Needle Punching Technology

Needle punching machines or needle looms, are essential in the production of nonwoven fabrics. Nonwovens are bonded mechanically by needling. The needles punch vertically in and out of the material, interlocking the fibers thru the use of the barbs on the needles. The felt is driven through the needle zone via the drive of the delivery rolls. 

AUTEFA Solutions product range 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 long-time experience with the latest technology and offer optimum solutions for any kind of needling requirement, as single machines or integrated in complete lines.

Needleloom Stylus NL

AUTEFA Solutions Stylus NL needlelooms are highly versatile and offer medium needle densities for pre-needling and ensure enhanced performance through increased penetration density for finish-needling. All single, double and four board needlelooms are based on a highly rigid welded steel frame in the proven and well-established Fehrer quality. The machines are suitable for all types of natural, synthetic, and recycled fiber batts and are in operation all over the world to create first class needlepunched nonwovens. Combined with one of the well proven and tested Fehrer feeding systems the Needlelooms Stylus NL are the perfect pre-needling solution wherever light or heavy pre-needling with or without elliptical needling is required.       

Needleloom Stylus VARILIPTIC

The design of the Needle Loom Stylus is tailored to customers’ requirements in terms of working width, maximum machine load and machine speeds achievable. A pneumatic needle board clamping is fitted as standard, with the added option of integrating a quick-exchange system for stripper and bed plate. The Needle Loom Stylus can work with conventional needling zone arrangements, with one or two boards from top (downstroke) or bottom (upstroke), one from top and one from bottom or two from top and two from bottom, or even in a tandem arrangement. The whole series uses exactly the same parts. Spare parts can therefore be used without any problems in all Stylus needle loom configurations and not as many needs to be kept in stock. The slim design of the Needle Loom Stylus allows existing nonwoven installations to be upgraded with Variliptic drive technology.

 

Needleloom Stylus ONE

Needlelooms from AUTEFA Solutions combine Fehrer’s know-how and long-time experience with the latest state-of the-art technology. AUTEFA Solutions offers the optimum solution for any kind of needling requirement, as single loom or integrated in complete lines. The Needleloom Fehrer StylusONE covers market needs for a reliable and economic machine, suitable for all needling applications up to 1.800 gms.

Each machine is 100 % pre-tested which allows a fast start-up.         

i-POINT Simulation tool for needle board pattern

An improved and even surface quality has been set as key target by our customers. Therefore, AUTEFA Solutions offers the service of a customized needle board pattern. The i-Point needling simulation tool increases the capacity and the quality of needlepunched fabrics. The development of new needle patterns and the evaluation of surface quality is much more effective and economic with the i- Point software technology. It creates a layout of stripper and bed plate including the elliptic needling (Variliptic). This customized design of needle pattern, which takes also draft and shrinkage into consideration, reduces the process optimization time on customer site. AUTEFA Solutions needlepunch lines produce an even and homogenous fabric with outstanding technical performance in terms of tensile strength and evenness (MD/CD ratio).  

Automatic Needle Exchanger

With the Automatic Needle Exchanger 2.0 AUTEFA Solutions has a unique service machine for every needleloom. The Needle Exchanger enables a fully automatic process of needle rotation and exchange without manual intervention. The machine exchanges single, all, or user defined segments of needles. The Automatic Needle Exchanger 2.0 offers an unprecedented level of needle management. The machine fits into every service workshop and increases efficiency and economy.  Some of the key figures are an operating speed of up to 1,500 needles/h and a needle magazine for more than 10,000 needles. For removing and setting of needles no direct involvement of operating personnel is necessary.
