Conical Needle Used In Automotive Industry, Artificial Leather, Geotextile, Filter Felt, Etc

Short Description:

Conical needle, also known as strengthening needle, it not only has all the characteristics of triangle needle, but also has greater bending force, greater elasticity, can withstand greater needling force, needle wear-resistant, long service life, so it can improve the penetration efficiency.

Selection range

• Needle size: 20, 23, 25, 32, 36, 38, 40, 42

• Needle length: 3 ” 3.5″ 4″ 4.5″ 4.8″ 6″

• Barb shape: G GB B

• Other shapes of working parts, machine number, barb shape and needle length can be customized

The diameter of different parts of needle is indicated by gauge. The smaller gauge meams the larger diameter. When in the working part, the cross-section height is indicated by working part gauge. The cross-section height of conical working part is measured on the position of 5mm from needle point. The other cross-section shape is measured by their height.

Features

*The needle is composed of three foliage, the needle is perpendicular to the length of the conical triangular needle on any position of the cross section are triangular, from the needle tip to the needle waist direction of the front end of the needle gradually coarsening
*The cone Angle increases significantly from the tip to the end of the working site
*The size of the barbs on each edge is graded: the closer to the tip, the smaller the barbs are
* A plurality of barbed hooks are arranged helically on the three edges of the needles, and the tip of the barbed hook is oriented toward the direction of the tip of the needle.The conical needle can reduce the probability of breaking needle,reduce calorific value and avoid fiber damage on the premise of guaranteeing the penetration power

Advantages

*More uniform bending strength, better elasticity, better stability than standard needles (fewer broken needles), higher production speed, reduce net offset
*Less initial puncture resistance, resulting in better needle guidance, less deflection, and fewer broken needles
*The number of hooks is large, the load is not too high, the bending performance is better, and the possibility of needle breaking at the back of the working part is lower
*Better surface quality of processed products (smaller funnel-shaped dents in finalproducts)
*Less machine load
*Reduce the contamination of needle, needle plate, supporting plate and stripping plate when processing recycled fiber
