JACK Z7-181000 Fully Automatic Unions Feed Machine

Z7-181000 Fully Automatic Union Feed Machine - 

The Jack Z7-181000 is a heavy duty, triple- transport industrial lockstitch machine designed for sewing thick and challenging materials like leather, automotive, and multi-layer fabrics.  Equipped with an intelligent thickness sensing system. A powerful 850W motor and automatic features such as thread trimming , back tacking and programmable controls, it delivers stable, consistent stitching even across sudden thickness changes.  With its large hook, pneumatic foot lifter, and ease of operational making it ideal for demanding professional applications. 

Triple Transport 

This machine features synchronized movement of the feed dog, needle and walking feet, ensuring powerful and consistent material feeding. It is specially designed for heavy-duty applications such as automotive components (steering wheels, seats) sofas, bags, mattresses and other thick or multi layer materials. 

Artificial Intelligence 

An intergrated AI chip instantly detects changed in material thickness and resistance, sending real time data to the motor. this allows the machine to automatically increase needle penetration force and motor torque, ensuring smooth stable stitching and improved feeding efficiency even on demanding materials.

Thickness Sensor

 The built in thickness sensor detects variations in fabric height and automatically activates the second alternating sewing foot along with the additional thread tensioning system. This ensures optimal feeding consistent stitch quality and smooth performance throughout the entire seam. 

Double Alternating Sewing Feet 

Equipped with two adjustable knobs, this system allows the operator to set and switch between two alternating sewing feet. The feet can be activated automatically based on material thickness or overlap detected or manually, ensuring precision and efficiency in complex sewing tasks. 

Touch Screen Panel 

The intuitive touch screen panel uses voice guidence and clear icons to quickly and easily activate or deactivate functions such as bartack, presser foot lifter, thread trimmer and more. Lond pressing a button provides access to the function settings interface for advanced configuation and customization. 

Electronic Handwheel 

The integrated digital handwheel allows precise micrometric adjustments with simple rotation. A single click enables half stitch operation, giving the operator full control for detailed sewing and accurate stitch placement 

Function Keys 

Conveniently located on the machine head, the function keys allow quick access to frequently used operations. One key can be fully customized via the touch screen panel to perform a desired function, improving workflow and efficiency. 

850W Powerful Motor 

Equipped with the most powerful motor in its category, the Jack A2B-C  delivers 13% more power compared to competing triple-feed lockstitch machines. This ensures superior performance, consistent stitching, and reliable operation even on heavy or multilayer materials.

Pneumatic Presser Foot Lifter 

Equipped with a double-alternating pneumatic presser foot lifter, this system provides smooth, consistent lifting and lowering of the presser foot. It enhances operator efficiency and precision, especially when handling thick or multi-layer materials.

XXL Hook

The 32mm XXL hook accommodates thick threads and continuous seams with ease, offering 73% more capacity compared to the standard 2X hook type. This ensures smooth stitching and reduces thread jams, even in heavy-duty applications.
