ABSTRACT:
For the manufacture of non-wovens, filaments are laid down on a moving surface. The filaments are deflected by means of a rotating deflector and a subsequent guide plate connected thereto. It is important that the rotating deflector deflects the filaments from the rotational axis and that the guide plate rotating synchronously with the deflector leads back at least part of the filaments in the direction of the intersection of the rotational axis and the deposition surface, this leading back being carried out advantageously to a different extent for different portions of the filament veil. This leading back being at least partial results in a considerably more uniform area weight distribution than hitherto obtained.
