Claims
- 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.
- 2. The laminate web of claim 1, wherein said laminate is joined by bonds in the absence of adhesive.
- 3. The laminate web of claim 1, wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 3:1.
- 4. The laminate web of claim 1, wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 10:1.
- 5. The laminate web of claim 1, wherein said first or second web comprises a nonwoven.
- 6. A laminate web having a plurality of apertures, said laminate web comprising:
a) first and second extensible webs being joined at a plurality of discrete bond sites; b) an elastic material disposed between said first and second nonwoven webs; and c) the first and second extensible webs being in fluid communication via the apertures.
- 7. The laminate web of claim 6, wherein said laminate is joined by bonds in the absence of adhesive.
- 8. The laminate web of claim 6, wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 3:1.
- 9. The laminate web of claim 6, wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 10:1.
- 10. The laminate web of claim 6, wherein said first or second extensible web comprises a nonwoven.
- 11. A disposable absorbent article comprising an elastic laminate web having a plurality of apertures, said 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.
- 12. The disposable absorbent article of claim 11, wherein said first or second extensible web comprises a nonwoven.
- 13. The disposable absorbent article of claim 11, wherein said elastic laminate web further comprises absorbent gelling material.
- 14. An article of apparel comprising an elastic laminate web having a plurality of apertures, said article 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.
- 15. The article of apparel of claim 14, wherein said first or second extensible web comprises a nonwoven.
- 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.
- 17. The method of claim 16, wherein said third web material is provided in an unapertured condition.
- 18. The method of claim 16, wherein said third web material is involved in said thermal point bonding about a perimeter of a said bond sites.
- 19. A method for forming an apertured elastomeric laminate web comprising 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; (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; and (g) stretching said bonded laminate to form apertures in the elastomeric laminate web.
- 20. The method of claim 19, wherein said first and second web materials comprise nonwoven fibers.
- 21. The method of claim 19, wherein said stretching means comprises incremental stretching.
- 22. The method of claim 19, wherein said protuberances of said thermal point bonder have an aspect ratio of between about 3 and 20.
- 23. The method of claim 19, wherein said protuberances of said thermal point bonder have an aspect ratio of 10.
