Abstract (en)
Method for producing a nonwoven material comprising at least one layer of continuous filaments, such as spunbond- or meltblown fibres. A first web of continuous filaments (19) are laid on a wire (14) or other permeable support member having a resilient extensibility in the transverse direction and which substantially resumes its original dimension when the extension is discontinued, that the wire is stretched in the transverse direction to at least 120% of its original width when the continuous filaments are laid on the wire. The stretching is discontinued after the continuous filaments have been laid on the wire. <IMAGE>
