Abstract

Procédé de fabrication d'un produit fibreux à partir de particules séparées dans lequel un flux d'air (A) est utilisé pour former un mat sur une plate-forme de formage (1) en mouvement. Lesdites particules sont liées pour former le mat à l'aide d'un liant à activation thermique apporté sur le site de formage du mat de telle façon que, lorsqu'il est activé par l'action de la chaleur, ledit liant lie les particules entre elles dans le mat. Ledit matériau liant est déjà mis en état d'activation dans un flux d'air (A) acheminant les particules sur la plate-forme de formage (1) par réglage de la température du flux d'air à un niveau suffisamment élevé. Le matériau formant la base du mat dans les particules présente une température d'activation plus élevée que le matériau liant à activation thermique.
