BROTHER S-7780A-503-32-64 (HEAVY WEIGHT) EDGE TRIMMING LOCKSTITCH INDUSTRIAL SEWING MACHINE

The Brother S-7780A-503-32-64 is a specialised lockstitch sewing machine with integrated side cutter, designed for heavy-duty edge trimming applications. Engineered for precision and performance, this machine features a 6.4mm side cutter, electronic feeding system, and a direct drive motor, making it ideal for finishing edges cleanly and efficiently during high-speed production.

At the heart of the machine is DigiFlex Feed — Brother’s revolutionary electronic feed control — which simplifies fabric handling, prevents slippage, and reduces the risk of needle breakage. Operators can easily toggle between normal sewing and cutting modes with a single-touch lever, streamlining workflow without downtime.

The machine also includes a closed oil tank with minimum lubrication, preventing oil stains on materials, and an automatic rotary thread trimmer for reliable, clean cutting. A wide waste chute ensures a clutter-free work surface and smooth operation.

As part of the NEXIO IoT-compatible series, the S-7780A allows for advanced production monitoring, data transfer, and integration into smart factory environments.
