For nonwovens production, maximizing the evenness of the product across the entire production line is one of the key success factors. The weight profiling product range of Andritz – consisting of ProDyn and ProWid – has been extended by ProWin. This new development is the combination of the 2 previously existing systems.
It allows nonwovens producers to achieve optimum weight profiling at the crosslapper delivery and increase their process speed by up to 15% at the same time. ProWin combines the long-term process experience and in-depth knowledge international technology group Andritz AG, Graz/Austria, has on needlepunch lines with innovative software to synchronize action across the line.
The self-regulating, advanced technology reduces fiber deposits at the edges of the web and eliminates the “smile” effect across its width. ProWin enables producers to optimize the CV ratio autonomously and precisely. Fiber savings of up to 10% and increasing production speed can also be generated.
