Abstract
A method for the formation of mineral fibers in which the material to be fibered is poured in the molten state onto the peripheral surface of the first of a series of centrifuging wheels rotating at high speed in order to be fibered there by centrifugal force. The fibers formed by the various centrifuging wheels are entrained in streams of gas emitted in the immediate vicinity of the said wheels in a direction essentially parallel with the axes of rotation of the wheels. At least one of these streams of gas is emitted at a temperature of between 250.degree. and 900.degree. C. and preferably between 300.degree. and 600.degree. C., and even more preferably around 500.degree. C.
