The Siruba DL720G-BM1-1 is a high-performance, industrial single-needle lockstitch sewing machine designed to meet the demands of light to medium-weight fabric sewing. This machine is equipped with an advanced energy-saving Direct Drive servo motor integrated directly into the machine head on the main shaft. This design reduces vibration and noise, improves energy efficiency, and ensures smooth, precise operation. The Direct Drive system also eliminates the traditional belt-driven bobbin winder, relocating the bobbin winding mechanism directly to the head of the machine, which leads to quieter operation and enhanced machine durability.
This model is engineered for high productivity, capable of sewing up to 5000 stitches per minute with a stitch length adjustable up to 4 mm. It features a bottom feed dog transport system that delivers consistent fabric feeding, ensuring uniform stitch quality across various materials. The presser foot lift is 13 mm, providing ample clearance for thicker seams or layered fabrics, which increases the versatility of the machine for different sewing applications.
The Siruba DL720G-BM1-1 is equipped with a fully functional thread trimming system, which automates the cutting of the upper and lower threads, thereby saving operator time and increasing workflow efficiency. Additional operator-friendly features include needle positioning for exact stitch placement, a slow start function to prevent thread breakage at the start of sewing, and an easy-to-use stitch length adjustment button conveniently placed near the needle bar. For improved working conditions, the machine includes LED lighting focused on the sewing area, enhancing visibility and reducing eye strain during detailed sewing tasks.
Centralized lubrication ensures that the machine’s critical components receive optimal and consistent lubrication, extending the lifespan of the machine and reducing maintenance requirements. The needle system used is BDx1 (16×231), a widely accepted standard, ensuring easy replacement and compatibility with various needle types suitable for different fabrics.
The Siruba DL720G-BM1-1 is delivered as a complete setup with the sewing head, energy-efficient servo motor, a high-quality worktable, a stable base, and a convenient operator drawer for tools and accessories. This comprehensive configuration makes it an excellent choice for garment manufacturers focused on efficiency, reliability, and quality in their production lines.
