Brother SL-777B Industrial Single Needle Lockstitch Machine with Side Cutter

Brother SL-777B Industrial Single Needle Lockstitch Sewing Machine with Side Cutter

The Brother SL-777B is an industrial single-needle straight lockstitch sewing machine with an integrated side cutter, designed for efficient sewing and edge trimming in one operation. It is suitable for medium-weight materials and is ideal for garment manufacturing, tailoring, apparel production, collars, flaps, and hem stitching.

The machine allows operators to switch between normal sewing and sewing with side cutting using an easy-to-operate lever. This provides greater flexibility and helps improve productivity during repetitive sewing operations.

Key Features

Integrated Side Cutter
The built-in side cutter trims the material edge while sewing, allowing sewing and edge cutting to be performed simultaneously.

Easy Switching Between Sewing & Cutting
The side cutter can be raised or lowered with a single-touch lever, making it easy to switch between normal lockstitch sewing and cutting operations.

High-Speed Industrial Performance
The SL-777B offers a maximum sewing speed of 4,500 stitches per minute, making it suitable for professional garment production environments.

Built-In Cutter Mechanism
The cutter drive mechanism is integrated into the machine arm, providing more working space around the needle and making material handling easier.

29.5 mm Duster Hole
Cut fabric scraps are smoothly directed through the wide 29.5 mm duster hole into the duster chute, helping keep the sewing workstation cleaner.

Can Be Used as a Standard Lockstitch Machine
When the side cutter is not required, the machine can be converted for normal lockstitch sewing by installing the appropriate needle plate cover.
