Siruba U007‑W122‑356/UCH‑3M/UTT/DSKH1‑1 – Ultra-Compact 3‑in‑1 Cylinder‑Bed Interlock Machine
The Siruba U007 series represents top-tier performance in ultra-small cylinder-bed interlock sewing machines. With a 128 mm diameter and 64 mm depth, this compact design effortlessly handles narrow tubular garments—such as children’s clothing, sleeve cuffs, or pant hems—that are difficult to process on conventional machines. The sharp entrance throat enhances material insertion and removal, reducing setup time and allowing a smoother workflow
The machine’s advancement in fabric handling owes much to its reinforced feed‑dog mechanism, which delivers durable, consistent feeding across a variety of fabrics. This ensures smooth stitch formation and high seam quality, even on small circumferences, without compromising fabric integrity
An automated trimming system, combining both pneumatic and electric controls, provides precise, clean thread cuts with low noise and easy adjustments. Integrally mounted on the left side, this auto‑trimmer significantly reduces manual intervention and improves production cycle times
Designed for versatility, the UCH‑3M model features a 3‑in‑1 folding system supporting general seaming, bottom hemming, and cover stitching. This multi‑mode capability allows manufacturers to leverage a single machine for diverse finishing tasks, optimizing space and reducing investment in multiple specialized units
A user‑friendly circular stitch‑length dial makes on‑the‑fly adjustments fast and intuitive. Combined with a maximum operating speed of 2500 stitches per minute, the machine sews a 300 mm circumference in under 3 seconds—an impressive metric for small‑cylinder applications
Technical sheet from Siruba’s Latin America distributor confirms additional specs:
Needles: twin‑ or three‑needle configurations
Threads: 4‑ or 5‑thread interlock stitch
Drive: direct‑drive servo motor
Speed equivalent: up to 2700 rpm in some variants; typical productivity ~ 2500 rpm
The machine achieves up to 5000 mm/min feed speed (approx. 83 m/min) and a maximum stitch length of 5 mm, ideal for lightweight to medium-weight knits and tubular fabrics
5 Key Advantages
Ultra-small cylinder bed (128 mm × 64 mm): tailor-made for children’s garments, sleeve cuffs, and other narrow tubular components.
3-in-1 multifunction flexibility: easily switch between general seam, bottom hem, and cover stitch functions via fold-down system—reducing the need for multiple machines.
Automatic pneumatic/electric trimmer: provides precise, quiet, and adjustable thread trimming to improve cycle efficiency and seam quality.
Exceptional speed and control: stitch 300 mm circumferences in under 3 seconds at up to 2500 rpm, with straightforward circular stitch-length adjustment.
Enhanced durability and feeding performance: robust feed-dog design supports consistent fabric handling, minimizing skipped stitches and improving operator confidence.
