Abstract (en)

[origin: EP0866152A1] A meltblowing die (10) includes a die tip (13) having an outwardly projecting triangular nosepiece (52) defining an apex (56) therealong, orifices spaced along the apex (56), and air holes flanking the apex. The air holes include a center air hole positioned at right angles to the apex, and air holes flanking the center air holes and positioned at an angle with respect to the apex so that fibers discharging from some of the orifices are caused to flare outwardly and increase the width of the pattern deposition. <IMAGE>
