  1. Production of agricultural tyres

  2. Production of agricultural tyres Components of an agricultural radial tyre Tread (Cap) Tread (Base) Belt plies(dark blue) Casing plies(light blue) Sidewall Inner lining(brown) Core profile Bead protection flap (yellow) Flange profile Core

  3. Production of agricultural tyres Main componentsof an agriculturaltyre: Natural andsyntheticrubber 51 % Fillers(carbonblack, carbon, crayon, etc.) 28 % Stabilitycomponentsfrom syntheticfibre (Polyamid/Nylon, Polyester, Rayon/Viskose, Aramid/Kevlar) or steel 7 % Different chemicals (Oil, Fat, Wax, Sulphur, etc.) 13 % Others 1 %

  4. Production of agricultural tyres Chemical industry Textile industry Steel industry Extraction of natural rubber Rolls of textile cord Rolls of steel cord Rolls of core wire Manufacturing the basic compound Extrusion of sidewall strip Tread extruder Calendering the inner lining Textile cord calender Steel cord calender Coating the core wire Cooling the tread strip Cutting the textile cord to size Cutting the steel cord to size Coiling the core wire Cutting the tread strip to size bead ring

  5. Production of agricultural tyres Assembly Assembling the casing Assembling the belt and tread Vulcanisation Spraying the green tyre Vulcanisation Quality control Final check Checking true running X-ray check

  23. Preparation / Semi: production of the bead core Core profile (appex) Core machine Completed bead core Core flag (flipper)

  24. Preparation / Semi: transport carriage for other profiles „Buchwagen“ (carriage for treads)

  25. Tyre building: Bias Tyre building machine Tyre building, Casing plies are wrapped around the building drum

  26. Tyre building: Bias Side view of the building drum Bias green body with casing plies, beads, sidewalls and tread, „Green Tyre“ (ton body)

  27. Tyre building: Radial 1st stage Tyre building, Casing plies are wrapped around the building drum Radial green body after 1st stage with carcasse, beads and sidewalls

  28. Tyre building: Radial 2nd stage Tyre building mashine 2nd stage Radial tyres Expansion of the green body to predefined dimension

  29. Tyre building: Radial 2nd stage Belt plies are applied Tread is applied to the green body

  30. Tyre building: Radial 2nd stage Tread is wrapped around the green body

  31. Tyre building: Radial Orbitread process For bigger tyres the tread is applied mechanically

  32. Tyre building: Radial Orbitread process Orbitread machine
