Abstract
At least two machines placed side by side, including a series of centrifuging wheels arranged in a cascaded manner and driven in rotation about axes all having substantially in a same direction. Two consecutive wheels rotate in opposite directions, and are simultaneously fed with material to be fiberized. The material is poured onto the first wheel, is accelerated, and is conveyed onto the second wheel, and then optionally onto following wheels, in order to be converted into fibers by centrifugal ejection, the fibers being picked up by a gas stream and collected by a gathering device. The main axes of two adjacent machines are positioned along a non-zero angle adjusted in order for two gas streams emitted by the two adjacent machines to meet and combine. Such machines may find application in the manufacture of products based on mineral fibers.
