Abstract (en)
Method for forming filament webs which employs a granular polymer held in storage containers and provides the following operational steps in succession: - automatic supply of polymer granules to feed a silo, - compression and melting of the polymer granules in an extruder fed by the silo, - feed of the molten material (11) to a spinning assembly (12), - spinning of the material to produce a plurality of bundles of filaments, - cooling (13) of the bundles of filaments, - aerodynamic drafting (15) and conveying of the bundles of filaments, - aspiration (21) of the bundles of filaments in correspondence with a conveyor belt (20), and - removal of web of filaments thus formed for the subsequent consolidating operations. Machine for forming filament webs according to the above method.
