Definitions

  • the invention initially relates to a funnel bag, in particular a pot plant funnel made of thermoplastic film with a bottom seam.
  • Hopper bags of the type in question are often used for the transportation of plants and flowers used.
  • Bottom open funnel bags in the form of envelopes are for the Transport of cut flowers used. It is not essential that the funnel bags taper to a point, also are trapezoidal funnel bags to be understood by this.
  • the invention has for its object a funnel bag, in particular a To create pot plant funnels of the type mentioned and a method for continuous production of such a funnel bag or a pot plant funnel to propose that by a specially trained bottom seam allows significant quality improvement, especially if this funnel bag can be used to transport watered potted plants.
  • a funnel bag in particular a To create pot plant funnels of the type mentioned and a method for continuous production of such a funnel bag or a pot plant funnel to propose that by a specially trained bottom seam allows significant quality improvement, especially if this funnel bag can be used to transport watered potted plants.
  • one Device are created by a structurally simple means to a safe handling funnel bag, especially a pot plant funnel, is achieved.
  • the Bottom seam is formed by an adhesive seam.
  • Hot melt bonding is particularly useful here on, preferably from one at least between the side welds the funnel bag extends continuously, preferably transparent Adhesive tape is formed.
  • This adhesive strip can be essentially parallel extend to the bottom edge of the funnel bag or a freely selectable one Have course between the side welds, for example substantially Be V-shaped.
  • Such a funnel bag or a pot plant funnel of the aforementioned type can be procedurally according to the proposal according to the invention of two flat superimposed sheets of thermoplastic then special easy to manufacture when the two webs are in the area of a processing station be spaced at least on their edges to each other Inside of at least one of the two webs near the bottom edge the funnel bag is at least the distance between the two in a cross welding station formed side seams each bridging a funnel bag Glue is applied and then brought the two sheets back together become.
  • the bottom seam is not parallel to the to arrange the bottom edge of the funnel bag. Rather, it can do all kinds of things Take contours, for example in the form of a V, etc.
  • a device for the continuous production of funnel bags, especially pot plant funnels made of two layers of thermoplastic plastic lying flat on top of each other Processing stations in the form of punching devices and a bottom seam formation device as well as with a cross-cut welding station and a pin-on station are characterized in that the bottom seam formation device emits an adhesive, controllable encoder.
  • This is preferably equipped with an outlet nozzle, that after erecting the outer areas of the two tracks in the thereby Formed opening area retracts and at a fixed time and / or location adjustable or adjustable according to a program within this Area apply the adhesive seam to the inside of one web.
  • FIG. 1 and 2 supply rolls 1, 2 are shown, each of which a web 3, 4 made of thermoplastic, such as polypropylene or polyethylene can be deducted.
  • the upper track 3 and the lower track 4 can be with the help of a pair of feed rollers 5 in the direction of arrow 6.
  • Behind the Preferred roller pair 5 are processing stations in the form of a corner punching device 7 and a punching device 8 arranged.
  • V-shaped punchings 9 can be made in the lower web 4 in an edge region make, while using the punching device 8 suspension openings 10 in Edge area of the lower web 4 can be introduced.
  • a bottom seam connecting device 11 which in detail consists of a Adhesive (hot melt) donor 12 and an outlet nozzle 13, the Function and meaning is explained in more detail below.
  • the cross cut welding station 14 has corresponding welding tools 16, 17 which, for example, as Sweat bars or can also be designed as sweatbands. How from Figure 2 can be seen, these welding tools are at a certain angle arranged to each other.
  • funnel bags 15 can be operated by actuating the welding cutting tools 16, 17 Remove the funnel bags from the two sheets. In this process, they are Tracks held by a guide device indicated by the arrow 18. After after separation, the funnel bags, as is also known, arrive individually at one Needle station 19, which have needle stacking belts 21 on both sides.
  • FIG. 3 Details of the special design of the designed according to the invention Funnel bag 15 can be determined using FIG. 3.
  • the upper web 3 and the lower web 4 are made using the welding tools 16, 17 welded together so that side welds 25, 26 on the Funnel bags result.
  • a bottom-side edge 27 in its length is substantially smaller than an edge 28 of the funnel bag located on the filling side.
  • An adhesive strip 29 is located somewhat at a distance parallel to the bottom edge 27 arranged, which not only extends between the side welds 25 and 26, but also a little bit beyond that, offset by 180 ° lying funnel bag 15 extends.
  • These end regions 31 of the adhesive seam strip 29 serve as tearing protection.
  • FIG. 4 shows a modified embodiment of a pot plant funnel 15 shown.
  • a contour course 35 is shown essentially V-shaped. This course corresponds approximately to that of a flower pot. In this way, this is from the Surround the film web in the best possible way and this also has the advantage that no extreme stress tensions can occur.
