The invention is a process of, and apparatus (10) for, collecting relatively straight blow spun fibers in a two-dimensional configuration. The process utilizes a venturi (40) to preclude the kinking and bending of the fibers until the fibers have substantially thermoset. A diffusion chamber (60) allows the fibers to be collected without entangling.
L'invention porte sur un procédé et un appareil (10) de recueil de fibres obtenues par étirage-soufflage dans une configuration bidimensionnelle en les maintenant sensiblement rectilignes. Le procédé recourt à un venturi (40) qui empêche le vrillage et la courbure des fibres avant leur durcissement à la chaleur. Une chambre de diffusion (60) permet de recueillir les fibres sans les emmêler.
