The invention relates to the device for production of nanofibres through electrostatic spinning of polymer matrices in electrostatic field of high intensity induced through difference of potentials between the spinning electrode (3) and the collecting electrode (4), which comprises the cylindric body (41), while the nanofibres are deposited on the substrate material (5) conducted between the spinning electrode (3) and collecting electrode (4). The cylindric body (41) of collecting electrode is mounted rotatably coincidently to direction of motion of substrate material (5). The cylindric body (41) may be provided with the tips (416). L'invention concerne un dispositif de production de nanofibres par filage électrostatique de matrices de polymères dans un champ électrostatique de haute intensité induit par une différence de potentiels entre l'électrode de filage (3) et l'électrode collectrice (4), qui comporte le corps cylindrique (41), tandis que les nanofibres sont déposées sur le matériau de substrat (5) placé entre l'électrode de filage (3) et l'électrode collectrice (4). Le corps cylindrique (41) de l'électrode collectrice est monté de manière rotative et coïncidente dans la direction de mouvement du matériau de substrat (5). Le corps cylindrique (41) peut être pourvu des extrémités (416).
