ProWin is the latest development from Andritz for ensuring web evenness. As nonwoven webs are laid and processed, the fibers tend to move to the edges of transportation belts and individual machines, leading to the so-called ‘smile’ effect and a lack of homogeneity in the web if not constantly corrected.
Andritz has developed ProWin that maximizes the evenness of nonwoven fabrics across the entire line. The new technology allows nonwoven producers to achieve optimum weight profiling at the crosslapper delivery and increase their running speed by up to 15%. The new unit complements the company’s existing ProDyn and ProWid profiling units.
Andritz also offers a range of service apps for maximizing production. The Metris Cost Management app is used to track raw material consumption, allowing in-depth diagnosis of raw material losses and savings achieved in the different process areas.
Guillaume Julien, head of needle punch sales at Andritz Nonwoven, said, “We have developed a self-regulating, advanced technology to reduce fiber deposits at the edges of the web and eliminate the ‘smile’ effect across its width. ProWin enables producers to optimize the coefficient of variant – CV – ratio autonomously and precisely while also generating significant fiber savings of up to 10% and increasing production speed. As such, it provides a fast return on investment.”
