BROTHER SL-777B-32-3.2MM EDGE TRIMMING LOCKSTITCH INDUSTRIAL SEWING MACHINE

The Brother SL-777B-32-3.2MM is a reliable and efficient lockstitch sewing machine built for medium-weight materials, featuring an integrated 3.2mm side cutter for precise edge trimming. This model is ideal for operations such as collar construction, flap sewing, and hemming, combining cutting and stitching in one seamless process.

With its easy one-touch cutter control, operators can quickly switch between normal sewing and trimming without stopping the workflow. The cutter drive mechanism is built into the machine arm, providing more room around the needle for better material handling and operator comfort.

A 29.5mm wide duster hole effectively clears away material scraps through the duster chute, maintaining a tidy sewing surface. When edge trimming isn’t required, the side cutter can be deactivated, and the machine functions as a conventional lockstitcher with the included needle plate cover.
