JACK E4S-3

The Jack E4-3 sewing machine is a 3-thread overlock equipped with an energy-saving servo motor built into the head (Direct Drive system). This solution ensures quiet and reliable operation as well as lower energy consumption. Compared to older generation machines with clutch motors, the JACK overlock uses up to 75% less power.

The modern design provides better motor ventilation, significantly improving its performance and extending its lifespan. The machines feature an easy-to-use control panel and integrated LED lighting (with 3-level light intensity adjustment).

The latest E4S-4 model is equipped with an additional lever for adjusting the height of the feed dogs. This adjustment allows for quick and easy adaptation of the machine to different types of materials. The setting can be adjusted to one of three available positions:

A (very light and light materials) M (light and medium materials) H (medium and heavy materials)
