One Day, One Threading — Powered By NTB System
Revolutionize your sewing experience with the Jack A4C, engineered for precision, speed, and smart automation. At the heart of this advanced machine lies the NTB System, a breakthrough technology designed to deliver unmatched threading efficiency and fabric control.
NTB System: Intelligence Meets Precision
Driven by the cutting-edge Octopus Nine-Brain AI Chip, the NTB System analyzes over 200,000 fabric samples with a blazing 10,000 calculations per second.
This high-speed processing delivers the optimal fabric-feeding force in real time, perfectly synchronized with other core mechanisms.
Through intelligent coordination of thread-taking, thread-catching, and fabric-feeding, the NTB System ensures seamless operation with exceptional stitch quality — even at high speeds.
Octopus Nine-Brain AI Chip
This powerful AI engine constantly learns and adapts to fabric types, ensuring flawless fabric feeding and stitch formation.
It’s like having nine brains optimizing every move — making adjustments on the fly to maintain performance and consistency.
0-Degree Thread Path Technology
Exclusive to Jack, this innovative threading system reduces thread tension by up to 30%, enabling precise thread handling and catching.
The linear, friction-reducing thread path ensures smoother operation, less breakage, and longer thread life.
