Autefa processing solutions on display in Atlanta

Autefa Solutions, a full line supplier for carded- crosslapped needlepunch lines, aerodynamic web forming technology, spunlace, and thermobonding lines, will present the economic and technical advantages of its latest solutions at this week’s Techtextil North America, in Atlanta, GA.

The recently delivered complete line to IDEAL Automotive, an international system supplier and development partner for the automotive industry, covers the need of the highly-competitive automotive market. High-speed and an improved quality have been set as key targets by the customer.

At Techtextil, Autefa Solutions will show innovative solutions for the processing and recycling of carbon-, glass-, aramid- and natural fibres. Since 2010 the company is concerned with the re-utilisation of recycled carbon fibres to carbon fibre nonwovens and has already successfully placed production lines in the market.

Airlay K 12

In the construction, residential and automotive market, efficient thermal and acoustic insulation materials are key factors that contribute to energy saving and to the reduction of natural resources consumption. The aerodynamic web forming process with Autefa Solutions random card Airlay K 12 stands for an improved MD:CD ratio and a 3D web structure.

During the process, the fibre material is opened up to the single fibre; this enables a high versatility regarding fibre choice. The Airlay K 12 has been developed to offer the special advantages when it comes to lighter weights and high loft fabrics. The increased opening capabilities distinguish itself for PET, as well as fiberglass fibre processing.

Stylus needle looms

Based on the long-standing experience of the former company Fehrer in Linz, Austria, Autefa Solutions delivers innovative Stylus needle looms with the Variliptic drive concept (elliptical needling) and with the NL drive for vertical needling. The Stylus needle loom is said to improve the web quality, by reducing the draft especially in the pre-needling process, increase the machine durability and minimise maintenance.

AstenJohnson, a leading manufacturer for the paper industry, has invested in a new line. Autefa Solutions has delivered a complete needlepunch line with nonwovens carding system Masterfelt, crosslapper Topliner and two over 13 m wide needle looms Stylus Variliptic and Stylus NL.

“Our customers like the extremely reliable and robust Stylus series. The machines are often heavier and bigger than other needle looms in the market. The advantage of our design offers vibration free running, needle densities up to 30,000 needles per meter and highest production due to stroke frequencies up to 3,000 rpm in continuous operation,” commented André Imhof, COO Autefa Solutions.

Energy saving spunlace solutions

Autefa Solutions has developed and patented the V-Jet injector, installed in several productions, leading to significantly higher tensile strength at same entangling water pressure than a standard injector. The possible reduction of water pressure is in the range of 20 %. In addition, the water consumption is reduced by 10 % when using the same nozzle diameter and pitch.

“The new Square Drum Dryer SQ-V combines the advantages of a horizontal dryer with the lower space requirement of a conventional drum dryer. The nozzle system uniformly distributes the airflow in terms of speed and temperature throughout the whole working width, providing best spunlace web and surface quality results,” the company explains.

Complete lines for manufacture of ADL

Autefa Solutions delivers machines for opening, blending and carding, as well as ovens and dryers out of one hand. Autefa Solutions high-speed oven HiPerTherm HS offers approved accuracy airflow system with high production speeds up to 250 m/min. It is a single belt oven for thermobonding and drying. The double nozzle system allows the creation of extremely uniform product treatment.

The machine has been especially designed for the manufacturing of top sheets and ADL what demands utmost accuracy. The nozzle design prevents dust accumulations and ensures the capture of dust in the automatic filter systems.
