The apparatus () for making a fibrous-containing and/or particle-containing nonwoven (NW) comprises a spinning unit () with a spinning head (), a forming surface () that is movable in a conveying direction (MD), and a channel () positioned between the spinning head () and the movable forming surface (), and formed between at least two transverse walls (), that extend transverse to the conveying direction (MD) and that are in the vicinity of the movable forming surface (), or that are in frictional contact with the movable forming surface (). The spinning unit () is adapted for spinning a stream of polymeric filaments or fibers (F) passing through said channel () and deposited onto said forming surface (). The apparatus further comprises supplying means () adapted for blowing at least one stream of cooling gas (C) and fibrous material and/or particles inside said channel () in the vicinity of the spinning head () and towards the stream of hot polymeric filaments or fibers (F) inside said channel (), said at least one stream of cooling gas (C) enabling simultaneously to cool the stream of hot fibers or filaments (F) produced by the spinning unit () and to transport and blow the fibrous material (M) and/or particles inside said channel () and into said stream of hot polymeric filaments or fibers (F).

Process and apparatus for producing a fibrous-containing and/or particle-containing nonwoven

The apparatus () is used for producing melt-blown fibres (MF). 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 meltblown filaments (f), and means () for blowing a hot primary gas flow (F) towards the outlet of the die head () in order to draw and attenuate the polymeric filaments (f) at the outlet of the die head, and a drawing unit () that is positioned below the die head (), and that is adapted to create an additional gas flow (F) that is oriented downstream to further draw and attenuate the meltblown filaments (f).
