Power, Feeding & Stitch Quality

• Twin-needle needle feed: the needle helps pull the fabric together with the feed dogs, reducing layer shifting and puckering—especially important on slippery or multi-layer materials.
• Large-capacity bobbins: double large Japanese hooks increase under-thread capacity, so operators spend less time stopping to change bobbins.
• Servo motor included: quiet, energy-saving motor with excellent low-speed control for precise cornering and topstitching.
• Consistent stitch formation at production speeds, ideal for long straight runs and visible seams.

Materials & Applications

The SPEEDWAY SW-872 is designed for medium-weight materials and a wide variety of industrial applications, including:

1. Garments & workwear – parallel topstitching on seams, yokes, waistbands, plackets and pockets.
2. Denim & casualwear – twin-needle decorative seams on jeans, jackets and skirts (within medium-weight range).
3. Uniforms & corporate wear – strong, clean, symmetrical stitch lines on trousers, shirts and jackets.
4. Light upholstery & automotive trim – panels, covers and decorative twin seams on medium fabrics.
5. Bags & accessories – straps, handles, edges and visible topstitching on canvas, twill and similar materials.

Wherever you need two parallel rows of lockstitch that look straight, strong and professional, the SW-872 is the right tool.
