Jack A6F Computerized Needle Feed Lockstitch Machine

This high-performance industrial sewing machine is designed for smooth, precise, and reliable sewing across a wide range of fabrics. Its needle and feed-dog feeding system ensures stable fabric control, helping prevent wrinkles, uneven feeding, and layer offset during sewing.

The machine uses advanced stepping motor technology to provide highly accurate stitch length control, with stitch length adjustment as precise as 0.1 mm. The stitch length can also be locked according to the operator's requirements, preventing accidental adjustments during operation.

With stepping motor control, the machine operates with significantly reduced noise, creating a quieter and more comfortable working environment. The reverse-stitch sound is below 20 dB, while the presser foot lifter sound is below 60 dB.

The machine produces clean and beautiful stitches, with the thread tail after sewing kept below 3 mm. Automatic thread locking helps prevent thread loosening and improves the overall finishing quality.

Its sealed oil pan helps prevent oil leakage and keeps the sewing area cleaner by protecting the internal components from impurities. The machine also features a large 300 mm operating space, making it suitable for both lightweight and bulky materials.

From shirts and chiffon fabrics to down jackets, cotton jackets, curtains, bed sheets, and duvet covers, this machine provides smooth and consistent feeding for a wide range of sewing applications.
