Abstract
The invention relates to the distribution on a receiving device of fibers carried by a gas current. To improve the distribution, the gas current carrying the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current. The action of the gas layer results in an expansion of the current carrying the fibers. The invention is particularly useful where the fibers are received on a collecting device such as a foraminous conveyor belt, of large width.
