Energy Saving
Thanks to the built-in Eco Motor servomotor, it achieves up to 71% energy savings, ensuring efficient and quiet operation.Jack JK-8558G-1-WZ is a high-speed industrial single-needle, two-thread chainstitch sewing machine with bottom fabric feed and a built-in energy-saving low-vibration, low-noise motor. Chainstitch machines are mainly used in sewing operations where an elastic stitch is required, reliable for clothing subject to stretching during wear, such as side seams on trouser legs. They are especially recommended for long seams because loopers allow stitches to be formed directly from the thread spool, eliminating the need for frequent bobbin changes. Two-thread machines are used for formal wear production, such as reinforced seams on men’s trousers or linen seams, as well as lap seams. LED workspace lighting is included as standard.
