Method for spinning the liquid matrix (38) in electrostatic field between at least one spinning electrode (3) and against it arranged collecting electrode (4), while one of the electrodes is connected to one pole of high voltage source and the second electrode is connected to opposite pole of high voltage source or is grounded, at which the liquid matrix (38) being subject to spinning is to be found in electrostatic field on the active spinning zone (3100) of the cord (310) of the spinning means (31) of the spinning electrode (3). The active spinning zone (3100) of the cord during spinning process has a stable position towards the collecting electrode (4) and the liquid matrix (38) to the active spinning zone (3100) of the cord is delivered either by application to the active spinning zone (3100) of the cord or by motion of the cord (310) in direction of its length. The invention further relates to the device for production of nanofibres and to the spinning electrode (3), whose active spinning zone (3100) of the cord in the carrying body (32) of the spinning electrode (3) has a stable position and to the cord (310) there is assigned the device (37) for application of the liquid matrix (38) to the cord (310), which is arranged in the carrying body (32) of the spinning electrode (3).
