Servo Roll Feeder

NC SERVO FEEDER / SERVO ROLL FEEDER

Press Room Automation was the first Indian manufacturer to recognize the potential of the new technology of servo-driven press feeding equipment (NC Servo Feeder) in 2001. Press Room Automation has redesigned and simplified its entire Servo Roll Feeder line, employing innovative, new manufacturing techniques to bring you the highest quality, lowest maintenance, most economical servo line ever.

  • Fast job changeover.
  • Compact and simple to install.
  • High production rates.

  • Servo-driven feed rolls grip and move material rapidly and precisely into a stamping press or automation operation. Press Room Automation includes user-friendly features at no extra charge—quick-release handles to adjust roller stock guides, exit support and stock buckle bridge, transition mounting brackets, positive pilot release, and roll release for material insertion via pneumatic cylinder are just a few of our standard features. All Press Room Automation Servo Roll Feeder models have extra-large rolls to withstand the toughest abuse and harshest pressroom environments. Compare our rated specifications and generous roll diameter against any other feed builder.
