Open-type Needle

The working section of the open-type felting needle has an equilateral triangular cross-section, providing uniform bending strength in all directions. It is commonly used for processing ceramic fiber insulation materials.

open type felting needle 001

Features

  • The working part cross-section is an equilateral triangle
  • Working part parallel from the point to the tapered transition
  • Between 1 and 3 barbs along each edge as standard

Benefits

  • Uniform deflection in every direction of load
  • Improvement of the surface aspect(smaller funnel-shaped recesses in the end product)compared to conical felting needles
  • Reduction of machine load
  • Less soiling during waste fiber needling(of felting needles,needle board,base plates and stripper plates) compared to conical needles
  • Reduced penetration force at the start,resulting in improved needle guidance,lower deflection and less needle breakage.
