Abstract (en)
A method for making laps (15) of thermoplastic polymer continuous fibers or filaments, comprises a drawing step in which the filaments (3) are drawn on a vertical plane, by a mechanical action thereon. With respect to prior methods, the inventive method provides the advantage that it allows to continuously make a non-woven fabric having strength and ultimate elongation properties better than that of the available standard fabrics. <IMAGE>
