Claim:
1. An apparatus for applying an elastic material along a curved path to a substrate, the apparatus comprising: a slot die applicator including a slot opening, a first lip, and a second lip, the slot opening located between the first lip and the second lip; a substrate carrier comprising: a non-compliant support surface and a compliant pattern element, wherein the compliant pattern element includes a pattern surface, and wherein the compliant pattern element protrudes outward relative to the non-compliant support surface to define a first minimum distance, R wherein the substrate carrier is positioned adjacent the slot die applicator to define a nip between the pattern surface and the slot die applicator, and wherein the substrate carrier is adapted to advance a substrate in a machine direction through the nip; and a guide adapted to control a lateral position of an elastic member advancing into the nip between the pattern surface and the slot die applicator, guide comprising a guide member and a motor; the guide member comprising a proximal end portion and a distal end portion, the proximal end portion operably connected with the motor to pivot the guide member back and forth about a pivot axis.
