Roper Whitney Autobrake Series

For over 20 years, Roper Whitney has been producing quality folding systems for a variety of markets. Building on that experience, the Generation "2" Autobrake integrates advanced design with the features that have made the Autobrake the choice of professionals.

The Autobrake combines automated bending of angles up to 145°, material clamping, and material support into a single CNC controlled system employing wing bending techniques.

Manufacturing, service, and applications support are based in Rockford, IL U.S.A.

Benefits of the Generation "2" Autobrake system vs. manual or press brake bending are:

  • Reduced labor costs
  • Improved part accuracy
  • Reduced setup time
  • Minimized tool changes
  • Improved part quality especially on soft and pre-painted material

The Generation "2" Autobrake is a plate and weldment steel construction, delivering superior performance and features in a simplified rigid design. End housings are a plate-type construction bringing drive components close together for improved stiffness and performance. Actuating mechanisms are secured in rigid mounts at the outside of the housings, allowing easy maintenance.

Clamping and hemming are programmed. The upper beam is driven to program settings on both ends by a brake motor and eccentric drive of the beam with a connecting shaft. Clamping and hemming power is delivered to the clamp jaws by a series of spring washers to provide variable clamping pressures with a shock-absorbing end stop. This provides reliable clamping pressure regardless of material thickness. Integral to the upper beam are the ways with non-metallic gibing to guide and retain the upper beam within the end housings.



The folding beam consists of a thick plate for maximum resistance to bending forces with a machined seat to receive the standard .787" (20mm) or the thin .390" (10mm) or .250" (7mm) bending blade. A micrometer nut setting allows adjustment for large variations in material thickness. Actuating members rotate the bending beam into position from both ends of the machine, using a variable speed drive (VSD) for accurate control over programmed bend angles. Mechanisms are mounted within reinforced connections for improved performance.

The lower beam is a welded reinforced structure fabricated of thick steel keyed into the end housings. The lower beam is pinned in place, and close-coupled to the end housings and upper beam for improved rigidity. The advanced design of this beam delivers superior hemming results in galvanized sheets.

Operating mechanisms of the Generation "2" Autobrake are enclosed within attractive end covers. Each cover is equipped with lift points for easy removal from the machine, presenting all moving parts for easy maintenance. Covers are nested on tapered mounts for easy attachment to the ends of the machine.

Part program operation and creation are accomplished on a pendant-mounted computer control, located at the right-hand side of the machine. Programs are presented in a logical organized manner similar to the steps used to create parts on traditional folding brakes, allowing an easy rapid transition to the Autobrake. The computer control can be rotated into position for best use, and can be positioned to the rear of the machine.

Programming Functions are:

  • Bend Angle
  • Gauging distance
  • Radius profile macro
  • Programmable delay for back
  • Customer alpha/numeric part number
  • Open, closed, or teardrop hemming
  • Clamping force
  • Material handling instructions
  • Programmable part counter
  • Spring back compensation
  • Offset for hem operations
  • Programmable delay for back gauge
  • Open hem height
  • Information screen for entering of part related data
  • Jaw opening
