Abstract: A method of nanofibers production from a polymer solution uses electrostatic spinning in an electric field created by a potential difference between a charged electrode and a counter electrode. The polymer solution for spinning is supplied into the electric field using the surface of a rotating charged electrode. On a part of the circumference of the charged electrode near to the counter electrode, a spinning surface is created for attaining a high spinning capacity. In a device for carrying out the method, the charged electrode is pivoted and part of its circumference is immersed in the polymer solution. The free part of the circumference of the charged electrode is positioned opposite the counter electrode.

Abstract: The invention relates to a method of nanofibres production from a polymer solution using electrostatic spinning in an electric field created by a potential difference between a charged electrode and a counter electrode. The polymer solution (2) is for spinning supplied into the electric field using the surface of the rotating charged electrode (30), while on a part of the circumference of the charged electrode (30) near to the counter electrode (40) is a spinning surface created, by which is a high spinning capacity reached. Further the invention relates to a device for carrying out the method, where the charged electrode (30) is pivoted and by its (bottom) part of its circumference it is immersed in the polymer solution (2), while against the free part of the circumference of the charged electrode (30) is positioned the counter electrode (40).

Abstract: A device for perpendicular stratification of planary fibrous shapes, above all of fibrous web, comprising two synchronously moving elements, connected with the driving mechanism according to the invention consists in that the reciprocating moving elements are connected with their driving mechanism indirectly by the intermediary of at least one robust shaft rigidly fitted in bearings in a rigid framework of the machine, while one element is connected with the shaft rigidly or over flexible joints, and a second element is coupled by means of flexible joints with the same shaft or with another shaft. The driving mechanism can consist of one driving shaft with two crank assemblies arranged with a phase shift to one another. The flexible joints consist of flat steel springs with a width-to-thickness ratio more than 10.
