Description / JACK A7-D COMPUTERISED DIGITAL FEED SINGLE NEEDLE LOCKSTICH MACHINE

Jack A7-D
- Digital Feeding Computerised Single Needle Lockstitch Machine.

Advanced single needle lockstitch machine with digital feed control, fabric thickness detection, and stitch pattern functions. Features include automatic thread trimming, digital presser foot lifter, silent bartack, short thread trimming, electric tension opener, and auto bobbin cutter. Comes with a sealed oil pan and a spacious 260mm arm.

Digital Feed Dog Movement

Offers four elliptical feed patterns tailored to different fabric types. Easily switch between Normal, Smooth, Soft, or Heavy Duty modes to ensure optimal fabric handling and stitch quality.

Fabric Thickness Detection

A built-in sensor automatically detects changes in fabric thickness and adjusts the feed dog movement in real time. This ensures consistent stitch length, even when sewing over seams or uneven surfaces.

Sewing Patterns

Create beautiful ornamental stitches using alternating stitch lengths. Patterns are fully customizable, allowing you to adjust them to suit different fabrics, styles, and sewing requirements.

Digital Stitch Length

Thanks to the advanced stepper motor controlling the bartack, the traditional mechanical lever has been eliminated. This innovation makes operation quieter and simpler, allowing easy stitch length adjustment with just the push of a button.

Silent Bartack

The electronic bartack, driven by a stepper motor, significantly reduces noise levels. This ensures a quieter, more comfortable working environment without compromising performance.

No Oil

The sealed oil pan prevents dust from entering, keeping the machine clean and durable while ensuring optimal lubrication without oil spills.

Voice Guide

The machine guides you through its functions with helpful voice instructions. If an error occurs, it notifies you and, by pressing the VOICE button, offers step-by-step suggestions to resolve the issue.

Short Thread

No more manual thread trimming—this feature prevents damage to your work and saves time and materials. Additionally, you can add initial or final locking stitches to secure seams and prevent unraveling.

Industry 4.0 (Optional)

With the integrated Wi-Fi module, you can remotely adjust machine settings and monitor productivity through a dedicated app. Note: One Jack gateway is required for every 50 machines.
