The NB-7T Upper and Lower Feeding Lockstitch Machine Series is an advanced Industrial Sewing Machine designed to deliver precision, durability, and high-speed performance for a wide range of garment manufacturing needs. Built with a focus on Efficiency and Speed, this model combines upper and lower fabric feeding technology with a direct-drive Servo Motor, ensuring smooth operation and professional results across different fabric types.
The NB-7T series is engineered to handle thin, medium, and heavy garment materials with equal ease. Its upper and lower feeding system ensures consistent fabric movement, preventing slippage and misalignment, which is especially important for layered or heavy-duty sewing tasks. The machine is equipped with a high-efficiency direct-drive servo motor, delivering quiet, stable operation while significantly reducing power consumption. Compared with traditional strap-driven machines, the NB-7T can save over 70% in electricity, lowering production costs and contributing to environmental sustainability.
The spacious work area offers ample room for handling large fabric pieces, while precise needle stop positioning—either up or down—ensures accuracy in every stitch. The differential feed design enhances stitch quality, making it ideal for cotton cloth, trousers, and other heavy-duty overlock sewing applications. With reduced noise levels and improved wear resistance, the NB-7T ensures long-term reliable operation in demanding production environments.
The NB-7T Upper and Lower Feeding Lockstitch Machine is perfect for professional garment production lines that require versatility and high output. It excels in manufacturing trousers, jackets, and various cotton-based garments, as well as in applications requiring reinforced seams and decorative finishes. Its stable feeding system makes it suitable for multi-layered fabrics, denim, workwear, and uniforms, where precise stitching is critical. The combination of speed, power savings, and reliable stitch formation makes this machine a valuable asset for manufacturers aiming to increase throughput without sacrificing quality.
