Jack Sewing - Lockstitch

Digital Stitch Length

The stitch length can reach 0.1mm controlled by a stepper motor. The stitch length adjustment lock function has also been introduced.

Digital footlifter

Presser foot lifter controlled digitally by a stepper motor. Up to 13 levels can be adjusted from the panel with one click.

Jack A4S is suitable for all different types of materials

Sewing motifs

You can create beautiful ornamental stitches, thanks to the alternating length of the stitch. They can also be modified according to different needs.

Silent Bartack

Thanks to the stepper motor structure for electronic clamping, the noise has been drastically reduced: this allows you to work in a quieter and more comfortable working environment.

Short cut

There is no need to cut the remaining thread: this avoids the risk of ruining the work and saves time and money. In addition, the machine also allows you to activate the initial and/or final condensing stitch to avoid the seam from unravelling.

High Precision Overlap

Stitch overlapping can be done very precisely in all stitch lengths. Digital start and end bartack function available.
