The Jack E4S-5 is a high-performance 5-thread industrial overlock (safety stitch) machine designed for strong seam construction and clean edge finishing in one operation. It is equipped with an integrated direct-drive servo motor, ensuring quiet operation, reduced vibration, and significant energy savings compared to traditional machines.
This machine is built with a modern mechanical structure that enhances motor ventilation, improves durability, and supports high-speed production environments. The 5-thread safety stitch system provides extra strength, making it ideal for garments that require both seam joining and edge finishing, such as jeans, uniforms, and workwear.
The E4S-5 also features an adjustable feed system (L/M/H selector), allowing operators to easily switch between light, medium, and heavy fabrics for consistent stitching quality. Its user-friendly control panel, LED lighting, and stable feeding system make it a reliable choice for industrial garment production.
