The apparatus (1) is used for producing fibres (MF). It comprises a die head (104) with several spinning orifices, means (100, 101,102, 103) for extruding at least one melted polymeric material through the spinning orifices of the die head (104) in the form of filaments (f), and a drawing unit (105) positioned below the die head (104), and adapted to create a gas flow (F3) that is oriented downstream for drawing and attenuating the filaments (f). The drawing unit (105) is adapted to break the filaments (f) into discontinuous fibres (MF). |
