Apparatus for inflating tube film for manufacturing packaging material, and a method for inflating tube film with such apparatus

The invention relates to an apparatus for inflating film in situ production of packaging material, the apparatus (1) an inflating unit (2), a device for transporting the film (3), a sealing unit comprising (4 ) and means (5) for admission roll 12 film, wherein the apparatus (1) a relatively small compact device with an application area, being supplied the inflating unit (2), the transport of the film ( 3) and the sealing unit (4) in a central unit (6) in the apparatus (1) and operatively positioned relative to a center of the film to inflate and seal, seen in a direction at right angles to the transport direction the film being the film to inflate operatively engaged only in or near the very center by the central unit for inflating the film from or from near the center, and then seal the film strongly and transport, with the inflating unit (2 ) a nozzle inflator (18) comprising a rounded top at one end of the blow nozzle (18), characterized in that a downstream inside of the top (19) gradually merges into upstream longitudinal sides of the posterior and anterior refer here to a direction of normal air flow in the blow nozzle during use- and because the blow nozzle (18) there are at least two air outlet openings (- blowing nozzle (18) 20) situated in angle to the transport direction of the film (R1), such that during use - from each of said at least two holes air outlet (20) air into the film, flowing regularly in one direction (R3) that lies in the same plane with the film, and comprising a first component that is directed opposite the transport direction of the film (R1) direction, and a second component directed perpendicularly the film conveying direction (R1).
