  • Sealing assembly
    Publication number: 20050109444
    Abstract: For a vertical form, fill, and seal machine, the motion profile of the sealing jaws is controlled to reduce turbulence of fluid in the tube thereby promoting a better seal. Additionally, the jaws have an endless stroke so that a consistent sealing pressure may be achieved even after the jaws have worn down with repeated use.
