Abstract:
A method for forming an article, said method comprising:a moving of a strand of material along an appointed machine-direction; a directing of a first, substantially continuous filament of adhesive onto said strand of material along an oscillating filament path, said filament forming a first plurality of filament threads disposed at opposed lateral side regions of said strand of material; a directing of at least a second, substantially continuous filament of adhesive onto said strand of material along an oscillating filament path, said filament forming a second plurality of filament threads disposed at opposed lateral side regions of said strand of material; and a directing of at least one air stream to operatively wrap said filament threads around said strand of material and thereby deposit and wrap at least about 75 wt % of said first and second filaments of adhesive onto said strand of material; wherein the directing of said first, substantially continuous filament of adhesive onto said strand of material occurs at a first nozzle location, the directing of the second, substantially continuous filament of adhesive onto said strand of material occurs at a second nozzle location, and said first and second nozzle locations are spaced apart along said machine-direction by a selected, nozzle separation distance; said nozzle separation distance is at least about 2 mm and not more than about 900 mm; the directing of said at least one air stream provides a first air stream to operatively wrap said first plurality of filament threads around said strand of material, and provides a second air stream to operatively wrap said second plurality of filament threads around said strand of material; and said first and second nozzle locations are spaced apart along a transverse cross-direction by a selected, nozzle offset distance which is not more than about 3 mm.
