electrospinning a spinning solution in the direction of a collector. According to the present invention, electrospinning is performed using both electrostatic force and centrifugal force, thereby increasing discharge amount of unit polygonal tube per unit time and thus significantly improving productivity. Compared to conventional electrospinning apparatuses that use nozzles, the necessity of replacing and cleaning nozzles is eliminated and production processes are thus simplified. As the collector is located above the spinning tube having the plurality of spouting holes, a phenomenon (drop phenomenon) in which the spinning solution in a solution state not a fibrous state drops onto the collector during electrospinning is prevented to improve the quality of the nanofiber web being produced.

    • Die Erfindung betrifft eine Vorrichtung zum Schmelzspinnen einer Vielzahl von strangförmigen Filamenten. Hierzu ist zumindest eine Spinndüse an einem Düsenträger gehalten. Die Spinndüse weist ein Gehäuse mit einem Schmelzeeinlaß sowie eine Düsenplatte mit einer Vielzahl von Düsenbohrungen auf. Dabei ist die Spinndüse zur Führung einer druckbelasteten Schmelze mit dem Gehäuse an einem Schmelzezulauf des Düsenträgers dichtend gespannt. Um bei Betrieb ein Selbstabdichten zwischen dem Düsenträger und der Spinndüse zu erreichen, ist erfindungsgemäß die Wandung des Gehäuses der Spinndüse derart elastisch ausgebildet, daß unter Wirkung des Schmelzedruckes eine Verformung des Gehäuses eintritt und daß die Verformung des Gehäuses eine Druckkraft zur selbstdichtenden Verspannung erzeugt.
