JACK A4C C AI Octopus Nine Brain Chip! Single Needle Direct Drive Fully Automatic Drop Feed Lockstitch Industrial Sewing Assembled with Table and Stand Included

NEW 2025!! The Jack A4C‑C is a state-of-the-art single-needle lockstitch machine engineered for speed, precision, and advanced automation. Powered by Jack’s NTB system and Octopus “Nine‑Brain” AI chip, it optimizes fabric feeding in real time, reducing thread breakage and ensuring consistently high-quality stitching—even at high speeds.

Key Features

• NTB System with Octopus Nine‑Brain AI Chip: Processes over 200,000 fabric samples at 10,000 computations per second to dynamically adjust feed force and synchronize thread-taking, catching, and fabric feeding.
  
  
• 0‑Degree Thread Path Technology: Significantly reduces thread tension by up to 30%, minimizing friction and breakage.
• Stepper Motor for Presser Foot Lift and Reverse: Ensures exceptionally quiet operation and smooth control, carried over from the A4B-C design.
  
  
• Direct‑Drive, Energy‑Saving Motor: Built-in, quiet, and efficient for smooth, power-saving operation.
  
  
• Automatic Sewing Functions: Includes thread trimming, foot lift (up to 13 mm), back‑tacking, and needle up/down positioning for streamlined, operator-friendly performance.
  
  
• Enhanced Usability Features: LED lighting for better visibility and optional voice feedback to guide operation.
