ABSTRACT:
A method for producing a shaped non-woven comprises the steps of feeding fibers on a carding machine over a limited width, superposing on a receiving system the fibrous web leaving the carding machine and needling the superposed layers. The superposition is preferably obtained by winding over a cylindrical drain.
The shaped non-woven obtained has a thickness gradually decreasing towards its selvedges. The obtained strip has a cross-section of an asymmetrical shape by longitudinal cutting along the median axis and optionally two longitudinal cuttings on the selvedge side.
