The invention relates to device for production of nanofibres through electrostatic spinning of polymer solutions comprising a spinning chamber, in which the reservoir of polymer solution is positioned, into which by a section of its circumference extends the rotating spinning electrode of elongated shape connected to one pole of high voltage source of direct current, to whose opposite pole there is connected the collecting electrode arranged in the spinning chamber against the spinning electrode, while a section of circumference of the spinning electrode extends into a polymer solution in the reservoir while the reservoir of polymer solution is divided into the inlet section, into which leads at least one inlet opening, and into which the spinning electrode extends by a section of its circumference, and the outlet section, which is provided with outlet opening.

L'invention concerne un dispositif permettant de produire des nanofibres par filage électrostatique de solutions polymères, qui comprend une chambre de filage contenant un réservoir de solution polymère dans lequel s'étend une section de la circonférence d'une électrode de filage rotative de forme allongée reliée à un pôle d'une source de courant continu à haute tension, le pôle opposé de ladite source étant relié à une électrode collectrice disposée dans la chambre de filage contre l'électrode de filage. Une section de la circonférence de l'électrode de filage s'étend dans la solution polymère contenue dans le réservoir, ledit réservoir de solution polymère étant divisé en une section d'entrée, sur laquelle donne au moins un orifice d'entrée, et dans laquelle s'étend une section de la circonférence de l'électrode de filage, et en une section de sortie, qui est dotée d'un orifice de sortie.
