Felting and structuring needles 

Felting needles are used to mechanically bond nonwovens in needling machines. Depending on the fiber type and the required properties of the end product, different needle types are available with regard to length, shape of the working part, and distribution or consistency of the barbs.

Groz-Beckert offers four different barb shapes. The dimension and shape of the barb are of great importance for efficiency during the needling process, they are used in transporting and bonding the fibers within the nonwoven. The formation of fiber loops makes the nonwoven increasingly dense. This results in higher fiber-to-fiber friction, which ultimately determines the final strength and volume of the nonwoven, as well as all of its other mechanical properties.

With structuring needles, a distinction is made between fork needles and crown needles. Their task is to structure already-bonded nonwovens in special machines. The surfaces are given a velour or ribbed look, with geometrical or linear patterns.

To fulfil the high requirements of the most diverse applications – e.g. surface quality, tear resistance, uniformity, minimal damage to fibers and carrier material, and long service life – Felting needles are used with different working part shapes.

Working part shapes

The Twisted felting needle with twisted working part is especially suitable for the production of articles with high tear forces.

The EcoStar® felting needle features an entirely new development in working-part geometry, which can be used in almost all applications.

Tri STAR® needles are distinctive for their concave working part sides with more acutely angled edges. This provides better fiber transport due to the enhanced grip of fibers in the barb. Fiber transportation is improved, leading to more intensive needling.

Cross STAR® needles are especially suitable for the needling of higher product weights. They achieve uniform material properties and the highest tensile strengths in both the length and cross directions.

Reduced penetration force when piercing the product, high stability as well as good needling effects, achieved via larger barbs – those are the special features of the vario barb needle. Lower deflection and less needle breakage are guaranteed.

The advantages of felting needles with conical working parts in relation to standard working parts lie above all in the higher stability.

GEBECON® felting needles from Groz-Beckert offer the ideal combination of good end product surface quality plus the best possible resistance to bending.


The special feature of Groz-Beckert GEBEDUR® needles is their high wear resistance.



Thanks to the high number of suitable needle types with different barb sizes, barb shapes, working part gauges and working part cross sections, Groz-Beckert offer the ideal felting needle for all needled filter media.

Application-related problem areas, such as the production of paper-machine felts and filter felts, require a high degree of gentleness where the needled product is concerned. Here, a teardrop shaped working part offers the ideal prerequisites.

Fork needles have a shank with reduced thickness plus a cylindrical working part. The important functional element is the fork opening on the working part.

Crown needles are designed in the same way as felting needles. The only difference lies in the barb arrangement. Located on each edge of the working part is typically only one barb. The short distance from the tip to all three barbs is virtually identical. Formation of the loop thus takes place uniformly, resulting in a homogeneous surface.
