Siruba ASK-ACS200
The Siruba ASK-ACS200 is a specialized 4-thread cylindrical overlock sewing machine designed specifically for sewing collars (stands) on T-shirts. This advanced machine combines precision, speed, and automation to deliver consistent high-quality results suitable for mass production in the garment industry. Its specialized design allows for automatic positioning of the collar before sewing, which significantly reduces manual labor and increases efficiency while ensuring accurate alignment for each piece.
Equipped with a double differential transport system—incorporating both lower and upper transport mechanisms—the ASK-ACS200 ensures smooth fabric handling and prevents puckering or distortion during sewing. The double differential feed is particularly effective for managing the stretch and knit fabrics commonly used in T-shirt collars, maintaining even tension and precise stitching throughout the operation.
The machine operates at a high sewing speed of 4,000 stitches per minute, enabling rapid production with an estimated output of 180 to 240 collars per hour. This efficiency makes it ideal for large-scale manufacturing environments requiring both speed and consistent stitch quality.
The ASK-ACS200 uses a 2-needle system with 4 threads, featuring a needle spacing of 2 mm, an overcast width of 4 mm, and a total stitch width of 6 mm. The machine is capable of sewing welt widths from 15 to 30 mm, with welt circumferences between 450 and 800 mm and material thickness ranging from 1.2 to 1.6 mm. These technical specifications enable the machine to accommodate a broad range of collar sizes and fabric types typically found in sportswear and casual apparel production.
To operate efficiently, the machine requires a connection to compressed air with a pressure of 0.5 MPa and air consumption of approximately 35 liters per minute. It runs on a standard 230V power supply and uses B27 #11 needles, known for their durability and suitability for sewing medium-weight knit fabrics.
The Siruba ASK-ACS200 combines advanced mechanical engineering with user-friendly features, including easy maintenance and setup, making it a reliable choice for manufacturers aiming to improve production throughput while maintaining excellent product quality. This machine represents a smart investment for factories specializing in T-shirt manufacturing, delivering precision, speed, and consistency.
