Autefa Solutions will tell visitors all about material and energy efficiency, and the processing of renewable and recyclable fibres at INDEX 2014 that will take place from 8-11 April in Geneva.

Dr Stefan Schlichter, CEO of Autefa Solutions explained: “At INDEX we present latest technologies and developments that support and secure the success of our customers. The technologies and machines of Autefa Solutions stand for continuous process improvements and ensure a significant increase in product quality.”

The show focus is on lines for the manufacturing of fibres such as flax, bamboo, coconut and ramie. For this application the use of the Aerodynamic Web Forming Machine Airlay Card K12 DIRECT is particularly effective here, the company reports.

 It is a short and compact machine and is said to enable a gentle fibre treatment. The renewable fibres are used to create voluminous, three dimensional nonwoven fibres that are then processed into composites, for example with propylene or polyester in the top and bottom layer.

The Airlay Card K12 DIRECT is suitable for the production of top quality webs in a weight range of 80 g/m2 to 6,000 g/m2. Due to the direct transfer from the chute feed to the Airlay Card, without an additional opener, the fibres are gently opened and formed into the nonwoven fabric.

For the nonwovens industry the fibre recycling concept of Autefa Solutions offers all components from a single source and, according to the company, enables a competent and effective realisation of the individual steps. Core components of the recycling line are high performance fibre balers and a compact tearing machine.

The Webmaster Card works on basis of a patented double doffer system between the two main card cylinders and offers two main advantages. It maximizes the production of the cards and improves the blending and fibre distribution on the second cylinder, facilitating improved product quality even at high production rates.

The Crosslapper Topliner is a key machine in many nonwoven installations. According to Autefa, it increases the product quality in new installations or as a replacement in existing lines. It increases the weight of the product and improves the MD/CD ratio and the web strength.

With Webmax minor draft corrections can be made between the card and the Crosslapper. In this way the so-called smile-effect, namely the increased weight of the fabric in the edge areas, created by material shrinkage through drafting and speed accelerations, can be prevented via the Webmax compensation system. This results in a considerable savings in  raw materials, the company reports.

The Stylus needle loom is equipped with the innovative Variliptic drive system, which enables high production speeds while also ensuring a gentle needling of the nonwoven fabric.

This is particular important during the first process step, the preneedling. According to Autefa, the Variliptic drive system optimises the surface of the nonwoven fabric, while also protecting fibres and minimising the needle wear.
