- High-Speed Automatic 4-Thread Overlock Machine with Vertical Suction Device.

The Jack C5-4-M03/333/KS is a state-of-the-art pneumatic overlock machine, engineered for high-speed performance and intelligent automation. Equipped with three built-in photocells, it enables fully automatic sewing for improved workflow efficiency. Featuring fast response acceleration and deceleration, the machine delivers up to 50% quicker reaction times, enhancing precision and productivity.

Chaincutter Waste Suction (KS/KH)

The front suction system removes fabric scraps, while the rear suction captures trimmed threads—ensuring a cleaner work area and a tidy, professional seam finish.

Short Thread

An automatic electric cutter, controlled by photocells, ensures a precise 5mm thread cut at both the beginning and end of the seam—reducing waste and eliminating the need for manual trimming.

L/M/H Selector (Patented)

A convenient lever allows adjustment of the feed dog inclination to suit light, medium, or heavy-duty fabrics—adapting seamlessly to different materials and meeting diverse sewing requirements.

Vocal Guide

The machine offers interactive voice guidance that teaches you its various functions as you use it. In case of errors, it provides immediate notifications and, with a press of the VOICE button, suggests clear solutions. A single key also allows you to quickly return to the initial factory settings.

Speed Up to 7,000 RPM

Delivers a maximum sewing speed of 7,000 revolutions per minute—35% faster than standard machines—for significantly enhanced productivity and efficiency.

Durable Components

All main moving parts are made with anti-wear materials, ensuring long-lasting performance even under high-speed operation.

Industry 4.0 Ready (Optional)

With the integrated Wi-Fi module, you can remotely adjust machine parameters and monitor productivity in real time via the dedicated application.
