  • Tubular bag machine having a device for keeping the inside of a flexible film tube free from dust in its sealing region
    Patent number: 5581984
    Abstract: A tubular bag machine has between a filling tube and a shaping tube at least two sealing elements, which divide an annular space, formed by the filling tube and shaping tube, into a feed channel and a suction-removal channel. The two channels are connected to a suction device with a filter by connecting lines. The design and arrangement of the sealing elements produce a closed circuit for the air or inert gas used for dust removal.
