Siruba DT828-42-064ML/DTU – High-Performance 2‑Needle Lockstitch Machine with Energy‑Saving Direct‑Drive Servo
The Siruba DT828-42-064ML/DTU is the latest iteration in Siruba’s 2‑needle lockstitch series, designed specifically for sewing light to medium‑weight fabrics. With its fixed needle bar and small loopers, it provides an optimal balance between simplicity and capability—ideal for continuous stitching operations where needle switching is unnecessary. This model maintains a needle spacing (gauge) of 6.4 mm, suiting general garment construction. Custom needle gauges are also available for those with specific production needs
At its core, the machine employs a Direct-Drive servo motor integrated into the machine head, delivering multiple production benefits: up to 60 % energy savings compared to clutch motors, precise needle positioning, and a soft-start feature at the beginning of sewing cycles, enhancing both energy efficiency and thread stability
The servo system also ensures quiet operation with minimal vibration, contributing to improved operator comfort and reduced fatigue.
One of the machine’s notable enhancements is its advanced looper adjustment system, enabling faster and simpler changes in needle gauge. This innovative mechanism reduces downtime and allows for quick reconfiguration between different garment widths . Siruba has also upgraded the system with a closed-loop lubrication mechanism, which continuously delivers oil to critical machine components—particularly the hook and feed mechanisms—resulting in smoother operation, reduced wear, and longer service life
Seam quality is further refined by the inclusion of a double thread tension system for both needles. This allows precise calibration of stitch tension when working with diverse thread materials or fabric types, ensuring consistent seam strength and appearance across all production runs
The machine supports an impressive sewing speed of up to 3600 stitches per minute, with a maximum stitch length of 4 mm, handling everything from delicate fabrics to stable woven or knit materials .
Constructed with dual feed—both needle and feed dog—the DT828 ensures reliable material traction, reducing puckering and optimizing stitch accuracy, especially useful when working with slippery fabrics or during topstitching applications
A horizontal-axis rotary hook and sliding thread take-up lever further enhance stitch formation, while a see-through window allows easy monitoring of bobbin thread quantity. For operator convenience, standard features include LED lighting, reverse stitching function, and a user-friendly stitch-length adjustment dial .
Operating at standard 230‑volt power, the machine integrates seamlessly into typical industrial workshop electrical setups while offering substantial energy cost savings thanks to its efficient motor technology. With its smart engineering and durable build, the Siruba DT828-42-064ML/DTU delivers dependable, high-speed performance and consistent stitch quality—an ideal choice for mid-volume apparel production environments requiring cost-effective reliability.
