Siruba 747K-514M5-23/BKF/DKLHD1-3 – Advanced 4-Thread Overlock Sewing Machine with Automatic Trimming and Chain Securing
The Siruba 747K-514M5-23/BKF/DKLHD1-3 is a highly specialized 4-thread overlock machine designed primarily for sewing light to medium-weight fabrics with precision and efficiency. This model incorporates an advanced automatic trimming system controlled by a photocell sensor, ensuring precise and timely thread cutting either automatically or manually via a button. The machine is equipped with a programmable chain securing system, allowing customizable stitch chain length, thread tension, and securing depth, enhancing seam strength and finishing quality.
The chain securing system operates up to three times faster than traditional manual methods, and can minimize securing depth to approximately 1 cm, making it ideal for delicate applications such as high-quality lingerie where minimal bulk is critical. Additional features include an integrated waste suction system that removes thread and material debris during sewing, keeping the workspace clean and preventing fabric contamination. The automatic presser foot lifter simplifies material handling and improves workflow efficiency.
Equipped with a modern, energy-efficient integrated servo motor, the machine delivers high sewing speeds of up to 7,500 stitches per minute while maintaining quiet operation and energy savings. It uses a differential bottom feed mechanism for consistent fabric handling and supports needle system B27 with a needle spacing of 2 mm. The overedging width is 3 mm with a total stitch width of 5 mm, making it suitable for a wide range of garment construction needs. The machine requires a 230V power supply and connection to a compressed air source to operate pneumatic functions.
