Siruba 747 High-Speed 4-Thread Overlock Sewing Machine

High-speed industrial overlock sewing machine designed for seam joining, edge finishing and garment production. The Siruba 747 Series is a 2-needle, 4-thread overlock machine widely used for sewing light- to medium-weight fabrics, knitwear and general garment materials.

The machine uses a differential feed system to provide smooth and controlled fabric movement, helping prevent stretching, puckering and distortion during sewing. Its high-speed mechanism delivers consistent stitch formation and high production efficiency, making it suitable for continuous industrial use.

The Siruba 747 Series is available in different subclasses and configurations, with the common 747L-514 configuration producing a 4-thread overlock safety stitch. Its reliable construction, smooth operation and versatile fabric handling make it a popular choice for garment factories and tailoring production units.
