A method for applying an elastic material along a curved path to a substrate, the method comprising the steps of: advancing a substrate to a substrate carrier, the substrate having a first surface disposed opposite of a second surface; engaging the first surface of the substrate with the substrate carrier, the substrate carrier comprising: a non-compliant support surface and a pattern element, the pattern element including a pattern surface, the substrate carrier positioned adjacent a slot die applicator to define a nip between the pattern surface of the pattern element and the slot die applicator; positioning an elastic material on the second surface of the substrate; advancing the second surface of the substrate and the elastic material in a machine direction through the nip while moving the elastic material in a cross direction substantially transverse to the machine direction; and intermittently deflecting the pattern surface toward the non-compliant support surface by advancing the substrate and the elastic material through the nip.
