Durkopp Adler 867 ECO

Twin Needle Automatic Lockstitch

The 867 ECO twin‑needle is a cost-efficient yet robust addition to the M‑TYPE flat‑bed lockstitch family. Designed specifically for precision in medium‑weight applications, it features a twin‑needle configuration, integrated needle‑feed, and a practical mechanical setup—ideal for industries demanding accuracy without complexity.

Twin‑needle compatibility — supports double‑line stitching for enhanced productivity and consistent seam quality.

Efficient fabric handling — triple feed system with bottom feed, needle feed, and alternating presser feet ensures neat, distortion‑free material transport.

Exceptional value — high‑performance design at an attractive price point, suitable for demanding production environments.

Hook options — choose between horizontal (L or XL) or vertical (XL or XXL) hooks, the latter offering up to 70% more bobbin thread capacity for extended runs.

Extended arm clearance — long‑arm versions available to accommodate large workpieces and improve operator access.

Enhanced visibility — built‑in, dimmable LED light brightens the work area and improves stitch accuracy.
