JACK C5C-4 Auto

The Jack C5C‑4 Auto is a high‑performance 4‑thread industrial overlock sewing machine designed for professional garment production, tailoring workshops, and fabric finishing lines. Built with advanced automatic functions and a direct‑drive servo motor, this machine delivers quiet, energy‑efficient operation with minimal vibration, making it ideal for continuous use in busy environments.

This overlock model features automatic thread trimming, automatic presser foot lifting, automatic needle positioning, and sensor‑based controls that allow seamless transitions between stitches without the need for a foot pedal. The machine also incorporates photocells that detect fabric presence to automatically start and stop sewing and allow automatic activation of the cutter and foot lifter — significantly boosting productivity and reducing manual steps.

Designed to handle light to medium fabric types like knitwear, T‑shirts, sportswear, and stretch materials, the Jack C5C‑4 Auto provides smooth overlock seams with minimal thread waste — thanks to precise trimming and tension control. Adjustable settings for fabric thickness make it adaptable to various stitching needs, while voice assistance and user‑friendly controls help operators work efficiently with less training time.
