Introducing the NC 14" Long Arm Twin Needle Sewing Machine with Split Needle Bar — a powerful and precise French seam machine engineered for the toughest professional sewing applications. This machine is the ultimate solution for auto interiors, aircraft upholstery, marine canvas, furniture manufacturing, and any other demanding environment where precision, durability, and versatility are non-negotiable.
If you’re looking for a powerful, adaptable, and precise sewing machine capable of handling the toughest materials and most demanding design challenges, the NC 14” Long Arm Twin Needle French Seam Machine with split bar delivers. Whether you specialize in custom automotive interiors, aviation cabin builds, or high-end marine applications, this machine brings elite performance, fine detail, and total flexibility to your craft—all at a competitive price point that’s hard to ignore.
Built to Tackle the Toughest Materials
Whether you're sewing through thick leather, layered vinyl, heavy canvas, Sunbrella, Alcantara, or multi-layered foam-backed fabrics, this machine powers through it all with unmatched consistency. The 14” long arm offers ample working space, making it ideal for handling large, bulky, or oversized pieces—exactly what you need when working on door panels, seat assemblies, marine enclosures, or aviation sidewalls. Its robust compound feed mechanism ensures synchronized feeding of both top and bottom layers, eliminating slippage, puckering, or misalignment when dealing with tricky materials.
Precision French Seams, Every Time
As a dedicated French seam machine, the NC Long Arm Twin Needle delivers clean, symmetrical seams with flawless stitch definition. Whether you're running decorative double top-stitching on leather seat bolsters or producing reinforced seams in custom marine upholstery, this unit gives you the sharp, professional finish that today’s luxury clients demand. The stitch quality is consistent across material types and thicknesses, ensuring your work looks as good up close as it does from across the shop.
The Split Needle Bar Advantage
One of the standout features of this model is the split needle bar, which gives you the ability to disengage one needle for inside or outside corners, tight turns, and curved panels. This is a game-changer for auto and aviation interiors where flowing lines and complex contours are common. The split bar allows you to raise or lower each needle independently, letting you switch from twin-needle to single-needle operation on the fly—without changing machines or removing fabric from your work surface.
This flexibility saves time, reduces setup changes, and drastically improves the workflow in custom upholstery shops. When working on French seams, piping, or intricate panel work, you can now maintain continuous control without compromising stitch alignment or seam integrity.
Foot Control Knob for Seamless Adjustments
Equipped with a top-mounted foot control knob, this machine lets you raise or lower the presser foot while sewing—ideal for transitioning across seams of varying thickness, or when managing topographical changes in multi-layered projects. The ability to fine-tune foot pressure mid-sew means you maintain consistent tension and stitch quality, even when moving from flat fabric into foam-backed material, zippers, or welting. This user-friendly adjustment tool not only enhances stitch precision but also reduces operator fatigue during long production runs.
Long Arm, Endless Possibilities
The 14” long arm design opens the door to a wider range of applications, making this machine an essential asset for shops dealing with large or awkward components. Whether you’re installing French seams on full-length car door panels, sewing window enclosures for yachts, or building custom upholstery for private jets, the increased arm space gives you more freedom to maneuver and position your material without folding, forcing, or shifting.
This extended working space is particularly beneficial in aviation and marine applications, where large fabric panels are the norm. You’ll be able to lay your pieces flat, maintain clean visual lines, and execute long runs of straight or curved stitching with ease.
Designed for Professionals Who Demand More
This NC machine is not just built for performance—it’s engineered for longevity. With heavy-duty construction, precision-machined components, and a high-torque motor, it's designed to withstand daily commercial use for decades.
