ABSTRACT:
An apparatus for producing spun-bond webs has, beneath the receiving belt, a suction unit having at least two suction zones including a primary suction zone and at least one other suction zone, the primary suction zone receiving most of the filaments from an aerodynamic stretching unit below a spinneret. The suction speeds in the two zones can be adjusted independently of one another. Preferably three such zones are provided in succession in the direction of displacement of the perforated belt.
