The SIRUBA Industrial Overlock Sewing Machine (Serger) is a premier, high-speed workstation globally recognized for its extreme durability and precision engineering in commercial garment production. This complete set comes fully integrated with a heavy-duty wooden tabletop, an adjustable steel T-leg stand, and a high-efficiency electronic servo motor. Operating at blistering speeds of up to 7,500 stitches per minute, the machine seamlessly trims raw fabric margins while binding the edge in a single pass. It features an advanced fully automatic lubricating system and a micro-adjustable differential feed to prevent fabric puckering on ultra-lightweight materials or over-stretching on highly elastic knits.

The machine setup is available in two distinct configurations to maximize factory floor versatility:

• 4-Thread Configuration (747 Series): Engineered with two needles and two loopers to produce a highly flexible, durable mock-safety stitch. It is the industry standard for assembling knitwear, athleisure, t-shirts, and stretch fabrics where the seam must expand with the garment.

• 5-Thread Configuration (757 Series): A true safety-stitch machine combining a 3-thread overlock edge with an independent, high-strength straight chain-stitch line. It is designed for maximum seam reinforcement on heavy or non-stretch woven apparel like denim, trousers, and uniforms.

Equipped with a modern servo motor, the entire workstation ensures near-silent idling, adjustable speed parameters, and an energy savings of up to 70% over standard clutch-driven industrial units.
