The Jack A4F is a computerized single-needle lockstitch sewing machine designed for medium-weight fabrics. It features a digital presser foot, digital stitch adjustment, automatic thread trimmer, digital bartacking, and short thread trimming. The machine's oil pan is detached, ensuring a cleaner working environment.

Why Choose the Jack A4F?

  • Digital Stitch Length: Stitch length can be adjusted in 0.1mm increments, controlled by a stepper motor. The stitch length adjustment lock function prevents accidental changes.

  • Pattern Sewing: Create ornamental stitches with alternating stitch lengths and repetitions, which can be modified according to different needs.
