A facility for forming a fibre batt, in particular nonwoven, provides a device for producing at least one fibre web, and a crosslapper which provides the fibre batt. The production device provides a carding drum and at least one doffer roller collecting the fibres on the drum and supplying the at least one web to at least one outfeed belt. The crosslapper provides an infeed belt for the introduction of the web in the crosslapper, which supplies the fibre batt formed of a stack of layers of the at least one web, and first control means of the profile of the thickness and/or of the area bulk density and/or of the bulk density of the web or of each web. A drafting means is arranged downstream of the outfeed belt of the production device and upstream of the infeed belt. Second control means may be provided to control drafting means.
