AUTEFA Solutions leads the way in carding technology The combination of flexibility, high line speed and process efficiency is mandatory for state-of-the-art carding technology. AUTEFA Solutions offers fully integrated turnkey lines including all components from fiber opening to web drafting. All process steps and corresponding machines are fully integrated into the AUTEFA Solutions control system. All cards are equipped with a controlled air flow using a vacuum system in order to minimise the flow of fibers. Easy access to all components of the card is provided by the Monoblock design of the machine frame allowing a quick and easy opening of the card. / 3
Injection Card The traditional mechanical carding principle using workers and strippers has been replaced by an aerodynamic principle in the Injection Card. The fibers are taken off the worker rollers by an aerodynamic effect generated by specifically shaped devices. This avoids considerable mechanical stress on the fibers which usually applies to traditional carding systems with stripper rollers. THIS PATENTED CARDING PRINCIPLE OF THE INJECTION CARD PROVIDES SOME VERY IMPORTANT BENEFITS: The carding action takes place at the tangent point of two convex surfaces and is very smooth. The fibers are not picked up by worker and stripper rollers minimising the fiber path. This reduces the mechanical and thermal stress on the fibers resulting in a significant reduction of neps, fiber breaking and melting. The fiber path is completely on the inside of the card reducing the negative effects caused by centrifugal forces. It is possible to run the main cylinder at maximum rotation speed to improve the web quality. Combined with the patented EVO-2 and EVO-3 take-offsystem, the Injection Card achieves very high production speeds with an excellent uniformity also with fine fibers. All cards are equipped with the new easy opening system. 4 /

WM 2+2 CARD The Webmaster WM 2+2 Card is designed for high productivity and top quality nonwoven materials. A patented system of two doffers between the two main cylinders of the WM 2+2 Card provides an optimal strip-off at the first cylinder and allows the division of the fiber flow in the intermediate area providing improved blending and fiber distribution on the second cylinder. In addition, the use of two doffers in the intermediate section increases the carding power of the machine with the effect of about two additional worker rollers compared to a traditional card. The standard configuration of the WM 2+2 Card is equipped with a double doffer delivery section. Each doffer of the delivery section is equipped with a randomiser which is quickly convertible to a rotary comb allowing the production of randomised webs as well as highly oriented webs on the same machine according to the material specifications. By using the One Web System the WM 2+2 Card can also be used to produce a single web suitable for the production of light weight materials. And all cards are equipped with the new easy opening system. 6 /

In addition to the traditional volumetric hopper feeder HF, there is a feeding system using a FCU filling cage transporting the fibers in a controlled way to the new volumetric control chute feed CF. This system provides an excellent uniformity in the feeding process at high production rates. FINE-OPENER FTO VOLUMETRIC HOPPER FEEDER HF FILLING CAGE FCU VOLUMETRIC CONTROL CHUTE FEED CF 8 /

Card Regulation Feeding systems of the card can be combined with an inline control of the weight of the fiber matt or alternatively by controlling the fiber density with the Servolap system (x-ray). The settings of the feeding system are automatically optimised based on the information provided by the inline control system. 10 /
Carding Competence Center The AUTEFA Solutions Carding Competence Center (CCC) possesses an industrial scale carding line for the production of needle punched nonwovens with a working width of 3.5 m, combining F.O.R. (carding), Autefa (crosslapping) and Fehrer (needle punching) technology. All process steps are fully integrated, in order to obtain top quality and maximum efficiency from bale opening to winding. Each unit, together with its relevant operating data, is displayed in a process control system for central operational und process control. A further 2.4 m width production line is available for airlay (aerodynamic carding), needled and thermobonded nonwovens. This technological diversity will furnish customers with a unique opportunity for targeted nonwoven product development. / 11
