  • The core cutting line model TO 45 Veloce is designed and built for the production of grain-oriented laminations suitable for the assembly of electric transformer cores with Step Lap system.  Consistently with the transformer design, this machine is particularly suitable for the production of cores for transformer power ratings ranging from 160 to 6300 KVA. 

    The cutting line is made up of machines whose co-ordination is managed by control software.

    High performance and reliability of the line ensure an high output productivity.

    The line automates the functions necessary for the processing of the laminations, namely:

    • Unwinding from the coil;
    • Measurement of the shapes;
    • Conveying and cutting of the sheet;
    • Stacking of the finished products.

    In the stacking function, various degrees of accuracy and automation can be reacheddepending on the selected model of the machine stacker.

    The main advantages of this line are:

    • Compact and solid design, small footprint
    • Energy saving
    • Direct decoiler control without loop pit, minimal infrastructural impact
    • New electronic cutting system
    • Silent working 
    • Installation flexibility, also after commissioning
    • E stacking with step-lap book management
    • 0.18 mm lamination thickness management
    • Quick commissioning
    • Column height calibration and scrap reduction
    • Management of different cores
    • Flat yoke assembly
    • Lamination FRS - Fast Replacing System
    • MES - Manufacturing Execution System
  • Foil Winding Machine BOB L 800
    Winding machine BOB L 800 is designed to wind LV coils for Distribution Transformers ranging from 100 to 3150 kVA, with one foil made of copper or aluminium.

  • Winding machine BOB L 800 is designed to wind LV coils for Distribution Transformers ranging from 100 to 3150 kVA, with one foil made of copper or aluminium.

    Main features:
    - High tensioning capability to accomplish a wider range of requirements;
    - Regenerative braking action for energy savings;
    - Electronic control of the foil tensioning and alignment;
    - Welding unit inside the frame, TIG or COLD welding;
    - Manual or fully automatic welding;
    - Stops can be programmed and executed by the machine PC;
    - A heavier coil can be loaded reducing set up times.
