Abstract:
1. A method of making a stretch laminate, the method comprising the steps of: providing a nip including nipping member, the nipping member comprising first and second coaxial and axially spaced-apart cylindrical surfaces that form a first nip region, a second nip region and a non-nip region disposed between the first nip region and the second nip region; providing a first substrate web to the nipping member, the first nip region, the non-nip region and the second nip region; simultaneously providing an elastic film to the nipping member, the first nip region, the non-nip region and the second nip region, joining the first substrate web and the elastic film in a face to face relationship at the first nip region and the second nip region with adhesive therebetween, thereby creating an intermediate laminate, wherein the intermediate laminate comprises a first tack down region created by the first nip region, a second tack down region created by the second nip region, and an activation region between the first tack down region and the second tack down region, and wherein the first substrate web and the elastic film are coextensive across the first tack down region, the activation region and the second tack down region; and mechanically activating the activation region of the intermediate laminate, thereby creating the stretch laminate.
