Method for the production of a fiber composite by placing fibers on a support, wherein long fibers are used at least as an essential component for the production of a nonwoven fabric (70). Said fibers are fed to at least one delivery head (A, A1, A2) substantially over the height of a material column and ejected in a substantially horizontal manner therefrom. A long fiber-air suspension is generated by adding at least one aggregate. The suspension is directly applied on the support, which is especially shaped as a molding strip (14).

L'invention concerne un procédé de production d'un composite en fibres obtenu par application de fibres sur un support, des fibres longues étant utilisées au moins comme composant essentiel pour la production d'un non-tissé (70). Lesdites fibres sont conduites à au moins une tête d'extraction (A, A1, A2), au-dessus de la hauteur d'une colonne de matériau, et éjectées de cette tête d'extraction pratiquement horizontalement. Une suspension de fibres longues dans l'air est formée par addition d'au moins un additif. La suspension est directement appliquée sur le support qui se présente en particulier sous la forme d'une bande de moulage (14).
