DELTA e-con energy-efficient design: Saves up to 25 % power compared with comparable digital machines while raising sewing performance.

Fully digitalised control: Integrated drive and digitally programmable setting elements deliver precise, reproducible results and support advanced process optimisation.

Medium-heavy capability: Sophisticated sewing kinematics handle demanding materials and complex seams with consistency.

Programmable parameters: Electronic adjustment of key settings such as thread tension, foot stroke and needle positioning enhances process control.

Industry 4.0 readiness: Modular interfaces and flexible connectivity simplify integration with external automation, Poka-Yoke systems and production networks.

Intuitive operation: Advanced control panel (Commander DELTA) with multi-touch interface reduces setup and teach-in time.

Cylinder design: Narrow arm geometry improves accessibility for tubular or hard-to-reach workpieces.

Reproducibility and sustainability: DELTA e-con supports higher productivity with fewer resource demands, contributing to lower operating costs and environmental impact.

Key Features & Benefits

E-CON – efficient, energy-saving and sustainable sewing

Perfect sewing results thanks to optimised sewing kinematics – even in demanding materials.

Intuitive operation and up to 30% shorter teach-in times due to the multi-touch control panel.

Automatic optimisation of sewing parameters during the sewing process via integrated Material Thickness Detection (MTD).

Efficiency and reproducibility using program-supported sewing and electronic control elements.

Flexible and future-oriented – the digital sewing system for the future.

Outstanding performance parameters - Up to 3000 stitches/minute (subclass-dependent), optimised working area due to increased clearance of 350 mm x 128 mm and simultaneously reduced machine footprint.

The DELTA platform – a wide range of models, equipment and fields of application.

Personalized to your individual needs - Starting with the right height of the table top, your individual control panel configuration or your user profile that gives you access to exactly those areas that are relevant and useful for you.

Solid cast core in an innovative and service-friendly design.
