A method for assembling elastic laminates, the method comprising steps of: providing a first substrate comprising a first surface and an opposing second surface, and defining a width in a cross direction; wrapping the first surface of the first substrate onto an outer circumferential surface of an anvil; providing a first elastic material and a second elastic material, the first elastic material and the second elastic material each comprising a first edge region and a second edge region separated from the first edge region in the cross direction by a central region; stretching the central region of the first elastic material in the cross direction; stretching the central region of the second elastic material in the cross direction; advancing the first elastic material onto the anvil at a first application zone, wherein the stretched central region of the first elastic material is positioned in contact with the second surface of the first substrate; advancing the second elastic material onto the anvil at a second application zone downstream of the first application zone, wherein the stretched central region of the second elastic material is positioned in contact with the second surface of the first substrate, and wherein the second elastic material is separated from the first elastic material in a cross direction; forming an elastic laminate by ultrasonically bonding the stretched central regions of the first and second elastic materials together with the first substrate; and cutting the first substrate along the machine direction.
