Jack K7 | AI-powered Coverage

Jack K7
AI-powered cylinder bed coverstitch machine with 9.2 Nm and nano-ceramic thread guides

The Jack K7 is the AI-powered cylinder bed coverstitch machine in the Jack range. Its AI chip detects real-time variations in fabric thickness and automatically adjusts penetration force and feed — without manual adjustments — ensuring perfect seams on any material, from the lightest to the heaviest. The 9.2 Nm feed torque (+12.5%) and speed up to 6,000 rpm (+10%) make it the most powerful and fastest in its class.

Key Technologies

• Adaptive AI chip — detects thickness in real-time and calculates optimal parameters with artificial intelligence algorithms: no adjustments needed for heavy, light, or stretch fabrics
• 9.2 Nm feed torque (+12.5%) — ultra-high feed force for heavy and multi-layer materials
• 6,000 rpm speed (+10%) — -1.5 dB noise and -30% vibration compared to the previous generation
• Nano-ceramic thread guides — 30% reduction in thread resistance, 80% fewer snags in difficult passages

Operational Features

• Rhombic arm — 20 mm presser foot from the edge — easy material insertion even in the narrowest areas
• New panel with Italian voice guidance — quick keys for thread trimmer, thread nipper, needle up/down, LED light, presser foot lifter, stitch condensation, and reset
• Control box with Hurricane handwheel — simulated airflow duct that lowers the control box temperature by 15°C compared to the K5E, reducing heat-related failures by 40%
