A melt-blowing system and corresponding method are provided for making a nonwoven polymer filament blanket. Subsequent to formation and blowing of the polymer filaments toward a receiving conveyor, a pivoting oscillating member is provided through which the filaments are blown. Vertical oscillation of the oscillating member causes the flow direction of the filament stream to vertically oscillate thereby increasing the tensile strength of the nonwoven blanket in the in-line direction as a substantial number of the filaments become oriented in the in-line direction on the conveyor.
Un système de fusion-soufflage et la méthode correspondante sont offerts pour fabriquer un mat non tissé de filaments polymériques. Après la formation et le soufflage des filaments polymériques vers une bande transporteuse de réception, les filaments sont soufflés à travers un élément oscillant pivotant. L'oscillation verticale de l'élément oscillant fait en sorte que le sens d'écoulement du courant de filaments oscille verticalement, ce qui accroît la résistance à la traction du mat non tissé dans le sens machine du fait qu'un nombre substantiel de filaments deviennent orientés dans le sens machine sur la bande transporteuse.
