The invention relates to a sealing device (1) for sealing at least one underpressure or overpressure zone (6) adjoining a surface (3) which is moved in a movement direction (4) in a paper, tissue or cardboard machine, comprising at least one sealing element (10) which is located opposite the moved surface (3) and has at least one feed channel (11) for a lubricant. In order to considerably decrease the wear of a sealing element uniformly over the entire length thereof, the at least one feed channel (11) ends in a supply channel (12), which is arranged at the beginning of the sealing element (10) in the movement direction (4). |
