Abstract

A sealing device and process for laterally sealing at least one overpressure zone or underpressure zone adjacent to an actuating surface in a paper-making machine. The sealing device has at least one sealing element arranged movably at least locally in an intake area of a support. The sealing element is loaded with a sealing or opposing force in order to place it against the actuating surface. A stopping element is fixed at a distance from the actuating surface which limits the seating motion of the sealing element.
