Abstract
An installation for consolidating a batt of fibers, for example a nonwoven web, includes a mechanical consolidation workstation using needlepunching from which the fiber batt emerges in a machine or MD direction. A device is provided downstream of the consolidation workstation for stretching in the cross or CD direction which is transverse, in particular perpendicular, to the machine direction, and parallel to the plane of the batt, particularly before it is wound onto a reel. A consolidated nonwoven that can be obtained by the installation is also provided.
