The Siruba 757L-516X3-56/DKLU is a robust 5-thread overlock machine with a direct needle drive, specifically designed for sewing heavy and thick materials such as upholstery, denim, and workwear. It features a differential feed system with bottom feed teeth and a special jointed presser foot, which facilitates smooth sewing over cross seams and thick fabric layers. The reinforced feed system ensures consistent fabric movement and precise stitch formation even under demanding conditions.
Equipped with a modern, energy-efficient servo motor mounted directly on the machine’s main shaft (Direct Drive system), this machine offers quieter operation with significantly reduced energy consumption — up to 75% less compared to traditional clutch motors. Integrated LED lighting improves visibility of the workspace, enhancing precision and user comfort. The centralized lubrication system contributes to long-lasting performance and durability.
