The Brother SL-777B is a high-speed, industrial single-needle straight lockstitch sewing machine designed specifically with an integrated side cutter. This feature allows the machine to trim fabric edges simultaneously while sewing, making it ideal for professional garment production, particularly for collars, flaps, and hems.

Key Features
Dual Mode Functionality: You can switch between normal sewing and edge-cutting mode with a single touch using an easy-to-operate lever.
Integrated Side Cutter: The cutting mechanism is built directly into the machine arm, providing more workspace around the needle for easier material handling.
Waste Management: Features a 29.5 mm wide duster hole that smoothly conveys fabric scraps into a duster chute, keeping the workspace clean.
Versatility: By attaching a needle plate cover, the machine can be used as a standard lockstitcher when the cutter is not needed.
