Siruba C007L‑W822A‑356/CRL/CHP/UTP/CL/RL/DCLH1‑ – Advanced 3‑Needle Coverstitch Machine
The Siruba C007L-W822A is a specialized ultra-high-speed, three-needle, five-thread cylindrical coverstitch (drabinkowa) machine optimized for hemming tubular garments—especially T-shirt bottoms, underwear, and sportswear. The “CRL” designation indicates a left-side knife that trims the hemmed fabric edge, improving seam precision and cleanliness during sewing
. The “CHP” denotes the automatic pneumatic hem folder for consistent, even fold handling. Built on the C007L platform, it offers state-of-the-art features such as the recessed cylinder bed and oil-sealed design
Powered by a servo motor integrated into the machine head (Direct Drive system), this model enables needle positioning, automatic pneumatic upper thread trimming (UTP), CL rear roller puller, and right/left loop knife functionality. The “RL” feature (roller tensioners) supports elastic, “in-the-round” sewing by maintaining tension—ideal for attaching stretch waistbands or elastic bands
A pneumatic system actively suctions trimmed material scraps, keeping the workspace clean.

Why It Stands Out
CRL Knife on the left ensures the hem edge is neatly trimmed during sewing.
UTP & CHP Pneumatic Control automate hard-to-reach functions for higher throughput.
CL Rear Puller maintains consistent fabric/elastic tension for uniform seams.
Integrated Servo Motor in the head reduces noise, saves energy, and improves responsiveness.
Oil-Sealed Frame and recessed cylinder bed offer enhanced clean sewing environment and longevity.
Key Bullet Points
Left-side CRL knife for automatic edge trimming during sewing.
Pneumatic CHP hem folder ensures clean, consistent fold handling.
UTP upper thread cutter for automatic trim at seam end.
CL roller puller & RL tensioners support elastic “in-the-round” sewing.
Integrated servo drive + direct pneumatic automation deliver high efficiency and operator comfort.
The Siruba C007L-W822A offers a powerful blend of precision trimming, elastic handling, and productivity enhancements—ideal for advanced production lines in sportswear, underwear, and tubular knitwear manufacturing.
