ABSTRACT:
An anvil system including a plurality of anvils having an interconnected cooling system. Each of the anvils has a means for acoustically insulating the anvil body from ultrasonic energy which originates from a ultrasonic horn. The insulation means may be a airspace slot essentially separating the vibrating portion of the anvil from the anvil body. The anvil may also have an adjustable sealing pattern which allows for facilitated exchange of sealing patterns. The anvil may also have a plurality of projecting pads which reduces damage to the ultrasonic sealing equipment and to the object to be sealed.
