Abstract
The invention concerns an installation for producing a spunbonded fabric web comprising a diffuser defining for the filaments a passage with diverging cross-section, and mounted a certain distance from the slot attenuator, and a conveyor for receiving the filaments coming out of the diffuser. The uniformity of the web is enhanced by means of a device separating the filaments by electrostatic process mounted at a higher level than the bottom of the passage.
