Dual Feed (Top Feed System)
The lower and adjustable upper feed dogs ensure synchronized movement of both fabric layers. This completely eliminates layer shifting, prevents puckering across cross-seams, and avoids unwanted pleats.
Energy-Saving Servomotor (Direct Drive)
The built-in energy-saving direct-drive servomotor guarantees stable, quiet, and reliable overlock operation. Direct drive significantly reduces sewing vibration and cuts electricity consumption.
Jack JK-798TE-5-516-A04/435 is a high-speed industrial 5-thread overlock with a built-in servomotor, designed for high-quality seaming and overedging of dense materials. The model is equipped with a dual feed (lower and adjustable upper feed dog), which guarantees perfect layer movement without the formation of folds and creases. Electronic control, high operating speed, and quiet, smooth running make this overlock the optimal choice for working with medium to heavy-weight materials.
