  • This conveyor belt is suitable, for example, for the transport of glass at a temperature of over 500 ° C and up to 800 or 900 ° C.
  • Such a conveyor belt which is subjected to tensile forces and is guided over rollers, firstly has to withstand the tensile and bending forces which occur during mechanical conveyance, and secondly has to withstand the high temperatures of the transported glasses.

  • the conveyor belt according to the invention has the advantage that it has both a high heat resistance and a high maximum tensile force in which a thermally insulating middle layer is arranged between the heat-resistant cover layer and the tensile layer.
  • This insulating middle layer influences the temperature distribution in the conveyor belt in such a way that the cover layer can be at a high temperature, whereas excessive heating of the tension layer is prevented by the insulating effect.
  • the warp threads of the cover layer consist of metal fibers
  • the warp threads of the insulating middle layer consist of a high-temperature glass yarn or a silicate yarn, in particular a high-temperature glass fiber yarn or a silicate fiber yarn

  • the warp threads of the cover layer consist of pure metal fibers.
  • the insulating middle layer has the advantage that the high-strength but heat-sensitive yarn of the tension layer is protected against high temperatures or against carbonization, which ensures long-term tensile strength of the high-strength yarn.
  • the three different fabric layers are held together by a self-bond.
  • the warp threads of the three different fabric layers are arranged so that they run in the conveyor belt in such a way that all fabric layers are thereby without additional Strings are held together.

  • the three different fabric layers are held together by an additional binding chain.
  • the warp threads of the cover layer consist of metal wire, which in a particularly advantageous embodiment form loops protruding from the surface of the conveyor belt and thus form, for example, a terry-cloth-like surface structure. Since a metal wire is considerably less expensive than a metal fiber yarn, the use of a metal wire for the warp threads of the cover layer makes it possible to produce a cheaper conveyor belt.
  • a weft thread made of a metal fiber yarn or a mixed yarn made of metal fibers and aramid fibers is preferably used to bind the warp threads.
  • a metal fiber yarn preferably consists solely of metal fibers.
  • the mixed yarn consists, for example, of aramid and a V2A steel (stainless steel), and has, for example, a metal content of 90% and an aramid content of 10%.

  • the weft 4 of all five Fabric layers are made of the same material. In order to achieve a high thermal resistance between the heat-resistant cover layer 1 and the tension layer 3, the five fabric layers are held together by self-binding, in that the warp threads of the five fabric layers partially engage in an adjacent fabric layer and loop their weft thread 4, as shown at position ld is.
  • a high thermal resistance between the cover layer 1 and the tension layer 3 is of central importance in order to protect the high-strength yarn 3a, 3b, 3c used in the tension layer 3 from a high temperature.
