The LTFBA Glass Bending Furnace

Features

  • A closed, well-insulated chamber guarantees a stable, disturbance-free environment for the glass bending process
  • Extremely smooth wagon transfer has been achieved through controlling the speed with a frequency converter.
  • The heating elements located in the bending section allow precise control of the bending process
  • Automatic, vertically adjustable heaters facilitate the bending of glass units with tight radii on the folds
  • Fully automated control, based on continuous measurement of glass temperatures with an optical infrared pyrometer, maintains consistent quality, irrespective of changes in the production mix or the operator's skill
  • A manual mode is available for the production of individual items, maintenance and programming, while an automatic mode ensures minimal deviations in bending shapes.

 

The R&D generates innovations

Due to the continuous and innovative development efforts, the current product range is world-class and the furnaces manufactured contain several unique properties.

  • The control system with optical pyrometer(s) guarantees excellent repeatability of shape and easy use of the furnace, while allowing the optimization of the capacity of the furnace at the same time. The Vertically Adjustable Heating Elements, VAHE™, further enhance the repeatability of shape.
  • The patented FuzzyBend™ control system gives clear advantages for 8-10 wagon systems. It practically eliminates the effects of the changing production mix, the heat balance of the furnace, external conditions and variations in the supply voltage.
  • The heaters in the bending section can be provided with divisions of five instead of three, 5-part Heating Elements.
  • The Temperature Balancing system consisting of one extra pyrometer in the bending section guarantees symmetrical heating. The glass temperature is symmetrically measured and if variations are noted, the control system automatically balances the heating pattern.
  • Extra heating elements placed on the mould can now be divided into three parts, 3-part Extra Heating Elements.
  • Automatic Central Support consists of motors outside the furnace in the bending section and a mechanical support system in each wagon. It can support the glass or the mould depending on the system being used.
  • The loading station can be equipped with a loading device, which allows the operator to lift and flip the windscreen completely out of the wagons. It consists of 4 lifting pins in a pit under the loading/unloading area and a manual glass 'flipping' device with horizontal roller arms, the FlipFlap™.
  • The Condition Monitoring and Maintenance System (CMMS™), a preventive maintenance feature, minimizes downtime and maximizes hours of operation.
  • Glassrobots' technicians can easily communicate with the process computer via a modem with the remote diagnostic software, GlassButler™.
