    摘要: In an improved die-nose assembly for a melt-blowing process wherein molten resin is extruded from a series of die-holes while heated gas is blown out through slots on either side of the die nose associated therewith, spacers which are movable widthwise of the die assembly are provided in the gas slots to provide effective uniformity in the gas streams across the width of the die.
