Cylinder-Bed Power for 3D & Tubular Work

• Cylinder-bed design makes it easy to sew small, tubular and pre-assembled items such as bag bodies, straps, corners, gussets, and shoe components.
• Unison feed walking foot moves the material from the top and bottom together with the needle, preventing slipping and layer shifting on leather, vinyl, canvas, and other heavy materials.
• High fabric clearance (approx. 15 mm) allows you to easily load and maneuver bulky or multi-layer projects.
• Top feed lift around 7 mm helps climb thick seams and crossovers without losing stitch quality.

Materials & Applications

The SPEEDWAY SW-335L is ideal for medium to heavy-weight materials, including:

1. Leathercraft – handbags, wallets, straps, cases, small leather goods.
2. Bags & backpacks – side seams, bottoms, gussets, straps, reinforcements.
3. Footwear & accessories – shoe uppers, components, and leather accessories.
4. Upholstery & seating – edges, corners and curved areas on cushions and seats.
5. Canvas & technical textiles – tool rolls, covers, pouches, outdoor gear components.

Anytime you need precise stitching on tight curves or tubular shapes, the SW-335L shines.
