Elastic laminate web
First Claim
1. A non-apertured elastic laminate web comprising:
- a) a first web;
b) a second web joined to said first web in a face to face relationship at a plurality of discrete bond sites having an aspect ratio of at least 2, the first and second webs forming an interior region therebetween;
c) an elastic material being disposed between at least a portion of said first and second webs; and
d) said elastic material being apertured in regions coincident said bond sites, such that said first and second webs are joined through said apertures.

Abstract
An elastic laminate web is disclosed. The elastic laminate web can be non-apertured or apertured, and comprises a first web, and a second web joined to the first web in a face to face relationship at a plurality of discrete bond sites having an aspect ratio of at least 2. The first and second webs form an interior region therebetween. An elastic material is disposed between the first and second webs. The elastic material is apertured in regions coincident the bond sites, such that the first and second webs are joined through the apertures. The laminate so produced can be stretched in a predetermined direction, such as by incremental stretching, to produce an apertured elastic laminate.

16. A method for forming an elastic laminate web the steps of:
-
(a) providing first and second web materials comprising thermoplastic material;
(b) providing at least one third elastomeric web material;
(c) providing a thermal point bonder having a plurality of protuberances;
(d) guiding said third elastomeric web material in a stretched condition between at least a portion of said first and second web materials in a face-to-face layered relationship to said thermal point bonder;
(e) displacing said third elastomeric web material with said protuberances at discrete, spaced apart locations to form apertures in said third material; and
(f) thermally point bonding said first and second outer web materials to form bond sites at discrete, spaced apart locations coincident with said protuberances, thereby forming a bonded laminate.
