MMVF products are made using a centrifugal spinner having a first rotor (4) and optionally other rotors (5, 6, 7) mounted on a housing (3) to form fibres which are entrained in an air stream from air supply means (8, 9, 10 and 11) and the housing (3) is oscillated during the process through an oscillation angle of 5 to 30~ about a substantially vertical axis of oscillation.
On fabrique des produits en fibre vitreuse synthétique à l'aide d'un dispositif à filer centrifuge comportant un premier rotor (4) ainsi qu'éventuellement d'autres rotors (5, 6, 7), lesquels sont montés dans un carter (3) afin de former des fibres qui sont entraînées dans un flux d'air provenant de moyens (8, 9, 10 et 11) d'alimentation en air; lors du processus de filage, on fait osciller le carter (3) selon un angle d'oscillation compris entre 5 et 30·, autour d'un axe vertical d'oscillation.
