The LS20-3 Overlock Seaming Sewing Machine is a high-performance industrial solution specifically engineered for the demanding requirements of FIBC (Flexible Intermediate Bulk Container), Jumbo Bag, and Big Bag manufacturing. Based on the versatile GN20 series, this machine excels in executing the 502 overedging stitch, ensuring superior edge stability and seam strength for heavy-duty industrial fabrics.
Designed for maximum efficiency, the LS20-3 offers a wide overlock width and a robust mechanism capable of handling exceptionally thick threads without compromising performance. Whether you are producing heavy-duty bulk bags or specialized industrial textiles, the LS20-3 provides a cost-effective, stable, and professional-grade alternative to complex combined-stitch machines, streamlining your production line for maximum output.
| Model Series | LS20-3 (GN20 Series) | Stitch Type | Overedging Stitch (502) |
|---|---|---|---|
| Over Seaming Width | 10-12mm | Needle Configuration | Single Needle |
| Thread Capacity | 2 Threads | Primary Application | FIBC / Jumbo Bag Overlock |
| Material Compatibility | Very Thick Industrial Threads | Performance Level | High Stability/Heavy Duty |
| Machine Category | Industrial Overlock Sewing Machine | Comparative Class | Simplified 81300 Alternative |
Engineered to handle very thick threads and heavy industrial fabrics with consistent tension and strength.
Optimized for rapid overlocking of FIBC bags, reducing cycle time in big bag production lines.
Offers a more affordable price point than 81300 machines for users who only require overlock functions.
Features a professional 10-12mm over seaming width for maximum edge security and durability.
Precision-engineered components ensure low vibration and high stability during continuous industrial use.
Part of a family including carpet and fishing net versions (LS20-2 to LS20-5) to suit any textile need.
Efficiently integrate the LS20-3 into your FIBC assembly line for seamless edge finishing.
Low-maintenance design reduces downtime and ensures long-term operational reliability.
Precise 502 stitching prevents fraying, meeting strict international FIBC quality standards.
Compatible with a wide variety of heavy-duty industrial threads for diverse material needs.
Simplify your machinery park by selecting specialized overlock units for specific bag types.
User-friendly interface allows operators to master the machine quickly with minimal training.
| Feature | LS20-3 (Overlock) | 81300 (Combined) | Generic Machines |
|---|---|---|---|
| Initial Cost | Low / Economical | High / Premium | Medium |
| Stitch Function | Overlock Only (502) | Overlock + Chainstitch | Basic Overlock |
| Material Strength | Excellent (Heavy Duty) | Superior (Double Secure) | Average |
| Operational Speed | High Efficiency | Medium-High | Low to Medium |
| ROI Period | Fastest Return | Moderate Return | Slow Return |
The primary difference is the stitch capability. The 81300 combines Overlock and Chainstitch, whereas the LS20-3 focuses exclusively on the Overlock (502) stitch. This makes the LS20-3 more affordable and ideal for production lines that only require overedging.
Yes, the LS20-3 is specifically designed for heavy-duty applications. It features a robust mechanism that can stably process very thick threads required for FIBC and Big Bag manufacturing.
The LS20-3 provides a professional over seaming width of 10-12mm, ensuring strong edge reinforcement for industrial bulk containers.
While the LS20-3 is optimized for FIBC bags, the GN20 series is versatile. Depending on the specific model (like LS20-2 or LS20-4), these machines can also be used for carpets, fishing nets, and other heavy-duty textile overlocking.
For fishing net overlock requirements that include a puller, we recommend the LS20-5 model, which is specifically configured for that application.
By providing a specialized, high-speed overlock function at a lower purchase price than multi-function machines, the LS20-3 reduces initial capital expenditure and lowers the cost per unit during the sewing process.
