20190269565 · 2019-09-05 ·

A method of forming a disposable product includes feeding an incoming web of ear material, engaging the web with a rotating anvil, cutting ears from the web via the rotating anvil and interaction thereof with a corresponding die, so as to form pairs of ears having complimentary and nested ear shapes, and coupling the ears to at least one of a wing and a web of chassis material. In feeding the incoming web of ear material, the speed of the web is selectively varied between at least a first speed and a second speed, with the web being fed to the rotating die and anvil at the first speed to result in the cut ear shapes having a first height and the web being fed to the rotating die and anvil at the second speed to result in the cut ear shapes having a second height.
