  • Patent number: 7017323
    Abstract: A packaging machine for wrapping packing pieces with packing film. The packing machine includes a transport device for the packing pieces arranged in a transport channel, at least one pulling device for the packing film and a film cutting and welding device which, when operated, pulls one film section from the pulling device and welds it to another film section for forming a film tube surrounding the packing piece. The packing machine is design to prevent a run-up of the film pulled by the pulling device into the transport channel by the inclusion of a narrow through gap for the packing film. The gap limits the passage of the film when the tension on the film is reduced.
