<p>The present invention relates to an arrangement for fibre-laying on a moving air-permeable conveyor path (2) fibre bodies which are comprised of at least two different layers, wherein the arrangement includes for each fibre layer a succession of air-laying units disposed sequentially in the direction of movement of the conveyor path, wherein each of the units includes means (6, 7) for passing a stream of air-borne fibres to a region above the moving conveyor path (2), means (3, 4) for generating a subpressure beneath the air-permeable conveyor path in the proximity of the region in which the stream of air-borne fibres is delivered, and means (6, 7) for shielding the stream of air-borne fibres from ambient air. According to the invention a transition region (a) into which ambient air can freely enter is provided between each pair of means (6, 7) arranged sequentially in the direction of movement, such as to delimit a stream of air-borne fibres, and the means (3, 4) which generate a subpressure beneath the air-permeable conveyor path extend beyond the fibre stream limiting means and into the transition region.</p> |
