EFFICIENT NECKED BONDED LAMINATES AND METHODS OF MAKING SAME

摘要

The present invention provides an elastic necked-bonded laminate material (40) or elastic neck stretched bonded laminate material including at least one necked material (12) joined to at least one elastic sheet (32) that has been stretched in the cross-machine direction and allowed to relax prior to joining with the necked material. The elastic sheet (32) can be stretched prior to being joined with the necked material or following the joining to the necked material (12). Also disclosed is a method of producing an elastic necked-bonded laminate material including the step of stretching the elastic sheet in a macroscopic stretching apparatus (18), such as between the nip of a series of spaced apart discs (71, 72) on two axles.
