Abstract (en)

In an apparatus (1) for the production of a non-woven fabric of filaments, a plurality of filaments (5) are extruded from at least one spinneret (2), and are cooled in a cooling chamber (4) by at least one flow of air. Advantageously, the cooling chamber (4) is provided with at least one wall (12) opening to make available to the filaments (5) an alternative path that allows the side disposal of the filaments (5) of discarded products during the transitory starting period of the apparatus (1). The filaments laterally diverted are collected in containers or collection areas by means of adjustable draught units.
