Jack Z7-181000 Fully Automatic Walking Foot Needle Feed Sewing Machine

Unison Feed (Triple Transport) Heavy-Duty Industrial Lockstitch Machine

The Jack Z7-181000 Fully Automatic Unison Feed Industrial Sewing Machine, also known as a walking foot needle feed sewing machine, is a premium heavy-duty triple-transport lockstitch machine designed for sewing thick, multi-layer, and hard-to-handle materials with exceptional control and consistency.

Engineered for demanding production environments, the Z7 combines advanced AI thickness sensing, a high-torque 850W direct-drive motor, and fully automated functions to deliver smooth, reliable stitching—even when sewing over seams, overlaps, and sudden thickness changes.

This complete industrial sewing machine is ideal for leather, automotive upholstery, furniture manufacturing, bags, mattresses, and technical textile applications where precision and feeding power are essential.

Key Features & Benefits

Unison Feed / Walking Foot Needle Feed (Triple Transport)

The Z7 features a true unison feed (walking foot needle feed) system, where the needle, walking feet, and feed dog move together in sync. This ensures powerful, even feeding of thick, layered, or slippery materials—eliminating stitch length variation and material slippage.

Intelligent AI Thickness Control

An integrated AI chip continuously detects changes in material thickness and resistance, automatically adjusting motor torque and needle penetration force to maintain consistent stitch quality across the entire seam.

Dual Thickness Sensor System

The built-in thickness sensor automatically activates:

• The second alternating walking foot

• The additional thread tension device

This allows the machine to adapt instantly to height changes, overlaps, and dense seams without operator intervention.

Double Alternating Walking Feet

Two independently adjustable alternating walking feet can be:

• Activated automatically based on detected thickness

• Switched manually by the operator

Providing precise control and smooth feeding on variable materials.

Additional Thread Tension Device

A secondary thread tension system ensures balanced, consistent stitch formation, especially when sewing thick threads or multiple layers—reducing skipped stitches and thread breakage.

Automatic Double Stitch Length

With the push of a button, the machine automatically switches to a shorter stitch length for corners and detailed areas—improving accuracy and productivity without manual adjustment.

Touch Screen Control Panel

The intuitive touch screen panel with voice guidance allows fast access to:

• Thread trimming

• Back-tacking

• Presser foot lift

• Bartack functions

Advanced settings are available via long-press for full customization.

Electronic Digital Handwheel

The integrated electronic handwheel enables:

• Precise needle positioning

• Half-stitch operation at the touch of a button

Ideal for detailed sewing and accurate stitch placement.

Programmable Function Keys

Convenient function keys on the machine head provide quick access to frequently used operations. One key is fully programmable to suit individual workflow requirements.

850W High-Torque Motor

Powered by a robust 850W motor, the Z7 delivers exceptional penetration power and smooth performance, outperforming standard walking foot machines in heavy-duty industrial applications.

Pneumatic Presser Foot Lifter

The double-alternating pneumatic presser foot lifter ensures smooth, controlled lifting and lowering—improving efficiency when handling thick or multi-layer materials.

XXL 32mm Hook

The XXL 32mm hook offers 73% greater capacity than standard hooks, supporting thicker threads and longer continuous seams while reducing downtime.
