Saurer Group, a leading textile industry group specialising in machinery and components for yarn processing, has followed the path to sustainability with Autoconer 6 , the new automatic winding machine, by The Saurer Group Business Unit Spinning brands Schlafhorst and Zinser, that works on E3 strategy, which follows zero wastage of energy and raw materials.

The target of zero waste in the winding process is realised by the Autoconer 6 more effectively than any other automatic winding machine. It consumes up to 20 per cent less energy than its predecessor, reduces yarn waste, and saves on compressed air. With its E3 concept, Schlafhorst consistently exploits potentials to achieve feasible savings.

Zero yarn waste operating cycles in winding processes causes waste. Schlafhorst has therefore reduced the number of cycles through a reliable yarn pick-up system, avoidance of tension breaks and economical yarn clearing that concentrates on the clearer cuts that are absolutely necessary.

The zero waste concept would not be complete without having the possibility of reusing valuable yarn residues, which can therefore be collected separately from dust in the Autoconer. With its FX technologies, in particular PreciFX, the Autoconer is able to produce packages that are optimally prepared for downstream processes. This does away with rewinding processes, for example during dyeing, that cause yarn loss.

In the new Autoconer 6, maximum performance efficiency is ensured thanks to the Eco-Drum-Drive system, high-slide energy-saving bearings and motors that meet the IE3 standard. Vacuum production is another important factor in the energy budget of a winding machine. The Autoconer 6 works with a significantly lower vacuum requirement than other automatic winding machines, while maintaining maximum process stability. Progressively shorter cycle times have reduced the energy consumption of successive Autoconer generations.

Thanks to the process-optimised package design enabled by PreciFX, there is no longer any need for rounding-off before the dyeing process or for the rewinding of hard packages to dye packages and vice-versa. Finally, with optimally structured packages the energy-intensive dyeing process itself becomes more efficient through an optimised liquor ratio and maximum capacity utilisation of the dyeing equipment.

Zero wastage of compressed air is mainly used for cleaning the machine. With an open design, in which all areas are easily accessible, Schlafhorst has succeeded in significantly reducing the cleaning requirements. (GK)
