BROTHER SL-777B-32-4.8MM EDGE TRIMMING LOCKSTITCH INDUSTRIAL SEWING MACHINE

The Brother SL-777B-32-4.8MM is a high-speed lockstitch industrial sewing machine with an integrated 4.8mm side cutter, ideal for collars, flaps, hems, and general edge-trimming applications on medium-weight materials. This model provides a compact and efficient solution for combining cutting and stitching into one smooth operation.

Operators can switch between trimming and standard sewing instantly using the easy one-touch side cutter lever. The cutter drive mechanism is built into the arm, providing more space around the needle for easier fabric handling and operator comfort.

The machine also features a 29.5mm wide duster hole, which keeps the sewing area clear by efficiently removing scrap material. When not in use, the side cutter can be disengaged, and the machine can function as a standard straight lockstitcher using the included needle plate cover.
