Jack A6F-E-PK – Digital Needle Feed Lockstitch Machine with Integrated PK Puller
The Jack A6F-E-PK is a high-tech automatic lockstitch machine designed for medium-weight fabrics, combining precision, durability, and advanced automation. Thanks to its double transport system (needle feed + feed dog) and the integrated PK puller, this machine guarantees perfect fabric handling, even for layered or slippery textiles. The extended arm (30 cm) provides more space for large sewing projects, making it ideal for industrial applications where efficiency and stitch quality are essential.
Key features include the digital stitch length system (adjustable in 0.1 mm increments), silent bartack, ornamental stitch motifs, and an innovative voice guide for user support. The machine is also equipped with a semi-dry lubrication system with a sealed oil pan, protecting fabrics from staining and extending machine life.
