AUTEFA Solutions Needle Punching Lines

Needle punching machines, or needle looms, are essential in the production of nonwovens. Nonwovens are mechanically bonded by needling. The needles punch vertically into and out of the material, interlocking the fibers by using the barbs on the needles. The felt is driven through the needle zone by the drive of the feed rollers.

The product range of AUTEFA Solutions includes single and double board needlelooms, tandem needlelooms, velour, structuring and patterning needlelooms based on the Needleloom Stylus NL drive concept series and the Needleloom Stylus VARILIPTIC drive concept. Needlelooms from AUTEFA Solutions combine Fehrer's know-how and many years of experience with the latest technology and offer optimum solutions for every kind of needling requirement, as single machines or integrated in complete lines.

At AUTEFA Solutions we understand the importance of high-quality products. That is why we have developed our 3-level Closed Loop Control System, which allows customers to monitor and improve web quality in real time. One of the key components of our system is a scanner that determines the weight distribution of the final product. This information is then used by the control system to correct the profile in the crosslapper and the infeed section of the card. The result is a very uniform distribution of the carded web, which is essential for producing high quality products.

This process is optimized by the WebMax web profile control system and several measuring points throughout the line. This WEBMAX profiling is integrated into our 3-level Closed Loop Control System, which ensures that the fabric is uniformly profiled in both machine direction and cross direction. Profiling is a unique edge treatment. It results in fewer edge-related problems and makes felt life more predictable and even longer. 

The elliptical drive of the Needle Loom Stylus Variliptic is still the unique solution for draft reduction and improved CV values for all quality grades of needling. The horizontal stroke is continuously adjustable during the needling process. Unlike other machines on the market, the Stylus Variliptic requires only a single compact drive. The Variliptic drive increases needle life and minimizes the risk of needle breakage. It optimizes the surface of the nonwoven fabric while protecting the fibers and minimizing needle wear.
