Abstract (en)
Method and system for the stabilization of paper applicable in a dryer section of a sheet of paper (1) that is conveyed along with a fabric (5), where there is at least one critical area (7) in which they (1, 5) separate from each other. The method comprises at least the steps of generating a high circulation vortex (12) in the critical area (7) and confining the high circulation vortex (12) in the critical area (7). This way, a high vacuum is in turn confined in the critical area (7) that prevents the separation of the sheet of paper (1) and the fabric (5), without having to use confinement elements that are aggressive to the fabric (5), and with reasonable energy consumption.
