A meltblowing method and apparatus for dispensing an adhesive through a plurality of first orifices of a die assembly fabricated from a plurality of laminated members to form a plurality of adhesive flows at a first velocity, and dispensing air through a plurality of second orifices in the die assembly to form a plurality of air flows at a second velocity. The plurality of first and second orifices arranged in an alternating series so that each of the plurality of first orifices is flanked on substantially opposing sides by one of the plurality of second orifices, wherein the plurality of first and second orifices are oriented to direct non-convergently the plurality of adhesive flows and the plurality of air flows. The plurality of adhesive flows are drawn and attenuated by the plurality of air flows at the second velocity greater than the first velocity of the plurality of adhesive flows, wherein the plurality of adhesive flows are attenuated to form a plurality of adhesive filaments useable for the production of bodily fluid absorbing hygienic articles.
