Patent attributes
A method for assembling elastic laminates includes the steps of stretching an elastic film at a spreader mechanism in the cross direction to a first elongation; advancing the elastic film from the spreader mechanism to an anvil, wherein the anvil comprises an active vacuum zone having a maximum width in the cross direction of Wv. The maximum width is divided into a first portion and a second portion, wherein the first portion is disposed in overlapping relationship with the engagement portion and inboard of the engagement portion in the cross direction and the first portion has a width in the cross direction of VZi and wherein the second portion has a width in the cross direction of VZo, and wherein a ratio of VZi is greater than to VZo is greater than 1.
