1. A method for ultrasonically bonding elastic laminates, the method comprising:
attaching a removable shell layer comprising a plurality of shell channels to form a shell pattern to at least a portion of an exterior surface of a rotating roll, the rotating roll including an axis of rotation, the exterior surface formed radially about the axis of rotation;
advancing at least a laminate material assembly comprising a pair of substrate materials with at least an elastic material positioned therebetween along a machine direction to dispose the laminate material assembly on the removable shell layer;
applying a vacuum pressure to the laminate material assembly through a plurality of roll channels of the rotating roll aligned with the plurality of shell channels of the removable shell layer to draw the laminate material assembly into the plurality of shell channels forming the shell pattern;
ultrasonically bonding the laminate material assembly to bond the pair of substrate materials and the elastic material positioned therebetween to form an elastic laminate including a laminate pattern corresponding to the shell pattern; and
advancing the elastic laminate including the laminate pattern along the machine direction.
