Abstract: Spinning nozzle for production of nanofibrous and microfibrous materials comprises: a first plate (1) provided with at least one continuous groove (2) for directing a first material to an outlet mouth portion (3) of the continuous groove (2) in a face (4) of the first plate (1); a second plate (5) provided with at least one continuous groove (6) for directing a second material to an outlet mouth portion (7) of the continuous groove (6) of the second plate (5), the outlet mouth portion (7) being arranged adjacent to the outlet mouth portion (3) of the first plate (1); and a separating plate (8) arranged between the first plate (1) and the second plate (5) for separating the continuous grooves (2) of the first plate (1) from the continuous grooves (6) of the second plate (5), while the face (9) of the separating plate (8) forms with the face (4) of the first plate (1) and/or the face (10) of the second plate (5) a continuous surface in the region of the outlet mouth portions (3; 7) of the continuous grooves (2;

Abstract: The combined spinning nozzle for the production of nanofibrous or microfibrous materials comprises a thin-walled electrode (1) and a first non-conductive body (2) adjoining the first wall of said thin-walled electrode, said first body having its wall, which faces the thin-walled electrode (1), provided with an array of grooves (5) formed therein, said grooves leading to the distal end (6) of the combined spinning nozzle and having their proximal ends connected to a supply of spinning mixture. The thin-walled electrode (1) and the first non-conductive body (2) may assume either plate-like or cylindrical shapes. The combined spinning nozzle may further comprise a second non-conductive body (4) adjoining a second wall of the thin-walled electrode (1) and directing the air from the proximal end towards the distal end (6) of the nozzle.
