Abstract
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.
