Durkopp Adler D869 e-con
Medium-Heavy Duty Cylinder Arm
A high-performance DELTA e-con cylinder arm sewing machine designed for demanding medium- to heavy-duty applications. The D869 e-con combines Dürkopp Adler’s proven cylinder arm platform with fully digitalised DELTA drive technology, delivering powerful penetration, precise stitch formation and energy-efficient operation for complex, three-dimensional workpieces.
DELTA e-con drive technology: Fully digitalised, energy-efficient drive concept delivering high performance with reduced power consumption.
Cylinder arm design: Slim arm geometry provides excellent access for tubular, pre-assembled and three-dimensional products.
Medium- to heavy-duty capability: High penetration power and optimised kinematics ensure consistent stitch quality on thick and dense materials.
Digitally programmable machine settings: Electronic adjustment of sewing parameters such as stitch length, foot stroke and thread tension for reproducible results.
Excellent material handling: Stable feeding and high sewing reliability across varying material thicknesses.
Intuitive operator control: Modern DELTA control panel enables fast setup, clear operation and reduced training time.
Cylinder design: Narrow arm geometry improves accessibility for tubular or hard-to-reach workpieces.
Industry 4.0 ready: Designed for connected production environments with data transparency and future automation in mind.
Sustainable production: Lower energy consumption and optimised processes help reduce 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 2800 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.
