A method for assembling elastic laminates, the method comprising steps of: providing a first substrate and a second substrate, the first substrate and the second substrate, each having a width in a cross direction; advancing an elastic material to a spreader mechanism, the elastic material comprising a first edge and a second edge separated from the first edge in the cross direction by a central region; activating the elastic material by stretching the elastic material in a machine direction and/or cross direction at the spreader mechanism to a first elongation; consolidating the elastic material to a second elongation, wherein the second elongation is less than the first elongation, and wherein the elastic material remains stretched at the second elongation; and ultrasonically bonding the first substrate together with the second substrate with the elastic material in the second elongation positioned between the first substrate and the second substrate.
