Jack C7-A-4-M03/333 Full Computer 4-Thread Multi-Material Overlock Machine
GUARANTEED SAFE CHECKOUT
Description
Discover the next generation of peak performance with the Jack C7-A-4-M03/333, a fully automatic 4-thread overlock machine designed to handle multi-material fabrics. The machine features a Stepper Motor-driven thread trimming and presser foot lifting system (not a traditional solenoid coil), ensuring faster response, quieter operation, and greater stability. Thanks to the advanced trimming system, the remaining thread tail is extremely short (only 5mm), eliminating the need for manual trimming and saving time. It utilizes Smart Rhino Feeding Technology, which provides significantly stronger feeding and torque (11.3 N-m torque, 0.001 N-m resolution) for precise feed force regulation, along with the Spider Thread Control System that dynamically manages thread tension balance. With a max speed of 7000 s.p.m and the ability to seamlessly sew hundreds of styles per day, it delivers a 15% comprehensive productivity increase and generates an extra $720 annual profit per unit, all while ensuring completely oil-stain-free sewing.
