Adaptive Hump-Jumping Heavy Duty Sewing Machine
The Z7 features synchronized movement of the feed dog, needle, and presser feet — engineered specifically for the heaviest materials used in automotive interiors (steering wheels, seats, etc.), furniture upholstery, bags, and mattresses. It delivers exceptional feeding precision and consistency, even under extreme workloads.
An advanced AI chip instantly detects changes in material thickness and resistance, transmitting the data to the motor. This increases penetration force and motor torque automatically, ensuring smoother sewing and superior feeding efficiency across all material types.
The built-in sensor identifies variations in fabric thickness and automatically activates the secondary alternating presser feet and additional thread tension system, guaranteeing perfect stitch quality throughout every seam.
Two adjustment knobs control a dual-interchange foot system, which can operate either automatically or manually based on detected thickness or overlapping layers.
An auxiliary thread tension unit can also be triggered automatically or manually, adapting precisely to material layers for optimal tension and stitch formation.
When sewing corners or dense seams that require shorter stitches, the Z7 automatically switches to the correct setting at the press of a button — no need to manually adjust the knob.
The intuitive touch screen with voice guide and icon interface allows you to easily activate or deactivate functions such as backtack, presser foot lift, thread trimming, and more. Long-pressing a button opens the advanced settings menu.
Perform micrometric stitch adjustments with the integrated digital handwheel — half-stitch precision with a simple click!
Conveniently positioned on the machine head, the function keys offer easy access, and one key can be customized to your preference directly from the panel.
The most powerful motor in its class — delivering 13% more torque compared to competing triple-feed lockstitch machines.
Equipped with a dual alternating pneumatic presser foot lifting system for enhanced efficiency and operator comfort.
Accommodates thick threads and long seams effortlessly with a large 32mm hook — 73% larger than standard 2X hook types, ensuring durability and performance.
