Apparatus for forming a fibre mat, in particular a non-woven mat, comprising a fibre web-forming device, for example a card, a cross-tapper and a device for drafting the fibre web(s) disposed between the web forming device and the cross-lapper in order to draft the fibre web(s), in particular in a time-varying, specifically periodic manner, to thereby adjust a predetermined desired profile of the fibre mat leaving the cross-lapper, the web-forming device comprising at least one output belt (1, 2) for at least one web (5, 6), and preferably two output belts (1, 2) for two webs (5, 6), an upper and lower web respectively; wherein the cross-hipper has an input belt (7) for receiving the web(s) from the output belt(s) of the web forming device, characterised in that the arrangement is such that the path of the web, or of the at least one web, and preferably of the two, upper and lower, webs, between the output belt(s) of the web-forming device, in particular the card, and the input belt of the cross-lapper includes at least one inflection point (11, 12).

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.
