Abstract

Official abstract text for this publication.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.

First claim

Opening claim text (preview).

We claim: 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. 2. The method of claim 1 , wherein the cooling includes flowing coolant through a coaxial channel in the second rotor.
