Abstract
A method of manufacturing an elasticized composite material including a multiplicity of elastic strips for use in garments, particularly in disposable absorbent articles is disclosed. The method includes the steps of folding the first substrate around the mandrel to form a tube while moving the tube longitudinally at a first velocity, and simultaneously winding at least one elastic strip around an outer surface of the tube at a second velocity to form a helical path. The elastic strip can be joined to the outer surface of the tube along the helical path to form a first composite tube. The method further includes the step of folding a second substrate around the first composite tube to cover the elastic strip and to form a second composite tube, which then can be slit longitudinally to form a planar composite material. Finally, the planar composite material can be activated to form the elasticized composite material.
