Description
Single-needle heavy-duty unison feed walking foot — alternative platform to the SW-1510L family. Triple-feed system with vertical-axis large hook, built for the same heavy upholstery and leather work but on a different mechanical lineage.
Who runs this
Same audience as the SW-1510L: upholstery shops, leather goods manufacturers, marine canvas operations. The SW-4400N is the base model in a different walking-foot family — same heavy-duty spec, slightly different mechanical layout.
Why two families? Production shops standardizing on one platform sometimes pick based on operator training, parts availability, or familiarity. The SW-4400 family extends to longer-arm variants (L18, L25, L30) for oversized work that the SW-1510L family doesn't cover.
What sets the 4400 platform apart
- Vertical-axis large hook. Different hook orientation than the SW-1510L horizontal large hook. Same heavy-thread capacity (V138 production), different timing geometry.
- Triple unison feed. Bottom feed dog, needle feed, walking foot — the same three feed surfaces as the SW-1510L. Same slip-resistance on heavy multi-layer materials.
- Long-arm extensions available. The SW-4400-L18 (18" arm), L25 (25"), L30 (30") extend the same platform for oversized work — boat covers, industrial covers, aircraft interiors. The base SW-4400N is the 18-inch-and-under-bench-space pick.
Application examples
Auto upholstery
Three-layer leather + foam + canvas headliner with #138 bonded nylon. Same work as the SW-1510L; pick based on shop standardization.
Marine canvas
18-oz Sunbrella seam construction. Triple feed prevents slippage on UV-stabilized polyester.
Bag manufacturing
Reinforced cordura nylon tactical and travel bags. Heavy webbing handles attached without slippage.
What ships with it
Machine assembled with servo motor, industrial table, machine stand. Vertical-axis large hook installed.
