Advantages of the FFThemtec Twinstep Seamless integration into your production process.
Reduced process time
- two hemming steps are carried out in one robot movement due to the successive hemming rollers
Quality improvement
- High quality thanks to rigid system for pre-hemming and spring-loaded system for final hemming
- Component quality and tolerances can be influenced via robot program
Standardized modular system
- The TwinStep 100 and TwinStep 200 can be used in various combinations
- The hemming heads can be adapted to specific project requirements
Robust and easy to maintain
- Use of proven components for high reliability and easy spare parts procurement.
- Low maintenance requirements to minimize downtimes.

FFTmetrology HemQC
3D detection of the seam quality
FFTmetrology HemQC inspects the quality of the folded edge during the roll folding process. This is a scanning procedure in which the width and height of the fold or the excess adhesive is measured.
FFThemtec 180°
Roller hemming head for flange opening angles of up to 180
The roller hemming head FFThemtec 180° is a versatile, robot-guided tool with 1-5 hemming rollers. It is used for sunroof hemming, pre-hemming processes and hemming without backing. This hemming head can be used robot-guided or stationary.
FFThemtec VersoMP
Pneumatically Driven Manual Wheel Arch Hemming System
The FFThemtec VersoMP Roller Hemming System enables efficient prototype development and small batch production for sidewalls and wheel arches. The pneumatic head is also available with a hand crank and is operated manually.
FFThemtec VersoM / ML
Manual Wheel Arch Hemming System
The FFThemtec VersoM / VersoML Roll Hemming System is ideal for prototyping and small batches. It is manually operated and has a hand-cranked or pneumatic roller hemming head and a special hemming frame.
FFThemtec VersoA
Automated Wheel Arch Hemming System VersoA2 / VersoA4
The roller hemming system is used in automated production systems for side walls and wheel arches. It consists of a roller hemming head and a special hemming frame. Aavailable as a one- or two-robot system.
FFThemtec Verso
Uniform folding force thanks to the counter roller principle
The FFThemtec Verso roller hemming head is a robot-guided tool with up to four pairs of hemming rollers.Ideal for wheel arch and door entry hemming, it ensures uniform hemming force thanks to the counter roller principle. Flexible for various derivatives.
FFThemtec Twinstep
Processing multiple derivatives with Twinstep100 / 200
The FFThemtec Twinstep is a robot-guided tool for producing a wide variety of hemming geometries for steel and aluminum components. With two hemming rollers running one behind the other, it makes it possible to process several derivatives efficiently.
FFThemtec Single
robot-guided roller hemming head in S / F / Y / SA versions
The modular FFThemtec Single is a flexible, robot-guided roller hemming tool for flat, drop, wedge and special folds made of steel and aluminum, which easily serves multiple derivatives in one production line.
FFThemtec Roller Cleaner
Automated roller cleaner
The Roller Cleaner automates the cleaning of hemming rolls without interrupting the process. A robot positions the hemming roller in front of the drive element.
The roller is minimally wetted with oil, and a scraper removes the sticking glue.
