<p>A sealing jaw assembly has a capacitor (162) mounted thereon and a sealing jaw (130) including sealing inductor formed from Litz wire. Thus, the sealing jaw assembly includes the tank circuit for the sealing jaw. The sealing jaw assembly is mounted on a sealing jaw chassis (172) which, in turn, is mounted on a carriage arranged to move around a track. The sealing jaw employs an air gap transformer which includes a primary transformer winding mounted on a fixed surface and a secondary transformer winding (174) mounted on the sealing jaw chassis (172). As the sealing jaw carriage moves around the track, the secondary transformer winding (174) comes into proximity with the primary transformer winding, whereupon a current is induced in the sealing inductor of the sealing jaw.</p> |
