Aq-vanes: A new technology for stratified forming
RISE, STFI-Packforsk.
2004 (English)In: ATIP. Association Technique de L'Industrie Papetiere, ISSN 0997-7554, Vol. 58, no 6, p. 17-19Article in journal (Refereed) Published
Abstract [en]

STFI-Packforsk has recently patented the "Aq-vanes", a new technology for stratified forming headboxes. In this new solution, a thin passive liquid layer (or "Aq-vane") is injected in the headbox between neighbouring pulp streams through a narrow hollow channel. Thereby mixing between the layers is prevented and the process becomes controllable by tuning a set of process parameters. The Aqvanes have been implemented for extensive pilot scale trials on EuroFEX, STFI-Packforsk's research paper machine. Thereby a number of technical solutions for the injection of the liquid layer has been tested and evaluated.
