A method for producing mineral fibers (16) includes centrifuging mineral fibers (16) from one or more rotary mineral fiber spinners (10) to establish one or more downwardly moving veils (22) of mineral fibers (16) positioned above a collecting surface (12), centrifuging organic fibers (34) from molten organic material (32) using one or more rotary organic fiber spinners (24) to establish one or more downwardly moving veils (38) of organic fibers (34) positioned above the collecting surface (12), the veils (22) of mineral fibers (16) being generally collinear with the veils (38) of organic fibers (34), the veils (38) of organic fibers (34) alternating with the veils (22) of mineral fibers (16) to integrate the organic material and the mineral fibers (16), and collecting the integrated organic material and mineral fibers (44) on the collecting surface (12).

Selon un procédé de production de fibres minérales (16), on produit par centrifugation des fibres minérales (16) en utilisant un ou plusieurs métiers à filer rotatifs (10) de fibres minérales de façon à créer un ou plusieurs voiles descendants (22) de fibres minérales (16) situés au-dessus d'une surface de collecte (12). On produit des fibres organiques (34) par centrifugation d'un matériau organique fondu (32) en utilisant un ou plusieurs métiers à filer rotatifs (24) de fibres organiques de façon à créer un ou plusieurs voiles descendants (38) de fibres organiques (34) situés au-dessus de la surface de collecte (12). Les voiles (22) de fibres minérales (16) s'étendent généralement dans la même direction que les voiles (38) de fibres organiques (34) et les voiles (38) de fibres organiques (34) alternent avec les voiles (22) de fibres minérales (16) de façon à intégrer les matériaux organiques dans les fibres minérales (16). Finalement, on recueille les matériaux organiques et fibres minérales associés (44) sur la surface de collecte (12).
