Automated Twin Head Bender TH38
The Winton Automatic Twin Head Bender is an automated square tube fabrication center that combines bundle loading, weld seam detection, robotic transfer, simultaneous twin-head bending, and programmable part offload in one integrated system.
The system is designed for manufacturers producing high-volume square tube parts used in products such as gate doors, guard rails, handrails, commercial structures, industrial assemblies, construction products, and other tubular fabricated components.
For manufacturers evaluating ROI, the system can help track the information needed to compare the automated process against manual or semi-automatic bending. This may include part cycle time, part-count, station performance, weld seam detection results, and maintenance- related indicators. These data points can help teams evaluate labor reduction, throughput, consistency, and equipment utilization.

A More Automated Way to Process Square Tubing
Many manufacturers currently produce square tube parts using manual or semi-manual bending processes. An operator may need to load each tube, locate the weld seam, position the tube correctly, make the bend, unload the part, and move it to the next operation.
The Winton Automatic Twin Head Bender is designed to reduce that manual handling.
The system can take square tube from a bundle loader, locate the weld seam, transfer the tube into the bender, make two bends simultaneously, and eject the completed bent part onto a discharge cart or rack.
This helps manufacturers improve consistency, reduce operator-dependent steps, and move toward a more automated tube fabrication process.
How the Automatic Twin Head Bender Works
From bundle loading to finished part ejection, the system is designed to automate key handling, positioning, and bending steps.
Bundle Loading
The machine can be configured with a bundle loader for square tubing. Tubes are loaded into the system, where a series of “dogs” on a moving belt transfers tubes into the process. Protective side plates help prevent tubes from shifting during transfer.
Weld Seam Detection
For applications where weld seam location matters, the system can be equipped with a laser seam detector. The tube is rotated so the system can find and orient the weld seam before bending, improving repeatability and reducing reliance on operator judgment.
Tube Centering
Before bending, the tube is centered using a tube centering device with electrical interlocks.
Cartesian Robot Transfer
A two-axis Cartesian robot transfers the square tube from the loading and seam detection process into the twin head bender.
Simultaneous Twin-Head Bending
Two independent programmable bends are made simultaneously. Each bend head is programmable, and the system can produce bends up to 90 degrees plus spring back.
Automatic Part Ejection
After bending, the finished part is ejected onto a customer-supplied discharge rack or optional discharge cart.
Built for Square Tube Manufacturing
This system is specifically configured for square tubing, where weld seam position, part orientation, loading, unloading, and material handling are often highly operator-dependent.
By automating the process from bundle loading through bent-part discharge, manufacturers can improve consistency while reducing manual handling throughout production.

Modular Automation Opportunities
The Automatic Twin Head Bender can be part of a larger automated tube fabrication process. Depending on the application, additional operations such as punching before bending, robot interlocking, or downstream automation may be incorporated.
This modular approach can help reduce manual handling, improve flow through the factory, and move labor to areas where people are needed most.
Built for Production Safety
The machine includes multiple safety features designed for industrial manufacturing environments, including:
Customizable for Tube Diameter Requirements
The standard system is designed around a targeted tubing range, designed for high-volume tube production.
However, Winton can customize the tube magazine loader and automatic tube feeding system configuration for different tubing diameter requirements and production needs.
Because high-volume automated tube production is often dedicated to a specific tubing size or narrow diameter range, systems are typically designed for repeatable production within a targeted range.
Frequently Asked Questions
What is the Winton Automatic Twin Head Bender?
The Winton Automatic Twin Head Bender is an automated tube fabrication center that can load square tubing, detect the weld seam, transfer the tube with a Cartesian robot, make two programmable bends simultaneously, and eject the finished part.
What makes this automated twin head bender different?
This system is configured for square tubing and can include bundle loading, weld seam
detection, robotic transfer, simultaneous bending, and programmable offload. Many twin head bending applications are traditionally round tube or manually loaded; this system helps automate more of the square tube process.
How does weld seam detection help with square tube bending?
The optional laser seam detector finds and orients the weld seam before bending. This helps reduce operator-dependent variation and supports more consistent part processing.
Why does weld seam detection matter?
When bending welded tubing, weld seam position can affect consistency. The optional laser seam detector allows the system to find and position the weld seam before bending so the part is processed more consistently.
Can the machine be configured with punching before bending?
Depending on the application, additional operations such as punching may be incorporated before bending.
Can the machine make two bends at the same time?
Yes. The machine makes two independent programmable bends simultaneously. The maximum bend angle is 90 degrees plus spring back.
Does the machine support production tracking?
Yes. The PLC-controlled system includes a touch screen user interface, parts counter,
diagnostics, and production-related data that can help operators monitor performance.
Is the system fully lights-out?
The system helps move manufacturers toward a more automated process by reducing manual loading, weld seam positioning, bending, and offload steps. Operator involvement may still be required for loading bundles, removing carts, and supporting the production process.
What information should I provide Winton with for an application review?
Provide the tube shape and size, wall thickness, material, part length, bend angle, distance between bends, weld-seam requirements, current process, desired cycle time, loading requirements, offload requirements, downstream operations, and a part drawing when available.
