The Brother DB2-B7741-946 is a high-speed industrial sewing machine designed for garment and clothing materials, featuring a servo motor and reverse stitching capabilities for enhanced control and versatility. The servo motor provides precise speed regulation and energy efficiency, stopping the machine only when in use, while the reverse stitch function allows for reinforcing seams at the beginning and end of stitching lines. It's equipped with a bottom feed system, which means it may not be suitable for very thick or layered materials like car upholstery or leather, as the feeding mechanism doesn't involve a walking foot.
