1. A method of sealing a web body comprising:
supporting a first thermally conductive sealing jaw on a first rotor, supporting a second thermally conductive sealing jaw on a second rotor;
rotating the first and second rotors to bring the first second sealing jaws into an opposing relation in contact with the web body; and
while rotating the first and second rotors heating at least the first sealing jaw of the first rotor and cooling the second rotor, whereby transfer of heat from the first sealing jaw to the second sealing jaw is promoted.
