A real technological advance that will bring flexibility and mobilityin all production operations, thus avoiding to adjust the top rollerssupport carriages.


  • Constant pitch between consecutive points of contact withglass ribbon: Glass ribbon evenly stretched all along the forming zone
  • Shorter forming zone: Forming area more homogeneous in temperature
  • Higher process consistency: More stable top rollers support carriages
  • Easier visionic: Optimization of bath visionic system for a better process tuning
  • Improved Edge Control: Very high flexibility on ribbon spreading shape
  • Better Edge Control results in improved optical quality
