This machine features synchronized movement of the feed dog, needle and walking feet, providing powerful and even material feeding. It is specially designed for heavy-duty applications such as the production of automotive components (steering wheels, seats), sofas, bags, mattresses and other thick or multi-layer materials.
Artificial Intelligence
The built-in artificial intelligence chip instantly detects changes in material thickness and resistance, transmitting data in real time to the motor. This allows the machine to automatically increase needle piercing force and motor torque, ensuring smooth and stable sewing and improved material feed efficiency even when working with demanding materials.
Jack Z7-181000 is an adaptive heavy-duty sewing machine with a fabric edge moving function. JACK Z7 is a powerful industrial triple-feed lockstitch sewing machine designed for sewing thick and difficult materials such as leather, automotive upholstery, and multi-layer fabrics.
Equipped with an intelligent thickness detection system, a powerful 850W motor, and automatic functions such as thread trimming, tacking, and programmable control, it ensures stable and even sewing even with sudden changes in thickness.
Thanks to the large hook, pneumatic presser foot lifter, and user-friendly touch interface, the Z7 combines durability, precision, and ease of operation, making it ideal for demanding professional tasks.
The built-in thickness sensor detects fabric height changes and automatically activates the second presser foot with variable pitch, as well as an additional thread tension system. This ensures optimal fabric feeding, stable stitch quality, and smooth operation along the entire length of the seam.
Dual Alternating Presser Foot System
Equipped with two adjustment knobs, this system allows the operator to set and switch between two alternating presser feet. The feet can be activated automatically — depending on the material thickness or detected overlap — or manually, ensuring accurate feed and stable stitch quality on various fabrics.
Auxiliary Thread Tension Device
The secondary thread tension system can be activated either automatically—depending on the detected fabric thickness or overlap—or manually. This ensures optimal stitch formation and stable seam quality for a wide range of materials.
Dual Stitch Length
For corners and other complex seams requiring shorter stitches, the Jack Z7 sewing machine automatically adjusts the stitch length at the touch of a button, eliminating the need to manually adjust the dial. This ensures precision and efficiency when performing complex sewing tasks.
Touch Screen Panel
The intuitive touch panel uses voice prompts and clear icons to quickly and easily enable or disable functions such as tacking, presser foot lift, thread trimming and more. A long press of a button provides access to the function settings interface for advanced configuration and personalization.
Electronic Handwheel
The built-in digital handwheel allows for precise micrometer adjustment with a simple turn. One press activates half-stitch mode, giving the operator full control for detailed sewing and precise stitch placement.
Functional Shortcut Keys
Conveniently located on the machine head, function keys provide quick access to frequently used operations. One of the keys can be fully customized via the touch panel to perform the desired function, increasing efficiency and labor productivity.
Powerful 850W Motor
Equipped with the most powerful motor in its category, the Jack Z7 sewing machine provides 13% more power compared to competing triple-feed lockstitch machines. This guarantees superior performance, stable stitch quality and reliable operation even when working with heavy or dense fabrics.
Pneumatic Presser Foot Lifter
Equipped with a dual alternating pneumatic presser foot lifter, this system ensures smooth and even lifting and lowering of the presser foot. It increases operator efficiency and precision, especially when working with thick or multi-layer materials.
XXL Rotary Hook
The 32 mm diameter XXL hook easily accommodates thick threads and ensures continuous seams, offering 73% greater capacity compared to a standard 2X hook. This guarantees smooth sewing and reduces thread jamming even during intensive use.
This is the Jack Z7-181000 industrial heavy-duty sewing machine.
Equipped with advanced features for high-performance leather and heavy fabric processing.
