ABSTRACT:
The present invention provides a method of achieving selectively elasticized zones on nonwoven web substrates, such as may be suitable for the waistbands of disposable absorbent pant garments, cuffs on sleeves of medical garments, or the like. A web, or webs, of nonwoven material which make up the substrate for the elasticized area are provided to be inherently extendable in the transverse, or lateral, direction of the material web at the time the elastic material is affixed to the substrate. If the elastic material is affixed in an untensioned state, a flat waistband without gathering of the substrate may be had for a very efficient seal against the skin of the wearer. If the elastic material is affixed to the substrate in a tensioned state, a waist band with gathering of the substrate may be had to allow for two-stage expansion via the gathers and the expansion of the substrate.
