Abstract (en)
[origin: EP0987352A2] A meltblowing die includes a die tip having an outwardly projecting triangular nosepiece defining an apex therealong, a row of hot melt holes spaced along the apex, and air holes positioned in relation to the hot melt holes to cause at least some of the filaments discharging therefrom to flare outwardly so that the hot melt filaments deposited on an underlying moving substrate has a lateral dimension greater than the length of the row of hot melt holes. The die may be operated to cause t he filaments to be deposited on the substrate in a side-by-side sinusoidal, stitch-like pattern. <IMAGE>
