Abstract
A method for applying a fluid filament to a strand useful for bonding elastic strands to an absorbent garment is described. The strand is oscillated as it moves along an isolated path past a fixed fluid filament dispenser. The strand captures substantially all of the fluid filament, and at least partially all sides of the strand are coated with the filament. The filament coated strand may then be bonded to one or more substrates in some embodiments.
