Voith innovation for positioning of edge deckles in suction rolls

摘要

Voith's latest development, TrackLight, makes it possible to easily adjust edge deckles, meaning optimum machine performance can be achieved immediately after grade change or start-up. An unique lighting system allows the operator to instantly identify precisely the edge deckle location and adjust the width of the suction zone relative to the paper web. Until now, edge deckles could only be adjusted by an experienced operator. Improper positioning can cause various operating challenges and add costs: high vacuum energy costs due to a gap between paper web and end deckle. When operating with a vacuum zone that is too narrow, edge flipping is typically a result and this impairs machine efficiency.
