- Most common number of barbs: 2 barbs per edge
- Working part side concave in shape,creating more acutely angled edges
- 8% lower working part cross-section compared to the standard needle
Benefits
- Higher needling efficiency due to improved fiber entanglement in the barb area
- Suitable productiviity increase
