Definitions

  • the invention relates to a method for producing a tubular bag consisting of a polyethylene / paper-polyethylene composite film, in which the composite film is removed in a clocked manner from a supply roll and shaped into a tube in a forming shoulder and as such is guided to a sealing station in which the filled Bags are formed by placing a cross seal.
  • Tubular bags made of a polyethylene / paper poly Ethylene composite film are shaped, are used in many ways.
  • tubular bags made of a polyethylene / paper-polyethylene composite film with a handle recess, which facilitates transportation.
  • tubular bags made of a polyethylene / paper-polyethylene composite film are not sufficiently stable to allow the insertion of a handle recess; such a recess would soon tear.
  • the invention has for its object to provide a method for producing a from a polyethylene / paper-polyethylene composite film, which is provided with a handle recess.
  • this object is achieved by applying a polypropylene fabric coated on both sides with polyethylene to the composite film before forming it into a tube, attaching the polypropylene fabric to the film before forming it into a tube, welding the polypropylene fabric coated on both sides with polyethylene to the composite film after molding to a tube, and punching a handle recess through the composite film and the polypropylene fabric.
  • the polypropylene fabric be pulled off an endless roll and cut off after application to the composite film.
  • a preferred embodiment is characterized in that the polypropylene fabric is attached to the composite film by thermal action.
  • polypropylene fabric be welded simultaneously with the welding of the edge sealing seam.
  • a polyethylene / paper-polyethylene composite film 10 is removed from a supply roll 12 in a clocked manner.
  • This composite film 10 is - in a known manner - formed into a bag in a shape shoulder 14. After the edge sealing seam running along the extent of the film has been welded, the bag is filled through the shaped shoulder 14 and then provided in a sealing station 16 with a transverse seam by which the individual bags are defined.
  • a polypropylene fabric pulled off from a further supply roll 20 and coated on both sides with polyethylene is placed on the composite film 10 on the composite film drawn off from the supply roll 12 and attached to it by a sealing jaw 24.
  • the tissue pulled off the roll 20 is cut off by a suitably designed device, which is only indicated schematically in the drawing by scissors.
  • the film provided with a handle reinforcement 30 made of a polypropylene fabric is guided in a conventional manner through the shape shoulder 14 to the sealing station 16.
  • the polypropylene fabric coated on both sides with polyethylene is welded to the surfaces of the polyethylene / paper-polyethylene composite film adjacent to these, this welding being easy to accomplish, since in this process only the polyethylene coating of the polypropylene fabric is used the polyethylene coating of the composite film are to be welded together.
  • a handle recess 28 is punched through the two layers of the composite film and through the polypropylene fabric and a profile seal is carried out.
  • a tubular bag made of a polyethylene / paper-polyethylene composite film can be created, which with a Handle recess is provided, which facilitates the transport of the bag.
  • the polypropylene fabric forms a grip reinforcement so that there is no fear of the bag tearing out in the grip area.
  • the polypropylene fabric can be welded simultaneously or after the edge seal seam has been welded.
  • the bag can be finished in the tubular bag machine or in a separate machine.
