Split Needle Bar for Corners & Angles

• Organized split needle bar mechanism allows you to lift or disengage one needle while the other continues sewing.
• Perfect for L-shaped seams, corners, angle transitions and shape outlines, where one row needs to continue while the second row stops.
• Greatly reduces the need for stopping, re-hooping or switching to a single-needle machine when negotiating corners.
• Maintains parallel alignment and consistent spacing between rows, even when one needle is temporarily disabled for turning.

Needle Feed for Stable, Clean Seams

• Needle feed system moves the fabric in sync with the needle and feed dog, reducing slippage and puckering on multi-layer or slippery materials.
• Ensures that both needle lines feed evenly, which is essential for visible double-needle topstitching.
• Uses regular hooks, making parts and maintenance straightforward and cost-effective.
• Max stitch length 5 mm gives you flexibility for both structural seams and decorative double rows.

Materials & Applications

The SPEEDWAY SW-845 is designed for medium to heavy-weight materials, making it ideal for:

1. Garments & workwear – double-needle topstitching on seams, yokes, pockets, plackets and waistbands.
2. Uniforms & corporate wear – strong, clean, symmetrical twin-needle seams with crisp corners and angles.
3. Denim & casualwear – decorative double-needle seams on jeans, jackets and skirts (within medium/heavy fabric range).
4. Bags & accessories – straps, handles, panels, and visible topstitching where corners and angles are part of the design.
5. Light upholstery & soft goods – covers, panels, trims and components requiring neat twin seams.

Whenever you need two precise rows of stitching with the ability to handle corners and angles cleanly, the SW-845 is the right tool.
