Drive and Transmission

  • All units and folder are shaft driven by a DC motor , which is installed independent of the unit and folder and is located parallel to the drive shaft on folder .
  • The units are connected with torsionally rigid Thomas coupling provided on the drive shafts.
  • Units can be silenced from the main drive with the help of quick
  • coupling /decoupling arrangement.

Main Control Panel

  • Main control panel with PLC based switchgear, push buttons and all indications.
  • Analog/digital dc drives
  • Field reversal
  • Interlock /safety devices for over current, short circuit & over temperature protection
  • All systems and wiring conform to international standards

 
Operating Control Station

  • An independent free standing operator console with a master dampener control can also be offered.
  • Located conveniently near the folder for ease of operations. It consists of a modular desk for a press start up , centralized printing function controls and auxiliary equipment which includes
