An apparatus and method for bonding at least two continuously moving substrate webs together is disclosed. The apparatus comprises a rotatable bonding roll which is located adjacent the substrate webs and configured to rotate about a bonding axis. A rotatable anvil roll has an anvil surface and is configured to rotate about an anvil axis to press the substrate webs against an outer peripheral bonding surface of the bonding roll thereby bonding the substrate webs together. The anvil roll is pivotally connected to a pivotal support mechanism which is configured to maintain the anvil surface in a substantially parallel relationship with the bonding surface. The pivotal support mechanism is configured to allow the anvil roll to pivot such that the anvil roll maintains a substantially constant force on the bonding surface of the bonding roll across the width of the anvil roll.
