摘要：
Elasticated materials and articles comprising elasticated materials are disclosed. A method may comprise advancing first and second substrate materials and a stretched elastomeric strand in the machine direction. The method may further comprise advancing the first and the second substrate materials with the elastomeric strand positioned therebetween to a bonding apparatus. The bonding apparatus may comprise first and second elements forming a bonding nip. The method may further comprise oscillating the strand in a cross-machine direction and advancing the first and second substrate materials, and the strand, through the bonding nip and bonding the first and second substrate materials together with at least first and second bonds. The first and second bonds may be disposed on opposite sides of the strand and spaced apart a distance less than its un-tensioned diameter, and the first and second bonds may be located along an arcuate portion of the strand.
