  • Tapeless seal bar assembly
    Patent number: 6789371
    Abstract: A packaging machine including a seal bar assembly for bonding layers of polymeric material together about a wrapped product to form an airtight package seal comprises a length of SILVERSTONE encapsulated, flat electrical resistance heating ribbon disposed upon a rigid seal bar having a smooth face surface. The seal bar is preferably constructed of thermally conductive and electrically insulating materials, such as virgin TEFLON. The heating ribbon is mounted onto the seal bar under nearly constant tension throughout its temperature range. Low resistance electrical leads provide a path for supplying electricity to the heating ribbon. A silicon rubber-backed seal bar mating assembly for providing pressure to the polymeric materials during bonding is disclosed.
