An apparatus for producing melt blown fibres containing a fibrous material. It comprises a die head with several spinning orifices, means for extruding at least one melted polymeric material through the spinning orifices of the die head in the form of melt blown filaments, and means for blowing a hot primary gas flow towards the outlet of the die head in order to draw and attenuate the polymeric filaments at the outlet of the die head, a drawing unit that is positioned below the die head, and that is adapted to create an additional gas flow that is oriented downstream to further draw and attenuate the melt blown filaments, and a supplying means for continuously feeding a fibrous material into the polymeric filaments between the die head and drawing unit. |
