Claim 13:
14. An apparatus for making elastic laminates, the apparatus comprising:
a ring rolling device configured to activate an elastic material to form an activated elastic material;
a spreader mechanism comprising a first disk and a second disk canted relative to each other and adapted to stretch the activated elastic material in the cross direction to a first elongation and consolidate the activated elastic material to a second elongation to form a stretched activated elastic material, wherein the second elongation is less than the first elongation;
an anvil comprising an outer circumferential surface and adapted to rotate in a first direction about an axis of rotation, a plurality of pattern elements extending radially outward from the outer circumferential surface of the anvil, the anvil extending axially from a first end to a second end in a cross direction;
an ultrasonic horn adjacent the outer circumferential surface of the anvil, wherein the anvil and the ultrasonic horn are configured to operatively engage a first substrate and the stretched activated elastic material creating a plurality of ultrasonic bonds.
