Jack A4C-CH-7 | AI industrial straight stitch machine for heavy fabrics

Jack A4C-CH-7
Industrial flat-bed sewing machine with AMH1 artificial intelligence for heavy fabrics

The Jack A4C-CH-7 is the flat-bed version of the A4C range, designed specifically for sewing heavy fabrics: leather, technical materials, multi-layered fabrics, and padded garments. It combines the AMH1 AI chip and APE motor with the friction-free NTB thread path to eliminate thread breaks and automatically adapt to any thickness in real-time, without manual intervention. It replaces models A4, A4S, A4M, A4E, A4F, A4A, and A4B from the previous range.

Exclusive Technologies

• AMH1 AI Chip + APE Motor — the automatic material adjustment system detects fabric thickness in real-time and adapts penetration force and feed dog transport, ideal for heavy materials that require constant adjustments
• Flat Bed — specific configuration to facilitate the processing of heavy and multi-layered fabrics
• NTB System — Friction-Free Thread Path — reduces thread tension by 30% and breaks by 80%, crucial for thick threads and resistant materials
• Digital Stitch Length — precise adjustment from the panel with adjustment lock function
• 13-Level Digital Presser Foot Lift — adjustable from the panel with a click, useful for managing variable thicknesses typical of heavy materials

Operating Features
