A method of producing a fibrous product is disclosed. Molten material is introduced into a rotating spinner (12) which includes a peripheral wall having a plurality of orifices. The molten material is centrifuged through the orifices to create fibers (20). The fibers are directed generally downwardly and away from the spinner. The fibers are intercepted on a collector so that the fibers are draped over the collector. The fibers form first and second suspended portions (52,54) which are oriented generally vertically. The collector and intercepted fibers are moved away from the spinner. The first and second portions of the suspended fibers are raised to a generally horizontal orientation, thereby producing a generally planar fibrous product (28).

Méthode de fabrication d'un produit fibreux. Du matériel en fusion est introduit dans un fileur rotatif (12) dont la paroi périphérique est dotée d'une pluralité d'orifices. Par centrifugation, le matériel en fusion passe à travers les orifices pour produire des fibres (20). Ces fibres sont généralement dirigées vers le bas en s'éloignant du fileur. Les fibres sont interceptées par un collecteur sur lequel elle sont étalées. Les fibres forment une première et une seconde portions suspendues (52, 54) qui sont généralement orientées à la verticale. Le collecteur et les fibres sont écartés du fileur. La première et la seconde portions de fibres suspendues sont soulevées en suivant une orientation généralement horizontale pour ainsi produire un produit fibreux généralement planaire (28).
