Definitions

  • the present invention relates to packaging machines and more particularly to former shoulders which receive film from a roll to transform the film into a tubular configuration for delivery to a machine which forms discrete packages containing product.
  • Packaging machines such as those described in USA Patents 4663917, 4423858, 4391081, 3070931 and 3850780 employ formers which transform plastic film (strip) into a tubular configuration.
  • the film is pulled through the former by means of a film drive unit.
  • the film drive unit will engage the tubular material by means of rollers and belts such as that discussed in USA Patent 4910943. It is also known to move the tubular bag material through the packaging machines by means of engagement with the jaws of the packaging machine.
  • a former includes a forming shoulder over which the film passes. Problems are often encountered with this relative movement which can result in a variation in the force required to move the film over and through the former. Preferably the force required is constant and is not excessive. These problems are exacerbated in the case of heavy gauge film as well as film that may be relatively stiff. Humidity and static charge also influence the force required to be applied to the film.
  • a further problem to the above is that frequently formers will smudge any printed material applied to the film.
  • a shoulder for a packaging machine former said shoulder including:
  • the said passage terminates with an aperture located generally centrally in said surface.
  • said shoulder further includes a valve to deliver said gas to said passage, said valve being adapted to govern the pressure of said gas delivered to said surface.
  • FIG. 1 there is schematically depicted a former apparatus 10 through which a web of film 11 passes to be formed into a tube 12.
  • the tube 12 passes through a packaging machine and receives a product which is to be packaged by the packaging machine.
  • the product to be packaged is delivered to the upper aperture 13 of the tube 12, with the tube 12 being subsequently scaled along the back seam and at spaced locations to form discrete packages.
  • the apparatus 10 includes a base 14 which supports a shoulder 15 over which the film 11 passes.
  • the shoulder 15 includes an approach member 16 which leads to a crown 17 over which the film 11 passes to be configured to form the tube 12.
  • the member 16 has an upper surface 18 past which the film 11 moves in its passage to the crown 17.
  • the film 11 is removed from a roll and first engages a roller 19 before delivery to the surface 18,
  • the member 16 is provided with a passage 20 terminating at its end with a generally centrally located aperture 21.
  • the aperture 21 is in the surface 18.
  • Extending from the passage 20 is a duct 22 communicating with an airflow control valve 23.
  • the valve 23 receives a gas (typically air) under pressure.
  • the valve 23 governs delivery of air to the passage 20 and therefore the aperture 21.
  • Air leaving the aperture 21 enters an area 24 between the surface 18 and film 11. This aids movement of the film 11 over the surface 18 by creating an "air cushion" over which the film 11 passes. This reduces frictional engagement between the surface 18 and the film 11.
  • the air escapes laterally relative to the longitudinal direction 25 of movement of the film 11.
  • a duct 26 Extending from the valve 23 is a duct 26 which attaches the apparatus 10 to a supply of gas under pressure.
  • the flow of gas could be pulsed if so required.
  • the gas could be heated or chilled to increase or decrease the stiffness of the film 11.
  • heating of the film 11 may aid in the drying of ink.
  • one or more apertures 21 are formed in the surface 18, each with an associated passage 20 extending from the duct 22
