| 摘要 |
The invention concerns a method consisting in: a) generating a suspension of fine droplets of a binder dispersion in a given volume (9) above a fibre lap (2); b) spraying the particles (1) in said volume (9), whereby said particles (1) are coated by the binder dispersion (11) and drop on the fibre lap (2); c) and subjecting the assembly fibre lap /particle coated with the dispersion to a treatment, in particular thermal, for fixing the binder on the fibres of the lap (2). The installation comprises: a) an endless belt (5) provided with driving means; b) means for atomising (8) a binder dispersion (11) for generating a suspension of fine droplets of said dispersion in a given volume (9) above the endless belt; c) means (10) for spraying the particles (1) towards said volume (9); and d) a treating chamber (7) arranged on the path of the endless belt (5), downstream of the atomising (8) and spraying (10) means.
