Description

JACK E4S High-Speed Direct Drive Overlock Sewing Machine

High-speed industrial overlock sewing machine designed for efficient seam finishing and garment production on light, medium and selected heavy-weight materials. The JACK E4S is equipped with an integrated energy-saving direct-drive motor and advanced feeding system for smooth, stable and reliable sewing performance.

A key feature of the JACK E4S is its L/M/H material selector, which allows the feed mechanism to be adjusted for light, medium or heavy fabrics. This helps improve feeding performance across different material thicknesses without complicated mechanical adjustments. The differential feed system also helps prevent stretching, puckering and distortion, particularly when sewing knitted and elastic fabrics.

The machine features an integrated oil system with a closed needle-bar mechanism designed to reduce oil leakage and help keep garments clean during production. Its high-speed operation, intelligent control panel, LED lighting and direct-drive motor make it suitable for modern garment manufacturing environments. The E4S Series is available in 3-thread, 4-thread and 5-thread configurations depending on the specific model.
