A method for applying adhesive to a strand for bonding the strand to a substrate in the production of an absorbent garment, the method comprising: supplying a strand along a path separated spatially from the substrate in a machine direction; dispensing a substantially continuous fluid adhesive fiber toward the strand in a direction normal to the machine direction; oscillating the strand back and forth in a direction orthogonal to the machine direction and in a plane substantially normal to the continuous fluid adhesive fiber across the path of the adhesive fiber as the adhesive fiber is dispensed toward the strand; capturing substantially all of the continuous fluid adhesive fiber on the strand when the strand is spatially separated from the substrate; and contacting the adhesive coated strand with the substrate to bond the adhesive-coated strand to the substrate. 15. The method of claim 14, oscillating the strand beyond the path of the fluid adhesive fiber as the fluid adhesive fiber is dispensed toward the strand, thereby forming loops of fluid adhesive fiber and wrapping the loop portions of the fluid adhesive fibers around the strand. 16. The method of claim 14, wherein the strand is an elastic strand, the substrate is a fabric for an absorbent garment, and the method further comprises stretching the elastic strand before the elastic strand is bonded to the substrate. 17. The method of claim 14, further comprising dispensing the fluid adhesive fiber from above the strand, and spatially separating the strand from the substrate by a distance greater than a droop distance of the fluid adhesive fiber below the strand where the fluid adhesive fiber is dispensed to the strand. 18. The method of claim 14, the fluid adhesive fiber is a hot melt adhesive. 19. The method of claim 14, further comprising: supplying a plurality of at least two strands along corresponding paths separated spatially from the substrate in a machine direction; dispensing a plurality of substantially continuous fluid adhesive fibers from a corresponding plurality of adhesive orifices directed toward a corresponding one of the plurality of strands in a direction substantially normal to the machine direction; oscillating each of the plurality of strands back and forth in a direction orthogonal to the machine direction and in a plane substantially normal to the fluid adhesive fibers across the path of the corresponding fluid adhesive fibers as the fluid adhesive fibers are dispensed toward the strands; capturing substantially all of each corresponding adhesive fiber on the corresponding strand when the strand is spatially separated from the substrate; and contacting the plurality of adhesive coated strands with the substrate to bond the plurality of strands to the substrate. 20. The method of claim 19, the plurality of strands are elastic strands. 21. The method of claim 19, the fluid adhesive fibers are a hot melt adhesive. 22. An apparatus for applying fluid filaments to a strand, the apparatus comprising: a dispensing nozzle for dispensing fluid filaments to a strand; a strand supplying mechanism for supplying a strand in a machine direction that is substantially normal to the path of the fluid filament dispensed from the dispensing nozzle; and a mechanism for oscillating the strand in a direction orthogonal to the machine direction and in a plane substantially normal to the path of the fluid filament. 23. The apparatus of claim 22, wherein the strand is an elastic strand. 24. The apparatus of claim 22, wherein the fluid filament is a fluid adhesive filament. 25. The apparatus of claim 24, wherein the fluid adhesive filam ent is a hot melt adhesive. 26. The apparatus of claim 22, further comprising a mechanism initiating and terminating dispensing fluid filaments at predetermined intervals. 27. The apparatus of claim 22, the dispensing nozzles having a plurality of orifices for dispensing a plurality of adhesive fibers and the strand supply mechanism having a mechanism for supplying a plurality of strands separated spatially from each other. 28. A method of making an absorbent garment comprising: providing a top sheet material, a back sheet material and an absorbent core; applying a fluid filament to a strand including supplying a strand along a machine direction; dispensing a substantially continuous fluid filament toward the strand in a direction substantially normal to the machine direction; oscillating the strand back and forth in a direction orthogonal to the machine direction and in a plane substantially normal to the continuous fluid filament fiber across the path of the fluid filament as the fluid filament is dispensed toward the strand; capturing substantially all of the continuous fluid filament on the strand; and coating all sides of the strand at least partially with the fluid filament; and disposing the fluid filament-coated strand and the absorbent core between the top sheet material and the back sheet material. 29. The method of making an absorbent garment of claim 28, wherein the strand is an elastic strand. 30. The method of making an absorbent garment of claim 28, wherein the fluid filament is a fluid adhesive filament. 31. The method of making an absorbent garment of claim 30, wherein the fluid adhesive filament is a hot melt adhesive. 32. The method of making an absorbent garment of claim 28, wherein the dispensing of the substantially continuous fluid filament is initiated and terminated at predetermined intervals. 33. The method of making an absorbent garment of claim 28, further comprising: supplying a plurality of strands separated spatially from the top sheet, back sheet, absorbent core and each other in a machine direction; dispensing a plurality of fluid filaments from a corresponding plurality of fluid filament orifices toward a corresponding one of the plurality of strands in a direction substantially normal to the machine direction; oscillating each of the plurality of strands back and forth in a direction orthogonal to the machine direction and in a plane substantially normal to the fluid filament across the path of the corresponding fluid filament as the fluid fibers are dispensed toward the strands; capturing substantially all of each fluid filament on the corresponding strand when the strand is spatially separated from the substrate; at least partially coating all sides of each strand with the corresponding fluid filament when the strand is spatially separated from the top sheet, back sheet and absorbent core; and contacting the plurality of fluid filament coated strands with at least one of the top sheet and back sheet to bond the plurality of strands therewith. 34. A method of making an absorbent garment comprising: providing a top sheet material, back sheet material, and an absorbent core wherein the absorbent core is disposed between the top sheet material and the back sheet material to form an absorbent assembly; constructing a laminate including a first substrate, a second substrate and a strand disposed between the first and second substrates wherein the strand is supplied in a machine direction along a path separated spatially from the first and second substrates, a fluid fiber is dispensed toward the strand in a direction normal to the machine direction, the strand is oscillated back and forth in a direction orthogonal to the machine direction and in a plane substantially normal to the fluid fiber across the path of the fluid fiber as the fluid fiber is dispensed toward the strand, capturing substantially all of the fluid fiber on the strand, and coating all sides of the str
