Patent ID: 8007484

Claim:
A method of making a pants type undergarment, the method comprising the steps of : a. providing an outer nonwoven layer; b. providing a second non-woven layer; c. providing a layer of elastomeric material; d. stretching said layer of elastomeric material at a first time; e. perforating said layer of elastomeric material to form a two-dimensional perforation array of slits on said layer of elastomeric material and stretching said layer of elastomeric material at a second time; f. applying intermittent adhesive to said second non-woven layer to create a first and second zone of adhesion, and a zone of non-adhesion; g. coupling said stretched and perforated layer of elastomeric material with said second non-woven layer forming a side panel assembly; h. slitting said side panel assembly into a front portion and a rear portion; i. partially cutting said side panel assembly; j. removing said elastomeric material from said side panel assembly in said zone of non-adhesion and coupling said slit and partially cut side panel assembly with said outer non-woven layer in two separate positions on said pants type undergarment, said front portion placed at a first position extending widthwise substantially across a front waist portion of said undergarment, and said rear portion at a second position extending widthwise substantially across a rear waist portion of said undergarment; said front and rear portions each comprising a first zone of elasticity and a second zone of elasticity, with a third zone of inelasticity formed between said first and second zones.
