Claim 7:
8. An apparatus for making elastic laminates, the apparatus comprising:
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 an elastic material creating a plurality of ultrasonic bonds; and
a spreader mechanism upstream of the anvil in a machine direction and adapted to stretch an advancing elastic material in the cross direction to a first elongation and consolidate the stretched elastic material to a second elongation, wherein the second elongation is less than the first elongation, wherein the spreader mechanism comprises a first disk and a second disk canted relative each other.
