Roper Whitney Sheet Metal Folders | Auto Brake AB1014K Kombi Series

Roper Whitney Autobrake Kombi Series

Kombi Autobrake

For over 40 years, Roper Whitney has been producing quality folding systems for a variety of markets. Building on that experience, the newest generation Autobrake folders integrate advanced wing bending 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 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 Roper Whitney 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.

The unique rotating Kombi beam allows for straight tooling and Box and Pan tooling. It is a fabricated structural prism on which is mounted tooling to firmly clamp a broad range of materials, close hems, and withstand the forces generated by capacity forming operations. Machined into the Kombi beam 180° from each other are the attachment surfaces for the straight and box and pan tooling. Tools are attached to the Kombi beam with standard socket head cap screws. Grooves are provided to secure tools even while the clamping bars are loosened for adjustment. Rotation of the Kombi beam is powered by a brake motor driving a sprocket and roller chain mechanism.

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.

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.

Bend Angle
Gauging distance
Spring back compensation
Offsets for hem operations
Radius profile macro gauge
Programmable delay for back
Customer alpha/numeric part number
Open hem height
Open, closed, or teardrop hemming entering of part

Optional Features For The Autobrake Automated Wing Bender Folder:

  • 4" Tall Upper Beam Sectional Tooling
    • The unique Kombi beam is a fabricated structural prism on which is mounted
      tooling to firmly clamp a broad range of materials and withstand the forces
      generated by capacity forming operations. Machined into the Kombi beam 180¡
      from each other are the attachment surfaces for the straight and box and pan
      tooling. Tools are attached to the Kombi beam with standard socket head cap screws
      and grooves are provided to secure the tools even while the clamping bars are loosened
      for adjustment. Rotation of the Kombi beam is powered by a brake motor driving a sprocket
      and roller chain mechanism.
  • Several Backgauge Configurations Including:
    • U-Shaped Backgauge Extension
      • The U-shaped 12? backgauge system is simply a right and left backgauge extension
        taking your total backgauge dimension out to 144". This option can be mounted on any
        61" backgauge and can also be added to machine already in the field.
    • Left Or Right Hand 12' Backgauge Extension
      • The 12' foot backgauge extension can be added to any 61" backgauge and will extend your
        total gauging out to 144". This feature can be added at any time and can be retrofitted to
        machines that are already in the field. The backgage extension can be mounted on either the
        right or left side but needs to be specified when it is ordered.
    • Complete 12' Backgauge
    • The optional complete 12' backgauging system has to be specified prior to ordering an Autobrake.
      This system consists of a complete backgauge table that is 12' in depth as well as 12' in width.
  • 61 inch Sheet Metal Backgauge
    • 60" ball screw backgauge offering a larger backgauge
      depth as well as the capability to extend the backgauge to 10'
  • Squaring Arm For Small Or Narrow Parts
    • A squaring arm can be added to any backgauge to help in gauging narrow parts.
      The squaring arm mounts on the side of the backgauge and allows the operator to
      use one or backgauge fingers to accurately gauge narrow pieces.
  • Laser Scanner
    • The optional laser scanner is a programmable safety system that scans the entire front
      side of the Autobrake. This unit is mounted under the machine and offers more security
      than light curtains.
  • Hardened Tooling
    • Tooling for the Autobrake can be laser hardened for more durability. This option is only
      recommended when all stainless steel or pieces with plasma cut edges are run on the machine

Roper Whitney Kombi Series W/ ECS Controls




The ECS 904 system enhances the skills of the sheet metal fabricator by providing the means to quickly transfer the operator's knowledge into useful part programs.
Windows-based software is combined with a powerful machine controller, specifically designed for the Autobrake. This system delivers a high powered stable solution for all folding needs.

The ECS 904 software comes packaged within an Intel® Pentium® computer combined with a 15” flat panel display for high speed system response, and easy viewing of the operator interface. The computer system is pre-configured for connection to an inter-office network.

The computer is housed within a sealed oil-tight enclosure to prevent dust and water contamination. The front of the enclosure hinges open with the computer attached, giving access to the USB, serial, and network connections.

Computer specifications are:

15" high resolution anti-glare flat panel touch screen
Integrated industrial computer with internal air cooling
Intel Pentium-M 1.6 gigahertz processor or greater
512 megabytes of RAM memory
64 megabytes of video RAM
40.0 gigabyte hard drive
RS232 serial ports
Ethernet ready
USB 2.0 ports
Sealed oil-tight enclosure
Windows XP-Pro operating system

The ECS Control integrates the operation of the positioning gauge, bending leaf, and clamping mechanisms, and has the capability to store over one million part programs.


The ECS 904 system provides greater flexibility to the operator with fewer keystrokes, resulting in a user interface that is easy to learn, and increases productivity.

Creation of part programs can be done by text entry in the main operations screen, or part profiles can be drawn and converted into programs. Both part programs and drawings can be stored on the computer's hard drive for future use. Part profile drawings are created in vector format, allowing the part to change its shape and size dynamically as bend angles and line lengths are altered. Parts can then be visually verified as correct prior to creating the part program. Bends can be inserted, deleted, or altered as the operator desires. Therefore, stored profiles can be changed into other types of shapes on demand. Hem and radius macros can also be used to create architectural shapes, or other curved forms.

Part programs and drawings are stored and accessed from the memory using a flexible Windows based file handling system. Programs can be stored in any number of directories for easy organization according to any factors desired, such as: customer name, product name, part type, etc. Program file names can be any combination of letters or numbers, allowing programs to be identified by part form, company part number, or any other criteria desired. Programs created using the drawing portion of the Titan system show a small picture of the part for quick program identification. Incorporated into the file system is a quick search tool that allows programs to be displayed by key portions of their names. This limits the selections displayed, and speeds program access for the operator.

The control system includes several backup features. The setup parameters that control the operation of the Autobrake can be stored at any time to a file name. These settings can then be retrieved as needed to maintain correct machine performance. This provides a fast secure method to reestablish the parameter settings due to any disruption. Once per month the operator is reminded to make a complete backup of the Titan software system. This backup stores all of the critical system settings, part programs, and part profile drawings present in the Titan operation directory. Each backup made is stored separate from the next, providing a history that can be accessed if needed, and preserving the operator's part programs. Backups are placed in a USB flash drive connected to the computer control head, or may be directed to another drive; either local or network.
