Abstract
La présente invention concerne un voile de fibres (W) à répartition aléatoire comportant des particules sorbantes (P) uniformément distribuées. Pour assurer la distribution uniforme des particules sorbantes (P) dans le voile de fibres (W) à répartition aléatoire, le procédé consiste, pendant la formation du voile, à combiner dans le voile (W) les particules sorbantes (P) et les fibres (F). Ces fibres (F) sont reliées entre elles de façon à emprisonner les particules sorbantes (P) en répartition uniforme dans le voile (W). La liaison entre fibres (F) est obtenue par des adhésifs, des fibres à point de fusion bas ou par une opération d'aiguilletage. L'invention concerne également une machine de fabrication de voiles de fibres (W) à répartition aléatoire, constituée d'un mécanisme d'avant-train briseur (20), d'un mécanisme de cardage (24) des fibres, d'un appareil fournissant les fibres à l'avant-train briseur (20), d'un conduit à effet venturi (22), d'une source de particules sorbantes (P), et d'un condenseur de voile (14).
