In the world of architectural metalworking—where a single gutter or facade profile can stretch up to 12 meters—standard press brakes reach their physical limits. This is the domain of Jorns AG. Founded in 1968 in Lotzwil, Switzerland, Jorns has dedicated over half a century to perfecting the art of Long-Length Bending.
Jorns is not just a machine manufacturer; they are the technical backbone of the global roofing and facade industry. When an architect designs a seamless, 10-meter long flashing for a skyscraper or a complex industrial gutter system, it is almost certainly produced on a Jorns machine. With a philosophy rooted in Swiss Precision, Jorns provides the high-performance bending lines that allow sheet metal workers to achieve perfect angles over extreme lengths with millimeter accuracy.
The Jorns Heritage: 50+ Years of Swiss Engineering
The Jorns name is synonymous with durability. In an era of “throwaway” machinery, Jorns machines are engineered for a 30-year industrial lifespan. Every component, from the massive hydraulic cylinders to the sophisticated CNC backgauges, is designed and assembled in Switzerland.
Why Jorns is the Global Standard for Long Bending:
- Extreme Length Capacity: While standard machines stop at 3 or 4 meters, Jorns excels in the 6 to 12.2-meter range.
- Large Throat Depth: Their machines offer industry-leading “Open Space” (G-shape frame), allowing for the creation of complex, deep-profile geometries that are impossible on standard press brakes.
- Precision at Scale: Maintaining a consistent angle across a 10-meter sheet of 3mm steel is a massive engineering challenge. Jorns solves this through advanced hydraulic crowning and synchronized clamping systems.

Jorns J-Bending: The Professional Choice
The Jorns J-Bending series is the workhorse for the high-end sheet metal shop. It is designed for maximum flexibility in producing flashings, gutters, and profiles.
Key Features of the J-Bending Series:
- The Servo-Hydraulic Drive: Unlike traditional systems, Jorns uses high-speed servo-hydraulics that provide maximum force with minimum energy consumption and noise.
- Infinite Clamping Pressure: The machine automatically adjusts clamping pressure based on material type and thickness, preventing “marking” on sensitive coated or painted architectural surfaces.
- Multi-Axis Backgauge: The CNC-controlled backgauge can move independently, allowing for tapered profiles (conical parts) which are essential for overlapping roof sections and drainage systems.
Jorns Twin-Bending: Doubling Productivity
The most significant innovation from Jorns in recent years is the Twin-Bending technology. This system utilizes two independent bending blades (upper and lower), allowing the machine to bend both “Up” and “Down” without flipping the sheet.
The Twin-Bending Advantage:
- No Manual Flipping: For a 10-meter long sheet, flipping the material requires two or three operators and carries a high risk of material damage or injury. The Twin-Bender eliminates this entirely.
- Complex Profiles: Profiles with “Z” or “S” shapes can be completed in a single sequence, doubling the output speed of the workshop.
- Automatic Tool Positioning: The machine automatically calculates the optimal tool position for each bend, ensuring that the “hem” or “drip edge” is perfect every time.
Architectural Profiles: Facades, Gutters, and Flashings
Jorns machines are specifically engineered for the Building Envelope sector.
- Facades: Large-scale cassette panels and interlocking facade profiles require absolute linearity. Jorns machines ensure that these panels fit together perfectly on-site, reducing installation time.
- Roofing & Gutters: From standard “U” shapes to complex ornamental gutters, the large throat depth (up to 1250mm) of Jorns machines provides the freedom to innovate in roof design.
- Conical Bending: By angling the backgauge, Jorns allows for the production of profiles that “nest” into one another, providing a leak-proof seal for long-run roofing projects.
Software Intelligence: J-Touch and CP200
In 2026, a Jorns machine is a “Smart Partner” in the digital workshop.
- J-Touch Control: A high-definition, intuitive touchscreen interface that allows operators to “draw” the profile directly on the screen. The software then automatically calculates the bending sequence and backgauge positions.
- Automatic Bend Sequencing: The CNC analyzes the part geometry to prevent collisions with the machine frame, suggesting the most efficient path for production.
- Remote Support: Jorns technical teams can log into the machine’s control system from Switzerland to perform diagnostics, ensuring that a project in Turkey or Australia never misses a deadline.

7. Sector-Specific Applications
Jorns technology is the “invisible architect” in these key sectors:
- Industrial Warehousing: Producing massive lengths of roof ridge caps and corner flashings.
- Commercial Skyscrapers: High-precision facade cassettes that define the modern city skyline.
- Rainwater Systems: Automated production of seamless gutters and downspouts.
- Agriculture: Long-span panels for barns, silos, and storage facilities.
8. Sustainability: Building for the Future
Jorns is committed to Resource-Efficient Manufacturing:
- Servo-Hydraulic Efficiency: Their modern drive systems reduce energy consumption by up to 30% compared to traditional hydraulics.
- Material Optimization: Accurate bending from the “first part” reduces scrap, which is especially critical when working with expensive coated aluminum or copper.
- Enduring Value: Because Jorns machines last for decades, their “Carbon Footprint per Year of Service” is significantly lower than cheaper, low-durability alternatives.
Training and Global Support
Jorns operates with a philosophy of “Partnership for Life.”
- The Jorns Academy: Specialized training for profile designers and machine operators to master the complexities of 3D profile simulation.
- Global Service Network: Through partners like Durmark, Jorns ensures that local expertise and original spare parts are always available in the Turkish and Middle Eastern markets.
- Refurbishment Programs: Jorns offers “Retrofit” kits for older machines, allowing 20-year-old frames to be updated with modern CNC controls and safety systems.
Fully Automated Bending Cells
Looking toward 2027, Jorns is pioneering the Fully Automated Long-Length Cell. This involves integrating the Jorns Twin-Bender with a specialized “Sheet Loading Robot” and an “Automatic Stacking System.” This move toward a “Zero-Touch” long-bending process will allow factories to produce hundreds of meters of profile daily with a single supervisor.
