Definitions

  • the invention relates to transport bags made of fabric and / or Foil material, the material consisting of two conductive Outer layers and an intermediate layer.
  • Transport bags of the type described are used for transportation bulk goods used.
  • the electrical dissipation usually for the outer layers of polyolefin fabric used are either through woven metal threads, through a metal coating e.g. with aluminum or by weaving carbonized Polyolefin threads reached.
  • a particularly favorable variant of the material for such transport bags is a sandwich construction with two outer layers made of conductive fabric, which are connected by an intermediate layer in the form of a polyolefin insert.
  • the outer layers made of conductive polypropylene fabric with a basis weight of 110 g / m 2 can be used, which have conductive polypropylene monofilament threads. Two layers of this fabric are bonded together by a polypropylene extrusion coating.
  • the transport bags according to the invention are characterized in that that the two outer layers by one or several connecting conductors protruding through the intermediate layer are connected.
  • the outer layers are one conductive fabric and the intermediate layer e.g. a Extrusion coating.
  • the connecting conductors are prefers conductive threads in the intermediate layer are embedded and conductively connect both outer layers.
  • the connecting conductors run from the bottom of the transport bag or its Outlet nozzle in the direction of the inlet nozzle of the transport bag and the conductive threads in the outer layers at least run across it.
  • Fig. 1 shows a cross section through the edge region a fabric and / or film material according to the prior art Technology.
  • Fig. 2 is an analog section through a material structure according to the invention.
  • 3 is the view a web of material and Fig. 4 a according to the invention equipped transport bag schematically in an oblique view.
  • the two outer layers 1, 2 are conductive and exist e.g. from a tissue Low pressure polyethylene or polypropylene.
  • the conductivity is by woven metal threads or by a Metal coating (e.g. with aluminum) or by weaving of carbonized polyolefin threads.
  • An example of a fabric that can be used is a polypropylene fabric with a basis weight of 110 g / m 2 .
  • the line is reached by polypropylene monofilament threads, which are carbonized.
  • the intermediate layer 3 Between the two outer layers is the intermediate layer 3, which connects the two outer layers 1 and 2 to one another, but is not itself conductive.
  • the polypropylene extrusion coating is usually laminated onto the fabric webs and the three layers are pressed together in a web shape.
  • Fig. 2 shows an analog section through sandwich fabric according to the invention.
  • the two outer layers, which are conductive as previously described are electrically connected to one another by connecting conductors 5 conductively connected, the connecting conductor Project through the intermediate layer.
  • the layer thicknesses are not to scale registered.
  • the intermediate layer 3 is preferred only very thin e.g. 30 to 45 micron.
  • the lengthways the material web running conductive threads as a connecting conductor 5 are much thicker, so that by the pressure of the pressure rollers of the manufacturing machine and by the pressure within the wound web roll a very good contact with transverse conductive Threads of the outer layers results.
  • connection conductors 5 can arbitrarily over the cross section of a material web be distributed. Either a uniform one is preferred Distribution or it along the longitudinal edges 6 of the Material web (see Fig. 3) several e.g. two conductive Longitudinal threads as a connecting conductor 5 and in the middle area a group of three or four connecting conductors arranged.
  • the middle thread group has the advantage of a better one Contact to the filler neck and outlet neck of the Transport bags.
  • Fig. 4 schematically shows an oblique view of an inventive Transport bag.
  • the web of material 3 forms the side walls of the transport bag 8 and from these material webs are also the Filler neck 9 and the outlet nozzle 10 are formed.
  • the Connecting conductor 5, in particular the middle coulter, extend into these sockets and secure thus sufficient conductivity and conductive Connecting the two outer layers of the material webs, so that any static charges through the earth connection 12th can be derived.
  • the invention is based on the illustrated embodiment not limited.
  • the conductive threads of the outer layers can be woven crosswise and lengthways.
  • the transport bag can have any desired shape and type of cut.
  • the basis weights the fabric is the carrying capacity of the transport bag adapt. Instead of fabrics, film material can also be used Find use.
  • the intermediate layer can next to the connecting properties also convey other properties, like water or air tightness.
  • the connecting ladder can e.g. also be band-shaped or of metal threads or wires are formed.
