1. A system for ultrasonic bonding of elastic laminates comprising:
a rotating roll having an axis of rotation and an exterior surface, the exterior surface formed radially about the axis of rotation of the rotating roll and comprising one or more roll anchoring mechanisms; and
a removable shell layer comprising one or more patterned segments configured to removably attach to at least a portion of the exterior surface of the rotating roll;
wherein the one or more roll anchoring mechanisms includes a plurality of magnets disposed at least within or on the exterior surface of the rotating roll and wherein the plurality of magnets are configured to magnetically fasten the removable shell layer to the rotating roll;
wherein the one or more patterned segments include a plurality of shell channels formed through the removable shell layer to form a pattern, and
wherein the one or more patterned segments comprise an anchoring mechanism configured to anchor and fasten each patterned segment to at least one of the one or more roll anchoring mechanisms of the rotating roll.
