Abstract
In the production of a solidified nonwoven web by crosslaying a card web produced with a uniform transverse profile by a card web forming device and then by consolidating the crosslaid nonwoven web thus formed, the basis weight of the solidified nonwoven web or of the crosslaid nonwoven web is measured only in the middle and in the area of at least one of its edges, and the basis weight of the card web to be laid is locally changed on the basis of a comparison of the measurement values with the nominal values preestablished by the laws, previously described for the nonwoven web to be produced, governing the structural change in the product caused by solidifying.
